While I'm a subscriber to freebsd-questions, top posting, incomplete questions, inflammatory commentary, etc. is just the price I pay for getting a steady stream of "Aha's," and hardly seems worth the effort to develop an emotional viewpoint.

I'm not trying to stop anybody. I'm purposing ping for SMTP, The
construct is like an echo request. So when you send a blank message
with a subject such as test or ping the mail server replies to the
email saying it got the email. The mail server that acknowledges this
email would be whatever was listed in the DNS MX record of the email
address that was entered in the to: field. So if I ping the email
address [EMAIL PROTECTED] then {mx1,mx2}.freebsd.org replies back
to say it got the message. I think this could be a useful diagnostic
tool.

No the mail all goes to the same server. When you subscribe to the
group the mail server send you a confirmation email that you must
reply to and then it sends a welcome email.

First, I was just semi-jesting to the group in general, not singling
you out...
Second, I think it kind of goes against the spirit of simplicity to add
a form of "ping" to the SMTP protocol.
Third, while it may work in this particular case with this particular
setup, there are many variations of mailing lists and servers where
this might break...i.e., this setup, to me, sounds very
situation-specific. I.e., people who have servers that accept mail
before actually delivering it...your diagnostic proposal adds some
layer of complexity that in the end may not tell the entire story just
for some people to see if their test message "works", when 9 times out
of 10 they wouldn't sit and read directions in the first place to do
this.
Actually, fbsd_user is right; wouldn't sending tests only test if you
can send test messages to the test group while not at all verifying

No the mail all goes to the same server. When you subscribe to the
group the mail server send you a confirmation email that you must
reply to and then it sends a welcome email.
That alone should be enough to tell you that you're subscribed and
should be working.
What exactly is the poster trying to test? That messages appear in
their inbox on sending, that other people can read their message? In
those cases, your ping proposal wouldn't work. If they got to the
point where they confirm joining, that tells you it should all be
working. The "test" message is more like a tentative "anybody out
there?" message...which could be better served, in my opinion, by
actually sending a question or sitting back to see when a message comes
in from other people to your inbox.
I think the more intelligent approach to "test" the connection would
be
to actually send some kind of question a new user would have about
FreeBSD to the list as a sly way of testing the configuration, but
that's just me.
What about this?
Um...sure...what about what about it? (your reply here means...what
are you trying to say here?)
Happy holidays to anyone on the list who happens to have a holiday
coming up, by the way... :-)

Re: Hard drive stress test
>> > Could somebody please recommend a utility or script suitable for > stressing a hard disk to check for possible errors? >> You might look in your hard disk manufacturer's web site for testing and diagnostic software. For example, Maxtor has something called "Maxblast" and Seagate has "SeaTools". I don't find these programs very useful for uncovering and fixing surface defects. You might as well just try dd'ing your hard drive into /dev/null. I have a program that began life twenty+ years ago as a hack for finding bad sectors on SMD disk drives so they could be mapped out. It worked quite well for that and also had the very useful (annoying?) habit of uncovering controller/data-path problems (that one bit in a zillion that got flipped for no good reason). I recently dusted this program off and hacked it to automagically determine on FreeBSD the size of the special file (disk,slice,partition) that it tests and to avoid the effects of disk caching in the kernel and the drive. I could give you a copy of the program, but I must warn you that there is virtually no external documentation and that it seems ineffective on modern SCSI/ATA disk drives. I don't know about ATA drives, but virtually all SCSI drives come configured to hide their mistakes. There is a bit, called "PER", in a SCSI disk drive "error recovery" mode parameter page one can set to enable the reporting of soft errors, but I don't trust it because during the thousands of hours I have worked over SCSI disk drives I have yet to see a single soft error reported. I can't explain it. I don't believe even modern disk systems are that reliable. Possibly SCSI host adapter drivers don't like to report soft errors either (seems unlikely). Another problem is what to do with a bad spot once you find one. I don't think I ever wrote any code to map out flaws on SCSI drives. Perhaps it was not necessary. Most SCSI drives have another bit, called "ARRE", in their "error recovery" mode parameter pages that enabled automatic "reallocation" of sectors on read errors. Unfortunately, I have never seen this work either, perhaps because sectors cannot be automatically reallocated after hard errors (because the data with which to initialize the mapped sector is not available). You might as well forget about testing/diagnostics programs. These things just don't seem to work anymore and the hardware manufacturers don't seem to have much interest in producing them, perhaps because the primary effect of such software is to increase the number of requests for technical assistance and warranty repairs. You don't want to know. Just cross your fingers and pray.

Try a sensible blocksize. 16k would mimic a standard file system block, but even that is likely to underestimate. If you were, say, copying the disk to another you could easily use 1Mb.

So when I logged into the system via ssh and ran the test I did not know that the array (RAID5, 8 disks, SATAII, PCI-X) was operating in degraded mode. Having run extensive iozone testing on this array when I first designed it I just assumed diskinfo was lying when it said I was getting 70MB/s transfers, I was getting sustained read transfer rates of 105MB/s on a 650GB test file back when it only had 4 drives. This is the reason I said diskinfo was useless, however, I still feel that diskinfo is sorta useless because it only shows you the tip of the iceberg. A tool such as iozone is much more useful for getting accurate numbers for the entire disk subsystem. Do you know how disk caching effects your system? Do you know what FreeBSD, and it's tunable setting, can do to your file system? Best stripe and block size for your needs? iozone can tell you all of this and more. Remember that 105MB/s number I quoted above?, that's just the sustained read transfer rate for a big ass file, I don't need to work with big ass files. I need to work with 15MB files (+/- 5MB). After buying the right disks, controller, mainboard etc. and lots of tuning with the help of iozone I get: 200 - 350MB/s overall (read, write, etc.) for files less then or equal to 64MB*. So anyways, that's what iozone can do for you. google it and you'll find out more stuff about it. *in a 4 disk setup running FreeBSD 5.4, I have 8 disks today and run FreeBSD 6.1-PRERELEASE. so those numbers went up because I have 4 more disks and the file system speed improvements to the FreeBSD 6.x line, but I have not benchmarked the improvements because the server is in production now. -- BSD Podcasts @ http://bsdtalk.blogspot.com/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Their are two primary reasons I can get such high transfer rates from simple SATA drives. The first one was the selection of the mainboard that had a PCI-X slots, I built this system before PCI-Express mainboards and controllers hit the market. The PCI bus is severely restricted and obsolete, I'm simply going to post the theoretical maximum throughput in MB/s for the various bus standards: f(x,y) = x-bits * y-MHz / 8 = maximum theoretical throughput in MB/s PCI: 32 bits * 33 Mhz / 8 = 132 MB/s (standard PCI bus found on every pc) PCI: (32bits, 66MHz) = 264MB/s (Cards are commonplace, mainboards aren't) PCI-X: (64, 33) = 264MB/s (obsolete, won't find it on new boards.) PCI-X: (64, 66) = 528MB/s (Commonplace.) PCI-X: (64, 100) = 800 PCI-X: (64, 133) = 1064 (Commonplace.) PCI-X: (64, 266) = 2128 PCI-X: (64, 533) = 4264 (very hard to find, even on high-end equipment.) PCI-X version 1 (66MHz - 133MHz) and PCI-X version 2 (266MHz - 533MHz). PCI-X is backwards compatible with PCI and slower versions of PCI-X, for example you can put a standard PCI card in a PCI-X 533MHz slot and it will simply run at (32, 33) similarly a 66 MHz PCI card will run at (32, 66) and so on and so forth. PCI-X is also forwards compatible in the fact that you can run a 133MHz PCI-X card in a standard (32, 33) PCI slot. Because of the backwards and an forwards compatibly I feel that PCI-X is superior to PCI-Express, *BUT* PCI-Express moving forwards is far far superior to PCI & PCI-X because it does not have 13 years of legacy to remain compatible with, it's cheaper to produce, and it's already in lower-end desktop systems as a replacement for AGP thanks to all the gamers. A few years from now PCI will end up where ISA / EISA are. I'm veering way off topic so I will not go into anymore details about PCI, PCI-X, and PCI-Express. Google around for the shortcomings of PCI / PCI-X and why PCI-Express is the future. PCI-Express: PCIe is not compatible with PCI or PCI-X (except for PCIe to PCI bridging) and it's just, well, totally different from the PCI spec and I'm already way off topic so again just google the details. It's theoretical maximums are expressed in Gigabits per second but I will convert them to MB/s for comparison with PCI and PCI-X. x1: 2.5Gbps = 312.5MB/s x2: 625MB/s x4: 1250MB/s x8: 2500MB/s x12: 3750MB/s x16: 5000MB/s x32: 1MB/s Anyways back on topic, what was the topic? Oh yes, why you won't see 200MB/s - 350MB/s if your using a standard PCI slot. If you look back up all the way at the top you will see that the standard PCI bus is a crap shoot and that it's limited to a theoretical maximum of 132 MB/s. What this means is that your RAID controller and the disks attached to it and the cache buffers attached to the disks are all capped at that theoretical maximum of 132MB/s. Then you have to take into account that the PCI bus is shared with other devices such as the network card, video card, USB, etc. Your RAID controller has to fight will all these devices and a 1Gbit NIC card can eat up 125MB/s (12.5MB/s for a 100Mbit NIC). The next reason for those high gains is because I picked drives with 16MB cache buffers and that I'm insane enough to run a production server with the write-back cache policy enabled on the array controller and enabling the write cache on the disks. This is stupidly insane unless you've planned for the worsts. The worst case scenario would be that you corrupt the array into an unrepairable state and loose everything if you had a power failure. -- BSD Podcasts @ http://bsdtalk.blogspot.com/ __

If you look back up all the way at the top you will see that the standard PCI bus is a crap shoot and that it's limited to a theoretical maximum of 132 MB/s. What this means is that your RAID controller and the disks attached to it and the cache buffers attached to the disks are all capped at that theoretical maximum of 132MB/s. Then you have to take into account that the PCI bus is shared with other devices such as the network card, video card, USB, etc. Your RAID controller has to fight will all these devices and a 1Gbit NIC card can eat up 125MB/s (12.5MB/s for a 100Mbit NIC). The next reason for those high gains is because I picked drives with 16MB cache buffers and that I'm insane enough to run a production server with the write-back cache policy enabled on the array controller and enabling the write cache on the disks. This is stupidly insane unless you've planned for the worsts. The worst case scenario would be that you corrupt the array into an unrepairable state and loose everything if you had a power failure. -- BSD Podcasts @ http://bsdtalk.blogspot.com/ __

Resolving Perl 'make test' Errors?
We're running perl 5.8.7_2 (from ports), with a mix of modules installed via ports and CPAN, all on a 6.0-STABLE machine. Someone tried to install WWW::Mechanize from CPAN, and when it tried to do a 'make test', there was an error. If I build the module in ports and go into the work directory and run 'make test' manually, I get the same test error. I usually prefer to install Perl modules through ports when possible, so that portupgrade can take care of them for me. However, one of the shortcomings of the (at least default) way in which ports installs Perl modules is that ports does not run 'make test'. Is there a clever way to have the ports system run 'make test' before installing a Perl module? Most of the /usr/ports/*/p5-*/Makefile files do not have 'test' defined as a target. Does anyone have any advice for how to go about ironing out this problem? My first inclination is to remake each of my p5-* ports and run 'make test' on them manually and then have CPAN reinstall everything that we have installed via CPAN.

How to test if online?
Hi all, I am using a FreeBSD box as an DSL router. Sometimes the inet connection does down and ppp is unable to reconnect. I want to detect via a cron script if I am online and if not reinitilize the connection. The script works ok when run manually, but when executed from cron it sometimes reinitializes the connection even when it is not neccessary. Now my question would be how I could improve the script, or if there is a better way. As you can see from the script I am not really a programmer, but I tried what I could. #!/bin/sh if !(/sbin/ping -c 1 freebsd.org) then /usr/bin/killall ppp /bin/sleep 1 /sbin/ifconfig xl1 down /sbin/ifconfig xl1 up /bin/sleep 1 /usr/sbin/ppp -quiet -ddial -nat tdsl fi - thanks in advance Christian Tischler ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

You can use ftp or fetch from the base system to test downloads of some reasonably large files, and get a decent estimate of your bandwidth (or that of the server, depending on which is lower). However, the network-based tests from your ISP, speedtest.net, dslreports.com, etc including the tweak test often provide useful information about MTU, dropped packets, tweaking TCP window size, etc, so a browser-based test is a good approach.

squid hello write test failed
Dear All This is a amd64 box with FreeBSD 6.3. So far it is only acting as a firewall (with PF). Yesterday I installed squid via ports with a pretty vanilla configuration. I.e. no neighbour caches, just to be used as a standalone cache for users from the inside net. No interception caching (yet). Squid was not yet put under heavy load - in fact I am so far the only person using it. Everything worked fine yesterday. However, squid "died" after "squid -k rotate" was executed by cron over night. Here is what it came up with after (successful) log rotation: 2008/04/23 04:20:00| storeDirWriteCleanLogs: Starting... 2008/04/23 04:20:00| Finished.

No. What happened was you local client created an HTTP request to the public IP which the hostname in the URL resolved to. Your NAT box saw that this public IP was in fact being NAT'ed to a local host, and issued an ICMP redirect telling the client about the shorter route. If this didn't work right, your apache config probably doesn't mention the local IP in the virtualhost section or some such, but the HTTP result and/or the apache logs will give more info to track down any such details. You can also set up "split-horizon DNS" or perform similar tricks in /etc/hosts to convince machines on your LAN to lookup the www hostname as local IP rather than as public IP, which would remove the ICMP redirect from the situation entirely. -- -Chuck ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

An extra-long 80-wire cable is in use (to ad4). acd0: DVDR at ata-1-master UDMA33 ad4: 78167MB at ata-2-master UDMA100 dd if=/dev/urandom of=/home/test Wrote at 4485315 bytes/second: faster than I was expecting (based on linux's slow urandom function), but still slow enough to cause buffer under-runs. So the second question is: do I have to do anything special to enable buffer underrun protection? (with DVD+R's lossless linking feature, no data should be lost.) How important is running ATAPI/CAM? Obviously DVD burning was happening before the release of version 8, as far as I know. If running out of data is supposed to be abstracted away, did I find a bug that only shows up on old hardware or heavy load? (Or possibly drive firmware bug?)

TV test image generator using mencoder
For an amateur TV (ham) project, I'm searching for a convenient way to create a test image DVD or CD using FreeBSD's port mencoder. But I can't get this working. Maybe somebody on list has an idea of how to accomplish this. Input: a still image (jpg, gif, png) of a test picture, as shown on TV, already available Output: a VCD-compatible MPEG video file which shows the picture (which does not change) and plays a 1 kHz testing sound (sine wave); the length of "video" should be given in minutes More: a DVD-compatible output could be provided for better quality if needed The idea is this: With a set of, let's say 5 of such MPEG files, each lasting 10 minutes, I want to burn a VCD because that's what the player in use can play best. If it plays the in "repeat mode", every 10 minutes the test image will change, the sound will stay the same. The VCD can be done with mkvcdfs, I've already done that for other purposes, works good. As this player is a stand-alone device, there's no trouble getting a TV (video or even antenna) signal out of a PC. :-) Background: The test VCD can be played in continuous loop while the transmitter is running. This way, receiving tests can be done, as there is a good testing signal for making statements about video and audio quality. The combination of both, also using something standar- dized (instead of a camera input, showing the town from above or a look out of the window across the street) is buch better for making QUALIFIED statements about signal quality. Adjustments to the equipment can be done more easily. I've tried to do this with mencoder, but can't get any usable results. How would you suggest to get this done? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

thanks for the fstat tip

fstat -p $$ | awk '{if($4=="1"||$4=="2"){F[$4]=$5+$6+$8}}

I suppose there might be a problem if F never gets created or one of 1/2

something to make it a bit more robust.

I think your best bet for comparisons like this is to use case. I started
doing that back in the days when '[' would start a separate program:
case "$UID" in

die() {
echo "$@" >& 2

make -jX build(world|kernel): test results
Howdy, Occasionally the question pops up on the questions@ list about what the fastest -jX number is for a single CPU system. I had some spare time so I tried out a small matrix of possibilities.

NOTES: * I used the simple shell "time" command * /usr/obj was cleaned out before each run and I waited at least 30 seconds afterwards for write caching to settle down * This is my regular build host for my network * I built 4 kernels: 3 customized and GENERIC (see above for why) * Celeron 900, 256Mb of RAM, /usr/src and /usr/obj are both on their own set of spindles * /usr/obj consumes part of a vinum mirror on dual 40Gb 7200RPM Maxtor 6L040J2's (the remaining vinum filesystems weren't active during this test) * /usr/src is on a 2,1Gb Compaq ST32550N SCSI-2 drive * The operating system is on separate spindles RESULTS: buildworld -j2 buildworld -j3 buildworld -j4 buildworld == == == == real 57m10.367s 54m10.992s 55m7.494s55m1.459s user 38m5.436s38m20.852s 38m22.453s 38m23.056s sys9m2.801s 10m12.876s 10m17.140s 10m14.792s buildkernel -j2 buildkernel -j3 buildkernel -j4 buildkernel === === === === real 36m59.994s 36m58.988s 37m42.956s 37m31.627s user 29m35.597s 29m43.405s 29m43.846s 29m48.652s sys4m50.478s5m26.372s5m26.883s5m22.763s Thought this might be of some interest, -T -- Re: alt.sysadmin.recovery A fitting punishment for kindly naivete, to end up belonging here. - A.S.R. quote (Chris Johnson) pgp0.pgp Description: PGP signature

"Top posting" is a term that some people use to describe part of what you did with your reply: put the reply out of sequence at the top of the message instead of where it fits in logically in the thread.

Leaving white space after the "> " and leave empty lines between your text and the original text both make the result more readable. 9. Put your response in the correct place (after the text to which it replies). It's very difficult to read a thread of responses where each reply comes before the text to which it replies.

Yes, it would probably be better in this case. This, in
combination with the suggestion of "test-t 0" to check
if the script has been interactively called or not, looks
like a better solution.
However, the intial question does not make fully sure (at
least to me as a non-native speaker) if the intention is
(a) to check _if_ the script has been run via cron, or
(b) to check if the script has been run via _cron_. :-)

Depends. Let's say the script is scheduled at 3:00 and will
finish in about half an hour. The "evidence file" will only
be visible from 3:00 to ca. 3:30, so removing the "evidence
file" after the script has finished could lead to a false-negative
result ("has not been run"). This is also true for the more
simple solution using the touch command (no rm call at the
end of the script).

An easy way to do this is check /var/log/cron There are many other ways. - aurf On Sep 16, 2013, at 4:26 AM, Paul Macdonald wrote: > > Hi, > > Is there a simple way of testing whether a given script was called via cron, > > I'd rather find a solution that would work from within the script rather than > setting an environment variable in the crontab. > > thanks > Paul. > > (anyone here going to EuroBSD con?) > > -- > - > Paul Macdonald > IFDNRG Ltd > Web and video hosting > - > t: 0131 5548070 > m: 07970339546 > e: p...@ifdnrg.com > w: http://www.ifdnrg.com > - > IFDNRG > 40 Maritime Street > Edinburgh > EH6 6SA > > High Specification Dedicated Servers from £100.00pm > > > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Perl 5.8 - make test problem (shmget. msgget)
I am trying to upgrade Perl from version 5.005_03 to 5.8 on a 4.8-RELEASE FreeBSD VPS (virtual private server). I did a 'pkg_add perl-5.8.0_7.tgz' but I then removed it because I was getting this error: /usr/libexec/ld-elf.so.1: /usr/local/bin/perl: Undefined symbol "nl_langinfo" I then decided to dowload the source and compile it myself, but some of the tests fail: == Failed Test Stat Wstat Total Fail Failed List of Failed --- /ext/IPC/SysV/ipcsysv.t 78 1996816 16 100.00% 1-16 /ext/IPC/SysV/t/msg.t 78 19968 99 100.00% 1-9 /ext/IPC/SysV/t/sem.t 78 1996810 10 100.00% 1-10 /lib/IPC/SysV.t 78 1996816 16 100.00% 1-16 /lib/Net/Ping/t/110_icmp_inst.t 255 65280 21 50.00% 2 45 tests and 414 subtests skipped.

Test: Toshiba Satellite 2400, 4.7 and X
Hello, I've successfully installed FreeBSD 4.7-stable (now customized to run the sound card) on my Toshiba Satellite notebook; the video (1024x768, 16bit) is running ok, there was a problem with the keyboard (ssomme keyys wass haavving this behhavioor), and solved. I'm listing the X86Config lines that worked for me and the workaround for the keyboard. As I use a USB mouse, I've not paid attention to touchpad pointing device. I'd like to share some info with other users that are using this notebook and FreeBSD. There's one thing that I'm not getting solution: on text mode, my screen is reduced to a small 640x480 square. This LCD doesn't scale, I loss about 1,5 inch of screen on each side. Is there a hack to get text mode running @ 1024x768 ?? Regards, Fernando Monteiro = SOUND DEVICE DRIVER === The Yamaha AC-XG is supported by pcm. Look on the Handbook, there's install intructions. Kernel recompilation is required.

Re: TV test image generator using mencoder
On 01/24/11 17:45, Polytropon wrote: For an amateur TV (ham) project, I'm searching for a convenient way to create a test image DVD or CD using FreeBSD's port mencoder. But I can't get this working. Maybe somebody on list has an idea of how to accomplish this. Input: a still image (jpg, gif, png) of a test picture, as shown on TV, already available Output: a VCD-compatible MPEG video file which shows the picture (which does not change) and plays a 1 kHz testing sound (sine wave); the length of "video" should be given in minutes More: a DVD-compatible output could be provided for better quality if needed The idea is this: With a set of, let's say 5 of such MPEG files, each lasting 10 minutes, I want to burn a VCD because that's what the player in use can play best. If it plays the in "repeat mode", every 10 minutes the test image will change, the sound will stay the same. The VCD can be done with mkvcdfs, I've already done that for other purposes, works good. As this player is a stand-alone device, there's no trouble getting a TV (video or even antenna) signal out of a PC. :-) Background: The test VCD can be played in continuous loop while the transmitter is running. This way, receiving tests can be done, as there is a good testing signal for making statements about video and audio quality. The combination of both, also using something standar- dized (instead of a camera input, showing the town from above or a look out of the window across the street) is buch better for making QUALIFIED statements about signal quality. Adjustments to the equipment can be done more easily. I've tried to do this with mencoder, but can't get any usable results. How would you suggest to get this done? http://mplayerhq.hu The docs cover all that, and mencoder can output in vcd or dvd format. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
Emulators to test non-x86 FreeBSD ports?
Hello list, are there any emulators out there that can run the non-x86 versions of FreeBSD on a FreeBSD/i386 or FreeBSD/amd64 host? I'm especially interested in trying FreeBSD/sparc64 port, but I'd also like to test the FreeBSD/powerpc and the FreeBSD/arm ports on an emulator, before seeking real hardware. Oh, and btw, what kind of affordable SPARC-based desktops with newish SPARC processors (i.e. above UltraSparc IIIi) would you recommend for testing? I've read this page: http://www.freebsd.org/platforms/sparc.html but I'm at a loss as to what vendor, model etc. to get.

dump/restore (to DVD+R) test failure
Hello, It took reading the source code of a backup front-end to figure out that "incremental backups" are not the same thing as "multiple incremental backups on the same medium; spilling over to the next disk if necessary." As the handbook (section 18.12.1) says, dump has quirks due to its design dating back to 1975. Optical write-once media was punch tape or cards. Seeking to the middle of the media was time consuming, so daily tapes were simply written from the beginning, then rewound. So, knowing this, I decided to test a full dump and restore to DVD+R media, following the example in the dump(8) man page. I suspect that the example was written with DVD-R in mind, but according to wikipedia, http://en.wikipedia.org/wiki/DVD-R#Recordable_DVD_capacity_comparison the smaller DVD+R media can handle the example in dump(8) with 184 2048 byte blocks to spare (implying the example intended 3576 spare sectors). The package for the DVD media just says "4.7 GB" with only 2 significant digits. I used the following command for the dump: $/sbin/dump -0u -L -C16 -B4589840 -P 'growisofs -Z -dvd-compat /dev/cd0=/dev/fd/0' /home Growisofs said 4700372992 bytes were written on the first disk (my notes don't record exactly which disk that was). That works out to 4590208kiB or 2295104 sectors. Edit: This matches the Wikipedia number; I assumed it to included zero padding I tried the restore on a fresh freeBSD 8.0 install with no user accounts created (and atapicam not yet enabled): dusty# cd /home #restore -r -P 'dd if=/dev/acd0 of=/dev/fd/1 bs=2048 count=2294920' warning: ./.snap: File exists expected next file 706561, got 4 unknown tape header type -365754194 abort?

I suspect those may be corruption caused by a buffer underrun or local vibration. Questions: 1. How do I determine which files (if any) are affected? is verbose mode required for that? 2. It appears the first disk lost 712 sectors of data (and a total of 896 sectors of capacity) with that read error. Should I just burn the disks 1024-4096 sectors short? 3. What is the best way to verify dumps at dump time? I still have the data on another disk. I can restore it with dd if need be. I verified the newfs command appears to create a ".snap" directory by default now.

Are kernel stress test results displayed online?
Before one of the releases, I remember, kernel stress tests results were online. Now I can't find them. Are they run? (I guess they must be.) Particularly would be interesting to see tests for FreeBSD 8.1-RC2, FreeBSD 8.0-STABLE and FreeBSD-9.0. Also does stress test only cover kernel or device drivers as well?
