Re: Max DMA size
Hmm. My knowledge may be a bit dated in this matter, but as I recall the 8237 DMA controller standard on PCs only supports DMA requests up to 128k (and then only on the upper 4 DMA channels). The low 4 DMA channels were byte-granular and could only transfer 64k. Am I correct in assuming from this discussion that the state of affairs is somewhat different nowadays? Uh, yeah. Standard PCI h/w usually has 32 bit dma engines, and a lot have 64 bit. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

FreeBSD bridging support places nodes in the same broadcast domain, but different collision domains. As such, you may see reordering of packets between segments, and packets may be lost transitting between segments. FreeBSD's bridging support is not 802.1d-compliant for a variety of reasons, and does not support spanning tree. That said, it is adequate for many uses, including our packet filtering support, which is very useful indeed :-). That said, we might do well to look at the OpenBSD bridging code and see if we can merge the behaviors -- they have some spiffy features (which I heard about at USENIX), including MAC-address based filtering, and some sort of VPN bridged technique (which sounds very useful).

NATD-Bug???
Hi all, I've configured my Server as a router, so when I'm online, I automatically start natd, to let my other computers use my server as a gateway. But thw problem is, that NATD dies after about 10 Minutes. The process is still there, but I can't route anymore. After flushing all rules and starting Natd again, it works. I route ed0 -- isp0. Is this a known problem? Any workarounds?? Thanks, Freddy To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

Its using more resources printing the message thsn the "stray interrupts" themselves. DB If you *have* an lpt controller and dont need the IRQ you could turn it on and enable the lpt driver in the kernel, that usually seems to take care of it on systems I had this message on. For this reason I usually leave lpt stuff enabled on systems even I'm unlikely to need the parallel port.. The other obvious alternative is to grep for it in the source and comment the printf.

Re: bridging
They can't be in the same collision domain -- the only way to do that is to have an Ethernet repeater which repeats bit by bit fron one segment to another, and propagating a collision on one segment as a jam on another. On a FreeBSD box, where you interfaces to ethernet segments are NIC cards, you can't get your hands on the ethernet frame until the NIC has received it completely. Thus, you don't have to opportunity to act as a repeater (not that you'd want to anyway) to have a single collision domain. louie On Fri, 7 Jul 2000, Narvi wrote: On Thu, 6 Jul 2000, Sean Lutner wrote: Bridges create a broadcast zone. broadcast packets will cross the bridge unobstructed.

Re: Code Pal VMS
Wait a minute guys, this might be a valid (although not very clearly stated) FreeBSD question. After a little digging around, it looks like PALcode is firmware on the DEC Alpha (for which there are versions of VMS, as well as FreeBSD). To the original poster: search for information about the FreeBSD port to the Alpha architecture at http://www.freebsd.org/ . Failing that, post your question to the freebsd-alpha mailing list with a few more details about the context of your question.

Module parameters?
Mike, A couple of months ago we spoke about my needing the ability to set module parameters during a kldload, and you indicated that you would be working on them for FreeBSD 4.1. I've since progressed my DSL driver to the point where it works in all the modes I need (same as the Linux driver), but I have to recompile my driver to change any options. Therefore, I haven't done any further work on it, and I have been unable to make it available to anyone else for beta testing (since everyone needs to change options for their particular installation)... I was wondering if you (or anyone on this list) has had time to add module parameters to kldload? (and before anyone suggests it, sorry, but I am barely able to squeeze out enough time to even work on this unofficial driver, I can't work on kldload) Thanks, Gary -- = Gary Corcoran - Distinguished Member of Technical Staff Lucent Microelectronics - Client Access Broadband Systems Communications Protocol Driver Development Group "We make the drivers that make communications work" Email: [EMAIL PROTECTED] = To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message

I have poked around other OS but have found them unappealing to my interest, I like the concept of free source systems like linux and have played with SUSE a little but found the limited availability of learning materials in english a hinderance. I have downloaded and printed the manual as of page 34 where I came upon your invitation I decided to reach out and touch someone. I woud like some quick advice as to what version I should install via ftp to begin my learning, and what would be the best path to follow. I am particularily interested in learning to program in an acceptable language and want to concentrate on network protocols and reliable secure communications, as well as network security and firewalls. Thank you for any advice that you can offer. My best advice for a complete novice would be to buy the book "The Complete FreeBSD", by Greg Lehey, install the version of FreeBSD on the CD-ROM found inside the book, and use the book as a guide to configuring FreeBSD for whatever you need. Once you've gotten that far, then come back and ask questions in the freebsd-hackers mailing list, you'll be ready for us by then. In the meantime, direct questions about how to configure various parts of FreeBSD to the freebsd-questions mailing list, you're much more likely to find willing helpful people there. It's our "support line." Best of luck, and let us know how you do. Better yet, once you've got FreeBSD running to your satisfaction, write an article about it for a magazine, a web site, or your local newspaper and tell us about it. ;^) -- "Where am I, and what am I doing in this handbasket?"

OpenSSH 2.X problem with escape chars?
Hey... just noticed something odd. I just upgrading one of my FBSD boxes to the latest -STABLE and modified /etc/ssh/sshd_config to use version 2 then 1 (Protocol 2,1). After doing this when I connect to that server the escape sequences (~^Z and friends (as per 'man 1 ssh')) no longer work. If I connect version 1 they do. If I connect version 2 they don't. Any thoughts? The client I'm connecting from is a 5.0-CURRENT (7/6/00) system. -Steve To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
