[Serusers] SER Authentication Prob

Hi all, Hope somebody can help-I really am stumped as to why this won't work and would really appreciate if someone could shed some light on the problem.... I currently have SER set up and clients are registering successfully. However I want clients to authenticate before they can register. Howevere when I uncomment the relevant lines in the ser.cfg file, my clients can't register. The only thing I can think of is that SER is behind NAT and my clients may/may not be behind NAT....I have included my ser.cfg file below...I have spent along time trying to understand why this is happening so any help will be appreciated! Thanks, Aisling. # # $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" alias=84.203.148.14 # ------------------ 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" loadmodule "/usr/lib/ser/modules/nathelper.so" #loadmodule "/usr/lib/ser/modules/mediaproxy.so" loadmodule "/usr/lib/ser/modules/textops.so" #loadmodule "/usr/lib/ser/modules/maxfwd.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) #!!Nathelper #modparam("registrar","nat_flag",6) #modparam("nathelper","natping_interval",30) #Ping intervals 30 seconds #modparam("nathelper","ping_nated_only",1) #Ping only clinets behind NAT # -------------------------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; }; #############Aisling Insert################ # #!Nat Insert # #the below line tests if the IP of the received packet is different from the IP in the via header and also # #sees if the IP address in the contact header is private # if (nat_uac_test("3")){ # if (method == "REGISTER" || ! search("^Record-Route:")){ # log("Log: Someone trying to register from private IP,rewriting\n"); # # fixed_nated_contact(); #Rewrite contact with source IP # if (method == "INVITE"){ # fix_nated_sdp("1"); #Add direction=active to SDP # }; # force_rport(); # Add rport parameter to topmost Via # setflag(6); # Mark as Nated # }; # }; ###################End##################### # 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(); # 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==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("84.203.148.14", "subscriber")) { # www_challenge("84.203.148.14", "0"); # break; # }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; #inserted by klaus if (method == "INVITE"){ record_route(); force_rtp_proxy(); /* set up reply processing*/ t_on_reply("1"); }; # 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(); }; } #insert by klaus onreply_route[1]{ if (status=~"[12][0-9][0-9]") force_rtp_proxy(); } #route[1] #{ #if client or server know to be behind NAT, enable relay # if (isflagset(6)){ # force_rtp_proxy(); # }; # # #NAT processing of replies; apply to all transaction (for example, # #reinvites from public to private UA are hard to identify as # #Nated at the moment of request processing); look at replies # t_on_reply("1"); # # #send it out now; use stateful forwarding as it works reliably # #even for UDP2TCP # if(!t_relay()){ # sl_reply_error(); # }; #} #!!NatHelper #onreply_route[1]{ #Nated Transaction??
