Greetings, Oh wow! That's cool. I missed that somehow. The 'man' page doesn't mention the hash functions options. On the Cat 6500s you can log into the Sup and change the hash function so it's not just IP, but rather IP+Port. I've previously used this to balance the load across multiple

2005-08-25 Thread Gary D. Margiotta
Hello, Probably a stupid question, but I've not had much luck searching for the answers (probably because I'm not using the correct search terminology). Is there a way to bond multiple network cards together, so as to get a higher aggregate bandwith? And also, if it is possible, is it recomm

FreeBSD 5 ip_gre and netisr_enable=1

Hi, This problem exit in some old gre.c (not a part of official freebsd) to handle wccp packets. A carefully crafted packet can cause it to deplete kernel stack and casuing a panic. It can crash a 4.2 kernel with about 200-300 repeated ip+gre header. I believe the problem appears on FreeBSD
