Operating Systems HP-UX [Solved] How to remove / kill defunct processess? Post 302411070 by jgt on Wednesday 7th of April 2010 01:26:44 PM
Old 04-07-2010
This issue seems to be caused by users closing Windows terminal emulation sessions without first signing off, (clicking on the X before exiting the session.)
On SCO systems, these "ghost" sessions tend to consume all the available CPU trying to re-connect.
I wrote the following script to deal with this issue, but it should be used with caution.
On SCO systems telnet sessions are named ttypnn, on HP-UX it appears they are named pts/nnn.

Code:
#!/bin/ksh
if [ $# -eq 0 ]
then
echo Usage is delete.ghosts  Y or N
exit 1
fi
ps -leaf |grep ttyp >/tmp/ps.list
who >/tmp/user.list
LIST=; export LIST
separator=" "
while read a tty c 
do
LIST=$LIST$separator$tty
separator=" |"
done </tmp/user.list
grep -v "?" </tmp/ps.list |grep -v root |\
grep -E -v "$LIST" >/tmp/ghost.list
while read a b user pid e f
do
if [ $1 = Y ]
then
echo for real $user $pid
echo kill -9 $pid
#kill -9 $pid
else
echo test run $user $pid
echo kill -9 $pid
fi
done </tmp/ghost.list
#

irsend

IRSEND(1)							   User Commands							 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
