Multiple Issues with dlt-daemon.service: System not booted with systemd, Configuration Errors, and Permission Issues
Opened this issue · 1 comments
I am experiencing issues with the dlt-daemon.service on my system. The daemon fails to start correctly, and I receive several errors in the logs. Despite multiple attempts to troubleshoot, the problem persists. Below are the details of the error logs and the steps I have taken so far.
Error Logs:
Steps Taken to Resolve the Issue:
1.Checked the configuration of /lib/systemd/system/dlt-daemon.service and changed the user to dltuser to avoid the nobody user configuration warning.
2.Verified that the system is booted with systemd by running ps -p 1 -o comm= and confirming it returns systemd.
3.Ensured that the /tmp/dltpipes directory exists and has the correct permissions by running:
$sudo mkdir -p /tmp/dltpipes
$sudo chmod 777 /tmp/dltpipes
4.Verified the installed DLT daemon version is 2.18.6 STABLE by running dlt-daemon --version.
5.Created a dedicated user and group dltuser with the following commands:
$sudo useradd -r -s /bin/false dltuser
$sudo groupadd dltuser
$sudo usermod -aG dltuser dltuser
6.Updated the /etc/systemd/system/dlt-daemon.service file:
[Unit]
Description=GENIVI DLT logging daemon
After=network.target
[Service]
ExecStart=/usr/local/bin/dlt-daemon -d
Restart=on-failure
User=dltuser
Group=dltuser
Environment=DLT_DAEMON_IGNORE_SYSTEMD_BOOT=true
[Install]
WantedBy=multi-user.target
7.Started the service and checked its status:
$sudo systemctl daemon-reload
$sudo systemctl enable dlt-daemon.service
$sudo systemctl start dlt-daemon.service
$sudo journalctl -u dlt-daemon.service
System Information:
OS: Ubuntu 22.04.4 LTS x86_64
dlt-daemon Version: 2.18.6 STABLE
I have tried everything to the best of my ability to resolve these errors but have not been successful. Any assistance or guidance on this issue would be greatly appreciated.
Hello @Fiyeovio
2.18.6 is quite an old version.
Have you tested yet with 2.18.10?
