Re: relayd layer 7 http proxy and filtering questions
As a test, the URL or path filtering can allow /, *.html and *.jpg. We are unable to figure out how to get relayd to allow only these types of files, and deny any other access. Same question here as I was unable to find answers yet either, after studing the man pages, trial-and-error testing and finally looking at the source of relayd. But before giving up and returning to Pound, I was about to contact the authors (reyk@, pyr@) for guidance. Thus I'd be interested in any hints and working examples, too. Then, for one outcome, we might try to improve relayd's man page section about filtering. Thanks, Rolf
Re: using openbsd to make presentations
Hi, yes, I also thought of something similar, but the result is that gs produces slides which are not smooth, i.e. you can almost see the pixels. You can increase the resolution but this makes also the slides heavier and then you run into the same snag...

For instance, to generate the pnm files: gs -r248 -sDEVICE=pnmraw -sOutputFile=%d.ppm -dTextAlphaBits=4 \ -dGraphicsAlphaBits=4 -dNOPAUSE doc.ps -c quit for i in ?.ppm; do mv $i 0$i done then to display them: qiv -f -i ??.ppm using space and backspace keys you can switch between slides very quickly even on a slow machine. Furthermore you can skip 5 slides using page-up and page-down keys, which is very handy when somebody asks you to go a particular slide. hth, -- Alexandre

Of course you know that Acroread is not slow at all...that is my solution, not something I like though. What about evince? Evince is not slow either. xpdf is blazing fast on my gentoo. So it looks like there is something wrong with xpdf on OpenBSD. I have never played with apm(8), so I am not so sure what is to be done. As to mgp and LaTeX beamer, well I think there is no question. ;) mgp is quite painful since many people cannot get that running properly under linux and it never works on Windows. I find this a problem when I want to distribute the slides. And they are completely lifeless when you view the html... OTOH LaTeX Beamer is superb. But bear in mind that nowadays you have www.slideshare.net and I uploaded my jQuery talk and they completely fucked my slides. I think it converts it into flash and they have no clue what to do with slide overlays. Anyway I got some new ideas from this thread, that of trying out the seminar class and other LaTeX packages. Let me try my luck. As to scalable fonts, I have never had a problem with fonts breaking under xpdf. My slides invariably have pictures in them. It is just that xpdf gets angry when you view your slides in fullscreen. I have never seen the source of xpdf but it is in the back of my mind. If I get around to it, I want to fix whey xpdf is slow on OpenBSD but fast on gentoo. Or it might be that I have never played with apm.

But if there are big/complex graphics, then it can be slower. (The 10 seconds is only for some really nasty graphics files.) I have observed something around 3 to 4 seconds. It is not exactly painful but distracting. All my slides have pictures or source code, so xpdf is mostly unacceptable. It is very fast when you don't view fullscreen , so the issue is in scaling. In fact I would also venture to say that color pictures give a lot of fun and life to your boring technical talks be it math or software or hardware or even if you are making a sales/marketing pitch.

Re: using openbsd to make presentations
Nice to see that such a thing exists... I was thinking of doing something similar by myself... nevertheless the installer of mathml seems to be a bit lame and I am a bit worried about the portability of the final file. Sometimes, as you know, you are asked to not plug in your laptop, so that speakers do not waste time trying to configure X and in those cases they ask you for a pdf (or even ppt, buerk!) file which they will copy over to the conference laptop... Otherwise it seems indeed a very nice idea. 2008/3/19, Matthew Szudzik [EMAIL PROTECTED]: Question: Do you have any recommendation / suggestion to prepare talks to be shown in a projector including mathematical equations, plots and, eventually, movies (I can live without this last point)? HTML is probably the most portable solution for your problem, and movies would work fine too (using VLC's Mozilla plug-in). Graphics display quickly and Firefox has MathML for displaying equations, but special fonts are required, and I'm unsure if anyone has ever tried to install them on OpenBSD (I certainly haven't). An example of MathML used in HTML is at http://pear.math.pitt.edu/mathzilla/Examples/markupOftheWeek.mhtml Personally, I use Mathematica on my OpenBSD laptop--it has a nice presentation mode and renders equations beautifully. Of course, it's proprietary software that costs money, so it's not for everyone.

As you know teTeX is dead for about three years now and the TeXLive is official TeX distribution for Unix maintained by TeX community. TeXLive is available only from ports for OpenBSD 4.2. However you will have to use port for 4.3 current (soon to be release) as I stumbled upon a bug in Powerdot class of presentation. The bug was in TeXLive source code and was well documented. It is already fixed by port maintainer for OpenBSD 4.3. As far as I know TeXLive will be regular package (you will not need to use ports) starting OpenBSD 4.3. This is only second Unix like system after Debian to have fully functional TeXLive thanks to Edd Baret porter of TeXLive for OpenBSD. On the last note I recommend that you install full TeXLive which is about

Well in all honestly lots of thing were not working properly due to the fact that most new packages require fonts and packages only included in TeXLive or if you like in MiKTeX 2.8 for Windows. teTeX was unmaintained for more than three years so of course the things that were coded in last couple of years didn't work on teTeX. I share your frustration about the fact that Acroread is also required. I think, I mentioned this in my first post. Xpdf is just not going to cut for lots of these new Latex packages because people who use them are working on Windows. If you ask me personally that is just poor coding but I unfortunately have to relay on others to write macros for TeX. The best thing is of course if you could write your own macros and packages. Finally, my students are using very simple trick to show their movies in my class. They collapse slides all together, start MatLab and play their animations from there. Obviously MatLab is not free software but I can not force anybody to use FreeMath or SciLab (Not even ported for OpenBSD). If you look older threads you will see that installing Maple, MatLab, or Mathematica is non-trivial on OpenBSD. Could you tell me at least what kind of movies are you trying to embed into your slides?

Yes it is easier to learn than the Beamer but if know Beamer and it works for you maybe you should stick to your guns. This is the link to documentation and the source file for powerdot http://texcatalogue.sarovar.org/entries/powerdot.html I want to reiterate that is very easy to customize slides unlike Beamer although you can see in the documentation that the package comes with about 20 different layouts and many more different color patterns. Trying to install manually on the top of teTeX will probably fail due to the fact that teTeX uses some outdated fonts. I tired in the past. It is not worthy as TeXLive in current ports three is rock solid. 2. There were many questions about Movies. Yes, It is possible to embed movies into the slides.

As things stand at the moment on OpenBSD, your only real option is faithd which is a userland proxy that forwards a single TCP port between v6 and v4. PF does not handle nat-pt. You also need some tricks so that the v6 clients see an DNS record for the site they try to access: this is done with the totd port/package.

I've noticed that the command is getting cluttered with options to adjust the rules it creates to the needs of different pf configurations. it would be better to turn this on its head, and handle these in the anchor definition in pf.conf (i.e. define options which should be applied to all rules under that anchor: log, tag, queue, label, rtable, blah blah blah). Upon consideration, I at least partially agree with you (and note that 4.3 is moving in this direction) -- but some things can't be applied to all of the rules in the anchor. I haven't thought it through carefully enough to know whether this is a significant issue but, as a minor example, I like to specify the interface in each rule (possibly overkill for these particular rules, but I'd expect it to at least reduce the total number of rule comparisons) and that will certainly differ from rule to rule (since I have both a DMZ and an internal network). doing this in ftp-proxy(/tftp-proxy/ftpsesame/pptp-proxy/wherever else you might want it) would be an inefficient way of handling this and annoying to keep eveything in-sync. Is this really a problem in practice? I'd think it likely that, since all of these are parsing text into a structure suitable for using in an ioctl on the pf device, they could all use a common procedure to perform that action. (I haven't examined the code, so there could be something which prevents this; if you have examined it and know that there is such a problem, I'll defer to your greater knowledge.) Dave

I've noticed that the command is getting cluttered with options to adjust the rules it creates to the needs of different pf configurations. Has any thought been given to allowing arbitrary nat, rdr and pass rules to be specified in a configuration file (in the same syntax as for pf.conf) with macros defined for the server, client and proxy addresses (as in the examples; also, perhaps, a few other macros -- such as for the interfaces through which the client and server are reachable)? I'm not asking (let alone demanding) that anyone implement this, but would like to know if it's been considered and rejected for some reason, is on someone's to-do list, has never been thought about, or whatever. It seems to me to be a good way both to avoid needing more and more options to tweak the generated rules and to avoid the delay involved in modifying the program whenever someone comes up with a new need. Now that the 'tag' option is available I don't expect ftp-proxy to gain any more options wrt. to the pf rules it creates, because you can implement those yourself using 'tagged'. Only if exactly the same thing should be done for all rules in the anchor, since only one tag can be specified. I can't think offhand of any cases where this makes an important difference, but how sure can we be that there are none? The history behind the current implementation is that I wanted it to be simple. Having a configuration file with pf rules means that you either have: - embed a full parser, which is a lot of code - run pfctl, which makes it harder to chroot Or tweak the existing code in pfctl so it could be used (perhaps as a library routine) from ftp-proxy and anyplace else that wanted to make similar use of anchors. (I haven't examined the pfctl code, so I realize that this might turn out to be impractical.) Also, the FTP protocol is complex. Having the nat and rdr rules under user control would easily break things. Certainly true, for those who use the flexibility. So it would be a lot of extra code for not much gain. If using the code from pfctl is practical it shouldn't be all that much extra code, and the amount of gain depends on whether someone comes up with a real need for this sort of flexibility (I don't have anything specific to propose at this time). But I might well have made the same decision you did if it had been mine to make. Thanks for the discussion, Dave -- Dave Anderson [EMAIL PROTECTED]

Thanks, Ed If I remember correctly, you need to have the x-base package installed for the libiconv / gettext dependencies to be met. It's an issue with 4.2.

And that this list has a virtualization does not enhance security mantra? Just checking. If you want to experiment with a real network without having a large amount of hardware, what you're doing is actually a pretty good way of going about it. Just don't try to *actually* run it in production. That is pretty much what im trying to do, simulate a real network. Part of that being that all my virtuals would see themselves on the same layer2 network and would be able to talk to each other with out the host acting as a router, same way vmware does it. My goal is to have all the guests on internal addresses and use the host to nat them to publics as needed, as well as the host providing ipsec tunnels to allow other locations to access the client services via internal address. My question is: Is it best to put my private gateway ip on the real ethernet interface or on a loopback or other interface on the host? I'm not really sure what you mean. Most qemu setups I've seen connect to the host OS via tunX, so there is not really a private gateway there. You could NAT your real external interface into these tun devices. Joachim And part of a real network is that i would have a gateway(firewall). I misunderstood how qemu handle networking, i was under the impression that it piggy backed on a real interface, much the way that vmware or windows virtual machine does, you tell it attach to x interface and it puts a second mac on the interface and then uses that interface(all though shared) as if it was its own physical nic. Your reply suggests i am understanding it wrong, however i did not see anything in the man page saying otherwise, perhaps i missed something -- TFMotD: ul (1) - do underlining -- -Lawrence -Student ID 1028219

Kernel doesn't reclaim unused interface indexes?
OpenBSD's currently limited to using interfaces with an index 32 for multicast, and on one of my machines I created and destroyed enough virtual interfaces during experimentation that some of the interfaces currently in use and that I would like to route multicast traffic to have indexes = 32. The simple solution is to reboot since I have fewer than 32 interfaces total, they'll renumber and everything will be fine. However, I saw if_attachsetup (in net/if.c) there's some code for looping through ifindex2ifnet twice to try to find an unused interface index, so I figured I could avoid rebooting by creating and destroying ~65000 virtual devices to wrap the counter, and then recreating the necessary interfaces so I could use them in multicast. Fortunately, I tested this idea first, because it actually leads to a kernel panic. :-) A second somewhat closer look at the kernel's interface handling code gives me the impression that the ifnet structures are never freed, the ifindex2ifnet table is never zero'd out, and so that loop always results in a panic. Looking at the history on net/if.c, I see a commit comment from itojun that ifindex2ifnet could become NULL when interface gets destroyed, when we introduce dynamically-created interfaces, but this was four years ago and if_vlan has existed for 7 (though seemingly in a different form then). What does dynamically-created mean if not something like vlan/gif/carp/trunk? Is there anything major preventing ifindex2ifnet being cleared? (If it's just developer interest, it *looks* like it should be a straight-forward-enough fix that I'd be interested in trying to write a patch.)
