Github (SSH) via public WIFI, port 22 blocked

I'm currently on a public WIFI spot and I'm unable to use SSH (they probably blocked that port). However, I need that connection to do a git push.

➜ ssh -T git@github.com
ssh: connect to host github.com port 22: Connection refused

Is it possible to bypass this restriction by setting up a SSH tunnel via port 80 and tell github push to use that connection? How to do that? I'm on OSX (lion). This must be a common problem?

Try this:

$ vim ~/.ssh/config

Add

Host github.com
  Hostname ssh.github.com
  Port 443

The same works for Bitbucket:

Host bitbucket.org
  Hostname  altssh.bitbucket.org
  Port  443

In addition to configuring it with the ~/.ssh/config file, you can also simply include the port number in the remote URL you use. You just have to

1. use a proper URL like ssh://user@host:port/path instead of the user@host:path shorthand; and

2. prepend the ssh. subdomain to github.com.

For instance, instead of

git@github.com:cdbennett/python-gitlab.git

use

ssh://[email protected]:443/cdbennett/python-gitlab.git

For gitlab, following can be added:

Host gitlab.com
  Hostname altssh.gitlab.com
  User git
  Port 443

No need to modify the ~/.ssh/config. You can add another remote repository via git remote add ...

// github
git remote add ssh://[email protected]:443/repo/name.git

// gitlab
git remote add ssh://[email protected]:443/repo/name.git

VPN (ExpressVPN) worked for me on JetBlue

I find two ways

First

• tor + torify

After successfully Install and configure tor on system simply run this to check ssh use tor.

torify ssh -Tv [email protected]

Second

• tor + privoxy + corkscrew

First configure tor from fist step. Then install privoxy to convert tor SOCKS5 to HTTP proxy.

sudo apt install privoxy

Then install corkscrew

sudo apt install corkscrew

Place this config file in: ~/.ssh/config

host *
    ProxyCommand corkscrew 127.0.0.1 8118 %h %p

Or with ncat

Host gitlab.com
        User git
        ProxyCommand ncat --proxy 127.0.0.1:8118 %h %p

Also can use nc instead of ncat

    ProxyCommand nc --proxy 127.0.0.1:8118 %h %p

Now ssh can use configured proxy.

[Edit]

Simpler version

Use torify before ssh command.

torify ssh -Tv [email protected]

To works with Privoxy+Tor may need to change default configs. For me uncomment this line in /etc/privoxy/config

forward-socks5t   /               127.0.0.1:9050 .

ssh config

Host *
    ProxyCommand nc --proxy 127.0.0.1:8118 %h %p
