Question

My config file on ssh seems to systematicaly apply the * rule i don't know why ?

 Host gitlab_perso
  HostName gitlab.com
  User git
  PreferredAuthentications publickey
  IdentitiesOnly yes
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/perso/id_rsa

Host gitlab.com
 Hostname gitlab.com
 AddKeysToAgent yes


    UseKeychain yes
     IdentityFile ~/.ssh/id_rsa

   Host *
     AddKeysToAgent yes
     UseKeychain yes
     IdentityFile ~/.ssh/id_rsa

so only my default ssh key ( ~/.ssh/id_rsa ) is always use . How the ssh config works ? thank your for your help !

Answer 1

To use non-default key either use it explicitly:

ssh -i ~/.ssh/perso/id_rsa [email protected]

or use the host alias from your ssh config:

ssh gitlab_perso

If you need to use the key in git you have to change the host in remote's URL:

git remote set-url origin git@gitlab_perso:user/repo.git
