Thanks for all the answers! I'v started making a script for doing this in bash (ye, not perl!). The script will first collect all the iptables-save from a couple of servers, sort out dublicates, sort out ips that is whitelistet (if any) and then dist the rules with ssh and public key and the ssh command= option and finally restart iptables around if the rules have changes (it makes and md5 sum of the fw rules and check if its changed..) Again, thanks! :=) -- Lars On 4/11/06, Hayes, Ian <Ian.Hayes () wynnlasvegas com> wrote:

The plan is to have (on one of the servers) a script that automaticly block ip adresses with iptables depending on different conditions. When that ip adress is blocked I want it to automaticly be blocked on another server to. One idea is to change the script that is adding the block rule to iptables to make it soo it can send the rule to the other server, but this is not an option, the iptables rules must be synced after the iptables rule have been added. Another idea is to get the iptables to use an sql database of some sort to load the rules, but I dont know how, and this whould be somehow ruining the whole thing of having a firewall if you make it dependent an sql server (i think).. But afterall, if this is possible this is option. Any ideas? Hope someone can help out..Iptables-save and restore, or you can go super-cool and use dsh Ian Hayes | Senior Systems Engineer Wynn Las Vegas 3131 South Las Vegas Blvd, Las Vegas, NV 89109 Ph (702) 770-3252 | Cell (702) 266-6002 Ian.hayes () wynnlasvegas com ------------------------------------------------------------------------- This List Sponsored by: Webroot Don't leave your confidential company and customer records un-protected.
