Unable to configure a BTS
by Luca Bertoncello 26 Jul '10

26 Jul '10

Hi, again! So, as I said in my last E-Mail, I got a new BTS (DSC1800). Now I have to configure it, so I started ipaccess-find to get his IP and then ipaccess-config to configure it. I get this error: lucabert@Luca:/tmp$ ipaccess-config -u 151/0/0 -o 192.168.1.18 192.168.1.108 ipaccess-config (C) 2009-2010 by Harald Welte and others This is FREE SOFTWARE with ABSOLUTELY NO WARRANTY Trying to connect to ip.access BTS ... Lost some E1 TEI link Lost some E1 TEI link Segmentation fault Can someone say me what is the problem?

Detect phone calls
by Luca Bertoncello 26 Jul '10

26 Jul '10

Hi, list! Of course OpenBSC knows which phone-calls there are right now. I'd like to get this list. How can I do this? Thanks a lot! -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 23 Kesselsdorfer Str. 216, 01169 Dresden Fax: 0351/41381 - 12 HRB 18926 / Ust.ID DE211326547 Mail: netzing.ag(a)netzing.de _______________________________________________________________________

Re: PATCH/RFC use recvfrom with MSG_TRUNC as flag

Hello Holger, On Fri, 23 Jul 2010 21:38:36 +0800, "Holger Hans Peter Freyther" <holger(a)freyther.de> wrote: > > PS: How big is your diff to make it compile on Windows? I have not ported the TUN calls yet. My last try for OpenBSC plus GPRS was in a Linux VM, however I had problems there with the TUN interface. I could see outgoing packets with proper NAT translation (the DNS queries from the phone) and I could also see the DNS replies "outside" the VM but they never got through to the TUN interface. Maybe its a problem related to the VM, but after this experience I decided to wait playing with the TUN interface on Cygwin because it probably makes sense to have a running reference system first. BTW, anyone having OpenBSC plus GPRS running on MacOS X ? Thats the closest to Unix I have here besides a VM. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

[PATCH] Subscriber data in measurement report
by Luca Bertoncello 24 Jul '10

24 Jul '10

I find the measurement report of OpenBSC very difficult to read, because it is not possible to distinguish the various phones. Of course, it is possible to filter the log (logging filter imsi ...), but sometimes, as in my case, it is necessary to get the measurement reports of many phones at the same time. In this case, it is not possible to know which phone generate which report. I create a patch to solve this problem. With this patch, the measurement reports contain the lchan in which the call (or SMS) runs (just as information), the IMSI and the extension of the phone. If you are interested, here is it!

Thanks for asking. According to what I found so far, Cygwin should support MSG_TRUNC. However considering the fact that there is much more to do to get OpenBSC and GPRS running under Cygwin (porting the calls to access the TUN interface in OpenGGSN), one more obstacle should not really care ;-) (I guess I am the only one who uses OpenBSC on Cygwin).

PATCH/RFC use recvfrom with MSG_TRUNC as flag

Hi Harald, Dieter, what do you think of using MSG_TRUNC and checking if we have truncated our packets in a recv call? Dieter do you know if cygwin will silently ignore the MSG_TRUNC flag or if you will have a problem on Window? diff --git a/openbsc/src/gprs/gprs_ns.c b/openbsc/src/gprs/gprs_ns.c index 3db1d67..ab2d937 100644 --- a/openbsc/src/gprs/gprs_ns.c +++ b/openbsc/src/gprs/gprs_ns.c @@ -867,7 +867,7 @@ static struct msgb *read_nsip_msg(struct bsc_fd *bfd, int *error, return NULL; } - ret = recvfrom(bfd->fd, msg->data, NS_ALLOC_SIZE - NS_ALLOC_HEADROOM, 0, + ret = recvfrom(bfd->fd, msg->data, NS_ALLOC_SIZE - NS_ALLOC_HEADROOM, MSG_TRUNC, (struct sockaddr *)saddr, &saddr_len); if (ret < 0) { LOGP(DNS, LOGL_ERROR, "recv error %s during NSIP recv\n", @@ -879,6 +879,11 @@ static struct msgb *read_nsip_msg(struct bsc_fd *bfd, int *error, msgb_free(msg); *error = ret; return NULL; + } else if (ret > NS_ALLOC_SIZE - NS_ALLOC_HEADROOM) { + LOGP(DNS, LOGL_ERROR, "truncated msg. real size is: %d\n", ret); + msgb_free(msg); + *error = -ENOSPC; + return NULL; } msg->l2h = msg->data;

Problem to compile the last version of OpenBSC
by Luca Bertoncello 23 Jul '10

23 Jul '10

Hi, list! A very strange problem... Today I got a new BTS (DSC1800) and I tried to configure it. Unfortunately it does not respond correctly (I'll send a separate E-Mail about this problem), so I decided to try with the last version of OpenBSC (maybe a bug in ipaccess-config?). Unfortunately I can't compile it. I get these errors: gcc -Wall -I/usr/local/include/ -I/usr/local/include/ -g -O2 -L/usr/local/lib -losmocore -o bsc_hack bsc_hack.o bsc_init.o bsc_vty.o vty_interface_layer3.o libmsc.a libbsc.a

libosmocore now abort()s on msgb overflow/underflow
by Harald Welte 23 Jul '10

23 Jul '10

Hi! I've just committed a patch that will cause libosmocore to abort in case we try to msgb_put() beyond the end fo the buffer or msgb_push() ahead of the start. I hope we can uncover any hidden buffer under/overflows this way, if they exist.

Switch with PowerOverEthernet for a BaseStation
by Luca Bertoncello 21 Jul '10

21 Jul '10

Hi, list! We have actually 4 BaseStation (but in the future we will buy at least other 2). Now want my Boss to buy a PoE-Switch at which we connect all BaseStation. This Switch has to supply power, too. Now, I'm not sure (I don't know PoE in detail) if I can use every PoE-Switch. I searched in Internet and I found a Netgear FS108P. It's cheap and it will be enough for us. Can I use it with our BaseStation or have I to use the power supplier of the BaseStations, too? Thanks a lot for your answers! -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 0 Kesselsdorfer Str. 216, 01169 Dresden Fax: 0351/41381 - 12 HRB 18926 / Ust.ID DE211326547 Mail: netzing.ag(a)netzing.de _______________________________________________________________________
