Ah, sorry, misread the previous post. So over the network there’s an issue. Which explains why you’re not seeing your results in CheckMK. Ok, so let’s check if there may be a permission issue after all. First, let’s see if xinetd is running with the proper permissions:
ps axuwww | grep xinetd
Should return something like this:
root 1488 0.0 0.2 49972 4560 ? Ss 09:34 0:00 /usr/sbin/xinetd -stayalive -dontfork
Then the contents of /etc/xinetd.d/check_mk, should read something like this:
service check_mk
{
type = UNLISTED
port = 6556
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/bin/check_mk_agent
disable = no
}
I’ve stripped out comments and options that are not active.
Also, I noticed that you’re still using an old version of the agent: 2.1.0p1, while 2.1.0p16 is available. It’s a long shot but you could try upgrading it.
