This is a message I wrote to MkLinux-Setup,
Subject: Re: cannot login as root
See: man group , man ttys , man su
The rule(s) in the UNIX world:
You logon as yourself. And when needed, you su to root.
You logon as root from the console only.
It is normal practice to logon as root only at secure stations,
and this means only via the console. In all other cases
you logon as a user of group root (or wheel on *BSD) and su to
root when needed. This forces anyone attempting to gain root
access to your machine to know a valid username:password
combination first.
Then there is the risk of doing damage to the system by logging in
as root all the time or walking away from the workstation while
logged in as root. Most work on the system can be performed as a
normal user.
Logging in as root except at the console (to recover from a crash
or other disaster) is a sign of inexperience and bad work habits.
Restricting Access consists of controlling:
Physical Access to the:
server
network
workstations
Electronic Access from:
LAN
WAN
Dial-up
Remote console sessions
File Access
User and Group permissions
" Stamp out root login's . . . . su "
