Re: [SR-Users] AWS LOOP detected

It's difficult and time consuming to debug issues without seeing the config file and without seeing the packet traces (ngrep -W byline -d any -t -q -p "" port 5060). Anyway, as an admin you should understand how Kamailio works. Thus it would be a good exercise to find the problem yourself. In severl places in your config you have routing decisions (if ... {}). Identify these places, and put meaningful logging (xlog("...") ) before and after the if statement. Then make a call and watch the logfile. This will give you an understanding how Kamailio works. regards Klaus On 21.10.2013 16:04, julian arsanches wrote: > Daniel, Klaus thanks a lot for your responses i do appreciate them, just > got me a bit confuse because on the documents as what Daniel suggest to > advertise directive for listen parameter, I do if you see my config below > that i advertise it and have an alias, kamailio still sends an invite to > itself without recognizing that it came from the internal ip. > > > Is there anything else wrong that i am not putting on my advertise line ? > > thanks i really apreciate your input. > > Julian. > > /listen=udp:1.1.1.1:5060 <http://1.1.1.1:5060> advertise2.2.2.2:5060 < > http://2.2.2.2:5060> > />>/ > />>/ > />>/ alias=1.1.1.1:5060 <http://1.1.1.1:5060> <http://1.1.1.1:5060 < > http://1.1.1.1:5060/>> > />>/ alias=1.1.1.1 > />>/ alias=2.2.2.2:5060 <http://2.2.2.2:5060> <http://2.2.2.2:5060 < > http://2.2.2.2:5060/>> > />>/ alias=2.2.2.2/ > > Hello, >> >> for reference, in case kamailio is running behind nat, like on AWS, one >> should just use advertise directive for listen parameter, like:> >> >> listen=proto:privateip:port advertise publicip:port> >> >> >> See: >> >> http://www.kamailio.org/wiki/**cookbooks/4.0.x/core#listen<http://www.ka… >> >> It simplifies the config by not needing to use alias parameter, >> advertised_address/set_**addvertised_address() and >> record_route_preset().> >> >> Cheers, >> Daniel >> >> On 10/18/13 8:23 AM, Klaus Darilion wrote: >> / >> > />/ > />/ On 17.10.2013 17:31, julian arsanches wrote: > />>/ Hi all, before hand thanks for all the support received on this > channel. > />>/ > />>/ I have an issue with an installed server on a aws instance which is > />>/ giving me routing loops, my setup is simple, i have alias set for > both > />>/ ips internal and external and the loop still present when t_relay > don't > />>/ find any routes to relay it just sent it to itself with the public > ip > />>/ then the loop starts. > />>/ > />>/ can any one please advise how can i prevent that or just tell > t_relay > />>/ that if there is no more routes just respond with a cancel or stop > />>/ searching. > />/ > />/ If you call t_relay, then the message will be forwarded to $ru (or to > />/ $du if $du is set). t_relay itself does not have any logic inside. > />/ > />/ Thus, if you do not want a message to be forwarded, then you must not > />/ call t_relay. > />/ > />/ If you do not want to send a message to a certain destination, then > />/ set $ru (the domain part) to the respective destination. > />/ > />/ One issue may be the aliases.
