FreeBSD's default ttl, I believe, is 64, Cisco's is probably 255. As long as the number of hops neccessary to get to a certain computer is never more than 64, there's nothing wrong with it. The highest I've seen is about 30 and the Internet is going to have to grow a bit, I think, before it's an issue. > > Thank you > > 64 bytes from 212.223.x.193: icmp_seq=1151 ttl=251 > time=100 ms > 64 bytes from 212.223.x.193: icmp_seq=1152 ttl=251 > time=103 ms > 64 bytes from 212.223.x.193: icmp_seq=1153 ttl=251 > time=104 ms > 64 bytes from 212.223.x.193: icmp_seq=1154 ttl=251 > time=106 ms > > 64 bytes from 212.x.254.4: icmp_seq=1182 ttl=58 > time=105 ms > 64 bytes from 212.x.254.4: icmp_seq=1183 ttl=58 > time=105 ms > 64 bytes from 212.x.254.4: icmp_seq=1184 ttl=58 > time=104 ms > 64 bytes from 212.x.254.4: icmp_seq=1185 ttl=58 > time=108 ms > > __________________________________________________ > Do You Yahoo!? > Tired of spam?
