Hi have ProFTPD runningon a brand new CentOS 5.8 server with Plesk, and its behaviour is inconsistent at best. I tried to transfer a directory from my PC, and every time I get a transfer failed on a random file. It's never the same one that fails, it just fails. Sometimes it's a .gif, sometimes it's a .css, sometimes it's a JPG. Of several hundred files, a dozen is always failing for no apparent reason.
The error that I get is the following:
COMMAND:> [27/11/2012 11:43:52] STOR main_border.gif [27/11/2012 11:43:53] 500 Invalid command: try being more creative ERROR:> [27/11/2012 11:43:53] Syntax error: command unrecognized.
The above is just an example, the "command unrecognized" occurs with LIST and other commands as well.
Here's the ProFTPD configuration, just in case:
ServerName "ProFTPD" #ServerType standalone ServerType inetd DefaultServer on <Global> DefaultRoot ~ psacln AllowOverwrite on </Global> DefaultTransferMode binary UseFtpUsers on TimesGMT off SetEnv TZ :/etc/localtime Port 21 Umask 022 MaxInstances 30 ScoreboardFile /var/run/proftpd/scoreboard TransferLog /usr/local/psa/var/log/xferlog #Change default group for new files and directories in vhosts dir to psacln <Directory /var/www/vhosts> GroupOwner psacln </Directory> # Enable PAM authentication AuthPAM on AuthPAMConfig proftpd IdentLookups off UseReverseDNS off AuthGroupFile /etc/group Include /etc/proftpd.include
Note: file /etc/proftpd.include is blank.
The above is the default configuration set by Plesk 11. I don't know much of why is that way, my knowledge of Linux System Administration is very basic and the one of ProFTPD is a complete zero.
Thanks in advance for the help.
Issue experienced with CuteFTP and FileZilla.
Replaced ProFTPd with PureFTPd, issue persists. Sometimes I get "command unrecognized", sometimes "failed to establish data connection". I'm starting to think that it could be a network issue, but I have completely zero knowledge of networking.
