The order is the following:
A(ssh client) - C(http proxy server) - <Internet> - B(ssh server with static
IP)
Now A can't access the Internet. I can only run a browser on that machine
which includes the details from C and only then I can surf/have access to
the Internet only on ports 80 and 443!
As a result ssh from A to B doesn't work.
If I use putty on A and define the details of C in the putty proxy dialog
box, I can open a ssh session to B.
So the question is, how does this action of putty gets translated into an
ssh command? Which flag should I use from the ssh command line in order to
achieve the same result?
Thanks
Tony
