FTP Access Not Working

[lukemccoy]

I've been running Plesk 8.3.1 for a couple months with no problems and now I can't FTP into any of the domains on it. Any ideas?

Make sure that FTP server is functioning and port 21 is opened.
# nmap -p21 -P0 server_name
# telnet server_name 21
# netstat -nap | grep 21

Also, check following KBs:

Make sure your IP is not blocked due to a failed BFD, ossec Shun, etc.
