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

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#idp16998...

Thanks, I'll have a look at it. Looks much easier than setting up Ssh connections programmatically.

What am I doing wrong here?

# ----- xhttp params ------ modparam("xhttp", "url_match", "null")

# ----- xhttp_rpc params ------ modparam("xhttp_rpc", "xhttp_rpc_root", "http_rpc")

####### Routing Logic ########

event_route[xhttp:request] { xlog("L_INFO", "************************************** RECEIVED NEW HTTP REQUEST: $hu *********************************"); 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.

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.

####### Routing Logic ########

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#idp16998...

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.****

Using 4.0.2. But I think I found the problem.

I've already sent the mail explaining it, but it's waiting approval because it's too big.

We haven't loaded any db engines except for db_unixodbc, which is not part of this list.

Hi,

It would appear then that unixodbc support is not currently available in kamctl directly, so you are in fact limited to MI command ds_reload.

For your case, you could try loading MI_RPC module which exports an additional RPC command: mi.

Then issue your command like:

kamcmd mi ds_reload

If that works for you, then the same command passed via xhttp_rpc should also work.

Cheers,

Charles

New subject: Communicate with Kamailio through external application

Hello,

I've loaded the mi_rpc module and configured the rpc_url param, but I can't issue the kamcmd mi ds_reload command from the web interface. Executing the command in the console works just fine, but only when I leave the binrpc modparam as default. I'm probably doing something wrong.

# ----- xhttp params ------ modparam("xhttp", "url_match", "^/http_rpc")

# ----- xhttp_rpc params ------ modparam("xhttp_rpc", "xhttp_rpc_root", "http_rpc")

# ----- mi_rpc params ------ modparam("mi_rpc","rpc_url","tcp:192.168.1.10:2046")

The mi_rpc documentation says: "rpc_url". This parameter is required if you need to run RPC commands from the MI. It must match a URL to which the RPC is bound. Is this referring to the binrpc modparam?

Any tips?

Hi,

You are not doing anything wrong - on very quick inspection of the code it appears you won't be able to issue the command via the xhttp_rpc module.

So other than changing DB (although I assume you are using MSSQL for a very specific reason), it looks like you may have to stick to the original remote SSH connection idea. Until someone has time and inclination to add the unixodbc support that is.

Unless anyone else can offer some alternative...

Charles

Is this referring to the binrpc modparam?****

Any tips?****

Hi,****

It would appear then that unixodbc support is not currently available in kamctl directly, so you are in fact limited to MI command ds_reload.****

For your case, you could try loading MI_RPC module which exports an additional RPC command: mi.****

Then issue your command like:****

kamcmd mi ds_reload****

If that works for you, then the same command passed via xhttp_rpc should also work.****

Hello,

I'll go for the remote Ssh idea for now and keep an eye on future releases. Thank you for your help!

Hi,

You are not doing anything wrong - on very quick inspection of the code it appears you won't be able to issue the command via the xhttp_rpc module.

Unless anyone else can offer some alternative...

Regards,

Charles

I think I found the problem.

Open /usr/src/kamailio-4.0.2/utils/kamctl/kamctl. Go to line 1540 (Dispatcher) This executes the require_dbengine function.

The db_unixodbc isn't part of this dbengine list. So when no other db engine is loaded(as in our case) you can't execute the kamctl dispatcher reload command.

require_dbengine() { if [ $DBENGINELOADED -eq 0 ] ; then merr "This command requires a database engine - none was loaded" exit -1 fi }

### DBENGINE # DBENGINELOADED=0 case $DBENGINE in MYSQL|mysql|MySQL) if [ -f "$MYLIBDIR/kamctl.mysql" ]; then .

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?

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)

When executing the dispatcher.reload command I'm receiving the following error: 8(10201) ERROR: dispatcher [dispatch.c:725]: ds_load_db(): invalid DB handler

root@proxy01:~# kamctl dispatcher reload ERROR: This command requires a database engine - none was loaded

My Dispatcher table is loaded using db_unixodbc, because we are using MSSQL.

# ----- db_unixodbc params ----- modparam("db_unixodbc", "ping_interval", 600) modparam("db_unixodbc", "auto_reconnect", 0) modparam("db_unixodbc", "use_escape_common", 1)

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.

####### Routing Logic ########

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#idp16998...

Charles
