Re: [OpenSER-Users] Unauthorized Calls - [Openser - X-lite]

Hello DanB, Thanks! As DanB´s suggestion, I tried to implement a mechanism that only allowed authenticated members make calls, but my configuration didn´t function. This is my first project with openser, therefore I do not have much experience. If someone know how to help me to implement this verification, I will be very thankful. Below, my openser.cfg file: -x-x-x-x-x-x-x-x-x-x-x-x-x-x-x-x -x-x-x-x-x-x-x-x # ----------- global configuration parameters ------------------------ debug=3 fork=yes log_stderror=no log_facility=LOG_LOCAL7 # hostname matching an alias will satisfy the condition uri==myself". alias=xxx.xxx.xxx.xxx listen=udp:xxx.xxx.xxx.xxx:5060 # check_via - Turn on or off Via host checking when forwarding replies. # Default is no. arcane. looks for discrepancy between name and # ip address when forwarding replies. check_via=yes # syn_branch - Shall the server use stateful synonym branches? It is # faster but not reboot-safe. Default is yes. syn_branch=yes # dns - Uses dns to check if it is necessary to add a "received=" field # to a via. Default is no. # rev_dns - Same as dns but use reverse DNS. dns=no rev_dns=no port=5060 children=4 # memlog - Debugging level for final memory statistics report. Default # is L_DBG -- memory statistics are dumped only if debug is set high. memlog=3 # sip_warning - Should replies include extensive warnings? By default # yes, it is good for trouble-shooting. sip_warning=yes # fifo - FIFO special file pathname fifo="/tmp/openser_fifo" # reply_to_via - A hint to reply modules whether they should send reply # to IP advertised in Via. Turned off by default, which means that # replies are sent to IP address from which requests came. reply_to_via=no # mhomed -- enable calculation of outbound interface; useful on # multihomed servers. mhomed=0 # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database loadmodule "/usr/lib/openser/modules/mysql.so" loadmodule "/usr/lib/openser/modules/sl.so" loadmodule "/usr/lib/openser/modules/tm.so" loadmodule "/usr/lib/openser/modules/rr.so" loadmodule "/usr/lib/openser/modules/maxfwd.so" loadmodule "/usr/lib/openser/modules/usrloc.so" loadmodule "/usr/lib/openser/modules/registrar.so" loadmodule "/usr/lib/openser/modules/textops.so" loadmodule "/usr/lib/openser/modules/nathelper.so" loadmodule "/usr/lib/openser/modules/acc.so" loadmodule "/usr/lib/openser/modules/xlog.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "/usr/lib/openser/modules/auth.so" loadmodule "/usr/lib/openser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- # ------------- usrloc parameters # 2 enables write-back to persistent mysql storage for speed # disable=0, write-through=1 modparam("usrloc", "db_mode", 0) # minimize write back window - default is 60 seconds modparam("usrloc", "timer_interval", 30) # ------------- auth parameters # 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 parameters # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------- !!
