How to push to heroku behind a proxy?

Question

I am using git behind a proxy server at my university. While trying to execute

git push heroku master

I get an error

ssh: c         


        

Answer 1

Heroku only supports git pushes over SSH (port 22) - it's likely that your university is preventing outbound port 22 access which causes your push to fail.

Answer 2

Corkscrew is a tool for tunneling SSH through HTTP proxies

Setting up Corkscrew with SSH/OpenSSH is very simple. Adding the following line to your ~/.ssh/config file will usually do the trick (replace proxy.example.com and 8080 with correct values):

ProxyCommand /usr/local/bin/corkscrew proxy.example.com 8080 %h %p
