hijack a gre tunnel

you'll need a shell account on my box already to do this

there's a suid program named "hijack-gre-over-udp" that will

allow you to point the remote end of a gre over udp tunnel

to wherever it gets a packet from next.

I'm thinking of changing it so that this command runs from

a TCP port, and requires that the next packet it receives is from

the same IP that the TCP connection is made from...

yeah. I'll do that. but not right now I guess.
