Why are you replacing known spammers with these "banned" strings ? This forbids anti-spam filters & programs to do their jobs properly.

man_in_shack banned me during a casual conversation where i was explaining my dual x server wine setup, saying I was contradicting myself. I obviously wasn't trying to contradict myself, if I did, and I don't see how this is ban-worthy under any circumstance.

Hi Pete, I did wonder that myself.

I have fail2ban on my mail server monitoring Dovecot and Exim. I have noticed that it has stopped banning IP's. I have seen in /var/log/fail2ban.log: 2020-04-07 09:42:05,875 fail2ban.filter [16138]: INFO [dovecot] Found 77.40.61.224 - 2020-04-07 09:42:05 2020-04-07 09:42:06,408 fail2ban.actions [16138]: NOTICE [dovecot] Ban 77.40.61.224 2020-04-07 09:42:06,981

Is anyone using asterisk with fail2ban? I have it working except it takes way more break-in attempts than what is set in "maxretry" in jail.conf For example, I get an email saying: "The IP 199.204.45.19 has just been banned by Fail2Ban after 181 attempts against ASTERISK." when "maxretry = 5" in jail.conf Perhaps someone else is experiencing this or has resolved it, thank you in advance for your time. -------------- next part -------------- An HTML attachment was scrubbed...

Is there a functiaon to take the IP address of person who submits to a form example: <input id="user_ip" name="user[ip]" type="hidden" value="<%= some_ip_call %>" /> -- Posted via http://www.ruby-forum.com/.

I'm looking for some beta testers to provide feedback on an Asterisk intrusion detection & prevention program we're releasing soon. As a quick overview, the program provides: - banning based on geographic location of source IP (Continent, country, region, city, etc) - detection and banning based on channels in use by a user - detection and banning based on rate of dialing - detection

Hello, I have read and seen many options for additions to Iptables as a firewall and security system. All seem to react to logs and not to incoming packets (as far as I have seen) I am interested in doing a number of security ideas to the firewall, iptables, on my webserver. If you have a program you would suggest or believe iptables is the proper solution, please feel free to post that. Here

So I have been reading the ssh attack thread and finally want to ask about something. I doubt there is a program like this, but I would love to have a program that listens at common ports that I do not use at all...and only allow that program to listen to it, especially the usual ssh port (using a different one for real ssh)... That program would then, upon receiving a 'sniff' or
