Archive-name: nogetty/part01
Properly used, nogetty allows one to start execution of a turnkey
application on a particular SCO UNIX V multiscreen from inittab
immediately entry upon a run level. All login and password
validation are bypassed.
DANGER WILL ROBINSON! Misuse of this program can compromise the
security of your system. Carefully read the README and thr source
file header for nogetty.c before use.

XProperly used, nogetty allows one to start execution of a turnkey
Xapplication on a particular SCO UNIX V multiscreen from inittab
Ximmediately entry upon a run level. All login and password
Xvalidation are bypassed.
X
XDANGER WILL ROBINSON! Misuse of this program can compromise the
Xsecurity of your system. Carefully read the source file header
Xfor nogetty.c before use.
X
XAlso provided is dumpwtmp.c, a program which displays utmp
Xand wtmp in exhaustive detail.
X
XI almost always provide a Makefile. But not this time. While
Xyou are typing, think again whether this is a program you want
Xto use or not.
X
XTo compile,
Xcc -O -o nogetty nogetty.c
Xcc -O -o dumpwtmp dumpwtmp.c
X
X(oh all right, 'make nogetty dumpwtmp' will probably do it too)
X
XTo install:
Xmv nogetty /etc/nogetty
Xchown bin /etc/getty
Xchgrp bin /etc/getty
Xchmod 100 /etc/nogetty
X
XThen, an inittab entry like:
X
Xc05:2:respawn:/etc/nogetty turnkey tty05 bake_turkey
X
Xwill continously respawn a process on tty05 with username 'turnkey'
Xand run program or shell script 'bake_turkey'

X
XDANGER WILL ROBINSON!
X----------------------
XBecause this violates Rules and Regulations of the C2 Brown Shirt
XPreservation League, I feel I must deviate from my usual lack of
Xverbiage. The is no 'F' TCB classification, but this program
Xwarrants creation of one.
X
X1. Misuse of this program can compromise the security of your system.
X
X2. Making this program setuid to root WILL completely and fully
X and probably PERMANENTLY compromise the slightest precepts of
X security on your system (System->Configure->Security->Drown).
X
X3. No attempt is made to set the LUID. The ultimate ramifications
X are unknown, but the immediate effects are to bypass much of
X the C2 ParanoidWare.
X
X4. Not only is there no warranty or guarantee on this software,
X but I don't want to even hear any of the horror stories possibly
X resulting from the casual use of this software.
X
XNOT ME! I DIDN'T DO IT
X----------------------
XNogetty is provided on an as-is basis. In no account will Warren Tucker
Xor any other individual or entity be held accountable or liable for
Xany direct or indirect consequences arising from the use of this
Xsoftware.
X
XTTY INITIALIZATION
X------------------
X1. ISIG is purposefully omitted from the initial tty setup so that
XRUBOUT (SIGINT) processing may not abort the started application.
XYou may wish to reenable it by use of 'stty isig'. Be aware that
Xsome applications when started may of their own accord enable
XSIGINT processing either directly or through the invocation of
Xother processes.
X
X2. A 'mesg n' is simulated by chmod 0600 of the terminal device.
X
X3. The tty is always initialized to 9600 baud, no parity, one stop bit.
X
X4. Otherwise, the tty is initialized pretty much as getty/login would.
X
XSUITABLE APPLICATIONS
X---------------------
XApplications started with nogetty that fork other processes
Xshould receive particular attention with respect to security.
XThe ability of a child process to executing a shell is of obvious
Xconcern, but bear in mind that starting programs like vi can be a
Xproblem since THEY have a shell capability. Of course, since you
Xare the god of your system, it is up to YOU to decide what is
Xbest for your child and behave as you feel best.
X
XAPPLICATION ENVIRONMENT
X-----------------------
XThe preferred (/etc/passwd) shell for <username> is started as
Xa login shell (i.e., .login will be executed if the shell is csh).
X
XTo allow for login processing to differentiate between normal
Xand nogetty startups, nogetty adds an environment variable
X NOGETTY=/dev/ttyxx
X
XThe single <command> is executed, whereupon nogetty exits.
X
XUTMP, INITTAB, WHO, ENABLE/DISABLE
X----------------------------------
XUtmp and wtmp are properly updated per the ad-hoc SCO usage of
Xutmp's ut_id. The ut_id field of the utmp entry for a *multiscreen*
Xis comprised of a 'c' followed by the last two (numeric) characters
Xof the tty id. Use of nogetty to start an application on a
Xnon-multiscreen will require analysis of the ut_id format and
Xuse of the '-i' switch.
X
XIf you handle this little bit, then you should be able to
Xuse all the standard features of inittab, who and enable/disable.
XOtherwise, erroneous utmp entries will be generated, adversely
Xaffecting these control and status functions.
X
XLOG FILE: /etc/nogetty.log
X--------------------------
XError logging is done in /etc/nogetty.log. It grows forever unless
Xyou do something about it.
