Networking, traceroute on linux
I get the following:
Is this telling me I can ping 10.14.10.10, but its actually more than 30 hops from me ???
Can be so, its my gateway. Am I misunderstanding something ?
-bash-3.2# ping 10.14.10.10

I fully agree with the first part,
but for the second part : how do you explain the ttl of 64 ?

64 bytes from 10.14.10.10: icmp_seq=1 ttl=64 time=0.209 ms
That is the OS default for all TCP traffic....
But for traceroute it is altered to equal 0 in the first iteration, then 1, then 2...so on and so forth...

yes I know , so suppose the target machine is linux.( which has default TTL 64) , and the ping reply has TTL=64 , then the target machine is only one hop away. no ?
No it is zero hops away, meaning it doesnt pass throughn a router, only switches. He is pinging a machine within his home network
