Hello. I am trying to understand why the q2server process starts on reboot, but does not listen to any port.

I checked with 'netstat -anp | grep <PID>'

I set it to auto start on reboot with the following cron entry.

Quote:
#this below command for q2 doesn't work for some reason. The q2server starts but it doesn't listen to on any port
#@reboot /home/ts3/q2server/r1q2ded +set ip 50.116.61.37 +set port 27910 +set dedicated 1 +set game opentdm +exec server.cfg +map q2rdm2 > /dev/null 2>&1 &


With the above entry uncommitted and after the host is rebooted, I immediately see the following process with pid 3664, and ppid 1 (init)
Quote:
ps -ef | grep q2
ts3 3664 1 1 20:31 ? 00:00:21 /home/ts3/q2server/r1q2ded +set ip 50.116.61.37 +set port 27910 +set dedicated 1 +set game opentdm +exec server.cfg +map q2rdm2


However, when I copy and paste the command myself, it starts the server and also is listening on specified port 27910. I noticed the difference that the ppid is not 1 (init).

As you can see the server is starting and listening on the right port. But only when i run the command manually, and the ppid is different.

I expect the command is running before the network comes up. Try adding a sleep in there and see if it helps.

Is there a way to add sleep to the entire cron execution or is it done per line entry ?

Would changing a runlevel of cron from 2 to 3 be a bad idea?

Quote:
chkconfig --list | grep cron
cron 0:off 1:off 2:on 3:on 4:on 5:on 6:off


Quote:
chkconfig --list | grep network
networking 0:off 1:off 2:off 3:off 4:off 5:off 6:off S:on

I got it working using q2server start-up on boot using /etc/init.d/q2-opentdm-tourney3
As you can see in the q2-opentdm-tourney3 script below the start command has --chuid ts3:ts3 which is user:group.
With this in mind q2server runs as the user:group specified, instead of root.

Quote:
etc/init.d# cat q2-opentdm-tourney3
#! /bin/sh
set -e

# start and stop the Quake II servers

test -x /home/ts3/q2server/start-opentdm-tourney3 || exit 0

export PATH="${PATH:+$PATH:}/usr/sbin:/sbin"

case "$1" in
start)
echo -n "Starting Quake II server: opentdm-tourney3"
start-stop-daemon --start --quiet --chuid ts3:ts3 --chdir /home/ts3/q2server --exec /home/ts3/q2server/start-opentdm-tourney3
echo "."
;;

*)
echo "Usage: /etc/init.d/"q2-opentdm-tourney3" {start}"
exit 1
esac

exit 0


Quake 2 server start command is in a shell script start-opentdm-tourney3 below, which is being called by /etc/init.d/q2-opentdm-tourney3 start.

Quote:
cat /home/ts3/q2server/start-opentdm-tourney3
#!/bin/sh
nohup sh -c './r1q2ded +set ip 50.116.61.37 +set port 27910 +set dedicated 1 +set game opentdm +exec server.cfg +map q2rdm2 +set logfile_name tourney3-console.log +set logfile 3 +set logfile_filterlevel 4096 > /dev/null 2>&1 &'


So as a result, q2server starts when I reboot the server and it works as expected.
