Re: Access SSH server via HTTP proxy

Thanks for your response.
yes, I do have to enter the proxy hostname and port in my browser.
As i indicated earlier, no traffic is allowed except traffic go thru
the proxy (after filtering and inspect I guess)

Thanks

Hi,

I have learned that you can access ssh server via http proxy. But when
I set it up in PUTTY (under Connection -> Proxy tab) looks like the
HTTP proxy detects I am trying to connect to SSH server. Thus it throws
service not allowed exception (error 403).
But if I try to change the port # of ssh server setting for PUTTY from
22 to 80 it throws this exception:
503: service unavailable.

So I wonder if I change my SSH server port to 8080 for example, will it
work for me?

Thanks guys


In order to access the web from work, do you have to enter the proxy
server's info into your browser's configuration? If not you may be
hitting a firewall restriction and not a proxy server issue at all. If
this is the case you just need to run your ssh server on a port that is
not blocked by the firewall and configure putty to connect to it
directly on that non-standard port. A few that would likely work are 80
(http), 443 (https), 8080-8089 (typical proxy server port #'s).
