Hi all, I have 2 CentOS 3.5 boxes & i do backups on the LAN Recently, I always get FTP timout error with large files "700 MB and more" .
i tried to log and do manual backup with FTP command and i also got the same result "FTP timeout"
i tried to google and i did # modprobe ip_conntrack_ftp but still get the same timeout message
Any one can help???

'man ftpd' at a shell prompt should point you to the ftpd configuration file where that timeout can be reset. Might be 'wsftpd' or some other name, try 'apropos ftp' at a shell prompt to get a list of available man entries on ftp/ftpd/etc. YMMV, HTH, & all that :-).
One of the servers is vsftpd & the other is pure-ftpd if i logged to server running vsftpd and tried to download any file, i can do that without problems regardless the size of the file. But if i logged to the server running pure-ftpd & tried to upload the same file, i get the time out message "Note here: The timeout always happens after the file completely uploaded, the ftp client hangs then gives the timeout message "
Also, If i logged to the server running pure-ftpd, i can use ftp command to download any file from vsftpd server but i can't upload the same file back to the server if this file size is big
Do you think that i should edit the configuration file for pure-ftd or vsftpd? If yes, Which parameter i should change
Thank you for your concern.

This sounds to me like a proxy/firewall problem, not an FTP configuration problem. My money says that the pure-ftpd box is behind a proxy/firewall that is checking to make sure that your ftp session is alive and at some point it says "no, I don't think it is" and it starts dropping packets. I only say that because I've seen the same problem and it turned out to be firewall config.
Maybe you could create an ssh tunnel for your ftp send send it over that and see if you get any difference.

I am not familiar with the vaguaries of vsftpd or pure-ftpd, however the man pages on those services *should* have the info you need. If you are getting the time-out from the vsftpd server (upload or download), that is the one you need to tinker with.
