Kamailio as a LB with Asterisk and consul
by Sylvain Boily 06 Oct '15

06 Oct '15

Hello, I did a new small project with Asterisk to register it on consul (http://consul.io) to use a discovery service tools. The project is here : https://github.com/sboily/asterisk-consul-module This last day, i'm working to use kamailio as a loadbalancer for Asterisk and autoscale it. You can find example on my docker-compose.yml, contribs directory and README. It's not perfect, because i'm clearly not a kamailio expert, but it works. So, i'm looking about feeling to this dev, and i would expect some help from kamailio community to configure kamailio as a LB better ;) I will be at astricon, so if people want to share with me about this project, contact me. Have a good day Sylvain

creating debian package from source
by Thibault Gueslin 06 Oct '15

06 Oct '15

I have difficulties to install the debian package of kamailio I have build from source Creation works fine. (make cfg, configuration of proper debian in pkg/debian/deb , make deb) But kamailio tries to find module here : /usr/lib/x86_64-linux-gnu/kamailio/modules/ and modules are installed in /usr/lib64/ Of course, it works fine by specifying -L with actual path. I have tried also to download the source of debian package with same result. I have missed some steps. Thibault

Re: [SR-Users] diameter auth with round trip
by JB 06 Oct '15

06 Oct '15

Thanks for the suggestion about auth_diameter, do you think there would be an interest in the community if we were to do this modification on ims_auth or auth_diameter ? could it be integrated to trunk ? We do not want to publish our own fork of ims_auth or auth_diameter with that small change and maintain the code repository if it can be avoided, so it would be nice if we can put it in the trunk and forget about it. Plus it is more open source oriented to publish to main branch i feel :) JB 2015-10-03 23:53 GMT+02:00 JB <jbf.nospam(a)gmail.com>: > Hello all, we are working on a SIP solution using Kamailio. > > We want to secure our base of user credentials even in case of attack on > the SIP server, and for that reason we plan to use diameter authentication > as described in RFC http://www.rfc-base.org/txt/rfc-4740.txt > > Paragraph 6.2 describes a mode where the HSS answer with code > > DIAMETER_MULTI_ROUND_AUTH ,and then validate user credential after a second round trip. > > > This does NOT corresponds to what is done on Kamailio module ims_auth, where credentials (actually a hash of the credentials, but its enough to authenticate ) > > ) are pushed to kamailio, which does the computation of the expected answer (which corresponds to par 6.3 of the RFC 4740) > > Is there any kamailio module that would allow to use the method with DIAMETER_MULTI_ROUND_AUTH ? > > Thank you > > JB > >

diameter auth with round trip
by JB 06 Oct '15

06 Oct '15

Hello all, we are working on a SIP solution using Kamailio. We want to secure our base of user credentials even in case of attack on the SIP server, and for that reason we plan to use diameter authentication as described in RFC http://www.rfc-base.org/txt/rfc-4740.txt Paragraph 6.2 describes a mode where the HSS answer with code DIAMETER_MULTI_ROUND_AUTH ,and then validate user credential after a second round trip. This does NOT corresponds to what is done on Kamailio module ims_auth, where credentials (actually a hash of the credentials, but its enough to authenticate ) ) are pushed to kamailio, which does the computation of the expected answer (which corresponds to par 6.3 of the RFC 4740) Is there any kamailio module that would allow to use the method with DIAMETER_MULTI_ROUND_AUTH ? Thank you JB

defaults missing from tcp ops module readme
by Juha Heinanen 05 Oct '15

05 Oct '15

after seeing some commits on tcpops module, i decided to check its readme and noticed that nothing is mentioned about the default values of parameters. it might be useful to tell that, e.g., if tcp_keepalive_enable is not set, then tcp_keepalive core parameter value tells what the status is. -- juha

problem with dispatcher load balancing
by Ding Ma 05 Oct '15

05 Oct '15

I'm trying to set up kamailio dispatcher to distribute calls to 2 asterisk servers. So far, the failover case seems ok, but I cannot get the dispatcher to distribute load. All calls are going to the last destination entry in the dispatcher table even if I have set the maxload attributes. I'm using algorithm 10 for load distribution. The number of calls sent to one asterisk is well above the maxload. Hope someone more experienced in dispatcher can review my config and give me some recommendations. Thanks in advance. Here is the content of dispatcher table in postgresql db. select * from dispatcher; id | setid | destination | flags | priority | attrs | description ----+-------+--------------------+-------+----------+---------------------------+------------- 1 | 1 | sip:10.0.1.31:5061 | 0 | 0 | duid=asterisk1;maxload=25 | Asterisk1 2 | 1 | sip:10.0.1.33:5061 | 0 | 0 | duid=asterisk2;maxload=25 | Asterisk2 (2 rows) Here are the dispatcher sections in kamailio.cfg. # ----- dispatcher params ----- #!ifdef WITH_DISPATCHER modparam("dispatcher", "db_url", DBASTURL) modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "force_dst", 1). # If flag 2 is set, then failover support is enabled. modparam("dispatcher", "flags", 3) # the last address in destination set is used as a final option to send the request to modparam("dispatcher", "use_default", 1) # load balancing fail over modparam("dispatcher", "dst_avp", "$avp(dsdst)") modparam("dispatcher", "grp_avp", "$avp(dsgrp)") modparam("dispatcher", "cnt_avp", "$avp(dscnt)") modparam("dispatcher", "dstid_avp", "$avp(dsdstid)") modparam("dispatcher", "attrs_avp", "$avp(dsattrs)") # PVs for hashing modparam("dispatcher", "hash_pvar", "$fU@$ci") # PVs to store results when calling ds_is_from_list modparam("dispatcher", "setid_pvname", "$var(setid)") modparam("dispatcher", "attrs_pvname", "$var(attrs)") # method to probe the gateways modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:dispatcher@localhost") modparam("dispatcher", "ds_ping_interval", 30) modparam("dispatcher", "ds_probing_threshhold", 10) modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=403;code=404;code=484;code=488;class=3") modparam("dispatcher", "ds_probing_mode", 1) # size of hash table storing data for call load dispatching, power of two modparam("dispatcher", "ds_hash_size", 10) # expiration time in seconds to remove the load on a destination if no BYE was received modparam("dispatcher", "ds_hash_expire", 3600) # expiration time in seconds to remove the load on a destination if no 200 OK for INVITE was received # and state updated with ds_load_update modparam("dispatcher", "ds_hash_initexpire", 60) modparam("dispatcher", "ds_hash_check_interval", 30) #!endif route[WITHINDLG] { if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing #!ifdef WITH_DISPATCHER if(is_method("BYE|CANCEL") && ds_is_from_list("1", "3")) ds_load_update(); #!endif ...... } } route[FROMASTERISK] { #!ifdef WITH_DISPATCHER if(ds_is_from_list("1", "3")) { xlog("L_DBG","$rm from $fU@$si:$sp: Call from Asterisk cluster\n"); return 1; } return -1; #!else if ($si==$sel(cfg_get.asterisk.bindip)) { return 1; } return -1; #!endif } onreply_route[MANAGE_REPLY] { xdbg("incoming reply\n"); #!ifdef WITH_DISPATCHER if(is_method("INVITE") && ds_is_from_list("1", "3")) { if(status=~"2[0-9][0-9]") { ds_load_update(); } else if(status=~"[3-7][0-9][0-9]") { ds_load_unset(); } } #!endif if(status=~"[12][0-9][0-9]") route(NATMANAGE); } #!ifdef WITH_DISPATCHER failure_route[RTF_DISPATCH] { if (t_is_canceled()) { exit; } # next DST - only for 500 or local timeout if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) { # mark the destination Inactive and Probing ds_mark_dst("IP"); # select the new destination if(ds_next_dst()) { t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } else { # last available node failed to reply, no other destinations available send_reply("404", "No destination"); exit; } } } #!endif route[TOASTERISK] { #!ifdef WITH_DISPATCHER # ds_mark_dst("IP"); # Call load distribution if(!ds_select_dst("1", "10")) { sl_send_reply("500", "Service Unavailable"); xlog("L_INFO","$rm from $fU@$si:$sp: No destinations available for $rd\n"); exit; } xlog("L_DBG", "--- SCRIPT: going to <$ru> via <$du>\n"); t_on_failure("RTF_DISPATCH"); #!else $du = "sip:" + $sel(cfg_get.asterisk.bindip) + ":" + $sel(cfg_get.asterisk.bindport); #!endif route(RELAY); exit; } # Dispatcher detects a destination goes down event_route[dispatcher:dst-down] { xlog("L_ERR", "Destination down: $rm $ru ($du)\n"); } # Dispatcher detects a destination comes up event_route[dispatcher:dst-up] { xlog("L_ERR", "Destination up: $rm $ru\n"); }
