Hi,

I'm having a strange issue with systemd startup.

We run our Xymon as a user called hobbit. If I Start Xymon using the runclient.sh script as hobbit (i.e. /xymon/client/runclient.sh start) then all works perfectly. If I run it using systemctl start xymon a ps -eaf command clearly shows it running as hobbit but Iget the following in my /xymon/client/logs/xymonclient.log file

2020-05-19 14:28:13 Whoops ! Failed to send message (Connection failed) 2020-05-19 14:28:13 -> connect to Xymon daemon at xymonserver:1984 failed (Permission denied) 2020-05-19 14:28:13 -> Recipient 'xymonserver', timeout 15 2020-05-19 14:28:13 -> 1st line: 'client xymonclient.linux linux'

If I test the connection all works OK

My /usr/lib/sysemd/system/xymon.service file is

[Unit] Description=Xymon systems and network monitor Documentation=man:xymon(7) man:xymonlaunch(8) man:xymon(1) After=network.target

[Install]

Compatibility with "xymon" and "xymon-client"

Alias=xymon.service Alias=xymon-client.service WantedBy=multi-user.target

[Service] EnvironmentFile=/etc/sysconfig/xymonlaunch User=hobbit

We wrap in xymoncmd to eliminate the need for the bulk of the old init

script ExecStart=/xymon/client/bin/xymonlaunch --config=/xymon/client/etc/clientlaunch.cfg --log=/xymon/client/logs/clientlaunch.log --pidfile=/xymon/client/ logs/clientlaunch.pid ExecStop=kill cat /xymon/client/logs/clientlaunch.pid PIDFile=/xymon/client/logs/clientlaunch.pid Type=simple User=hobbit

Kill xymonlaunch, but don't send kills to the underlying procs, since they

might be doing important things (like writing checkpoints and flushing

caches) KillMode=process SendSIGHUP=yes SendSIGKILL=yes

and my /etc/sysconfig/launch looks like this

MACHINEDOTS=xymonclient SERVEROSTYPE=linux XYMONOSSCRIPT=xymonclient-linux.sh XYMONCLIENTHOME=/xymon/client/

I don't understand how it works perfectly when I start it as the user using the normal script yet get's permission denied when running under systemd but still as the same user
