FTP stopped working on my server a couple of days ago. If I try to connect using an ftp client, I can't get connected. If I try to run FTP interactively from the command line, I get "connection closed by remote host" after I enter my username. I am running PROFTPD on RHE server. I have restarted PROFTPD and rebooted my server, with no luck. Any idea what could be causing this or where I can find the log file for FTP?
What is the error received when trying to connect with an FTP client?
Have you recently added any firewall rules to the server or setup any firewall hardware appliances? If you're being authenticated with the username/password but no directory listing shows up, disable passive FTP mode on your FTP client.
