Is there a way to use a file containing a list of strings in a filter? Something similar to "grep -f FILE"? I would like to avoid the need to rebuild a (string1|string2|...|stringn) construct in the failregex each time the list is updated. My list currently has 80 entries; I expect it to continue to grow over time.
My use case is that I would like to match on exim4 deliveries to ":blackhole:". Unfortunately the delivery lines in the exim4 log file that show delivery to ":blackhole:" do not include the source IP address. It is straightforward for me to extract the list of usernames that are forwarded to ":blackhole:" from /etc/aliases, which brings me back to the leading paragraph. I would, of course, be pleased to receive suggestions of alternative approaches that would solve my problem. Thanks, K _______________________________________________ Fail2ban-users mailing list Fail2ban-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/fail2ban-users
