A moving target is always tougher to hack...
Looks like I have been getting a FTP BF attack on my linux router hanging off of a cable modem. I am looking for suggestions on how I could continually get NEW ip addresses so I am not always sitting on the same IP...
I know a DHCP lease attempts to renew @ 50% the lease period, but only expires at 100%, and unfortunately even if I drop it on my client, the DHCP server will keep it registered... So, could I set my firewall to not allow DHCP traffic, then have a cron job kick in every 24hrs and 5 mins to modify the firewall ruleset, get me a nice new IP and lock the system back down? I assume the new IP could then be sent to my e-mail address so I could still access it as needed.... There must be an easier way that won't cause downtime. Suggestions??? |
First thing you have to determine if you have actaully been?
"cracked" or not? If you have then the best soluion is rebuild the server? Go to http://freshmeat.net and search for "root kit". Have you consider turning ftp? |
How about running OpenBSD? heh
