WD6AWP dvm-project-notes

These notes are things I need to keep track of for the DVM Project. 99.9% of this info was gleaned from the DVM Project Discord Server. The folks on the DVM Discord and GitHub have nothing to do with what I have posted here and they don't support it.

DVMHost Install

Do all this as root or with sudo.

• Grab the latest tarball, install the binaries and example configs:

cd ~
wget https://raw.githubusercontent.com/tsawyer/dvm-project-notes/main/tarball/dvmhost_R04Axx_amd64.tar.gz
tar xzvf dvmhost_R04Axx_amd64.tar.gz -C /opt

• Copy examples:

cd /opt/dvm
cp config.example.yml config.yml
cp rid_acl.example.dat rid_acl.dat
cp talkgroup_rules.example talkgroup_rules.yml

• Create a place for the logs: mkdir /var/log/dvm

• Edit config.yml.

• Edit talkgroup_rules.yml to add and/or remove rules as desired.

• Add udev rules:

cd /etc/udev/rules.d/
wget https://raw.githubusercontent.com/tsawyer/dvm-project-notes/main/config/99_dvmv24.rules

• Reboot to activate these rules: reboot

• Install the service:

cd /etc/systemd/system
wget https://raw.githubusercontent.com/tsawyer/dvm-project-notes/main/config/dvmhost.service
systemctl daemon-reload

• Enable DVMhost to start at system boot: systemctl enable dvmhost.service.
• Start DVMhost: systemctl start dvmhost.service.
• View the DVMHost log: journalctl -S today -u dvmhost -f.
• Add cron to remove logs older than 3 days: crontab -e

0 0 * * * /usr/bin/find /var/log/dvm/* -type f -mtime +3 -delete > /dev/null 2>&1

This completes the install. DVMHost should be running.

DVMHost Troubleshoot

Stop the service and run in foreground and look for errors:

systemctl stop dvmhost
/opt/dvm/bin/dvmhost -f -c /opt/dvm/config.yml

DVMHost Update

This updates the DVMProject amd64 binaries without having to compile it on each server.

• Note: If the tarball was previously downloaded the old tarball will not be overwritten. Instead the new tarball will be saved with a .n extension, where n equales the next higher download. Linux tar will extract the files with the .n extension if told to. For example tar xzvf dvmhost_R04Axx_amd64.tar.gz.1 -C /opt

cd ~
wget https://raw.githubusercontent.com/tsawyer/dvm-project-notes/main/tarball/dvmhost_R04Axx_amd64.tar.gz
tar xzvf dvmhost_R04Axx_amd64.tar.gz -C /opt
systemctl restart dvmhost.service

Tada!

DVM-V24 Firmware

Latest DVM V24 Board firmware is required for DVMHost.
