Hello,
whole script.
It kills processes of logged-out users.
On our system it runs every few minutes and works efficient enough.
Maybe not the best solution, but works for us :] We do not allow users
to run own demonized processes.
We use lt...@hardy (ubuntu repo package).
Greetings,
Wojtek
# begin of script
#!/bin/bash
# List users with processes
ps -eo user --no-headers | sort | uniq > procUsers
# List logged-in users
who | awk '{print $1}'| sort | uniq > loginUsers
sdiff -s loginUsers procUsers | awk '{print $2}' > procNoLoginUsers
while read -r USER
do
tempUID=`id -u $USER`
# ndbroot process
if [ $tempUID -eq 65534 ]
then
tempUID=100;
fi
# Processes of users UID >= 1000
if [ $tempUID -ge 1000 ]
then
# SIGTERM
killall -u $USER -s 15
sleep 2
# SIGKILL
killall -u $USER -s 9
fi
done < procNoLoginUsers
rm procUsers
rm loginUsers
rm procNoLoginUsers
# end of script
