### Getting MongoDB
|
|
---
|
|
|

Install MongoDB with package manager.
|
|
```bash
|
|
$ sudo pkg install mongodb
|
|
```
|
|
|
|
Run MongoDB server.
|
|

|
|
$ mkdir -p ./data/db
|

### Setting up TUN device (No persistent after rebooting)
|
|
---
|
|
|
|
Configure the TUN device.
|
|
```bash
|
|
$ sudo ifconfig lo0 alias 127.0.0.2 netmask 255.255.255.255
|
|
$ sudo ifconfig lo0 alias 127.0.0.3 netmask 255.255.255.255
|
|
$ sudo ifconfig lo0 alias 127.0.0.4 netmask 255.255.255.255
|
|
$ sudo ifconfig lo0 alias 127.0.0.5 netmask 255.255.255.255
|
|
```
|
|
|
|
Enable IP forwarding
|
|
```bash
|
|
$ sudo sysctl -w net.inet.ip.forwarding=1
|
|
```
|
|
|
|
**Tip:** The script provided in [$GIT_REPO/support/network/restart.sh](https://github.com/{{ site.github_username }}/nextepc/blob/master/support/network/restart.sh) makes it easy to configure the TUN device as follows:
|
|
`$ sudo ./support/network/restart.sh`

### Building NextEPC
|
|
---
|
|
|
|
Install the depedencies for building the source code.
|
|
```bash
|
|
$ sudo pkg install git gcc bison gsed pkgconf autoconf automake libtool mongo-c-driver gnutls libgcrypt libidn libyaml
|
|
```
|
|
|
|
Git clone with `--recursive` option.
|
|
|
|
```bash
|
|
➜ open5gs git clone --recursive https://github.com/{{ site.github_username }}/nextepc
|
|
```
|
|
|
|
To compile with autotools:
|
|
|
|
```bash
|
|
➜ open5gs cd nextepc
|
|
➜ nextepc git:(master) ✗ autoreconf -iv
|
|
➜ nextepc git:(master) ✗ ./configure --prefix=`pwd`/install
|
|
➜ nextepc git:(master) ✗ make -j `nproc`
|
|
```
|
|
|
|
Check whether the compilation is correct.
|
|
|
|
**Note:** This should require *sudo* due to access `/dev/tun0`.
|
|
{: .notice--danger}
|
|
```bash
|
|
➜ nextepc git:(master) ✗ sudo make check
|
|
```
|
|
|
|
You need to perform **the installation process**.
|
|
```bash
|
|
➜ nextepc git:(master) ✗ make install
|
|
```
|
|
|
|
Check whether the installation is correct.
|
|
|
|
**Note:** This should require *sudo* due to access `/dev/tun0`.
|
|
{: .notice--danger}
|
|
|
|
```bash
|
|
acetcom@nextepc:~/nextepc$ sudo ./test/testcomplex
|
|
s1setup_test : SUCCESS
|
|
attach_test : SUCCESS
|
|
volte_test : SUCCESS
|
|
handover_test : SUCCESS
|
|
All tests passed.
|
|
```
|
|
|
|
**Tip:** You can also check the result of `./test/testcomplex` with a tool that captures packets. If you are running `wireshark`, select the `loopback` interface and set FILTER to `s1ap || gtpv2 || diameter || gtp`. You can see the virtually created packets.

For developers, it provides `nextepc-epcd` daemon that includes both *MME*, *SGW*, *PGW*, *HSS*, and *PCRF*.
|
|
|
|
**Note:** This should require *sudo* due to access `/dev/tun0`.

### Building WebUI of NextEPC
|
|
---
|
|
|
|
[Node.js](https://nodejs.org/) is required to build WebUI of NextEPC
|
|
|
|
```bash
|
|
$ sudo pkg install node
|
|
```
|
|
|
|
Install the dependencies to run WebUI
|
|
|
|
```bash
|
|
➜ nextepc git:(master) ✗ cd webui
|
|
➜ webui git:(master) ✗ npm install
|
|
```
|
|
|
|
The WebUI runs as an [npm](https://www.npmjs.com/) script.
|
|
|
|
```bash
|
|
➜ webui git:(master) ✗ npm run dev
|
|
```
|
