[Serusers] Few Questions
by Jai Rangi 10 Mar '08

10 Mar '08

Hello, I see some of these errors and warnings in my log file on SER. WARNING: warning skipped -- too big ERROR: t_reply: cannot send a t_reply to a message for which no T-state has been established ERROR: warning_builder: buffer size exceeded How can I get rid of these. Also I had a question on children=4 I know this has been asked before and has been answered. This is what I found online. *"children=4" mean that there will be 4 UDP, 4 TCP and 4 loopback **listenters on your SER, when you start it (you can check with "serctl ps**s" to verify). * Question is does this have any affect on the number of simultaneous calls or sip users etc. Say I want to make sure my system works without any problem for 20K user and 5000 simultaneous calls. What can be pros and cons if I set children to 10, 50 or 100. I will appreciate if anyone can educate me little more on this. Thank you, -Jai

[OpenSER-Users] isflagset from other peer ?
by David Loh 10 Mar '08

10 Mar '08

Hi All, I'm facing a situation for P2P call where it need to determine both caller and callee network type, except for both parties having direct (internet) connection (on Public IP), the rest of combinations will implement force_rtp_proxy. (the 4 combinations are: NAT-> NAT, NAT -> Public IP, Public IP -> NAT, Public IP -> Public IP). Wondering if I can use isflagset or fetch flag from remote peer (callee) ? or is there any function that allow this to be happen ? Thanks, David Loh

[OpenSER-Users] HELP - OpenSER 1.3 not parallel forking?
by Daryl Sanders 09 Mar '08

09 Mar '08

Hi All, I am testing parallel forking so I can setup ring groups, but it seem I cannot get OpenSER 1.3 to parallel fork contacts of the same q-value. It always seem to use the first record found in MySQL, and ignores all others. I have tried adding append_branch after lookup("location") , but that did not seem to help. I've also done ethereal captures and confirmed that it is only sending an INVITE to the first contact in MySQL (I've tried db_mode 3 and 1). I'm know I'm missing something, but not sure what. I've included relevant portions of my test config below. Any help would be greatly appreciated. Regards, Daryl route { # ----------------------------------------------------------------- # Sanity Check, NAT Check & General Routing # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops"); exit; } if (msg:len > max_len) { sl_send_reply("513", "Message Overflow"); exit; } if (nat_uac_test("19")) { setbflag(6); xlog("L_INFO", "NAT CLIENT - M=$rm RURI=$ru F=$fu T=$tu IP=$si\n"); } if (method=="INVITE" || method=="ACK" || method=="BYE") { setflag(1); } if (method!="REGISTER") { record_route(); } if (loose_route()) { xlog("L_INFO", "LOOSE ROUTING - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); if (!t_relay()) { sl_reply_error(); } exit; } if (method=="REGISTER") { route(2); exit; } else if (method=="INVITE") { route(3); exit; } route(1); exit; } route[1] { # ----------------------------------------------------------------- # Default Message Handler # ----------------------------------------------------------------- if (uri=~"[@:](192\.168\.|10\.|172\.(1[6-9]|2[0-9]|3[0-1])\.)" && !search("^Route:")){ sl_send_reply("479", "We don't forward to private IP addresses"); exit; } t_on_reply("1"); t_on_failure("1"); if (!t_relay()) { sl_reply_error(); } exit; } route[2] { # ----------------------------------------------------------------- # REGISTER Message Handler # ----------------------------------------------------------------- sl_send_reply("100", "Trying"); if (!www_authorize("","subscriber")) { www_challenge("","0"); exit; } consume_credentials(); if (!save("location")) { sl_reply_error(); } xlog("L_INFO", "REGISTER - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); } route[3] { # ----------------------------------------------------------------- # INVITE Message Handler # ----------------------------------------------------------------- xlog("L_INFO", "INVITE - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n"); # Trusted IP if (src_ip==xxx.xxx.xxx.xxx) { strip(2); xlog("L_INFO", "FROM PSTN - M=$rm RURI=$ru F=$fu T=$tu IP=$si\n"); } else { if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); exit; } consume_credentials(); } if (lookup("location")) { xlog( "L_NOTICE", "USER FOUND - M=$rm RURI=$ru F=$fu T=$tu IP=$si\n"); } else { xlog( "L_NOTICE", "USER NOT FOUND! - M=$rm RURI=$ru F=$fu T=$tu IP=$si\n"); } if (isbflagset(6) || !lookup("location")) { xlog( "L_NOTICE", "RELAYING MEDIA - M=$rm RURI=$ru F=$fu T=$tu IP=$si\n"); route(4); exit; } route(1); exit; } route[4] { # ----------------------------------------------------------------- # PSTN Handler # ----------------------------------------------------------------- force_send_socket(xxx.xxx.xxx.xxx:5060); xlog("L_NOTICE", "FORWARDING TO PSTN\n" ); ds_select_domain("1","0"); route(1); exit; }

by jh＠tutpro.com 09 Mar '08

a question: is it possible to specify destination uri ($du) per branch, i.e., if i set $du a value in branch route, does it apply only to that branch when t_relay is called? -- juha

[OpenSER-Users] append_branch and $T_branch_idx behavior
by Ovidiu Sas 07 Mar '08

07 Mar '08

Hello, I was playing wit append_branch and I run into this issue. Here's a snippet of the code: route[2] { $var(uri) = $ru; append_branch(); $ru = $var(uri) + ";transport=udp"; t_on_branch("2"); } branch_route[2] { xlog("L_INFO", "entering branch[$T_branch_idx] for $ru\n"); if ($T_branch_idx == 1) { xlog("L_INFO", "dropping branch[$T_branch_idx]\n"); drop(); } } In the logs, I got: entering branch[1] for sip:<user>@<IP>;transport=udp dropping branch[1] entering branch[1] for sip:<user>@<IP> dropping branch[1] ERROR:tm:t_forward_nonack: failure to add branches Is this the expected result? It seems that we do have two branches, since we enter twice in the branch_route, but the $T_branch_idx doesn't seem to be updated. Or, it is supposed to be updated? Any hints would be appreciated. BTW: this is with 1.3 code base. Regards, Ovidiu Sas

Re: [OpenSER-Users] issue - remote sip client must re-register after failover in Openser Registrar HA config
by Naija Man 07 Mar '08

07 Mar '08

Thanks Patrick, I have re-configured a common database for the servers and I am still having the same issues. Can this be an issue with PAT at the Load balancer after failover since the INVITE is coming from openser_2 and going to the same IP:port associated with openser_1. I am also open to trying other methods to achieve OpenSER registrar HA if any available. Thanks.

[OpenSER-Users] ERROR:core:main: bad user name/uid number: -u openser
by bsb093 07 Mar '08

07 Mar '08

Hi all, I am still trying to run OpenSER. Now I see the following error: ERROR:core:main: bad user name/uid number: -u openser I am trying to install version 1.3 with MySQL. I have succeeded to create the db but when trying to run OpenSER I still have this error. I have found in the forum that maybe I don't have openser user in /etc/passwd and that is true but I can't figure how to create that user. Any suggestions? Thanks in advance, Shine -- View this message in context: http://www.nabble.com/ERROR%3Acore%3Amain%3A-bad-user-name-uid-number%3A--u… Sent from the OpenSER Users Mailing List mailing list archive at Nabble.com.
