Hello,

I didn’t, but I just loaded it, but I haven’t set any modparams yet.

Now it’s giving me more error output:

Hi,

Regarding kamcmd failure - do you have the ctl module loaded?

Regards,

Hello,

The kamctl fifo ds_reload command works when I use it in putty.

The kamcmd dispatcher.reload command does NOT work.

Hi,

I think you are mixing up the MI and RPC commands.

Try:

kamctl fifo ds_reload

kamcmd dispatcher.reload

(note the difference between kamctl and kamcmd)

The Dispatcher table is loaded just fine on startup of Kamailio.

kamctl fifo ds_list shows the table data.

Right! Totally forgot about that.

Thanks, Kamailio is now receiving the requests!

Hi,

Have you added the appropriate listen= and/or port= directive to your config?

http://www.kamailio.org/wiki/cookbooks/4.0.x/core#listen

http://www.kamailio.org/wiki/cookbooks/4.0.x/core#port

Also make sure you have not disabled TCP.

Regards,

Charles

xhttp_reply("200", "OK", "text/html","<html><body>OK – Request Received</body></html>");

}

It seems like Kamailio isn’t receiving the HTTP requests.

Im doing a simple HTTP GET (http://192.168.1.10/http_rpc) using my browser to see if it hits the event_route.

From what I understand, the RCP command is in the url of the HTTP request, and is extracted using string transformations.

I’ve never done anything with RPC directly, so maybe I’m just wrong.

Also, I don’t see Kamailio binding to the HTTP port.

The xhttp_rpc_root param only allows alphanumeric values, so I can’t specify a full URL.

Thanks, I’ll have a look at it.

Looks much easier than setting up Ssh connections programmatically.

Hi,

Take a look at http://www.kamailio.org/docs/modules/stable/modules/xhttp_rpc.html, which allows you to receive/handle RPC commands over HTTP.

Then use the appropriate RPC command in dispatcher module to reload table: http://www.kamailio.org/docs/modules/stable/modules/dispatcher.html#idp16998512

Hello,

When adding rows to the dispatcher table, the table in memory needs to be refreshed. Since we have multiple Kamailio instances running on different machines, I’d like to automate the process of reloading the table.

Is there an easy way of doing this with an already existing module, which provides easy connectivity from the outside?

Or do I need to write an application which basically sets up a SSH socket connection with the machine and sends the command “kamctl dispatcher reload” then exit? Not that hard either, but there might be a finer solution available.

Regards,

Grant
