Hi, I have a sip registrar.(kamailio server installed in one server) I want to use the siremis 2.0 to collect management information from the sip registrar. Can you guide me how to make the connection between the sip registrar and the siremis so that the stats can be collected? Thanks

Re: [SR-Users] How does RLS work with kamailio.

by Gnaneshwar Gatla

Hello, I have partly fixed this, I was using an incorrect xml format and missing usage of pua module. It took a little more than debugging to find this out. Now I have run into this new issue. I have implemented a presence + rls + xcap server: When client subscribes for RLS, kamailio Notifies with resourcelist for the client. The pua within the server does backend subscribtions. These backend subscribtions are responded with 202 Accepted replies. When the resources in the contact list change their presence information the pua generates NOTIFIY with subscription state: pending. Rls module does not reply back. Kamailio does not return from the following command. if(is_method("NOTIFY")) { xlog("handle notify"); rls_handle_notify(); xlog("notify was handled"); exit; }; Thank you for looking into this. Regards Gnani From: Gnaneshwar Gatla Sent: Thursday, April 19, 2012 4:53 PM To: SIP Router - Kamailio (OpenSER) and SIP Express Router (SER) - Users Mailing List Cc: Cody Herzog Subject: How does RLS work with kamailio. Hello, I'm trying to implement RLS with integrated XCAP server. I have successfully run the Kamailio instance with the following snippet. Since I had no RLS clients available, I have tried to test this with SIPp. The attached pcap trace is the result. Test: 1. Send an XCAP signal over http to Kamailio. 2. Register and subscribe Kamailio. The test does store the xml received over http in the xcap table in the database. But rls module does not store the data neither in rls_presentity or rls_watcher. When I sent the Subscribe with sipp, the server throws error that subscription was not found in the database. I would like to know if I'm doing something wrong to implement this service. Is there any brief tutorial on how to implement this?

I have been able to successfully update xcap documents on Kamailio XCAP server. I have tried to use SIPp to get a NOTIFY for subscribing a rls-service list. Kamailio does get the xml from the xcap table and tries to parse it and crashes. I'm not sure if this is because the format of the XML, I derived the xml format from the RFC 4662 and 4826.

TLS performance testing

by Kristian Kielhofner

Hello everyone, I'm doing some TLS performance testing on Kamailio 3.2.1. Here's my setup: kamailio -V version: kamailio 3.2.1 (x86_64/linux) 31c991 flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS, USE_STUN, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 31c991 compiled on 19:38:03 Dec 20 2011 with gcc 4.4.6 uname -a Linux null.null.com 2.6.32-220.el6.x86_64 #1 SMP Tue Dec 6 19:48:22 GMT 2011 x86_64 x86_64 x86_64 GNU/Linux CentOS 6.2 on a Dell PowerEdge R610 with 24 Intel X5650 Cores at 2.67GHz and 12GB of RAM (I could use more). Kamailio is the default config with a few changes: - WITH_TLS defined - TLS is using self-generated CAs/certs (essentially openvpn easy-rsa) with 1024 bit key size - TLS is *not* configured to verify client OR server certs by default - I'm using TLS v1 (SSL 3.1) - TLS cipher suites are set to any (although my simulated UAs only offer AES 256+SHA) - Various changes to Kamailio children (up to 256 at times) and memory sizes (up to 2048mb and even 4096mb at times) - One DNS based alias added - Maximum TCP connections increased to 65000 - Kamailio is configured to only listen on tested IP (UDP, TCP, TLS sockets active) - Syslog has been configured to log local0 (Kamailio) asynchronously My test rig/call generator is an Ixia Xcellon-Ultra NP load module with IXLoad. My call scenario does the following: - Registers two simulated user agents (100000, 200000) to Kamailio with TLS - Places call from 100000 to 200000 via Kamailio with TLS - Increments both user agents by 1 and continues as quickly (cps) as I like up to a channel limit (also configurable) - The Ixia generates a valid SDP but no RTP is generated (although that's certainly possible at these call levels) Two 1 gig ports on the Ixia are connected to the Broadcom NICs on the Dell R610 via a Cisco Catalyst 4948 switch. One port on the Ixia emulates the 100000 agents (A leg) and the other emulates the 200000 agents (B leg). Of course I can provide more information if needed. Here are some test numbers: With TLS at 20cps, 120 sec calls, up to a total of 2470 calls (4940 registrations) life is good. Very good - call setup time averages 23ms, the cps rate holds indefinitely, and not a single call or registration fails over long term tests. UDP and TCP numbers are excellent (bordering ridiculous) - usually around 500cps with practically no reasonable upper limit on simultaneous calls. This doesn't need any further discussion :). The TLS numbers start falling apart pretty quickly after 20cps, however. If I change the TLS test to 40cps, 120 sec calls, up to a total of 4940 calls (9,880 registrations) Kamailio starts to (seriously) struggle. The rate starts fluctuating all over the place, call setup time averages jump to 8000ms (or more) and things just generally get ugly. Interestingly enough all of the user agents are able to register, the logs look fine (to my eye at this log level) and the system (CPU, network, etc) doesn't appear to be under stress at all. I have a few questions: 1) Is there something obviously wrong or stupid I'm doing here? 2) Why are the TLS tests so much worse than TCP and UDP? Am I missing something here? Thanks (in advance) for any advice anyone might be able to offer! -- Kristian Kielhofner

The problem is that if p[1] is negative (-1 is 0xff), then the integral promotion is signed as well and is complementary of 2 (or whatever the implementation considers), and the shift will return another value as expected. For example : #include <stdio.h> int main(){ char b = 0xff; unsigned h = (b<<16); printf("%x\n", h); return 0; } will print ffff0000 instead of ff0000 as expected. Haven't calculated the implication of this related to the bug.

Hello, hmm, hentity is null even a check for its value is done above ... Is this reproducible or happens from time to time? What are the values you set for $avp(s:puburis_caller) and $avp(s:puburis_callee)? Can you try without parameters: modparam("pua_dialoginfo", "use_pubruri_avps", 1) modparam("pua_dialoginfo", "pubruri_caller_avp", "$avp(s:puburis_caller)") modparam("pua_dialoginfo", "pubruri_callee_avp", "$avp(s:puburis_callee)") These were added by a recent contribution, I want to see if they are the reason.

Siremis install fail at last page of web install

by Magnus

Hello all, I have an issue with final stage of installing siremis - at the last screen of the install I get an error in browser of "can't open cmp file to write" in the httpd log I get two lines " mkdir(): No such file or directory in /var/www/html/siremis-3.2.0/openbiz/bin/Resource.php on line 408" and next line of "fopen(/var/www/html/siremis-3.2.0/siremis/files/cache/metadata/CB3F6C48_log Service.cmp): failed to open stream" I have down a chown on the siremis dir to make the web process the owner, and this allowed me to get to the last page of the install, all shows as successful expect instead of a login page I get the error. The server platform is centos if makes any difference. Thanks Magnus
