Hi, i get msg in syslog every 5 minutes like: Code: pure-ftpd: (?@::1) [INFO] New connection from ::1 dovecot: pop3-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=::1, lip=::1, secured, session=<placeholder> dovecot: imap-login: Disconnected (disconnected before auth was ready, waited 0 secs): user=<>, rip=::1, lip=::1, secured, session=<placeholder> postfix/smtpd[25005]: connect from localhost[::1] Am i right that this is the service up check from ispconfig? Is it possible to change that to 127.0.01 (IPv4) ? I ask because i get errors in fail2ban log: Code: fail2ban.filter : WARNING Unable to find a corresponding IP address for ::1: [Errno -9] Address family for hostname not supported i am a little bit nerdy and i want to get clean logfiles
The check is on localhost, so it is a ipv4 check. Just most service stoday report this as ::1. If you want to see a different IP for localhost in the log file, then change your /etc/hosts file and disable ipv6 at all. Fail2ban does not support ipv6 yet.
