When you make a connection to your server, does it take forever? If so then you might be experiencing ProFTPd’s attempt at doing a reverse DNS lookup.
To remedy this problem, we are going to add a few lines to the proftpd configuration file for the Ensim webppliance.
Using your favourite text editor–I use PICO here as most beginner level people use it–to modify the following file:
then simply add the following lines:
ServerIdent on "FTP Server ready."
Note: the UseReverseDNS off does NOT work within the <Global></Global> tag!
Now restart proFTPd
Then try to log into your server again. A connection should be made almost instantly.
