OnionCat is ported to Windows (Cygwin)


OnionCat is now ported Windows. It runs within Cygwin POSIX-like Environment and first tests were successful. The code is merged into OnionCat SVN trunk release 486.

(*) For installation first install then OpenVPN TAP driver which is included in the OpenVPN Windows package (see www.openvpn.org).
(*) Install Cygwin and add the gcc, make, and subversion packages.
(*) Apply the IPv6 extension patch (http://win6.jp/Cygwin/index.html) to Cygwin.
(*) Add the TCP/IPv6 protocol to the TAP device in Windows network configuration.
(*) Install Tor/Vidalia.
(*) Checkout OnionCat from SVN.
(*) ./Configure and make it as described on the OnionCat project page (https://www.cypherpunk.at/onioncat/wiki/Download)
(*) Configure and run Tor and OnionCat as described on OC project page (https://www.cypherpunk.at/onioncat/wiki/Configuration)

We’ll further improve code and build installation packages for WinOC.
Keep in mind that it is not tested very well and bugs may be included.
If you’d like to attend to OnionCat IRC you might use KVIRC. It worked perfect in our test environment.

Have fun using OnionCat on Windows!

OnionCat Debian/Ubuntu Packages available

Nun gibt es OnionCat auch als Debian Paket, um genau zu sein, Ubuntu 8.10 (intrepid). Einfach hier die Einträge für die “/etc/apt/sources.list” holen und die Kommandos “apt-get update” und “apt-get install onioncat” ausführen und OnionCat ist als Daemon installiert.

Debian Packages should arrive soon!

If you want to build a Debian Package,  just do a “svn co https://www.onioncat.at/svn/onioncat/trunk onioncat” change into the OnionCat Directory and issue the “debuild -us -uc” command, you should get a package  in ../onioncat.



Applying OnionCat at the IPv6 Application Contest


The German IPv6 Council holds an IPv6 application contest . The contest should generally support and advocate the IPv6 protocol.
We are going to apply for this contest with OnionCat.

Lenovo X301 with Ubuntu/Debian/Linux and working GPS


I got a x301 since quite some time, and iam very happy with it! since the integrated ericsson f3507g is capable of doing AGPS (Assisted GPS, more info @ http://en.wikipedia.org/wiki/AGPS)

here are the steps which need to be done to enable AGPS


Now you can use gpsd to connect to your modem Device!

thanks to nikolai!

OnionCat goes GarliCat

Wir befinden uns im Gespraech und in Diskussion mit den I2P Entwicklern, um OnionCat I2P faehig zu machen. Ich habe mit der Entwicklung dafuer bereits begonnen.We are in permanent discussion with the I2P developers to make OnionCat also work with I2P. I already started development.

The Twelve Networking Truths

Status of this Memo

This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.


This memo documents the fundamental truths of networking for the
Internet community. This memo does not specify a standard, except in
the sense that all standards must implicitly follow the fundamental


The truths described in this memo result from extensive study over an
extended period of time by many people, some of whom did not intend
to contribute to this work. The editor merely has collected these
truths, and would like to thank the networking community for
originally illuminating these truths.

1. Introduction

This Request for Comments (RFC) provides information about the
fundamental truths underlying all networking. These truths apply to
networking in general, and are not limited to TCP/IP, the Internet,
or any other subset of the networking community.

2. The Fundamental Truths

(1) It Has To Work.

(2) No matter how hard you push and no matter what the priority,
you can’t increase the speed of light.

(2a) (corollary). No matter how hard you try, you can’t make a
baby in much less than 9 months. Trying to speed this up
*might* make it slower, but it won’t make it happen any

(3) With sufficient thrust, pigs fly just fine. However, this is
not necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead.

(4) Some things in life can never be fully appreciated nor
understood unless experienced firsthand. Some things in
networking can never be fully understood by someone who neither
builds commercial networking equipment nor runs an operational

(5) It is always possible to aglutenate multiple separate problems
into a single complex interdependent solution. In most cases
this is a bad idea.

(6) It is easier to move a problem around (for example, by moving
the problem to a different part of the overall network
architecture) than it is to solve it.

(6a) (corollary). It is always possible to add another level of

(7) It is always something

(7a) (corollary). Good, Fast, Cheap: Pick any two (you can’t
have all three).

(8) It is more complicated than you think.

(9) For all resources, whatever it is, you need more.

(9a) (corollary) Every networking problem always takes longer to
solve than it seems like it should.

(10) One size never fits all.

(11) Every old idea will be proposed again with a different name and
a different presentation, regardless of whether it works.

(11a) (corollary). See rule 6a.

(12) In protocol design, perfection has been reached not when there
is nothing left to add, but when there is nothing left to take

Security Considerations

This RFC raises no security issues. However, security protocols are
subject to the fundamental networking truths.

OnionCat hat jetzt eine eigene SeiteOnionCat got his own new page

Nach dem Vortrag auf dem 25C3 wurde die OnionCat Hauptseite verschoben, sie ist nun unter http://www.cypherpunk.at/onioncat/.

After our talk at 25C3 I moved the OnionCat primary site. It’s now implemented using Trac at http://www.cypherpunk.at/onioncat/ .
