Dear All
I have an immutable script on server A, it executes a maintenance command on the remote servers where elevated privileges are needed.

I want the developers on server A to execute the script and run it without being prompted for a password.

The script contains scp root@serverB and ssh 'root@serverB', if run as root it runs great since I am using ssh keys. However, as regular users they are prompted for a password.

If I do created their group on server B...etc and give the group sudo it would still ask for passwords right ?

Can I overcome this ?

Regards

you can use a passphrase-less ssh-identity, or consider running an ssh-agent with the key you are using for scp loaded into it.

for example:

(as the sudo user)

ssh-agent > agent.sh
source agent.sh
ssh-add whatever.key

then in your script, just do source agent.sh before running the scp command.
