3.3. 手工編譯安裝 MMDVM
上一頁 第 3 章 MMDVM (Multi-Mode Digital Voice Modem)  

3.3. 手工編譯安裝 MMDVM

MMDVM != Pi-Star

說起MMDVM大家就會想到Pi-Star，但是 MMDVM 不等於 Pi-Star。MMDVM是一套獨立系統，Pi-Star 是一套封裝好的MMDVM套件(包含了 MMDVMHost , Dashboard 等軟件)。

首先你需要

事實上，我們可以單獨部署 MMDVMHost，目前已知 MMDVMHost 可以運行在 Linux，Mac OS，Windows系統上。

3.3.1. 創建 MMDVM 用戶

創建 mmdvm 用戶，添加 mmdvm 用戶到 dialout 組

		
useradd mmdvm -s /sbin/nologin
usermod mmdvm -G dialout

因為 /dev/ttyAMA0 和 /dev/ttyUSB0 設備檔案，需要設置成 dialout 組的用戶才能訪問。

		
pi-star@netkiller(ro):~$ ls -l /dev/ttyAMA0
crw-rw---- 1 root dialout 204, 64 Nov 16 22:17 /dev/ttyAMA0
		
neo@netkiller ~ % ll /dev/ttyUSB0 
crw-rw---- 1 root dialout 188, 0 Nov 16 21:40 /dev/ttyUSB0

如果你想使用費 dialout 用戶訪問，可以這樣設置

		
neo@netkiller ~ % sudo chmod o+rw /dev/ttyUSB0
neo@netkiller ~ % ll /dev/ttyUSB0
crw-rw-rw- 1 root dialout 188, 0 Nov 16 21:40 /dev/ttyUSB0

3.3.2. YSFClients

因為 MMDVMHost 需要連接到 YSFGateway 才能工作。所以我們先安裝 YSFGateway。

		
git clone https://github.com/g4klx/YSFClients.git

3.3.2.1. YSFGateway

編譯安裝 YSFGateway

			
cd YSFClients/YSFGateway
make
sudo cp YSFGateway /srv/mmdvm/bin
sudo cp YSFGateway.ini /srv/mmdvm/etc
sudo cp FCSRooms.txt  YSFHosts.txt /srv/mmdvm/etc

sudo cp YSFHostsupdate.sh /srv/mmdvm/bin
sudo chmod +x /srv/mmdvm/bin/YSFHostsupdate.sh

查找中國反射器

			
neo@netkiller /tmp % cat /srv/mmdvm/etc/YSFHosts.txt | grep China
80337;CN China #1;W24166/TG46001;120.234.41.144;42000;044;http://ysf.sz790.com:8081/
82442;CN China #2;W24269/TG46072;116.6.107.115;42006;000;http://ufozhuzi.tpddns.cn:8081/
86319;CN China #3;C4FM;123.58.6.137;42000;002;http://123.58.6.137:8088/
08408;CN CN-China-4;P25;47.105.33.47;42003;001;http://www.bg3hbr.cn/xiuno

YSFHosts.txt 需要定時更新，使用 YSFHostsupdate.sh 腳本，需要簡單配置一下

			
sudo vim /srv/mmdvm/bin/YSFHostsupdate.sh 

# Full path to YSFHosts
YSFHOSTS=/path/to/YSFHosts.txt
改為
YSFHOSTS=/srv/mmdvm/etc/YSFHosts.txt

也可以在 crontab 中更新

			
# sudo crontab -e
*/5 * * * * wget -O /srv/mmdvm/etc/YSFHosts.txt http://register.ysfreflector.de/export_csv.php
