I have a very stable Ubuntu installation with ISPConfig3 and pure-ftpd. After reinstalling the package, it's not working anymore (all other things are). I enabled the logging and when I try to log in, the following is posted: Oct 25 20:23:49 server2 pure-ftpd: (?@myhost) [INFO] New connection from myhost Oct 25 20:23:49 server2 pure-ftpd: (?@myhost) [INFO] PAM_RHOST enabled. Getting the peer address Oct 25 20:23:55 server2 pure-ftpd: (?@myhost) [WARNING] Authentication failed for user [user_name] Oct 25 20:23:55 server2 pure-ftpd: (?@myhost) [INFO] Logout. In the FTP program I'm getting: Antwoord: 220---------- Welcome to Pure-FTPd [privsep] [TLS] ---------- Antwoord: 220-You are user number 1 of 50 allowed. Antwoord: 220-Local time is now 20:23. Server port: 21. Antwoord: 220-IPv6 connections are also welcome on this server. Antwoord: 220 You will be disconnected after 15 minutes of inactivity. Commando: USER user_name Antwoord: 331 User user_name OK. Password required Commando: PASS ******* Antwoord: 530 Login authentication failed I also changed password via ISPConfig and added new user. All didn't help. I also looked ad mysql.conf and that all seems right (at least the credentials). Can anyone point me in the right direction?
