Most systems have 64 as default TTL, otherwise you're right. There are two "variants" of "Time to live exceeded". One is where the there are more hops to the target than the TTL set in the packet. This is known as "Time to live exceeded in transit". The other is if you're sending packets larger than the networks MTU and one part of the packet gets lost on the way. In this case you get a "Packet reassembly time exceeded". Both usually show up as "Time to live exceeded" by most system pings, as that's the "icmp type" (while the "icmp code", a different field in the icmp packet header, shows the variant). -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 ------------------------------------------------------------------------- Take Surveys.
