dynipdrop

It's a IDS-receiver and written in C.

Sometimes I want to drop remote IP xx seconds, and Undrop it when timeout;

Sometimes my sniffer-server find a hack-action and I want to tell another server/server-group "Drop xxx.xxx.xxx.xxx IP xx seconds".

So I written this program -- dynipdrop("dynipdrop" daemon and "ipdrop_local" to send a drop-msg from localhost, and "ipdrop_udp" to send a drop-msg to another server(installed the dynipdrop daemon).

And I think: "Maybe I can make a client to drop the ssh-scan, like DenyHost(http://denyhost.sf.net)", so I write the "sshdprotector".

dynipdrop run on linux and need iptables, I use "portsentry(http://sourceforge.net/projects/sentrytools/" + "sshdprotect" + "dynipdrop" to protect my servers, and hope this software make some help to you.
