ssh connection timed out

问题

I am not able to ssh in git to github or bitbucket or gitlab.
I typically have the following error message: how can I avoid it?

========== output ============

ssh -T git@github.com -i ~/.ssh/id_rsa -v
OpenSSH_7.2p2 Ubuntu-4ubuntu2.2, OpenSSL 1.0.2g  1 Mar 2016

回答1:

The ISP has Blocked the Port 22. Solved !

回答2:

Kill the SSH process and restart it. It has solved me similar issues. I have found that multiple instances of SSH, in that case you have to kill them all.

回答3:

This error message is typical when

the remote ssh daemon is not running (which is not the case here regarding GitHub, BitBucket or GitLab)
the local port 22 is blocked for outgoing connection (which is generally the case when working in enterprise: only http(s) is open, not ssh)

The OP confirms the ISP has blocked port 22.

See if you can use an https url instead:

cd /path/to/my/local/repo
git remote set-url origin https://github.com/<user>/<repo>

Note that with trystack, you might need to follow this gist

Click the Security Groups tab, click Edit Rules, and add a couple rules:

imcp, from port: -1, to port: -1, cidr: 0.0.0.0/0
tcp, from port: 22, to port: 22, cidr: your.ip.address.here/32
