SSH over HTTP Proxy

story

nc -X connect is the popular way to communicate with SSH over proxy. However, it's broken when your client is MacOS.

solution

Install corkscrew

brew install corkscrew

SSH now:

ssh -4 \
  -o "ProxyCommand corkscrew ip.http.proxy port-http-proxy %h %p" \
  user@ip-machine-in-other-network

.i.e: in following example my HTTP_PROXY is 192.168.1.15:3128. And i want to login into 10.11.6.23

ssh -4 \
  -o "ProxyCommand corkscrew 192.168.1.15 3128 %h %p" \
  user@10.11.6.23

Note : -4 is to force ipv4 over other options (ipv6)
