MMDVMHost: unable to open the log file

[alex-v-fraser]

Hello!

I try to install MMDVMHost into Synology Virtual Machine.
First I install Debian 12 (clean install).
Then I make MMDVMHost
I get the same error every time I try to start MMDVMHost: unable to open the log file
I tried to start from bash and as service - the same result.
I tried i386, amd64 - the same error.
My system is:

$ uname -a
Linux mmdvm 6.1.0-25-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.106-3 (2024-08-26) x86_64 GNU/Linux

My config is:
the file /usr/local/sbin/mmdvmhost_service (only changed strings)

# Service Config
DAEMON=MMDVMHost
DAEMON_PATH=/opt/MMDVMHost
CONFIG=/opt/MMDVMHost/MMDVM.ini
DAEMON_OPTS=$CONFIG
PGREP=/usr/bin/pgrep
KILL=/bin/kill
SLEEP=/bin/sleep
USER=root
GROUP=root
LOGDIR=/var/log/pi-star

the file /lib/systemd/system/mmdvmhost.service

[Service]

ExecStop=/usr/local/sbin/mmdvmhost_service stop
ExecReload=/usr/local/sbin/mmdvmhost_service restart

[Install]
WantedBy=multi-user.target

In MMDVM.ini I didn't make any changes in LOG

[Log]
# Logging levels, 0=No logging
DisplayLevel=1
FileLevel=1
FilePath=.
FileRoot=MMDVM
FileRotate=1

Will you help me please?

You need to tell the program where to write the log file. It's specified on the configuration line FIlePath in the [Log] section. Wherever you have it written, you must have write permissions.

@g4klx
I suppose FilePath=. means the directory the program runs from. And it runs as root. What permissions does it require?

[g4klx]

You are right, a single dot means the current directory, whatever that is. If it runs as root then it should be able to write anywhere, but it doesn't seem so. I cannot help with your running environment, you need to ask somewhere that discusses it specifically.
