Hi,  
I'm stuck integrating a GIT repository using ssh-keys.  
I have the NodeRed 1.1.3 (latest now) and a gitea Installation 1.12.4 (latest now)

When I try to clone a repo from the GIT server it failes.  
I'm using the GIT URL git@hostname.fqdn:gitrepo/test.git

Log from Node-Red (trace):

```auto
18 Sep 11:28:20 - [trace] runGitCommandWithSSHCommand {"key_path":"/home/wf/.node-red/projects/.sshkeys/admin_zui","passphrase":""}

18 Sep 11:28:20 - [debug] [err] and the repository exists.
18 Sep 11:28:20 - [debug] rc=128

```

When I try to do the same manually it works

```auto
vim /home/wf/.ssh/config
#Add the 2 lines:
---
Host hostname.fqdn
    IdentityFile /home/wf/.node-red/projects/.sshkeys/admin_zui
---

wf@hostname:/tmp/j$ git clone git@hostname.fqdn:repo/test.git
Cloning into 'test'...

remote: Total 3 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (3/3), 238 bytes | 0 bytes/s, done.

```

Do you have any idear what goes wrong or how to generate more debug data?  
The following line seems a little strange, but I'm not sure.  
`git -c credential.helper= clone ssh://git@hostname.fqdn:gitrepo/test.git .`

Thanks for any hint

Try without the `ssh://` at the start of the git url when you enter it in the ui.

I can see the following log-messages in /var/log/auth.log. It seems that node-red doesn't correctly try to use key based authentication, but instead user/password.

```auto

Sep 18 13:34:40 hostname sshd[13677]: Failed password for git from 192.168.1.11 port 56653 ssh2
Sep 18 13:34:40 hostname sshd[13677]: Failed password for git from 192.168.1.11 port 56653 ssh2
Sep 18 13:34:40 hostname sshd[13677]: Connection closed by 192.168.1.11 [preauth]

```

@knolleary: Nick, can you tell me which git commands NodeRed launches? Even with all debugging enabled I can't find a reason why its failing...  
I would be very happy for any support 🙂

You can see the git commands it runs in the log -

```auto
18 Sep 11:28:20 - [trace] git["clone","ssh://git@hostname.fqdn:gitrepo/test.git","."]
18 Sep 11:28:20 - [debug] git -c credential.helper= clone ssh://git@hostname.fqdn:gitrepo/test.git .

```

@knolleary: Thank you 🙂 I'm totally lost to debug this issue.

So I'm able to authenticate using ssh-key with git by explicitly setting my project-key as key in ~/.ssh/config, otherwise it fails.  
The question is: How does this credential.helper thing work in node-red (Actually: How does node-red pass the pub-key to git).  
Is it possible. that for node-red uses the environment Variable ```  
GIT\_SSH\_COMMAND="ssh -i ~/.ssh/id\_rsa\_example"

```auto
to pass the key? Actually I'm using git < 2.3.0 and this variable is supported with git >= 2.3.0
```
