I didn't see if anyone came up with an answer for this one.

Top, with the "M" command, would be my first thought.

However, the problem may be associated with shared memory... try looking
at "ipcs"?

Re: [vox-tech] Questions about building my own box

2002-01-17 Thread Richard Crawford

I agreed, Star Office 5.2 sucked.  But 6.0b is a vast improvement over 
5.2; a number of the major issues have been fixed -- it no longer does 
the hostile takeover of your desktop that it once did, a feture that 
drove me away from it some time ago.

Personally, I'm partial to WordPerfect and have been since 5.1 for DOS. 
  I'm saddened that Corel no longer supports to Linux edition of 
WordPerfect.

Netscape 4.7 is okay for Linux; haven't tried 6.2  Mozilla 0.9.7 is 
pretty good; I'm looking forward to seeing Mozilla 1.0 in about 2057 or 
so.  Konquerer is more than adequate for almost all of my browsing needs.

I've finally reached the point where I'm only loading Windows when I 
have to run our scanner off of my computer (I failed to research which 
scanners are compatible with Linux when I purchased one).

Since Jeff will sooner or later jump in to correct me, I'll correct myself
before that happens:

I didn't meant to say that globals are calculated at compile time -- they
can certainly be modified during runtime.  What I meant was that initial
values of globals have to be calculated at compiletime -- due to the way
they are stored in memory.

Local variables will also be calculated as much as possible during
compilation (like all the literals will be precalculated), if you have a
decent compiler.

When I wrote this, I was actually thinking of literals.  On some
systems, you can silently write over literals, like this:

   int main(void)
   {
  char* s = "Hello";
  *s = 'J';

  printf("%s\n", s);
  return 0;
   }

On Linux, it won't let you do that, but on SGI (O2?) it very smoothly lets
you overwrite the literal.  This is normally not a problem (besides the
bad style), unless the literal space (often stored in the code space) is
shared between processes...  Then it becomes a security risk.

You *can* overwrite non-global const variables under x86 Linux...
apparently :)  It makes sense, since they go on the stack (turning one or
two words on the stack into read-only memory is inefficient from the
hardware standpoint).  It segfaults if you try to overwrite global
constant or static constants, though (global constants are pretty much
like literals, and static variables are pretty much like globals...)

i'm not sure if anyone here has been playing around with tgmath.h, but
here it goes:

   #include 
   int main(void)
   {
long double complex a;
a = 4.0L + I*2.0L;
return 0;
   }

does gdb not have support for tgmath or am i trying to print a complex

well, i'm really talking from a practical standpoint.  my answer
would've been much different if steve had been in academia, especially
the sciences.  a good acamedician NEEDS to know latex for sure.  most
physics journals (most science journals?) make you pay a publishing fee
unless you submit your paper in latex format.  it's the way most scientists
communicate (not soft science.  i don't know if bio people use it
either).

but for someone who wants to write docs, and may want them in a whole
bevy of formats, i think docbook is really the only logical choice.
latex can eventually turn into all those formats too (except for
docbook, of course) but needs external agents.  docbooks' self
containment is impressive.   docbook is very popular right now, and i
have a feeling that its popularity is just going to grow.

Maybe vi-users get their fingers hurt, but psgml-mode Emacs-users
have a plethora of key-sequences which make the job much more
palatable.  Tag-name autocompletion, automatically end-tag, etc.  My
favorite feature is that if you tell psgml where to get the DTD from,
whenever you tell it to insert an element it automatically adds any
attributes or elements that you need to fill in.  For instance, if I
type "C-c C-e section RET" (to use emacspeak), I'll get:

  



  

With my cursor at the title element, ready for me to type in a title.
If I type "C-c C-e link"

Then I'll get a query for the value of the mandatory "linkend"
attribute, and then:

  

Saves a lot of typing.

Might want to look into Blatte, which was actually written by a new
coworker of mine (works in my group).  It's basically a programmable
shorthand language which is converted to HTML.  Easy enough to adapt
to SGML or XML in general, I should think.

With the Emacs functionality I described, it's not a problem.
Especially since if I have text I'm constantly using, I can write an
entity to save myself typing:

  Foo::Bar">

 And then I can just use &foo-class; instead of all that stuff.

No real argument here.  Of course, an extremely well-designed DTD
could give you this same power, but DocBook doesn't have the same
level of detailed power control.

I'm surprised at your conclusion.  What reasons were those?  From my
perspective, I didn't think that any of the reasons I offered were
very strong advantages over LaTeX.  And the loss of direct control is
usually a very big deal to me (somehow not big enough in this case, I
guess).

Hmmm.

Jacks:
Yup, Radio Snack had *some*, but I agree, the best selection was OSH or 
Home Depot. If you have CAT-5 wire, you could use a multi-purpose insert 
with 110-type punchdown blocks, you know, the tiny inserts like the newer 
flush wall jacks at UCD?

http://www.electronichookup.com/keystone%20jacks%20and%20plates.htm

And a color pinout scheme:
http://www.onepassinfo.com/bgtt/rjinfo.asp


Boxes:
Did you want a surface-mount or a flush-mount with a plate over it?

There are single-gang boxes that have medium-sized metal flanges that stick 
out to the sides, and, somewhat like a spring-bolt, they stick out and 
tighten to the inside of a wall.
Not sure if this one can be removed (and all parts saved); like a 
spring-bolt, you might lose the flange if you loosen it.

There are also the regular single-gang, flush-mount with tiny top & bottom 
ears (plastic if you get the blue non-metallic) or metal ears if you get a 
metal box. This kind can be removed rather easily for repositioning. 
Non-metallic are easier to work with.

C isn't C++ - this would work fine in C++; however, in C, "const"
doesn't imply that the variable can be used just like a literal
constant.  It's only a means of telling the compiler that you promise
not to change it.

This isn't an issue when they're defined locally, since non-static
initializers don't have to be constant-expressions.

just small note:

on one of my overclocked machines, i get constant APIC errors.  they
aren't fatal; just an annoyance.  they can rapidly fill the kernel ring
log buffer.  i'd say in 2 days, easily.

also, an oft run daemon or program that tries to get kmod to load
something like NLS can really fill up your ring buffer too!   this
machine currently suffers from that.  i've been so busy that i haven't

Oh wow! I have this head rush like something profound or logically void
was just encountered!

We should ask the Buddah what it means when I say:
"I answered the unasked question."

Perhaps the response from the Buddah would be:
"Uhhh huh-huh. You suck. Stop, like working so hard when you dont have
to." 

Oh wait, that was a channeling from "Butthead". Sorry, I was at least in
the B's. (heh-heh, oh yeah! That was like cool and stuff.)

Again, sorry for not paying closer attention to the question you had. I'll
sentence myself to cease posting for 5 days. ;-)

Yeah, I'm using C++. I didn't realize there was much difference syntactically, 
(besides the 
really obvious features that were added in C++), and I just don't know what the 
differences 
are.

I've never programmed pure C -- I've understood OOP since before I even started with 
C/C++, so 
I always used iostreams and classes. I couldn't use printf to save my life.

dmesg can report kernel boot information (including hardware
detection) unless your machine has been on a while , or something has been
logging stuff for dmesg to cause the older stuff to be wiped out.

You can think of the data available to dmesg as being limited for being
over-written as new data comes in. Immediately after a boot, assuming
other things are not complaining, dmesg should show you good detailed
information about your hardware.

Perhaps you have more wrong with your box. Check out 
# dmesg |more
and see what you have. 

A properly configured server which has been up for 175 days, has so little
reported for access with dmesg, that I can see to the top of where my
kernel was just starting to load. (And this is a busy web server.)

(Have had other servers with >300 days of uptime that also allow me to see
the top of my dmesg data from boot >300 days ago.

To have so quickly lost much of your kernel reported messages from your
dmesg output, suggest you may have some kernel problems, or maybe some
very verbose bits of code loaded in/by your kernel.

Sorry that I misunderstood the problem.

dmesg is very cool. When you system is well configured, you can have dmesg
called shortly after full boot to store your kernel boot info into a file
instead of trying to use your scroll back buffer for your tty and gdm to
copy and paste into a file, or copy by hand this data.

Also, it can help you to identify potential problems or a misconfigured
kernel or module. The man pages for it are short on my system, but
describe what it is for.

why not just look at /var/log/messages[1]?  the kernel "ring buffer" is a
ring.  it can wrap around, especially if useless messages like "can't
find module NLS23423" get logged constantly.

dmesg is a VERY valuable tool.  but just like a saw and hammer, it's
only useful if you know what it is and how to use it.  i think you
should look at man dmesg; you probably have the wrong idea about what it
does.

if you want to know which ethernet *module* got loaded, do lsmod.  if
the ethernet card is compiled directly into the kernel, you can go go
poking around in the symbol table, but the easiest thing to do is to
just look at /var/log/messages.

if you just want to know if the ethernet module is doing its job, just
do ifconfig.  it's nearly impossible for a module to load and not detect
teh hardware correctly.  i've seen it happen, but boy is it rare.

pete


[1] use this.  it'll find the last occurance of 'eth0':

# vi /var/log/messages

do you have a more thorough piece of demonstration code for what you're trying to do. 
Both of 
these pieces of code, as written, should initialize K and ratio to the value of 2.0, 
and 
should both do so without compiler warnings or compiler errors. (I may be wrong, 
assigning 
2.0L to a double in any circumstance may cause warnings to be emitted. Try just 
assigning 2.0)

However:
/BEGIN
extern const double ratio = 2.0L;
extern const double K = ratio;

int main(void)
{
return 0;
}
/END

is illegal, because the extern declaration implies that the variable has been defined 
in 
another file.

also, putting another assignment statement like K=4.0; right before the return 0; 
should be 
illegal in both cases.

The best way to do what you want to do is to set up your ssh to listen on port 23, 
which 
normally hosts telnet. Then, you can use `ssh -p 23 your.host.com` and connect through 
the 
open telnet port. Most Windows SSH clients also have boxes into which to type an 
alternate 
port for an SSH connection. You can change your startup call of sshd to use its -p 
option so 
that it listens on port 23.

Tunnelling over HTTP may also work, but may require more sophisticated tools. Telnet 
by its 
nature should go directly to whatever its destination because the concept of telnet is 
that 
you're typing at a remote computer and it is typing back. HTTP on the other hand, may 
go 
through a proxy.

I find that it's also very convenient to have a web server running on my box, for the 
purpose 
of serving up a Java-based SSH client that I can use when I go to a computer lab that 
doesn't 
have SSH installed.

Re: [vox-tech] Questions about building my own box

2002-01-17 Thread Marc Hasbrouck

As a side note, keep an eye on star office. It
currrently (v6) is trying for that great office suite
position. I have yet to try it and see if if meets the
mark set by MS Office and such, but if it does or even
comes close, it'll worthy of your consideration.

On another note, being the cheapskate I am, if you
have an ols system hanging around, like a PII or
Celeron 300+, Linux will make a dandy workstation.

As was said in earlier messages, the AMD chip gives
you more bang for your buck. Intel is good, but you do
pay a premium for it.

If you're looking for a system to not be too obsolete
in three to five years, buy the fastest thing you can
afford and fill it it RAM. That way, nearly anything
should run. If you are on a budget, take a look at
Rod's website. His prices are in line with anyone else
that'll build a custom system and support it.

It you want to build it yourself, well let's say
that's one of my hobbies. That and doing it on the
cheap. I don't think I'm the only one in LUGOD that
builds their own either. I'm in the Sacramento area
and can make time to chat face to face over hardware,
etc.

I didn't say I had a problem with my network card, I just said that `dmesg` didn't say 
anything about the card. Perhaps you missed it when I said that this ethernet card 
that 
`dmesg` didn't report was the one I was using to post my response to the list. So the

lies, what good is the `dmesg` test if it doesn't report a card I know to *is* working?

Re: [vox-tech] C question: global vs local const

2002-01-17 Thread Mark K. Kim

You're initializing K with a variable.  Because globals are calculated at
compile time, you cannot have variables in the initialization of globals
(since a variable's value is not determined until runtime).  And yes,
const variables are still variables, and const variables are overwritable
under certain architectures by indirectly dereferencing it (but not on x86
Linux).

heh.  i consider myself a docbook "layperson".  i know enough to use it
effectively, but not enough to really understand all the terminology and
"bit's and pieces" of docbook.

as a layperson, i definitely defer to micah who seems to have attained
guru status in this area.  from my own POV, here are some comments for
other laypeople:

1. docbook hurts the fingers.  whereas latex users can talk about

   \url{http://slashdot.org}, {\bf vmlinuz} and {\it important stuff\/},

   docbook users talk about:

   http://slashdot.org,
   vmlinuz and important stuff

   god forbid you write a paper about something like
   dosemu, and you have two choices:

   
   Carpal tunnel syndrome.
   Make good use of vi
  macros.
   

   compare with:

   \begin{enumerate}
\item Carpal tunnel syndrome.
   \item Make good use of {\bf vi} macros.
   \end{enumerate}


   it may look like a small difference now, but write a 10 page
   document, and you're talking about a significantly higher typing to
   content ratio.
   
   docbook is painful.  with a good knowledge of emacs or vi, it's less
   painful.   but it still hurts.   :)


2. for the average latex user, docbook is a loss of control of format.

   for me, the HYPER use of content based markup is a double edged
   sword.  i know you can modify stylesheets.  but danged if i know how!
   it doesn't look easy.  with latex, i can control the location of
   every single dot of my document.  and sometimes latex isn't happy
   about the choices i make,  like under/overfull hboxes and vboxes,
   pictures that don't "float" well, i can ALWAYS force the issue.


ok, that being said, my recommendation is: if you have a choice of latex
or docbook, definitely pick docbook, hand's down.  micah's reasons for
using it are much more persuasive than my reasons for not using it.
and the fact of the matter is, i do use docbook, grudgingly.

All good.

The main reason is for writing Linux how-to's for my own amusements.  Learning this 
looks like it'll be useful.  The ability to convert the same set of text into a 
roughly parallel set of documents in txt, rtf, html (one page or menu'd) and pdf s 
appealling.  

Mainly in that when I write a set of documents for a job (generic how to, etc) I'll 
have a source that is easily convertable (not in MS WORD) and easily updateble.  I 
know that tehre are some VI(M?) plugins that allow this and EMACS as well.  One of

That could be good.  But it'd probably need to include some overview
on SGML, DSSSL, XML, XSLT, XSL-FO, Norman Walsh's stylesheets,
OpenJade, Xalan, FOP, PassiveTex, and maybe a little SVG.  Actually,
if I talked on just the variety of options you have for processing
tools, and left the DocBook format itself for another talk, it might
be possible to give a broad overview of those things.

If people are interested in learning more about DocBook, allow me to
make the following introduction to it.

I love DocBook.  I also love TeX (but am somewhat less comfortable
with it).  I think that XML/XSLT and TeX cover roughly the same niche
in terms of document publishing, and either one can be used as tools
of approximately equal power (though of course XML/XSLT covers a much
broader range than just document publishing).  Since many more
UNIX/GNU/Linux users are already familiar with TeX (especially in
using the LaTeX package), that is probably more often the ideal
documentation tool for many people.  My personal chocies have led me
to prefer DocBook.

The biggest differences in my mind between DocBook and LaTeX, are:

1. Both are considered to be "content-oriented", versus word
   processing or desktop publishing which are considered
   "format-oriented".  In actuality, though, LaTeX is a
   *pseudo*-"content-oriented" high-level wrapper around what is
   really a "format-oriented" typesetting language (TeX), that happens
   to be powerful and flexible enough to allow you to be
   "sort-of content-oriented" when you want to be, due to the fact that you
   can wrap low-level functionality in high-level packages.  However,
   at any point in writing a LaTeX document, you can immediately drop
   down to "low-level" again, writing in pure TeX commands.  But even
   when you're dealing with LaTeX-only, there are many elements to it
   which are decidedly more format-oriented than content-oriented -
   i.e., there is nothing content-oriented at all about using /hfill
   or /vbox (or whatever they are).

   In contrast, DocBook really *is* purely content-oriented.  DocBook
   has no mechanism for describing formatting at all - only
   content-oriented markup describing what a thing *is*, not what it
   looks like.  This is not necessarily a good or bad thing - it is
   simply a distinguishing point.  All formatting is described by a
   totally seperate document - the stylesheet driver, with which you
   specify exactly what you want the DocBook elements to look like.
   There is no point in a DocBook document at which you can "drop down"
   into low-level format-oriented stuff like you can in LaTeX -
   instead, you use the appropriate element, and edit your stylesheet
   to format it how you like it.  This has the advantage of forcing
   your document to be highly structured, but it has the disadvantage
   of placing your power-of-formatting under the flexibility of
   DocBook (or whatever DTD or Schema you use for publishing).  If you
   want to get a particular formatting element into your document but
   DocBook doesn't supply an appropriate element of which you can take
   advantage in your stylesheet, then you are out of luck.  If you
   needed that element sorely, then the best thing you can do is make
   your own DocBook-like DTD, and invent the element you're lacking.
   There's nothing wrong with doing this - and so you're never really
   constricted in what you can do format-wise with XML/XSLT; however,
   once you go outside the realm of "pure" DocBook, you can't expect
   other people to take your XML or SGML as-is and do stuff with it
   unless you also pass around your DTD and your stylesheets.

2. I consider XML a more universal language of expression than LaTeX
   or TeX.  Not that TeX isn't available on pretty much every platform
   that matters, but XML is in much more widespread use outside the
   realm of UNIX.  Also, XML is "newer" than TeX - although it's
   really a redesign of SGML, which is about as old as TeX (don't know
   which is older).  DocBook is available in both XML and SGML, and
   has itself been around for some time (but not as long as TeX), so
   this is a somewhat flimsy argument :)   ...but mainly, XML (in
   general) has massive attention right now, in comparison with TeX,
   and so various XML-related technologies are cons

[vox-tech] C question: global vs local const

2002-01-17 Thread Peter Jay Salzman

when ratio and K are defined externally, gcc complains about a
non-constant initializer:

   const double ratio = 2.0L;
   const double K = ratio;
   
   int main(void)
   {
  return 0;
   }

however, when defined as local variables, there's no problem.

   int main(void)
   {
  const double ratio = 2.0L;
  const double K = ratio;
   
  return 0;
   }

why isn't const being honored for the global variable version?

I agree with you, but I haven't found a word processor that does better

Well... maybe WordPerfect 5.1.  But it has too many shortcomings, like a
lack of GUI, WP-specific printer drivers, etc.

[La]TeX is great for typesetting.  For more visual-oriented documents,
though, [La]TeX isn't the way to go.  Like if I wanna make a
pretty-looking table or putting things in alignment.  For those tasks, I
still use word processors, which means booting into Windows for Word
because I don't like any of the word processors on Linux.

I still like IE the best.  The last version of Mozilla I tried was way too
slow for my taste (though I was probably using a version with debuging
turned on.)  Netscape is not very good.  Opera comes pretty close, but
there are too many things it can't do, like Flash plugins (I'm waiting for
6.0 to stabilize!) and the controls are a little querky, too.

I'm with you there.  I use Outlook at work, and I can see how people might
like it, especially with PDA syncing and stuff.  I think the information
is too localized on Outlook (or any similar program), though -- I like to
be able to access all my info from any computer with Internet access.

Ahh yes. This is/should be supported. The 3c905 are covered with the linux
modules "3c5x9"

(Pulling from the Kernel Configure.help in /usr/src/linux/Documentation
and jumping to the right section)
--- [ start - copied from anotehr doc as cited]
3c590 series (592/595/597) "Vortex" support
CONFIG_VORTEX
  If you have a 3Com "Vortex" (Fast EtherLink 3c590/3c592/3c595/3c597)
  or "Boomerang" series (EtherLink XL 3c900 or 3c905) network
  (Ethernet) card, say Y and read the Ethernet-HOWTO, available via
  FTP (user: anonymous) in ftp://metalab.unc.edu/pub/Linux/docs/HOWTO.
  More specific information is in Documentation/networking/vortex.txt
  and in the comments at the beginning of drivers/net/3c59x.c.

  If you want to compile this as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want),
  say M here and read Documentation/modules.txt as well as
  Documentation/networking/net-modules.txt.
--- [end]

This is the modules you will likely need in order to have your
"eth0" interface be used wit the 3com card mentioned.

To see if it is loaded (I dont expect it to be listed) try
# lsmod

If you see "3c59x" in the list of loaded modules, then we have a different
problem entirely. (Please say if you see this module loaded right now, and
we can follow that route. For now, I will assume it is just not yet
loaded and the instructions below can be followed.)

Assuming "3c59x" is not loaded, we can load it plus and modules that may
depend upon it with:
# modprobe 3c59x

(It may be "# modprobe 3c59x.o" It has been a while since I used it, and I
am not sure if the ".o" is assumed. If the first gives an error, thy the
one with the ".o")

Since it is a card that I have used before, experience dictates that you
should not need to hand any arguments. (There are always exceptions! ;-)

After you issue the above command, then try this:
# ifconfig eth0

If you see information about the interface like ethernet address, etc. You
can try this command:

# ifup eth0
(Assuming RH has this like Debian) To bring up the eth0 interface with the
configured settings you included before. (of course "# ifdown eth0" would
bring it down.)

Now try to ping your gateway
# ping w.x.y.z
(Where w.x.y.z is the ip address of your gateway)
(To stop the ping process, you can press control-c)
(Positive results would include one line each second being printed with a
measurement in latency in milliseconds (ms) for responses to the gateway)

If you can ping the gateway, then try using netscape, or some other tool to
use your networking.

If networking works, then you should make sure this modules gets loaded
upon each start of your system. To do this, edit /etc/modules and near the
top (after the comments) add "3c59x" (no quotes) on one line by
itself. You may want to test that you network comes up on reboot by
actually rebooting your system, though you do not NEED to reboot if you
dont want to verify this.

After the module is loaded at start, you should expect your system to
automatically set up and "up" the interface for you. All of the above
commands are really for troubleshooting, and would/should likely not be
needed once your system is completed with networking setup.

lspci reports on PCI devices attached to your system, but not all devices
are *necessarily* configured to work with linux. This is kind of like
going to the Windows System control panel and looking at the devices, and
seeing devices that are installed but are not working (Exclamation marks,
or question marks.)

As a fun thing, if your card is recognized by the OS ("ifconfig eth0"
reports good info) try doing:

# cat /proc/interrupts
and you should the IRQ used by the enthernet card (will be next to the
entry with "eth0" or on the same line)

# cat /proc/ioports
and you should be able to see the io ports used by the ethernet card (next
to eth0 or on the same line(s).

I believe that you will only see the IO ports and IRQ of devices in these
proc-special files when the OS recognizes them - am not completely sure,
so if someone else claims otherwise, they may be right.

I frequently dump this data into a a text file on another system (as well
as other useful bits) just in case I need to know information about a
machine that has just had a serious hardware failure (SCSI Card blow-out
for example.)

Please let us know if the above works, or does not and where there are

Seriously, if it's confusing, don't use .mozconfig - just hand the

just print out ./configure --help to find out what the options are.

Not a chance.  For a long time, I had lamented that there were no
browsers even *close* to comparable to MSIE.  Now with recent versions
of Mozilla, I lament no more.  In fact, I even prefer to use Mozilla
on my Windows machine.

Outlook I've never missed.  Never liked it much anyway, and mutt, or
emacs' rmail-mode, offers me the ability to read my mail without
reaching for the mouse (which can be annoying).  However, if I *did*
miss Outlook, I'd switch to Evolution - in fact, I am experimentally
switching anyway.

However, that Mozilla and Evolution have "stolen" so much from MSIE
and Outlook are testaments to their solid GUI design (despite their
crappy security, etc.).  So obviously, those are some of MS's good
products.  But better ones now exist.

As to Office - I haven't used a Word Processor in a couple years.  Not
nearly enough power to 'em.  Sure, the interface is convenient, but
it's *power*, not convenience, that I crave - and for that, the choice

privacy laws is about as relevant as asking him to go read a book on

On USENET (particularly technical groups like comp.lang.c), most
regulars even have the presence of mind to not post email that has no
purpose other than to rant and insult and unjustly accuse.  They
simply state that this is the case, and offer to prove this is the
case if the author will give permission to post the email (placing the
ball squarely in the offender's hands)

There is a huge difference between email privacy and this.  This is
often considered a possible breach of *copyright* law, since
permission wasn't given to republish the letter (this is more of an
issue in more public forums, such as USENET).

Regardless, it is plain indecent.  It has little to do with law, and
everything to do with netiquette and just plain moral common sense.
Your argument about email privacy is completely irrelevant, IMO.

I finally sat down at the little box and poked around.  I noticed
when I ran "/etc/init.d/ssh start", it didn't say anything.
Examining the script, there seems to be something new... this test:

Removal of the said file and re-running of the init-script worked,

agreed.  however, if you get a bleeding edge board, you may often have
no choice to upgrade the CPU.  the 266MHz FSB boards that came out about
6 months ago won't be able to support the new athlons that are going to
be released soon.  this shouldn't stop you from getting a bleeding edge
board, though.  power is fun.  i also don't see the need for more than
my 1.4GHz, 266fsb, ddr athlon for a very long time.

OTOH, those of us who bought the 440BX boards many years ago saw the
pentium II inch its way up to (what was it, 450MHz?) before a
motherboard chipset upgrade was needed.  that technology lasted a
lng time!  i don't think we'll ever see anything like that again.

months ago, support was shady for the newer athlon stuff.  agp was non
functional.  it all fell into place with 2.4.10.  at this point, there
aren't really any issues i'm aware of.

also -- athlon hardware is ... well, for want of a better word,
"cranky".   i tore my hair out trying to figure out why my system
wouldn't work.  turns out that you need amd approved cpu heatsink/fan
and amd approved power supply.   and they really mean it!  if you go
with amd, definitely do the research on what products are approved and
stick with it.

nothing sucks worse than having a non-functional system in front of you
and having no idea whether the problem is the cpu, the memory, the power
supply or whatnot.  it's SO much easier diagnosing non-functional
hardware when you have a similar functioning system sitting on the next
table...

well, it doesn't kill -- it maims pretty badly.   :)

one tip: there are so many online places, don't buy from any company
that doesn't have a "satisfaction guarantee", like tigerdirect.com.
don't patronize places that won't give your money back if you're not
happy with the merchandise.  it's a buyer's market, not a seller's.

agreed, except if you have a system you can cannibalize for peripherals,
it might be cheaper to roll your own.  your video card can be 1/4 of the
price of the whole system...

also - don't spend too much money on sound cards.  i've had many of them
in my life, and i honestly can't tell that much of a difference between
any of them.  speakers seem to go a longer way than sound cards...

Ok,

Here's the base generalization.  You want the most bang for your buck, figure a 
minimum of 3 years before you can afford to upgrade again.  Do not skimp on the 
motherboard, that often determines the feasibility of later CPU only upgrades.  ASUS 
makes good boards that have long life due to BIOS updates, but there are several 
others.  I have had good luck with AOpen, ABit, ASUS and Shuttle.

AMD seems to have the best price/performance deals right now.  If you are going to 
build it yourself, assess your skillset and available help, and go for it.  It is the 
only way you will learn how to do this.  If Linux will be on it, 'MOST' new stuff will 
actually work with it, those on this list can steer you around most known issues.

I buy my stuff from Fry's or online, depending on whim and where I am when I decide to 
buy.  www.pricewatch.com for online stuff.  In general, costs of shipping kill any 
savings gained from buying online, though deals are still to be had.  Buying local has 
the advantage of faster return.  Oh yea, don't believe anything the Fry's guys say, 
they range from correct to wildly wrong.

Last, it is generally more expensive to build your own.  BUT, you are generally 
building performance systems when you do that.  Pre-built systems make the compromises 
for you, but by examining their secs, you can determine if they are compromises you 
can live with.

I have found that some of the Home Depot have a decent section of connectors/mounting 
plates for a wider variety of A/V hardware then I had previously believed.

The one in Elk Grove has most of an aisle with everything from Ethernet hookups, 
sterio wallplates and phone testing equipment.

If you are going to put a box in, you want to go for a 'remodel' type box.  You would 
generally cut a hole 'just' big enough to slide the box in.  It then has 'ears' that 
swing out to anchor it to the drywall.

Because I sometimes need to get at stuff at school ( but can't because I 
dont's use anything with cleartext passwords ), I need to encapsulate an ssh 
connection over either telnet or http.

Use keypairs already, I like them.

Graybar (www.graybar.com), but you need to know someone with a
wholesalers licence. They have a comprehensive selection. There is one
in Sacramento off of 80, Arden exit, I think.

(Please dont think I am being condescending here. I try to target
information for not the the informed but the uninformed who might also be
reading along with you.)

Note the above is missing the "eth0" interface?

In many x86 Linux systems, ifconfig will report all activated (up)
interfaces when you run it without arguements. The above suggests that
"eth0" is not really activated at all. (One of the reasons I suggest these
commands be run.) (lo is a loopback interface, or a pseudo interface to
allow the computer to "talk to itself" over a network without sending any
network traffic to a wire. As a side note, you can ping 127.0.0.1 and see
responses even though those pings are not going to a real netowr wire.)

> [root@penguin /root]# ifconfig eth0
> eth0: error fetching interface information: Device not found

Ah. An explicit call to ifconfig this interface produces these
results. This strongly suggests that the ethernet card has not been
recognized at all by Linux. Either the driver has not been loaded, the
driver loaded for the card has problems or, the card does not work with
Linux with your currect configuration of kernel and drivers.
(I am sure there are other possible reasons, but these include about 96%
by experience.)

Now it appears to be a driver problem. (Good start to identification)

Who makes your ethernet card?
What is the model?
What IRQ and IO ports does it use?
Is it PCI, EISA, ISA, or?

(If you need help with the above, we can prompt you with more specific
information on the questions. Acronyms and abbrevions used can sometimes
be foreign when you are unfamiliar with them.)

If you have Windows running on this box, you can try booting into windows
and seeing what the name and model of the ethernet card windows says you
have as well as IRQ and IO ports.

Look at the originbal computer information to see what model ethernet card
you have.

If it is a PCI based Ethernet card, you can copy and past the results of
# lspci
and we might be able to find out answers to the above.

Knowing the model, vendor, IO ports and IRQ are some key things that many
of us can likely use to help you get the card recognized. (Sometimes they
are needed to tell Linux where to find the device for which the driver is
being loaded.)

Once eth0 is recognized, we can proceed with the rest of the items (that
will likely just "work" with very little more work.)

Another thing you can try (if you want) is this:

# dmesg | grep eth
If you just see another:
#
Then that suggests no eth interfaces were found by the starting
kernel. (What I expect you would see.) 

If you see a result that includes the word "eth" followed by a number
grater than or equal to zero (e.g. eth0, eth1, eth2) then we have a very
interresting problem indeed.

If after getting your hardware to be recognized there are stil problems,
we can look to ipchains or network filters or physical wiring errors.

here's my analogy... :)

If Johny turns to you in a class you particularly enjoy and says
"This lecture is boring, the professor doesn't know how to captivate the
class." you wouldn't stand up and yell out "Excuse me everyone, Johny thinks
the professor is boring. What do you all think about this?"

The situation may be different, but the same principle applies. Conversations
that are taken out of list scope are taken out for a good reason,
they shouldn't make their way back to the public because someone wants to
bitch about getting their wrist slapped.

All mailing lists are meritocracies. They all have their Alan Coxs and their
Jeff Newmillers :) When I read vox, the first threads I read are the ones
that have posts from people I know have something to contribute, or are
on a subject that I feel that I can make a contribution to.

It comes down to a simple point, IMHO vox-tech is a place to come to for
when you know something, yet you need a steering, a recommendation, a sagely
ear. It is _assumed_ that you have already done your research before posting
here.

I consider vox-tech to be... of a higher level than vox. The traffic tends
to be more informative, the posters are generally more educated.
It is no place for elite sarcastic remarks, no matter how much more
informative the post may be.

Absolutely. He's there to make our reading more enjoyable as a whole.

I disagree, I think it goes into the realms of respectfulness. The list
maintainer is there to make sure we don't abuse the list, or each other.

I agree. I think this is were "common sense" kicks in. But I also think that
as the elected (or, unchallenged perhaps) list maintainer, Pete has the right
to pick out what is obviously inappropriate and warn the poster.

I really like the way vox/vox-tech have been for the last little while.
It's not often I think about it, but it's much more enjoyable to post to
readers who'll read my remarks and argue for/against them for what they are,
not using personal remarks to win their points. Whenever a flame war breaks
out, we all end up being neurotic and over analysing every period, terminating
preposition and split infinitive in each other's posts ;)

an excellent move. I can't stress the convenience factor of being able to

Sounds like you might be looking at one of the many uses of ssh :)

I'm not sure what you mean. How do you want to access your data?

You might even want to look into authentication key pairs, if you're using
a laptop or some private system. This will make using scp more convenient,
as you won't have to type out your password all the time. It's kind of
annoying when using CVS over ssh to have to type your password at every
commit/update.

Ssh can do encrypted port forwarding. I've used it as a proxy from isun to
home so that i could check out my webserver from the outside.
You should be able to forward just about anything over ssh though.

The man page goes into some detail on port forwarding and key authentication.
That is always a good read.

Have you tried serching freshmeat for a VPN package?
I see several hits, including one that encapsulates tcp/ip.

You might be interested in running Evolution (it just hit 1.0 a couple of
weeks back). It is supposedly very Outlook like, with that being it borrowed
