Unable to clone using git in Linux Mint using my custom key

Question

In my pc I setup a file named ~/job/ssh/config

Host bitbucket
 HostName bitbucket.org
 IdentityFile ~/job/ssh/rsa_key
 user git
 IdentitiesOnly yes

and in my ~/.ssh/config

~/.ssh/config 
Include /home/pcmagas/job/ssh/config

And the folder ~/job/ssh has the following settings:

-rw------- 1 pcmagas pcmagas  191 Σεπ  15 10:57 config
-rw------- 1 pcmagas pcmagas 3414 Σεπ  15 10:45 rsa_key
-rw------- 1 pcmagas pcmagas  761 Σεπ  15 10:45 rsa_key.pub
-rw------- 1 pcmagas pcmagas  419 Αυγ  28 15:32 work
-rw------- 1 pcmagas pcmagas  109 Αυγ  28 15:32 work.pub

By doing:

$ ssh bitbucket
PTY allocation request failed on channel 0
authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled
Connection to bitbucket.org closed.

Also I can:

 ssh -i ~/job/ssh/rsa_key [email protected]
PTY allocation request failed on channel 0
authenticated via ssh key.

You can use git to connect to Bitbucket. Shell access is disabled

I can connect to bithubket.

Firthermore by doing:

GIT_SSH_COMMAND='ssh -i ~/job/ssh/rsa_key -o IdentitiesOnly=yes' git clone [email protected]:exampe/myproj.git

I can clone it:

Γίνεται κλωνοποίηση μέσα στο 'myproj'...
remote: Enumerating objects: 210004, done.
fetch-pack: unexpected disconnect while reading sideband packet

But I cannot without the variable. Any ideas what's wrong?

As a means of mitigation I also tried to comment the inclide line in ~/.ssh/config and placing these stuff in to ~/.ssh/config directly:

Host bitbucket
 HostName bitbucket.org
 IdentityFile ~/job/ssh/rsa_key
 user git
 IdentitiesOnly yes

Furthermore I've run these commands as well:

chmod 400 ~/job/ssh/*
chmod +w ~/job/ssh/config

Answer 1

In order for this setting to work rename the entry:

Host bitbucket
 HostName bitbucket.org
 IdentityFile ~/job/ssh/rsa_key
 user git
 IdentitiesOnly yes

Into:

Host bitbucket.org
 HostName bitbucket.org
 IdentityFile ~/job/ssh/rsa_key
 user git
 IdentitiesOnly yes

This will trick the ssh-agent to use the key located upon ~/job/ssh/rsa_key instead of the ones located into ~/.ssh.

But I have seperate config file

This works both if the entry is in:

• ~/job/ssh/config
• ~/.ssh

For the first to work you must place the line:

Include /home/pcmagas/job/ssh/config

At ~/.ssh/config.
