sunOS 4.x.x root login
I have an old (I mean "dinosaur old") server that is running SunOS 4.1xxx.

I need to allow root login ONLY on the console. I've looked in /etc/default for the login file for the "console=/dev/console" parameter is, but there's no 'default" dir in /etc.

Can someone help?

Thanks

documentation for 4.1.x is sparse

From fsu.edu:
Quote:
1. login as "root", if allowed in /etc/ttytab (BSD):

#
# @(#)ttytab 1.7 92/06/23 SMI
#
# name getty type status
#
console "/usr/etc/getty cons8" sun on local secure
ttya "/usr/etc/getty std.9600" unknown off local secure
ttyb "/usr/etc/getty std.9600" unknown off local secure
ttyp0 none network off secure
ttyp1 none network off secure

Field 1: "/dev" device name (e.g., "/dev/ttya")
Field 2: program to monitor that line ("getty", "xdm")
Field 3: Type of terminal (in "/etc/termcap")
Field 4 and up: List of attributes for that line

"on" == start up process in field 2
"local" == use local connection line discipline (or lack thereof)
"secure" == "root" allowed to log on
found at fsu.edu - lectures

More info specific to 4.1.3 - hopefully it will work with yours - see Security on SunOS 4.1.3

Thanks that's just what I needed.

I edited (after copying the original file) the ttytab file and deleted the 'secure' flag on all the devices, except for console.

It now blocks remote root logins. *whew!* Smilie
