I just put
/pub/Linux-source/admutil-1.0.tar.Z
on
ftp.daimi.aau.dk (130.225.16.27)
It includes source for a better last(1) and setgrp(1) both by Michael Haardt,
plus a SYSV compatible init(8) program with runlevels and all.
This init was written by Miquel van Smoorenburg for Minix, and I ported it to
Linux with little effort.
There's also a shutdown(8) program as well as passwd(1) and chsh(1).
You should be able to build the binaries with both gcc 1.40 and gcc 2.1.
Follow the instructions in the Makefile and README.
Be warned that the init program is fairly untested, and I don't use it myself.
It's very easy to lock your self out of the machine if you do something wrong
with init and the new inittab format, so be sure you know what you are doing
before you install the new init.
There's also a problem with putpwent(3) in the older versions of libc, and if
you don't fix this or use the newest gcc 2.1 libc (later than 10-Apr-92) then
chsh and passwd will trash the /etc/passwd file and make it hard to log into
the machine afterwards.

The admutil-1.0.tar.Z package which includes this has been available
for some time now, but I keep getting mail from people who miss features
that are already in that package, so maybe my first announcement didn't
make it everywhere.
The admutil-1.0 package includes the following:
* setgrp - like su(1) but sets the group id only.
* shutdown - shuts down the system, putting correct entries into wtmp
and provides for timed shutdowns.
* passwd - changes passwords
* chsh - changes ones shell
* last - an improved last(1) command
* init - a Sys V compatible init(8) with run-levels and all, but not tested
very much.
A bug in some versions of libc makes passwd and chsh garble the passwd file,
so be careful.
asm1@ukc.ac.uk mailed me and asked for a lastlogin feature in the login
program.
Most of the code was already in login.c so here is a small patch to login.c
from the poeigl-1.2.tar.Z package:

if ((fd = open(_PATH_LASTLOG, O_RDWR, 0)) >= 0) {
(void)lseek(fd, (off_t)pwd->pw_uid * sizeof(ll), L_SET);
if (!quiet) {

if (!quiet) {

The package can be ftp'ed from:
ftp.daimi.aau.dk:/pub/Linux-source/admutil-1.0.tar.Z
The IP number is 130.225.16.27
Or you can get it from:

Keywords: init, getty, login, shutdown, su, passwd, chsh...
Date: 5 Jul 92 12:03:14 GMT

I have just uploaded these two packages
admutil-1.1.tar.Z
poeigl-1.4.tar.Z
to the following archives:
nic.funet.fi:/pub/OS/Linux/incoming
banjo.concert.net:/pub/Linux/Incoming
tsx-11.mit.edu:/incoming
ftp.daimi.aau.dk:/pub/Linux-source
The poeigl-1.4 package contains source for init, getty, and login and a few
other small utilities. The main change since 1.3 has been the addition of
a SIGINT handler to init that will gently reboot the machine when one presses
Ctrl-Alt-Del.
The admutil-1.1 package contains source for shutdown, su, chsh, passwd, and
a System V compatible init. Several small changes and additions have been
made since 1.0, most notably the addition of a new su(1) program, and
the shutdown source has been cleaned up a bit.
Both packages compile cleanly with gcc 2.2.2 and run under Linux 0.96b-PL2.
I hope the maintainers of the archives see this message and moves the
packages into their proper directories.
- Peter.

This is an announcement of the availability of version 1.5 of the poeigl
package, and version 1.2 of the admutil package.
Both of the new packages just contains bugfixed versions of the programs
in the previous packages, and no new features have been added.
Acknowledgements:
-----------------
d88-jwn@nada.kth.se made me avare of a fault in passwd.c concerning digits
in passwords.
hyvatti@cc.helsinki.fi (Jaakko Hyvatti) provided a fix for a nasty bug in
login.c, concerning unknown usernames and secure terminals.
I forgot who made me avare of the fact that shutdown would hang if /etc/utmp
somehow was corrupted. This should not happen anymore.
As always, the packages contains only sourcecode. The binaries can be built
under Linux 0.97 or later with at least gcc-2.2.2
To those that do not already know, the poeigl package contains:
init, getty, login, hostname, mesg, users, who, write
and admutils contains:
chsh, ctrlaltdel, init, last, newgrp, passwd, shutdown, reboot,
halt, su
I have put the packages out for anon ftp at:
ftp.daimi.aau.dk:/pub/Linux-source
tsx-11.mit.edu:/pub/linux/< whereever tytso puts them>
nic.funet.fi:/pub/OS/Linux/< whereever arl puts them>

I just uploaded poeigl-1.6.tar.Z and admutil-1.3.tar.Z to nic.funet.fi
and tsx-11.
Login now uses the new vhangup() syscall to prevent others from snooping
at the tty for passwords and other goodies.
There is also a new getpass() routine based upon some BSD code, as it has
become evident that the version that I contributed to libc, doesn't work
with telnet over TCP/IP. I hope the new version works better, but I haven't
been able to test it, because I haven't got a TCP/IP kernel.
The passwd program is changed a little to allow passwords with only lowercase
letters when there is at least one special character or digit in it.
It also explicitly prevents the use of ones username as password.
The shutdown program now tries even harder to avoid getting stuck when
/etc/utmp is corrupted.
Acknowledgements:
-----------------
Ross Biro < bir7@leland.stanford.edu> made me avare of the vhangup() call.
Johan W}hlin < d88-jwn@nada.kth.se> provided the fix for passwd.c
My thanks to both of them.
