yum install corkscrew
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).
