proftpd connection not possible

[Lirion]

Hello there,

unfortunately I'm in the current situation that I have to solve problems for a customer on a somehow messed-up system.

Please don't block this request by the version numbers only, said customer's IT service did not update the system for aeons now, but I hope for first instance I still can enable FTP connects, for this HAS TO BE done before migrating the whole system to some stable state.

Now, what is my problem?

The ispCP backend is somehow instable. I can't switch to any user anymore. So far, so good. What I want to do now is change the FTP passwords for the users. I tried this by doing this on the system itself (Debian), and after a restart of the proftpd I can't even reach the server. Error message is:

Connected to xxx.
421 Service not available, remote server has closed connection

However, I can edit the MySQL database now, I can edit the configs, I can do fairly anything - but I still don't know exactly how ispCP takes influence on the system configuration.

Any help?

Debug follows.

Debug #2: System information

OS: Debian 4.0 Etch (sic)
ispCP version: ispCP 1.0rc3 OMEGA (sic)
proFTP version: 1.3.0
MySQL version: 5.0.32-7etch10


And again, please don't blame me for those old versions - I want to help now and until now the customer didn't know sh** about properly caring for a web server. I just need help, if there is any in the current state... :/

And some further information: the system seems to have been installed via some alpha release back in the old days, and seems to have been updated to this rc3 release ... several weeks ago.

Also, I changed the mysql root password since nobody knew this, and updated the ispCP configuration to the new password by deleting it from the config file and calling the ./engine/ispcp-db-password routine thereafter. The backend works, however, I still can't switch users.
