SSH no match found for remote protocol

messyman92 · 2015-05-28 20:00:16

I have been trying to push code to github via SSH, but every query I attempt hangs on the debug output `debug1: expecting SSH2_MSG_KEX_ECDH_REPLY`. I upgraded all my packages, created new ssh keys, and restarted sshd. Finally, I attempted the same queries (cloning, pushing, and even just an ssh -T) with bitbucket via SSH, and they all worked fine.

I've been trying to figure out why there is a difference between the two remote servers, so I diffed the output of ssh -T -vvv for both endpoints:

This is my ~/.ssh/config

Host bitbucket.org
    IdentityFile ~/.ssh/id_rsa
Host github.com
    IdentityFile ~/.ssh/id_rsa

Below is the output of ssh -T -vvv git@bitbucket.org

Any help would be greatly appreciated!

First, your config file is redundant, your key names are default names and no need to explicitly state them.

Second, can you post the exact *git* command you're trying to run? Did you add your SSH keys to your account? Are you pushing to a repo you have write permissions to?

messyman92 · 2015-05-29 11:51:37

@yuvadm ah, ok, that makes sense about the redundant config.

I'm running `git clone git@github.com:[username]/[repo].git` and `git push`. Local git commands work fine (creating branches, commits, etc). I am pushing to repos which I have access to, and I have added SSH keys to github and bitbucket using the same procedure. bitbucket worked, but github did not. In addition, I have in the past set up git over SSH on other machines, but never Arch.

In addition, I actually cannot push to github over https either:

This is definitely not an SSH error. I'd contact Github support.
