[Users] TCP-alias and NAT - one more try to get an answer

by Alexander Ph. Lintenhofer

Hi All, I just wanted to ask you once again about the TCP-alias riddle. I found out, that there is a problem with the combination of fix_nated_contact(), force_tcp_alias() and NAT: Imagine following situation: Alice behind NAT: socket 172.16.0.6:2421 Nat-Box translates this to 192.168.0.13:6007 The Outbound-Proxy of Alice is 192.168.0.1 Bob is registered with 192.168.1.1 1.) Her INVITE: ==================================================================== INVITE sip:bob@192.168.1.1:2331;transport=tcp;line=wxqurd1s SIP/2.0 [...] Via: SIP/2.0/TCP 172.16.0.6:2421;received=192.168.0.13; branch=z9hG4bK-wm9jcstcboys;rport=6007 From: "Alice" <sip:alice@atlanta.com>;tag=sufzmxi0us To: "Bob" <sip:bob@biloxi.com>;tag=c9550czwtn [...] Contact: <sip:alice@172.16.0.6:2421;transport=tcp;line=fyyuh6tl> [...] ==================================================================== 2.) fix_nated_contact() doesn't work with TCP (look at nathelper.c). force_tcp_alias() now creates following tuple as TCP-alias: 192.168.0.13:6007 to 192.168.0.13:2421 Reason: The TCP-alias is not built solely from the Via-header as suggested in the draft. The portnumber is taken from the Via-header and the IP-address is taken from the source of the incoming datagram. I read it in the sourcecode and assured it by contacting Andrei! 3.) So as a result of the notfixed Contact-header of Alice's INVITE the BYE of Bob is addressed to 172.16.0.6:2421. But no TCP-alias exists for this socket :-( 4.) I made following test by rewriting the Contact-header.... ==================================================================== if (method=="INVITE") { replace("Contact: <sip:alice@172.16.0.6:2421;transport=tcp;", "Contact: <sip:alice@192.168.0.13:2421;transport=tcp;"); } ==================================================================== ...with success. Now TCP-alias works as you can see on my Ethereal-trace below! Compare the destination port of the packet to the destination port of the RURI! ==================================================================== [...] Transmission Control Protocol, Src Port: 5060 (5060), Dst Port: 6007 (6007), ... Session Initiation Protocol Request-Line: BYE sip:alice@192.168.0.13:2421;transport=tcp;line=fyyuh6tl SIP/2.0 Message Header [...] From: "Bob" <sip:bob@biloxi.com>;tag=kcsveifugd To: "Alice" <sip:alice@atlanta.com>;tag=ricaq5cy15 Contact: <sip:bob@192.168.1.1:2331;transport=tcp;line=wxqurd1s> [...] ==================================================================== Another solution: Comment the lines in nathelper.c which force the return in case of TCP or TLS. Now all works well! But why?????????????? regards, Philipp

[Serusers] LDAP authentication (without Radius)

by Felipe Louback

I'm working in a VoIP solution here in my university and we have a wide LDAP base and I am thinking about using it for I found on the internet Ldap/Ldaps modules for SER (http://www.ethworld.ethz.ch/technologies/sipeth/ser_modules/ldaps), but I am afraid that I could only use them for lookups and not direct authentication. I guess I could use radius for authentication but I dont know if installing a radius server "just" for this would be worth the effort. Does anyone know if there is a way to authenticate users in a LDAP server without using Radius? I mean, could I use SER directly with LDAP without using RADIUS?

[Users] openser 1.0.0 packages generation

by Daniel-Constantin Mierla

Hello everybody, I would like to ask all of you that have access to different OS distributions to help with package generation. Please reply (personally if you prefer better this way) with OS name, version and architecture. We are looking mainly for common used distributions: Debian - testing (the other two are accounted already) Redhat Suse Open/NetBSD (FreeBSD accounted) SUN/Solaris Gentoo ... We will help as much as possible with guidelines. We would require tomorrow an early compiling on all available systems to fix eventual warnings. Cheers, Daniel

[Serusers] variables with avp_check

by Joao Pereira

Hello, I want to use variables in ser.cfg and I m trying to use avpops for it # first by giving the variable "var" the value "internal" # string mysar = internal; avp_write("internal", "s:myvar"); # and checking this variable later: # if (myvar = internal) if (avp_check("s:myvar", "eq/internal/i")){ But this never enters in this if, can someone tell me the way to do it? Or where is some documentation about avpops (iptel.org/ser doesnt have). Thanks Joao Pereira

[Serusers] OpenSER infrastructure dimensioning

by Vanlandschoote Michel

Hi, we are considering OpenSER for offering free SIP-based voice, video and IM services and I am trying to get an idea of the project cost. The components we need are: - SIP stateful proxy + registrar server - location & presence server - simple2jabber - media proxy for symmetrical NAT traversal - (perhaps I forgot something here?) We'll rely on external gateways for PSTN access so that is not to be taken in consideration here. Now can somebody give me an indication on the server park dimensioning? In other words, how many SIP servers, media proxies, ... would I need per 10000 subscribers? The server platform could be e.g.: - operating system: Linux - hardware: HP ProLiant DL380 Generation 3 (single CPU with 1GB RAM) but of course any equivalent would do as well. I also have a second question: which organisations in Europe offer commercial support for OpenSER? Hope this forum is the right place for this kind of questions... I really appreciate your input, Michel ************************************************************* Dit e-mail bericht inclusief eventuele ingesloten bestanden kan informatie bevatten die vertrouwelijk is en/of beschermd door intellectuele eigendomsrechten.
