[Serusers] Performance tuning
by zeusng 28 Mar '04

28 Mar '04

Can anyone give me a realistic test case for measuring SER performance? I've been using sipsak to stress my SER server but am not able to interpret the result. Here are some sipsak were run: [siptest@sipuat siptest]$ sipsak -U -I -e 10000 -s sip:40@mysip.test -r 5060 -n 800 -z -vv [siptest@sipuat siptest]$ sipsak -U -I -e 50000 -s sip:30@mysip.test -r 5060 -n 2 -z -vv [siptest@sipuat siptest]$ sipsak -U -I -e 10000 -s sip:40@mysip.test -r 5060 -n 150 -z -vv [siptest@sipuat siptest]$ sipsak -U -I -e 10000 -s sip:40@mysip.test -r 5060 -n 50 -z -vv One of the result as follow: All usrloc tests completed successful. received last message 109125.023 ms after first request (test duration). biggest delay between request and response was 46082.422 ms 10 retransmission(s) received from server. 9 time(s) the timeout of 5000 ms exceeded and request was retransmitted. I guess a delay of 46s (46082.422ms) is definitely not acceptable. What should I set for -n to be comparable to real world traffic. And what kind of result should I expect. Side issue: During my stress test, I experience the same problem Andres reported last Nov. udp_rcv_loop:recvfrom:[11] Resource temporarily unavailable After I modify some kernel (Fedora Core 1, Linux 2.4.22) parameters, the problem seems to go away. Anyone happy to prove the case? # echo "8388608" > /proc/sys/net/core/rmem_max # echo "8388608" > /proc/sys/net/core/wmem_max # echo "8388608" > /proc/sys/net/core/rmem_default # echo "8388608" > /proc/sys/net/core/wmem_default Zeus ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

[Serusers] SER and MSN Configuration Help
by Chris Bookholt 28 Mar '04

28 Mar '04

Greetings, I'm a new SER user trying to set up a very basic SER configuration with a proxy server and two SIP clients. I'm running SER on RedHat Linux 7.3 and a pair of MSN 4.6 clients. I have set up SER with MySQL and digest authentication support (see of of message for ser.cfg) and added a handful of normal users to the ser MySQL db using serctl. The two clients can sign on and communicate with each other. However, the weirdness started after I added each client to the other's buddy list. Even though both users are online and could IM each other, only one of the users were shown as online on the other user's buddy list. The factor that determines which client is visible in a buddy list seems to be the order in which the users sign on. Another issues is that a non-existent user can login. That is, a user that does not have any entry in the ser MySQL database can still login and communicate with other users online. How do you enforce authentication? I'd also be happy to learn of any alternatives to MSN that run on either Windows of GNU/Linux. Any help you can provide would be appreciated. Thanks in advance. Best Regards, Chris B. P.S. - I did search the serusers archive using Google and it seemed that a similar question had been brought up in the past, but I found no answer. My apologies if I was too hasty in my search of the archives. --- ser.cfg --- # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode debug=7 fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) #port=5060 #children=4 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/ser/modules/mysql.so" loadmodule "/usr/lib/ser/modules/sl.so" loadmodule "/usr/lib/ser/modules/tm.so" loadmodule "/usr/lib/ser/modules/rr.so" loadmodule "/usr/lib/ser/modules/maxfwd.so" loadmodule "/usr/lib/ser/modules/usrloc.so" loadmodule "/usr/lib/ser/modules/registrar.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/lib/ser/modules/auth.so" loadmodule "/usr/lib/ser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- #modparam("usrloc", "db_mode", 0) # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line modparam("usrloc", "db_mode", 2) # -- auth params -- # Uncomment if you are using auth module # modparam("auth_db", "calculate_ha1", yes) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- # main routing logic route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol record_route(); # loose-route processing if (loose_route()) { t_relay(); break; }; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri=~"team3") { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("team3", "subscriber")) { www_challenge("team3", "0"); break; }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); }; }

[Serusers] SER with Multiple Contact
by Marc LIVET 27 Mar '04

27 Mar '04

Hi all, I've configured a local SER on our network, and I met some difficulties with multiple Contacts. When UA1 changes IP address, and REGISTER in SER to announce his new IP, both last and New Contacts are placed in Location table, with different 'expires' values. If UA2 receives last UA1 IP address, and REGISTER with it, calling UA1 from UA3 when both Contact still available, makes UA2 ringing, which cause some confusion. To overcome about this, I'm searching for a way to force SER to delete an "old Contact" when a Registration is done with same URI and different IP; That way, only one Contact for one URI is available. I've tried to add modparam("registrar", "append_branches", 0) in ser.cfg, but in this case, Contact with lowest 'expires' parameter is called, and not Contact with highest one, still causing confusion fo IP calls. Could anyone tell me how to force a Contact to be deleted in SER location table, in case of registration with new Contact? Thanks for your support. Regards. Marc
