Lose the '.class' suffix;

Subject: Is it possible to copy a Red Hat CD on a Windows system?
Date: Tue, 8 Jun 1999 09:40:34 -0700
I bought a CheapBytes Red Hat 6.0 CD and I have a friend that wants me to
copy it for him (saves him a little money since he already has the blank
CDs). My problem is that the only CD burner I have is at work and it is on
a Windows NT machine. I am using Easy CD Creator Deluxe. I have searched
quite a bit about creating Linux CDs on Windows machines and everything I
find is really talking about creating one from scratch using downloaded
files (most say it is not possible without using Linux).
The thing I am interested in finding out is if I can copy an existing CD. I
don't know a whole lot about how CD burners work with respect to ISO images
but it seems to me like I should be able to make an ISO image of the
original CD and burn a new one using the image. If I were using Linux I
would trust that but in my experience Windows programs like to "help" you
out without telling you so I was wondering if it would try to convert the
file system to Joliet or if an ISO image is a bit-for-bit image of the CD.
If it were my disc I would just burn one and find out if it works but since
it is my friends CD I don't want to ruin one if I can avoid it.
Thanks for the help,

although the users will be able to view files on the comp in the root (/)

you are likely out of ram and swapping heavily. check with free or

rid of KDE or drop at least another 32MB into your box.

Subject: Problem forwarding syslog messages.
Date: Thu, 3 Jun 1999 10:12:17 +0100
Hi,
I'm having a bit of a problem with forwarding messages from syslog on a
solaris 2.6 box to a linux machine running redhat 5.2
(sysklogd-1.3-25).
What happens intermittently is that when two messages are sent out of the
solaris box, with the same facility.level code, and the same text. The first
occurrance is sent to the linux box and Solaris seems to hang on to the
second to see if it will be repeated more times. When a third message comes
along that is different, the second message is sent as "last message
repeated 1 time", and the third message is also forwarded.
Syslogd on the linux machine now gets into a bit of a problem, repeating the
third message over and over, and repeating the "message repeated 1 time" as
well.
E.g. Using the following commands:
logger -p user.warn "test"
logger -p user.warn "test"
logger -p user.warn "test2"
would produce :
May 28 16:56:10 solaris1 soluser: test
May 28 16:56:10 solaris1 last message repeated 508 times
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time
May 28 16:56:15 solaris1 soluser: test2
May 28 16:56:12 solaris1 last message repeated 1 time

Subject: Undeletion help!!!
Date: Tue, 08 Jun 1999 17:43:52 GMT
I have a RedHat 5.2 system running as a samba
server for my home. My wife had a backup of her
entire system on it which she recently deleted off
of her home directory. She just had a hard drive
crash and I now need to get the stuff she had
deleted back onto the Linux box.
I have done some preliminary investigation trying
to use e2recover and I can see all the inodes that
were deleted. Fragmentation should not be a
problem because the server does not get a lot of
use at all. (I have also since put the /home
partition into read only mode)
My problem is that e2recover will not work with
drives over 2 gig in size, and my drive is 8.4
gig. When the program runs it gets a FUNC_SEEK
error. (Apparently the FUNC_SEEK error has
something to do with the fact that whatever
underlying function this e2recover script relies
on cannot access inodes past around 2 gig) So
what I need is any help in trying to get e2recover
to work with a larger file system, or a similar
program that works with larger drives.
Any help that anyone could give would be GREATLY
appreciated!

refuse the winmodem.
i'd go down to the local <ethnic>-quarter and get a small shop to
build a system. you can tell them exactly what you want and they
build it for you. go generic and basic.
i really like the small shop approach. they use straighforward
motherboards and cases.
do not get weird motherboard built-ins like video or sound. built-in
usual stuff like ide and serial is ok. on-board scsi has given
problems in the past but may be straightened out now. get a lot of
pci slots. get an external serial interface modem.
bundling is a way to sell one good item and foist a lot of substandard
stuff on you at the same time. this is how the big pc houses make
money. the 500MHz PIII with winmodem is a classic example of this.
if you do not feel comfortable with specifying your own system,
there are several linux system vendors. they will build you a
complete system with linux pre-installed. you will be confident that
all the hardware works with linux.
if you feel bold and strapped for cash, go to a computer show. buy an
obsolete pentiumpro based system and fill it with ram. a ppro 200 is
still fast and the prices are really low. you can even get a dual
system for not a lot of money.

Date: Tue, 8 Jun 1999 20:40:35 +0200
Hi !
I've managed to get my ISA PnP AWE64 work correctly, except MIDI :
- I found that the default MIDI port was the external one => Can't get a
sound to my speakers ;
- I can load manually awe_wave => The internal MIDI port come in memory (=>
Sound OK),
but this mod do not load automatically (even with drvmidi) as others
modules.
Could anybody explain me :
- how to make it undestand that I want on demand awe_wave loading ?
- how to get the internal MIDI port as the default one ?
- and more generally, how do the kernel know wich module to load and when ?
I could use modprobe at startup but I feel that I missed something (why
*this* module is not on demand
loadable).
Note : I use SuSE Linux 6.1, recompiled 2.2.9 kernel (with egcs) with kmod
support (no more kdaemon).
There is a link /dev/midi -> /dev/midi00, and the internal port seems to be
/dev/midi01 (/dev/midi00 loads
the sb module).
Thank you very much...

Subject: Renaming Files
Date: 8 Jun 1999 11:01:57 -0500
I was assigned a relatively easy task of taking Dos filenames and
uncapitalizing them for easier use in Linux. (You know that when take a
file and transfer it from DOS to Linux it capitalizes everything). To my
suprise in my debugging phase I found that could rename ANY file even if I
didnt have permissions to the file (no...I was not logged on as root
either....or even as "su"). Does this sound right that you can rename any
file you want?? Seems to me like that would be a big security hazard. If
anyone can tell me what is going on there like if that is what should be
happening, or if I should not be able to rename the file, it would be
greatly appreciated. Thanks in advance for any replys!

Linux will run fine on it (slow, but fine). For X-Windows you need at
least 16 meg, preferably more. Memory is somewhat cheap, so a memory
upgrade is a Good Thing(tm). Also, you'll want a bigger hard drive,
again hard drives are cheap enough. Don't worry about the BIOS not
supporting a 'large' drive. So long as you make a 'small' (64meg) root
partition near the beginning of the drive, things will work fine. Once
LILO loads vmlinuz (with the help of the BIOS), the BIOS becomes a
non-issue. Linux has kernel code to emulate the FPU, so even floating
point code will work (slowly).
This box might make a great X-Term. Drop in a NIC (eg 3Com509) and you
can have a second 'seat' on another linux box.
