| Building nextepc from Sources | <style> .blue { color: blue; } </style> |
This post explains how to compile and install the source code on Debian/Ubuntu based Linux Distribution. {: .blue}
Getting MongoDB
Install MongoDB with package manager.
$ sudo apt update
$ sudo apt install mongodb
$ sudo systemctl start mongodb (if '/usr/bin/mongod' is not running)
Setting up TUN device (No persistent after rebooting)
Create the TUN device with the interface name pgwtun.
$ sudo ip tuntap add name pgwtun mode tun
$ sudo ip addr add 45.45.0.1/16 dev pgwtun
$ sudo ip addr add cafe::1/64 dev pgwtun
$ sudo ip link set pgwtun up
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
{: .notice--info}
Building NextEPC
Install the depedencies for building the source code.
$ sudo apt install autoconf libtool gcc pkg-config git flex bison libsctp-dev libgnutls28-dev libgcrypt-dev libssl-dev libidn11-dev libmongoc-dev libbson-dev libyaml-dev
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.
➜ nextepc git:(master) ✗ make check
Tip: You can also check the result of make check 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}
You need to perform the installation process.
➜ nextepc git:(master) ✗ make install
Configure NextEPC
Note: In the developer environment, all settings can be managed in one place, such as [$INSTALL_PREFIX/install/etc/nextepc/nextepc.conf](https://github.com/{{ site.github_username }}/nextepc/blob/master/support/config/nextepc.conf.in). {: .notice--danger}
Modify [$INSTALL_PREFIX/install/etc/nextepc/nextepc.conf](https://github.com/{{ site.github_username }}/nextepc/blob/master/support/config/nextepc.conf.in) to set the S1AP/GTP-C/GTP-U IP address, PLMN ID, and TAC

Building WebUI of NextEPC
Node.js is required to build WebUI of NextEPC
$ sudo apt install curl
$ curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
$ sudo apt install nodejs
Install the dependencies to run WebUI
➜ nextepc git:(master) ✗ cd webui
➜ webui git:(master) ✗ npm install
The WebUI runs as an npm script.
➜ webui git:(master) ✗ npm run dev
Register Subscriber Information
Connect to http://localhost:3000 and login with admin account.
Username : admin
Password : 1423
Note: You can change the password in Account Menu. {: .notice--info}
To add subscriber information, you can do WebUI operations in the following order:
- Go to
SubscriberMenu. - Click
+Button to add a new subscriber. - Fill the IMSI, security context(K, OPc, AMF), and APN of the subscriber.
- Click
SAVEButton
Tip: This addition immediately affects NextEPC without restaring any daemon. {: .notice--warning}
Adding a route for UE to have internet connectivity
If your phone can connect to internet, you must run the following command in NextEPC-PGW installed host.
### Check IP Tables
$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
### Check NAT Tables
$ sudo iptables -L -t nat
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
### Enable IPv4 Forwarding
$ sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
### Add NAT Rule
$ sudo iptables -t nat -A POSTROUTING -s 45.45.0.0/16 ! -o pgwtun -j MASQUERADE
Note: It is a good condition if you do not have any rules in the IP/NAT tables. If a program such as docker has already set up a rule, you will need to add a rule differently.
Turn on your eNodeB and Phone
- You can see actual traffic through wireshark -- srsenb.pcapng({{ site.url }}{{ site.baseurl }}/assets/pcapng/srsenb.pcapng).
- You can view the log at
$INSTALL_PREFIX/var/log/nextepc/*.log.
Troubleshooting
Debugging tools can help you troubleshoot problems.
-
GDB can be used as below:
➜ nextepc git:(master) ✗ sudo apt install gdb ➜ nextepc git:(master) ✗ ./libtool --mode=execute gdb ./nextepc-epcd -
On Mac OS X, you can use the LLDB.
➜ nextepc git:(master) ✗ ./libtool --mode=execute sudo lldb ./nextepc-epcd
You can use the command line option[-d] to record more logs.
➜ nextepc git:(master) ✗ ./nextepc-epcd -d
