My question: could anyone suggest how to prevent a UAC which is sending some weird data from causing the server to choke? Thanks Cameron

hi all I am trying to develop the interface between PNA and PS,that is PEN interface, for that i am using the one openser 1.2 as the PNA Application server and Presence server. I already developed sh interface between HSS and the PNA. After getting the PNR request from HSS,PNA has to send the PUBLISH message to PS so here my doubt is 1.How to connect the PNA and PS 2.how to construct PUBLISH XML body 3.can i use the opensips/openser as presence network agent thank you regards suresh

Re: [Kamailio-Users] what is the best solution NAT problem

Sunday, October 12, 2008 3:43:16 PM Iñaki Baz Castillo wrote: OpenSer behind a NAT router with dynamic IP? It's really an annoying scenario. Note that when the INVITE/200/(ACK) comes from the LAN 192.168.10.X and goes through OpenSer, you must replace the media IP in the SDP and the IP in "Contact" with the **public** IP of the LAN router, that is a dynamic IP and AFAIK it's not valid to set a domain in the SDP. And when he INVITE/200/(ACK) comes from Internet and goes through OpenSer, you must replace the media IP in the SDP and IP in "Contact" with the eth1 IP of RtpProxy (19.168.10.1). Iñaki I am replacing it for the private ip that I obtain of my router adsl 192.168.1.64, in some examples I read that they replace for the ip it public.. what you try to say is that it replaces the ip that comes from the router for the ip of the lan Also, you need the SIP ports and RtpProxy media ports redirected in the router to the RtpProxy server. that already has it configured in my router ... Anyway, this scenario is not appropiate for a businnes service. you are right, I have a wall of NAT I have open the ports UDP 5060:5065, 10000:20000, 35000:65000 TCP: 5060 Why do you open all these ports? and what do you mean with "open"? don't you mean "redirected"? excuse me, I meant that the ports this redirect to my server PD: A suggestion: Buy an space in a datacenter (a virtual machine could be enough depending on your traffic ammount) and install the OpenSer and RtpProxy decently in a host with public IP. ;) best regards .. rickygm

[Kamailio-Users] How to handle DoS attack and OpenSER Pike module!
by Arif-Uz-Zaman 14 Oct '08

14 Oct '08

Hi all, I need to bother about crazy client by considering "Flood" detection technique. I can do it by using OpenSER Pike <http://kamailio.org/docs/modules/1.2.x/pike.html> module which helps to keep trace of all (or selected ones) incoming request's IP source and blocks the ones that exceeded some limit. In my case: If the number of SIP messages from a single IP address to my SIP Proxy exceeds 200 per minute. Recommended action: Block IP for 2 hours. I tried with the pike module but I'm little bit confused with sampling, density, and timeout value. Please help me with example configuration by considering my point. Thanks, ARIF

[Serusers] ser-0.9.6: modules/postgres bugreport & patch
by Alexandre Snarskii 13 Oct '08

13 Oct '08

Hi! I'm running ser-0.9.6, on FreeBSD 6.1-stable, database backend is postgresql version 8.1.3. Today I got errors in logfiles, saying: messages.2.bz2:May 29 14:35:03 <XXX> /usr/local/sbin/ser[51448]: ERROR:avpops:dbrow2avp: dbrow contains NULL fields The similar problem reported in: http://lists.iptel.org/pipermail/serusers/2005-May/019681.html with much more detailed description of error, database contents and config samples. Patch is trivial, and looks more like a fix to copy'n'paste error: in mysql/val.c function str2val states: if (!_s) { memset(_v, 0, sizeof(db_val_t)); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } VAL_NULL(_v) = 0; and the last line mentions that 'well, that's value is not NULL'. In postgresql/db_val.c, line 182, function str2valp, the same statement is the: if (!_s) { DLOG("str2valp", "got a null value"); VAL_TYPE(_v) = _t; VAL_NULL(_v) = 1; return 0; } without explicit notification that this is not-NULL value. More than, nowhere else in this function VAL_NULL(_v) not set to 0. So, if a value _v.val contained anyting but 0 at the function start, resulting value will be threated as NULL despite the fact, that _s is NOT NULL. Patch is obvious, just add VAL_NULL(_v)=0; after cited block (line 188) and everyting will be ok. At least for me it's ok for some hours :)
