Hello, I read moany posts but cannot resolve my problem with ser... here it is (i've changed my real ip and domain name) slackware 10 (actually it is current) ser-08.12 my ser.cfg # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ check_via=no dns=yes rev_dns=yes port=5060 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- 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/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" # -- usrloc params -- modparam("usrloc", "db_mode", 2) modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") modparam("rr", "enable_full_lr", 1) listen=mydomain.org listen=213.213.213.213 # ------------------------- request routing logic ------------------- route{ 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; }; record_route(); if (loose_route()) { t_relay(); break; }; if (uri==myself) { if (method=="REGISTER") { # if (!www_authorize("mydomain.org", "subscriber")) { # www_challenge("mydomain.org", "0"); # break; # }; save("location"); break; }; if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; if (!t_relay()) { sl_reply_error(); }; } Everything seems to be ok and no error messages in /var/log/syslog /var/log/messages Jul 27 14:10:39 sf /usr/local/sbin/ser[xxx]: INFO: signal 15 received Something in /var/lib/mysql/myhost.err 040727 14:07:01 Aborted connection 1480 to db: 'ser' user: 'ser' host: `localhost' (Got an error reading communication packets) 040727 14:07:01 Aborted connection 1485 to db: 'ser' user: 'serro' host: `localhost' (Got an error reading communication packets) But messages go only when I stop ser. SO the problem is that - I use X-Lite sip phone, I login and everything is ok but when I try to call another user typing user2(a)mydomain.org I got message Call Failed: 404 Not Found. User2 is logged in too. Here I use user from internal network but whatever user log in even with real ip ... same problem. serctl moni: ...
