Connecting to local ProFTPD takes a long time
I have a Gentoo system running the latest version of ProFTPd. When connecting to the FTP server from another system in my network it takes quite a long time (20 seconds or so) before I have to enter the username and the password. I tried different clients etc but that doesn't matter. Once I am connected, the speeds are superb.
If I do a local connect (so ftp localhost) on my Gentoo system, everything is fine and fast.
What could this problem be?
