Trouble cloning a git repository from an EC2 instance

Solution 1

Check to make sure git is doing what you think it is doing, and then try the exact command git is using to contact the remote server.

Run GIT_TRACE=1 git clone [email protected]:/opt/git/project.git

Git will tell you what command it is running, ex

trace: run_command: 'ssh' '[email protected]' 'git-upload-pack '\''/opt/git/project.git'\'''

You can then try to run that command yourself to eliminate git from the picture:

ssh [email protected] git-upload-pack '/opt/git/project.git'

While it seems unlikely given your reported error message, stracing the command can also provide hints:

strace -o/tmp/tr -s128 -f ssh [email protected] git-upload-pack '/opt/git/project.git'

Report back the debugging information revealed above if there are still problems.

Solution 2

Interesting. I was having a similar problem trying to clone from an external GIT source to an EC2 host. I got things working using some of the above.

It had been failing with:

[ec2-user@*.*.*. mediagoblin]$ sudo git clone git://gitorious.org/mediagoblin/mediagoblin.git
Cloning into mediagoblin...
gitorious.org[0: 87.238.52.168]: errno=Connection timed out
gitorious.org[0: 2a02:c0:1014::1]: errno=Network is unreachable
fatal: unable to connect a socket (Network is unreachable)

I then tried replacing git:// with ssh:// and got:

sudo git clone ssh://gitorious.org/mediagoblin/mediagoblin.git
Cloning into mediagoblin...
The authenticity of host 'gitorious.org (87.238.52.168)' can't be established.
RSA key fingerprint is *:*:*:*:*:**:.  
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'gitorious.org,87.238.52.168' (RSA) to the list of known hosts.
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

I then ran the original git:// request and it worked.

I hope that helps.

    I'm attempting to put a bare git repository on a ubuntu server running on Amazon EC2. The difficulty I'm having is getting git to clone the repository from my local pc.

    When I try:

    git clone [email protected]:/opt/git/project.git
    

    I get:

    Cloning into project...
    Unable to open connection:
    Host does not existfatal: The remote end hung up unexpectedly
    

    Yet I don't have any difficulty ssh'ing into the same server. For example the following works fine:

    ssh [email protected]
    

    My thinking was that if this is working, then I have my keys set up appropriately on the client, and on the server. Therefore the git clone command should work as well.

    But no.

    I've researched and tried a number of variations, but I just have hunch I'm missing something brain dead simple.

    In process of trying your suggestion. But do you need more than read access for a clone?

    Really? I thought that git worked over the ssh protocol (port 22), which is what I was attempting to do. I have ports 80 and 22 open. I'm not using a git server (gitosis?).

    Only git protocol / git daemon is 9418

    Thanks for the debug help. It gave me a few ideas. I can't explain why, but the upgrading my version of msysgit 1.7.3.1 preview to 1.7.4 preview seemed to solve the problem. I was hoping for something clearer than that, but there you have it.
