I just started using 'fail2ban" and have not figured out how to create a custom filter.
I am running Postfix-3.0.1 on a FreeBSD 10.1 system. My mail-log is filling up with entries like this: Jun 19 06:29:40 scorpio postfix/smtpd[45535]: warning: hostname abts-mum-static-025.109.170.122.airtelbroadband.in does not resolve to address 122.170.109.25: hostname nor servname provided, or not known That is all on one line, although it is shown wrapped here. "fail2ban" is not catching this. I need to create a rule that would catch "hostname nor servname provided, or not known" or ""address <IP>: hostname nor servname provided, or not known" for it but I am not sure exactly how. I would appreciate it if someone could assist me. Thanks! -- Carmel ------------------------------------------------------------------------------ _______________________________________________ Fail2ban-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/fail2ban-users
