Help, I've found a bug !

Always start by checking your release is up to date. Even if you are reluctant to update your system, you should at least test with a fresh release.

System does not behave as expected

When system does not behave as you expect, it may be due to a misunderstanding of LTE or a bug in our software.
To understand the situation, please open a ticket with the following information at support.amarisoft.com:

• Config files (Ex: config/enb.cfg or config/mme.cfg)
• Log files (Ex: /tmp/enb0.log and /tmp/mme.log)
• Description of your scenario

Note that by default, only few logs are enabled. To improve debug, you should enable logs for relevant layers.
If you are not familiar with that, just enable everything by setting log_options in your config file this way:

Or type in monitor if you don't want it to be persistent:

log all.level=debug,all.max_size=1

Software has crashed

> While using your software, I am facing a crash, what can I do ?

If it is reproducible, we may help you to understand what occurred so that we can find a workaround for you and fix issue for next release.

First, as explained below (System does not behave as expected), provide us with logs, config files and scenario.

When the software crashes, it will generate a core dump.
Depending on your Linux configuration, core dump may have to be enabled, you can do it with the following command as root (not permanent):

If you use Fedora 26 or later, after the crash you can locate the coredump file by typing the following command:

If you use another distribution, the place where your core dump will be generated depend on your Linux distribution.
You can check this with following command:

You can also specify a folder where the core dump should be saved. As a root you run:

mkdir -p /tmp/cores chmod a+rwx /tmp/cores echo "/tmp/cores/core.%e.%p.%h.%t" > /proc/sys/kernel/core_pattern

Whatever happens

If you use LTE automatic service (By default on Callboxes and Simboxes), always send /tmp/lte.log file as it includes plenty of useful information and will speed up our analysis.
