Hello,
what version of kamailio are you using and what http version is curl
using? Can you paste here the http request taken with ngrep from the
network?
Cheers,
Daniel

Hi Daniel,
There's no other traffic than the HTTP requests.
This comment in src/core/parser/parse_fline.c 99 - 113, caugh my
attention:
} else if (http_reply_parse != 0 &&
(*tmp=='H' || *tmp=='h') &&
/* 'HTTP/1.' */
strncasecmp( tmp+1, HTTP_VERSION+1, HTTP_VERSION_LEN-1)==0 &&
/* [0|1] */
((*(tmp+HTTP_VERSION_LEN)=='0') || (*(tmp+HTTP_VERSION_LEN)=='1'))
&&
(*(tmp+HTTP_VERSION_LEN+1)==' ') ){
*/* ugly hack to be able to route http replies
* Note: - the http reply must have a via
* - the message is marked as SIP_REPLY (ugly)*
*/
fl->type=SIP_REPLY;
fl->flags|=FLINE_FLAG_PROTO_HTTP;
fl->u.reply.version.len=HTTP_VERSION_LEN+1 /*include last digit*/;
tmp=buffer+HTTP_VERSION_LEN+1 /* last digit */;
and later in error1:
error1:
fl->type=SIP_INVALID;
LOG((core, core_cfg, corelog), "parse_first_line: bad message (offset:
%d)\n", offset);
/* skip line */
nl=eat_line(buffer,len);
return nl;
So that log line can be conditional if FLINE_FLAG_PROTO_HTTP is not
part of fl->flags.
I just don't know where the "[466B blob data]" is getting printed

Hello,
as I said, watch the traffic on port 8000 with ngrep or some other
network sniffer to see what data comes there. You can also start
kamailio with debug=3 in config, more debug logs should be printed
to syslog to get the context of what is processed at that time.
Cheers,
Daniel

Hi Daniel,
Thanks for your feedback.
I have a dedicated listen directive for JSONRPC
listen = 127.0.0.1:8000 <http://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

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
