If you want afctl to manage unbans, set the actionban -t value to whatever you want the bantime to be, and clear the actionunban. If you want fail2ban to manage host unbans, set the actionban -t value to a value (in minutes) that is longer than the bantime value in nf (which is in seconds, so don't get confused).

# Fail2Ban configuration file for using afctl on Mac OS X Server 10.5Р В РІР‚СњР В РІР‚С›ctionban = /usr/libexec/afctl -a -t 2880 Call it nf and give it the following contents: Using afctl requires that you create a new file in the action.d directory.

Instead of using ipfw directly, you may wish to use the built-in afctl function, which handles all the ipfw junk for you. If you have a large number of banned addresses you may want to consider permanently banning some of them. ( Note: This method works until the counter reaches 1000 at witch time wanted rules may be deleted. If you still need to specify your server's IP address just leave off the so it blocks all the traffic. By changing to your-private-addy-here to to any in the ipfw add rule the firewall will block all bad traffic on this server, not just a specific port. Some attackers will cycle through the ports while using the same IP address. When it is time to unban an address, only the one rule is removed thus preserving the other banned addresses. This will search and use the first available rule number starting at 150. This is not desirable since any of the addresses added between the first ban and it's corresponding unban will now be allowed by the firewall and only logged as already banned by fail2ban (until their ban time is up or fail2ban is reloaded).Р В РІР‚СњР В РІР‚С› solution to this problem is to use the following: When the unban command is issued for the first blocked address it will remove the entire rule set with that number (in the above case rules 200 and 201) including any addresses that were banned after the first one. While the above actionban does block unwanted addresses from specific ports it suffers from defining all the banned address on a single rule number with a specific port. This should be done whether or note you have two IP addresses) Further enhancement ( Note: I also added rule numbers 200 & 201 so that they'd be higher up in the IPFW food chain.

(just make sure you've got defined in /etc/fail2ban/action.d/nf.) If you only have one IP address, you could have left the tag in place Obviously, you'll want to replace your specific IP addresses in the dummy placeholders above. Ipfw add 201 deny tcp from to your-private-addy-here Sudo emacs /etc/fail2ban/action.d/nfР В РІР‚СњР В РІР‚С›ctionban = ipfw add 200 deny tcp from to your-public-addy-here I have two ethernet cards (one public-facing, the other private),Р В РІР‚СњР В РІР‚С›nd I want to lock down both avenues when needed, We need to make a couple of changes in how fail2ban deals with adding rules. Make a little change in the ipfw actions if you have two IP addresses By adding *.info /var/log/ssh_info.log to /etc/nf you can gather IP-address and connection attempts from this file instead. However, if you want to detect failed attempts on for example a ssh-daemon running on another port only allowing rsa-authentication (useful if you want to port forward through your NAT-router), some extra tweaking is required. ( Note! In /var/log/secure.log all events related to keyboard-interactive logins can be found. In the section marked, you'll want to make it look like so: You can read all about this on the fail2ban wiki. Here's where you need to tell the program what you want to do. Make a spot for the log file sudo touch /var/log/fail2ban.log 5.
