Identity Not Working if adding "IdentitiesOnly yes" to *
I have a config file in .ssh here
Host *
AddKeysToAgent yes
IdentitiesOnly yes
#Github (default)
Host gh
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa
#Bitbucket (secondary)
Host bb
HostName bitbucket.org
User git
IdentityFile ~/.ssh/id_rsa_bb
#Azure DevOps (secondary)
Host ado
HostName ssh.dev.azure.com
User git
IdentityFile ~/.ssh/id_rsa_ado
IdentitiesOnly yes
#GitLab
Host gitlab.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_gl
If I have IdentitiesOnly yes set in the * host, I cannot SSH to bitbucket, but all of the other connections work:
% ssh -T git@bitbucket.org
git@bitbucket.org: Permission denied (publickey).
Removing the IdentitiesOnly config causes the bitbucket ssh to work. I’ve tried reloading the identity as well with
ssh-add ~/.ssh/id_rsa_bb
That would suggest the public key configured in the authorized_keys file (or equivalent) for git@bitbucket.org might not actually be the one corresponding the private key in ~/.ssh/id_rsa_bb, but one of the other keys available in the agent.
Try ssh -v -T git@bitbucket.org with IdentitiesOnly set to no, and read the debug messages to see which key is actually accepted by the remote host.
