ProFTPd Problems [RESOLVED]

[Haeber]

I've read a dozen of threads about proftpd problems, but no one had helped to find the solution.

Problems:
proftp seems to be down, no connections are possible, but the daemon runs

I use debian.etch.

netstat -tulpen | grep :21

Code:

proftpd -n -d 5

Maybe it has something to do with this

Code:

domain-xxx.tld - Failed binding to 0.0.0.0, port 21: Address already in use

But I don't know what to do to solve this problem.

Any hints?
