Re: Linux and Novell article in Linux Journal
Admirable sentiment. However, problem is with the methods, which are in the US governed by software patents. Don't get that confused with copyright which governs distribution. In the case of the software patents, it doesn't matter how the code is made or even if the code is visisble, only what the resulting software does or how it is used. e.g. encrypted harddrives, xml-serialization, web shopping carts, breakpoints, verb conjugation, firewalls, etc. The code could well originate completely independently, but if it *does* something covered by software patents or is *used for* something covered by software patents, then in the US and its subsidiaries you are SOL unless you have a few million on hand and a few months of staff time to spend in court. If we're going to tease or feel smug, let's at least do so for the right reasons. ;) In this case, OpenBSD is actually no more or less vulnerable than any other closed or open source software. That will be the case until the US brings some sensible aspects back to patent law, such as Europe has for the time being. Unfortunately, the current regime (I say junta) has been piggybacking them to trade agreements. Solution?

Re: No Blob without Puffy

It harms more than just the campaign, it harms anyone wanting to maintain a modicum of options further down the road in regards to hardware lifecycles, operating system and kernel lifecycles, and last but not least security. One anecdote regarding insecurity of mysterious binaries / BLOBs: A local privilege escation has been known to exist, unfixed, for several years in nvidia's binary drivers: http://lwn.net/Articles/204541/ However, if you can't audit (and subsequently compile) all the code, including the applications, libraries, compilers and OS, then you've got nothing secure and nothing that can be made secure - regardless of anecdotes, no amount of assurances, claims, hand waving, shouting, smoke, noise etc. from vendors. Don't take my word for it, read what the ACM had to say about it: http://www.acm.org/classics/sep95/ But it's not just 'security' that is at risk. The lifecycle of both the operating system/kernel and the hardware that rely on the continued availability of the BLOBs become dependent on the BLOBs producers. Those are groups which may or may not continue to have interests and motivations which overlap yours. If your hardware or system needs a BLOB to run, then the BLOB-maker has you on a leash. Endorsing BLOBs puts *all* hardware, systems, and security at risk through active effort, which is reprehensible. To have one system accepting them, makes it all that much harder to keep them off. Think digital scab. Tolerating BLOBs or failing to eliminate BLOBs, are simply balless passive means of putting the above at risk. To put it another way, it's possible to gain control (political, economical, technical) of systems that get locked into BLOBs either passively or actively and encroachment into one system/distro can be used to marginalize the others. So to put it as kindly as I can, only people somewhere on the spectrum between stupid and troll would be advocating acceptance or tolerance of BLOBs.

Yes. I want to run several separate instances of Debian under OpenBSD. I've started looking at sysjail and can look at qemu. Would there be any special reasons to choose qemu over others, besides that it's available in ports? -Lars Lars Nooden ([EMAIL PROTECTED]) On the Internet, nobody knows you're a dog ... ... until you start barking.

Mounting ext2 in a loopback device
How does OpenBSD handle mounting ext2 filesystems? What's wrong or missing from the attempt below? $ sudo vnconfig svnd0 debian.img $ sudo vnconfig -l vnd0: covering debian.dmg on wd0h, inode 41670 vnd1: not in use vnd2: not in use vnd3: not in use $ mkdir debian $ sudo mount -t ext2 /dev/svnd0c debian mount: no mount helper program found for ext2: No such file or directory Lars NoodC)n ([EMAIL PROTECTED]) Ensure access to your data now and in the future http://opendocumentfellowship.org/about_us/contribute

It's useful, but neither ch 9 nor ch 14 explicitly show an OpenBSD analog to this from the other system: sudo mount -o loop debian.dmg debdir; How is the debian.img formatted ? Ext3. Here is the exact sequence. Only the last line, which provides the content, is important as I am trying to migrate a few things to sysjail. dd if=/dev/zero of=debian.dmg bs=512k count=500; # mkfs.ext3 debian.dmg; mkdir debdir; sudo mount -o loop debian.dmg debdir; sudo debootstrap etch debdir http://ftp.de.debian.org/debian/; Was it originally partitioned ? No. I am all thumbs with fdisk. (Can follow recipes, though) How essential is partitioning in this case? For my part, it's probably not so important how or where the disk image is made, only that I would prefer a disk image that can be mounted and used on OpenBSD, Debian || Ubuntu and OS X. It is, however, intended primarily for use in sysjail on OpenBSD. Note that the linux partitions (stored in MBR and so on) are different from the OpenBSD partitions (stored in a disklabel, see the manpage to the program of the same name) [snip] Regards, -Lars PS. disklabel and fdisk output below disklabel svnd0 # /dev/rsvnd0c: type: SCSI disk: vnd device label: fictitious flags: bytes/sector: 512 sectors/track: 100 tracks/cylinder: 1 sectors/cylinder: 100 cylinders: 5120 total sectors: 512000 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # microseconds track-to-track seek: 0 # microseconds drivedata: 0 16 partitions: # sizeoffset fstype [fsize bsize cpg] c:512000 0 unused 0 0 # Cyl 0 - 5119 disk svnd0 fdisk: sysctl(machdep.bios.diskinfo): Device not configured Disk: svnd0 geometry: 5120/1/100 [512000 Sectors] Offset: 0 Signature: 0x0 Starting Ending LBA Info: #: idC H S -C H S [ start: size ] 0: 000 0 0 -0 0 0 [ 0: 0 ] unused 1: 000 0 0 -0 0 0 [ 0: 0 ] unused 2: 000 0 0 -0 0 0 [ 0: 0 ] unused 3: 000 0 0 -0 0 0 [ 0: 0 ] unused Lars NoodC)n ([EMAIL PROTECTED]) Ensure access to your data now and in the future http://opendocumentfellowship.org/about_us/contribute

jails in openbsd
I'd like to look at some virtualization options for openbsd. The ultimate goal would be to get several isolated Debian systems running inside some kind of enironment for virtualization. Can you point me to an openbsd package, port or source code for the freebsd jail or an equivalent? -Lars Lars Noodin ([EMAIL PROTECTED]) Ensure access to your data now and in the future http://opendocumentfellowship.org/about_us/contribute
