I have set up a Squid HTTP Proxy (in centOS) and intended to use it also for ssh connections.
Managed to configure putty (in a windows client) to use this proxy while connecting by ssh. Confirmed in the "target host" that the ssh connection was coming from Proxy server ip instead of the windows client IP.
targethost: 22 for ssh
proxyserv: 3128 for proxy (along with proxy credentials)
I'm now having problems connecting to the "target host" using Ubuntu and the same proxy server.
I have tried the following:
me@mycomp:~$ connect-proxy -H test@proxyserv:3128 targethost 22 Enter proxy authentication password for test@proxyserv: SSH-2.0-OpenSSH_6.2p2 Ubuntu-6
It hangs in last line, expecting some input. All attempts resulted in a "Protocol mismatch." error.
Putty successfully connects to the http proxy and sends credentials, showing me ssh login right away. - How to do (with commands in Ubuntu) the same putty does? - Is there any other way than connect-proxy command to do this?
Edit: Also tried the following with same result ("Protocol mismatch")
me@mycomp:~$ connect-proxy -H test@proxyserv:3128 targethost 22 ssh -l myshel_login
Thanks in advance
Edit: Solution details (thanks to NickW pointing the right way)
installed corkscrew and added to ssh_config
Host targethost ProxyCommand corkscrew proxyserv 3128 %h %p /etc/ssh/proxypass
created proxypass file
Restarted ssh and used a simple ssh command
(ssh password was asked as usual)
