Hello,
In my organisation there are 3 server ip ranging 10.0.0.x1 ,10.0.0.x2, 10.0.0.x3. If i ping to them ping takes ttl as 128. I have my IP as 10.0.0.100. When i ping to x1 server i got ttl as 128 and if i ping to my adjecent pcs i got ttl as 64. why this is happening? All are on same 10.0.0. network. Also then i make my PC as Router with 2 NIC. and connect my neighbour pc with crossiver wire and assign it as a 192.168.1.200 and allow my PC to Forward traffic. Then i ping to 192.168.1.200 from 192.168.1.100(eth1 on my pc) and got ttl as 64 and viceversa. I observe same analysis while pinging to our proxy server from 192.168.1.200 to 10.0.0.x1 but with ttl 127.
All these observations are taken on RH 9 linux with proxy server having windows 2000 server.
I require further TTL explanation please help me
regards,
cranium

What would be really interesting is why you think it matters, but if you read the man page for ping (right near the end, "TTL details"), it tells you that it prints the TTL from the response packet. The reason you see different values is because the systems you are pinging set different TTL values on their packets. If your man page doesn't have this text, you can read it here.
