Correction: this happens only when going through the NAt code. I just tested and only time when it crashes is when one of the ends is in NAT ( i haven tested with both endss in NAT but thats rare to find anyways ) so to resume: kernel 2.2.10 ip utility ipchains one of the networks is NAT-ed ping -R a NAT ed ip from a real ip ( it has to go through the fw ) or ping -R a real ip from a NATed one fw has to be below hop 9 on this road otherwise it doesnt work. Result: complete kernel panic my ip nat rules are rather simple . so i belive anyone should be able to reproduce the problem. comments ? fixes ? -----Original Message----- From: Andrej Todosic [mailto:atodosic () ubisoft qc ca] Sent: Thursday, July 22, 1999 10:04 AM To: linux-kernel () vger rutgers edu Subject: ping -R causes kernel panic on a forwarding machine ( 2.2.5 and 2 .2.10) hello , i belive this is an old problem since this is not the first time i heard about it. ping ing with ping -R from through a firewall machine make the firewall go into kernel panic tried to kill idle task not syncing etc. etc. does anyone know a fix for the problem ? or a set of rules that will fix the problem ? i believe ping -R works only on about nine hops... what bothers me is that nine hops can be a lot of subnets :( Thanks for any help - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo () vger rutgers edu Please read the FAQ at http://www.tux.org/lkml/
