sessreg

manage utmpx/wtmpx entries for non-init clients

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

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.

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 

-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.
