DenyHosts is working really well with SSH now, blocking attacks almost
immediately. But I still have a problem with attacks via proftpd, they don't
seem to trigger the rule. Using information I got from this list, I have the
following rules:
SSHD_FORMAT_REGEX=.* (sshd.*:|\[sshd\]|proftpd) (?P<message>.*)
USERDEF_FAILED_ENTRY_REGEX=.*proftpd.* USER (?P<user>.*): no such user found
from .* \[(::ffff:)?(?P<host>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})\] to .*:21
USERDEF_FAILED_ENTRY_REGEX=Invalid user (?P<user>.*) .*from (::ffff:)?
(?P<host>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})
The third rule works fine but the second seems to be ignored. The proftpd logs
have records like:
Apr 12 05:40:55 opal proftpd[7543]: opal.binro.org (60.28.246.175
[60.28.246.175]) - USER Administrator: no such user found from 60.28.246.175
[60.28.246.175] to 192.168.1.2:21
When I insert the rule and the record into kodos, i get a match and <user> and
<host> are correctly set. So what am I doing wrong?
TIA
