Problem with IP on OpenBTS-UMTS #15

Open Johne21 opened 6 years ago

Johne21 commented 6 years ago

Hello.

I'm trying to set up a UMTS network with a USRP N210 which has an Ethernet connection with the pc, I already managed to register the sim, however it is not assigned an IP address. Using the sgsn list command I get this:

OpenBTS-UMTS> sgsn list GMM Context: imsi=00101010123456799 ptmsi=0x9a001 tlli=0xc009a001 state=GmmRegisteredNormal age=20 idle=20 UE#1 URNTI=a783 stCELL_FACH IPs=none

and in the OpenBTS console:

17:32.4 UL SM Msg: ActivatePDPContextContextRequest UE#1 URNTI=a783 stCELL_FACH imsi=001010123456799 kbps: 0, ops: 0 configDchPS: UL SF=4 RF=1x9600=9600 pb=16 turbo=1 maxprecoded=3180 tb=8x380=3040 coded=9132

I need to connect the user with an ftp server installed on the same pc. I hope and can help me, thank you

@Johne21 I have OpenBTS-UMTS installed and I am using an N210 just like you, but I have not reached where you have advanced because the SIM card is not registered ... Can you tell me what sim card you use, what program do you use to record the values, and what were the values that you recorded? I used the PySIM and I recorded the SUPMSIM values IMSI and Ki, but when I try to register in the network I can not do it ... Could you advise me something ... regards Peter

peterm2109 commented 6 years ago

when I enter the command "sgsn list" I get this: OpenBTS> sgsn list   GMM Context: imsi = 001010000000021 ptmsi = 0x34001 tlli = 0xc0034001 state = GmmDeregistered age = 0 idle = 702 MS = not_active IPs = none

Johne21 commented 6 years ago

Hi.

We also use pySIM to record the value of the IMSI, but the ki must be decrypted with a program called "Woron Scan" (it takes about 2 hours) because the ki programmed with pySIM is not real. The SIM Card must be compatible with the COMP128 standard, we use Super SIM X-sim. When the user is registered in the base station, when entering "sgsn list", in "age" a different value of 0 appears.

To solve the problem of the IP we installed a DHCP server with subnet 192.168.99.0, however, we are still not sure that it is the best option but it works.

Thanks Johne... I Will try

Hi @Johne21
Finally I was able to authenticate the user in the network, thanks for your help. Now the problem that I have is the same that you had. In which computer interface did you install the DHCP server? on the ethernet interface, or in some virtual interface? regards Peter

Johne21 commented 6 years ago

Lo instalé en el mismo computador, con la intrface wlan0, pero igual puede probar la eth0. en este momento no tengo los archivos conmigo, sin embargo cuando los tenga se los envío.

peterm2109 commented 6 years ago

Muchas gracias @Johne21 . si no es mucha molestia y me lo envías te voy a estar muy agradecido de veras peterm2109@gmail.com salu2 Peter

Keskebeu commented 6 years ago

Do you guys use any internal gpsdo?

peterm2109 commented 6 years ago

not me ... @Keskebeu. what do you use that for?

Keskebeu commented 6 years ago

@peterm2109 Thats a gps disciplined oscillator used to synchronize calls in real time.

peterm2109 commented 6 years ago

@Keskebeu.. Do you think it is necessary to fix this problem that I have? I really have no idea how to use it

Keskebeu commented 6 years ago

Have you tried setting up an ip with asterisk ?

That will not solve your issue

peterm2109 commented 6 years ago

@Keskebeu : Have you tried setting up an ip with asterisk ? ... How can I do that?

Keskebeu commented 6 years ago

Are you trying to connect the registered sim card to (sip) make phone calls?

peterm2109 commented 6 years ago

@Keskebeu ... I have not been able to make calls with two terminals yet because I have only one terminal ... excuse the ignorance ... to make a call between two already registered terminals, do I have to have installed asterisk? I thought that when installing OpenBTS-UMTS and subscriberRegistry it was no longer necessary to install asterisk... Excuse me for asking so much

Johne21 commented 6 years ago

Si es posible hacer llamadas con OpenBTS-UMTS? tenía entendido que no soportaba las codificaciones KASUMI y MILANAGE que se utilizan en una red UMTS. Podrían indicarme si estoy equivocado por favor, y como se pueden hacer.

Johne21 commented 6 years ago

@peterm2109. Todavía no consigo los archivos, podría mmostrarme todo lo quele sale escribiendo config en el OpenBTS-UMTSCLI, y enviarme los archivos iptables.rules, interfaces y el archivo de configuración del servidor DHCP.

peterm2109 commented 6 years ago

@Johne21 ... ahorita cuando llegue a casa lo hago... si no es mucha molestia me pudieras facilitar tu correo para no sobrecargar el foro.. salu2 Peter

@Johne21 ... estuve intercambiando con @Keskebeu y me sugirió que el valor de GGSN.DNS lo cambiara por el DNS primario que muestra la conexión de la computadora donde se está ejecutando el OpenBTS-UMTS... En mi caso como estoy en casa lo cambié para 192.168.1.254 y ya no me arroja el error de antes: 17:32.8 UL_DCCH_MessageType_PR_radioBearerSetupFailure UE#1 URNTI=a783 stCELL_FACH rbid=2 unhooking DCH 8dbacf8 waiting to remove.... removed

Aún no he resuelto que me asigne IP OpenBTS> sgsn list GMM Context: imsi=001010000000026 ptmsi=0x73001 tlli=0xc0073001 state=GmmRegisteredNormal age=622 idle=10 UE#1 URNTI=9014 stCELL_FACH IPs=none.

pero al menos el error que nos daba se me resolvió... ah... esto lo hice con el servidor DHCP deshabiltado... que debe ser que lo tengo mal configurado... cuando puedas me mandas los archivos para ver si lo configuro bien... salu2 Peter
