/* This program is derived from 4.3 BSD software and is
   subject to the copyright notice below.

   The port to HP-UX has been motivated by the incapability
   of 'rlogin'/'rlogind' as per HP-UX 6.5 (and 7.0) to transfer window sizes.

   Changes:

   - General HP-UX portation. Use of facilities not available
   in HP-UX (e.g. setpriority) has been eliminated.
   Utmp/wtmp handling has been ported.

   - The program uses BSD command line options to be used
   in connection with e.g. 'rlogind' i.e. 'new login'.

   - HP features left out:          logging of bad login attempts in /etc/btmp,
   they are sent to syslog

   password expiry

   '*' as login shell, add it if you need it

   - BSD features left out:         quota checks
   password expiry
   analysis of terminal type (tset feature)

   - BSD features thrown in:        Security logging to syslogd.
   This requires you to have a (ported) syslog
   system -- 7.0 comes with syslog

   'Lastlog' feature.

   - A lot of nitty gritty details has been adjusted in favour of
   HP-UX, e.g. /etc/securetty, default paths and the environment
   variables assigned by 'login'.

   - We do *nothing* to setup/alter tty state, under HP-UX this is
   to be done by getty/rlogind/telnetd/some one else.

   1991-09-24 glad@daimi.aau.dk: HP-UX 8.0 port:
   - now explictly sets non-blocking mode on descriptors
   - strcasecmp is now part of HP-UX
   1992-02-05 poe@daimi.aau.dk: Ported the stuff to Linux 0.12
   From 1992 till now (1995) this code for Linux has been maintained at
   ftp.daimi.aau.dk:/pub/linux/poe/
