SIP+NAT mit kphone funktionieren (fast)

by Karl Lunger

Hallo VoIP ist eine tolle Sache, ueber die wir auf dieser Liste schon mal diskutiert haben. Ich hab jetzt bei sipgate.at ein Account angemeldet und wollt die ersten Tests machen. Zuerst hat nichts funktioniert, nach dem Oeffnen einiger Posts bei den iptables des Clients und der Definition von port forwarding auf dem Router funktioniert das Anrufen eines Telefons jetzt fast. Das Telefon nimmt den Anruf entgegen und wenn ich im richtigen Augenblick der Gespraechsannahme etwas ins Micro spreche kommt es am Telefon an, aber alles Weitere kommt nicht zum Telefon. Die Kommunikation vom Telefon zu kphone funktioniert aber, d.h. ich hoere am PC alles, was ins Telefon diktiert wird. Die Verbindung bleibt ca. 30 sec. erhalten, bricht dann zusammen. kphone stuerzt waehrend des Tests noch vor dem Zusammenbruch der Verbindung ab bzw. reagiert weder auf die Tastatur, noch auf die Maus. kphone kann nur mehr abgeschossen werden. An kphone liegt es hoffentlich nicht, ich hab mehrere Versionen und Compilate getestet. Der Client ist ein Fedora Core 3, der Router ist ein Zyxel Prestige 650R-31. kphone arbeitet wie empfohlen mit UDP (mit TCP hat es auch nicht funktioniert) und es ist der STUN-Server angegeben. Der Client hat die private Adresse 172.16.170.71. Im Netz gibts zum Problem mit NAT einiges zu lesen, aber ein so unsymetrisches Problem mit einer Loesung hab ich nicht gefunden. Interessant ist die Ausgabe von kphone in die Console. Dort findet man immer wieder "UDPMessageSocket::SetTOS: Operation not permitted", so als ob wieder mal etwas nicht durch den Router ginge. In /var/log/messages wird nichts aufgezeichnet. Hat jemand eine Idee zum Problem oder eine positive Erfahrung mit einer aehnlichen Configuration hinter einem Router? Im Anhang sind folgende Dateien angehaengt: 1. zyxel_nat.txt: port forwarding am Router 2. kphonerc: die Datei ~/.qt/kphonerc 3. iptables-L_notebook.txt: iptables -L auf dem Client 4. prot_kphone.txt: Ausgaben von kphone in die Console 5. dump.txt.gz: tcpdump -i eth0 auf dem Client Danke Karl -- .-. /v\ L I N U X // \\ >Phear the Penguin< /( )\ ^^-^^ karl (aet) lunger (dot) org http://www.lunger.org http://www.gobbz.org Menu 15.2 - NAT Server Setup Rule Start Port No. End Port No. IP Address --------------------------------------------------- 1.

[Fwd: EU software patents: please express gratitude to Poland]

by Patrick Ohnewein

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------- Original Message -------- Subject: EU software patents: please express gratitude to Poland Date: Sun, 26 Dec 2004 14:02:24 +0100 From: Florian Mueller <florian.mueller(a)nosoftwarepatents.com> To: <info-gnu(a)gnu.org> Please take a minute to visit http://thankpoland.info and express your gratitude to the Polish government for its courageous last-minute intervention in the Council of the European Union against software patents on Tuesday (21 Dec). Poland prevented, at least for the time being, the adoption of a legislative proposal that would legalize software patents in the EU. The respective text looks like it forbids software patents while it actually codifies almost all of the excuses with which the European patent systems (European Patent Office and national patent offices) have been granting software patents for a number of years, contrary to the European Patent Convention. The EU Council could not have turned that proposal into an effective law right away. The Council's "Common Position" would have to go back to the European Parliament for a second reading, in which the majority requirements to make any amendment are however very high. What the Polish government did was very unusual in EU politics. The EU Council has a two-tiered approach to decision-making, and in the entire history of the EU there has been no more than one case so far in which a political agreement (which was reached on software patents on 18 May 2004) was not turned into a formal decision later. So Poland accepted to pay a diplomatic price for potentially preserving the freedom of software developers. No other country was prepared to do so. Please also participate in the "Thank you, Poland" campaign if you are not an EU citizen. The EU's legislative process on software patents will have a major impact on what will happen with patent legislations worldwide. If all of the first world is under a US-style software patent regime, emerging markets will follow. This is the chance to rein in the patent system by democratic means, which would also increase the chances of a future patent reform in the US.

Hallo Liste! Peter Pohl, auch er stolzer Besitzer eines Motorola GNU/Linux Handies, hat mir folgendes Dokument gemeldet. Motorola A768i and GNU/Linux: http://tux.medhas.org/static/a768i.html Es beschreibt die Interoperabilität zwischen dem A768i und GNU/Linux. Da dieses Gerät mit dem A760 verwandt ist, habe ich es in die entsprechende WiKi Seite aufgenommen: http://member.lugbz.org/wiki/Motorola-A760 Happy hacking! Patrick

Brevettabilita` del software

by Paolo Dongilli

Vi inoltro la seguente mail. Paolo. -----Original Message----- From: UNILEX(a)LIST.CINECA.IT [mailto:UNILEX@LIST.CINECA.IT] On Behalf Of Michele Marchesi Sent: lunedì 20 dicembre 2004 8.51 To: UNILEX(a)LIST.CINECA.IT Subject: brevettabilita' del software Cari amici, ho appena mandato al Ministro Alemanno (ministro.staff(a)politicheagricole.it) la lettera acclusa, perche' domani i ministri dell'agricoltura europei (!) dovrebbero votare sulla brevettabilita' del software, una norma capestro che metterebbe seriamente a rischio i piccoli produttori e le comunita' open source. Invito chi e' d'accordo a inviare lettere simili al Ministro, e a registrarsi sul sito http://demo.ffii.org/support.php Saluti Michele Marchesi Ill.mo Sig. Ministro, domani i Ministri dell'Agricoltura dell'U.E. dovrebbero votare sulla direttiva circa i brevetti del software, con un voto di tipo A, senza discussione, anche se non c'e' piu' una maggioranza qualificata di paesi membri in favore. Il testo in votazione prevede una brevettabilita' del software senza limiti pratici, con varie difese contro eventuali tentativi di limitazione. Se questo testo sara' approvato, sara' molto difficile ottenere una direttiva ragionevole in un secondo tempo. Il software e' gia' protetto dal diritto d'autore, e la sua brevettazione e' utile solo alle grandi corporazioni che vogliono perpetuare il proprio monopolio, e che hanno i mezzi per minacciare e sostenere cause verso le piccole software house e le comunita' di sviluppo "open source". Nel caso del software, la brevettabilita' NON e' uno strumento di diffusione delle conoscenze, ma di blocco della creativita' e di perpetuazione dei monopoli. Come professore di Ingegneria del Software all'Universita' di Caglari, sono particolamente preoccupato della situazione che si sta venendo a creare, e Le chiedo di considerare bene il significato del voto. Maggiori informazioni si possono trovare su http://demo.ffii.org/letter.html Ringrazio anticipatamente per l'attenzione, e invio i miei piu' distinti saluti Michele Marchesi -- ________________________________________________________ /\ \ \_| Prof. Michele Marchesi | | DIEE - Univ.
