Hi,
Is it possible to have in Linux different root passwords, for the same
machine: one for accessing it inside the intranet and another for
accessing through the internet ?
I suppose one way to do this would be to set up 2 root accounts. This is done
by adding another user, and then manually changing the uid in /etc/passwd for
that user to 0. The 2 users (one of which will probably be called 'root') can
have different passwords.
or: useradd -o -u0 secondroot
Far better than allowing users to remotely login as root is to
allow specific NON-root users to login and execute root-perm
commands via the sudo command functionality.
Generally, if you allow remote root logins, you should do so via
rsa key logins... This requires people doing remote logins to have
both an authorized ssh key and the the password to decrypt it.
When you have SSH keys, you can also permit that key to only execute
specific commands (which makes life much safer).
( `man sshd` for more info on the authorized_keys file)
