allow a certain user only access at console

[Jeroen_D]

Hello,

how can you allow a certain user access to the console and only to the console ?

We use a certain account called rroot. When logging in as rroot, a script is launched. That script contains a lot of sysadmin tasks.

How can I prevent this person to login from the network ?

TIA,
Jeroen.

Hi !

/etc/securetty good for only root user.

Other users:
Edited the (default) profiles, when user use console continue, else exit shell.
use tty command for this.

Hi Jeroen,

You could add an entry in that user's .profile, checking for the tty.

Like this:

if [ `tty` != /dev/console ]
then
echo "You must log in from console"
exit 1
fi

Best regards,

Dan

Hi,
Sandor and Dan are correct, I thought your rroot was a root alias (uid 0)in which case the securetty would have been enough (since only users with UID 0 can only connect at the console) but then you would have to avoid the user to do an su...
Follow Dan's advice...
