TLS (Transport Layer Security) and SSL (Secure Sockets Layer) are cryptographic protocols that allow making secure connections from an FTP client to a server with SSL capabilities. The server sends the client a certificate and a public key for encryption. If the client accepts/trusts the server's certificate, an SSL connection can be established. When an SSL connection is established, all data passing from one side to the other will be encrypted and will only be able to be decrypted by the parties involved in the transfer of data.

When both a client and server support SSL or TLS, the utilization of security is accomplished through a sequence of commands passed between the two machines.

The FTP protocol definition provides at least two distinct mechanisms by which this sequence is initiated: Explicit (active) and Implicit (passive) security.

Explicit: This type of security requires that the FTP client issues a specific command (AUTH SSL or AUTH TLS) to the FTP server after a connection to establish the SSL link has been made. The default FTP server port is used.

Implicit: This is a mechanism by which security is automatically turned on as soon as the FTP client makes a connection to an FTP server. In this case, the FTP server defines a specific port for the client (990) to be used for secure connections.

1. Go to Start > Settings -> "Control Panel."

SmartFTP is an FTP client that allows you to connect to an FTP server. An FTP client cannot directly connect to another FTP client. In order to share files, an FTP server as an intermediary is required. You can either install an FTP server on your computer or you can sign-up for a web hosting plan which offers you this service. 

Setup FTP server on your computer
This option requires a bit of technical know-how and a preferably a permanent Internet connection if you want others to connect to your server. Take a look at the list of FTP servers.

Sign-up for a web hosting plan
A web hosting provider typically offers you a place where you or others can store files on the Internet. In this case the web hosting provider manages and runs the FTP server. To share files with other parties the files needs to be uploaded to the FTP server first.

• Test Maximum Connection Speed
  It is important that you test your connection speed since it has the highest influence on transfer speeds. You can test your connection speed, tweak it, and get additional help on the following sites:
  www.dslreports.com/speedtest
  www.speedguide.net
  www.pcpitstop.com
• Turn on Mode Z Compression
  Mode Z compresses files on the fly as they are being transferred, saving bandwidth and improving transfer time. The server needs to support Mode Z nevertheless. For further information please refer to the following knowledge base article:
  KB: MODE Z / zlib
• Fine tune the Receive and Send Buffer sizes
  In some cases changing these transfer buffer sizes can make a difference; in particular in transfers over high loss, high speed connections where latency plays an important role. For more information on Buffer Sizes and how to change them refer to the following knowledge base article
  KB: How To change Transfer Buffer Sizes

• Install SmartFTP onto the target machine.
• Create a new registry key on the target machine. The "Application Data Folder" can be set in the registry: HKEY_CURRENT_USER\Software\SmartFTP\Client 2.0\Settings\General > "Application Data Folder".
• You can use an environment-variable like "%UserName%" and "%APPDATA%" so that the value is something like "%APPDATA%\SmartFTP\Client 2.0".
• This is expanded to "C:\Documents and Settings\mb\Application Data\SmartFTP\Client 2.0" on my computer.
• If you create the registry key/value on your own, make sure the type is set to "REG_EXPAND_SZ".

Error

When trying to connect to a SSL/TLS server you might encounter the following error:

Solution

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the Favorites window select the Favorite to be used. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under FTP > Connection select SSL.
4. Under the Client Certificate click on the Create Cert button and follow the wizard to create a self-signed certificate.
5. Once completed, select it from the drop down box and click OK to save the changes. You will need to close the remote server window and reconnect back to the server.

1. To change a file's permissions, left-click on the file or directory to highlight it.
2. Right-click on the file and a pop-up menu appears. Choose "CHMOD" and type in the number manually (ex: 444) or use the check boxes.
3. You can also enable the "Command Line" window, which will allow you to send raw commands directly to the server.
4. To find the "Command Line" select View > Toolbars > Command Line from the SmartFTP menu. The "Command Line" when enabled, will be viewable under the "Log View" window.

• Both FTP servers must support FXP and have it enabled. Please consult with the server administrator since most FTP servers do not support FXP, or have FXP disabled due to potential security risks.
• One server has to support PASV mode and the other server must allow PORT commands from a foreign address. The client logs in to both servers and then it arranges for a file transfer by telling one server that it will be a passive transfer and the other that it will be an active transfer, see example.

Example
The FTP client tells the destination FTP server to listen for a connection by sending a "PASV" command. The source FTP server connects to the data port reported by the destination server (after a successful PASV command). The client then passes the address/port in a "PORT" command to the destination server. Thus all the data goes directly from the source to the destination FTP server. Both servers only report status messages on fail/success to the FTP client.

SmartFTP Client is written in C++ and developed with Microsoft Visual Studio 2005. The latest version also uses components from the xtreme Toolkit Pro from Codejock Software for the Graphical User Interface (GUI).

500 SITE not understood
500 Unkown command
500 SITE CHMOD command not understood
502 Command 'SITE' not implemented

500 FEAT not understood

Cause

The error is displayed as a reply from the server during login because the server did not understand the command just sent. This is because the server does not support the "FEAT" command. The majority of the time this error can be ignored as it is not a critical error and should not interfere with your transfers. The "FEAT" reply varies from server to server since it displays the current features that the server supports.

If you are experiencing problems with the "FEAT" command being sent to the server during the login process, you can disable the "FEAT" command:

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the Favorites window select the Favorite of interest. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under the FTP option select Connection. From the Connection tab under Control Connection disable the " Send FEAT " option.

500 Illegal PORT Command
500 Illegal PORT range rejected

Cause

The FTP server is blocking foreign IP's or high ports often required for FXP transfers.
If SmartFTP cannot resolve the problem on its own during an FXP attempt, the server needs to be configured to allow foreign IP's in PORT command and allow high ports.

In a non FXP connection enable the Passive Mode.

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the SmartFTP Favorites window select the Favorite of interest. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under the FTP option select Connection. From the Connection tab under Data Connection you can enable the Mode passive (PASV) for the selected Favorite.

Current Session Setting

1. Click the "PASV" button on the toolbar when connected to a server.
2. You can also Switch between Active and Passive mode from:
   Menu: Commands > Connection -> "Passive Mode".
   

There is a problem with the server's configuration or server's system you are connected to. The server's system site has a maximum of N connections on the TCP/IP layer (Windows 9x: N=100). The maximum number of connections is easily reached when 20 users log in to the site and each user uses about 4 connections. It could be that the connections are not closed right after the user quits.

There are hidden MSTCP registry settings where the maximum number of connections can be changed. Further details on hidden MSTCP registry settings can be found in the the Microsoft KB article: Q158474

Change the maximum number of connections by editing:
Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP MaxConnections = 32-bit number Data Type: DWORD

For Windows 98, the Data Type is a String value that specifies the maximum number of concurrent connections. The default number is 100.

Note: If the DWORD MaxConnections is not there you will have to manually create it in:
Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP
Set the MaxConnections DWORD to 500.

No year specified (all UNIX style servers)

drwx------ 2 4659 100 512 Jan 30 21:46 .
drwx------ 2 4659 100 512 Jan 30 21:46 ..
-rw-r--r-- 1 4659 100 3765 Jan 30 21:46 index.html

In this case, either the current year or the previous year is assumed, depending on the current date: "March" is interpreted as March '98 in February '99, whereas it would be interpreted as March 99 in May 99.

Two-digit only:

03-04-98 07:00PM <DIR> Explorer
03-05-98 04:24PM <DIR> Netscape

If the year is in a two-digit notation, years >= 50 are considered 19xx and years < 50 are considered 20xx.

Problem
Always logs in as anonymous instead of using the username and password.

Solution
You need to enter your server login information, there are several ways of doing so:

• From the New Remote Browser Dialog (recommended). Select File > New Remote Browser from the SmartFTP menu. The New Remote Browser Dialog appears. Fill out the rest of the login information.
  


• Enter the full URL ftp://user:password@host.com:port into the URL field. The separate user/password fields on the right side are ignored. Eg. ftp://smartftp.com does connect as anonymous.
  


• Enter the host only into the URL field and enter the username and password information into the input box on the right. If you want to login as anonymous check the [x] Anonymous checkbox.

You can use "SmartFTP.exe /?" for help.

Additional commands are available through the SmartFTP Command Line Interface addon.

• One possibility is that you are trying to connect to the server with Implicit SSL, when the server requires an Explicit SSL connection. On the Address field, to the left hand side, next to the word "Address" you will see a icon with a drop down arrow, select "FTP Over SSL (Explicit)" from the drop down menu.
• Another possibility is that you need to upgrade to MSIE 5 or higher, which contains the domestic 128 bit encryption. The update can be obtained at the www.windowsupdate.com web site.
  Once you have updated your Internet Explorer to version 5 or higher, you have to create a "self-signed" certificate:
  From the menu of Tools > Settings -> "SSL"
• This can also occur when connecting to an incorrect port, or the server just does not support SSL.

SmartFTP can no longer be used for free for personal purpose. To use SmartFTP after the 30-days evaluation period you are required to purchase a license:
http://www.smartftp.com/buy.php

1. Select Tools > Settings from the SmartFTP menu. The Settings window appears. From the Settings window select Backup. From the Backup tab you can select to Backup Now or set it up so that SmartFTP backups automatically at a specified time interval.
2. Alternatively, from the Windows Start Menu select > All Programs > SmartFTP client > Tools > Backup Tool. Follow the instructions on the screen to perform a successful backup of your favorites, history, etc.

550 - No such file or directory
550 - Permission Denied.

Cause

This error message is coming from the FTP Server you are connected to, 550 errors are always permission errors. The text that follows 550 varies from server to server. The 550 error means that you do not have access rights to transfer (download/upload) the file. This also pertains to making new folders on the server or uploading files to the server. Please contact the server administrator for further details.

Problem:

The HTTP:// Address I enter does not work.

Solution:

SmartFTP is not a web browser and does not currently support (HTTP). The http:// prefix is for programs like Internet Explorer, Netscape Navigator or Opera.

For SmartFTP, you need to use the prefix ftp:// . So connecting to an ftp server will look like: ftp://smartftp.com/

Problem

530 Logon failure

Cause

530 errors come from the FTP server. The server is rejecting the username/password you entered. The reasons could be an incorrect username/password combination or your account got disabled.

Double check your username/password (e.g. is Caps Lock disabled?). You get this information when you register for a web hosting service. If you are still experiencing problems contact the FTP server administrator. The FTP server is usually owned by a web hosting company (e.g. Yahoo, 1&1, etc). Contact the technical support of this company for assistance.

How To

1. Select Tools > Settings from the SmartFTP menu. The Settings window appears.
2. From the Settings window select Interface. The Show passwords option is located under General on the Interface tab. Check this option
3. Exit SmartFTP and relaunch it, you will see that the password is not hidden anymore.

1 bit = a 1 or 0 (b)
4 bits = 1 nybble (?)
8 bits = 1 byte (B)
1024 bytes = 1 Kilobyte (KB)
1024 Kilobytes = 1 Megabyte (MB)
1024 Megabytes = 1 Gigabyte (GB)
1024 Gigabytes = 1 Terabyte (TB)

Common prefixes:
- kilo, meaning 1,000. (one thousand) 10^3 (Kilometer, 1,000 meters)
- mega, meaning 1,000,000. (one million) 10^6 (Megawatt, 1,000,000 watts)
- giga, meaning 1,000,000,000 (one billion) 10^9 (Gigawatt, 1,000,000,000 watts)
- tera, meaning 1,000,000,000,000 (one trillion) 10^12

The smallest amount of transfer is one bit. It holds the value of a 1, or a 0. (Binary coding). Eight of these 1's and zero's are called a byte.

Why eight? The earliest computers could only send 8 bits at a time, it was only natural to start writing code in sets of 8 bits. This came to be called a byte.

A bit is represented with a lowercase "b," whereas a byte is represented with an uppercase "b" (B). So Kb is kilobits, and KB is kilobytes. A kilobyte is eight times larger than a kilobit.

A simple 1 or 0, times eight of these 1's and 0's put together is a byte. The string of code: 10010101 is exactly one byte. So a small gif image, about 4 KB has about 4000 lines of 8 1's and 0's. Since there are 8 per line, that's over (4000 x 8) 32,000 1's and 0's just for a single gif image.

How many bytes are in a kilobyte (KB)? One may think it's 1000 bytes, but its really 1024. Why is this so? It turns out that our early computer engineers, who dealt with the tiniest amounts of storage, noticed that 2^10 (1024) was very close to 10^3 (1000); so based on the prefix kilo, for 1000, they created the KB. (You may have heard of kilometers (Km) which is 1000 meters). So in actuality, one KB is really 1024 bytes, not 1000. It's a small difference, but it adds up over a while.

The MB, or megabyte, mega meaning one million. Seems logical that one mega (million) byte would be 1,000,000 (one million) bytes. It's not however. One megabyte is 1024 x 1024 bytes. 1024 kilobytes is called one Megabyte. So one kilobyte is actually 1024 bytes, and 1024 of those is (1024 x 1024) 1048576 bytes. In short, one Megabyte is really 1,048,576 bytes.

There is a difference of about 48 KB, which is a decent amount. If you have a calculator, you will notice that there is actually a 47KB difference. There is a difference of 48,576 bytes, divided by 1024, and you get the amount of real kilobytes... 47.4375

All of this really comes into play when you deal with Gigabytes, or roughly one billion bytes. One real Gigabyte is actually 1024 bytes x 1024 bytes x 1024 bytes...1,073,741,824. However, most people like to simplify this by simply saying that one Gigabyte is only 1,000,000,000 (one billion) bytes; which makes sense because the prefix Giga means one billion.

425 Can't open data connection error

Cause

The 425 error means that the data channel is blocked or closed between you and the server you are trying to connect to.

• For Active connections open ports 20 and 21
• For Passive connections open ports 21 and 1024+ (and higher)

NAT (Network Address Translation) is not the only factor that prevents you from using SSL/FTP with a firewall.

Firewalls are usually configured to deny inbound connections to the FTP server using any port other than port 21. Under PASV FTP, the firewall that protects the server needs to be able to see the un-encrypted response to the PASV command in order to allow inbound connectivity to the server on a dynamic port (i.e., ports other than 21).

This step will fail when PASV mode is used because the FTP Control session is encrypted. The new inbound FTP Data connection will arrive at the firewall and will be denied because it cannot be "bound" to an existing FTP Control Session.

The firewall needs to be able to read the encrypted PORT and PASV commands and re-write them with the proper IP address and port info when the firewall is performing NAT.

Problem
I am receiving the following message:

426 Connection closed; transfer aborted

Cause
There may be a local firewall blocking the connection or a problem with your ISP's network.

Solution
Try switching between Active Mode / Passive Mode and try again. For more information on how to switch between Active and Passive mode please refer to the following Knowledge Base article.
KB: How To switch between active and passive mode

SFTP over SSH is supported in SmartFTP version 3.0. Please download and install the newest version from:
http://www.smartftp.com/download

Problem
I uploaded a text file to an FTP server and found that the size of the file on server is smaller than the local one.

Solution
You are connected to a UNIX server. SmartFTP automatically detects that you are transferring an ASCII file and by default transfers it in ASCII mode, whereby the UNIX server will convert it to UNIX text format. While a line in the text file of DOS format has a Line Feed and Carriage Return pair (LF/CR), the UNIX format only has a line feed. That is why the size becomes smaller after the text file is uploaded.

1. Log into XP with your administrator account
2. Open Control Panel
3. Open Network Connections
4. Right-Click Local Area Connection (or the correct connection that you use for Internet connectivity - modem or dial-up for example)
5. Select Properties
6. Click the Advanced Tab
7. Uncheck the Protect my computer network by limiting...
8. Click "OK." You have just disabled the built-in Firewall and you should now be able to connect. Keep in mind that you may need to enable the PASV option in your SmartFTP client to connect successfully.

An established connection was aborted by the software in your host machine. Software caused connection abort.

This error can occur when the local network system aborts a connection, such as when WinSock closes an established connection after data retransmission fails (receiver never acknowledges data sent on a data stream socket), possibly due to a data transmission timeout or protocol error.

You may try to set the Connection Timeout higher (Default: 60s). If the problem persists change the Data Connection Mode from "Port Mode (PORT)" to "Passive Mode (PASV)" or vice versa. For further information on how to switch between Active and Passive mode please see the following Knowledge Base article:

Yes you can advertise SmartFTP on your website and use the graphics, logos and images which SmartFTP provides. If you have created a button, banner, or logo, feel free to contact us about it.

550 index.htm: Cannot create file

• The file already exists and is in use so you cannot overwrite the file.
• You do not have permission to create the file in the directory where you are currently located. A file upload is being attempted but the remote server has denied the needed permission.  The 550 error code is a result of insufficient account privileges on the remote FTP server.  The error is not caused by SmartFTP. If you believe that your FTP account privileges or permissions are configured incorrectly, contact your Web hosting company for help.

Unlike other products, you can try SmartFTP without risking your privacy. SmartFTP does NOT contain any advertising technology (so called "adware") nor does it display advertisements of any kind.

A firewall is a system designed to reinforce the Security of the data flowing between two Networks, the Internal Network and the outside Network. There are several ways to accomplish this but most firewalls use two or more of the following methods as none of them alone provides adequate security.

Packet Filtering:
Works at the Internet protocol layer and enables you to accept, reject or drop packets based on IP Address, Ports or Protocols. Packet filters perform these duties based on a set of configurable rules called Policies. Packet filtering is the original and the most basic type of firewalling and most routers provide packet filtering. Disadvantages of packet filtering however are:

• Address information on a packet can potentially be spoofed or falsified.
• The data contained in allowed packets can't be checked so they ultimately may contain exploits.
• Packet filters can't provide application level or user level authentication.
• Once a particular protocol is allowed to pass, external hosts can establish a direct connection to hosts on the Internal Network using that protocol. It could therefore expose the private Network configuration to everyone outside of the Network and reduce Network security.

Application gateway:
Applies security mechanisms to specific applications, such as FTP and Telnet servers. This is very effective, but can impose a performance degradation.

Circuit-level gateway:
Applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.

Proxy server:
Intercepts all messages entering and leaving the network. The proxy server effectively hides the true network addresses.

SmartFTP automatically resumes interrupted file transfers. There is no user intervention necessary.

1. Connect to the server
2. In the Remote Browser (server window) right-click on the file you want to edit
3. Select Edit from the context menu.

Problem:
Strange characters such as "^M" appear at the end of lines of transferred ASCII files.

Solution
This happens when ASCII files (such as those ending in .html, .htm, .cgi, or .txt) are transferred in binary mode. Perform the transfer in ASCII mode to prevent this from happening.

Most non-PC machines use just a linefeed character to indicate the end of a line in a file. PCs use carriage return and linefeed characters, so the carriage return (^M) remains at the end of every line as an artifact.

You can specify by file extension the file types that should always be transferred in ASCII mode. Auto is the default Data Transfer Type, and sends files in binary mode to and from FTP servers running on MS Windows. For non-Windows servers binary mode is used unless the file matches an entry in the ASCII File List. It is recommended that you leave your Data Transfer Type in Auto. For more information on how to do this, please read the following Knowledge Base article:
KB: ASCII / Binary Mode

You can convert from windows encoding to UNIX encoding using a text editor. This can be done easily with a utility such as Ultra Edit or Crimson Editor etc..

• Right-click on the file/folder, then select the Rename from the context menu.
• Alternatively, select the file/folder and press the F2 key on the keyboard.

• The server you are connected to must support the CHMOD command.
• You must have access rights to change the attributes of that remote file or directory.

You can specify by file extension the file types that should always be transferred in ASCII mode. Auto is the default Data Transfer Type, and sends files in binary mode to and from FTP servers running on MS Windows. For non-Windows servers binary mode is used unless the file matches an entry in the ASCII File List. It is recommended that you leave your Data Transfer Type in Auto.

Remember that Binary mode should be used and ASCII mode avoided since it is incompatible with resuming and file checks that play an important role in reliable transfers. The use of a text editor that supports Unix line endings it is recommended as well.

How To

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the SmartFTP Favorites window select the Favorite of interest. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under FTP select ASCII / Binary. From the ASCII / Binary tab under Default Transfer Type select the transfer method.
4. To transfer specific file types in ASCII mode, select Use Favorite Settings under the ASCII File List drop-down option.
5. Click on the New button and type in the file extension that will be transferred in ASCII mode under Value.
6. You can also use regular expressions (regexp) for the Type entries. For more information please see

Problem

SmartFTP wants to connect to www.saupdate.microsoft.com [207.46.131.229], port 80.

Cause

It is afeature in Windows XP triggered when an SChannel (Microsoft SSL Library) client receives a digital certificate signed by a untrusted Certificate Authority (CA). This feature allows Microsoft (not you) to control which certificate authorities you trust by dynamically updating the list of trusted CA in your Windows XP. This can be disabled by removing "Update Root Certificates" from Add/Remove Windows Components in Control Panel (Q283717).

The color coded file/folders is a feature that lets you know which file/folder(s) have been just added or updated on the remote server.

Legend
The red color indicates the files/folders that have been just uploaded to the server.
The blue color indicates files/folders that have been just changed on the server.

On December 30, 2001 Microsoft stopped supporting Windows 95, making it even less reliable than before. Windows 95 is an older operating system, and is therefore inherently less reliable and secure. Because old and unsupported software such as this goes against our core philosophy, SmartFTP will cease to support Windows 95 to coincide with the introduction of our upcoming versions of SmartFTP. There are no plans to discontinue support for any other Microsoft operating systems at this time.
Windows Life Cycle

SmartFTP proudly supports Windows 2000/Windows XP/Windows 2003.

1. Check that the destination IP address is valid. If you used a hostname, check that it resolves to the correct address.
2. If using a local host table for hostname resolution, check to see that it does not resolve to an obsolete address.
3. Try to ping the hostname.
4. Check the router configuration and that its working properly. Check that the router is working by pinging it, then ping an address outside of the router.
5. Use the tracert command at the command prompt to determine the path to the destination address and to check that all the routers are functioning.
6. Check your subnet mask. If you do not have the correct subnet mask, your network system might treat a local address as a remote address (so it forwards addresses on the local subnet to the router, rather than broadcasting an ARP request locally), or vice versa.
7. Increase the connection timeout threshold under Favorite Properties > Connection: from the SmartFTP Favorites window select the Favorite of interest. Right click on the Favorite and select Properties. The Properties dialog appears. Select the Connection option where server timeout settings can be changed.

• Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.

We are always working hard trying to improve SmartFTP. Please use the "Update Check" feature found on the Tools menu, to check for updates. You can also check our website from time to time for updates. The latest version of SmartFTP is available from: http://www.smartftp.com/download

Purpose

Normally, when one searches for a sub-string in a string, there has to be an exact match. Hence, if one searches for a sub-string "abc" then the string being searched for has to contain these exact letters in the same exact sequence for a match to be found. One can extend the search to be case insensitive where the sub-string "abc" will also find strings like "Abc", "ABC" etc. That is, the case is ignored but the sequence of the letters has to be exactly the same. However, a case insensitive search is not enough sometimes. For example, if we want to search for a numeric digit, one basically ends up searching for each digit independently. This is where regular expressions come to help.

Regular expressions are text patterns that are used for string matching. Regular expressions are strings that contain a mix of plain text and special characters to indicate what kind of matching to do. Here is a very brief tutorial on using regular expressions.

Special Characters

Examples

Important Notes

In SmartFTP's regexp implementation all chars are handled case sensitive.

HTTP/1.0 403 Forbidden.

Solution
The problem is due to the proxy server you are trying to use. It does not have the "Connect" method enabled. SmartFTP only supports the http proxy "Connect" method. The proxy works fine in Internet Explorer since it uses the "GET" method that treats the FTP like a web page. SmartFTP does not support this method. In order to use SmartFTP with your proxy, the proxy server needs to be reconfigured to support the "Connect" method.

When the "Port IP Mode" setting is set to "Auto", the IP Repeater is enabled.

This feature will attempt to assign the correct IP address for the PORT command using an https (port 443) connection to repeater.smartftp.com to get the external IP.

This feature should only be enabled if the NAT router does not replace the internal IP in the PORT command with the external IP. This is usually the case when the connection is made to a port different than standard FTP port (21).

AUTH TLS
500 Protocol not supported.

Problem

SmartFTP automatically sends an explicit command AUTH SSL and AUTH TLS to the FTP server to initiate a secure control connection. If the previous error occurs, it means that the server does not support SSL/TLS.

Solution

Please switch the Server Protocol from SSL to Normal FTP. For more information on how to do this please see the following Knowledge Base article:
KB: How To make a secure connection
If the problem still occurs after switching to Normal FTP, please contact your server administrator for further details.

For more information on explicit or implicit SSL please see the following Knowledge base article:
KB: What is the difference between implicit and explicit SSL

SSL (Secure Sockets Layer) is a protocol for transmitting data between a client and a server  via the Internet that uses a cryptographic system designed to prevent eavesdropping, tampering and message forgery that might occur during a regular FTP transfer.

How To select the Protocol

To create a secure connection you have the following options:

Quick Connect

1. In the menu select File - New Remote Browser
2. Select the protocol from the Protocol selection

Address Bar
You can directly select the preferred protocol in the address bar:



From a Favorite

1. Select Favorites - Edit Favorites from the menu. The Favorites Browser appears.
2. From the Favorites Browser window select the Favorite to be used. Right-click on the Favorite and select Properties from the context menu. The Properties dialog appears.
3. Select General. In the the General dialog change the Protocol.

If a Windows Error Report dialog shows up please choose to send the crash report by following the instructions in the dialog. This will allow us to track bugs easier and continually improve SmartFTP.

SFTP over SSH (SSH2) is supported in version 3.0. You can download it from:
http://www.smartftp.com/download

To open a SFTP over SSH session: 

1. Go to the menu: File -> New Remote Browser
2. Select SFTP over SSH in the protocol combo box
3. Enter the host and username/password as provided by your server administrator or web hosting provider.
4. Click OK to connect

Goal
To synchronize (one way) local files with remote files and vice verse by matching names and content.

SmartFTP allows you to control the action taken when synchronizing files with matching names when using the Transfer Queue. By enabling the Integrity Check option (File exist action based on the comparison between hash values, under File Exist Queue), the destination file will be compared against the source file based on content using hash values vs. i.e. size, time, etc. If the content of the destination file is the same, the file is left unchanged. If the content of the destination file is different, the transferring file replaces the destination file. Otherwise, if the Integrity Check option is left unchecked the default File Exist Rules will be used. Though the Integrity Check option is recommended you can edit the File Exist Rules based on your needs. Also, not all servers support the Integrity Check option in which case one way synchronization has to be done using the File Exist Rules. For more information about the File Exist Rules please see the following Knowledge Base article:
KB: File Exist Rules

Synchronization Methods
Currently two synchronization methods are supported. To change the synchronization method, select the item(s) in the Transfer Queue. Then right-click on the selection and select Properties from the context menu. In the Properties dialog you can select the desired Synchronization method.

• One Way Synchronization (Default)
  All files/folders from the source will be transferred to the destination. No files will be deleted on the destination.
• One Way Synchronization with Delete
  All files/folders from the source will be transferred to the destination. Files/folders in the destination which do not exist in the source will be deleted (on the destination).

Example
The following example shows how to synchronize the contents of a local folder with the contents of a remote folder.

Preparation: Settings

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the SmartFTP Favorites window select the Favorite to be used. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under the Transfer option select File Exists. From the File Exist tab under File Exist Queue you can enable the Integrity Check by checking the option "File exist action based on the comparison between hash values" or edit the File Exist Rules for the selected Favorite.
4. If the Integrity Check is left unchecked, SmartFTP will use the default File Exist Rules for the synchronization.
5. From the Favorite Properties dialog menu (on the left side), under the Transfer option select Integrity. Check that the Transfer Integrity option is enabled. The Transfer Integrity is enabled by default as specified on the Default Favorite Settings.
6. Click on the OK button to save the changes.

Queue Files/Folder

1. Connect to the server by opening a new Remote Browser
2. Open a Local Browser. Menu: File > New Local Browser.
3. Select the files on the local folder that you wish to synchronize with the remote folder. Drag the files from the Local Browser and drop them into the remote folder in the Remote Browser.
4. The files/folders will be added to the Transfer Queue
5. To change the synchronization method right-click on the items in the Transfer Queue and select Properties from the context menu.
6. Start the Transfer Queue.

How To

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the Favorites window select the Favorite of interest. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under the Transfer option select Integrity. From the Integrity tab under Transfer Integrity you can enable the XCRC feature.

• Secure (SSL Explicit) connection to the remote server
• Client behind a NAT router.
• Control connection to port 21
• Passive (PASV) data connections are not working (e.g. incoming connections blocked on the server side or FTP server behind a NAT)

If the Clear Control Connection (CCC) setting is enabled, the FTP client connects to the server, negotiates a secure connection, authenticates (sends user and password) and reverts back to plaintext.

To change the control connection protection in SmartFTP go to the Favorite Properties. Then go to the FTP->Connection->SSL/TLS dialog and change the Control Connection option.

Technical Background
NAT routers automatically examine the PORT command sent through a control channel for un-secured control connections to the default FTP port (21) of the remote FTP server. This allows them to open an incoming port for the data connection, setup the routing/forwarding and rewrite the PORT IP with the external (WAN) IP address. If a secured connection (SSL) is made to a FTP server, the NAT router cannot interpret the data correctly as everything is encrypted. Therefore it cannot translate a PORT command and open the appropriate port for the expected incoming data connection. By sending a CCC command and further reverting back to plaintext the NAT router are once again able to translate the PORT commands.

Server Support
Most modern servers support this feature.

With SmartFTP

1. Connect to the server
2. In the Remote Browser (server window) select the folder for which you want to calculate the used space
3. Right-click on the select folder and select Properties from the context menu
4. Click on the Calculate button

With a script running on your server

Calculating the used disk space on a remote server requires all folders to be recursively enumerated. This is a very inefficient if it has to be done this way. The better solution is to do this calculation directly on the server. We have written two scripts you can use for this purpose:
PHP and ASP Script - DiskUsage.zip

Problem

Having problems uploading/downloading

Solutions

Change "Data Connection Mode"
If you are connecting through a favorite then change the data connection mode in the favorite item settings dialog. If you are using "Passive Mode (PASV)" change it to "Active Mode (PORT)" or vice versa. Refer to the following Knowledge Base article if you are unsure how to do this:
KB: How To switch between active and passive mode
To verify the data connection mode being used, take a look in the log view of the Remote Browser. If you see a "PORT x,x,x,x y,z" command in the log view, then "Active Mode (PORT)" is enabled, if you see a "PASV" command then the "Passive Mode (PASV)" is enabled.

SIZE file
550 Can't check for file existence
550 Requested action not taken

Cause

The SIZE command is sent by the FTP client for two reasons :

• The SIZE command is sent in an attempt to determine if a file with the same name exists on the remote server.
• The SIZE command is sent in an attempt to get the size of the remote file.

In this case the 550 code returned by the remote FTP server is for information purposes only and can be ignored.

Best Practices

• Enable "Keep File Time." For more information on how to do this, please refer to the following Knowledge Base article:
  KB: How To preserve the time on file downloads
• Prefer FTP servers with MDTM, SIZE and XCRC support.

There are two important cases:

A) Your password has already been changed on the server side and you want to update it in SmartFTP 

1. Click on Favorites - Edit Favorites from the menu
2. Locate your favorite. E.g. look in the Quick Connect folder
3. Select the favorite and right-click on it.
4. Select Properties from the context menu
5. Go to the General dialog and change the password
6. Click OK
7. Connect to your favorite

B) You can login to the FTP server but you want to change the password you use to login

Most FTP servers do not allow you to directly change the password through the FTP client. They typically offer a control panel where you can manually set a new password for your account. If this is not the case please contact your web hosting provider for assistance. Once the password has been changed on the server side please proceed with A above.

The System i (formerly known as iSeries, AS/400, and Application System/400) is a computer platform produced by IBM. System i uses two different name formats (See Reference 1). By default format 1 is enabled. If the user/client sends a CWD command starting with a / the server automatically switches to format 2. To go back to format 1 you have to send a SITE NAMEFMT 1 manually or by using the custom commands in SmartFTP.

Starting with SmartFTP v2.0 Build 996 Patch 41 new custom commands have been added to change the "File Naming Format" easily. See Menu: Commands -> Custom Commands -> AS/400 (iSeries).

• Download PortableSmartFTP.zip.
• Extract the .zip archive to a directory on your portable device. e.g. P:\SmartFTP.
• Copy all files (SmartFTP.exe, sfFTPLib.dll, sfFavorites.dll, sfTransferQueue.dll, sfFavoritesShellExtension.dll, sfFTPShellExtension.dll, sfShellTools.dll, etc) and folders (en-US) from the SmartFTP installation folder (%ProgramFiles%\SmartFTP Client) to the folder on the portable drive (e.g. P:\SmartFTP).
• To start SmartFTP run the PortableSmartFTP.exe from your portable drive (e.g. P:\SmartFTP\PortableSmartFTP.exe)

Limitations

• The portable wrapper must be run under administrative privileges 
• There may be functional limitations when using the portable wrapper.

Please contact us if your favorite free editor is missing.

sfFTPLib is not licensed.

• Install the latest version of SmartFTP from the Download page (your settings will not be lost).

• From the Microsoft KB 555374: 
  1. Open regedt32.exe and browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\SystemCertificates\TrustedPublisher
  2. Under TrustedPublisher look for Safer key and delete it.

If you get one of the following errors:
500 'MLSD': command not understood by proxy
451 Connect: No Port Specified

Solution

Disable the Use MLSD option found on the Favorite Properties Dialog.

How to:

1. Select Favorites > Edit Favorites from the SmartFTP menu. The Favorites window appears.
2. From the SmartFTP Favorites window select the Favorite to be used. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under FTP select Transfer. Under the MLSD you can click on the drop-down option and disable the Use of MLSD.
4. Click on the OK button to save the changes.

Goal
To exclude or include files or folders during transfer by setting Filters. SmartFTP allows you to set filters from the Properties dialog box and apply them to individual Favorites. You can then selectively transfer files or folders according to your particular needs.

How To

1. Select Favorites > Edit Favorites from the SmartFTP menu. The SmartFTP Favorites window appears.
2. From the SmartFTP Favorites window select the Favorite that you want to apply the filter to. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under the Transfer option select Filters. From the Filters tab under the Options list you can enable filtering for the selected Favorite.
4. Under the Filter list select Use Favorite Settings.
5. If you want to filter at the folder level, select Folder under the Scope option. If the filter matches a folder name, the entire contents of that folder are included or excluded along with the folder.
6. You can also filter at the file level by selecting File under the Scope option.
7. You can filter by file extensions by using WildChars, for example, *.pdf.
8. Important: If you want to traverse into/include the sub folders you have to the add the following filter: Type=Wildchar, Value=*, Scope=Folder

Problem
After a successful transfer, the uploaded files are yet not updated on the website

Solution

• Make sure you are uploading into the correct folder/directory on the FTP server. The correct folder/directory depends on how the FTP server is set up. You may want to consult your web hosting provider for clarification.
  Common FTP root locations are /htdocs, /www, /wwwroot or /http
• Refresh the web page you are looking at in your web browser (e.g. Internet Explorer). The page will refresh from your local cache.
• Hold the Ctrl key while you click on the Refresh button (Ctrl + F5 works as well). By using the Ctrl + Refresh or Ctrl + F5 command, you are forcing the page to refresh from the server bypassing the local cache
• At last contact your web hosting provider for further assistance

Goal
To maintain an active connection to a server

How To

1. Select Favorites > Edit Favorites from the SmartFTP menu. The SmartFTP Favorites window appears.
2. From the SmartFTP Favorites window select the Favorite for which you want to use the Keep Alive feature. Right click on the Favorite and select Properties. The Properties dialog appears.
3. Under the FTP > Connection option select Keep Alive. From the Keep Alive tab under the Options list select Use Favorite Settings.
4. You can enable the Keep Alive feature for the selected Favorite under the Settings list. Select this to automatically send commands at random to the FTP server to keep a connection open.
5. Choose the time interval SmartFTP will wait before sending a command to keep the connection alive.

Cause
The FTP server denies clients to restart/resume an interrupted transfer.

Solution
Enable restarts/resumes of uploads and downloads on the server side. You may need to contact the server administrator or the web hosting company to request this change.

Special Case: proftpd
By default proftpd denies clients to restart/resume interrupted uploads (AllowStoreRestart). But it allows clients to restart/resume interrupted downloads (AllowRetrieveRestart). This causes the REST command to appear in the FEAT reply and SmartFTP assumes that restart is supported. Thus SmartFTP tries to restart the transfer and fails because the FTP server doesn't allow it.

GnuPG
The GNU Privacy Guard (GnuPG or GPG) is a free software replacement for the PGP suite. While it doesn't offer all the features (e.g. PGP Disk) of commercial products it does file encryption with ease. For example the GPGee shell extension which is included in the GnuPG for Windows package can directly be accessed in the SmartFTP Local Browser to encrypt a file on the local computer.

Problem
The backup archive (.zip) cannot be restored with the Backup Tool.

Cause
The backup file is not recognized by the Backup Tool. For example it is not possible to restore a backup created with version 1.x in version 2.5.

Solution
Install the latest version of SmartFTP on the computer you want to make the backup. Then you can restore the backup file on the new computer. If you do not have access to the computer with the backup anymore you can extract the files from the backup archive manually.

Important: There was a bug with SmartFTP up to version 2.5.1006.44 which caused that backup files created with the client could not be restored with the Backup Tool.

Problem
The following error is displayed when starting SmartFTP:
The installed product does not match the installed source.

SmartFTP version 2.5 has been discontinued.

Please download the latest version of SmartFTP from here:
Download Latest Version

If you would like to use version 2.5 of SmartFTP please purchase a license for the latest version:
http://www.smartftp.com/buy.php
The license is good for version 2.5 and version 3.0.

Situation
You want to download large files in the background from one server but you still want to quickly edit a file on the same server.

Problem
When using only one favorite to do this the edit operation will have to wait until the large transfers are finished.

Solution I 

1. Create a copy of your existing favorite which already contains the username/password and host information to connect to a particular server. For example you can rename the copy to "My Favorite - Large Transfers".
2. Go to the favorite settings of the "My Favorite - Large Transfers" favorite. Then go to the Transfer -> Queue dialog. Set the Number of Workers to 1.
   Important: The setting need to be changed in the favorite settings and not in the global settings.
3. Connect to the "My Favorite - Large Transfers" favorite
4. Set the number of Workers in the Transfer Queue toolbar to a value greater than 1. For example to 2. You can also change this value in the global settings. To do this go to the menu: Tools -> Settings then go to the General -> Queue dialog.
5. Download all the larges files you want. They will automatically get added to the Transfer Queue.
   You will notice that the Transfer Queue will only use one worker for all the files you have just added, regardless of the number of workers global setting.
6. Connect to the other favorite which you use to do your normal tasks like editing a file.
7. Now edit any file you want and it gets immediately processed in the Transfer Queue.

Solution II
With this solution the Open / View / Print / Play operations are handled in the Remote Browser instead of the Transfer Queue and therefore reuse the current connection in the Remote Browser. This also means that the Remote Browser is blocked during the download.

1. Install the latest version from http://www.smartftp.com/download
2. Go to menu: Tools -> Settings. Then go to the General -> Navigation dialog.
3. Set the Open / View / Print / Play operation to Browser.
4. Click OK to apply the change

Problem
When using SmartFTP version 3.0 you experience problems uploading. In particular files do not get transferred or do not seem to show up on the server.

Solution
Please follow the steps below to solve your problem:

1. Download and install the latest version of SmartFTP from:
   http://www.smartftp.com/download
2. Take a look at the Upload Tutorial.
3. If the Transfer Queue (the window at the bottom) is not started yet (it means the blue play button is disabled) click on the blue play button to start it. By default the Transfer Queue is automatically started.
4. If the files are stuck in the Transfer Queue double click the first file and look at the log. You will find the reason the file is not transferring in the log. Please see the 2nd paragraph of the following article on how to get the log: KB: How to get the logs
