[Haifux] Seminar Demos by Denis Girou
Hello
I'm trying to compile the Demos writed by Denis Girou.
And there are some packages that I can't find.
The File seminar.com use the next package:
\usepackage{pst-fr3d} % PSTricks 3D framed boxes
\usepackage{pst-grad} % PSTricks gradient mode
\usepackage{pst-node} % PSTricks nodes
\usepackage{pst-slpe} % Improved PSTricks gradients
\usepackage{semcolor} % Seminar colored slides
and others.
For example the package pst-fr3d I can't find.
Do you now this class ??, Where I can download it??
Any one compile the demos of Denis Girou??
Thanks
Gusti

[Haifux] A LaTeX to HTML tool that works
Hello list. I just want to tip you off, that there's a great tool for converting LaTeX to HTML. It's called TeX4ht, and it's nothing like LaTeX2html and friends. This one WORKS, even if there are nested macros, as most of us by-hand LaTeX authors have. It also generates beautiful output, including equations and graphics. The fantastic thing was that I managed to translate the 200-page manual of Perlilog to HTML, with no hassle at all (I have to admit that it took my about 30 minutes, but still, that's no time). TeX4ht also claims to translate to Open Office and MS Word, but I haven't tried either. The reason it works so smootly is that TeX4ht doesn't attempt to parse the input itself, but comes in somewhere in the DVI stage. So it's not TeX rewritten, like other tools I've seen, but an extension of the well-known, stable TeX. For all of you who have documents published in LaTeX, PS and pdf, this is the time to publish them in HTML as well. Keep in mind that google parses these documents rather poorly. Most of us want to be found if someone looks for what we've written about. I got my copy from http://at.rpmfind.net/opsys/linux/RPM/suse.com/i386/8.1/suse/i586/tex4ht-20020613-68.i586.html . It's intended for SuSe 8.1, but it worked nicely on my RH7.3 even though I forced installation, ignoring the failed dependency of the te_latex package (almost all files in the latter exist on my system). I also recommend to download the source at http://www.ctan.org/tex-archive/support/TeX4ht/?action=/tex-archive/support/ or similar, because there are some documentation files in that package. Beware that the ZIP file opens flat in the current directory. Having the package installed, simply go htlatex.sh myfile.tex and it will behave very much like good old LaTeX. If you want a split of sections into separate files, simply go htlatex.sh myfile.tex html,2 for a file on each section, or change the 2 to 3 to get a file for each subsection. The result is surprisingly good.

Re: [Haifux] A suggestion for a lecture - How to protect your network, using IPtables.
Hello Adir. As you may recall, I gave a lecture about iptables, which covered both masquerading and some basic firewalling. But it seems like iptables is a very popular topic: The knockout winner of google searches, that bring people to my site, is exactly iptables and masquerading (since I keep my lecture slides there as well). So obviously, there is a demand. And yes, I treated firewalling as a side issue in my lecture. After all, we trust our fellow internet users, don't we? ;) Do have a look on my slides. You may find the sketches useful. It seems to me that those who are with Haifux for a long time will not be so interested, while the Staying-in-Linux audience can find it very useful. Besides, that's your chance to get a slot before May. ;) And what I see happening is that we get two tracks of lectures: One for experts and one for newbies. I think this is a great thing. Maybe we should make this official. Eli -- Web: http://www.billauer.co.il -- Haifa Linux Club Mailing List (http://www.haifux.org) To unsub send an empty message to [EMAIL PROTECTED]

But it seems like iptables is a Yes, I remember that. And yes, I treated firewalling as a side issue in my lecture. After all, we trust our fellow internet users, don't we? ;) Ofcourse we do ;) Firewalling is not going to be a side issue of my lecture. I will focus more on the filter options part of IPTables, actually. Do have a look on my slides. You may find the sketches useful. I just had a look. Your slides are very good and I remember them. What I plan to talk about is in totally different view. First of all - I am not going to mention NAT, neither mangling at all. I won't talk about masquerading but I'll focus on filtering, giving a wide introcution regarding the logic behind IPtables, I'll describe useful commands and give examples as well. At the 2nd part, I wish to describe some attacks scenarios and how to defend against them using IPtables. I'll also want to describe the concepts of building a firewall, using IPtables. I hope that there are people who like chains, in addition to traditional code :) It seems to me that those who are with Haifux for a long time will not be so interested, while the Staying-in-Linux audience can find it very useful. Besides, that's your chance to get a slot before May. ;) Maybe. I'm not sure who wants to hear about it and who doesn't. It's actually a very relevant Linux subject which I believe that even the veteran users (who wish to know better what IPtables is) will be glad to hear about (Google proves my point ;). As for slotting it before May - I'm afraid that I won't have time to start working on it before March (exams, etc), so starting to work on it afterwards, while getting scehduled in the end of May, is great for me. Otherwise - I would have considered to give it earlier. And what I see happening is that we get two tracks of lectures: One for experts and one for newbies. I think this is a great thing. Maybe we should make this official. Maybe. It sounds like a good idea. Anyway, regarding my lecture(s), if I split it to two, naturally there will be a basic lecture and a more advanced one. I'll be glad to give both as regular lectures and see later where and how it fits to a SiL series (of next year).

I will not repeat on his topics at all.. There is a lot to cover in IPtables, and extremely little was talked regarding what I want to talk about in great expend, and more that he didn't talk about at all (in my opinion). It's almost like saying that we are talking about Linux all the time :) Adir, If March (the next SIL slot) is too soon, we can schedule your IPtables lecture as a SIL lecture a bit afterwards, but May 31st is a date reserved for a regular lecture (veteran, advanced, new, whatever you may call it). As I said, I don't mind about the status of the first lecture (as I see it, it is going to be two lectures). However the 2nd one (attacks scenarios and ways to prevent them, in addition to building a real firewall via IPtables) is considered advanced because it assumes knowledge of IPtables, its important concepts or at least the previous lecture. What I suggest, in this case, is to give the advanced lecture on a regular date, and to give the basic lecture a week before, just like we do with the SiL, unless people want the two lectures to be scheduled regular, and in a difference of two weeks. In this case, I will like to get two regular dates so people won't get tired after 4 lectures in a month (a lecture every week). In addition to that, before we decide that it's good for the SiL or not, I'd like to give the lecture in order to know how good it is (it will be a first run, after all). If it's going to be good enough, we can schedule it once again as a SiL lecture for next year, like we did with other successful (or wanted) lectures. However, since most of the Haifux veterans have already enjoyed Eli's lecture, and can go to the slides to refresh their memory (no need to hammer that info inside heads), I see no reason for a causing a drought of lectures (4 or 6 weeks between new topics). Eli's slides are not going to overlap with mine, as I will give a totally different view. It's just like saying that advanced networking shouldn't be covered because we talked about it once. I don't need to say that advanced networking is a general subject. Also iptables, in this case. Besides that - Eli's lecture was given in April 2003 (28/4/2003, if to be exact). That makes it 9 months, not 6 weeks...
