Hi,
I am a tester with a VOIP comm and solutions company.
I'm a little new to the world of SIP and I'm currently working on building a
DDoS simulation for our networks. I am using this script to send multiple
register requests. I've tried to look for some place on the net that
explains this script and it's keywords but I'm not able to get anywhere. I
need to understand what each line on the script does so that I can modify it
to suit my purpose.
<?xml version ="1.0" encoding="UTF-8"?>
<scenario name="SIP DOS REGISTER">
<send>
<!CDATA[
REGISTER sip:[service]@192.168.0.10:5060 SIP/2.0
Via: SIP/2.0/[transport][local_ip]:[local_port]
From: <sip:[service]@[local_ip]:[local_port]>
To: <sip:[service]@[remote_ip]:[remote_port]>
Call-ID: [call id]
Cseq: 1 REGISTER
Contact: sip: [service]@[local_ip]:[local_port]
Max-Forwards: 70
Subject: Performance Test
Content-Type: application/sdp
Content-Length: O
]]>
</send>
</scenario>
I change the IP address here and in the command line, with various results,
in some cases no outgoing calls are even made. I'm not really able to see
what is causing these varied outputs so I need to understand this code. I've
used the trace_err log and it shed some light on this (like populating the
From, To lines and so on and so forth) but it cannot explain why sometimes
no calls are being made, because then there is no error log at all, as the
code exits gracefully.
Can anyone please help me out with this? I'd really appreciate it!
Thanks and Regards,
Rishabh Natarajan
