Hiya I recently started (trying) to use sshit to filter the many brute force sshd attacks.
However, it has never worked on my box. FreeBSD 7.0 p1. This morning it would only give a message (without exiting) Could not create semaphore set: No space left on device at /usr/local/sbin/sshit line 322 Every time it gets stopped by CTRL-C it leaves the shared memory behind, allocated. I am going to reboot later and double the number of semaphores (in loader.conf). I am running hobbit which uses 8, leaving only 2 free. This may solve this issue, but I'd appreciate any ideas and experienced advice. A side issue is that sshit will only filter rapid fire attacks, but I am also seeing 'slow fire' attacks, where an IP is repeated every 2 or 3 hours, but there seem to be a network of attackers because the name sequence is kept up across many incoming IP's. Is there any script for countering these attacks? If not I'll write one I think. -- DA Fo rsyth Network Supervisor Principal Technical Officer -- Institute for Water Research http://www.ru.ac.za/institutes/iwr/ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
