Hi Daniel,

Thanks for your feedback.

I have a dedicated listen directive for JSONRPC

listen = 127.0.0.1:8000

and then an event_route for it:

event_route[xhttp:request] {
if ($Rp != 8000) {
xhttp_reply("403", "Forbidden", "text/html", "<html><body>Forbidden</body></html>");
exit;
}
if ($hu =~ "^/RPC") {
jsonrpc_dispatch();
} else {
xhttp_reply("200", "OK", "text/html", "<html><body>Wrong URL $hu</body></html>");
}
return;
}

So, I'm already doing HTTP traffic only in port 8000.

The interesting part is that if I use kamcmd pl.list pipe_INVITE, only the first log line is printed. Using curl, I see the other 2 logs all the time.

Thank you

Hello,

can you want the traffic on port 8000 and see if there is no "unexpected" traffic there? There should be no error message for parsing the first line of an HTTP request.

The error message related the missing pipe can be made debug.

Cheers,
Daniel

Hi all,

I'm using pipelimit with the "clean_unused" option to get rid of pipes that are not used for quite some time. At the same time we are monitoring pipelimit with a jsonrpc call similar to:

# curl --header 'Content-Type: application/json' --data-binary '{"id": 1, "jsonrpc": "2.0", "method": "pl.list", "params": ["pipe_INVITE"]' http://127.0.0.1:8000/RPC

Reply:

{
"jsonrpc": "2.0",
"error": {
"code": 400,
"message": "Unknown pipe id pipe_INVITE"
},
"id": 1

}

The above reply is valid because the pipe_INVITE was not loaded yet, but the request makes kamailio to log the following log messages:

Jan 20 11:21:48 proxy1 kamailio[24474]: ERROR: pipelimit [pl_ht.c:519]: rpc_pl_list(): no pipe: pipe_INVITE
Jan 20 11:21:48 proxy1 kamailio[24474]: ERROR: <core> [core/parser/parse_fline.c:262]: parse_first_line(): parse_first_line: bad message (offset: 20)
Jan 20 11:21:48 proxy1 kamailio[24474]: [466B blob data]

Since the monitoring system does periodic requests, those log lines get a bit annoying and fill the log with ERROR messages that aren't really errors.

IMHO the first log line should be converted to DEBUG instead of ERROR, but I have some doubts about the one from parse_fline.c:262. parse_first_line() is used to process both SIP and HTTP. It makes sense to log ERROR if SIP but not in the case of HTTP...

Regarding the "[466B blob data]" I really don't know from where it's coming from.

I can submit a PR, but I would like to have first some feedback from you.

Thank you,

Nuno
