ssh with ISA Server problems


another poltergeist with our fantastic ISA Server and my centOS 5.8
I'd got configured and working the http_proxy, ftp_proxy variables and yum with our ISA Server, but now I need to use ssh and I get next error
Quote:
Proxy could not open connnection to db.XXX.YY: Proxy Error ( The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. )
ssh_exchange_identification: Connection closed by remote host
I'm talking with one of our network admin and he said me that now I've got the browsing by routing instead proxy, but I don't know how, unsetting the config of http_proxy, ftp_proxy and yum to not usin the proxy, I'm still having the same error and in the firewall we have petitions http to the proxy (I supose that it's asking a SSL request via http on port 22 instead 443 that is default for it).
Do you know how can I unset all setups of the proxy?

thanks a lot

well note that this is *nothing* to do with Linux whatsoever, this is about a Microsoft Proxy configuration and nothing else.

unless you change your SSH server to use port 443, you'd want to add an additional SSL capable port to ISA, i.e. one to which it will permit the HTTP CONNECT method.

I mean that now with a fresh install of centOS with no proxy configuration, the ssh connection didn't say anything about ISA Server, therefore in the old installation there would be any config file where the system has the config of the proxy server.

there's probably a ProxyCommand listed in ~/.ssh/ssh_config etc.

that's correct!!!!!!!!!!!
Now I need to wait to our 'fabolous' ISP to open ssh port by routing or accept SSL over HTTP in port 22.
Thanks a lot!!
