无法使用SSH代理转发运行git命令

Question

I want to run a git command on my VPS server, as in the following:

ssh -A user@mydomain.com 'git ls-remote git@bitbucket.org:myuser/repo.git'

but I get the error message:

Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

I can run other commands using SSH agent forwarding. (On other servers, this commands works fine.)

Answer 1

The "Host key verification failed" message likely means that the SSH client on your VPS doesn't trust the git server.

Try this instead:

ssh -A user@mydomain.com 'ssh -T -o StrictHostKeyChecking=no git@bitbucket.org < /dev/null'
ssh -A user@mydomain.com 'git ls-remote git@bitbucket.org:myuser/repo.git'

The first command should cause the SSH key to be cached in your .ssh/known_hosts on the VPS. From then on, the second command should work.

You could probably also solve this by creating a .ssh/config on the VPS user account, containing something like this (untested):

Host bitbucket.org
    User git
    StrictHostKeyChecking no

Assuming the above configuraiton snippet works, it would save you one SSH connection.
