ssh config for multiple bitbucket accounts - Simple example, but getting 'remote end hung up unexpectedly'

Question

Suppose my bitbucket user name is "jon" and I have some personal projects at https://bitbucket.org/jon.

Suppose I then join a development team that has a bitbucket account called "devteam" which can be found at https://bitbucket.org/devteam

Then suppose I am setting up a new machine. I generate an ssh key pair, id_rsa and id_rsa.pub which are in ~/.ssh. Then my dev team leader adds my id_rsa.pub public key to the devteam account on bitbucket. Now I can clone the projects from the devteam account and get to work.

Next I want to interact with my own jon account. However, I cannot add the id_rsa.pub key to my bitbucket account because bitbucket tells me that that key has already been added to an account. This means I have to generate a second key pair. So I run ssh-keygen -f ~/.ssh/jon -C "jon" as instructed here: https://confluence.atlassian.com/pages/viewpage.action?pageId=271943168 and then I add this jon.pub key to my jon account at bitbucket.

Now that I have two key pairs, id_rsa and jon, I have to configure which key gets used when. Following the instructions at the bitbucket help page linked to above, I create a config file in my ~/.ssh directory with the following contents:

Host devteam
 HostName bitbucket.org
 IdentityFile ~/.ssh/id_rsa
Host jon
 HostName bitbucket.org
 IdentityFile ~/.ssh/jon

I am then informed that I can make the following substitution: From [email protected]:jon/reponame.git to git@jon:jon/reponame.git

So I try to execute the following command: git clone git@jon:jon/reponame.git and I get the following error:

Initialized empty Git repository in /home/jon/dev/reponame/.git/
Bad owner or permissions on /home/jon/.ssh/config
fatal: The remote end hung up unexpectedly

What did I do wrong?

Edit: Here are the file permissions in my ~/.ssh directory:

[jon@linuxmachine ~/.ssh]
 1$ ls -alh
total 32K
drwx------.  2 jon 4.0K Jan 18 19:20 ./
drwx------. 11 jon 4.0K Jan 18 19:34 ../
-rw-rw-r--.  1 jon  132 Jan 18 19:20 config
-rw-------.  1 jon 1.8K Jan 18 15:21 id_rsa
-rw-r--r--.  1 jon  406 Jan 18 15:21 id_rsa.pub
-rw-------.  1 jon 1.7K Jan 18 18:45 jon
-rw-r--r--.  1 jon  390 Jan 18 18:45 jon.pub
-rw-r--r--.  1 jon  808 Jan 18 18:40 known_hosts

Answer 1

I had the same problem. After i changed permissions of the file ~/.ssh/config to -rw-r--r--, the error

Bad owner or permissions on /home/username/.ssh/config
fatal: The remote end hung up unexpectedly

disappeared.

Write in console:

cd ~/.ssh
chmod 644 config
