[OpenSER-Users] BAsic openSER configuration. INVITES to a UA not looped back.
by Eloi Pecharroman 23 Apr '08

23 Apr '08

Hello, I have been unsuccessfully trying to setup OpenSER as a basic server in my private network. The idea is that clients can register to the virtual domain "sipserver.apt.local" and from then, INVITES will be sent to the appropiate address. I use the following openser.cfg # ----------- global configuration parameters ------------------------ debug=5 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) children=4 log_facility=LOG_LOCAL7 # Uncomment these lines to enter debugging mode #fork=no #log_stderror=yes # port=5060 listen=udp:192.168.100.244:5060 listen=udp:sipserver.apt.local:5060 alias="sipserver.apt.local:5060" sip_warning=yes # 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 = "/etc/openser/tls/user/user-cert.pem" #tls_private_key = "/etc/openser/tls/user/user-privkey.pem" #tls_ca_list = "/etc/openser/tls/user/user-calist.pem" # ------------------ module loading ---------------------------------- #set module path mpath="/usr/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" loadmodule "xlog.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 >= max_len ) { 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("openser.org", "subscriber")) { # www_challenge("openser.org", "0"); # exit; #}; xlog("L_INFO","[ACHTUNG] saved $ru"); save("location"); exit; }; xlog("L_INFO","[ACHTUNG]request from $ru"); #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; } I can register fine, however, on INVITE, openSER forwards it internally instead of fw to the client registered until max_fw reaches 0 and an error "too many hops" is the final response.

[OpenSER-Users] Unregistered users able to make calls
by Aadilkhan Maniyar 22 Apr '08

22 Apr '08

Hi, I have a setup where in Openser is acting as the registrar and Asterisk handles the media. i.e. the INVITEs are relayed to the Asterisk server by Openser. When I try to make a call from an unregistered user the call goes thru. The user is present in the subscriber table but is not registered with Openser at that instant. Is this an expected behavior? If not what needs to be done so that an unregistered user is prohibited from making any calls. Any help would be appreciated. Thanks in advance. Regards, Aadil

[OpenSER-Users] UDP/TCP failover in OpenSER
by Antoine Fressancourt 22 Apr '08

22 Apr '08

Hello list, I have several questions about the support of TCP in OpenSER in general, and about the switch/ failover from UDP to TCP in particular. In my setup, I have several SIP clients registered to a single OpenSER, and they exchange presence messages on a peer-to-peer basis. When the presence document is complex, the size of the message sent exceeds a given limit, and I want my message to be sent over TCP. My clients are registered on the OpenSER, and the REGISTER has been sent over UDP. From now, when client A sends a NOTIFY using TCP to client B, the message is transported over TCP from A to the OpenSER, and is transported over UDP from the OpenSER to B. So here are my questions : - How can I tell OpenSER to relay the message to B using TCP ? - Do I have something particular to do while registering to tell OpenSER that the client is listening in UDP and TCP ? Thank you in advance for your answers, Antoine

[OpenSER-Users] Openser ignoring SIP version in the Request Line
by Aadilkhan Maniyar 22 Apr '08

22 Apr '08

Hi, When Openser receives a malformed INVITE with SIP version set to 10.0 in the Request Line, it just processes it as a normal INVITE. The Request Line of the INVITE message received looks like this: INVITE sip:ua1@domain.com SIP/10.0 According to RFC 3261, the Requests should contain SIP/2.0. Hence Openser should drop this request with an appropriate 4xx reponse. But this behavior is not seen. Do I have to modify my openser.cfg for validating the above INVITE? Any help would be appreciated. Thanks, Aadil

[Serusers] rewriting to a dns domain
by Rolf Unger 22 Apr '08

22 Apr '08

Hello list users, i want to use ser as a load balancing proxy for some PSTN gateways that I have in use. My idea is to use the rewritehost() core function and DNS SRV entries to accomplish this. But it seems that ser is doing a A record lookup if I simply replace the host with my domain "mynet.interx": if ( ... ) { rewritehost("mynet.interx"); t_relay(); } Ser is running on the same host (89.49.16.54) as the authorative nameserver for the mynet.interx domain. dig shows that the DNS files are configured in the right way for load balancing, but I just can't find a way to make ser as a dns client work like dig. If I use "_sip._udp.mynet.interx" it will complain about a bad name. Well he is partly right, underscores are not allowed in domain names. And if I use only the domain in the rewrite command it will contact the IP of the nameserver of this domain. Or in other words it will send the messages to itself. Using directly rewritehost("sip1.mynet.interx") doesn't help me, because it wouldn't do load balancing. How can I convince ser (version 0.9.6) to use the correct lookup method for the DNS? Any hints are appreciated ... Thanks, Rolf. ---------------------------------------------------------------- ; <<>> DiG 9.2.4 <<>> -t SRV _sip._udp.mynet.interx ;; QUESTION SECTION: ;_sip._udp.mynet.interx.

[OpenSER-Users] Call setup authentication through openLDAP
by Ahmed Huraimel 22 Apr '08

22 Apr '08

Dear all, I wounder if anyone successfully uses openSER 1.3.x with LDAP server (openLDAP). For me I work fine with Authenticating the uses while REGISTER request. However, I could not configure it to Authenticate call setup. in other words, an non register user can make a call setup. what comes to my mind is to use the same idea of authentication when RIGISTER request was issues with some modefications but when SIP proxy server send "407 Proxy Authentication Required" the client send ACK and stop. ================================================= # account only INVITEs if (is_method("INVITE")) { xlog("L_NOTICE","Processing by INVITE handler ...\n"); route(4); exit; #setflag(1); # do accouting } ..... route[1] { if (!t_relay()) { sl_reply_error(); }; exit; } .......... rout[4] { if(is_present_hf("Authorization")) { # ldap search if (!ldap_search("ldap://sipaccounts/ou=sip,dc=mysip,dc=com?sn,userPassword?one?(cn=$fU)")) { switch ($retcode) { case -1: # no LDAP entry found sl_send_reply("404", "User Not Found"); exit; case -2: # internal error sl_send_reply("500", "Internal server error"); exit; default: exit; } } ldap_result("sn/$avp(s:username)"); ldap_result("userPassword/$avp(s:password)"); if(!pv_proxy_authorize("")) { proxy_challenge(""/*realm*/,"0"/*qop*/); exit; } route(1); } else { proxy_challenge("","1"); exit; } ================================================= do any one know how to authenticate call setup? do you think using RADIUS is better for authentication instead of LDAP authentication? regards, Ahmed ALALI
