Re: Opening VPN ports

I would like to enable a VPN connection through the firewall into a Win2K3 server that sits behind the firewall. I am finding conflicting information on what ports/protocol to open up. Microsoft is saying protocol ID 47 and TCP port 1723 both inbound and outbound. If that's true, then something like the following should work: pass in quick on ext_if proto 47 from any to any pass out quick on ext_if proto 47 from any to any pass in quick on ext_if proto tcp from any to any port 1723 keep state pass out quick on ext_if proto tcp from any to any port 1723 keep state I had not luck with the above. If I disable PF I can connect fine, so I know for sure that the problem has to do with PF blocking my access. To complicate matters, I've found other references to protocols 50 51 and port 500. I'm hoping that one of you who has this working can let me know what I need to config in order to allow my VPN connection to pass through the firewall. add 'log' statement to your block rule, than tcpdump -n -e -ttt -i pflog0 to see which packets are being droped and by which rule, example (from 4.2 tho): Mar 18 07:39:26.412253 rule 8/(match) block out on fxp0: 192.168.1.2.42731 192.168.1.98.6335: [|tcp] (DF) [tos 0x10] you see the packet is blocked on it's way out of fxp0. -- error: one bad user found in front of screen

pf label and viewing with tcpdump?

Re: Flexibility of pf rules created by ftp-proxy?
Dave Anderson wrote: I've been working on the pf configuration for my home firewall, including setting up ftp-proxy. 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'. 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 Also, the FTP protocol is complex. Having the nat and rdr rules under user control would easily break things. So it would be a lot of extra code for not much gain. -- Cam

glxpcib: tiny bug fix
Without the fix below, reading back the state of the impulse switch
(GPIO24) on my ALIX always returned '0' (e.g. switch is pressed). Now it
returns '1' if depressed, and '0' only while pressing it, as expected.
As AMD5536_GPIO_READ_BACK was already #defined but so far unused, I
assume it was just a small oversight which crept through testing while
reading back the LEDs' state only. See p. 480ff in the CS4436 Companion
Data Book for a detailed description of the registers in question.
Note: This fix changes the values returned while reading the LEDs' state
(GPIO6, 25 and 27). Before, they alway reflected the last state written
(LED on or off). Now, they always return '0', unless you set 'in' flag,
upon which it returns always '1'.
The LEDs' current state can't be read back anymore this manner because
these GPIOs do not support the 'inout' flag.

relayd layer 7 http proxy and filtering questions
We are looking to do some URL path and request method filtering with relayd if possible. Many of the other layer 7 filters like User-Agent and Referer work without issue. The box is built using relayd from -current cvs downloaded on Mar 18, 2008. Relayd is setup to be a reverse HTTP proxy with layer 7 filtering as a relay to a test webserver. Similar to a firewall mindset, we are looking to block everything other than what we specifically list out. 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. The following is from our test relayd.conf file, but these rules block all access. Is there a way to list out each file type, one per line? Can we instead use something similar to a regular expression like, request path expect (^\/|\.html|\.jpg)$ ## ## URL filtering (NOT working yet) label BAD path request request path expect / request path expect /*.html request path expect /*.jpg The second question is how to only accept the GET and HEAD request methods and deny any others. For example we do not want the webserver to ever see POST or TRACE methods. As GET and HEAD are not headers, we are unsure as what rules to use. ## ## Block bad request method (NOT working yet) label BAD request method request header expect GET request header expect HEAD Since it is a work in progress, our full relayd.conf file can be found here for reference: Relayd proxy how to (relayd.conf) http://calomel.org/relayd.html -- Calomel @ http://calomel.org Open Source Research and Reference

What I mean is that when using full screen (with xpdf or kpdf etc) it takes some 3-4 seconds to change a slide. I don't know why... I can provide you with a test talk, so that you udnerstand what I mean. This is very bad when somebody in the public asks a question of plot number 2 in slide #3 and you're in slide #55. Sure there are ways to overcome the problem, with the progress bar of latex-beamer, for instance, but still I don't like it. I just want to ask here in misc whether somebody has had the same problem and what other alternatives there are. I have noticed that a lot of people are using magicpoint out there. I had a look at it, but it seems not obvious to use when it comes to latex.

PF puzzlements.
I've got The Book of PF on order. Meanwhile I will continue to fumble through on my own. I work at a boarding school. Freetime Internet access is a carrot we use to encourage accademic performance. Most free time use is java games and social networking sites. I am trying to set up a system to allow internet usage on a per person basis. I work in a school, and the kids aren't terribly shy about loaning/borrowing accounts. (I've already set up my windows boxes so that if the same user is detected logged in on more than one machine, then BOTH machines reboot. Sometimes it's because a kid forgot to log off. Sometimes it's because he logged in for someone else.) I want to change the system from one where computer access is allowed/denied (script working on smbpasswd file.) to one where internet access is allowed/denied through pfauth. The firewall box also runs squid in transparent mode. Almost all of the internet access is for the web. I want to use pfauth instead of squid's authentication for several reasons. 1. To use squid's authorization I have to make squid non-transparent. 2. I have a prototype authentication scheme that will work with ssh/pfauth, but that is beyond me for squid integration. (Notion is to build up a set of questions/answers that only the user will know. In essence a bunch of questions for each user on the line of what is the middle name of the first girl you had a crush on? with them having considerable leeway in which questions they want in their personal security database) 3. I want to regulate the non-squid access too. How do I set up pfauth to authenticate both squid and network trafic? How do I set up tallying by user so that I can get an idea of who's spending too much time on facebook.

I can provide you with a test talk, so that you udnerstand what I mean. I'm using latex+beamer noadays too. The behaviour you describe is generally caused by slides with lots of bitmapped images in them that need to be rendered/scaled before displayng them. If you have images that get repeated on each slide, like a logo, a background image or some other theme elements, you can reduce both the PDF file and the time it takes to render each slide by using the pgf package and \pgfdeclareimage/\pgfuseimage. Use images that have a resolution that more or less matches the resolution at which they will be displayed. Scaling downa 3000x2000 image to 320x200 every time it's displayed takes some time. Also make sure pdflatex is correctly configured to use Type1 fonts and not bit-mapped fonts (it can be tricky if you use an input or font character encoding other than TeX's default, but texlive makes things easier).

If it's using the integrated LX800 graphics for its display, OpenBSD will not run X on it. The amd/geode X driver needs some kernel support that's currently more or less Linux only. (Shouldn't be too hard to add to OpenBSD though, but none of the developers has access to this kind of hardware and enough motivation to do it).

I use the 'seminar' latex package, together with the cumulative overlays in postscript trick from section 12.2 of the seminar package FAQ, http://www.tug.org/applications/Seminar/Seminar-FAQ.html . I find that the speed, or lack thereof, which which xpdf renders each new page (or progessive-overlay-on-the-same-page) varies from too fast for any perceptable delay to a couple of seconds and sometimes even to 10 secondes. It seems to depend entirely on how big/complex the graphics are that I include -- if a page has only text and/or latex math, it renders instantly. But if there are big/complex graphics, then it can be slower. (The 10 seconds is only for some really nasty graphics files.) It's never occured to me that there was anything I could do about this other than enabling 'apm -H' when I give the talk. I could imagine a fancy viewer pre-rendering in the background while previous pages are being displayed, but absent a lot of caching (= potentially big memory usage) that scenario would still fall down in Pau's case where [[...]] somebody in the public asks a question of plot number 2 in slide #3 and you're in slide #55. -- -- Jonathan Thornburg [EMAIL PROTECTED] School of Mathematics, U of Southampton, England C++ is to programming as sex is to reproduction.

Disk I/O problems
Hi, I am having an issue with running OpenBSD on a Sunfire V40z. The server run AMD dual core processors. I have tried a number of different versions of OpenBSD and they all seem to have the same issues. One of the builds I did fluked and it's working as expected but I have not been able to duplicate it. I have checked the bios settings and versions. I have matched the settings and versions of the firmware on the SCSI disk controller. The hardware is the same. Below is a bunch of data. I need to be able to build consistance servers. Please help. The test: To test I am using a tar ball that is 60.9M in size with 167,000 files in it.

To speedup the display, i converted the whole presentation to pnm images (one image per slide) and then made my presentation using graphics/qiv port. 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

Re: using openbsd to make presentations
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.

I just want to ask here in misc whether somebody has had the same problem and what other alternatives there are. I have noticed that a lot of people are using magicpoint out there.

I run into a snag in a number of occasions. 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)? I am a mathematician so I am quite often in the same position as you to give presentations which contain lots of formulas and images. I use Powerdot class of Latex presentations (descendant of Prosper an obsolete class of presentations ) which is as an alternative to the Beamer class. For the comprehensive review of all classes of presentations for latex you may check http://texcatalogue.sarovar.org/bytopic.html#present The advantages over Powerdot over Beamer are numerous. Powerdot is far easier (has only 60 man pages v.s. Beamer man pages are over 400 pages). It is also very simple to incorporate movies into your slides. The slides are easily customized and in my point of view far more beautiful than the Beamer. The popularity of Beamer seems comes from the fact that you can use pdflatex to produce pdf slides. That is not possible with Powerdot as it uses some PostScript tricks. So you will have to latex slides followed by dvips and ps2pdf or dvipdfm to produce pdf slides. The ultimate goal of course is to produce pdf slides. I noticed that one has to use Adobe Reader (I prefer Xpdf as well) which is only available from ports due to the license issues in order to have alive links on slides. That seems to be built in feature ( I would call it bug) which should be communicated probably up stream. The slides are very responsive. I personally have not seen better looking slides on any platform and I think I have seen it all. Powerdot class of presentations is part of TeXLive but not the part of teTeX. 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 1Gb but includes all TeX/Latex features coded at the moment. I am not sure if the TeXLive base includes Powerdot. I would guess yes. Most Kind Regards, Predrag Punosevac Thanks, Pau

Running old hardware is a hobby not something you should depend on, one $700 dell server can replace dozens of crappy 5 year old machines using a tiny fraction of the power and generating a fraction of the heat. Of course its not as much fun hunting for spare parts in the trash or on ebay but you will have more time to get real work done.
