secure root access with SUDO
 
Hallo all,

Is there anyone that are expert on SUDO?

I want to let a few administrators get the privilege to run ROOT command with sudo, I have added them to wheels group on my RedHat server and it works fine to run the ROOT commands.

But I want to secure it even more if possible, I want instead of they use their user-password to use sudo, want's I to use RSA key authentication.

Do anyone know if it possible to get sudo to work with key-authentication?

Thanks in advance!

Cheers

Düssel

its quite easy to set this up in sudo without keys.

why do you want to use keys? to run commands on remote hosts or something?

As he mentioned, he just wants more security.

The "-a" switch in the sudo manpage states that other authentication methods may be used, but does not say if key-authentication is among them.

yeah i realise, that but i'm not sure how keys would be appropriate here. what are you exchanging public/private keys between?

No, I only got the idea of it when I read of a really old open-source project (ssu (secure su)), but it looks like it is not active any longer. It sounded as quite interesting idea they had, so I hoped that SUDO mabe also had implemented a little such possibilities also.

I will test with -a, it is always fun to check out new things.

Thanks for the tip with -a!
