msd_lite

http://www.netlab.linkpc.net/wiki/en:software:msd:lite

Deprecated, but recommended!!! You can also use Multi Stream daemon (msd)

Steps:

1 Clone code on computer, because my ER-4 reports dpkg errors, due to the outdated debian stretch. Then upload to ER-4

git clone --recursive https://github.com/rozhuk-im/msd_lite.git
tar zcvf msd_lite.tar.gz msd_lite
scp msd_lite.tar.gz ubnt@192.168.1.1:/tmp/

2 On ER-4, install build-essential, cmake

For build-essential, read EdgeRouter 4 Build & Install udpxy

# apt install cmake
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 cmake : Depends: cmake-data (= 3.7.2-1) but it is not going to be installed
         Depends: libarchive13 (>= 3.0.4) but it is not going to be installed
         Depends: libjsoncpp1 (>= 1.7.4) but it is not going to be installed
         Depends: libuv1 (>= 1.4.2) but it is not going to be installed
 dpkg-dev : Depends: xz-utils but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).



# apt install cmake cmake-data  libarchive13 libjsoncpp1 libuv1 

3 build on ER-4

tar xvf /tmp/msd_lite.tar.gz
cd msd_lite
mkdir build
cd build
cmake ..
make 
make install

4 configure and run

/etc/msd_lite.conf

I only modified the multicast -> ifName to br0.

RUN

msd_lite -c /etc/msd_lite.conf -v

msd

Same as msd_lite, but powerful.

Please DON’T use udpxy, check msd_lite!!!

Steps:

1 Configure apt source

EdgeOS 2.0 is based on debian stretch, outdated.

# cat /etc/apt/sources.list.d/stretch.list
deb http://archive.debian.org/debian/ stretch main contrib
deb http://archive.debian.org/debian/ stretch-updates main contrib
deb http://archive.debian.org/debian/ stretch-backports main contrib

deb http://archive.debian.org/debian-security/ stretch/updates main

2 install build-essential

apt install build-essential

3 Get source, and build

wget http://gigapxy.com/download/udpxy/udpxy-src.tar.gz
tar xvf udpxy-src.tar.gz
cd udpxy-1.0.25-1/
make

Then you will see error like cc not found.

CC=gcc make

You’ll see

gcc: error trying to exec 'as': execvp: No such file or directory

This is because the binutils package provided by UBNT is almost empty.

wget -c https://archive.debian.org/debian/pool/main/b/binutils/binutils_2.28-5_mips.deb
dpkg --unpack binutils_2.28-5_mips.deb

Backup your config, Install manually.

Then

CC=gcc make
CC=gcc make install
