Hello All, My task is to program the ser.cfg in a way that it connects to an external database(any machine in LAN,other than the server on which SER is running) After getting connected to the database I need to query the database and get a result set of IPAddresses based on the destination number that I passed in the query..and further use this set to rewrite the call to the IP Address retrieved. To accomplish this task I need-- 1.how to extract the destinationno from sip_uri 2.how to use the database interface given in SER programmer's guide I went through SER programmer's guide,but if anybody can provide me a simple example of using database interface,it wud be of great help. Thanks!

RE: [Serusers] Trusted IP and security.

by Tom Lowe

Hi Jamey, and Kiss, who answered in another message. Thanks for the feedback. I'm not worried about someone on the networks local to the proxy server, so that won't be an issue. As far as getting into a router between the user agent and proxy, I believe it would have to be positioned such that they can redirect packets destined for the "spoofed" IP, and I don't that's too likely....though definitely something to look at. Sending the invite with a spoofed IP would certainly be a potential DOS type of attack, and one I'm concerned about But what I am looking to prevent is someone making 'successful' phone calls that are billed to another customer based on IP address, so I believe both of you have basically confirmed my thinking...that someone can't easily spoof IP's from outside the local network and make successful usable calls. I'll check out the articles Jamey recommended. If anyone else has comments, I'd love to hear them! Thanks again!

This could not be detected from SER because responses would actually be routed to the attacker. ARP poisoning hijacks an IP address at the link layer. Here are two articles that describe it and how to detect it and to protect against it: http://www.watchguard.com/infocenter/editorial/135324.asp http://www.sans.org/rr/whitepapers/threats/474.php Non-local attackers could get SER to deliver SIP messages for them by sending UDP/SIP packets with forged source IP addresses, but the attacker would not receive the responses and so should not be able to complete the INVITE/OK/ACK transaction unless they can predict the connection and header values that would be provided by the callee. If the trusted IP addresses are local, these SIP messages could be detected and dropped by an ingress filter that packets entering the network do not have source IP addresses within the network. Hope this helps, Jamey

by Matt Schulte

Has anyone else had the FROM: line changed to what's in the TO: after using digest auth between Asterisk and SER? I believe asterisk is the culprit, I opened a ticket on their bugtracker. Matt

by Chris

This seems to be a perennial trouble for people. I see many similar threads. I have 0.9.0 serweb version from when I previously downloaded 08.14 ser is running with mysql, registration and calls running ok etc serweb start up as far as the admin login screen admin/heslo and anything else I throw at it fails to login. It just returns to login screen. After failed login I get a little message : error in sql query line 30 which is the line of the print for error in ….. I have seen many many reports of this but no confirmation from any one that any of the suggested fixes actually did so… Is this a known problem Is it a compatibility issue with 090 Anyone have a solution? Cheers Chris _____ Hi, This is my first time installation of serweb on Fedora Core 2. When I view it from my own linux box and type in username: admin password: heslo Nothing happen. But when I use I.E. on other computers, I see the error message: Bad username and password. I have set php.ini register_globals = on already. I have also restarted httpd. What is my problem?

[Serusers] Stop Radius Accounting on Status 404.

by Mohamed Omar

How can make SER flags status 404 for accounting and send a stop accouting record to the radius server? Am currently doing accounting for calls going to PSTN network and it's working fine if the call is not completed and if I get an error like status 404 then no stop accounting record is sent to the radius server. I would like to force SER to send stop accouting flag to radius server. Can I do this on SER 0.8.14 if (!lookup("location")) { setflag(1); # doesn't seem to be needed, problably because sl_send_reply # acc_rad_request("stop"); sl_send_reply("404", "Not Found"); break; Thanks.
