Question
problem with regex in Fail2ban
Bonjour,
I try to enter a new jail for my fail2ban, but I’m not really good in regex.
My line to analyse is :
2017/06/30 06:15:19 [info] 2144#0: 257197 upstream sent invalid response: “NO AUTHENTICATE failed” while reading response from upstream, client: 59.61.79.82:33407, server: 0.0.0.0:993
and I try with
failregex = . upstream sent invalid response: ’.’ \client: ’<HOST>’\
and the error is
ERROR Unable to compile regular expression ’. upstream sent invalid response: ’.’ \client: ’(?:::f{4,6}:)?(?P<host>[\w-.^_]\w)’'
I try to change a part, to find a good way… but nothing good, and all the time this error.
Thanks for your help.
