Hi all,
Just wanted to share an issue and a quick workaround I found for it in case
anyone else has the same problem. I believe a cmd2 update is causing
pySim-shell to fail. After installing it on a fresh install of Ubuntu
Server 20.04 and getting the following error when I run "python3
pySim-shell -p0":
>Using PC/SC reader interface
>Autodetected card type: sysmoUSIM-SJS1
>AIDs on card:
> USIM: a0000000871002ffffffff8907090000
>Traceback (most recent call last):
> File "pySim-shell.py", line 512, in <module>
> app = PysimApp(card, rs, opts.script)
> File "pySim-shell.py", line 59, in __init__
> super().__init__(persistent_history_file='~/.pysim_shell_history',
allow_cli_args=False, use_ipython=True, auto_load_commands=False,
command_sets=basic_commands, >startup_script=script)
>TypeError: __init__() got an unexpected keyword argument 'use_ipython'
If you run into this you can fix it by uninstalling cmd2 and reinstalling
cmd2 with "pip3 install cmd2==1.5".
Best,
Bryan
Hi,
My name is Brackley Cassinga Form DRC, we run a community network called
pamoja net where we offer gsm services using osmocom open source software
and OC Base station.
Recently I have tried to install another base station as the same installed
but I could not find any resource guiding through all the steps to take to
run NIB on a base station.
I'm currently running Ubuntu and I will appreciate if you could guide me on
the installation of BSC,hlr,MSC , in order to run a basic gsm network.
Thank you. Regards

Hi Osmocom,
I'm trying to integrate the FreeSwitch as my external MNCC in my test lab using split stack. Currently, I'm getting an error message on FreeSwitch SIP/2.0 400 Missing Contact Header. I'm little bit confused with the error and I don't know where to troubleshoot this.
I've attached my osmo configurations and pcap trace for your reference. Hoping for your reply. Thank you.

Hi list,
today I fixed a header file in libosmocore:
https://gerrit.osmocom.org/c/libosmocore/+/26044
TL;DR, using OSMO_IS_{LITTLE,BIG}_ENDIAN macros without including the
<osmocom/core/endian.h> header leads to empty struct definitions, and
thus weird compiler warnings like 'struct `foo` has no member `bar`'.
We may want to catch missing #include of the <endian.h> automatically,
so I wrote a simple script to check whether it is absent:
https://gerrit.osmocom.org/c/osmo-ci/+/26045
Below is an example of using it:
$ cd libosmocore/
$ verify_endian_header.sh $(find . -name "*.[hc]")
File './include/osmocom/gsm/protocol/gsm_44_004.h'
does not #include <osmocom/core/endian.h>
What's still missing is the actual integration into the build
verification process. I guess there is currently no easy way other than
calling this script from 'contrib/jenkins.sh' of each project?
P.S. I found out that we also have 'scripts/verify_log_statements.py' in
osmo-ci.git, but we don't seem to call it anywhere?
Best regards,
Vadim.

Dear All,
I am running a GSM stack:
osmo-stp
smo-msc
osmo-hlr
osmo-bsc
osmo-bts-trx
osmo-trx-lms
It seems that my transmitter is emitting radio-waves into air (osmo-bts-trx and osmo-trx-lms communicate with each other through ports 5702 / 5802 — pls see attached printscreen), however i could not make GSMTAP tracing. Osmo-bts-trx does not send GSMTAP messages to port 4729.
In most recent version of osmo-bts, GSMTAP tracing is arranged through config file:
bts 0
gsmtap-remote-host 127.0.0.1
gsmtap-sapi ccch
I could not run the GSMTAP tracing even in previous verions of osmo-bts where you have to specify in synopsis when you call a program:
/usr/bin/osmo-bts-trx -s -c /etc/osmocom/osmo-bts-trx.cfg --gsmtap-ip 127.0.0.1
I thought may be i am having some issues in stack components behind osmo-bts for example in osmo-bsc or behind and i tried to run virtual bts.
When i tried to run osmo-bts-virtual GSMTAP messages were visible in wireshark (please see attached file osmo-bts-virtual), therefore bts-bsc communication is good.
However I still could not figure out why my osmo-bts-trx does not send GSMTAP messages.
Or would you advise what log might be helpful to see what i am doing wrong ….
Thank you for your always helpful assistance

Dear Osmocom community,
today we finally upgraded our redmine installation from the unmaintained
3.4.x to the latest 4.2.3. The upgrade had been overdue for years,
but today we (actually, Kevin) finally managed to find out how to make
the openid_provider plugin to work with modern rails 5.x.
In any case, I'm just informing you in case there is some unexpected fallout.
I've verified that at least the following appears working:
* logging into redmine
* openid authentication from gerrit.osmocom.org (also after logout/relogin)
* graphviz rendering
* mscgen rendering
There could however still be unexpected problems, particularly in features
such as
* e-mail notifications from redmine
* updating redmine issues via e-mail
* git integration ("Closes: OS#xxxx")
If you run into any troubles, pleas report to https://osmocom.org/projects/osmocom-servers
or if that also fails, feel free to send e-mails.
Regards,
Harald

Not sure if this is a repost, i just joined the list and i don't think i
had confirmed my account when i sent it (the confirmation was in my spam).
Anyways, not trying to be a bad list member.
I just picked up this IPAccess model which supports band 2/5 and has the
same housing as the other units on the accelerate3g5 project docs. I've
been pouring over docs and trying a lot of network configurations in my
home lab. I have the login information for the factory reset and can access
the web gui on port 8089 during the reset process, but ssh and telnet DMI
seem to be disabled. I've been fuzzing ports and i've tried static as well
as DHCP for IP addresses.
My thought was that if i point the nano3G to the IP of my osmo-hNodeB
machine that it would at least stimulate the device and maybe i'd see some
log messages in the HNodeB gateway, but so far i haven't seen anything in
the logs. i've also tried abisip-find and that doesn't find anything.
Wireshark shows basic 'who has' Layer 2 messages and also DHCP requests
sent to 0.0.0.0, both from the nano3g. The nano3g does get an ip from my
lab router and i can ping it. The LAN behind that router can also access
the 0.ipaccess ntp server, but again no telnet DMI or ssh so i'm unsure
where to go from here.
Layer 1 seems to show nothing on the uarfcn in the web gui, so it seems
that its not crossing all the right bridges.
I will admit, i haven't run any other osmo network components for the
network, but as far as i was reading the home nodeb gateway and ntp should
be the only things necessary to at least start the process.
Any insight on what to try next would be very helpful. Does anyone have
experience with this model?
thanks

Hi Osmocom,
May I ask if we have similar feature of auto provisioning of subscribers who are trying to camp to the network similar to auth-policy accept-all in osmo-nitb? Is the new version supports also the auto provisioning of subscribers?

Hello, im Using a default configuration for my osmo-bsc setup using B210. I
managed to get a working amplifier with specifications below.
My question is, what should be the best config that i should use in order
to maximize tge power and range of my amplifier?
What are the best configs for osmo-trx, osmo-bts, and other applications
related to osmo-bsc. Proper settings such as osmotrx tx-attenuation,
nominal power, ms max power and other related configurations that are valid
or matched for my amplifier.
Listed below is my amplifier's specification.
AMPLIFIER SPECS:
band:
uplink 885-915MHz / downlink 930-960MHz
Max output power: downlink 47±1dBm
Max allow input power:
uplink -10dBm / downlink +10dBm
gain:
Uplink 25±2dB
Downlink 28 to 53±1dB
ALC:
Uplink ≥10dB
Downlink ≥10dB
SWR:
Uplink ≤1.5
Downlink ≤1.5
Passband ripple:
Uplink ≤2dB
Downlink ≤2dB
Noise floor:
uplink ≤2dB
third order intermodulation:
Uplink ≤-55dBc@-8dBm/ch/2ch
Downlink ≤-36dBc@2ch
Voltage:

Hello all,
We trying to bring up set of BTS with virtual Um with different configurations:
1 BTS -> 1 TRX -> 1 MS works fine as expected
1 BTS -> 1 TRX -> 2 MS works fine as well
But I see some unpredictable behaviour when I have
1 BTS -> 2 TRX(872,873) -> 1 MS
MS can attach on one ARFCN (872) but when it tries to attach on 873
looks like PRACH does not reach BTS and I do not see Channel Request
on BSC side.
So, the question is it workable configuration:
Several TRX to 1 MS with different power level to allow MS to choose a
best cell to attach?
I have just one idea: to have several virtphy instances for MS
connected to different UDP ports.
Thank you

Hi All,
I was again looking at advancing with LCLS support.
I've made a couple of proposals, which at least get it to the stage
where the global call reference it consistent from the A leg to B leg of
a call, with both the internal mncc and external, and therefore
osmo-bsc can make use of either the lcls-mode (mgw|bts)-loop.
The implementation in the osmo-sip-connector doing nothing more than
passing the GCR from leg to leg, but it's more complicated than this.
We need to allow the PBX to have the audio streams until the PBX itself
decides to remove itself from the stream. (as it is you won't even hear
ringback)
I know all this is spec-ed somewhere in LCLS, I'm just not sure
where/how this SIP re-INVITE processing should be implemented, in the
sip conn, or the MSC - which I guess, takes us back again to neels' long
standing proposals for parsing SDP inside the MSC. Maybe it' s time to
get that merged.
Anyway.. I have some time scheduled to try to move this forward towards
a definitive solution, just writing here in case anyone else can help.
Thanks.
