Hi Daniel,
Many thanks - local firewall it is my bad - I thought the fact packet sniffer can see the packet - there is no network firewall blocking the packet - but there was an IP-Tables on the host - I shutdown the ip-tables & now the registration is going through & I am also able to send calls between subscribers . The log_stderror=yes is working now I can get the error messages on the console (but for that I have to start kamailio by typing kamailio - when I start using service kamailio start I dont get any log messages).

Thanks its a step forward - I will review the config again for syslog configuration as for troubleshooting its better to have the logs dumped to a file rather then on std_error.

BTW: If you can point me to some good tutorials regarding load-balancer(dispatcher module) it will be great - 

Regards,
Faisal

Hello,

I could not spot if you checked for presence of a firewall. If you don't get any log message from kamailio, it is very likely the sip traffic is blocked -- be aware that packet sniffers grab them from the network before local firewall rules.

You can also set log_stderror=yes and the log messages should be printed to the terminal, in this way you don't care if syslog is configured or not properly, just o be sure there are log messages. Then you can get back to syslog.

Cheers,
Daniel

Change the L_WARN to L_NOTICE that makes a difference when you've different debug=x value.
and yes you are right about the  "-" in -/var/log/kamailio , it is really required to prevent kamailio from waiting on syslog to print lines and then continue.

While I didnt  restarted my syslog (as the config were there from before) - but I did check after restarting syslog  
regarding using xlog - I have 3 xlog messages in my route logic around Registration

# handle registrations
xlog("L_WARN","Code before Registrar");
route(REGISTRAR);
xlog("L_WARN","Code after Registrar");

I also have a log message at the start of the route
xlog("L_WARN","Begin Routing");

regarding the hyphen I checked removing the hyphen but based on my understanding from the link regarding enabling logging the hyphen enables asynchronous logging

Anyhow even after all these I still dont see any logs.

Hi Faisal,

You say you added to syslog.conf: local1.* -/var/log/kamailio

Is that exactly how it appears? If so, I think you need to remove the hyphen so it becomes: local1.* /var/log/kamailio

As Sammy said, don't forget to restart syslog.

Regards,

Charles

Did you restart your syslog ? Add xlog lines in yur config when you receive a REGISTER request so that it actually prints something out.

Hi  Daniel/ Sammy ,
I made the changes in config as suggested (i.e. move the define variables at the top of the file rather then in the middle)
Regarding setting debug=3 => I am setting WITH_DEBUG in the config file so based on processing of this symbol I believe debug=4 is set.#


For the log facility in the kamailio.cfg I have set the option log_facility=LOG_LOCAL1


& in my syslog.cfg (attached again) I have set the following
local1.* -/var/log/kamailio


but still I dont see any logs in this location when I start kamailio


I can see the kamailio process - (in total there are 19 processes here is the root process all other are child processes of this process) 
kamailio  3375     1  0 08:06 ?        00:00:00 /usr/local/sbin/kamailio -P /var/run/kamailio.pid -m 32 -M 4 -u kamailio -g kamailio


I can also see kamailio starting to listen on port 5060 port on the local machine on both UDP & TCP interfaces


I am using an xlite phone on windows to attempt to register - on my Kamailio VM (using UDP) I started a tcpdump to see if I am receiving the Register messages - I can see the register packets coming to the Kamailio hosts from the phone - but I dont see any responses from Kamailio.


Also as there are no logs I dont know what is going wrong.
Regards,
Faisal

Hi Faisal,


You say you've seen packets on kamailio but kamailio isn't replying !! 


1- Please verify that yuor kamailio is indeed started  [ps -ef | grep kamailio]
2- Verify if kamailio is actuallay listening on the same port as you are sending pcakets to ! [netstat -pln|grep kamailio]
3- Verify if your kamailio is using the same protocol as of your client i.e TCP or UDP or TLS etc.
4- instead of viewing the file /var/log/kamailio see /var/log/messages because you haven't mentioned local7 as Log facility in your config.
I don't see your syslog.conf  file in this mail! check that file and follow the referenced link completely.


Also see your configurations kamailio.cfg file and use define tags from second line from top onward i.e just after #!KAMAILIO.
 Try getting rid of the comment line "####### Defined Values #########" - in my experience such comment before define cause trouble with configurations.




See all these and then reply with updates.


Regards,
Sammy G.

Hello,

you can set debug=3 in kamailio config to see very verbose debug messages. If you don't get any, means the request does not reach the application layer, meaning you have a firewall in place that drops the packets from the network.

Daniel

Hi Experts,
I am a newbee with SIP-Router/Kamailio - I installed Kamailio on a CentOS 5.5 VM - following the instructions from the following link


http://kb.asipto.com/kamailio:install:3.0.x-from-git-centos5x


Kamailio is installed & I can start kamailio deamon from service kamailio start 


However I also created two subscribers - but when I try to register my SIP Phone (by setting Kamailio as the domain to register to) - I can see my sip-phone sending the Register request to Kamailio (I put a tcpdump on the kamailio machine to see sip-messages reaching the host) but I dont get any response from Kamailio - so my sip phone reaches the 408 Registeration Timeout state.


Now, I dont get any logs from Kamailio to know what is happening while my phone is sending the register request - I tried to configure logging following instructions from the following link


http://www.kamailio.org/dokuwiki/doku.php/utils:basic-syslog-configuration


But I dont get any logs in the /var/log/kamailio log file.


To assist in understanding the issue - I am attaching the syslog config , kamailio config file & the kamailio service script in the init.d folder.


My first objective will be to enable logging for kamailio & the next objective is to get the basic registration & routing between endpoints - my ultimate objective is to configure SER/Kamailio as a load-balancer for our B2BUA & Media Servers (I found the dispatcher module can help in accomplishing this) -  Can anybody help me in identifying why I am not getting any logs ?
I have already seen the wiki & have developed some understanding regarding how Kamailio is configured but am I seeking more information regarding the route language - (the state-model + reference of the functions that can be used in the route script etc.) - in this regards if I can get any documentation pointers from the user community that can help me gain a better understanding the use of Kamailio for above it will be great 


Regards,
Faisal
