Lorsque j'interroge directement la regex, j'obtiens ceci :
Root rayleigh:[/etc/fail2ban/filter.d] > fail2ban-client get courier-tls
failregex
The following regular expression are defined:
`- [0]:
^.*ip=\[(?:(?:::f{4,6}:)?(?P<ip4>(?:\d{1,3}\.){3}\d{1,3})|\[?(?P<ip6>(?:[0-9a-fA-F]{1,4}::?|::){1,7}(?:[0-9a-fA-F]{1,4}|(?<=:):))\]?|(?P<dns>[\w\-.^_]*\w))\],
An unexpected TLS packet was received.$
J'avoue que je ne sais pas interpréter.
Bien cordialement,
JKB
