Oh, doom does not require fp, its integer only and on 100MHz Pentium it

our pops some time around 1996 :)



I was referring to the 100MHz 486 you looked at.

I'd still get an fpu so you can install a largely unpatched OS of your
choice even if the fpu is redundant beyond installing the OS.

I guess you looked at the Soekris stuff and discounted it. Shame,
because a lot of folks find them useful with *BSD.


The last I checked Soekris boards were using more power.  We use similar 
boards from pcengines.ch for wireless routers.  This application I am 
working on needs a computer with VGA and sound interfaces.

I had the same problem installing 6.2 release.
This is mentioned only once in the section 2.13.1 of the handbook. I think
that many beginers tend to go step-by-step on the installation and when
learning something new and this notion should be pointed out somewhat
earlier in chapter 2.

saslauthd exited on signal 11

[D Hill]

I have two server installs of FreeBSD 7.0-RELEASE. One is running AMD64 
and the other is running i386.


The one running AMD64 is getting an error at SMTP time of:

  535 5.7.8 Error: authentication failed: generic failure

Once this happens, the saslauthd thread that took the connection causes 
this line to be written in ../messages:


  Jun 12 05:51:01 smtpgate kernel: pid 37374 (saslauthd), uid 0: exited on 
signal 11 (core dumped)


I've looked for the core dump but can't find it anywhere.

Both servers are running identical versions of:

  smtpgate# pkg_info |grep cyrus
  cyrus-sasl-2.1.22_1 RFC  SASL (Simple Authentication and Security Layer)
  cyrus-sasl-saslauthd-2.1.22 SASL authentication server for cyrus-sasl2

Does anyone know if there is an issue with cyrus sasl and/or cyrus 
saslauthd on AMD64? Or is there anything special needed to be done?

Well, gentlemen, I may finally have a clue!  The guy who set up
my networking stuff and whatever database ports there are
did not install mysql50-server. Just the -client side.  This
fellow is the salt-of-the-earth type, ETC, but evidently didn't
get into phpbb or whatever I've been trying to do.

The -server side is building on my serious antique Kayak now.
My thanks to both you guys; the dev.mysql.com site is chock full

FWIW I had major issues with 173.14.05 (X.org crash to syscons at random
and usually immediately when using GLX stuff) and reverted to 169.12 which
is running once again without issue.

Anyhow, I remember experiencing issues like what you're mentioning though
it's a while ago so my memory is hazy.  IIRC, it comes from conflicts
between the Mesa and Nvidia libraries, and there was some voodoo that
seemed to help (though I'm not sure if it's still used), which was to
set `USE_NVIDIA_GL=yes' in /etc/make.conf.

There may also be some library rebuilding needed once that make variable
has been set (libGL and friends).

Disclaimer: the above advice is based on a hazy memory of dealing with
similar issues and may be totally inaccurate and/or snake oil.

Re: Poor read() performance, and I can't profile it

[Chuck Swiger]

On Jun 11, 2008, at 12:42 PM, Kirk Strauser wrote:
I'm almost ready to give up on this.  I've gone as far as completely  
rewriting the
original C++ program into straightforward C, and still the  
performance is terrible on

FreeBSD versus Linux.


On Linux, GNU libc buffers file data much more extensively than  
FreeBSD's libc does.  It means that doing things like reading a dozen  
bytes or so at a time is not intolerably slow on the former system,  
but that doesn't mean that it's a great idea either.


If your data files are small enough to fit into 2GB of address space,  
try using mmap() and then treat the file(s) as an array of records or  
memoblocks or whatever, and let the VM system deal with paging in the  
parts of the file you need.  Otherwise, don't fread() 1 record at a  
time, read in at least a (VM page / sizeof(record)) number of records  
at a time into a bigger buffer, and then process that in RAM rather  
than trying to fseek in little increments.


(This is the opposite of calling setvbuf() to set the I/O buffer to,  
say, 13 bytes...)


Also, if you're malloc'ing and freeing buf & memohead with every  
iteration of the loop, you're just thrashing the malloc system;  
instead, allocate your buffers once before the loop, and reuse them  
(zeroize or copy new data over the previous results) instead.


Regards,
--
-Chuck

Also note that on the FreeBSD machine, I have enough RAM that to  
buffer the entire
file, and in practice gstat shows that the drives are idle for  
subsequent runs after

the first one.

Right now my code looks a lot like:

  for(recordnum = 0; recordnum < recordcount; recordnum++) {
buf = malloc(recordlength);
fread(buf, recordlength, 1, dbffile);

   /* Do stuff with buf */

   memoblock = getmemoblock(buf);
   /* Skip to the requested block if we're not already there */
if(memoblock != currentmemofileblock) {
currentmemofileblock = memoblock;
fseek(memofile, currentmemofileblock * memoblocksize, SEEK_SET);
}
memohead = malloc(memoblocksize);
fread(memohead, memoblocksize, 1, memofile);
currentmemofileblock++;

   /* Do stuff with memohead */

   free(memohead);
free(buf);
   }

...where recordlength == 13 in this one case.  Given that the whole  
file is buffered in
RAM, the small reads shouldn't make a difference, should they?  I've  
played with
setvbuf() and it shaves off a few percent of runtime, but nothing to  
write home about.


Now, memofile gets quite a lot of seeks.  Again, that shouldn't make  
too much of a
difference if it's already buffered in RAM, should it?  setvbuf() on  
that file that

gets lots of random access actually made performance worse.

What else can I do to make my code run as well on FreeBSD as it does  
on a much wimpier
Linux machine?  I'm almost to the point of throwing in the towel and  
making a Linux
server to do nothing more than run this one program if I can't  
FreeBSD's performance

more on parity, and I honestly never thought I'd be considering that.

I'll gladly give shell access with my code and sample data files if  
anyone is

interested in testing it.

Re: Java Dilemma

$ firefox
INTERNAL ERROR on Browser End: SendRequest: Read of ack failed: 0

It's interesting to note that you don't have to download the tzupdater
tool from Java (which requires you to create an account with their site).
In order to avoid getting that file just edit the Makefile prior to
running make. This may be necesarry for java to work, but it gave me the
same error with and without that TZ package. Anyway, which firefox
version are your running? I'm using firefox 2.0.0.12.

This issue is very easily solved with open source code, as you
can simply read the code before running it.  That is one of the
reasons that most crypto implementations that people trust
to actually keep things private are open source.

Such as people who don't read the source for any password generator

It would be nice if it could be patched and a portaudit warning issued
for it so users could update.

The patching would be beyond me unfortunately...or fortunately, as I
would likely make it *really* insecure ;)

two monitors, two displays, one PC

[John Wynstra]

In the last 4 months I bought a new monitor to replace the one that 
clunked out in me.  I am currently using it with an old PS2 type 
keyboard and mouse attached to a creaky old desktop that will eventually 
be replaced.  Likely I will want to replace it with a laptop with wifi 
and a lot more memory and hard drive so that I can take it with me.  Can 
I still use the old monitor as a second display?


Can this be done?  Is it done?  What are the issues?

I like sysutils/pwgen too.

In it's default state it will give a screenful of semi-pronounceable
passwords from which you pick one. 

It can also be used in a shell script to generate single passwords.

Having the password semi-pronounceable avoids the sticky-note problem
to a large extent as they're easy to learn.

Can also generate gibberish, if that's your choice. Widely tunable.

For password containment i.e all my online passwords, I use a shell
script with gpg and a strong password.

So in theory, I only have to remember my user login and the password
for gpg. In practice, I remember a few more that I use regularly.

Yes it is worrying.  The next time I reboot the one server I've got

then on reboot I will disable SVM in the BIOS.

Your mysql server already has a password for user root.

2 options

1 - mysqladmin -u root -p password

Of course I think you dont know current password or you wouldnt be
askingso second option

Read
http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html#resetting-permissions-unix

with that steps you will reset root password

There are actually two versions of this in ports: sysutils/pwgen and
sysutils/pwgen2. The latter is an independent rewrite rather than a
version 2, and seems to be much more secure. 

The problem with pwgen is that its PRNG is very weakly seeded, making
it vulnerable to simple brute-force attacks. As most of the entropy
comes from the time (in *integer* seconds), it's particularly weak if an
attacker knows roughly when the password was generated. An attacker with
local access may even be able to compute the passwords directly. 

pwgen2 gets random numbers directly from /dev/random, which is how
it should be. 

IMO pwgen should be removed from the ports tree, or failing that should
be patched to use arc4random(), which is self-seeding. I don't really
see the point in keeping it though.

Re: mfi freebsd7

[Patrick C]

Great info, Kalin.

I have several boxes with LSI controllers, the PERC 5i works
wonderfully with FreeBSD (though the Dell 6850 sucks), and I have a
couple boxes with Supermicro boards with built-in LSI MegaRaid,
however it's done in software. This means that the mfi controller
works fine as individual disks, but will not support any RAID levels
in FreeBSD. You're probably almost as well off using gmirror anyway.

I've started using 3ware cards again after a bit of a hiatus and they
work great, and the FreeBSD support is good.

My next experiment is going to be some HighPoint cards. I'm not sure
at this point I wold trust them with my important data, but what's
cool is they are very inexpensive cards, show up in computer stores
like Fry's, and seem to have pretty decent FreeBSD support for their
size. I'm going to try an 8-port in my desktop (I use it for some
pretty serious MySQL work at times) soon... IMHO if the cards are
decent it'd be nice to reward them for their efforts by putting some
money their way.

It is my understanding that since 1995 all computers must have a
hardware back door that permits undetectable access by the government to
the computer. This capability can be implemented using System
Monitor(Maintenance) Mode which is built into all x86 computers now. It
would appear that, if you are connected to the internet, the government

Perl 5.10.0

Just before FBSD-7 was released, I asked if Perl 5.10.0 would be
included in the new version. I was informed that it would not be;
however, it would be released shortly after FBSD-7 was released.

Well, FBSD-7 has been out for a while now; however, I still do not see
the updated version of Perl. Is there any specific reason that it has

You might also consider mldonkey, which does the the file sharing via
a daemon (mlnet) which you can connect to via various methods,
including telnet, a web interface, and several GUI applications. It's
primarily an ed2k client and its BT support isn't very sophisticated,
but it does have the advantage that the daemon will start from rc.d and
run in the background without any manual intervention.

That is a very broad question without a simple answer. It depends among
other things on the purpose of the machine and the knowledge of the
administrator. 

E.g, if you are creating a workstation that doesn't run externally
accessible servers you could configure the firewall to block all
incoming new connection requests. That will go a long way toward
safeguarding the machine against network attacks.

There is no way to safeguard a machine that an attacker has physical
access to; he could e.g. steal the harddisk and read your data at his
leisure (unless it is encrypted on-disk, e.g. with geli(8)). Also, no OS
can defend against social engineering attacks. 

I would not worry overly much about spyware.  Most if not all of those
are windows binaries. Also, unix mail clients as a rule do not execute
scripts embedded in mail messages.

You could mount /home and other partitions where users have write access
like /tmp with the noexec option. Note that that wouldn't block the execution
of scripts, just binaries.

Re: Question about torrents via console

[Luke Dean]

   Hi all.  Ok, I'm curious of something.  I've done torrents before via 
the graphical interface before, but I want to setup a way to download isos 
and various FOSS apps via bittorrent, but I want to do it via the console so 
I can start a torrent in screen and then walk away, allowing my server to 
finish the work without having to leave my main workstation running to do the 
work like I normally do.  I'm using bittornado right now, and if there's a 
way to do this, I'd love to know how.


I run bittornado's btlaunchmany.py script through screen (sysutils/screen) 
for the very reason you describe.  It's been working great for years.

It should run FreeBSD just fine.   Check the hardware compatibility

The Linux compatibility layer worked well.  Should be no problem.

FreeBSD and User Security

[David Naylor]

Hi All,

Today I read an article describing how my government had lost ZAR200 000 000 
from fraud.  This is just under $25 000 000.  The article credited this loss 
largely due to the use of spyware.  

My question is how secure is FreeBSD (including KDE, GNOME and XFCE) to 
attacks, including cracking and spyware.  In addition, is there anyway to 
prevent a user from executing a program that is not owned by root (i.e. any 
program installed by the user), this would prevent spyware being installed 
(assuming root has been properly locked down) and subsequently run.  

If anyone, in addition, has answers for Linux and *BSD it would be great to 
know as well.  

Best Regards

David

Heikki,

Gentoo (http://www.gentoo.org) is a pretty easy install and is the most
closely aligned Linux distribution I've seen to the "build it from source"
mentality.  It's gotten fancier over the years but still has at its core
the notion of building blocks and doesn't push binary package distribution
the way most seem to these days.  Whether it'll install on an FPU-less
system I don't know.  Might be worth a look.

Please do report back with what you ultimately find works; this is a
source of interest for me and I'm sure others.

I used to do a lot of CAD and buying a machine without a co-processor

 kqemu, if there isn't too much overhead, on my amd64 laptop until

The "Flashplugin"s in the ports collection are the Linux
versions, which require both a) an interface between the plugin and
the browser and b) the Linux emulation layer.
My last information about Flash9, gleaned from various FreeBSD
mailing lists: the problem is thought to be _somewhere_ between the
plugin and the emulation layer.  This is roughly equivalent to
saying there is a mouse somewhere in .
The current set of permanent pest control experts (the Linux
emulation crew) has considered the matter and decided this is not
worth the time.  As of the time I heard about it, this was in part
because a) Flash9 had tangible problems under Linux and b) even if
they knew what was broken in the plugin the track record of Adobe
being willing to fix it was poor.  (Volunteers for a special mission
should apply on the emulation@ list.)
Don't get me wrong - I'd love to have a working Flash
even under emulation.  But after _years_ of having hopes raised and

an open spec API (ABI??).


Great information, Robert.  Thanks.

I'm going to take this opportunity to preach. Everyone should be using  
a good password management system.  Otherwise people will use either  
weak passwords or will use passwords which are predictable from other  
passwords.  (That is using the same password or variants of the same  
password for many separate realms.)


I don't run FreeBSD on desktops so I haven't looked at the various  
tools available.  On OS X, I use 1password which makes excellent use  
of the OS X Keychain system, and has terrific webbrowser integration.   
I'm fairly sure that the Apple Keychain libraries have been or can be  
ported to FreeBSD, but it might require GnuStep.


On Window's I recommend Password Safe.  In ports, sysutils/pwsafe  
provides a CLI utility that can manage Password Safe data.  And  
security/gorilla provides a tcl/tk GUI for pwsafe.  I've used both on  
OS X, and the work fine, but I much prefer 1password in that  
environment.


I've never looked at things like kwallet or other Unixish password  
management systems.  But once again, I recommend that everyone use a

I'm almost ready to give up on this.  I've gone as far as completely rewriting 
the

terrible on 
FreeBSD versus Linux.  

On Linux:

On FreeBSD:



Also note that on the FreeBSD machine, I have enough RAM that to buffer the 
entire 
file, and in practice gstat shows that the drives are idle for subsequent runs 
after 
the first one.

Right now my code looks a lot like:

   for(recordnum = 0; recordnum < recordcount; recordnum++) {
buf = malloc(recordlength);
fread(buf, recordlength, 1, dbffile);

/* Do stuff with buf */

memoblock = getmemoblock(buf);
/* Skip to the requested block if we're not already there */
if(memoblock != currentmemofileblock) {
currentmemofileblock = memoblock;
fseek(memofile, currentmemofileblock * memoblocksize, SEEK_SET);
}
memohead = malloc(memoblocksize);
fread(memohead, memoblocksize, 1, memofile);
currentmemofileblock++;

/* Do stuff with memohead */

free(memohead);

...where recordlength == 13 in this one case.  Given that the whole file is 
buffered in 
RAM, the small reads shouldn't make a difference, should they?  I've played 
with 
setvbuf() and it shaves off a few percent of runtime, but nothing to write home 
about.

Now, memofile gets quite a lot of seeks.  Again, that shouldn't make too much 
of a 
difference if it's already buffered in RAM, should it?  setvbuf() on that file 
that 
gets lots of random access actually made performance worse.

What else can I do to make my code run as well on FreeBSD as it does on a much 
wimpier 
Linux machine?  I'm almost to the point of throwing in the towel and making a 
Linux 
server to do nothing more than run this one program if I can't FreeBSD's 
performance 
more on parity, and I honestly never thought I'd be considering that.

I'll gladly give shell access with my code and sample data files if anyone is 
interested in testing it.

silent data corruption is common, while crashes can be under specific

What do you mean, wrong data generated by programs?  If


wrong data generated by program because of hardware problem.


You usually notice it when it's too late and the last
good backup media was already recycled.


not that bad, but of course - i make backups.

> i think all your cases wasn't disk, but general hardware problems.

In my case it was a disk with media surface errors, and
the disk failed to report the error properly to the OS.
Instead it just returned bad data.


so i am just happy to never having it, while normal disk failures are 
quite common..




> ZFS may help detect it, or it may not. if it helped for you.

Please stop spreading FUD.  There is no "may or may not".
If a disk returns bad data, ZFS _will_ detect it.

please read more carefully. i didn't say it.

i just say that "disk returning bad data" is very rare case, lots of 
other - more frequent - hardware problems will not be detected.


if you like to give lots of CPU power and disk bandwidth for calculation 
of checksums on each read/write - then OK.

if you think you are secured this way - then OK.

i just say it doesn't make lot of protection against bad hardware, not 
worth the expense.


i probably shouldn't type that point as it can be turned off in ZFS.

Note that using TCP on top of TCP can cause certain
problems, especially when packets are lost.  There's
a good explanation on this page:

http://sites.inka.de/sites/bigred/devel/tcp-tcp.html

The short story is:  If any packets are lost, the
resend-algorithms of the two TCP layers will start
to interfere with each other, because both have their
own timeouts and will start retransmitting packets
at their respective levels.  This is bad, because it
leads to a snowball effect.

If you can guarantee that there will be zero packet
loss, then TCP is fine.  Otherwise I recommend to
run the VPN on UDP.

Correct.  It does happen.

A broken processor usually results in random crashes, not
silent data corruption.  Broken memory will be noticed if
it supports ECC, otherwise it will also result in crashes,
most probably.

 > which will make ZFS calculate checksum wrong on write, 

Even if that happens (without crashes or other things that
you'll notice immediately), the error will be detected by
ZFS and fixed ("healed") if possible, i.e. when running
with redundancy and at least one copy has a good checksum.

(GELI can only detect, but not fix.  ZFS can fix it, too.
I assume in theory it would be possible to make geli co-
operate with gmirror so it could fix bad blocks, too, but
that's just theory.  ZFS is reality.)

 > or even calculate checksum right of wrong data generated by badly 
 > operating programs.

What do you mean, wrong data generated by programs?  If
a program generates wrong output, there's nothing any
file system could do about that.  That's not the file
system's job at all.  The file systems job is to ensure
the integrity of data written to the disk, and ZFS does
exactly that.

 > given the complexity of motherboard+CPU etc. to complexity of disk 
 > hardware, i don't think "silent disk failure" happens often.

Fortunately it doesn't happen often, but it does happen.
And when it happens, you are in really serious trouble.
You usually notice it when it's too late and the last
good backup media was already recycled.

In my case it was a disk with media surface errors, and

Please stop spreading FUD.  There is no "may or may not".
If a disk returns bad data, ZFS _will_ detect it.
Silent corruption _cannot_ happen with ZFS, except if
you disable the checksumming feature intentionally.

Please elaborate what the problem is, if you think there
is one.

As I said:  You were lucky.

Many people suffer without knowing.  :-)

I do suffer from UFS' shortcomings on many machines
on which I can't use ZFS (or other file systems) for
various reasons.

The "Flashplugin"s in the ports collection are the Linux
versions, which require both a) an interface between the plugin and
the browser and b) the Linux emulation layer.
My last information about Flash9, gleaned from various FreeBSD
mailing lists: the problem is thought to be _somewhere_ between the
plugin and the emulation layer.  This is roughly equivalent to
saying there is a mouse somewhere in .
The current set of permanent pest control experts (the Linux
emulation crew) has considered the matter and decided this is not
worth the time.  As of the time I heard about it, this was in part
because a) Flash9 had tangible problems under Linux and b) even if
they knew what was broken in the plugin the track record of Adobe
being willing to fix it was poor.  (Volunteers for a special mission
should apply on the emulation@ list.)
Don't get me wrong - I'd love to have a working Flash
even under emulation.  But after _years_ of having hopes raised and
dashed I'm pretty much waiting for Flash10 which is supposed to have
an open spec API (ABI??).

Good find - it looks like Mail is using application/pkcs7-signature, 
while Thunderbird is using , application/x-pkcs7-signature, which is 
allowed. According to http://en.wikipedia.org/wiki/S/MIME#Caveats, 
either is an acceptable mime type. So I guess I should email the list 
admins and ask them to allow that mime type, since they are allowing 
signatures anyways on the list.

At least on Debian, the bittornado port includes the curses interface. 
It was called 'btdownload.curses' I think. It's possible it is all ready

Another possibility is to run a GUI client in a VNC session. I do this 
with Azureus and am quite pleased with it.

I have used net-p2p/ctorrent and net-p2p/rtorrent in the past and they 
have worked well.  Both are console bittorrent clients.  I am sure there 
are many others.

Obviously you have been lucky to never be a victim of
silent disk corruption (or you just haven't noticed).


what you mean. that disk wrote the data wrong and doesn't detect it on 
read? i would mean broken disk processor, it's memory etc.


possible - as much as broken main processor, main memory, some of chips on 
motherboard etc. - which will make ZFS calculate checksum wrong on write, 
or even calculate checksum right of wrong data generated by badly 
operating programs.


given the complexity of motherboard+CPU etc. to complexity of disk 
hardware, i don't think "silent disk failure" happens often.


i think all your cases wasn't disk, but general hardware problems.
ZFS may help detect it, or it may not. if it helped for you.

even without ZFS it WOULD cause problems with programs like random 
crashes.



personally i often got disk failing the way that it was unable to read or 
write giving an error, but never things like that.



You're free to use UFS, of course, and keep suffering
from its shortcomings.

As far as I know (not 100% sure, though), the NFSv4 client
is under active development.  You might have better luck
getting a useful answer on the -fs and/or -hackers lists.

I'm setting CPUTYPE on all of my machines for many years,
without the slightest problems.  No pain at all.  They're
all kinds of different processors, c3-2 (VIA), athlon64,
and so on.  In some cases the difference is very noticable.

Oops, sorry, I was not specific enough:

FreeBSD 4 or older NetBSD are no go:

The computer I am doing this is not old, it is otherwise brand new, but 
it uses an embedded cpu, a 486 clone as SoC without math.  See 
www.compactpc.com.tw, eBOX 2300SX.  It is very low cost, runs on about 
3W of power with CF card as mass memory, 128M, 3 USB2, serials, sound, 
etc, it has VESA form factor so you can attach it behind many LCD 
displays, etc. They have beefier models, but this one is cheapest and 
uses least power, latter of which is the more critical requirement for us.


We would like to use it for certain control applications.  Linux works, 
has been tested, but requires patches (turn math emulation on, add 
support for built-in ethernet, bug workaround).


I don't know if this machine is going to be sited on an insecure
network or not. If it is, then you'll probably be using ssh. Without
a math co-proc to do the crypto, it will be horrendous. I don't even
know if ssh would work with an architecture without a maths unit.


You apparently do not use the source :), go and grep double and float 
from some of the most common programs you use (games, scientific stuff 
and crappy UI code excused).


> If it can't work with ssh, then you might be restricting your market.

ssh does not use any floating point for any crypto algorithm.  Oh, 
openssh does use doubles, it prints some ratios in some places, such as 
how many percent of something has been transferred.  It seems to be 
stirring random numbers as floating point non-exactness does is not a 
bother there, but that is not used past session init.  There is no 
human-noticeable effect on normal ssh use.


I was one of the first guinea pigs for original ssh.  We did have plenty 
of non-math cpus back then, and I did run ssh on non-fpu hardware until 
two years ago.  We did run backups and configuration tasks over ssh on 
number of non-fpu computers acting as routers and other servers those 
days.  Today's games might be different, but that is not what we do on 
these embedded computers...



I think you are punishing yourself unneccesarily by going with a
processor without maths. You restrict the software (both OS &
application) you can run.


Applications cannot tell the difference between math emulation and 
hardware from anything else than performance, so there is no code 
difference in application layer, and kernel does not do fp at all, other 
than trapping fpu instructions and emulating them on non-fpu hardware. 
Kernel itself does not do fp math.


I do not quite understand where this fear of non-fpu came from, as it 
made no practical difference just few years ago for anything but 
scientists in labs and intensive cad/graphics work.  In particular I do 
not understand why people have an idea that everything uses floating 
point.  Very few programs do heavy math processing, most common use is 
to double divide two longs to print out some statistics when program ends.


The problem with is that while FreeBSD 4 seemed to boot on it, it did 
not recognize any peripherals as they are new.  Old OS's are not really 
what we want, this is not one-off but volume product, it will be 
internet-connected so we need bugfixes and we need support for latest 
chipsets on 802.11 cards etc.


There is another similar CPU, even slower and less power consuming, I do 
not remember the part number, I think it was about 100 MHz 486 without 
math as well.  This was some manufacturer of microcontrollers.


Can't you find a manufacturer that makes something similar with a DX
instead? Or can you email this company and ask them how much it would
cost to run off X units with a 486DX rather than SX?


This is not 486, it is System-on-Chip thing.  There are couple of very 
cheap SoCs, which do not have math, but performance is otherwise 
adequate for most applications.  They are much faster than 486SX, by 
5-10 times factor, so they are becoming popular on embedded devices.

You need to take the "Message-ID" header of the message
that you're replying to, and put it into the "In-Reply-To"
header of your response.  That's what a standard mail
client does when you reply to a message.

The "In-Reply-To" header is used by clients and webmailers
to identify the thread and the order of messages within
that thread.

I've never used Gmail or Yahoo, so I don't know if they
provide a way to manually set the "In-Reply-To" header.
If they don't you're out of luck, I'm afraid.

By the way, I'm in a similar situation:  I'm not subscribed
to the lists, but I read them with a news client via an
NNTP gateway.  That gateway is one-way, i.e. I cannot post
follow-ups to the news groups.  Instead I use the reply-by-
mail function of the news client.  This works well, because
the NNTP gateway sets the "Reply-To" back to the list's
mail address (unless there already was a Reply-To header in
the original mail, which is kept), and I configured my news
client to copy the Message-ID into an In-Reply-To header,
so it works as expected.

Best regards

Two ... I like to be able to see the flash video but all it does is freeze

I can't seem to get linux-flashplugin7 anymore due to the restricted status.
Flashplugin9 locks up also, which we all know already. I have heard gnash

I've got a question.  A friend has been loaning me his old laptop at

Obviously you have been lucky to never be a victim of
silent disk corruption (or you just haven't noticed).
There are other people who didn't have that much luck,
including me.

ZFS' checksumming and self-healing is a blessing.  If
you don't know how it works and call it marketing blah,
then I suggest you read up on it a bit.

And by the way, it doesn't take any significant amount
of CPU power on hardware that is not ancient.  I agree
that ZFS is not suitable to run on ancient hardware.
It isn't designed for that.

You're free to use UFS, of course, and keep suffering

Yep.  Sorry.  Any of those would be a better candidate.
I'd simply forgotten about port management tools modifying

Here's what I found:

virtual IP for client1/192.168.0.1:53237: 10.8.0.6


This was interesting since that IP wasn't being set by the client. I'd 
been manually setting it to 10.8.0.2, which caused this:


Wed Jun 11 12:50:04 2008 client1/192.168.0.1:53237 MULTI: bad source

Changing it to 10.8.0.6 allowed the VPN to work over the tunnel. I could 
access the VPN server on .1.


Bridging still doesn't work - and I don't see any traffic over the 
interface either. Unfortunately, my laptop's network card just kicked 
the dust so it's going in for servicing. I might test it out using the 
Windows client on my desktop, but since it's inside the network all 
ready I imagine it would be much harder to test.

I'm setting CPUTYPE on all of my machines for many years,
without the slightest problems.  No pain at all.  They're
all kinds of different processors, c3-2 (VIA), athlon64,
and so on.  In some cases the difference is very noticable.

Having said that, it's certainly worth trying whether your
problems are gone when you compile without that setting.

Do you have any other unusual settings, such as non-standard
CFLAGS or anything?

BTW, I once was bitten by a similar problem, when building
software failed in strange ways, it turned out I had a bad
variable in my environment that was picked up by some build
scripts.  Maybe it's worth a try to run your ports builds
with a clean environment ("env -"), or try to install
binary packages instead of building ports yourself, in
order to narrow down where the problem is.

Re: Is FreeBSD suitable for my thinkpad T61 ?

[herbert langhans]

The linux progs run very well, what I can tell with my modest amount of
programs using this mode. BSD uses a seperate directory what contains all
linux-bins and it integrates well. Also the speed is like a normal Linux
distro. Maybe it is a good idea to get an old 20GB harddisk, change it
and give it a try while leaving your old HD with your current
installation intact?

This script might be useful for that purpose:

http://www.secnetix.de/olli/scripts/pidtrace

Given the process ID of the "find" process on the command
line, it will print its parent processes all the way up to
init(8).  That way you can easily find out if the "find"
was started by a cron job, by an rc.d script, or something
else.

FreeBSD uses all memory for caching, as far as possible.
Free memory is wasted memory.

 > a bugreport on it,

No.  It is clearly documented in the mdconfig(8) manpage:
"If the -o reserve option is not set, creating and filling
a large malloc-backed memory disk is a very easy way to
panic a system."

As I said above, you probably don't want a malloc-backed
memory disk (which means it consumes non-pagable kernel
memory), but a swap-backed disk (which is cached in regular
RAM and backed by swap).

If you're absolutely sure you want kernel-malloc for your
memory disk, you need to increase the kmem limit (see
"sysctl vm | grep kmem").

One of the biggest problems with random passwords is that they
