i'm having big trouble with my proftpd installation: the login is slow as hell, it takes about 10 seconds and more and that's to much for the default settings of most ftp clients. i'm using mysql and mod_sql as backend for the login.
i've already searched a bit and added the following to my proftpd configuration:
UseReverseDNS off IdentLookups off ServerIdent on “...”
but that did not help at all. mysql is already set to not make any DNS lookups.
at the moment i have no idea, what to try next -- do you have any?
thanks a lot!
