Run MongoDB server.
$ mkdir -p ./data/db
$ mongod --dbpath ./data/db
Setting up TUN device (No persistent after rebooting)
Configure the TUN device.
$ 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
$ 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.
$ sudo pkg install git gcc bison gsed pkgconf autoconf automake libtool mongo-c-driver gnutls libgcrypt libidn libyaml
Git clone with --recursive option.
➜ open5gs git clone --recursive https://github.com/{{ site.github_username }}/nextepc
To compile with autotools:
➜ 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}
➜ nextepc git:(master) ✗ sudo make check
You need to perform the installation process.
➜ nextepc git:(master) ✗ make install
Check whether the installation is correct.
Note: This should require sudo due to access /dev/tun0.

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. testcomplex.pcapng({{ site.url }}{{ site.baseurl }}/assets/pcapng/testcomplex.pcapng)
{: .notice--info}
