Hi all, Thanks for the tips. I tried to reinstall my ser. not by rpm file. but compiling source code and make install. Then I met the problem when i running the ser: ================================================== [root@pc5 ~]# /usr/local/sbin/ser : command not found: line 6: : command not found: line 8: : command not found: line 12: /usr/local/sbin/ser: line 13: /bin: is a directory : No such file or directory6: */ : command not found: line 17: : command not found: line 24: : command not found: line 26: : command not found: line 29: /usr/local/sbin/ser: line 30: loadmodule: command not found /usr/local/sbin/ser: line 31: loadmodule: command not found /usr/local/sbin/ser: line 32: loadmodule: command not found /usr/local/sbin/ser: line 33: loadmodule: command not found /usr/local/sbin/ser: line 34: loadmodule: command not found /usr/local/sbin/ser: line 35: loadmodule: command not found /usr/local/sbin/ser: line 36: loadmodule: command not found : command not found: line 37: : command not found: line 42: : command not found: line 44: : command not found: line 46: /usr/local/sbin/ser: line 47: syntax error near unexpected token `"usrloc",' 'usr/local/sbin/ser: line 47: `modparam("usrloc", "db_mode", 0) =================================== but my ser.cfg is already revised to the required one. as: ========================= [root@pc5 ~]# cd /usr/local/etc/ser [root@pc5 ser]# ls dictionary.ser old ser.cfg ser.cfg~ ser.cfg.edited ser.cfg.old ser.cfg.sample [root@pc5 ser]# cat ser.cfg # # $Id: ser.cfg,v 1.25.2.1 2005/02/18 14:30:44 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 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/local/lib/ser/modules/mysql.so" loadmodule "//usr/local/lib/ser/modules/sl.so" loadmodule "//usr/local/lib/ser/modules/tm.so" loadmodule "//usr/local/lib/ser/modules/rr.so" loadmodule "//usr/local/lib/ser/modules/maxfwd.so" loadmodule "//usr/local/lib/ser/modules/usrloc.so" loadmodule "//usr/local/lib/ser/modules/registrar.so" loadmodule "//usr/local/lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! loadmodule "//usr/local/lib/ser/modules/auth.so" loadmodule "//usr/local/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 >= 2048 ) { 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 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); break; }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); 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("iptel.org", "subscriber")) { www_challenge("iptel.org", "0"); break; }; save("location"); break; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; 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(); }; } ================================ Sorry about too much copy files. But could anyone can tell me where the problem is and what the solution?
