[Serusers] ser 0.9.6 memory problems
by Mitya 31 Oct '07

31 Oct '07

Hi All, I have a SER 0.9.6, and sometimes I have memory allocation problem somehow :( Oct 29 19:58:38 sip ser[23161]: processing REGISTER received from x.x.x.x Oct 29 19:58:38 sip ser[23161]: DEBUG: t_newtran: msg id=23950 , global msg id=23949 , T on entrance=0xffffffff Oct 29 19:58:38 sip ser[23161]: parse_headers: flags=-1 Oct 29 19:58:38 sip ser[23161]: DEBUG: get_hdr_body : content_length=0 Oct 29 19:58:38 sip ser[23161]: found end of header Oct 29 19:58:38 sip ser[23161]: parse_headers: flags=60 Oct 29 19:58:38 sip ser[23161]: t_lookup_request: start searching: hash=31874, isACK=0 Oct 29 19:58:38 sip ser[23161]: DEBUG: RFC3261 transaction matching failed Oct 29 19:58:38 sip ser[23161]: DEBUG: t_lookup_request: no transaction found Oct 29 19:58:38 sip ser[23161]: ERROR: sip_msg_cloner: cannot allocate memory Oct 29 19:58:38 sip ser[23161]: DEBUG:destroy_avp_list: destroying list (nil) Oct 29 19:58:38 sip ser[23161]: ERROR: new_t: out of mem: Oct 29 19:58:38 sip ser[23161]: ERROR: t_newtran: new_t failed As I read in the mailing lists, it occurs, when SER has a lots of live, opened transactions. It's a test SER, I think we did not have any opened transactions (maybe the failed ones). Is there any mechanism in SER, what drops the too old opened (most likely failed transactions) transactions ? Can I get the current used shared memory somehow ? What else can sause this problem ? Thanks, Mitya

[OpenSER-Users] port modification is sdp
by Konstantinos Koutsopoulos 31 Oct '07

31 Oct '07

Hi, I am deploying openser 1.2.2-notls on a machine with public IP. On the same machine I run a sip client (A) that registers with the above openser. On an another machine behind NAT (typical adsl router) I use a sip client (B) to register with the above openser and try to invite sip client A. I do not use any NAT-traversal techniques (the outgoing packets from B are modified by NAT and reach openser, responses are received by B through NAT due to statefull (?) routing on the NAT). The SIP messages reach their destination properly and moreover the IP addresses in the SDP (from B) are updated by openser to indicate the external interface of NAT. This is very useful in my case since the client A sends the media packets to the proper address (I also configure virtual servers on the adsl router to have these forwarded to B). However, the port numbers in the SDP are also updated (usually by an offset of +16) which hinders the media session from A to B since B is expecting the packets on other ports. Is there any way to have the ports remain unaltered during the above operation? Thanks in advance, Kostas Below is my openser.cfg # # $Id: openser.cfg 1676 2007-02-21 13:16:34Z bogdan_iancu $ # # simple quick-start config script # Please refer to the Core CookBook at http://www.openser.org/dokuwiki/doku.php # for a explanation of possible statements, functions and parameters. # # ----------- global configuration parameters ------------------------ debug=3 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) children=4 # Uncomment these lines to enter debugging mode #fork=no #log_stderror=yes # port=5060 # uncomment the following lines for TLS support #disable_tls = 0 #listen = tls:your_IP:5061 #tls_verify_server = 1 #tls_verify_client = 1 #tls_require_client_certificate = 0 #tls_method = TLSv1 #tls_certificate = "/opt/openser/etc/openser/tls/user/user-cert.pem" #tls_private_key = "/opt/openser/etc/openser/tls/user/user-privkey.pem" #tls_ca_list = "/opt/openser/etc/openser/tls/user/user-calist.pem" # ------------------ module loading ---------------------------------- #set module path mpath="/lib/openser/modules/" # Uncomment this if you want to use SQL database loadmodule "mysql.so" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "mi_fifo.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "auth.so" loadmodule "auth_db.so" # ----------------- setting module-specific parameters --------------- # -- mi_fifo params -- modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo") # -- 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"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; # 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 if (!method=="REGISTER") record_route(); # subsequent messages withing a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); # if you have some interdomain connections via TLS #if(uri=~"@tls_domain1.net") { # t_relay("tls:domain1.net"); # exit; #} else if(uri=~"@tls_domain2.net") { # t_relay("tls:domain2.net"); # exit; #} route(1); }; # 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==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication if (!www_authorize("......", "subscriber")) { www_challenge(".....", "0"); exit; }; save("location"); exit; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); exit; }; append_hf("P-hint: usrloc applied\r\n"); }; route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; }

[Serusers] lcr module error - no prefix column and no avp visible
by Tomasz Zieleniewski 31 Oct '07

31 Oct '07

Hi, During the lcr module set up I encountered the following problems: a) there is no prefix column in the gw table so when the modules is initialized it returns an error b) the ip_addr column in gw table is an int(1o) type how should I specify it to get the IP like 192.168.0.74? c) when I invoke the load_gw() there is the debug info that gw_uri_avp was created but when I then try to print it I get that avp not found, what is wrong? log below: Oct 31 11:38:24 sen ser[12273]: load_gws(): DEBUG: Added gw_uri_avp < sip:touk1@138.64.116.11:5070> Oct 31 11:38:24 sen ser[12273]: AVP '$gw_uri_avp' not found Waiting for Your feedback Regards Tomasz

[OpenSER-Users] Generating an INVITE with multiple Contacts
by Juan Carlos C. y Castro 31 Oct '07

31 Oct '07

(Please CC me as I'm not on the list) Hello, I'm having an OpenSER installation being submitted to a compliance test, and one of the many tests requires that OpenSER replies to a correctly authenticated REGISTER with many Contact headers with 200 OK messages for each of the contacts, in addition to storing all the contacts in the location database. Questions: 1) Do I need some special configuration for that? Shouldn't the radius_www_authorize() function (I'm authenticating against Radius) take care of it all? 2) What software could I use to generate a REGISTER request with multiple Contacts? Thanks, Juan

[OpenSER-Users] OpenXcap exception: TypeError in twisted.web2.stream.IByteStream
by Gregorio 30 Oct '07

30 Oct '07

Hi all. I get an exception in openXcap when I send a GET to retrieve the resources file. I explain the process I followed: ----->Send GET to openXcap. <----Receive 404, because there is not file. -----> Send PUT to openXcap. The body contains a resource-list.xml document 'with no data': Body; <?xml version='1.0' encoding='UTF-8'?> <resource-lists xmlns='urn:ietf:params:xml:ns:resource-lists' xmlns:cp='urn:ietf:params:xml:ns:copycontrol'> <list></list> </resource-lists> <----Receive 200 OK. So openXcap likes my document. -----> Send GET to openXcap. <---- Receive 500 "An error occurred rendering the requested page. More information is available in the server log". So the same document that was accepted in the PUT throws an exception. The server log says: Oct 30 15:01:55 localhost openxcap[2791]: [-] Exception rendering: Oct 30 15:01:55 localhost openxcap[2791]: [-] Traceback (most recent call last): Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/twisted/internet/posixbase.py", line 228, in mainLoop Oct 30 15:01:55 localhost openxcap[2791]: [-] self.runUntilCurrent() Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/twisted/internet/base.py", line 533, in runUntilCurrent Oct 30 15:01:55 localhost openxcap[2791]: [-] f(*a, **kw) Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/twisted/internet/defer.py", line 239, in callback Oct 30 15:01:55 localhost openxcap[2791]: [-] self._startRunCallbacks(result) Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/twisted/internet/defer.py", line 304, in _startRunCallbacks Oct 30 15:01:55 localhost openxcap[2791]: [-] self._runCallbacks() Oct 30 15:01:55 localhost openxcap[2791]: [-] --- <exception caught here> --- Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/twisted/internet/defer.py", line 317, in _runCallbacks Oct 30 15:01:55 localhost openxcap[2791]: [-] self.result = callback(self.result, *args, **kw) Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/xcap/resource.py", line 51, in sendResponse Oct 30 15:01:55 localhost openxcap[2791]: [-] response = http.Response(response.code, stream=response.data) Oct 30 15:01:55 localhost openxcap[2791]: [-] File "/usr/lib/python2.4/site-packages/twisted/web2/http.py", line 109, in __init__ Oct 30 15:01:55 localhost openxcap[2791]: [-] self.stream = IByteStream(stream) Oct 30 15:01:55 localhost openxcap[2791]: [-] exceptions.TypeError: ('Could not adapt', array('c', "<?xml version='1.0' encoding='UTF-8'?><resource-lists xmlns='urn:ietf:params:xml:ns:resource-lists' xmlns:cp='urn:ietf:params:xml:ns:copycontrol'><list></list></resource-lists> "), <InterfaceClass twisted.web2.stream.IByteStream>) Anyone know what is wrong?

[OpenSER-Users] OpenXCAP server, twisted or Apache ?
by KevinKinnan 30 Oct '07

30 Oct '07

OpenXCAP has already included twisted, do I need to install Apache? I don't much about twisted. It seems I need to create a directory for xcap root, because the web browser gives me "XCAP root not found for uri: http://127.0.0.1:8000". And, how do I do that? Thank you Kevin, _________________________________________________________________ MSN 中文网，最新时尚生活资讯，白领聚集门户。 http://cn.msn.com

[Serusers] audio and auth problems?
by Max Lock 30 Oct '07

30 Oct '07

Hi Folks, I have 2 questions, I'm using openser 1.1.x and rtpproxy bridging between 2 networks, one public, one private. a pstn gateway in the private network, and clients in the public network. firstly, when I make a call check_from() fails, unless I comment it out, why is this? # if(!check_from()) # { # sl_send_reply("403", "Spoofed From-URI Detected"); # exit; # } and secondly. I have rtpproxy and openser listening on both public and private interfaces, with mhomed=1 set. whenever I make a call, everything works ok, but I have no audio? where should I look? -Cheers Max

[OpenSER-Users] How to compare $si with $dr
by Richard Bennett 30 Oct '07

30 Oct '07

Hi, I am trying to compare the values of 'IP source address' ($si) and 'Domain in SIP Request's URI' ($rd) to see if they match in Openser 1.1. Probably I have missed the relevant documentation, I checked http://www.openser.org/dokuwiki/doku.php/pseudovariables:1.1.x and http://www.openser.org/dokuwiki/doku.php/core-cookbook:1.1.x . Basically I'd like to do this: if($si == $rd){ #do something } but that gives a syntax error. I also tried this: if(src_ip==$rd){ } but it seems the pseudo variable isn't being expanded before the evaluation, as I don't get a match even though debugging shows $si and $rd to be the same. Also, is there anyway to pass a pseudo variable to rewritehost() or an equivalent function? Thanks for any pointers, Richard
