Wouldn't it be simpler and safer to just tweak the value in /proc/sys/net/ipv4/ip_default_ttl on each host according to its hop distance from the router? -- Ian Zimmerman gpg public key: 1024D/C6FF61AD fingerprint: 66DC D68F 5C1B 4D71 2EE5 BD03 8A00 786C C6FF 61AD http://www.gravatar.com/avatar/c66875cda51109f76c6312f4d4743d1e.png Rule 420: All persons more than eight miles high to leave the court.
