没有密码短语的sudo -u Git克隆

Question

I have user - dev with ssh config like this:

Host *
  IdentityFile ~/.ssh/id_rsa

If I login as this dev user (sudo su dev) and try to clone, everything works fine. Clone used without passphrase.

But when I use command like this:

sudo -u dev git clone repositoryurlhere

I always see:

Enter passphrase for key '/home/dev/.ssh/id_rsa'

How to get rid of this?

Answer 1

The file /home/dev/.ssh/id_rsa is encrypted. You probably had to enter a passphrase a few minutes agon when you were still dev , but forgot you did. After entering the password your keychain usually remembers it for a few minutes (similar to sudo , you need to enter your password only every few minutes).

When you switched to another user and then used sudo -u dev , that remembered password was gone and you had to re-enter the password.

The only solution is to remove the password from the identity file using

ssh-keygen -p -N "" -f /home/dev/.ssh/id_rsa

Afterwards you won't have to enter a password, neither as dev nor when using sudo -u dev .
