I have a little problem, i need to force the UA (outside NAT with public IP address) to send the BYE messages to my Sip Server so I can account them in the acc table. I use record_route() to acomplish that but the thing is the Record-Route field in the message that an UA recieve, the IP address is the SIP SERVER LOCAL IP ADDRESS BEHIND NAT (Record-Route: <sip:5000022@192.168.0.2;ftag=192550680;lr=on>) which means, of course, that the message will not pass trough the SIP Server. How Could i force the server to write in the Record-Route field the valid IP address of my Sip Server (200.24.99.131)???? Example message sent by the Sip Proxy: RECEIVE TIME: 1420109 RECEIVE << 200.24.99.131:5060 SIP/2.0 180 Ringing Via: SIP/2.0/UDP 200.71.103.253:5060;rport=5060;branch=z9hG4bK725C92055C654839934F043974F39E1F From: Andres Parra <sip:3304076@ipsofactum.com>;tag=192550680 To: <sip:5000022@ipsofactum.com>;tag=2391513217 Contact: <sip:5000022@68.38.237.35:32805> Record-Route: <sip:5000022@192.168.0.2;ftag=192550680;lr=on> Call-ID: 31517648-DF5F-4A12-BE74-5B1026B4C39D(a)200.71.103.253 CSeq: 29855 INVITE Server: X-Lite release 1103m Content-Length: 0 Ser.cfg: # # $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" # ------------------ 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" # Uncomment this if you want digest authentication # mysql.so must be loaded !

[Serusers] SER With FreeRadius

by jawad bokhari

I installed freeradius-0.9.1 to work with SER 0.8.14. They gave a test example to add a user in users file with following contents: test Auth-Type := Digest, User-Password == "test" Reply-Message = "Hello, test with digest" But when I run radius with "radiusd -X", it gives following error: /usr/local/etc/raddb/users[75]: Parse error (check) for entry test: Unknown value Digest for attribute Auth-Type Errors reading /usr/local/etc/raddb/users radiusd.conf[921]: files: Module instantiation failed. Any idea about this.... Thanks, Jawad __________________________________ Do you Yahoo!? Y! Messenger - Communicate in real time. Download now. http://messenger.yahoo.com

[Serusers] Preventing DoS Attack with SER

by Gerhard Zweimueller

Hi list, the RFC 3161 gives a chapter about DoS attacks in section 26.3.2.4: [...] No matter what security solutions are deployed, floods of messages directed at proxy servers can lock up proxy server resources and prevent desirable traffic from reaching its destination. There is a computational expense associated with processing a SIP transaction at a proxy server, and that expense is greater for stateful proxy servers than it is for stateless proxy servers. Therefore, stateful proxies are more susceptible to flooding than stateless proxy servers. UAs and proxy servers SHOULD challenge questionable requests with only a single 401 (Unauthorized) or 407 (Proxy Authentication Required), forgoing the normal response retransmission algorithm, and thus behaving statelessly towards unauthenticated requests. Retransmitting the 401 (Unauthorized) or 407 (Proxy Authentication Required) status response amplifies the problem of an attacker using a falsified header field value (such as Via) to direct traffic to a third party. [...] However I tested with a SIP-UA that in case of a wrong password in the INVITE continously tries to register at the same SIP-Registrar (SER in my case). SER in the default stateful configuration of course answers every single INVITE message with 401. No matter how often it comes. Is there a way of prohibiting subsequent 401 answers to "false" INVITEs from the same contact/endpoint or credentials for a defined period, e.g. 30 seconds in SER? Thanks in advance for your help!

[Serusers] Mediaproxy Problem

by Ricardo Martinez

Hi. When i try to make a call in a NAT enviroment i get the next error in the debug from my SER. 1(2825) error: mediaproxy/sendMediaproxyCommand(): can't connect to MediaProxy I guess this is because the mediaproxy is not running, but i followed all the steps in the INSTALL file to start the mediaproxy. I used : /etc/init.d/mediaproxy start and even [root@sipproxy mediaproxy]# ./mediaproxy.py File "./mediaproxy.py", line 84 print >>sys.stderr, "Mediaproxy error: %s. Exiting." % why ^ SyntaxError: invalid syntax [root@sipproxy mediaproxy]# But i can't see any "mediaproxy" process running. Any ideas? Any help will be accepted. Thanks in advance. Ricardo

[Serusers] What happens to ser if MySQP is write-locked briefly

by Gerhard Zweimueller

Hi list, the subject says it all: What happens to the state of ser, when I briefly write-lock the attached MySQL-database to make a file-copy. Briefly meaning 0.5 to 2 seconds. Are requests simply delayed or can serious errors occur?
