how to solve proftpd very slow connection?

  • 772

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!

    here's the answer for my problem:

    apparently the SQLAuthenticate directive was the problem. it was set to:

    SQLAuthenticate users userset

    i've changed this to

    SQLAuthenticate users

    now authentication is fast as hell.

    i've found a howto on the proftpd site, that explains why this configuration may cause problems:
