Hi, First i want to welcome two new developers to this list, it would be great if both of you can give us informations about your plans / ideas for stegfs and how you can help with developing from your point of view. Some personal informations would be also very helpful :-) --=20 Mit freundlichen Gruessen / yours sincerely Sebastian Urbach ------------------------------------------------------------------- Religion is something left over from the infancy of our intelligence,it will fade away as we adopt reason and science as our guidelines. ------------------------------------------------------------------- Bertrand Arthur William Russell (1872-1970), Britischer Mathematiker, Philosoph und Schriftsteller |

Dear Open Source developer I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate. You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it. With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development. With many thanks for your participation, Benno Luthiger PS: The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/. We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list. _______________________________________________________________________ Benno Luthiger Swiss Federal Institute of Technology Zurich 8092 Zurich Mail: benno.luthiger(at)id.ethz.ch _______________________________________________________________________ |

Hello everyone, It looks like we're waking up after a long period of inactivity, and something is happening at last. Hello to the new developers! I've recently posted some code to the project CVS. Please, everyone, have a look at what I've done, and think about it, and tell me whether it is of any use or not. My personal opinion is that, as none of us have got much free time to donate to this project, we should aim to produce something that is simple and easy: if we go for a complicated design then it will never get done. I think that what I have done so far could be developed in this way. But it will be of no use at all if it has some cryptographic flaw that I have not spotted. John |

Hi folks, first of all, I have to admit, that I am glad that you started this project! I really would like to have the StegFS ported to a recent kernel. Two years ago, I started porting it to 2.4.18, but since the VFS layer was a very fast moving target at that time, I gave up frustrated (I had a fully compiling kernel module, which constantly oopsed at various areas at the intersection of steganograpic extensions with ext2). However, this porting time offered me a deep look inside the ext2 FS and the steganographic extensions from StegFS. I would like to offer my support: I might help in programming, testing or even documentation. However, I have only limited time available. But I hope, together we will manage to port this FS. I will start review the recent discussions I gain the knowledge what the current status is. Ciao Stephan -- | Whenever you eliminate the impossible, whatever | | remains, however improbable, must be the truth. | |

OK, I *think* I've loaded it into Sourceforge. At least, if I type
cvs co stegblock
then it checks out my files (and a few empty directories that I made by
mistake).
But if I use the web-based CVS browser then I can't see it. Maybe
someone with more knowledge of cvs can fix this ?

Hi, I send a mail a few minutes ago with the subject "Coding". Theres a really interesting attachment which should be read by everybody on this list :-) It seems as if we will have an new developer in the next 1 or 2 days on this list with the same experience like a few people from us ... -- Mit freundlichen Gruessen / yours sincerely Sebastian Urbach -------------------------------------------------------- Wir haben massenhaft Leute, die sich fuer Gleichheit und soziale Gerechtigkeit einsetzen - aber kaum jemand fuer Freiheit. -------------------------------------------------------- Prof. Dr.-Ing.

Hi, thank you for letting me become a StegFS developper. Yesterday I was just looking to become a user :) . Some infos about me: I'm 34 years old and working at a small company developing software mostly in Java (www.fumix.de). We're also doing some consultancy stuff, but always focused on software development. I am married and have 2 little children and live in Weinheim near Heidelberg in South West Germany. My family will also be the limiting factor for my engagement in this project - so don't think that with my arrival in this project everything will speed up much. Except for computers and family I got one other hobby I don't spent much time upon: Astronomy. So what can I do for this project: * Increase the wishlist that's for sure :) * Taking part in the discussion about the basics of the filesystem. * Maybe some developing - BUT... ... I haven't been programming in C for years and I have never developped a driver, kernel module or anything else near an OS kernel :( But I'm curious in doing so and try to find some time learning it. I think I will start working through the papers to see if my ideas are already included. I'm also going to checkout the source in the CVS to browse over it to get a feeling for the code. Before playing around I also have to get myself 2.6 kernel, since for now I'm still stuck with a 2.4 kernel. Cheers, Michael Am Mittwoch, 5.

Let's ask the guys with the better programming skills. Andrew and Andreas, could you please make some comments ? Im really sure that my personal programming skills are not good enough to judge the technical criteria of this idea, but it sounds logical to me. Im going to provide any possible assistance, as far as i can, for everyone who is going to start coding and yes im doing alle the donkeywork if someone tells me what to do :-). Testing, writing StegFS documentation and all that :-) StegFS ist a great concept and there are a lot of people which are sending mails to me regarding StegFS and the project future. Andreas and i started the project on sourceforge because we are absolute sure that a StegFS version for the actual kernel is something the world is waiting for... Andreas and i are willing to give everyone, who is interested, project leader permission because we dont want to slow down the project progression. It would be a pleasure for us to have an active project leader beside us who is able to push the project ... Our priority is to do the best for the project. If someone is interested, just give us a wink. -- Mit freundlichen Gruessen / yours sincerely Sebastian Urbach -------------------------------------------------------- Wir haben massenhaft Leute, die sich fuer Gleichheit und soziale Gerechtigkeit einsetzen - aber kaum jemand fuer Freiheit. -------------------------------------------------------- Prof. Dr.-Ing.

Hello everyone, We're not getting on very well with this stegfs thing, are we? The project has been set up for a year, and nothing has happened. OK, here's my idea. Feel free to tell me I'm stupid if you don't agree. This project is just too hard. A file system like ext2 is very complicated. Our aim is to make something even more complicated, with encryption and so on added. The Linux developers have put a huge amount of effort into making ext2 work well, and we don't have the time or resources to match that. Even if we got something to work, we would always be playing catch-up: the ext2 developers keep changing their code to improve it, so we would have to keep changing our code to match. That's why the original version by Andrew McDonald is out of date and can't be used any more. So: I suggest we try something simpler instead. We shouldn't make our own file system. The loopback drivers lets you make a block device out of a file (or disk partition). Suppose we modified it so that the blocks of the block device were spread around the file at random, instead of being in the correct order. Then you could make a file system on top of the loopback device, and the blocks of that file system would be randomly distributed around the original file or partition. Now, with a bit more work, we could make another file system that used some of the other blocks of the original file. And then another one, and so on. So we've got lots of different file systems all occupying the same underlying file or partition. If everything is encrypted, then an attacker won't be able to tell how many file systems there are: we could show him the harmless files in some of them, and deny the existence of the others. Does this make sense as an idea? I think Andrew McDonald said somewhere that he thought of doing something like this, but changed his mind, so maybe there's some problem I haven't thought of. Anyway, I think this would be a lot easier that the file system idea. It's just a modification of the loopback device driver; all of this fits into one source code file, so it's a lot less complicated than any file system. Any comments? John |

Das sind gute Fragen, wir sind noch in der theoretischen Planung und kommen leider in den letzten Monaten so gut wie =FCberhaupt nicht dazu was zu machen.

Wir bedauern das wirlich sehr weil die Notwendigkeit einfach gegeben ist f=FCr ein StegFS aber wir es zeitlich einfach nicht besser hinkriegen.

Hi together,
I'm interested in using the StegFS, but looking into the CVS there was no
activity for half a year or so. Is there someone still working on the project
and is there a usable version available?

Hi StegFS guys! Some words about me as requested: I'm J=E1nos Horv=E1th-Varga from Budapest, Hungary. 24 years old, just graduated at the Technical University of Budapest as M.Sc. in information technology. My thesis was application development for IP telephony systems (mostly for Cisco and Polycom). Right now I'm working for a small hungarian Ltd, designing, implementing and supporting IP networks built from Cisco devices. I got CCNA and CCDA for this job. In spare time I am developing a workflow management system using IIS, PHP, MSSQL. (dont flame on me, iis and mssql were constraints for me) I started programming in BASIC, later Z80 assembly, after I moved to c64 from ZX Spectrum and joined to the demoscene. After years spent with demowriting, the university began. x86 assembly, pascal, c, c++, little java were the different programming languages I had to use there. I've been using Debian Linux since 1998 on several servers and also on my desktop PC. People say I am a Linux fanatic. :) I am interested in steganography and stegfs for some month but still had no time to start to read the source of stegfs. I have no experience in kernel programming but it has been a dream to learn it for years. I hope this is the right moment and project to do so. Please don't wait too much coding from me in this authum until I fall into line with ext2fs and stegfs sources. I will send some ideas soon to the list for discussion. Yours, J=E1nos Ps: Some personal infos at http://c64.rulez.org/~janee/ :-) |

Hi, I would like to welcome Horvath Varga Janos as a new StegFS Developer. It would be great if you can tell us a little bit about you and your developing background :-) Feel free to add new ideas to our papers in CVS. As you all may have noticed, there are some new files uploaded in the CVS. The CVS contains now the actual ext2 files from the 2.6 kernel. We are trying to understand what's going on in that files right now :-) One mission goal had changed a little bit. 2.4 Kernel developing is not realistic anymore from our point of view, so wie chanced to 2.6 as shown on the project webpage (http://stegfs.sourceforge.net) -- Mit freundlichen Gruessen / yours sincerely Sebastian Urbach -------------------------------------------------------- Real men don't take backups.
