How about logging into B and then ssh'ing into C? Oh wait....
I'm assuming Box A is the putty box. Unless I'm an idiot, you'll have
to configure box B to do some work. You could set up a dedicated port
on B, say 8022, that automatically forwards requests on 8022 to
machine C's 22.
With iptables on B, you could do
B is 128.135.97.130
C is 128.135.100.100
/sbin/iptables -t nat -A PREROUTING -d 128.135.97.130 -p TCP --dport 8022 -j DNAT --to
128.135.100.100:22
Then you just have to putty from A to B on port 8022.
Or is B the putty box? Then you'll need something like:
