sessreg(1)


NAME

   sessreg - manage utmpx/wtmpx entries for non-init clients

SYNOPSIS

   sessreg  [-w  wtmpx-file]  [-u  utmpx-file] [-L lastlog-file] [-l line-
   name] [-h host-name] [-s slot-number] [-x Xservers-file] [-t ttys-file]
   [-V] [-a] [-d] user-name

DESCRIPTION

   Sessreg  is  a  simple  program  for  managing  utmpx/wtmpx and lastlog
   entries for xdm sessions.

   This version of sessreg is built using the modern POSIX  pututxline(3c)
   interfaces,  which  no  longer  require  the slot-number, ttys-file, or
   Xservers-file mappings.  For  compatibility  with  older  versions  and
   other  operating  systems,  the  -s, -t, and -x flags are accepted, but
   ignored.

USAGE

   In Xstartup, place a call like:

          sessreg -a -l $DISPLAY -x /etc/X11/xdm/Xservers $USER

   and in Xreset:

          sessreg -d -l $DISPLAY -x /etc/X11/xdm/Xservers $USER

OPTIONS

   -w wtmpx-file
          This   specifies   an   alternate   wtmpx   file,   instead   of
          /var/log/wtmp.  The special name "none" disables writing records
          to the wtmpx file.

   -u utmpx-file
          This   specifies   an   alternate   utmpx   file,   instead   of
          /var/run/utmp.  The special name "none" disables writing records
          to the utmpx file.

   -L lastlog-file
          This  specifies  an   alternate   lastlog   file,   instead   of
          /var/log/lastlog,  if  the platform supports lastlog files.  The
          special name "none" disables  writing  records  to  the  lastlog
          file.

   -l line-name
          This  describes  the  "line"  name  of  the entry.  For terminal
          sessions, this is the final pathname  segment  of  the  terminal
          device  filename  (e.g.  ttyd0).   For  X  sessions,  it  should
          probably be the local display name given to  the  users  session
          (e.g.  :0).   If  none  is  specified, the terminal name will be
          determined with ttyname(3) and stripped of leading components.

   -h host-name
          This is set to indicate that the session was  initiated  from  a
          remote host.  In typical xdm usage, this options is not used.

   -s slot-number
          This  option  is accepted for compatibility, but does nothing in
          this version of sessreg.

   -x Xservers-file
          This option is accepted for compatibility, but does  nothing  in
          this version of sessreg.

   -t ttys-file
          This  option  is accepted for compatibility, but does nothing in
          this version of sessreg.

   -V     This option causes the command to print its version and exit.

   -a     This session should be added to utmpx/wtmpx.

   -d     This session should be deleted from utmpx/wtmpx.  One  of  -a/-d
          must be specified.
