This is an issue that we recently ran into at work and I wanted to mention this since 5.0 isn't released yet. I don't know if FreeBSD has addressed this or not but thought it should be mentioned just in case. We've discovered that in many *nix OS's the TCP stack sets the default TTL for packets to 30. Apparently, IBM (AIX) had not and our research showed that most of the other *nix OS's hadn't either. With the increasing complexity of the internet, this is often a problem for those who have large internal networks and/or live in Australia. 30 hops often isn't enough to make to the core DNS. It probably ought to be extended to something more realistic. The other numbers that I've seen used 64, 128, and 256. Thanks, Ms. Jimi Thompson Those who are too smart to engage in politics are punished by being governed by those who are dumber. - Plato To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
