Compile with - -DSHADOW_PWD if you have <shadow.h>. This is on by default. - By Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl>. - Changed the wtmp locking scheme in login.c,agetty.c,simpleinit.c - to flock() /etc/wtmplock instead of the wtmp file directly. - This avoids a denial of service attack. - Some support for the RB-1 Cryptocard token for challenge/response - authentication.

Fix by Gerhard Schneider <gs@ilfb.tuwien.ac.at> - -Version 1.42c (6-Nov-96): - Small fix by Gabriel M. Schuyler <schuyler@easiest.com>, to get - better syslog messages (1 LOGIN FAILURE instead of 2 LOGIN FAILURES). - Patch butchered by me. - -Version 1.42b (30-Sep-96): - Got patch for checktty.c from Christoph Lameter - <clameter@miriam.fuller.edu> so it doesn't traverse the groupfile - "manually" but uses the getgroups() call, this is more efficient - with large groupfiles and NIS/YP. - -Version 1.42a (24-Sep-96): - Added extra syslog() call to login.c to log all good logins. - Patch from Steve Philp. - -Version 1.41 (20-Jul-96): - Added security fix to checktty.c by JDS to clear certain lists. - Patches butchered and ANSI'fied by me. - Added -n option to agetty to avoid the login prompt. - -Version 1.40a (29-Dec-95): - Added -f <issue_file> option to agetty. Patches from Eric Rasmussen - <ear@usfirst.org>, but somewhat butchered by me. - -Version 1.39 (25-Oct-95): - Lots of testing and bugfixes in agetty. Now the modem init stuff - should finally work (for me). Also wrote modem.agetty as an example - on how to use agetty with a modem. - Agetty now also supports baud rates of 38400, 57600, 115200 and - 230400 bps. - -Version 1.37 (15-Sep-95): - Added -I <initstring> and -w options to agetty.c for those that - use agetty with modems. - -Version 1.36 (25-Aug-95): - Enhanced /etc/usertty features with group support. Moved this part - of login.c to checktty.c. One can now define classes of hosts and - ttys and do access checking based on unix-group membership. See - login.1. Also time ranges for logins can be specified, for example - writing the line - - joe [mon:tue:wed:thu:fri:8-16]@barracuda [mon:tue:wed:thu:fri:0-7:17-23]@joes.pc.at.home [sat:sun:0-23]@joes.pc.at.home - - says that during working hours, Joe may rlogin from the host - barracuda, whereas outside working hours and in weekends Joe may - rlogin from his networked PC at home. - - login.c: failures was not properly initialized, it now is. Also - made sure ALL failures are really logged to syslog. - -Version 1.35 (7-Aug-95): - login.c: Much improved features for the usertty file, allows - access control based on both hostnames/addresses and line. See the - about.usertty file and the man-page. - - Fixed agetty so it doesn't fiddle with the ut_id field in the - utmp record, this should prevent growing utmps on systems with - more than 10 login lines. Fix suggested and checked by Alan Wendt - <alan@ezlink.com> in his agetty.1.9.1a. - - Agetty now installs as agetty again, not as getty. - Updated man-page for login(1) to document /etc/usertty changes. - - This has been tested on Linux 1.2.5 with GCC 2.5.8 and libc 4.5.26. - -Version 1.33a (20-Jun-95): - rchatfie@cavern.nmsu.edu ("rc.") suggested that I should remove - the #ifndef linux around the special logging of dial-up - logins. This is now done, so each login via a serial port - generates a separate DIALUP syslog entry. - -Version 1.33 (5-Jun-95): - Patch by Ron Sommeling <sommel@sci.kun.nl> and - jlaiho@ichaos.nullnet.fi (Juha Laiho) for agetty.c, used - to return a pointer to an automatic variable in get_logname(). - Many patches from or via Rickard Faith <faith@cs.unc.edu>, fixing - man-pages etc, now defaults to using /var/log/wtmp and /var/run/utmp - according to the new FSSTND. - - Fix in login.c for CPU eating bug when a remote telnet client dies - while logging in. - - This is for Linux 1.2, GCC 2.6.2 or later. - -Version 1.32b (12-Mar-95): - Login now sets the tty group to "tty" instead of "other". Depending - on compile-time define USE_TTY_GROUP the tty mode is set to 0620 or - 0600 instead of 0622. All as per suggestion by Rik Faith and the - linux-security list. - Write/wall now strips control chars except BEL (\007). Again after - suggestion by Rik Faith. - -Version 1.32a - Urgent security patch from Alvaro M. Echevarria incorporated into - login.c. This is really needed on machines running YP until - the libraries are fixed. - -Version 1.32 - Login now logs the ip-address of the connecting host to utmp as it - should. - -Version 1.31b (2-Feb-95): - Daniel Quinlan <quinlan@yggdrasil.com> and Ross Biro - <biro@yggdrasil.com> suggested a patch to login.c that allows for - shell scripts in the shell field of /etc/passwd, so one can now - have (as a line in /etc/passwd): - bye::1000:1000:Outlogger:/bin:echo Bye - Logging in as "bye" with no password simply echoes Bye on the screen. - This has applications for pppd/slip. - -Version 1.31a (28-Oct-94): - Scott Telford provided a patch for simpleinit, so executing reboot - from singleuser mode won't partially execute /etc/rc before - the reboot. - -Version 1.30 (17-Sep-94): - tobias@server.et-inf.fho-emden.de (Peter Tobias) has made a more - advanced hostname command that understands some options such as - -f for FQDN etc. I'll not duplicate his work. Use his hostname - package if you wish. - - svm@kozmix.xs4all.nl (Sander van Malssen) provided more features - for the /etc/issue file in agetty. \U and \u now expand to the - number of current users. - - It is now possible to state the value of TERM on the agetty command - line. This was also provided by Sander. - - This has been built under Linux 1.1.42 with gcc 2.5.8 and libc 4.5.26. - -Version 1.29 (18-Aug-94): - Finally got around to making a real version after the numerous - alpha versions of 1.28. Scott Telford <st@epcc.ed.ac.uk> provided - a patch for write(1) to make it look more like BSD write. - - Fixed login so that the .hushlogin feature works even with real - protective users mounted via NFS (ie. where root can't access - the user's .hushlogin file). - - Cleaned up the code to make -Wall bearable. - -Version 1.28c (21-Jul-94): - Rik Faith reminded me that agetty should use the syslog - facility. It now does. - -Version 1.28b (30-May-94): - On suggestion from Jeremy Fitzhardinge <jeremy@suite.sw.oz.au> - I added -- as option delimiter on args passed from agetty to - login. Fixes -froot hole for other login programs. The login - program in this package never had that hole. - -Version 1.28a (16-May-94): - bill@goshawk.lanl.gov provided a couple of patches, one fixing - terminal setup in agetty, and reboot is now supposed to be - in /sbin according to FSSTND. - -Version 1.27 (10-May-94): - Changed login.c, so all bad login attempts are logged, and added - usertty security feature. See about.usertty for an explanation. - There's no longer a limit of 20 chars in the TERM environment - variable. Suggested by Nicolai Langfeldt <janl@math.uio.no> - - Added #ifdef HAVE_QUOTA around quota checks. Enable them if - you have quota stuff in your libraries and kernel. - Also re-enabled set/getpriority() calls as we now have them, - and have had for a long time... - - Now wtmp is locked and unlocked around writes to avoid mangling. - Due to Jaakko Hyv{tti <HYVATTI@cc.helsinki.fi>. - - Wrt. agetty: A \o in /etc/issue now inserts the domainname, as - set by domainname(1). Sander van Malssen provided this. - This is being used under Linux 1.1.9 - - Beefed up the agetty.8 man-page to describe the /etc/issue - options. Added man-pages for wall, cage, who. - -Version 1.26 alpha (25-Apr-94): - Added patch from Bill Reynolds <bill@goshawk.lanl.gov> to - simpleinit, so it will drop into single user if /etc/rc - fails, eg. from fsck. - -Version 1.25 (9-Feb-94): - Agetty should now work with the Linux 0.99pl15a kernel. - ECHOCTL and ECHOPRT are no longer set in the termios struct. - Also made agetty accept both "tty baudrate" and "baudrate tty" - arguments. - -Version 1.24 (23-Jan-94): changes since 1.22 - Christian von Roques <roques@juliet.ka.sub.org> provided a patch - that cleans up the handling of the -L option on agetty. - Rik Faith <faith@cs.unc.edu> enhanced several man-pages... - -Version 1.23 (11-Dec-93): changes since 1.21 - Mitchum DSouza provided the hostid(1) code. It needs libc 4.4.4 or - later and a Linux 0.99.14 kernel or later. It can set and print - the world unique hostid of the machine. This may be used in - connection with commercial software licenses. God forbid! - I added the -v option, and munged the code a bit, so don't blame - Mitch if you don't like it. - - I made the "cage" program. Using this as a shell in the passwd - file, enables one to let users log into a chroot'ed environment. - For those that have modem logins and are concerned about security. - Read the source for further info. - - "who am i" now works. - - The login program works with Yellow Pages (aka NIS) simply by - linking with an appropriate library containing a proper version - of getpwnam() and friends. - -Version 1.21 (30-Oct-93): changes since 1.20 - In simpleinit.c: The boottime wtmp record is now written *after* - /etc/rc is run, to put a correct timestamp on it. - Daniel Thumim <dthumim@mit.edu> suggested this fix. - - The source and Makefile is prepared for optional installation of - binaries in /sbin instead of /etc, and logfiles in /usr/adm instead - of /etc. See and change the Makefile to suit your preferences. - Rik Faith and Stephen Tweedie inspired this change. - -Version 1.20 (30-Jul-93): changes since 1.17: - Versions 1.18 and 1.19 were never made publically available. - Agetty now supports a -L switch that makes it force the CLOCAL flag. - This is useful if you have a local terminal attached with a partly - wired serial cable that does not pass on the Carrier Detect signal. - - There's a domainname program like the hostname program; contributed - by Lars Wirzenius. - - Simpleinit will now write a REBOOT record to wtmp on boot up. Time- - zone support is now optional in simpleinit. Both of these patches - were made by Scott Telford <st@epcc.ed.ac.uk>. - - This is for Linux 0.99.11 or later. - -Version 1.17 (19-May-93): changes since 1.16: - Login, simpleinit and write should now work with shadow passwords - too. See the Makefile. Thanks to Anders Buch who let me have an - account on his SLS based Linux box on the Internet, so I could test - this. I should also thank jmorriso@rflab.ee.ubc.ca (John Paul Morrison) - who sent me the shadow patch to login.c - -Version 1.16 (24-Apr-93): changes since 1.15a: - Simpleinit now clears the utmp entry associated with the pid's that - it reaps if there is one. A few are still using simpleinit and this - was a popular demand. It also appends an entry to wtmp - -Version 1.15a (15-Mar-93): changes since 1.13a: - junio@shadow.twinsun.com (Jun Hamano) sent me a one-line fix - for occasional mangled issue-output from agetty. - -Version 1.13a (2-Mar-93): changes since 1.12a: - With the new LILO (0.9), there are more than one possible arg - to init, so Werner Almesberger <almesber@bernina.ethz.ch> - suggested that a loop over argv[] was made in boot_single() in - simpleinit.c - -Version 1.12a (24-Feb-93): changes since 1.11: - This is for Linux 0.99.6 or later. Built with gcc 2.3.3 and libc4.2 - jrs@world.std.com (Rick Sladkey) told me that the setenv("TZ",..) - in login.c did more harm than good, so I commented it out. - -Version 1.11a (16-Feb-93): changes since 1.9a: - This is for Linux 0.99.5 or later. - Anthony Rumble <arumble@extro.ucc.su.OZ.AU> made me avare that - the patches for vhangup() from Steven S. Dick didn't quite work, - so I changed it. - - Linus Torvalds provided another patch relating to vhangup, since - in newer Linuxen vhangup() doesn't really close all files, so we - can't just open the tty's again. - -Version 1.9a (18-Jan-93): changes since 1.8a: - Rick Faith sent me man-pages for most of the untilities in this - package. They are now included. - - Steven S. Dick <ssd@nevets.oau.org> sent me a patch for login.c - so DTR won't drop during vhangup() on a modemline. - - This is completely untested!! I haven't even had the time to - compile it yet. - -Version 1.8a (13-Dec-92): changes since 1.7: - This is for Linux 0.98.6 or later. Compiles with gcc2.2.2d7 and libc4.1 - - Bettered write/wall after fix from I forget who. Now wall can have - commandline args. - - Fixed bug in who.c - - Patched simpleinit.c with patch from Ed Carp, so it sets the timezone - from /etc/TZ. Should probably by be /etc/timezone. - - Sander Van Malssen <sander@kozmix.hacktic.nl> provided a patch - for getty, so it can understand certain escapecodes in /etc/issue. - - I hacked up a very simple substitute for a syslog() call, to try out - the logging. If you have a real syslog() and syslogd then use that! - - The special vhangup.c file is out, it's in the official libc by now. - (and even in the libc that I have :-) - - who, and write are now deprecated, get the better ones from one of - the GNU packages, shellutils I think. - - Some people think that the simple init provided in this package is too - spartan, if you think the same, then get the SYSV compatible init - from Miquel van Smoorenburg <miquels@maestro.htsa.aha.nl> - Simpleinit will probably be deprecated in the future. - -Version 1.7: 26-Oct-92 changes since 1.6: - This is for Linux 0.97PL4 or later. - - Thanks to Werner Almesberger, init now has support for a - singleuser mode. - - Login now supports the -h <hostname> option, used in connection - with TCP/IP. (rlogin/telnet) - - Getty writes an entry to /etc/wtmp when started, so last won't report - "still logged in" for tty's that have not been logged into since - the last user of that tty logged out. This patch was inspired by - Mitchum DSouza. To gain the full benefit of this, get the newest - last from the admutils-1.4.tar.Z package or later. - -Version 1.6 (29-Aug-92): changes since 1.5: - This is for Linux 0.97P1+ or later. - - Login now uses the newly implemented vhangup() sys-call, to prevent - snooping on the tty. - An alternative getpass() function is now provided with login, because - I was told that the old one in libc didn't work with telnet and - or rlogin. I don't have a network or a kernel with TCP/IP so I haven't - tested the new one with telnet, but it is derived from BSD sources - that are supposed to work with networking. - -Version 1.5 (12-Aug-92): changes since 1.4 - This is for Linux 0.97 or later, and has been built with gcc2.2.2 - - This release just puts in a few bugfixes in login.c and simpleinit.c - -Version 1.4 (4-Jul-92): changes since 1.3: - This is for Linux 0.96b, and has been built and tested with gcc 2.2.2. - - Init now handles the SIGINT signal. When init gets a SIGINT it will - call /usr/bin/reboot and thereby gently reboot the machine. This - makes sense because after Linux 0.96B-PL1 the key-combination - Ctrl-Alt-Del may send a SIGINT to init instead of booting the - machine the hard way without syncing or anything. - - You may want to get the admutils-1.1 package which includes a program - that will instruct the kernel to use the "gentle-reboot" procedure. - -Version 1.3 (14-Jun-92): changes since 1.2: - This is for Linux 0.96A. - - The ioctl(TIOCSWINSZ) has been removed from login.c because it now - works :-). - - login.c now supports a lastlog database. - - Several programs and pieces of source that were included in the 1.2 - package has been *removed* as they are incorporated into the new - libc. Other omitted parts such as last(1) has been replaced by - better versions, and can be found in the admutils package. - - Agetty is now called getty and will be placed in /etc. - - A few changes has been made to make it possible to compile the - stuff with GCC 2.x. - -Version 1.2 (28-Feb-92): changes since 1.1: - This is for Linux 0.12. - - A couple of problems with simpleinit.c has been solved, thanks to - Humberto Zuazaga. So now init groks comments in /etc/inittab, and - handles the HUP and TSTP signals properly. - - I added two small scripts to the distribution: users and mesg. - - TERM is now carried through from /etc/inittab all the way to the - shell. Console tty's are special-cased, so the termcap entry in - /etc/inittab is overridden by the setting given at boot-time. - This requires a different patch to the kernel than that distributed - with version 1.1 - - Login no more sends superfluous chars from a password to the - shell. It also properly prints a NL after the password. - - Agetty didn't set the erase character properly, it does now. - - A few extra defines has been added to utmp.h - - Several netters helped discover the bugs in 1.1. Thanks to them - all. - -Version 1.1 (released 19-Feb-92): Changes since 1.0: - A bug in simpleinit.c has been fixed, thanks to Pietro Castelli. - The definition of the ut_line field has been changed to track the - USG standard more closely, we now strip "/dev/" off the front. - Thanks to: Douglas E. Quale and Stephen Gallimore. - - I have added a getlogin.c library routine, and a write(1) command. - I removed the qpl-init stuff. If people want to use it, they should - get it from the source. I don't want to hack on it anymore. - - A couple of people reported problems with getty having problems - with serial terminals. That was correct. I borrowed a null-modem - from Tommy Thorn, and now the problems should be fixed. It seems - that there is kept a lot of garbage in the serial buffers, flush - them and it works like a charm. Getty does an ioctl(0, TCFLSH, 2) - for this. - - The write.c code now doubles as code for a wall(1) program. - -Description of the various files: - -login.c The login program. This is a portation of BSD login, first - to HP-UX 8.0 by Michael Glad (glad@daimi.aau.dk), and - to Linux (initially to 0.12) by me. - -who.c A simple who(1) util. to list utmp. Done by me. - You may prefer the GNU who util. with more options - and features. - -hostname.c A hostname(1) command to get and set the hostname. I did - this too. - -domainname.c Like hostname, only reads out or sets the domainname. - -agetty.c The getty program. From comp.sources.misc, by W.Z. Venema. - Hacked a bit by me. - -simpleinit.c A simple init program, written by me. Uses /etc/inittab - - A "kill -HUP" to init makes it re-read /etc/inittab. - A "kill -TSTP" to init makes it stop spawning gettys on the - ttys. A second "kill -TSTP" starts it again. - A kill -INT to init makes it attempt a reboot of the machine. - this works in connection with kernel support for softboot - when Ctrl-Alt-Del is pressed. - - Init will start up in singleuser mode if /etc/singleboot - exists at boottime, or if it is given an argument of "single" - via eg. LILO. If /etc/securesingle exists it will ask for the - root password before starting single user. - -write.c A write(1) command, used to pass messages between users - at different terminals. This code doubles as code for - a wall(1) command. Make a symlink: /usr/bin/wall -> - /usr/bin/write for this. - -mesg A tiny shellscript, so you can avoid that other people write - to your shell. - -users Another script that uses awk(1) and tr(1) to process the - output from who(1) into a one-liner. - If you don't have awk, but have Perl, this does the same: - - who | perl -ane 'print "$F[0] "'; echo "" - -pathnames.h: - Header. - -param.h - Header, extended with getdtablesize() macro, should go - in /usr/include/sys - -Building. ---------- -A "make all" should do. At least it does for me. - -Installation: -------------- - -login should go in /bin, if you don't like this change - pathnames.h and recompile at least agetty. - -getty, init Put them in SBINDIR - -who, hostname, write, wall, mesg, users: - /usr/bin - -securetty login needs this in /etc, defines which ttys that root - can login on. This should *never* include ttys{1,2} - -inittab the simpleinit code needs this in /etc. Note that the syntax - of /etc/inittab has little to do with the syntax of a real - SysV inittab. Edit this one for your local setup. - -shells The chsh program will use this if it's placed in /etc. It - defines the valid shell-programs. Have one abs. path on - each line. - -You can also do a "make install" as root, but don't just do it because I -say so, check the Makefile first. - -"Make install" will install only the new binaries, and not motd, inittab, -securetty and issue. To install these configuration files, do a -"make Install". - -Getty requires a /dev/console to write errors to. I just made it a symlink -to /dev/tty1. Because of a bug in the tty driver this errorlogging may -cause the shell on tty1 to logout. - -Getty will print the contents of /etc/issue if it's present before asking -for username. Login will print the contents of /etc/motd after successful -login. Login doesn't print /etc/motd, and doesn't check for mail if -~/.hushlogin is present and world readable. - -If /etc/nologin is present then login will print its contents and disallow -any logins except root. -It might be a good idea to have a "rm -f /etc/nologin" line in one's -/etc/rc file. - -If /etc/securetty is present it defines which tty's that root can login on. - - - Peter (poe@daimi.aau.dk) |
