No, that is handled by code before this which sends the appropriate ICMP message to the peer. >Shouldn't we log such occurences? I actually think logging stuff like this on a host is a waste since legitimate utilities like traceroute can generate LSR packets. Logging this actually makes one vulnerable to syslogd attacks by simply sending a flood of LSR packets to the host. If people really want to log these sorts of failures then they should configure their firewall appropriately. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
