Hi all,Is there some special routine for enabling ssh on nano 3gs8 device?Or is the unit "useless" if the ssh-daemon is not running?(I have no way of seeing whether or not it is running)
I can access by telnet to dmi interface, the telnet commands from the wiki are present and have read the docs from accelerate 3g but I think there might be some subtle info I miss regarding starting ssh.
Port 22 is blocked is the errror message I get and i also tested the aes-method suggested in the wiki, same error, port 22 blocked also in that case.
Could this be the situation where one has to try setting up a tr069 server?

Hello fellow telecom hackers,
Seeing that OsmoDevCon 2022 is being discussed, I would like to propose
a more inclusive alternative, to be held in either USA or Mexico.
There are two severe lack-of-inclusion problems with OsmoDevCon:
1) Since its very beginning, ODC has been exclusionary, limited only
to Osmocom developers specifically, excluding those developers and
tinkerers who work on non-Osmocom projects in the "indie" telecom
space, "indie" being defined as independent of major commercial
vendors and industry. I hold the opinion that all monocultures are
bad in principle, and an Osmocom monoculture is no better than, say,
a Microsoft monoculture. Osmocom is currently in the dominant
position, outweighing all others by some orders of magnitude, but
might does not make right, and we need more diversity. We need more
players in this niche space than just Osmocom!
2) The recent decision to limit OsmoDevCon only to those who have
agreed to put a certain class of pharmaceutical into their bodies,
*on top* of the Osmocom-only restriction of the previous paragraph,
makes the proposed conference even more exclusionary and therefore of
no service to the wider telecom hacker community.
Of course it is not my place as a Russian-American to try to tell EU
countries whom to allow or not allow within their borders, nor is it
my place to tell private individuals like our Fearless Leader Harald
whom to allow or not allow in their private spaces. But what I *can*
do instead is to step forward and offer to organize and host a more
inclusive alternative, and that is what I am doing with this post.
Specifically I am offering to organize and host a physical in-person
gathering of telecom (all telecom, not just wireless) hackers,
enthusiasts and tinkerers, very similar in spirit to OsmoDevCon, but
more inclusive:
1) Welcoming everyone who has devoted a major portion of his or her
life to *any* project in the indie telecom space, regardless of which
domain that project is hosted under, and regardless of whether that
project is FOSS or merely PSS. (PSS = Published Source Software, a
superset of FOSS.)
2) Welcoming everyone regardless of personal medical choices - what
you do with your body is your business, not mine - you don't tell me
what I should or shouldn't put in my body, and I won't tell you what
you should or shouldn't put into yours. Also no forced testing: if
you wish to get yourself tested for this or that before attending, it
is your sovereign choice to do so, but no one will *ever* be turned
away from an event which I organize and host, neither for refusing to
test nor for any other reason.
If there is anyone interested in such an inclusive in-person gathering
of telecom hackers, I am offering to host one in my part of the world.
Where is it geographically? I live in USA, near San Diego, and right
next to the border between USA and Mexico. Depending on who is
interested in joining and where they will come from, I can host our
InclusiveDevCon on either side of the border, i.e., either in USA or
in Mexico.
It is my understanding that gaining entry into Mexico is much easier
than gaining entry into USA, hence for that reason I suggest that we
hold our get-together on the Mexican side of the border. If we do
choose Mexico as our host country, the specific location will need to
be in the northern part of that country, specifically in the Mexican
state of Baja California; the candidate cities would be Tijuana or
Ensenada, somewhere close to the border with USA. However, if the
only people who are interested in joining either already live in USA
or can easily enter this lovely country, then holding our Inclusive-
DevCon in USA would make more sense - in that case it will be somewhere
in San Diego area.
Alternatively, if there is anyone in the community who shares my stated
values of wider inclusion but cannot or does not wish to travel to USA
or Mexico, if you would be willing to host an inclusive event in your
part of the world, then I will consider traveling to attend your event
- but *only* if your event is open to non-Osmocom PSS developers *and*
open to those who refuse injections. Please note, however, that I
cannot enter Russia - other parts of the former USSR including
Transnistria are potentially accessible to me, but not Russia - I was
born there, but I permanently lost the ability to visit my birthplace
as a result of having done my gender transition while living in USA,
with all steps for legal name and gender change done under the
American system, as opposed to Russian.

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.

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
Vania
