Is it possible to tunnel ICMP over TCP?
- by Robert Atkins
I don't want to tunnel TCP over ICMP (as ptunnel does), I want to go the other way around.
I'm in the situation where I have TCP (HTTP) connectivity to a machine but an internal firewall over which I have no control is swallowing pings. The monitoring software I'm using appears to determine connectivity by attempting to send a ping before it tries to just connect to the web service on the target machine. It's failing this ping test and giving up.
I believe if I could fool my monitoring software into thinking pings were getting through, it would then connect to the web service and be on its merry way. Anyone know how I can do this?
I have SSH and root access on the destination machine.
