It depends who you ping--maybe you're trying to reach a different host than you were with your last tests. BSD still sets the ttl to 255, I think, but if anything changed, perhaps FreeBSD has changed this default, but it's not in ping(8). Ping localhost and observe. Other systems may set it to different values. Some just don't change it--in this case you may see something "near" 255, depending on the amount of hops. The ttl values you see on a ping are taken from the return packet, so ping(8) itself has precious little to do with it. - Ryan > Thanks, > > Mario Doria > > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message > -- Ryan Thompson <ryan@sasknow.com> Network Administrator, Accounts SaskNow Technologies - http://www.sasknow.com #106-380 3120 8th St E - Saskatoon, SK - S7H 0W2 Tel: 306-664-3600 Fax: 306-664-1161 Saskatoon Toll-Free: 877-727-5669 (877-SASKNOW) North America To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
