IMSI unknow in HSS about open5gs HOT 44 CLOSED

Did you add a subscriber(IMSI=208930000000003) information?

Please, check the WebUI manual.

Thanks!

from open5gs.

Thanks I fill IMSI and new question happen.

How to solve this question ? Thanks

from open5gs.

The above warning has no problem. I'm hoping that your phone connects to LTE network.
However, if you have some problem, could you give me a wireshark packet capture file?

from open5gs.

put on google drive
https://drive.google.com/open?id=1hyu0EQBbwU7M80HpbWH4yQsazlJRNix0
file name is Authentication failure.pcapng
Enb ip 192.188.2.1

Thanks

from open5gs.

I've checked wireshark file.

Attach Success -> Idle-mode by UE Context Release Request -> Service Request

However, MME didn't send Initial Context Setup Request.
So, the reason is why eNodeB sends S1 Reset message after sending Service Request.

Probably, I need to see MME log.

    trace:
        app: 5
        s1ap: 5
        nas: 5
        diameter: 5
        gtpv2: 5
        gtp: 1

You can change the trace level from 1 to 5 in the configuration file?
And then, please give me a log file to me.

Thanks!

from open5gs.

Sorry how to change configuration file ? Where ?
And where is MME log?

Cant connect to Internet now.

This is correct packet capture file

It is correct! From the capture file and log file, I think that there is no problem.

Thanks!

But I cant connect to internate
looks bad

from open5gs.

For internet connection, you need to setup TAP/TUN driver.

For setting TUN device.

sudo ip tuntap add name pgwtun mode tun
sudo ip addr add 45.45.0.1/16 dev pgwtun
sudo ip addr add cafe::1/16 dev pgwtun
sudo ip link set pgwtun up

If you are succeeding TUN deivce, the result are as below.

ifconfig pgwtun
pgwtun    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00

          inet6 addr: cafe::1/64 Scope:Global
          ...

Moreover, you need to set your network based on our guide document

Nevertheless, if you cannot connect to internet, please give me a log with 'gtp' to 5.

  trace:

Note that gtp log is for data traffic. So, a log of log data will be filled in the log file.

Hmm... TUN setting is good. The remained issue may be IP routing.

If you want to use another method, see the #11
Let me attach eric80s's iptable setting as below.

My host is ubuntu16.04.3, the firewall is enabled, so I added the following few rules:
echo 1 > /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A POSTROUTING -o enp0s31f6 -j MASQUERADE
iptables -I INPUT -i pgwtun -j ACCEPT

Then, the UE can access the internet via 4G.

from open5gs.

Thank you very much.
I will try it tomorrow.

from open5gs.

Good luck with you!

from open5gs.

sudo ip route add 45.45.0.0/16 via 140.113.216.55
RTNETLINK answers: File exists

Its this correct?

from open5gs.

Where are you running this command? EPC Installed machine or the external router(which is connected with EPC).

You should execute this command on the external router. And also, this command grammar could be different with the external router.

However, eric80s’s command(#11) should be executed in the EPC installed host.

from open5gs.

running on EPC Installed machine.
I dont have external router.

about eric80s’s command :
pan@pan:/nextepc-master$ echo 1 > /proc/sys/net/ipv4/ip_forward
bash: /proc/sys/net/ipv4/ip_forward: Permission denied
pan@pan:/nextepc-master$ sudo echo 1 > /proc/sys/net/ipv4/ip_forward
bash: /proc/sys/net/ipv4/ip_forward: Permission denied

from open5gs.

Could you tell me your linux distribution(e.g ubutun 16.04, or fedora,..) for EPC installed machine?

Tomorrow, let me provide the exact command for iptable and sysctl.

Thanks!

thanks a lot

from open5gs.

Here is our suggestions for your EPC-installed Ubuntu.

• Enable ipv4 forward

$ sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

• Enable masquerading
  (Make sure that your enp4s2(140.113.216.55) interface is connected to internet)

$ sudo iptables -t nat -A POSTROUTING -o enp4s2 -j MASQUERADE
$ sudo iptables -I INPUT -i pgwtun -j ACCEPT

Sorry...Please remove '.' after ACCEPT

Sorry still cant connect to internet.

Probably, I need some time to analyze it.

No problem thank you.Take it easy.
I try to use another eNB( still cant connect to internet) . Maybe it will help you.

another_eNB.zip

from open5gs.

In the first eNB(192.188.2.2).It can send something out but cant receive data from Internet.

from open5gs.

From your log, you may want to use 192.168.2.2 for SGW IP address.

However, MME sends SGW GTP-U IP address(141.113.216.55) to eNB because NextEPC sends first detected IP address to the eNodeB.

GTP Protocol Stack cannot send multiple IP address to peer. So, we are just selecting first detect IP address for SGW GTP-U IP Address.

Does eNodeB can send packet to the 141.113.216.55? OR Is it only possible to send 192.168.2.2?
If 192.168.2.2 is communicated with eNodeB, you may need to change SGW GTP-U address statically.

Please, change the configuration file(nextepc.conf) like the following.

• BEFORE

sgw:
     gtpc:
        addr: 127.0.0.2

### if Black, GTP-U Auto Detected ###
     gtpu:

• AFTER

sgw:
     gtpc:
        addr: 127.0.0.2
     gtpu:
        addr: 192.168.2.2

Regardless of the result, we may need to update the IP connectivity guide. We missed multiple interface for SGW GTP-U address.

from open5gs.

Thanks a lot.
I can connect to Internet.

from open5gs.

Wow! Great!
That sounds good to me!

Thanks!

from open5gs.

If I want to run MME HSS SGW PGW on different machine.
Is that capable to do this ? What should I modify?
Thank you

from open5gs.

Basically, nextepc-epcd is a just handy tool for developer. You need to execute nextepc-mmed, nextepc-sgwd, nextepc-pgwd, nextepc-hssd, nextepc-pcrfd on different machine.

• Fix the configuration files based on your network.

etc/nextepc/freeDiameter/hss.conf
etc/nextepc/freeDiameter/mme.conf
etc/nextepc/freeDiameter/pcrf.conf
etc/nextepc/freeDiameter/pgw.conf
etc/nextepc/hss.conf
etc/nextepc/mme.conf
etc/nextepc/pcrf.conf
etc/nextepc/pgw.conf
etc/nextepc/sgw.conf

• Run the following commands in each machine.

./nextepc-mmed -f install/etc/nextepc/mme.conf
./nextepc-sgwd -f install/etc/nextepc/sgw.conf
./nextepc-pgwd -f install/etc/nextepc/pgw.conf
./nextepc-hssd -f install/etc/nextepc/hss.conf
./nextepc-pcrfd -f install/etc/nextepc/pcrf.conf

Thanks!

from open5gs.

When service request , it cant connect to internet again why?

service_request_error.zip

from open5gs.

Oops! there is a significant problem in nextepc-sgwd process.

Null pointer is accessed during paging process. We fixed it.

Please, re-compile your source code after git pull
See the build guide for updating newly source codes.

Thank you for your comment.

from open5gs.

Ya I can connect internet again ,when service request happen.
Are you a company or college ? You fix so quickly.

Thank you.

from open5gs.

Good news!

About us? We will establish a company. Please contact a representative for more information.

Thanks!

from open5gs.

If I want to install MME HSS SGW PGW PCRF on different virtual machine(like VMware Workstation) , the building step is all the same as Ubuntu (http://nextepc.org/docs/build/5-ubuntu/) ?
Or can you write a documentation about install and configurate about MME HSS SGW PGW PCRF on different virtual machine.

Thanks!

from open5gs.

We do not have the proper documentation related to install on another machine. The only guide is the contents of the configuration file(nextepc.conf). You will need to refer to this and configure IP address.

Anyway, http://nextepc.org/docs/build/5-ubuntu/ is for Old Ubuntu Version such like trusty. If you are using xenial(current LTS version) or artful, you need to check the http://nextepc.org/guides/2-build/.

Good luck with you!

Hi, chengYingHsieh

Authentication failure(MAC failure) means that UE-EPC authentication is failed.
Please, check K, OPc, AMF value between USIM and NextEPC.
It can be configured with Web User Interface in NextEPC.
