[PATCH 1/2] gbproxy: Add test for NSEI and NSVCI changes
by Jacob Erlbeck 24 Oct '13

24 Oct '13

This checks the behavior of the gbproxy when the BSS peer changes the NSEI and the NSVCI. It also tests BVC_RESET and other UNITDATA messages after these changes between BSS and SGSN and vice versa (via the gbproxy).

[PATCH 1/3] gb/vty: Perform NS-VC operations based on NS-VCI

This adds a 'nsvc nsvci <0-65535> (block|unblock|reset)' vty command. It selects the NS-VC based on the nsvci instead of using the first with a matching NSEI, like it is done when the 'nsei' keyword is used instead.

Re: Hard reset NanoBTS after forgetting static IP
by Daniel Fligg 24 Oct '13

24 Oct '13

I have come across a nanoBTS 165AU but since is used and not tested from the previous owner, I guess it has set a static IP. After turned on is booting (RED light) and then remains (ORANGE not flashing) even if the eth is connected to the router. Based on observation, constant blinking orange seems to indicate the layer 2 link isn't up (eg it's powered but Ethernet isn't connected). Solid orange is good. Once it's fully booted it seems to be solid orange with a very quick flash off once a second seems to indicate it's trying to find the BSC > At the moment I am trying with ipaccess-find and BtsInstaller to find in on my LAN . > Unfortunately it is not answering and is not even getting an IP from the router by the DHCP daemon. > > ipaccess-find / btsinstaller only ever seem to find my BSCs when the machine they're running on is on the same subnet. The easiest way to track down a rogue bts is to connect it directly to a spare network port in the pc and then run wireshark on it. On boot my BTS sends a number of dhcp inform requests broadcasting it's IP and then starts blasting packets at the BSC address. Hope this helps,

[PATCH] gb: Fix gprs_nsvc_delete() to free ctr group

OpenBSC with USRP2 : rsl.c error
by Joe Ge 22 Oct '13

22 Oct '13

Hi all, I know this problem has been dealt previously in a minor variation but please help me out here. I'm trying to configure OpenBSC using the USRP N210 device and followed the same network from scratch installation. I got up to the part where sysmobts gives the error and corrected it by editing the makefile. But unlike others my 'make' command is giving me an error in the rsl.c file. make[2]: Entering directory `/home/prabu/OpenBSC-OpenBTS/osmo-bts/src/common' CC rsl.o rsl.c:140:2: warning: #warning merge lchan_lookup with OpenBSC [-Wcpp] rsl.c: In function ‘rsl_rx_chan_activ’: rsl.c:779:53: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c:783:15: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c: In function ‘rsl_rx_mode_modif’: rsl.c:1028:53: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ rsl.c:1032:15: error: ‘struct gsm_lchan’ has no member named ‘mr_bts_lv’ make[2]: *** [rsl.o] Error 1 make[2]: Leaving directory `/home/prabu/OpenBSC-OpenBTS/osmo-bts/src/common' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/prabu/OpenBSC-OpenBTS/osmo-bts/src' make: *** [all-recursive] Error 1 Can someone please help me out in what this error deals with.
