Hi Goran,
for me all is ok install from that sources, I builded Openbsc, etc on kali
linux just 2 weeks ago from that sources.
maybe its just dependency, you need to put more info for the error and
someone will help more.
regards,
DUO

Hi,
Thank you very much for your response,
This make me believe in this project, I have just found that there are
released Nightly Builds for Osmocom GSM related software. I will
reinstall my server with one of this builds and try everything again, Basically
I was following procedure from Site, on my Debian server but was stucked
with dependencies which I were not able to compile, Libosmo-sccp,
Libosmo-netif, libosmo-abis
*https://osmocom.org/projects/cellular-infrastructure/wiki/Build_from_Source*
<https://osmocom.org/projects/cellular-infrastructure/wiki/Build_from_Source> I
will come back with questions after I tried again. BR Goran

Hi Goran,
Without any exact details, like error messages and commands that you tried
we cannot give you much help sadly.
Please provide all details possible in text format, and I’m sure someone
will help.

HI,
My name is Goran, I have femto cell would like test osmo iuh. Installed
libosmocore on debian server, but got lot of problems with osmo IuH
compiling. Curenlty I am stucked with osmo-sccp library.
Also tried Vagrant IuH image, but there is issue with permisions,
Is there a way to get some help for solving this issues,
Thanks

From "my" branches, I can see the following:

* laforge/gprs-suspend -> osmo-bsc

For TMSI allocation, my "cryptographic gut feeling"[tm] is that
something like rand() or any other pseudo-random generator of
significantly large period is sufficient *if* it is seeded by a
non-predictable value. So something like seeding with getrandom() result
should be fine?
Might also make sense to periodically re-seed from /dev/urandom /
getrandom(), like every 100 TMSIs, or based on a timeout might be
easier to implement.
I would try to avoid any predictability here. Having a fixed time
interval would be known to an attackers. So if he was somehow able to
reduce/exhaust the entropy at the known time for re-seeding, it would be
bad.
Similar for "every 100 TMSIs", which is something under control of any
attacker as he can control the number of location updates via the public
radio interface [to some extent] and thus control the time at whcih
re-seeding is done.
Maybe I'm going overboard here, but I think if you want to re-seed, you
want to ideally do it at a non-predictable and non-controllable point in
time. Like a random time interval ;)
For long-term stable key (Ki/Op) generation for provisioning SIM
cards + populating a HLR, I would certainly opt for using stronger
randomness sources. However, I don't think we actually implement
that anywhere, do we?
what does openssh use for public/private keypair generation?
I'm not sure you can compare the requirements for generation of RSA
public/private keys with those for generation of symmetric keys. You can
find different recommendations in the literature. But I guess that's
mainly due to the fact that people usually assume you have long-term stable
public/private keys and short-lived symmetric session keys. In our case,
it's long-lived symmetric keys.
But as indicated, I think our focus is to find a proper solution for
generation of TMSIs and for random numbers used in authentication
challenges. K/OPc pair generation is not supported in current Osmocom
tools anyway, as we presume the SIM cards already have sufficiently random
key material and those keys are entered into the HLR.

Harald

Is there any way to retrieve the value of OP from OPc and Ki?
No, that defeats the entire purpose of having card-individual OPc values.
If you could just revert that operation, there would be no [security]
advantage of card-individual OPc values over a global OP value, and hence
that entire option could be dropped from the specifications altogether.

Harald

Hi Neels,

correct.
I notice though that we do still have open doors for a lot of nonsense
being sent to it without proper validation or error messages.
GET 42 existing-variable.trailing.names.ignored more nonsense
following being ignored
in effect is identical to:
GET 42 existing-variable
So we should probably enforce that there is no ignored nonsense...
I agree.
Should we also enforce a numeric command ID?
I'm not following here. Where would that numeric command ID comning from?
GET currently-any-id-is-possible-even-\t-\n-is-accepted my-command
this is also not intended, I'm quite sure.
Going back to the OsmoHLR CTRL commands -- they are implemented in a
way that doesn't match the CTRL interface ways. Let's collapse them.
SET enable-ps <IMSI>
SET disable-ps <IMSI>
SET status-ps <IMSI>
indeed, this is not proper.
SET subscriber.by-imsi.123456789098765.ps-enabled 1
SET subscriber.by-imsi.123456789098765.ps-enabled 0
GET subscriber.by-imsi.123456789098765.ps-enabled
makes a lot of sense to me.
We can also expand this later to things like
GET subscriber.by-imsi.123456789098765.status
SET subscriber.by-imsi.123456789098765.msisdn 2345
GET subscriber.by-msisdn.2342.status
SET subscriber.by-msisdn.2342.ps-enabled 0
GET subscriber.by-imei.987654321234565.imsi
looks good!
We could leave the enable-ps, disable-ps, status-ps commands in place
in case anyone is using it yet. I assume no-one is though.
I don't think we need to keep compatibility at this point.
