how to setup ispCP on ubuntu 8.04 LTS

[ephigenie]

Please take a look if proftpd uses the right config (the one modified from ispCP setup )
and if the Variables in your conf are substituted with the right values (especially username, password, mysql hostname shall match your setup)

If all right, try to connect to your db with the values in your db.
If all right, look into the corresponding log files for proftpd and search for errors/ failures. Try to login and see if something happens in your log.

post your results here.
