MODE Z will not enable even though server supports it.

This issue may not be a "bug" in smartFTP, but since i can't figure out why it won't enable, its a bug in my opinion.

I'm the author of CrushFTP...a full scale FTP server. I'm adding MODE Z support since FTP clients are finally supporting it well enough now. Plus no-one notified me that such an extension even existed...I just stumbled upon it. I've had zip support for years, just not with this official extension support.

Anyway, ehre is a log sample from a slient login from SmartFTP. Notice the FEAT replies that MODE Z is supported, but SmartFTP never bothers to change. I have SmartFTP set to "auto" for listings, downloads, and uploads.

What is the "trigger" event that will make SmartFTP issue the "MODE Z" command?

Feel free to email me directly as well. ben@crushftp.com

Thanks,

FYI, this was the current build of SmartFTP as downloaded from the Website today on Windows XP.

Hello ...

Since we are in contact I would recommend you to implement the "MLSD" feature. You can find more information in the RFC at:
http://www.ncftp.com/ncftp/doc/rfc3659.txt

XCRC, XMD5 and XSHA are other commands/features I consider as important.

At least now you can't blame anybody from not telling you

Regards,
-Mat

That was exactly it. Everything works perfectly now. CrushFTP 4.1 supports MODE Z with SmartFTP now.

Thanks!
