Can't attach UE about open5gs HOT 9 CLOSED

The problem is caused by:

[03/13 12:48:21.805] ERRR: ERROR: in '(fd_cnx_receive(c, &ts, &rcv_data.buffer, &rcv_data.length))' : Connection timed out (fd_init.c:116)

What was happening in the socket for diameter network between MME and HSS?

Could you attach the /var/log/nextepc/hss.log file?

And also, are you changing diameter configuration which is located at /etc/nextepc/freeDiameter/mme.conf and /etc/nextepc/freediameter/hss.conf?

If you are not changing the diameter configuration files, more log might be needed.
For more diameter logging, You need to change the trace level like the followings:

logger:
    file: /home/acetcom/Documents/git/nextepc/install/var/log/nextepc/nextepc.log
    trace:
        app: 1
        s1ap: 1
        nas: 1
        diameter: 30
        gtpv2: 1
        gtp: 1

The configuration(diameter: 30) could be applied in /etc/nextepc/mme.conf and /etc/nextepc/hss.conf.

Thanks!

Hi,

The configuration is the default after installation, I not change nothing. See below the files.

Any helps ?

Good!.

Could you perform the following sequence?

1. Please update logger.trace.diameter:30 in mme.conf and hss.conf as below

logger:
   trace:
      diameter: 30

2. Run the followings.

systemctl restart nextepc-mmed
systemctl restart nextepc-hssd

3. Give us the mme.log and hss.log

We'll try to analyze the problem.

Thanks!

Hi,

Attached nextepc log and configuration, with deep traces.

I appreciate your help

The followings is my log.

However, your hss.log is different with me. 127.0.0.1 try to connect MME diameter.

Are you using docker or VM environment?
Or Is there any other dimaeter application?

We suggest to use an initial Ubuntu machine for the first time.

Thanks!

Im using a virgin Ubuntu 16.04.4 machine, on a virtual machine.
Selinux , iptables and AppArmor are off.
No other application was installed.
Maybe is a bug on the latest version, are you using the latest version ?

from open5gs.

In Windows 7 machine, I've installed VirtualBox. And also, my guest OS is ubuntu 16.04.4. I don't know what is your virtual machine. But I believe it might be a similar approach.

After sudo apt-get install nextepc, the followings are my log file.

So, diameter protocol is correctly setup between MME and HSS.

Thanks!

I got it works mostly of the time, at least after linux reboot.

Was not clear the root cause, maybe /etc/hosts (I did some changes) or the order of the applications starts.

But at the moment I got it working and attach an UE.

The order in which you run mme/hss/sgw/pgw/pcrf is not important. We designed that they work in any order. And it will not be /etc/hosts. We have not set diameter default configuration to work with domain name. In /etc/nextepc/freeDiameter/*.conf, all default settings are set to run at IP address (127.0.0.x) instead of domain name.

We will let you know if we get the good fortune to be in the same situation as you.
Enjoy NextEPC.

Thanks!
