$ mongod --dbpath ./data/db
Setting up TUN device (No persistent after rebooting)
Install TUN/TAP driver
- You can download it from http://tuntaposx.sourceforge.net/
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 & Masquerading
$ sudo sysctl -w net.inet.ip.forwarding=1
$ sudo sh -c "echo 'nat on {en0} from 45.45.0.0/16 to any -> {en0}' > /etc/pf.anchors/org.nextepc"
$ sudo pfctl -e -f /etc/pf.anchors/org.nextepc
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.
$ brew install autoconf automake libtool gnu-sed mongo-c-driver libusrsctp gnutls libgcrypt libidn libyaml pkg-config
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`
Note: On MAC OS X, the compilation check is not supported at this point. {: .notice--danger}
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
.
{: .notice--danger}
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}
