I was inspired by Daniels ClueCon 2013 talk and have decide to try to add simple rate limiting using a HTable. $var(srcgroup) is an id that identifies the invites source/ I wish to limit invites from a given source. $var(rateHashMin) was added just to allow simple monitoring. I query the table via XML-RPC to get an idea of current load. I think it would be better to add it to a seperate table and then I could increase the exprires time to capture more of the course grain points. I am interested in any comments. ---------------------- modparam("htable", "htable", "htable_source_group_rates=>size=8;dbtable=htable_source_group_rates;initval=0;autoexpire=300;") modparam("htable", "htable", "htable_source_group_limits=>size=8;dbtable=htable_source_group_limits;initval=500;") ---------------------- ---------------------- route[SOURCE_GROUP_LIMIT] { if (is_method("INVITE")){ $var(rateHashSec) = (str)$var(srcgroup)+":sec:"+$timef(%Y/%m/%d_%H_%M_%S); $var(rateHashMin) = (str)$var(srcgroup)+":min:"+$timef(%Y/%m/%d_%H_%M_00); $sht(htable_source_group_rates=>$var(rateHashSec)) = $sht(htable_source_group_rates=>$var(rateHashSec)) + 1; $sht(htable_source_group_rates=>$var(rateHashMin)) = $sht(htable_source_group_rates=>$var(rateHashMin)) + 1; if($sht(htable_source_group_rates=>$var(rateHashSec)) > $sht(htable_source_group_limits=>$var(srcgroup))) { sl_send_reply("503", "$si over source Limit of $sht(htable_source_group_rates=>$var(rateHashSec)) / $sht(htable_source_group_limits=>$var(srcgroup)"); exit; } } } ---------------------- Thanks Gareth

Error in Kamailio_ims v 4.0.3

by Sai Krishna Kota

Hello Carsten, Yha I have not included 'xmlrpc' for compilation. Can you please list all the required modules to be compiled with the ims modules so that I can know more about kamailio-ims. Thank you, Kota Sai Krishna

Cross-Compilation Problems for mips (gcc 3.4.2)

by Tirant Lo Blanc

Hi, I've been exploring the possibility to port Kamailio 3.3 (SER) to some MIPS boards. I didn't have any problem with the first one, with a GCC 4.3.4 toolchain. But on my second board (gcc 3.4.2) I am having problems when compiling. Are there any requirements for gcc/binutils/kernel versions? This is the log I am getting: CC (mipsel-linux-uclibc-gcc) [ser]sip_msg_clone.o In file included from atomic_ops.h:181, from sip_msg_clone.c:43: atomic/atomic_unknown.h:59:2: warning: #warning no

tls nat

by hiro

After many failures because of broken libraries I managed to decrypt my problematic TLS sessions providing the private key of kamailio to wireshark. With TLS+SRTP enabled my nokia phones send session progress and pracks with rtp port. This breaks NAT/rtpproxy in kamailio, which replaces the rtpproxy port in session progress, but then forgets about it for the 200 OK. Attached is a tree overview and the conversations of each phone with kamailio. hiro

RPC command dlg.list (for large amounts of dialogs)

by Alex Balashov

Hello, I am having trouble getting a large list of dialogs (800+) out of Kamailio using the dlg.list binrpc command. I posted a while back that the list of dialog data was coming back truncated, and was told to increase: modparam("ctl", "binrpc_max_body_size", ...) modparam("ctl", "binrpc_struct_max_body_size", ...) I did that, increasing the buffers to 20 MB. Then, when I ran sercmd -s unixs:/tmp/kamailio_ctl dlg.list I got: ERROR: reply too big which clearly seemed to be on the client side now. So, I looked in the sources for sercmd (now sercmd), in sip-router/utils/sercmd/sercmd.c, and found this: if ((ret=get_reply(s, reply_buf, MAX_REPLY_SIZE, cookie, &in_pkt, &msg_body))<0){ switch(ret){ case -1: goto error_read; case -2: goto error_parse; case -3: goto error_cookie; case -4: goto error_toobig; So, I adjusted: #define MAX_REPLY_SIZE to several megabytes as well, and tried the same with MAX_BODY_SIZE too. Now, when I run the dlg.list command, it just hangs and never returns anything. It was stuck there for well over 20 minutes. An 'strace' on sercmd reveals that it receives what appears to be the full listing, but keeps wanting to read() more. I don't have the exact output handy at the moment, but it looked like this: socket(PF_FILE, SOCK_STREAM, 0) = 3 connect(3, {sa_family=AF_FILE, path="/tmp/kamailio_ctl"}, 110) = 0 writev(3, [{"\241\3\v%s\230\4", 7}, {"\221\tdlg.list\0", 11}], 2) = 18 read(3, "\241\27\16\257%s\230\4\221Hhash:551:9521 state:4 "..., 786432) = 340000 read(3, [just hangs here] Now, I would have assumed that perhaps there is more to read and the output is not returning due to some endless locking of the dialog profile table, which is constantly changing. However, that cannot be the case because kamctl fifo dlg_list works fine for any amount of dialogs, and always returns all the data near-instantly! Any assistance is much appreciated! -- Alex [1] I don't have the output handy at the moment, but it was a read() value: -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/

Query about Link Redundancy for Kamalio Server

by Owais ul Haq

Hello, Here is a query about kamailio deployment. If some one can please help in this regard.We have deployed a Kamailio server.. But due to some un-aviodable issues, our internet connection is unreliable. So to counter this we have got two internet connection with static IP's. Can some one advice some mechanism so that our Kamailio server automatically switches itself from one IP to other one in case of internet connection failure. How can this be achieved ? Any help will be appreciated. Thanks.
