I have a machine with a cvs repository on it, behind a firewall and a
demand dialled modem. I have another machine out on the internet, to
which I connect with ssh.
machine A ----- machine B ---modem---internet ----- machine C
cvs repo firewall
I would like to be able to do cvs co/update etc on machine C during a ssh
session from A. I'm thinking that I can do this with a ssh tunnel of some
sort, but as machine C is on the open internet, I don't want to leave any
trace of what/where machine A is or any passwords. Nor do I want to have
to use su in order to achieve it.
The ways I can see of doing are:
1) Set CVS_RSH=ssh and get machine C to connect back. This has two
problems: a) I'd need to have the user on machine C's keys in an
authorized_keys file on A and, b) it won't get through the firewall.
2) Setup a ssh to forward the pserver port. However, I'd need to put a
password on machine C in order to get access to A.
3) Setup ssh to forward rsh. I feel this is worse than 2.
Is it possible to set CVS_RSH to some devious value, so that it uses the
basic ssh connection backwards?
