Hi,

Looking for some advice running the debugger and setting breakpoints in Kamailio modules such as the SCSCF.

Example: We were trying to watch the authenticate() function:

714 int authenticate(struct sip_msg* msg, char* _realm, char* str2, int is_proxy_auth) {

Our Kamailio 5.2.2 code was compiled and linked from source with the -g option already enabled by default.

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:

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.

Question:

What pid will we use to catch the authenticate() called during an initial registration from a boghe client?

Anything special we may be missing, gdb related or Kamailio settings?

kamcmd -s /run/kamailio_scscf/kamailio_ctl

kamcmd 1.5

Any advice appreciated.
