Currently the latest versions +of this software is maintained at ftp://ftp.daimi.aau.dk/pub/linux/poe/ + +LICENSE: +This software is distributed as is without any warranty what so ever. +With respect to copyrights it is covered by the GNU Public License. + +Version 1.14 (12-Feb-95): + Added options -l, -y, -i to last.c. See last.man + +Version 1.13d (26-Jan-95): + Added some comments on request from Rik Faith. Compiled succesfully + on Linux 1.1.73, GCC 2.5.8, libc 4.5.26 + +Version 1.13c (6-Dec-94): + New versions of passwd and chsh due to Alvaro Martinez Echevarria + <alvaro@enano.etsit.upm.es>, so they will coexist with YP/NIS + passwords. + +Version 1.13b (7-Nov-94): + Use fgets() + atoi() in chsh.c instead of scanf(). + +Version 1.12 (17-Sep-94): + Rik Faith provided patches for passwd.c to let non-alphabetics count + as digits as well, allows more obscure passwords. + + Applied patches from Dave Gentzel <gentzel@nova.enet.dec.com> + to prevent dereferencing a NULL pointer, and turn off accounting + in shutdown.c + +Version 1.11 (18-Aug-94): + Finally got around to making it a non-alpha version. Just a + little cleanup in Makefile + +Version 1.10b (8-Jun-94): + David A. Holland <dholland@husc.harvard.edu> made me aware of a + security leak in passwd and chsh. /etc/ptmp could be forced to + be world-writeable. Fixed by hardwiring an umask of 022 into + passwd and chsh. + + Vesa Ruokonen <ruokonen@taivas.lut.fi> sent me a new pathnames.h + file that shouldn't conflict with paths.h. + + Cleaned the source a bit for -Wall + +Version 1.10a (31-May-94): + Vesa Ruokonen <ruokonen@taivas.lut.fi> provided a patch for + passwd.c such that it will work for multiple usernames for + the same uid. I mimicked his actions on chsh.c. In both cases + I added a check to ensure that even if utmp is hacked, one can + only change the password for users with the same uid. + +Version 1.9 (9-Feb-94): + Vesa Ruokonen suggested that newgrp should support passwords in + /etc/group. It now does. I mostly rewrote newgrp to make it + cleaner. + +Version 1.8 (19-Jan-94): + Rik Faith provided several patches, especially for passwd.c and + some man-pages. + +Version 1.7 (3-Nov-93): changes since 1.6 + Shutdown can now be used as a login shell. I forget who sent me the + patch. Example /etc/passwd entry: + + shutdown:dLbVbIMx7bVHw:0:0:Stopper:/:/etc/halt + + The package should now be prepared to have shutdown in /sbin as well + as in /etc. utmp and wtmp are allowed in /usr/adm too. Both things + are configurable in the Makefile. + + <flebbe@cygnus.tat.physik.uni-tuebingen.de> Olaf Flebbe provided a + patch for chsh.c to make it work. + + This version is built under linux 0.99.13 with gcc 2.4.3 and + libc 4.4.1 + +Version 1.6 (1-Jun-93) + Shutdown now looks more like shutdown on SunOS, but not quite. Most + of this was done by Scott Telford (s.telford@ed.ac.uk), but I + butchered his patches somewhat. This version was built under Linux + 0.99.9 with GCC 2.3.3 and libc 4.3.3. + + "make install" will now install shutdown in /etc instead of /usr/bin + +Version 1.5 (13-Dec-92) + This version is tested and built under Linux 0.98P6 with gcc-2.2.2d7 + You will have a hard time making it work with the older compilers and + libraries. + + Su is now deprecated. I believe that the GNU/FSF version is better. + +CONTENTS. +last - A new and better last command, a port from BSD done by + Michael Haardt. + I put a couple of if's in so LOGIN_PROCESS entries in wtmp + are not printed. + +chsh - CHangeSHell changes the shell entry in the passwd file. + Written from scratch by me. + +passwd - Changes the password in the passwd file. + Also done from scratch by me. + +su - A su(1) command by me. + +newgrp - Sets the gid if possible, ala su(1), written by Michael + Haardt. + +shutdown - Shuts down linux. Supports timed shutdowns, and sends + warnings to all users currently logged in. It then + kills all processes and unmounts file-systems etc. + + Shutdown also doubles as halt and reboot commands. + + Shutdown leaves the file /etc/nologin behind after shutdown, + it is wise to have a "rm -f /etc/nologin" in ones /etc/rc + + Shutdown now supports a -s switch, that works in connection + with the init program in poeigl-1.7 or later, so a singleuser + reboot is possible. + + Rick Sladkey <jrs@world.std.com> provided patches for better + umounting code, needed in connection with NFS. + + Remy Card <card@masi.ibp.fr> provided patches for support for + fastboot/fasthalt. These create a /fastboot file on shutdown, + and /etc/rc may check for the existance of this file, to + optionally skip fsck. + +example.rc An example of an /etc/rc file. Edit it to suit your own setup. + +ctrlaltdel - Sets the behaviour of the Ctrl-Alt-Del combination. + "ctrlaltdel hard" makes the key-combination instantly reboot + the machine without syncing the disk or anything. This may + very well corrupt the data on the disk. + + "ctrlaltdel soft" makes the key-combination send a SIGINT to + the init process. Such a command would typically be in /etc/rc. + For this to make sense you must run the init from the + poeigl-1.4 package or later. The System V compatible init in + this package won't reboot the machine when it gets a SIGINT. + Linux version 0.96b-PL1 or later is also needed for this + feature to work. + +init is gone as of V1.5, it was outdated and buggy. If you want a +SYSV compatible init get the newest one from Mike Smoorenburg, called +sysvinit.tar.Z + +INSTALLATION. +Simply do a + + make + +and then (optionally) as root: + + make install + + + - Peter (poe@daimi.aau.dk) |
