Referring to a subnet

Hi I need to trust a subnet and was wondering if something like src_ip = x.x.x.x/27 where x.x.x.x is the network address of the subnet is valid in the config. I am using OpenSER 1.1.0 in this instance. -- Jon Farmer Tel: 07795 118140 Email: viperdudeuk(a)gmail.com Twitter: @viperdudeuk

Configuring TCP keep alive and connection lifetime

by Pascal Maugeri

"kamailio" <users(a)lists.kamailio.org>, Hi I am sorry to ask again about this topic but I don't understand yet how the TCP keep-alive are sent. With Kamailio 3.0.1 and the following configuration: tcp_keepalive=yes tcp_keepidle=10 tcp_connection_lifetime=3600 The TCP connection is kept alive and TCP Keep-Alive packets are sent when the TCP connection is idle. But I don't understand why the time between KA is not linear: first KA is sent 10 seconds after last last TCP message. This is logical and connected with the tcp_keepidle=10 configuration. then 2nd KA is sent 75 seconds after first KA Then my client sends some traffic and 23 seconds after last message, a new KA is sent. Another time it was 54 seconds. etc. etc. Could you explain me where do come from these values of 75 seconds, 23, 54 ? Everything works well: my client behind NAT is kept connected but I'd like to understand why it does work :-) Thanks in advance, Pascal

[LCR] Why 'gw_name' column is an UNIQUE index in 'gw' table?

by Iñaki Baz Castillo

Why is it an UNIQUE key? It makes things complex when I want to create another gateway with same IP and port (but belonging to a different grp_id). I still want to name it with the same name (an internal domain for example). Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>

Wrong handling CANCEL message

by pars3c

Hi, i have a problem about the handling of the "cancel" message. The call flow is this: A -----------------> (Invite) Proxy (P) B (100 Tryng) <--------------------------- ----------------->(Invite) B (100 Tryng) <--------------------------- (183 Progress) <--------------------------- (183 Progress) <--------------------------- (200 OK) <--------------------------- (200 OK) <--------------------------- --------------------------------->(CANCEL) (200 canceling) <--------------------------- (200 OK) <--------------------------- (200 OK) <--------------------------- ----------------->(ACK) ----------------->(ACK) (BYE) <--------------------------- (BYE) <--------------------------- ----------------->(481 Call Leg/Transaction Does Not Exist) ----------------->(481 Call Leg/Transaction Does Not Exist) The B side answer with OK, after a while , a send a CANCEL. I don't know why Kamailio don't forward this message to the B side. B retry to send the OK message, then A send the ACK. At the end , B send BYE , but A don't have the transactin. In this situation, kamailio should deliver the "CANCEL" to the B side ? (even if, before B send the OK ) Or the proxy should not consider the CANCEL because B has answered with "OK" ? Where is the error on my configuration ? Thanks I have Kamailio 1.5.3 and my configuration is this: modparam("siptrace", "trace_on", 0) modparam("carrierroute", "config_source", "db") modparam("auth_db", "password_column", "ha1") modparam("auth_db", "use_domain", 1) modparam("usrloc", "db_mode", 2) #modparam("usrloc","nat_bflag", 8) modparam("permissions", "trusted_table", "trusted") modparam("permissions", "db_mode", 1) modparam("permissions", "peer_tag_avp", "$avp(i:707)") modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") modparam("avpops","avp_table","usr_preferences") modparam("avpops","attribute_column","attribute") modparam("avpops","value_column","value") modparam("uac","from_restore_mode","auto") modparam("tm", "fr_timer", 12) modparam("tm", "wt_timer", 32) modparam("rr", "append_fromtag", 1) #modparam("rr", "enable_full_lr", 1) modparam("userblacklist", "use_domain", 0) #modparam("dialog", "dlg_flag", 2) modparam("registrar|nathelper", "received_avp", "$avp(i:42)") #modparam("registrar", "min_expires", 17000) modparam("acc", "db_flag", 2) modparam("acc", "db_missed_flag", 3) modparam("acc", "db_table_acc", "acc") modparam("acc", "db_table_missed_calls", "missed_calls") modparam("acc", "detect_direction", 1) route{ # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops"); exit; }; if (msg:len > max_len) { sl_send_reply("513", "Message Overflow"); exit; }; # ----------------------------------------------------------------- # Preprocessing # ----------------------------------------------------------------- if (!method=="REGISTER") record_route(); # ----------------------------------------------------------------- # NAT Detection # ----------------------------------------------------------------- force_rport(); if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); } setflag(7); } # ----------------------------------------------------------------- # # ----------------------------------------------------------------- sip_trace(); ##Loose_route packets if (has_totag()) { if (loose_route()) { if(method=="BYE") { #Account BYE transactions setflag(2); }; route(2); } else { if ( is_method("ACK") ) { if ( t_check_trans() ) { # non loose-route, but stateful ACK; # must be an ACK after a 487 or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard.\n"); exit; } } sl_send_reply("404","Not here"); } exit; } # ----------------------------------------------------------------- # CANCEL processing # ----------------------------------------------------------------- if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; }; t_check_trans(); # ----------------------------------------------------------------- # # ----------------------------------------------------------------- if (method =="OPTIONS" || method=="SUBSCRIBE") {exit;}; if (method =="REGISTER") {route(3);}; route(1); } route[2] { t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; exit; } .. failure_route[2] { if (t_was_cancelled()) { # xlog("INFO:cancelled transaction--\n"); exit; } revert_uri(); .. t_on_failure("2"); append_branch(); if (!t_relay()) { exit; }; }

auth_db authorize realm

by Alex Balashov

There is a peculiar and confusing aspect to the documented significance of the "realm" argument to www_authorize(), and presumably proxy_authorize() as well. The documentation says that if this value is empty, the digest realm will be generated from the domain part of the To or From URI, whichever is applicable to the given situation (REGISTER vs. any other request). This is the way *_authorize() is invoked in most cases, and works fine. However, we recently ran into a situation where www_authorize() would always fail and claim that it could not find the user in 'subscriber' despite being provided correct username and domain, with the appropriate options -- return value -1. We were sending the public host IP as the domain of the To URI, using it as the realm, and setting it in the domain column of the 'subscriber' table. The problem was, the public IP of the host was not in /etc/hosts -- /etc/hosts consisted solely of: 127.0.0.1 localhost.localdomain localhost For some reason, it wasn't until I added the public IP into it that www_authorize() started working properly: 127.0.0.1 localhost.localdomain xxx.xxx.xxx.xxx public_host.domain.tld public_host I don't see anything different in the anatomy of the 401 Unauthorized challenges; the realm is still xxx.xxx.xxx.xxx in both cases. It just seems that unless Kamailio detects a DNS reverse alias for the domain, it won't properly authenticate requests. This aspect of the behaviour is not documented, and I am also confused as to why it happens this way. Any clarification would be appreciated. -- Alex Balashov - Principal Evariste Systems LLC 1170 Peachtree Street 12th Floor, Suite 1200 Atlanta, GA 30309 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/

segfault kamailio 3.01 avp_copy flag g

by Jon Bonilla

Hi all I have experienced segfaults when using avp_copy in Kamailio 3.01. This happens when using the "g" flag and the avp is not null (no problem if it has no content) avp_copy("$avp(s:block_out_list)", "$avp(s:caller_block_out_list)/gd"); Removing the "g" flags works ok (but does not copy all the content of course): avp_copy("$avp(s:block_out_list)", "$avp(s:caller_block_out_list)/d"); Directly copying the avp works fine: $avp(s:caller_block_out_list) = $avp(s:block_out_list); Logs: kernel: [1503237.523015] kamailio[8156]: segfault at 1008eb91c ip 505344 sp 7fffffffad10 error 4 in kamailio[400000+1c9000] WARNING: <core> [usr_avp.c:483]:AVP specified with index, but not used for search ALERT: <core> [main.c:722]: child process 8156 exited by a signal 11 ALERT: <core> [main.c:725]: core was not generated INFO: <core> [main.c:737]: INFO: terminating due to SIGCHLD INFO: <core> [main.c:788]: INFO: signal 15 received
