<p class="MsoNormal">Hi,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Looking for some advice running the debugger and setting breakpoints in Kamailio modules such as the SCSCF.
<u></u><u></u></p>
<p class="MsoNormal">Example: We were trying to watch the authenticate() function:<u></u><u></u></p>
<p class="MsoNormal">714 int authenticate(struct sip_msg* msg, char* _realm, char* str2, int is_proxy_auth) {<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Our Kamailio 5.2.2 code was compiled and linked from source with the -g option already enabled by default.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">We also dropped our Workers to 1 from 16 in the scscf.xml file for the SCSCF to limit the thread count and get the following list of threads below:<u></u><u></u></p>
<p class="MsoNormal">We tried the first cdp threads: 8462, 8463, and 8464 and while we could set a break point at line 714 for the authenticate() function, it didn’t actually break there at all.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Question: <u></u><u></u></p>
<p class="MsoNormal" style="text-indent:0.5in">What pid will we use to catch the authenticate() called during an initial registration from a boghe client?<u></u><u></u></p>
<p class="MsoNormal" style="text-indent:0.5in">Anything special we may be missing, gdb related or Kamailio settings?<u></u><u></u></p>
