[Serusers] extravagant behavior, nat problem ?
by Alessio Focardi 17 Feb '04

17 Feb '04

Dear friends, anyone has some experience of cisco PIX configuration with sip, I suspect a nat problem, but i'm not sure .... My situation: Ser/Asterisk server on a real ip address, no firewall, open ip Grandtream phone, real ip address Xlite client, natted by pix with a internal/external direct conduit, allow any rule for inside/outside connections Tests made: direct call Grandstrem ---> ser ---> Xlite = ok Xlite ---> ser ---> Grandstream = ok ok now to the problem, I know this is a long explanation, but I badly need help, this looks to complex for me ! :) Grandstream calls 10, ser has this rule if (uri=~"sip:10+@") { rewritehostport("host.domain:5090"); t_relay_to_udp("host.domain", "5090"); break; }; call is forwarded to Asterisk, a menu is played, then an extension is called exten => *,1,Background(beep) exten => *,2,Dial,SIP/Xliteextention@domain|30|mt exten => *,3,Voicemail(u10) exten => *,102,Voicemail(b10) Xlite rings, but if I pick up calls are not connected, asterisk shows ringing, Xlite shows Connected. If I press Hangup on Xlite asterisk senses that and brings the grandstream call to voicemail, I hear the voicemail prompt from grandstream phone. Reversing the process everithing works absolutely fine: if Xlite calls asterisk, then a call is made to grandstream ext calls are connected. To make some more tests I tried using a non natted xlite, it works, that's the reason why i suspect that nat is the problem here. Any idea ? -- Best regards, Alessio mailto:alessiof@interconnessioni.it

[Serusers] Running SER in chroot and separating SER with serweb
by zeusng 17 Feb '04

17 Feb '04

Having playing with for 2 weeks, I get the SER running as I want. The next things I am trying are: 1. Run SER in chroot mode with MySQL 2. Separate SER and serweb on two servers. With 1, I have a partially successful config. When I can start SER with /usr/sbin/ser -u ser -g ser -t /var/ser, I got A. positive result if the DB connection string is "sql://ser:heslo@127.0.0.1/ser". B. However, if I use the DB connection string as, "sql://ser:heslo@localhost/ser", I got the following error message: Feb 16 19:46:09 sip /usr/sbin/ser[2452]: connect_db(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) Fair enough, coz SER is in a chroot environment and cannot stat the MySQL UNIX socket. There is no /var/ser/var/lib/mysql/mysql.sock. But, what is the difference between localhost and 127.0.0.1 here? Both should resolve back to 127.0.0.1, right? Why one use UNIX socket and the other use DOMAIN socket? Also, should SER open the DB connection before chrooting itself? Also, when running in chroot mode, SER cannot use DNS to resolve hostname. I get the following errors: Feb 16 20:19:03 sip /usr/sbin/ser[2873]: INFO: fifo process starting: 2873 Feb 16 20:19:03 sip /usr/sbin/ser[2873]: SER: open_uac_fifo: fifo server up at / tmp/ser_fifo... Feb 16 21:01:13 sip /usr/sbin/ser[2867]: ERROR: mk_proxy: could not resolve host name: "iptel.org" Feb 16 21:01:13 sip /usr/sbin/ser[2867]: ERROR: uri2proxy: bad host name in URI <sip:gcc008@iptel.org> Feb 16 21:01:13 sip /usr/sbin/ser[2867]: ERROR: t_forward_nonack: failure to add branches Feb 16 21:02:09 sip /usr/sbin/ser[2867]: ERROR: mk_proxy: could not resolve host name: "iptel.org" Feb 16 21:02:09 sip /usr/sbin/ser[2867]: ERROR: uri2proxy: bad host name in URI <sip:gcc008@iptel.org> This is a result of doing INVITE sip:abcdefg@iptel.org SIP/2.0 from my domain. If I put an entry into my chrooted /var/ser/etc/hosts, the request goes fine. Is it because of my chroot environment (later in the mail) or I have to compile SER in static mode? 2. Have anyone successfully put SER and serweb on different boxes? There is no problem connecting to the DB. However, I'm not sure about the /tmp/ser_fifo part. I'm not a programmer and can only manage to understand php code, no programming. How do I work around the /tmp/ser_fifo when it is on another server? Chroot environment: [root]# ls -lR /var/ser /var/ser: total 16 drwxr-xr-x 2 root root 4096 Feb 16 19:41 dev drwxr-xr-x 3 root root 4096 Feb 17 17:30 etc drwxrwxrwx 2 root root 4096 Feb 17 17:26 tmp /var/ser/dev: total 0 srw-rw-rw- 1 root root 0 Feb 16 19:41 log crw-rw-rw- 1 root root 1, 3 Feb 11 11:44 null crw-r--r-- 1 root root 1, 8 Feb 11 11:45 random crw-rw-rw- 1 root root 1, 5 Feb 11 15:16 zero /var/ser/etc: total 48 -rw-r--r-- 1 root root 210 Feb 16 21:08 hosts -rw-r--r-- 1 root root 785 Feb 10 17:11 localtime -rw-r--r-- 1 root root 5834 Jul 7 2001 protocols -rw-r--r-- 1 root root 43 Feb 16 14:52 resolv.conf /var/ser/tmp: total 0 prw-rw---- 1 ser ser 0 Feb 17 17:26 ser_fifo Chroot resolv.conf: Nameserver 127.0.0.1 And yes, the DNS is running on localhost and happily serving request. Any comment?

[Serusers] pa module in ser-0.8.12
by Yoshiho Yoshida 17 Feb '04

17 Feb '04

Hello, I am working on SER and Jabber with MSN transport. There are some problems still unresolved, one is a URI parsing problem which I posted before as http://lists.iptel.org/pipermail/serusers/2004-February/005918.html I can not establish a communication wth MSN, but I wonder This problem also happens with jabber user. So if there is a delimiter which is defined as aliases (msn, jabber) in local part, the above problem happens. But I could chat between Windows Messenger with other Jabber user. It seems ser corrects the address. I think the next problem is Windows Messenger side, but I would like to know if anyone encounters this problem. 1. Windows messenger -> Message -> Jabber Messenger (other user) OK 2. Jabber Messenger -> Message -> Windows Messenger OK 3. Windows Messenger -> Message -> Jabber Messenger X There is no output packet from Windows Messenger at 3. Other problem is, I can not see the correct (online) status for Jabber users through jabber and pa modules. and I found a comment in the following mail. http://lists.iptel.org/pipermail/serusers/2003-September/002642.html It seems current pa module puts the status in the body as XML text. # U 10.196.4.201:5060 -> 10.196.5.30:15478 NOTIFY sip:10.196.5.30:15478 SIP/2.0..Via: SIP/2.0/UDP 10.196.4.201;branch= z9hG4bK32db.4e44d2c.0..To: "norika" <sip:norika@ser.software.com>;tag=76fb6 e8b-0911-486c-92b6-c9e1358e194a..From: <sip:fumina*jabber.software.com@jabb er.software.com>;tag=158f166cb27489bb7c6c624552186861-46b6..CSeq: 1 NOTIFY. .Call-ID: fe489e41-8303-4dd0-8876-6ecf3b1b6cd7@10.196.5.30..Content-Length: 350..User-Agent: Sip EXpress router(0.8.12 (i386/linux))..Event: presence. .Content-Type: application/xpidf+xml..Subscription-State: active;expires=18 00....<?xml version="1.0"?>..<!DOCTYPE presence PUBLIC "//IETF//DTD RFCxxxx XPIDF 1.0//EN" "xpidf.dtd">..<presence>..<presentity uri="sip:fumina*jabbe r.software.com(a)jabber.software.com;method=SUBSCRIBE"/>..<atom id="9r28r49"> ..<address uri="sip:fumina*jabber.software.com@jabber.software.com">..<stat us status="closed"/>..</address>..</atom>..</presence>.. # So Jabber side, they can read the presence status from ser with jabber and pa modules. Is this correct in ser-0.8.12? I downloaded unstable version of sip_router and try to run it, but it seems new pa requires own db tables. Does new pa module fix the above presence problem? and is there any enhancement?

[Serusers] libmysqlclient.so.10 and gateway
by Laurent BURGY 16 Feb '04

16 Feb '04

Hi, I am a french student and i've tried to install ser on a Solaris 8. The problem comes with the MySQL server installation ( i've downloaded binary 4.0.17 distribution, so no compilation). When i start ser after having modified the ser.cfg file there is a problem with libmysqlclient.so.10 which cannot be found. I've tried to find this library but the only one available is libmysqlclient.a . Maybe, i should try a source distribution or i forgot executing a script although i followed the installation process. Another question is about PSTN gateway, i am looking forward this kind of product the more sip-compliant and open as possible (contrary to mediatrix solutions). What do you think about Asterisk and Digium card or if you have any proposition... Please help me .... Sorry for my terrible english, laurent PS: french people can contact me directly to share about sip.
