man corkscrew
You have to tunnel ssh over https to get through your proxy. Your
proxy may also require that your ssh+https destination be listening on
port 443, meaning you'll have to have your target system run sshd and
listen on port 443 (in addition to listening on port 22).
FWIW... I've been able to make wget work by specifying the environment variable and specifying --proxy-password= and --proxy-user= that works fine.
My next step was to see if I could get SSH to go through...
On a Windows box, I use PuTTY and specify the userid/password and the proxy address/port... works fine.
So my next step was to see if I could get SSH from Linux to go through the same proxy... but I don't know how/where to specify the proxy password/user etc, so it fails. Along comes "corkscrew"... I'll check that out.
There s a whole bunch o' option in ssh_config etc, I'm surprised there isn't a "convenient" way to do this.
Once I get ssh working through the roxy, I should be able to get sftp riding on top of it...
Thanks
