These are the source files for building the MMDVMHost, the program that interfaces to the MMDVM or DVMega on the one side, and a suitable network on the other. It supports D-Star, DMR, P25 Phase 1, and System Fusion.
|
||||
|
||||
On the D-Star side the MMDVMHost interfaces with the ircDDB Gateway, on DMR it can connect to BrandMeister, DMR+, or HB Link, on System Fusion it connects to the YSF Gateway. On P25 it connects to the P25 Gateway.

On the D-Star side the MMDVMHost interfaces with the ircDDB Gateway, on DMR it can connect to BrandMeister, DMR+, HB Link, XLX or [DMRGateway](https://github.com/g4klx/DMRGateway) (to connect to multiple DMR networks at once) on System Fusion it connects to the YSF Gateway. On P25 it connects to the P25 Gateway.

Linux Daemon Startup Scripts
|
||||
============================
|
||||
# Linux Scripts
|
||||
|
||||
This directory (and its sub-directories) contain various third-party Linux shell scripts that have been written to provide certain system administration functions.
|
||||
|
||||
These are:
|
||||
|
||||
### DMRIDUpdate.sh (and DMRIDUpdateBM.sh)
|
||||
|
||||
Updates the DMRIds.dat file periodically from a cron job.
|
||||
The only difference between the two scripts is the source of the data.
|
||||
|
||||
### tg_shutdown.sh
|
||||
|
||||
Automated shutdown on receipt of a specific talkgroup.
|
||||
The script relies on at least a file loglevel of 2.

# Daemon Startup Scripts

systemd or init for their boot.

These have been writting specifically for Raspbian Wheezy (init) and Rasbian Jessie (systemd) although there is

no reason that they shouldnt work on many other distributions.
