Error in mme deamon about open5gs HOT 21 CLOSED

Thanks for the tips.
My only comment is that parser should be more friendly by telling which line is wrong with a reason.

from open5gs.

Could you send a log & conf file?
The location is as below.

Log file : /var/log/nextepc/mme.log
Conf file : /etc/nextepc/mme.conf

Thanks!

Your configuration file has some problem.

I found my error, thanks for the support. Now it work.
Do you have some tutorial for adding an user and a apn profile??

from open5gs.

If you have installed nextepc through apt-get, you should have a web interface available at http://your-epc-ip:3000/
Default user : admin / pass : 1423 . Add a subscriber there

This sounds crazy, but it is real.
All the parsing errors are caused by tab spaces in the config files.
Replacing tabs by white spaces solved all the config parsing errors.

from open5gs.

YAML forbids tabs. You should use space instead of tab in NextEPC configuration file.

YAML FAQ: Why does YAML forbid tabs?

Tabs have been outlawed since they are treated differently by different editors and tools. And since indentation is so critical to proper interpretation of YAML, this issue is just too tricky to even attempt. Indeed Guido van Rossum of Python has acknowledged that allowing TABs in Python source is a headache for many people and that were he to design Python again, he would forbid them.

from open5gs.

We've added a reason string when YAML parser error is occurred.
Those who have difficulty in this situation can easily see why.

Thanks for your comments!

Please how can i resolve this

Hi @amintgan

I cannot find the above problem if you do not upload your configuration file.
Perhaps, there is a problem in your configuration file.

BTW, your version (v0.3.10) is old.
Use the latest version with the package repository at the following link:
https://open5gs.org/open5gs/docs/guide/01-quickstart/

Thanks!

If you just paste the content of your configuration, I cannot find your problem. Please attach your configuration file.
