ts3serverARM

I managed to run some x86 applications like the Teamspeak (32 or 64 bit) server on my rpi 3B+ using a virtualized chroot environment (under the 64-bit version of Ubuntu Server for Rpi).

Tested on

Requirements

If the 4.0.0 version isn’t available, on Raspbian you can use Debian’s sid repository && for Ubuntu use eoan or newer repos [you can change the repos by editing your /etc/apt/sources.list file; anyway Google is your best friend ]

Creation of the x86 enviroment

[!note] The i386 architecture is 32-bit. The amd64 architecture is 64-bit. Choose which one you like the most. x64 should be generally faster, mostly due to standardized register usage for function calls.

I will be creating an amd64 environment from now on.

1) Use debootstrap to download the base system in a folder called “./chroot-debian” (folder’s name is up to you - in this case we’ll be downloading Debian stable, you can use others as well): sudo debootstrap --arch amd64 stable ./chroot-debian http://ftp.us.debian.org/debian

2) Copy the qemu amd64 static emulator to the x86 environment’s bin directory:

For QEMU >= v10.0.0: sudo cp /usr/bin/qemu-amd64 ./chroot-debian/usr/bin/

For QEMU < v10.0.0: sudo cp /usr/bin/qemu-amd64-static ./chroot-debian/usr/bin/ 4) Mount the following directories to the x86 environment’s directories (REMEMBER that you need to do this on EVERY system restart):

sudo mount -t sysfs sys ./chroot-debian/sys/
sudo mount -t proc proc ./chroot-debian/proc/
sudo mount --bind /dev ./chroot-debian/dev/
sudo mount --bind /dev/pts ./chroot-debian/dev/pts/
sudo mount --bind /dev/shm ./chroot-debian/dev/shm/

Entering in the x86 environment

1) sudo chroot ./chroot-debian/ 2) cd ~ to return to the default root directory.

Creation of the TS3 server

[!note] Be aware that this environment acts as a parallel user space, so for example, if you need to use a certain program, you need to reinstall it using apt (or whatever its installation method is) in the newly created environment.

[!warning] FROM NOW ON WE ARE INSIDE THE x86 ENVIRONMENT, the commands might take A LOT to run because we are using an emulator inside the Raspberry whose specs aren’t the best in the world. The amd64 architecture should be faster than i386 due to code optimizations.

If Apt asks you to install a package without verification, choose YES.

1) Install debian-keyring, ca-certificates, bzip2, and wget packages: apt install debian-keyring ca-certificates bzip2 wget 2) Download the Teamspeak3 (32bit or 64bit version depending on your environment) server using wget: wget https://files.teamspeak-services.com/releases/server/3.13.7/teamspeak3-server_linux_amd64-3.13.7.tar.bz2 (you can find the latest versions here) 3) Extract the downloaded archive: tar -xvf teamspeak3-server_linux_amd64-3.13.7.tar.bz2 4) Enter the folder: cd teamspeak3-server_linux_amd64 5) Accept Teamspeak’s license by using the file method: touch .ts3server_license_accepted (the touch command creates a file named .ts3server_license_accepted)

First run of the server

1) Run ./ts3server_minimal_runscript.sh (the ts3 server needs to compute a security puzzle at every start without signaling it on the console, so have patience) 2) Copy the created Server Admin token and enter it when connecting to the server 3) yay, Connected!

[well if you have problems open an issue]

Running the server in background

from the base system use screen: apt install screen

sudo screen -dm sudo chroot ./chroot-debian/ /root/teamspeak3-server_linux_amd64/ts3server_minimal_runscript.sh

To kill a screen instance, this is its documentation.

Running the server automatically on boot

To accomplish this I created a systemd service in the following way:

Create a new service file: sudo nano /etc/systemd/system/teamspeak3.service.

Copy the following text into the service file:

[Unit]
Description=Teamspeak Qemu Server
After=syslog.target network.target

[Service]
Type=simple
User=root
Group=root
WorkingDirectory=/home/gabboxl/chroot-debian/
ExecStartPre=-sudo mount -t sysfs sys ./sys/ ; -sudo mount -t proc proc ./proc/ ; -sudo mount --bind /dev ./dev/ ; -sudo mount --bind /dev/pts ./dev/pts/ ; -sudo mount --bind /dev/shm ./dev/shm/
ExecStart=chroot . /root/teamspeak3-server_linux_amd64/ts3server_minimal_runscript.sh
ExecStop=chroot . /root/teamspeak3-server_linux_amd64/ts3server_startscript.sh stop
ExecReload=chroot . /root/teamspeak3-server_linux_amd64/ts3server_startscript.sh restart

[Install]
WantedBy=multi-user.target

Then modify WorkingDirectory’s value so that it points to the folder where the chroot environment is located.

Run sudo systemctl enable teamspeak3 to enable the service, and sudo systemctl start teamspeak3 to start the server.

You’re done!

Final considerations & known issues

~- When someone connects to the server, most probably it will spam Unsupported ancillary data: 0/8 or similar text in the console. I didn’t encounter any problem with server functionalities but at the time I didn’t find a fix for that.
