On both machines im using Debian. Debian 5.
I can connect both passive as active on the one working machine and neither on the other.
Both servers connect to a third machine where mysql is installed.
The working machine doesn't show anything except succesfull logins. The other states
"pure-ftpd: pam_unix_auth(pure-ftpd:auth): authentication failure; logname= uid=0 euid=0 tty=pure-ftpd ruser=t3st rhost=hosted.by.myself.com"
A computer is almost human - except that it does not blame its mistakes on another computer.
