It's an Alphaserver 4100, dual 5/300 with 512 MB RAM and one power supply,
running 5.0-RC3 (kernel is GENERIC plus the line from ccd(4)).  I had been
trying to compile a few large things from the ports collection, Beonex for
example, and all the compilations had finished so the main task was dd
if=zero of=da2 which had been running from /dev since a few minutes after
boot (only a 4 GB disk--I wonder why it's so slow).

$ strings /tmp/4100-20030113-cu4.log | grep degrees
System temperature is 23 degrees C
System temperature is 23 degrees C
System temperature is 23 degrees C
System temperature is 23 degrees C
System temperature is 24 degrees C

I was sitting next to it when it crashed, and I would have noticed if the
fans had stopped.  From earlier logs, I see that the temperature has
varied between 21 and 27 Celsius.  I don't know what it is now, but it
feels warmish when I'm wearing just a tee shirt.  There's a fan that
constantly blows air into the room, which points toward the back of the
computer.  Should I run the air conditioner more often?

I forgot to mention that after the crash, the LED on disk da2 remains lit,
as is the one on da0 (which contains /, /tmp, /usr, and /var but not
/home).  When I had the same disk drives attached to a PC, I could write
to them at about 45 kilobytes per second.  Multiplying that by 19 hours
gives about 3 gigabytes, and it was a 4 gigabyte disk.

Re: WARNING! New GNU Tar in 5-CURRENT could erroneously create worldwriteable dirs

2002-06-06 Thread Trevor Johnson

 I've just noticed that something wrong with the new tar in the base
 system (1.13.25) - when extracting some archives it creates 777 dirs,
 while permissions in the archive itself are OK (for example GNU make
 make-3.79.1.tar.gz - top level dir gets 777 as well as several
 other lowel level dirs). The issue is under investigation.

The latest version on ftp://ftp.gnu.org/gnu/tar/ is 1.13.  The ones on
ftp://alpha.gnu.org/gnu/tar/ (and everything else on that site) are
considered unstable.  I suppose it's too late to suggest tar 1.13 as a
starting point, but maybe this could be kept in mind when importing other
GNU products.

The point I was trying to make is perhaps better conveyed by
ftp://alpha.gnu.org/README .

 Tar 1.13 is 3 years old, and has many bugs (incremental backups are
 unusable, for example).

I don't know why the GNU tar programmers decide that certain versions are
stable and others are unstable.  I do know that the former are found on
ftp.gnu.org, and the latter on alpha.gnu.org.  Now you know too, in case
you didn't already. :-)

I just discovered Jorg Schilling's star
(http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/star.html)
.  He says that it supports POSIX.1-2001, which I assume dates from last
year.  It's available in the ports collection and it's under the GNU GPL.

The documentation for GNU tar 1.13.25 says that it complies with POSIX
1003.1b, which was drafted in 1987 and completed in 1990.  The GNU tar in
FreeBSD-STABLE is from 1993 and it still works most of the time!

According to Mr. Schilling's testing, GNU tar 1.13.25 has a bug:
ftp://ftp.fokus.gmd.de/pub/unix/star/testscripts/README.gtarfail . I guess
it qualifies as a non-trivial program. :-)

On my friend's BSD/OS system, there is no tar--or rather, it's just a hard
link to pax:

% ls -li `which tar` `which pax`
1819 -r-xr-xr-x  2 bin  bin  58288 Jun 12  1998 /bin/pax
1819 -r-xr-xr-x  2 bin  bin  58288 Jun 12  1998 /bin/tar

Their tar/pax hybrid must check its argv[0].  Isn't that evil?

od driver for -CURRENT

2001-02-05 Thread Trevor Johnson

I've made an attempt at an update for -CURRENT of Shunsuke Akiyama's od
driver for magneto-optical disks, which I got from his archives at
ftp://daemon.jp.freebsd.org/pub/FreeBSD-jp/OD/ .  I have only tested it a
little, but I'm able to do "tar cf /dev/od0 ..." under 4-STABLE and untar
under Linux 2.2.16 or FreeBSD 5-CURRENT.  If under -CURRENT I boot up
while the MO disk (a 640 MB one) is in the drive (Olympus MOS364), the
data read from it gets corrupted.  That happens with the da driver as
well.  I merged the changes from the da driver into the od driver, so I
probably brought the bug in too.

Anyway,
it's at http://people.freebsd.org/~trevor/src/od-20010203-current.diff.gz

 People who run -CURRENT should be able to read and write English to
 understand the code comments, report bugs, and post to the lists in English.

 "If you don't know what to do with -CURRENT, don't install it."

You seem to be working from the assumption that people who understand

Re: Other Linux stuff...

2000-12-06 Thread Trevor Johnson

 For trivial cases, the simplest solution would be to just remove
 /compat/linux/usr/bin/ldd and have our native ldd do the work. If
 something depends on the switches, this won't work.

At http://huizen.dds.nl/~frodol/glibc/problems.html it says:

 * ldd gives real strange output, sometimes...
   The ldd script that comes with glibc-2.0.6 handles libc5
   executables incorrectly, resulting in strange output. You are
   probably better off if you always use the ldd that comes with
   ld.so-1.9.9. Implement this by deleting or renaming
   /usr/i486-linux-libc6/bin/ldd

I've done this under Linux itself, and it worked well.

Re: randomdev entropy gathering is really weak

2000-07-16 Thread Trevor Johnson

 I found that I always got the same fortune quote after reboot, over and over 
 again. It means that /dev/random produce exact the same values after reboot.

There were some special instructions for the new random device:

2) If you do not have the randomdev module loaded, ssh will
   fail in strange and creative ways (like RSA or DH not working
   for strange reasons).

3) It is not built by default (except as a kernel module), so you
   either need to add the "options RANDOMDEV" like to your kernel
   config, or load it at boot time in /dev/loader.conf

4) Make sure that you update your /etc area (mergemaster is your
   friend). The rndcontrol(8) utility is now OBE, and no longer of
   relevance.

 Now, I must say, that there is no way we are going to add that hack back
 in ... it was a real mess and is simply not worth it, and when we 
 move to the interrupt threading model we can truely make the serial 
 interrupt SMP-safe and do away with the issue once and for all.

Looking at the old driver (src/sys/i386/isa/Attic/psm.c,v) I see a note
that the hardware offers a polling mode (not implemented in that driver),
where the mouse only sends packets after getting requests for them.  If
there are intractable problems with handling interrupts, perhaps that mode
could be used instead (maybe if no one had used the mouse recently,
polling could be done less often, to conserve CPU time).

 I don't know if the mouse problems are related or not, did anyone have
 jumpy-mouse problems before the SMP cleanup was committed? (i.e. in
 kernels then two weeks old for 4.0, and four weeks old for 5.0).

I'm running 4.0-STABLE from May 5 23:39 PDT and I found one of those
messages (just like Jordan's except for the hostname and time). I think I
was at the computer when it happened, but I don't remember any erratic
movement of the mouse pointer, nor have I ever noticed any under FreeBSD.  
I have XFree86 3.3.6 running from xdm, using /dev/sysmouse as the mouse
device.  I have moused running too, and was probably in text mode when the
tragedy^H^H^H^H^H^H^H error message happened. My computer has a Digital
Equipment Corp. PC7XS-CA three-button mouse, a Winbond W83977TF-AW I/O
chip, and Intel 440 BX chip set.

I saw this problem a long time ago, most memorably on an IBM PS/2 55SX
with an IBM mouse, under Windows 3.0.  Sometimes the mouse pointer would
move suddenly all around the screen, and programs would behave as though
someone were pressing the mouse buttons. Searching the Web, I see that the

Re: Quickie question on UDMA/33

 Western Digital Caviar hard drives that should support UDMA/33, as should
 the Chipset.
 
 Both boot up, trying UDMA mode, throwing ICRC READ ERROR's then kick back
 down to PIO mode 4.

 Bios's are set to do auto-chose pio/dma modes.

There may be a BIOS option that will disable DMA entirely.

 I've resolved to simply adding in the rc to reset them to pio mode, to get
 it over with (but I still get the errors at boot-up prior to the rc doing
 them).
 
 I simply use 'device ata' etc. forms in the knerel config.

You might try commenting out this option (if you're using it):

options ATA_ENABLE_ATAPI_DMA#Enable DMA on ATAPI devices

Re: Overwhelming messages from /sys/netinet/if_ether.c

2000-04-08 Thread Trevor Johnson

 I say with 99% certainty that assigning 0.0.0.0 to
 the interface is a requirement of dhcp.
 
 You can't stop using it and expect dhcp to work.

The Linux folks stopped doing it:

   2.0 supported the net interface 0.0.0.0 IP address convention (meaning
   the kernel should accept all IP packets). 2.[12] don't, hence things
   like many bootp/dhcp configurations which used this feature break.

   The proper fix is to modify bootp/dhcp clients to accomplish the same
   thing using raw sockets instead. I think dhcpcd
   (URL:http://www.phystech.com/download/dhcpcd.html) already works
   this way, but bootpc hasn't been updated yet.

Re: ata delay

1999-07-18 Thread Trevor Johnson

 Hi!

Hi, Thomas.

 I switched to the ata IDE driver some time ago. Since then, booting
 stops for about 30 seconds when the driver is installed. It didn't
 happen when using the old wd driver.

In /usr/src/sys/i386/conf/LINT it says:

# This option allow you to override the default probe time for IDE
# devices, to get a faster probe.  Setting this below 1 violate
# the IDE specs, but may still work for you (it will work for most
# people).
#
options   IDE_DELAY=8000  # Be optimistic about Joe IDE device
