Add remote with ssh protocol and key - how to troubleshoot issue?-CodePudding

I am trying to add a remote address to a branch, but when trying to fetch, or do git ls-remote , I get Permission denied:

[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

So I'm wondering how to troubleshoot this? I tried using regular command line and Git bash.

It worked when I tried a different repo and server, connecting with root user in the same way:

git remote add prod ssh://[email protected]:22/myfolder/gittest.git

The successful message is: From ssh://[email protected]:22/myfolder/gittest.git

On the problematic server the user has access and I can ssh with no problem , I specify a key at the same time:

ssh -i .ssh/mykey.pem [email protected]

When I try to add the remote to the server, I do this:

git remote add prod ssh://[email protected]:22/myfolder/gittest.git

But it needs the .pem file , so I've specified it in .ssh/config:

Host theserver
 HostName 22.22.22.222
 IdentityFile ~/.ssh/myfile.pem
 Port 22

How can I verify that the .pem file being read? If I remove the text from config, there is no error about "missing key" or anything?

The folder exists on the server: /myfolder/gittest.git (myfolder is at the root). I also tried to a differemt location for the repo, moving it into a sub directory to the user. But it's the same error.

So how can I pinpoint the problem?

If it's of any use, when I check the user on the server: id myuser I get:

uid=1000(myuser) gid=1000(myuser) groups=1000(myuser),4(adm),20(dialout),24(cdrom),
25(floppy),27(sudo),
29(audio),30(dip),33(www-data),44(video),46(plugdev),119(netdev),120(lxd)

CodePudding user response：

You have the (mostly) correct host alias set up in your configuration. Your URL just has to reference it. So define theserver as you are, but include the user name as well.

Host theserver
 User myuser
 HostName 22.22.22.222
 IdentityFile ~/.ssh/myfile.pem
 Port 22

Now configure git with

git remote add prod theserver:myfolder/gittest.git

When trying to connect to theserver, SSH will look for a Host entry with that name. What it won't do is take ssh://[email protected]:22/myfolder/gittest.git and look for a Host block with the same address.

CodePudding user response：

Use IdentitiesOnly yes in .ssh/config like this

Host theserver
 HostName 22.22.22.222
 IdentityFile ~/.ssh/myfile.pem
 Port 22
 IdentitiesOnly yes

Otherwise default ~/.ssh/id_rsa will be tried before
