How do i restart the server?

Hey guys my clan server crashed!! and i dont know how to restart it!! how do i restart it by using smart ftp.

you don't. if the ftp service crashed, you won't be able to access the server with *any* ftp client anymore. you need to connect via ssh and restart the service from the command line.

guys, this is an ftp related forum. as such, we always mean ftp servers when just talking about a "server", and not any proprietary game server software like a dedicated half life server. half life has its own community which should be able to help you. this has really *nothing* to do with ftp anymore.
