proper way for infinite loop in event_route for evrexec module

by Patrick Karton

Hello i would like to use the evrexec module to execute background jobs over exec module mainly because i want to be able to trigger that route manually via rpc from time to time. in the documentation its is stated we should use tasks that run forever and except using while loop i dont see another way. and i dont to want to disable max_while_loops. but if i disable it i will get error message like runaway while (1091, 9): more then 100 loops. so is there another way to do it properly ? Thanks.

Remove and Re add FROM in 200 OK sl reply

by Lewis Hutchinson

Hello All kamailio 5.5.3 KEMI Python Lab environemnt Is there a reason why this does not work? Lines 2 and 3 work but the removal of the initial From is not working on Line 1 1. KSR.hdr.remove("From") 2. KSR.hdr.append_to_reply("From: " +KSR.pv.gete("$fn") + " <"+KSR.pv.gete("$fu") + ">" + ";tag=" +KSR.pv.gete("$ft") + "--1234" + "\r\n") 3. KSR.sl.sl_send_reply(200, "OK") In a SUBSCRIBE/NOTIFY scenario I am trying to control the From Tag returned in the 200OK so I can use the same one in subsequent NOTIFY messages generated outside of Kamailio, my theory is use the From tag in the Subscribe and append it on the reply with -1234 for example (this is only in a Lab at this stage, any other options please let me know) Whenever I do this I end up with 2 From headers (see below) SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.1.67:5060;branch=z9hG4bK-f710a11a;rport=46404;received=xx.yy.xx.yy From: " testuser" sip:limeant30@sip.viazeta.com;tag=bf8745def06c7b12 To: <sip: testuser(a)sip.viazeta.com>;tag=47969b75f14e6954812863912d1cf21c.b5f3318f Call-ID: b21ba770-9b5836aa(a)192.168.1.67 CSeq: 18137 SUBSCRIBE Contact: "testuser" <sip:testuser@ xx.yy.xx.yy:46404> Expires: 3600 From: "testuser" sip:testuser@testbed.com;tag=bf8745def06c7b12--1234 Content-Length: 0 I have tried many many variations but the original From header always persists I have checked the debug logs and it says it has been removed Anyone know what I am missing? And how to get KSR.hdr.remove("From") to work. Looking in a debug log the header is removed. Lewis

Kamailio Configuration Help

by P. White

Hi All, Really sorry to bother everyone, but if possible, can I ask for a little help? I've been attempting to get Kamailio configured and working for some considerable time now (read: Years of occasional tinkering, and weeks of recent dedicated evening work) -- all without success. I have a sip trunk from sipgate, with two PSTN numbers assigned. My local network has a static external IP, with an internal private network. Currently I have Kamailio running within the intenal network along with two physical sip telephones (gigaset and an old grandstream), although I do have the option to put kamailio within a DMZ if necessary. Would anyone have a working config file that they could share please, permitting incoming and outgoing calls? With grateful thanks, Phil

Change reply code reason other than using change_reply_status

by Patrick Karton

hello is there a way to change reply code reason other than using () function. because the first parameterc of change_reply_status needs to be a constant so i can not use pseudo var for first argument of that function. so i use change_reply_status_code to change to code with a pseudo. but i would also to change the code reason.

remove_hf() does not remove the complete line

by Bernd Krueger-Knauber

Hi, I tried to remove a Via header line with: remove_hf("Via"); Original I have this 2 lines: Via: SIP/2.0/TCP xxx.xxx.xxx.xxx;branch=z9hG4bK370b.21720bb33c4f8264fde4e7994d288a57.0;i Via: SIP/2.0/TCP yyy.yyy.yyy.yyy:53967;received=yyy.yyy.yyy.yyy;rport=53967;branch=z9hG4bKPjxb0bdb2c9624076815f12937cc9e51d;alias If I insert remove_hf("Via"); in the cfg, I get: Via: SIP/2.0/TCP xxx.xxx.xxx.xxx;branch=z9hG4bK370b.21720bb33c4f8264fde4e7994d288a57.0;i ;received=yyy.yyy.yyy.yyy;rport=53967;branch=z9hG4bKPjxb0bdb2c9624076815f12937cc9e51d;alias Doesn't mattter if the command make sense or not, the result, in my opinion, is wrong. The INVITE packet has now an invalid header line. Any ideas? version: kamailio 5.6.1 (x86_64/linux) Best regards, Bernd

Kamailio has unconfined processes

by HimaBindu G

Hi, Problem Description: Customer security scan returned unconfined services on Kamailio. Unconfined processes run in unconfined domains Rationale: For unconfined processes, SELinux policy rules are applied, but policy rules exist that allow processes running in unconfined domains almost all access. Processes running in unconfined domains fall back to using DAC rules exclusively. If an unconfined process is compromised, SELinux does not prevent an attacker from gaining access to system resources and data, but of course, DAC rules are still used. SELinux is a security enhancement on top of DAC rules - it does not replace them Solution Investigate any unconfined processes found during the audit action. They may need to have an existing security context assigned to them or a policy built for them. Notes: Occasionally certain daemons such as backup or centralized management software may require running unconfined. Any such software should be carefully analyzed and documented before such an exception is made. See Also https://workbench.cisecurity.org/files/2485 For Kamailio ====== The command returned : 00 kamailio 00 kamailio 00 kamailio 00 kamailio 00 kamailio 10 kamailio 10 kamailio 10 kamailio 10 kamailio 00 kamailio 00 kamailio 00 kamailio 00 kamailio 33 kamailio 33 kamailio 33 kamailio 32 kamailio 17 kamailio 16 kamailio 33 kamailio 00 kamailio 00 kamailio 03 kamailio 05 kamailio 18 kamailio 17 kamailio 18 kamailio 18 kamailio 07 kamailio 00 sleep is any security context available to assign kamailio processes ? theses services can be run as confined services ? Please suggest us with resolution, thanks in advance. Thanks & Regards, Hima Bindu.
