RE: [Serusers] SER installation, allows signin, but can't see any one else
by Morris, Scott 09 Jul '03

09 Jul '03

That worked, however, SER doesn't answer any sign-ins. There has to something very easy here where a person signed-in isn't seeing anyone else signed in. Any thoughts?

This will stop ser from becoming a daemon and detaching and it will block your booting process (on most distributions). dont_fork is only for debugging, which means manually starting ser, from a terminal.

[Serusers] nathelper and rtpproxy problem
by Klaus Darilion 09 Jul '03

09 Jul '03

Hi! I have tried ser + nathelper + rtpproxy: Following configuration: Clients inside NAT: IP 192.168.0.x Windows Messenger NAT-Box: old mandrake linux (2.2 kernel) + ser (cvs from 7.7.03) + rtpproxy (08-Jul-2003). local interface: 192.168.0.1 global interface: mydomain.dyndns.org ser and the rtpproxy are running. The clients register at ser (sip:klaus@mydomain.dyndns.org). 1. I can receive incoming calls (signaling and rtp works fine). But in the outgoing messages, ser adds a via header with the local IP address (192.168.0.1) instead of the global IP address. How can I configure this in ser.cfg? 2. The rtpproxy starts relaying after RTP packets from both sides are received. That causes problems if the clients use silence suppression (like Messenger): I call my friend (I am quiet, so no RTP packets will be sent).... the friend answers: "Hello!" ... both the rtpproxy doesn't relay, so I don't answer .... my friend again "HELLO" ... the rtpproxy still doesn'relay, so I don't answer..... and so on. So, I suggest the rtpproxy should start relaying immediately. regards, Klaus my ser.cfg (the default cfg file + the routing from the nathelper_rtpp.cfg): -------------------------------------------------- # # $Id: ser.cfg,v 1.21 2003/06/04 13:47:36 jiri 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=mydomain.dyndns.org # ------------------ 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/nathelper.so" loadmodule "/usr/local/lib/ser/modules/textops.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" # 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 (len_gt( max_len )) { 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 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("iptel.org", "subscriber")) { # www_challenge("iptel.org", "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(); }; } #inserted by klaus # all incoming replies for t_onrepli-ed transactions enter here onreply_route[1] { if (status=~"2[0-9][0-9]") force_rtp_proxy(); }

[Serusers] SER installation, allows signin, but can't see anyone else
by Morris, Scott 08 Jul '03

08 Jul '03

I have 0.8.11pre29 installed on Redhat 8.0. Also have MySQL installed and working, so my users have been declared "persistant". I can sign-in, but cannot see any of my contacts that are signed-in. If I go to the server, I can see the list of those signed-in. I tried to change the ser.cfg file for debugging, but then SER won't start up, and the server hangs at "Starting SER". I can't go any further at the console, I have ssh in and kill then process then reboot. Scott Morris Senior Network Engineer ORAU / ORISE 865-576-4672 'B' Schedule

[Serusers] Re: adding a header
by Mario Kolberg 08 Jul '03

08 Jul '03

Andrei, thanks very much! I have now taken Jiri's advice and use the textops package to add the header. However, in the package, I'm calling append_hf with the message and a char* which is the new header. From the look of it, it seems that append_hf should call str_fixup for the char*. This does not seem to happen. I included some debug messages and str_fixup is not called. Thus, the length of the string in append_hf_helper is just garbage. I have included an explicit call to str_fixup in append_hf and then everything works fine. I'm not sure how exactly the cmd_export_t structure is working - for append_hf it lists str_fixup. Thanks again for your help!

[Serusers] Accounting with SER
by Director General: NEFACOMP 08 Jul '03

08 Jul '03

I would like to get more information on accounting with SER. Ok, I followed the documentation about accounting but it doesn't give enough information about how to retrieve the accounting information. It just says that Reports are by DEFAULT sent to the syslog facility. Where is that syslog? How do I retreive that information? Is it possible to put that information in the MySQL database? How? That is by DEFAULT; so, is it possible to change that default location? Some gurus will realize how NEWBIE I am in the Linux World. Please help me.

While trying to use the command for adding an alias, the computer tells me that the aliases table was not found. But I can see the aliases table in the database. What do you think might be wrong?
