I had typos in the last email.
Take your own advice. Reiser 3.6 has a FS limitation of 17,592 (not 17)
gigs (only
b/c of the page cache limits it to that value) and the max size for an
individual file is also 17,592 (not 17) gigs for the same reason. The
extended limit
is actually 1152921504 gigs.
Version 3.5 had the old limitation.

Having written many pages of techincal prose using both, latex,
without a doubt. If you just let latex take care of the formatting for
you, it's extremely simple to use. Just type your text, tell it what
the sections, chapters, and footnotes are, and let it rip. For fancier
stuff, latex does require some self-education, but by staying with the
latex defaults you can delay a good deal of that for a bit.
MS Word has gotten much more capable over the last few years, but at
the cost of requiring ever more time to learn. I've had enough
adventures with MS Word 2000 garbaging my documents that I've probably
spent as much time learning the intricaces of word as I have with
latex. The day I spent learning how to do cool things like having
latex automatically pull in and format bibliography entries from the
online databases felt much more useful and less aggravating than the
day I spent trying to figure out why my 20 page doc required 100 MB.
So to be fair to everyone, both systems are complicated and each will
require some hours of hair pulling and cursing.
A good book is very helpful. I like "A Guide to Latex" by Kopka and
Daly.
Good examples are even more helpful. The comp.text.tex newsgroup
should be helpful there.

You will probably have to make an effort at narrowing your code
down to just that part which is significant in order to find the
problem.
In the process you can fairly quickly determine if it is the
write or the read that is faulty by changing the write process
to write first x number of records, and then 2x (or some other
obviously larger number) where x is greater than the number at
which the fault appears. Check the file sizes after the process
is run, and it is either larger or your write process is at
fault.
In any case, whether it is the read or the write process, if you
narrow it down to the smallest program possible which
demonstrates the problem, you'll most likely discover the cause.
If not, when it is sufficiently reduced you can post it for
others to look at.

This depends on the player you're using. Can't say much, since the only
MP3-CD playing device I have is an Apex 600A DVD player. That device
can deal with subdirectories easily enough, but it does not recognize
RockRidge or Joliet extensions, meaning the onscreen display shows a
bunch of 8-character filenames (yuck). By default, it plays songs in
ASCIIbetical order. Playlist capabilities are nonexistent.
The "safe" way would be to dump all the mp3s into one directory, then
mkisofs -r -J /path/to/that/directory | cdrecord dev=X,Y,Z speed=W -
and call it good. If a player cannot deal with Rock Ridge or Joliet, it
will fall back to 8+3; if it can, it will use the ones that it can deal
with.

bullshit. I can't think of a good acronym, but, Redhat is not GNU. Nor is
Mandrake part of the Vim developement effort, though they chose to release a
Vim alpha version. RH likes to be on the bleeding edge; if they only used
stable versions in their distros, they would be as backwards as Debian. Of
course, the shit might work better, but that's no fun. You wanna run with

I am amazed that the thing would even boot. Perhaps you actually
meant 128 Mibytes of RAM on the Windows PC? 12 Mibytes (let alone 12 bytes)
simply doesn't cut it these days. (-: Or is this the PHB's PC? :-)

You might have to create a batch file to use on the Windows PC (note:
you might be best off using Linux utilities to create the batch file, and then
port it over) to rename the files while copying them (from the mapped drive
letter corresponding for the Linux machine to the local hard disk of the
Windows machine). If you don't fix this, you will have problems no matter
what you do. I don't have detailed instructions for doing this autorename
myself, because I would have to mess with it for a while to figure it out.
But I know that the utilities in Unix/Linux are much more powerful than what
is available in Windows (at least without expensive 3rd-party software, unless
you get really lucky), so experiment on a small sample directory tree until
you get a Linux script to write the Windows 2000 batch file properly, and then
port this over to the Windows PC. If your file transfer mode for the batch
file did not convert LF into CR-LF, open the file in EDIT once and save it to
do this conversion (this at least works under Windows NT 4.0, so I am assuming
that it works under Windows 2000).

Browse the Linux newsgroups for messages about the 2 Gibyte limit.
Basically, the ext2 file system can handle humongous files (2 Tibytes), as can
kernel 2.4.x and certain patched late 2.2.xx kernels, but other programs (FTP,
NFS, etc.) can be weak links on 32-bit architecture machines. If they use
32-bit pointers to memory-mapped files, they will limit you to 2 Gibyte files.
You might want to search for newer FTP software that does not have this limit.

>(ntfs Read is OK, but not write yet).
If you have enough spare disk space, you could have Linux write the
files to a FAT32 volume (using autorenaming as conceptually described above),
and then have the Windows 2000 machine read them from the FAT32 volume or even
convert the FAT32 volume to NTFS in situ. Be sure to do a data integrity
verification in between (perhaps use the same autorename utility that you will
hack together to do the copying also do a diff on the files after you reboot
the machine to clear out all disk caches, if you are really paranoid).
>so, any other things I could try? I have not tried PCNFS. would you think that
>would be more reliable?
I could be wrong, but I understand that NFS is another set of software
that has the 2 Gibyte limit (if I recall correctly, not just on 32-bit Linux
machines), and that a fix for this is still in the future.

couple questions about my ppp connection. i just installed linux for my
first time (RH7). i can get my ppp connection to work when i send all the
commands on one line, but once i attempt to use the generic chat scripts
supplied with RH i keep getting "permission denied" errors, even when i'm
root. anyone have any idea what this is all about? and when i tried to
write my own script i keep seeing "chat script failed" in the /var/log
with no other info. i have the permissions set to rwx for everyone but i
just can't figure out what's going on. I also tried wvdial. it would
establish a connection then hangup
and give an error message saying "not 8 bit clean". I read a
couple of How-Tos and they mentioned the not 8 bit clean error but they
were pretty much no help. i'm sorry if i've left out crutial sys config
info, but any help would be appreciate. iv'e read gaggle of white pages
and i know infietly more than i did a week ago but it seems as though i've
hit an impass....
also, is it possible to find out the ip of your ISP's DNS without asking
them? just curious.

Grr, serves me right. I'm using the 3.5 version and had no idea that
things had been fixed in the latest. 17,592G = 17.1T and I don't know
how many people have that much disk in one partition. Gonna be at least
2005 before that kind of storage space becomes commonplace....

Subject: insmod?
Date: Thu, 14 Jun 2001 03:52:38 GMT
I am happily running on my new kernel 2.2.14, Redhat.
One nuisance still remains - one of my two NIC's, (A Linksys LNE100TX)
doesn't load automatically. Instead I have to do a couple of "insmod"s and
an "ifup eth1" to get it going.
Where do the "insmod"s normally get executed from during system bootup? How
can I locate where the system is trying to do them (if it is even trying),
so that I can solve the problem? I have easily fixed the problem by putting
the "insmod"s and "ifup eth1" into rc.local, but I would rather solve the
problem properly - only I don't know what part of the system is responsible
for doing the insmod, and how it does it.

The 2.4.X kernel is your problem here. Boot from the 2.2.XX kernel and
your problems will disappear.
I installed Red Hat 7.1 on a system which gave the exact same error
messages with RH's 2.4.2 kernel and got rid of the problem by installing a
2.2.19 kernel.
Fundamentally, if you are using legacy hardware then use a legacy kernel.

RMS misses his points on occasion. On some systems it is desirable to
restrict the use of su to members of one group. RMS believes that
