ssh cannot connect to git server in php

Question

I am able to connect and interact with a remote git server via terminal but am unable to do so with PHP. I am trying to execute the following command:

GIT_SSH_COMMAND="ssh -vvv -i ~/.ssh/id_rsa -F /dev/null" \
/usr/local/bin/git push -u origin master

If I do the same command in the terminal it works no problem. I have searched the internet for answers and haven't been able to find a solution that works.

Now keep in mind the repo does not exist yet. I am trying to create it via this command. I did successfully create another repo minutes before with this exact command. Any idea what I am missing?

Here is the debug output.

read_passphrase: can't open /dev/tty: Device not configured" <- there's your problem. Also, is /Users/greenorange/.ssh/id_rsa the private key you expect to load? — Phil

Yes, that is the correct private key. How can I remedy that error and why am I not seeing it when running the command in my terminal? — brenjt

You probably have an ssh-agent running. See help.github.com/articles/working-with-ssh-key-passphrases. One solution for machine-account private keys is to not have a passphrase — Phil

Okay, That makes sense. Any suggestions on how I can remedy the problem? Would I just need to use a new rsa key that doesn't have a passphrase attached to it? — brenjt

The problem is identified here

read_passphrase: can't open /dev/tty: Device not configured

Your private key requires a passphrase which cannot be entered because there is no terminal. You may not be seeing this when you run the command in your terminal due to your ssh-agent.

See https://help.github.com/articles/working-with-ssh-key-passphrases/

One solution is to create a new key pair for the remote service without a passphrase.

The security implications of this are whatever remote services that have the new public key are now only as secure as the copy of the private key (ie, your local machine account). Assess that risk however you like.
