sorry for the noise at osmo-msc patches
by Neels Hofmeyr 21 Jul '17

21 Jul '17

btw, I apologize for the noise around the osmo-msc patch review, it's a challenge to keep all the eggs in the basket. For once I added python tests as well as the various --enable- flags to 'make distcheck', then tried to get the patches to pass the build check, and only now am really taking care of the all the remaining code review. Every time I think it's settled, something else pops up. Hope to be done with the current batch today. ~N

by Harald Welte 21 Jul '17

21 Jul '17

Review at https://gerrit.osmocom.org/3323 Use TCP port numbers for VTY that don't overlap with other Osmocom Software osmo-pcap historically was using port numbers that ware already used by OsmoPCU and OsmoBTS. This leads to problems when wanting to run related software together on one system. Let's break the historical assumptions and start with non-overlapping port numbers that are allocated/assigned from https://osmocom.org/projects/cellular-infrastructure/wiki/Port_Numbers Change-Id: I638ac0534517931d0987ce9f72f5db4f5b6c16b7 --- M include/osmo-pcap/common.h M osmoappdesc.py M src/osmo_client_main.c M src/osmo_server_main.c 4 files changed, 13 insertions(+), 4 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-pcap refs/changes/23/3323/1 diff --git a/include/osmo-pcap/common.h b/include/osmo-pcap/common.h index 13c76e1..27fd514 100644 --- a/include/osmo-pcap/common.h +++ b/include/osmo-pcap/common.h @@ -28,6 +28,15 @@ #include <osmocom/vty/vty.h> #include <osmocom/vty/buffer.h> #include <osmocom/vty/command.h> +#include <osmocom/vty/ports.h> + +/* support old versions of libosmocore */ +#ifndef OSMO_VTY_PORT_PCAP_CLIENT +#define OSMO_VTY_PORT_PCAP_CLIENT 4237 +#endif +#ifndef OSMO_VTY_PORT_PCAP_SERVER +#define OSMO_VTY_PORT_PCAP_SERVER 4238 +#endif enum { DPCAP, diff --git a/osmoappdesc.py b/osmoappdesc.py index 39928eb..6f66702 100644 --- a/osmoappdesc.py +++ b/osmoappdesc.py @@ -20,8 +20,8 @@ } apps = [ - (4241, "src/osmo_pcap_server", "OsmoPCAPServer", "osmo-pcap-server"), - (4240, "src/osmo_pcap_client", "OsmoPCAPClient", "osmo-pcap-client"), + (4238, "src/osmo_pcap_server", "OsmoPCAPServer", "osmo-pcap-server"), + (4237, "src/osmo_pcap_client", "OsmoPCAPClient", "osmo-pcap-client"), ] vty_command = ["src/osmo_pcap_server", "-c", "contrib/osmo-pcap-server.cfg"] diff --git a/src/osmo_client_main.c b/src/osmo_client_main.c index 89d7e04..46a49b5 100644 --- a/src/osmo_client_main.c +++ b/src/osmo_client_main.c @@ -206,7 +206,7 @@ osmo_tls_init(); - rc = telnet_init(tall_bsc_ctx, NULL, 4240); + rc = telnet_init(tall_bsc_ctx, NULL, OSMO_VTY_PORT_PCAP_CLIENT); if (rc < 0) { LOGP(DCLIENT, LOGL_ERROR, "Failed to bind telnet interface\n"); exit(1); diff --git a/src/osmo_server_main.c b/src/osmo_server_main.c index 37a9632..95f3ce1 100644 --- a/src/osmo_server_main.c +++ b/src/osmo_server_main.c @@ -219,7 +219,7 @@ osmo_tls_init(); - rc = telnet_init(tall_bsc_ctx, NULL, 4241); + rc = telnet_init(tall_bsc_ctx, NULL, OSMO_VTY_PORT_PCAP_SERVER); if (rc < 0) { LOGP(DCLIENT, LOGL_ERROR, "Failed to bind telnet interface\n"); exit(1); -- To view, visit https://gerrit.osmocom.org/3323 To unsubscribe, visit https://gerrit.osmocom.org/settings Gerrit-MessageType: newchange Gerrit-Change-Id: I638ac0534517931d0987ce9f72f5db4f5b6c16b7 Gerrit-PatchSet: 1 Gerrit-Project: osmo-pcap Gerrit-Branch: master Gerrit-Owner: Harald Welte <laforge(a)gnumonks.org>

by Harald Welte 21 Jul '17

21 Jul '17

Review at https://gerrit.osmocom.org/3322 Rename osmo_pcap_{client_server} executables to osmo-pcap-{client,server} This naming is more in line with what all the other osmocom programs are doing (e.g. osmo-pcu, osmo-bts-sysmo, osmo-bsc, ...). We don't generally use osmo_ anywhere else, so I suggest to change it for more uniformity.

Documentation on how to use virtual Um between BTS + MS
by Harald Welte 20 Jul '17

20 Jul '17

Hi! Next to the announcement (http://osmocom.org/news/75) I've put together some guide in the wiki as to how the Virtual Um interface can be used with the osmo-bts-virtual, virtphy and mobile programs running all on your local PC: https://osmocom.org/projects/cellular-infrastructure/wiki/Virtual_Um Feel free to try it out and/or improve the wiki page and/or let me know if something is not sufficintly clear. I intentionally don't want to repeat general information about configuring OsmoNITB or using OsmocomBB. The above-mentioned page should only document those aspects that are different from the classic setup with real hardware. I'm now investigating some more of the bugs I'm starting to find with using the VirtualUm interface from my related TTCN-3 testsuite, at this time particularly https://osmocom.org/issues/2380 Will document that testsuite once it can actually run as expected.

GSMTAP based Virtual PHY merged in OsmocomBB and OsmoBTS
by Harald Welte 19 Jul '17

19 Jul '17

Hi all! Some of you will have alrady noticed, over the last few days I reviewed, cleaned up, submitted and merged the virtual Um interface support on both the phone side (OsmocomBB) as well as on the BTS side (OsmoBTS). Thanks to Sebastian Stumpf for working out most of the related code, after my initial attempt on this got stalled more than 1.5 years ago. This means that you can now run a complete circuit-switched GSM network without posession of any real hardware or use of any radio waves. While that takes away almost all the fun for some of us (I would typically agree), it opens up possibilities, particularly in terms of testing. If anyone wants to play with it, it's actually very easy: * build osmo-bts and the rest of the network-side code (I don't think osmo-bts-virtual is part of the nightly Osmocom packages yet, sorry) * run osmo-bts-virtual with a config file (example included in osmo-bts.git) * make sure you have matching unit_id, band, ... between BTS and BSC/NITB, just like with real hardware OsmoBTS will start to send downlink BCCH / CCCH frames to a multicast IPv4 address (default: 239.193.23.1) to the usual GSMTAP port 4729. If you don't have any specific multicast routing set up, this will be visible with TTL=1 on the network device of your default route. You should see the GSMTAP frames in wireshark. On the OsmocomBB side, simply start the virt_phy binary. It replaces your calypso based phoen and its firmware and offers the L1CTL socket to the "layer23" programs like "mobile". Once virt_phy is running, you can start "mobile" just like with real hardware. The phone will scan the multicast frames for BCCH messages, build up a list of currently received BTSs and then perform normal cell selection followed by location update. Everything from this point on is just normal. You cannot make voice calls, but any signaling related transactions (LU, SMS, USSD, even call signalling) should work. Voice is missing as there is no format specified on how to transmit FR/EFR/HR/AMR frames over GSMTAP yet. If somebody plays with this, I would really appreciate if they could update the Osmocom wiki with a guide/howto on how to use such a setup. My personal plans are to use this for verification/testing of those bits that are difficult in a true end-to-end setup like osmo-gsm-tester. That includes: * simulation of massive amount of phones, more than one can easily set up in a lab and connect to USB + RF cabling. * verification of SYSTEM INFORMATION messages, particularly in response to different config files, ensuring that all related bits are set correctly at all times, even after making dynamic updates * verification of the PAGING code, i.e. that paging load is correctly reported, paging messages are structured correctly, ... * exhausting all channels using simulated phones, verification of IMM.ASS.REJECT being sent ins such cases * verification of TA loop * verification of uplink power control loop * verification of radio link timeout * testing of emergency calls, which is very critical with real phones as there's always some possible leakage into real networks * verification of correct CBCH messages * verification of LAPDm contention resolution (two phones selecting same RACH value and going both on same dedicated channel) * verification of measurement reporting (Um vs. RSL) * verification of downlink RF power ramping This will of course take some time, but I'm already making good progress implementing some SYSTEM INFORMATION test code. In case somebody wants to join in on any of the above topics (or has even more ideas on what kind of tests he would want to implement), feel free to follow up so we can coordinate.

osmo-nitb enable SMS delivery reports
by Anonim Stefan 19 Jul '17

19 Jul '17

Hi, I'm using osmo-nitb in a testing environment and I've soon received a request to enable SMS delivery reports. After looking on the user manual, I couldn't find anything related to this. I've also enabled debug logging and tried to grep for something like that when sending a SMS between two handsets that have SMS delivery reports enabled, without finding out anything. (SMS delivery reports tested and worked on a public telephony system, for those two handsets) Is there such an option available in osmo-nitb to enable delivery reports? --- Thank you, Stefan
