title: Build on Ubuntu/Debian

### Using Meson
|
|
|
|
Install the depedencies for using Meson.
|
|
```bash
|
|
$ sudo apt install python3 python3-pip python3-setuptools python3-wheel ninja-build
|
|
```
|
|
|
|
Install Meson using Python
|
|
```bash
|
|
$ pip3 install --user meson
|
|
```
|
|
|
|
### Making TUN Permanent
|
|
---
|
|
|
|
Write a configuration file for the TUN deivce.
|
|
```bash
|
|
$ sudo sh -c "cat << EOF > /etc/systemd/network/99-open5gs.netdev
|
|
[NetDev]
|
|
Name=ogstun
|
|
Kind=tun
|
|
EOF"
|
|
```
|
|
|
|
Create a TUN device. The interface name will be `ogstun`.
|
|
```bash
|
|
$ sudo systemctl enable systemd-networkd
|
|
$ sudo systemctl restart systemd-networkd
|
|
|
|
$ sudo apt install net-tools
|
|
$ ifconfig ogstun
|
|
ogstun: flags=4241<UP,POINTOPOINT,NOARP,MULTICAST> mtu 1500
|
|
inet6 fe80::e86e:86d8:ea24:f8ee prefixlen 64 scopeid 0x20<link>
|
|
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 500 (UNSPEC)
|
|
RX packets 0 bytes 0 (0.0 B)
|
|
RX errors 0 dropped 0 overruns 0 frame 0
|
|
TX packets 2 bytes 255 (255.0 B)
|
|
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
|
|
```
|
|
|
|
Then, to support IPv6-enabled UEs, you must configure your TUN device to support IPv6.
|
|
|
|
```bash
|
|
$ sysctl -n net.ipv6.conf.ogstun.disable_ipv6
|
|
1
|
|
|
|
$ sudo sh -c "echo 'net.ipv6.conf.ogstun.disable_ipv6=0' > /etc/sysctl.d/30-open5gs.conf"
|
|
$ sudo sysctl -p /etc/sysctl.d/30-open5gs.conf
|
|
|
|
$ sysctl -n net.ipv6.conf.ogstun.disable_ipv6
|
|
0
|
|
```
|
|
|
|
**Note:** If your TUN device already supports IPv6, you can skip this steps above.
|
|

|
|
|
|
|
You are now ready to set the IP address on TUN device.
|
|
|
|
```bash
|
|
$ sudo sh -c "cat << EOF > /etc/systemd/network/99-open5gs.network
|
|
[Match]
|
|
Name=ogstun
|
|
[Network]
|
|
Address=10.45.0.1/16
|
|
Address=2001:db8:cafe::1/48
|
|
EOF"
|
|
```
|
|
|
|
Restart the TUN device
|
|
|
|
```bash
|
|
$ sudo systemctl restart systemd-networkd
|
|
```
|
|
|
|
Make sure it is set up properly.
|
|
|
|
|
|
```bash
|
|
$ ifconfig ogstun
|
|
ogstun: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500
|
|
inet 10.45.0.1 netmask 255.255.0.0 destination 10.45.0.1
|
|
inet6 2001:db8:cafe::1 prefixlen 64 scopeid 0x0<global>
|
|
inet6 fe80::e86e:86d8:ea24:f8ee prefixlen 64 scopeid 0x20<link>
|
|
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 500 (UNSPEC)
|
|
RX packets 0 bytes 0 (0.0 B)
|
|
RX errors 0 dropped 0 overruns 0 frame 0
|
|
TX packets 20 bytes 2019 (2.0 KB)
|
|
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
|
|
```
|
|
|
|
**Note:** On *Linux*, you should run `open5gs-pgwd` first to correctly verify the IP address of TUN device. Otherwise, the TUN device's IP address is not displayed by the [ifconfig](http://net-tools.sourceforge.net/man/ifconfig.8.html) command.
