Re: pf state limits
* Brian A.

I have a couple Wild guess: The limitiation is the max value that the variable size of the counter can contain, followed secondly by physical memory. no, it is much much more complicated than that. If there was an easy, reliable way to calculate the max, we would have the kernel do the math and not export a user-settable limit. there is no better answer than try out. increase, fill state table. repeat until the box panics. than chose a limit smaller than that. -- Henning Brauer, [EMAIL PROTECTED], [EMAIL PROTECTED] BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting - Hamburg Amsterdam

Tracking stable procedure
As I am still a fairly new to OpenBSD in a production environment, I have written a few procedures for myself to follow so that I can do some of the day to day tasks without screwing them up. This is my procedure for tracking stable. If any of you see any errors, please call me an idiot and point them out. Note, I have read the faq (again and again) as well as a couple of books and a number of articles. Unfortunately, it seems like there are as many variations on tracking stable as there is articles etc about tracking stable and my poor mind has some trouble figuring out which is best. So here is mine: Get the Source Code: # export [EMAIL PROTECTED]:/cvs # cd /usr # cvs checkout P rOPENBSD_#_# src # cvs checkout P rOPENBSD_#_# ports Compile and Install the Stable Kernel: # cd /usr/src/sys/arch/i386/conf # config GENERIC # cd ../compile/GENERIC # make depend make (this will take a while) # cp /bsd /bsd.old # cp bsd / # shutdown r now Compile New System Binaries: # cd /usr/src # rm r /usr/obj/* # make obj make build (again, this will take a while) Stuart van Zee [EMAIL PROTECTED]
pf default queue inspection
Hi All,
I've got a firewall with several dozen pf queues on, and all has
been working fine for past few years, however I've managed to somehow
at some point end up with a bunch of traffic end up in the 'default
queue'. My intention is that every packet should end up in a defined
queue (as we use this for accounting etc). Anyone think of any ways
I can work out what packets are ending up in the default queue? As
the default queue is where packets which don't match a rule end up, I
can't add a log statement or anything. I've tried putting in:
# Default outputs -- these should probably go at some point
pass out log on $ext_if proto tcp all keep state flags S/SA queue d3
pass out log on $ext_if inet all flags S/SA keep state queue d3
pass out log on $ext_if proto { gre, egp } all keep state queue d3
before any of my real queues to hopefully get everything that doesn't
match into the queue d3 and then I can view what is going on with
tcpdump and pflog, but I still seem to be missing something.
Any ideas?
-Matt

Re: flowcharts
[EMAIL PROTECTED] asked: Do any of you use flowcharting software, and if so what do you use? I am just beginning to explore the world of programming and have so far used Microsoft (spit) Visio. I tried both Kivio and Dia but they fall short for me. My code choices are (due to the course I am attending) limited to JavaScript and pseudocode. By all means experiment with flowcharts, but be prepared to move on: I haven't used flowcharts in nearly 30 years, and there are good reasons. First, they teach you nothing about good structure - it's too easy to draw spaghetti. Second, they're never maintained - code gets tweaked, but the (graphical) flowcharts don't - so they become misleading documentation. Lastly, if your code is so complex that it needs a flowchart to be comprehensible, you're doing something wrong - or, at least, there are better ways. My suggestion would be to flowchart in pseudocode (avoiding the infamous goto, of course - haven't used those in 30 years, either - there's always a better, cleaner way). If you have large, complex indents, consider decomposing further: turn the indented section into a function (with a simple, clean name and interface - think generality). Think in terms of vertical complexity rather than horizontal. Aim to make your code as readable as you can. Similarly, make the code self-documenting: if maintenance relies on separate documents, it'll become harder when the docs fall behind - as they invariably will. All IMHO, of course, but learned the hard way ;). And it is entirely possible that this is something you *have* to learn the hard way, hence my opening words.

Re: Sun Netra X1 Firewall Throughput?
Bryan Vyhmeister wrote: One thing I was wondering about the X1. Does it support hard drives larger than 137 GB or whatever that old limit was? I don't know if Sun systems are affected by those same kind of issues as older PC stuff but I don't want to get bitten by that one if they are. No it doesn't. I have about 30 of them and putting any drives bigger then that will simply not work. Well, actually it work, but you can't use above that. If you try to even partition it like that, the system will crash and not start, period. I try a good Seagate 180MB for test and can't use it all.

I am considering using a pair for a theoretical maximum throughput of about 45 Mbps. Can the Netra X1 comfortably handle this with carp(4) and some pf firewalling. I know this is pretty generic but any comments? (In case you are wondering, I would run pfsync on a VLAN on the less used interface.) Thank you. The X1 is great for firewall. Your limits to consider is not the transfer in Mbps, but always the PPS. That's where you will hit the wall if to high and that's not only with X1, but any servers. PPS is really the biggest problem here, unless you start talking multiple time 100Mb/sec.

Logging by originating host, and much more, is available in syslog-ng, available from the ports tree (/usr/ports/sysutils/syslog-ng). It can be a little tricky to get syslog-ng to co-exist with the stock syslogd, or to entirely replace it with syslog-ng. Kevin

Timothy I think the point is that if someone roots your machine because you are running a vulnerable service, they can't really install rootkits and things if your binaries are on a filesystem that CAN'T be remounted r/w. If you just mount your harddisks (or portions like /etc) ro and someone roots your box, they just re-mount it, install rootkit, then re-mount back ro. Does nothing really.

We need to have an https server running that users can upload un-encrypted files to and have those files encrypted on the fly and safely stored away until they are needed. Sounds like a simple Ruby/Python/Perl/Python script to handle the upload, saving as a temporary file until the upload is complete, then encrypting. Might be a tad tricky to ensure the upload is complete first, but should not be a big problem. Those same people will need to be able to download their files as they need them and have them decrypted for them and sent over https so that they can use their web browser to retrieve the files. Just the opposite for retrieval? HTH, Lee -- This officer's men seem to follow him merely out of idle curiosity. -- Sandhurst officer cadet evaluation.

US Export of Cryptography
After reviewing OpenBSD's current policies on US contributions of cryptography, and current US law, I'd like a clarification. Current US law (c.f. the short guide http://www.bis.doc.gov/encryption/lechart1.htm) allows the unlicensed export/reexport of open source encryption source code. The only restriction prevents knowledgeably exporting to one of the restricted countries. BUT, there is this gem stuck in the section: Note to paragraph (e). Posting encryption source code and corresponding object code on the Internet (e.g., FTP or World Wide Web site) where it may be downloaded by anyone neither establishes knowledge of a prohibited export or reexport for purposes of this paragraph, nor triggers any red flags necessitating the affirmative duty to inquire under the Know Your Customer guidance provided in Supplement No. 3 to part 732 of the EAR. Is this not an acceptable restriction? Basically, this means that no primary CVS servers used by US crypto devs can be located in one of the restricted countries, nor can a US server push to such a country. As long as access is completely open, and the source code is pulled, this section makes it quite clear that everything is peachy. The only gotcha here is the notification requirement each time the encryption SW is updated. However, the requirement is just notification, not permission, and is submitted by email. It is not 100% clear, but a CVS commit email from the appropriate sections of the source tree would appear to satisfy this requirement. This would also only be required for contributions from US cryptographers. This was the result of a short look into the US laws, and obviously this isn't something that will just change overnight. But, I think it would be useful to start up a conversation about changing OpenBSD policies to allow US contributions. I'd be willing to conduct further, comprehensive, and more conclusive research if I were to receive reassurances that the restrictions above (or similar) are acceptable. Sources: http://www.access.gpo.gov/bis/ear/txt/740.txt Section 740.13 (e) P.S. Sorry if this isn't the right list. It's the most appropriate as far as I can tell. -- Mark Reitblatt
