I was struggling to get this working in one of the server while starting ProFTPd service. Even re-installing it didn’t resolve the issue.
Following are the lines shown in log file:
– warning: unable to determine IP address of ‘example.com′
– error: no valid servers configured
– Fatal: error processing configuration file ‘/etc/proftpd.conf’
Finally I got it resolved and back on the track by adding Domain to IP resolution in hosts file at: /etc/hosts
Adding following lines resolved this issue:
126.96.36.199 blog muhammadattique.com
Then I tried to start ProFTPd service again, Wow.. this time it started.
