[PATCH 2/6] osmo-nitb: add -M to pass specific MNCC socket path

[PATCH 1/6] enable telnet VTY bind address config for various programs
by Neels Hofmeyr 24 Feb '16

24 Feb '16

Following the 'line vty'/'bind A.B.C.D' command added in libosmocore, use the configured address to set the telnet bind for the VTY line. It is now possible to publish the VTY on a specific local interface (including 0.0.0.0 aka "any"). Implement in all of: osmo-gbproxy osmo-gtphub osmo-sgsn osmo-bsc osmo-bsc_nat osmo-bsc_mgcp osmo-nitb In some of these main programs, move the telnet initialization below the configuration parsing. Historically, this was not a good idea for programs using bsc_init.c (aka bsc_bootstrap_network()), since they expected a gsm_network struct pointer in ((struct telnet_connection*)vty->priv)->priv, so that telnet had to be either initialized or replaced by a dummy struct. In the meantime, the gsm_network struct is not actually looked up in a priv pointer but in the static bsc_vty.c scope (bsc_gsmnet), so this limitation is mere legacy (even though said legacy is still there in an "#if 0" chunk). In the other binaries I have briefly looked at the init sequence dependencies and found no reason to initialize telnet above the config file parsing. In any case, I have tested every single one of abovementioned binaries to verify that they still parse the example config successfully and launch, allowing VTY connections on the configured address(es). I hope this suffices. In all of the above, log VTY address and port. LOGL_INFO is disabled by default in some of the logging scopes, and since it is a single log message right at program launch, I decided for the slightly more aggressive LOGL_NOTICE. --- openbsc/src/gprs/gb_proxy_main.c | 12 ++++++++---- openbsc/src/gprs/gtphub_main.c | 11 ++++++++--- openbsc/src/gprs/sgsn_main.c | 11 ++++++++--- openbsc/src/libbsc/bsc_init.c | 6 +++++- openbsc/src/osmo-bsc_mgcp/mgcp_main.c | 6 +++++- openbsc/src/osmo-bsc_nat/bsc_nat.c | 7 ++++++- 6 files changed, 40 insertions(+), 13 deletions(-) diff --git a/openbsc/src/gprs/gb_proxy_main.c b/openbsc/src/gprs/gb_proxy_main.c index f82fb5b..0c3cfbe 100644 --- a/openbsc/src/gprs/gb_proxy_main.c +++ b/openbsc/src/gprs/gb_proxy_main.c @@ -252,10 +252,6 @@ int main(int argc, char **argv) rate_ctr_init(tall_bsc_ctx);

[PATCH] ipa driver: make bind address vty configurable

Add VTY function to set the ipa bind address: e1_input ipa bind A.B.C.D Add a priv pointer to struct e1inp_driver in order to communicate the bind address parameter to ipaccess_line_update().

[PATCH] configure Abis/IP bind address
by Neels Hofmeyr 23 Feb '16

23 Feb '16

This patch allows Abis/IP bind address config for osmo-nitb as well as the osmo-bscs, without touching openbsc.git. This is the libosmo-abis part of making osmo-nitb's IP addresses configurable instead of always listening on 'any'. This will allow running more than one on the same box. Ctrl interface and vty are to follow, though not in this repo. I did sink a bit of time until the penny dropped that all I need to do is add a VTY command in libosmo-abis, but I did find out eventually.

rebase sysmocom-iu? branch 'jerlbeck/fixes/sgsn' merged to master
by Neels Hofmeyr 22 Feb '16

22 Feb '16

Hi Daniel, the 'jerlbeck/fixes/sgsn' branch has been merged to master. sysmocom-iu has some merge conflicts in the SGSN, so I assume it's better if you do the rebase of sysmocom-iu onto master. Agree? It would also be nice if we did the merge together ... maybe ping me when you do the rebase and I'll see if I join you. I would like to stay as close to master as possible to avoid conflict build up. If you could do the rebase sooner rather than later, that would be great. Thanks! (I could have told you in person but it's good to let the list know, too) ~Neels -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Holger Freyther, Harald Welte

osmo-nitb configurable
by Neels Hofmeyr 22 Feb '16

22 Feb '16

Hi Harald, Holger has just refreshed my memory on a conversation we've had on running multiple NITB instances on the same box: Linux Network Namespaces vs. making NITB configurable. Kindly remind me of the immediate plans, should we make osmo-nitb configurable to bind on only specific IP addresses, like, now? IIUC that would be a VTY item for osmo-nitb and a parameter into libosmo-abis. Concerning the VTY, the port could be configurable, or the IP address, thinking of 127.0.0.42. I guess relying on `ip netns` would be quicker for now, and I'd have slightly more time for IuCS. Is there anyone else out there that would love to configure osmo-nitb to bind on specific IP addresses only?
