Re: [Serusers] Starting SER : PID file exists(/var/run/ser.pid)already running?
by Aisling O'Driscoll 12 Apr '05

12 Apr '05

Ok I still have this error. However I have manageed to start SER another way. I did "find / -name ser_mysql.sh" beacuse I thought the problem stemmed from my database. I then deleted all the ser_mysql.sh scripts that werent supposed to exists out the /opt/ser directories. i did a manual drop the database and then started the mysql script as /opt/ser/sbin/ser_mysql.sh create. This worked and the tables are updated e.g. verion is now table_version. I still get an error when I start SER as /opt/ser/sbin/serctl start (PID already exists). However the server works when i start it as ser -d -E. ---- Original Message ---- From: ashling.odriscoll(a)cit.ie To: ashling.odriscoll(a)cit.ie, greger(a)teigre.com, ashling.odriscoll(a)cit.ie Subject: Re: [Serusers] Starting SER : PID file exists(/var/run/ser.pid)already running?

RE: [Serusers] Load Balancing via UltraMonkey/ldirectord
by Matt Schulte 12 Apr '05

12 Apr '05

Yah I noticed the other post after I posted mine, I don't see how it would easily be possible to address the sticky issue. It would require making a SIP aware proxy of sorts, which is a bit out of my abilities. Has anyone been able to address this issue? Of course a layer7 switch would do wonders and eliminate the need for all this, but who has that money laying around :D I've done a little research (google) and noticed people mentioning it when talking about LVS, one guy said he was going to write a module but posted nothing more. That would be pretty slick. Matt -----Original Message----- From: Greger V.

Re: [Serusers] still no help - usrloc synchronization

Pretty good news, Paul. I've only tested IP tunneling. It worked for me. The problem I described was born in my thoughts. I've also read some complaints from SIP-LVS users. The only configuration where Call-Id stickness does not necessary is LVS-NAT. Unfortunately, NAT becomes bottleneck very fast. Java Rockx <javarockx(a)gmail.com> wrote: Tina, I wish I had more information on that, but that LVS stuff is a black art to me. One of our engineers whipped up an LVS configuration that seems quite happy with the Call-ID "stickness" you described. All I can say right now is that it is apparently possible to do this with 100% open source. (i'm keeping my fingers crossed) :-) Regards, Paul On Apr 10, 2005 11:03 PM, Tina <kramarv(a)yahoo.com> wrote:Paul, thanks a lot, it helps a lot.

KRs, Tina Java Rockx <javarockx(a)gmail.com> wrote: Tina, I really don't know how the LVS server is configured because our network guy that we acquired from RedHat set all that stuff up.

These include SER, MySQL, Apache, configuration management, monitoring, RTP proxies, etc. MySQL is active-active so we have two-way replication. We only have 2 MySQL servers. And this is all we plan on ever having as MySQL is more than capable of handling anything ser can throw at it (given the right hardware). Each ser server is 100% oblivious to other SER servers except for when handling REGISTER messages. Here is basically the ser.cfg for each SER server: listen=10.3.0.221 # this will be 10.3.0.222 on the peer sip proxy modparam("usrloc", "db_mode", 1) # write-through route { if (method=="REGISTER") { if (src_ip==10.3.0.221) { # ip of peer ser proxy save_memory("location"); break; } else { save("location"); t_replicate("10.3.0.222"); break; }; }; } We have identifed a deficiency in the usrloc module urecord.c file whereby when using write-though mode the save_memory() function still attempt to update MySQL. This is a very bad thing because it causes a primary key violation on the location table. Yesterday I posted a patch to serdev to fix this, but today we identified another case where save_memory() tried to insert in to the location table. I'll post a revised patch to serdev as soon as I get a chance. So here is what happens. Assume I have two sip routers and two MySQL servers as: sip-01 is 10.3.0.221 sip-02 is 10.3.0.222 db-01 is 10.2.0.21 db-02 is 10.2.0.22 Now let's just assume that sip-01 is connected to db-01 and sip-02 is connected to db-02. When a SIP UA connects to a sip router (via LVS), assume sip-01 in this example and REGISTERs, sip-01 will call save("location") which updates/inserts to the location table. sip-01 then calls t_replicate to sip-02. sip-02 recieves the REGISTER message and calls save_memory("location") to update its in-memory cache only. It should never hit db-02. Now db-01 eventually (within a second or two) replicates to db-02 and now sip-02 is good to go, even in the event of a restart. Our difficulties mostly surrounded the fact that ser was inserting the physical IP of eth0 on the server as the top VIA rather than the VIP as required. We solved this by using record_route_preset() and passing the VIP as the IP. We also had to bring up a dummy interface in order to get ser to honor the VIP. Hope this helps. Regards, Paul On Apr 8, 2005 7:19 PM, Tina <kramarv(a)yahoo.com> wrote: Paul, we are using LVS as well. It creates template connection according to source Ip (e.g. UAC) and forwards to one of the tunneled IP. I tested this a couple of weeks ago, ser was happy and inserted VIP into via header, the only issue is to route the calls into right server. I agree, there is no such thing as SIP-level clustering. However, how would you solve location problem by DB replication - 1) usrloc does not update from DB....2) even though, I am afraid it can become bottleneck and lock down users ...

I believe the load balancer can be in front and transparantly translate addresses in the SIP messages: User agent always sees a.b.c.d | Load balancer with public IP a.b.c.d | | ser1 (10.0.0.2) ser2 (10.0.0.3) Paul: You have a similar load-balancing solution, right? Do you use a commerical load balancer that you can reveal the name of? :-) Our platform is 100% open source. Our load balancer is LVS. I have no idea how it actually works. One if our engineers from RedHat set all that networking stuff up and it's way beyond me. The load balancer need to understand SIP (sort of) and use something (ex. IP address of user agent) to select SER server to send to and rewrite incoming to 10.0.0.2 and 10.0.0.3 respectively and outgoing to a.b.c.d. ser1 and ser2 will happily believe they are alone and communicate directly with user agent using their own private addresses. Both should know about all users (usrloc). Paul just recently posted a small patch for a setup where they use two-way replication between two That small patch will need a slight revision. We discovered through further testing that that patch only fixed attempts to INSERT into the location table. We didn't cover the UPDATE route, unfortunately. I believe Andrew has that patch done and is testing it. So I'll post it to serdev as soon as we know it works - possibly later today. mysql servers and where each SER instance will save all REGISTERs it receives from user agents, but only save to memory those replicated from the other SER peer. Klaus pointed out that the same can be done by not doing mysql replication, but have one DB for each SER and just use t_replicate() and save_noreply() (for two servers, for more than two you need to use forward_tcp()). I have heard complaints that this approach will generate too much network traffic. Also, t_replicate() does not guarantee delivery of the replication (forward_tcp is better, but not fool proof). So, the "best" solution would probably be to hope that Paul's I fully agree. Replication at the sip proxy level, IMHO, is not a good idea. From a purist point of view, replication is not a function of a SIP router - nor should it be. It is a function of the database and we believe that the MySQL replication is a better approach from a speed and reliabilty point of view - not to mention that it simplifies the tasks of the sip router. recent TCP/UDP patch for network access to FIFO commands get included in the CVS. Then, a new replication module should use XMLRPC or whatever protocol the patch is using to forward (in a guaranteed mode) the usrloc information, which then would be injected directly into SER's memory, just like save() would, and of course in whatever db_mode you would like. The replicaton module would have to keep a queue (of course, flushed to a DB or something) in case of network problems, so that the replication would be done (sooner or later) regardless of problems. Of course, this is a major undertaking, so for most replication scenarioes, I would think the forward_tcp() + save_noreply() would work just fine. g-) > "Greger V.

Yes, but, if UA is behind symmetric NAT, I would not configure STUN to it. I'd just led mediaproxy solve the problem.

[Serusers] Tags, forwarding, redirects, and picky UACs
by Alistair Cunningham 12 Apr '05

12 Apr '05

I'm trying to implement forwarding to voicemail with a UAC that's picky about the tags in the To: headers it receives. First, I tried the following: failure_route [1] { rewritehostport("192.168.1.1:5060"); append_branch(); t_relay(); } This failed because the UAC received a "180 Ringing" from the ringing Grandstream phone via ser that contained a To: tag. After the timeout, it received another 180 from Asterisk (the voicemail system) with a different tag. Since it doesn't support forked INVITES, it dropped the call. Then I tried: failure_route [1] { rewritehostport("192.168.1.1:5060"); t_reply( "302", "Moved Temporarily" ); } This time it receives the 180 from the phone as before. Then it receives the 302. Alas, SER has ignored the tag from the phone, and created a new one of it's own, so the UAC again drops the call. Does anyone know of a way round this? Can SER be persuaded to use a tag it has already received? Can I strip the tag from the To: header in one or both of the responses? I'm willing to get my hands dirty with the SER source code if necessary. -- Alistair Cunningham, Integrics Ltd, +44 (0)7870 699 479 http://integrics.com/

[Serusers] No response in serctl add with password heslo
by Che Sosa 12 Apr '05

I tried adding subscribers using serctl: serctl add che che123 che@localhost It prompts for a MySql password. When I use "heslo", I get NO response. I tried changing the password of admin using: serctl passwrd admin heslo123. This command works with password heslo. What possibly went wrong?

Dear all, Following my previous email below, I am still facing the same problem without success of any solution. In this respect, I would very much appreciate whether someone who has come across the same problem in the past and possibly solved it, could at least possible tell me if it was a Cisco IOS issue or a ser configuration issue. Many thanks in advanced.

Next message: [cisco-voip] Domain name Change Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] --------------------------------- Hi,I've a Cisco 5300 running firmware image c5300-js-mz.122-15.T12.bin that interacts with SipExpressRouter (SER) from iptel.org.Following scenario: a caller from ISDN calls a number which is routed thru the C5300 to SER, where it is forwarded back to ISDN via the C5300 again. In this, and only in this scenario, the caller doesn't hear any early media (no ringback, no announcements etc).It works like charm when I for example call from a Cisco ATA to ISDN via C5300 and vice versa.When I configure "voice call send-alert" at the C5300, the PROGRESS is converted to ALERT and I hear a ringback tone, but other early media like announcements are also overwritten by a ringback tone.I've also tried "progress_ind setup enable 3", 8 for alert and 8 for proceed, without any success.I've alread studied (hopefully) all available Cisco documentation (voice commands for Firmware 12.2-T, the "Interworking Signaling Enhancements for H.323 and SIP VoIP", the "PSTN Callers not Hearing any Ring Back When they Call IP Phones", "Troubleshooting No Ringback Tone on ISDN-VoIP (H.323) Calls" and so on).Any hints?Regards,AndyPS: I've attached the Q931-debug and here are also the relevant parts of the C5300 configuration:voice call send-alert!voice-port 0:D input gain 2 echo-cancel coverage 32 echo-cancel suppressor timeouts interdigit 3!dial-peer voice 9 pots application session destination-pattern 0. no digit-strip direct-inward-dial port 0:D!dial-peer voice 99 voip destination-pattern [1-9]...T translate-outgoing calling 5 translate-outgoing called 1 voice-class codec 1 session protocol sipv2 session target dns:my.sipserver.com dtmf-relay h245-signal no call fallback no vad!gateway timer receive-rtcp 5!sip-ua retry invite 2 retry response 2 retry bye 2 retry cancel 2-------------- next part --------------A non-text attachment was scrubbed...Name: isndlog_sig.txtType: plain/textSize: 4876 bytesDesc: not availableUrl : https://puck.nether.net/pipermail/cisco-voip/attachments/20040512/48048430/… --------------------------------- Previous message: [cisco-voip] CCM 3.2 and call Parks..
