I'm trying to use a newly generated elliptic curve key with git version control for GitLab.
- I am using a Xubuntu 16.04.
- My OpenSSH version is: OpenSSH_7.2p2 Ubuntu-4ubuntu2.4, OpenSSL 1.0.2g 1 Mar 2016
Usually I would do:
ssh-add -D # to be sure no other identities are used than the one I add ssh-add ~/.ssh/my-rsa-key git add ... git commit ... git push ...
Then the key ring thing would again ask for the password of the key to store it for the session and I could push and pull without needing to add any key again or entering the password again.
However with elliptic curve keys it does not seem to work. First of all, I cannot
ssh-add the key:
ssh-add ~/.ssh/id_ed25519 Enter passphrase for /home/user/.ssh/id_ed25519: # here I enter my password Could not add identity "/home/user/.ssh/id_ed25519": communication with agent failed
However, when I did not remove all identities and did not use
ssh-add <key> and cancelled entering a password for the key ring for other (rsa) keys, I was asked to enter the password for the elliptic curve key on command line and when I entered it there, I could push to or pull from my repository. The problem then is, that I have to enter my password on every interaction with gitlab and my repository. So I tried configuring my
~/ssh/config to not prompt for password all the time:
Host gitlab.com User "user" PreferredAuthentications publickey,password IdentityFile /home/user/.ssh/id_ed25519 IdentitiesOnly yes AddKeysToAgent yes
But that does not work either, it keeps nagging me about the password on every pull or push.
How can I add the keys like I do with RSA keys, so that I do not have to enter the password all the time?
