Hi all,
I wonder, how I can change Time To Live field for icmp packet in Redhat 7.1, kernel 2.4.2-2? I looked up in /proc/sys/net/ipv4 and did find this field in there.
There should be a way to change TTL. If it's in header file, in which one?
Thank you all :p (11 Replies)

Hi all,
I'm having some trouble identifying what route is being used to talk to a target host. I can figure it out by looking at the routing tables but I want to automate this and don't much feel like scripting the network mask logic when I'd think there'd be a way to have the OS do it for me....
