git with ssh key

 git with ssh key can only run with git URL, not http

One way is to set the URL to git

$ git remote set-url origin https://github.com/USERNAME/REPOSITORY.git

RSA key problem to github

I tried ssh -vT git@github.com and found out that it look for default key files. So, I renamed my RSA key files to the default name, and this solved the 'publickey declined' problem.

Apparently, the rsa key on my laptop was broken, not the public key on my workstation. This seems to explains why I cannot connect to github using ssh.

Trouble is: The public key and finger print are the same on my laptop and github profile.???
