Frank,
I tried your suggestion and got the exact same error message, and the exact
same entry in /var/log/messages:

In case it helps:

Dear all,
I want to do this (in /etc):
cp modules.conf modules.conf.bak
with:
cp modules.conf *.bak
The message is quite unexpected:
<message start>
cp: copying multiple files, but last argument `sysctl.conf.bak' is not
a directory
Try `cp --help' for more information.
<message end>
Can anyone tell me why the wildcarding doesn't work? Thanks.

Subject: extended file attributes
Reply-To: [EMAIL PROTECTED]
Date: 17 Apr 2001 08:58:31 -0500
Curiosity has driven me to toy with the chattr command. The man page
states that the "c mode" will cause a file to be dynamically compressed
as it's written to disk and decompressed as it's read from disk.
To explore this, I attempted to set the "c" attribute on an existing file,
and then check its disk usage (with du). Its block allocation didn't
change (although perhaps it was still compressed--who knows?). Not
thereby discovering anything, I created a new file (with touch), set
the "c" attribute on it, and copied the contents of another file into it;
but alas, the disk usage indicated exactly the same number of blocks
allocated to it.
Is this particular attribute functional? And if so, how is it to be used?

Subject: Printing Question
Date: Tue, 17 Apr 2001 08:49:07 -0500
How do I set up 'form' definitions on Linux (Red Hat) for use when I print
with 'lpr'. When I say form definitions, what I mean is something like
'3h32' which means 3-hole paper, 32 lines of text. This way, I can predefine
certain types of paper and label formats so that when I want to print them
in Linux, everything's in place to do so. I know this can be done in certain
flavors of Unix with tools such as 'lpforms' which allow the creation of
form types that include such things as lines per page and characters per
line. Is there a linux version of the lpforms utility, or are there other
tools out there that can do this for us when we use print using the 'lpr'
command.
Thanks in advance!

Subject: some question about initrd
Date: Tue, 17 Apr 2001 21:59:43 +0800
hi,
I have some question about initrd.
If I have a compressed ramdisk image: initrd.gz put at a memory location
for example: 0x00070000 (in fact, in my application, it is flash)
1. what is the meaning of initrd_start in rd.c (linux-2.4.0)?
Is it means 0x00070000?
or is it means the initrd.gz will be decompressed to the
location initrd_start?
2. How to tell the kernel that I have a initrd who's image
is located 0x00070000?
I saw the Document/kernel-parameters.txt, is seems doesn't
have suitable parameter for me to use.
Should I modify the kernel source code to fit my requirement?
I've saw the "How-To: make root/boot disk", it use floppy's
specific sector as ramdisk image,
I think is's a little similar to my application,
I will try to just specify memory location instead of
reading from floppy's specific sector.
Thanks in advance for you help

Subject: rpmdb -- how to access?
Reply-To: [EMAIL PROTECTED]

There's a package on the RH 6.2 cd called "rpmdb..." which purports to
contain a database of all RH packages in the distribution, such that
it could be searched for package locations of desired dependency
elements. There's also a function of rpm, "--whatprovides", which
can presumably search a database and locate the package that provides
a particular element which some other package has as a dependency.
It seems like these 2 should play together, but I haven't found out
how to make them play. I'm familiar with rpmfind, but that seems to
be only network-oriented.

Suppose there are three .bak files in /etc. Think of what's
happening if you type
$ ls /etc/*.bak
The shell will expand this into
$ ls /etc/foo.bak /etc/bar.bak /etc/buz.bak
and will call the program 'ls' appropriately. Now, if you type
$ cp modules.conf *.bak
this will be expanded into
$ cp modules.conf foo.bak bar.bak buz.bak
Now 'cp' just tries to be smart and assumes that the last
parameter (buz.bak) is a directory, it tries to copy the files
modules.conf, foo.bak, bar.bak into the "directory" buz.bak.
Since buz.bak isn't a directory it gives an error message and
aborts.
Regards.

Make sure that the block size is set to 0 (variable length), using
mt. You can loose HUGE amounts of space to inter-block gaps. If "mt
setblk 0" doesn't work, then you need a different mt. Look for
"mt-st".
You want to use the largest blocks possible, which also means
increasing the default Linux buffer size from 32k to at least 64k.
Read /usr/src/linux/drivers/scsi/README.st and change ST_BUFFER_BLOCKS
in st_options.h. Or use a kernel parameter like "st=64". I haven't
verified the latter, so I may have garbled the syntax.
In variable block mode, the size of the block written to the tape is
the size of the block written by the application. I don't use dump,
and don't know if there's an option for that. With tar, use the
Solaris default blocking factor of 127. For example, "tar cvbf 127
/dev/st0 /home". The "b" parameter is the number of 512 byte blocks.
I have gotten 2.3GB using tar, so dump should be able to do it.

Subject: partitioning woes again - RH6.1
Date: 17 Apr 2001 14:19:36 GMT
I installed a RH 6.1 side by side (was the intention) with a Win2000
installation which was already there.
about 20 GB of a 40 GB IDE disk were partitioned like the following:
The number of cylinders for this disk is set to 2501.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Kommando (m für Hilfe): p
Festplatte /dev/hda: 255 Köpfe, 63 Sektoren, 2501 Zylinder
Einheiten: Zylinder mit 16065 * 512 Bytes
Gerät boot. Anfang Ende Blöcke Id Dateisystemtyp
/dev/hda1 * 1 65 522081 6 FAT16
/dev/hda2 66 1226 9325732+ f Win95 Erw. (LBA)
/dev/hda5 66 319 2040223+ 7 HPFS/NTFS
/dev/hda6 320 323 32098+ 4 FAT16 <32M
/dev/hda7 324 577 2040223+ 7 HPFS/NTFS
/dev/hda8 578 1226 5213061 7 HPFS/NTFS
I made the FAT16 <32M to a Linux 83 type partition as /boot.
(i.e. I entered the graphical installation with expert mode so that I
could choose fdisk instead of the atomatic disk druid - later I got
into the portion of the setup where to define the mount points though
and I don't know if that was dangerous finally).
Anyway after adding Linux partitions and installing RH 6.1 I ended with
Win2000 rendered unbootable. At the lilo prompt I booted dos /dev/hda1
Something like ntldr.sys could not be found although booting through msdos.sys
up to the point where the secondary boot into the OS should be performed.
The partition table now looks like:
Festplatte /dev/hda: 255 Köpfe, 63 Sektoren, 2501 Zylinder
Einheiten: Zylinder mit 16065 * 512 Bytes
Gerät boot. Anfang Ende Blöcke Id Dateisystemtyp

/dev/hda2 66 1226 9325732+ f Win95 Erw. (LBA)
/dev/hda3 1227 1292 530145 82 Linux Swap
/dev/hda4 1293 2501 9711292+ 83 Linux

/dev/hda7 324 577 2040223+ 7 HPFS/NTFS
/dev/hda8 578 1226 5213061 7 HPFS/NTFS
Help appreciated, especially how I can recover booting into Win2k.
Could it be that naming order of partitions got garbled now under Win2K
and I just have to choose a different partition in msdos.sys?

It will, if you applied the e2compr patches to ext2 support in the

The shell expands wildcards before passing them on to 'cp' via
the argument vector... and the meaning of '*' is relative to
that directory, NOT to previous arguments such as modules.conf.
'cp: copying multiple files, but...' means that the 'cp'
command line, post-expansion, must have looked like:
cp modules.conf blah.bak [something.bak [...]] syscntl.conf.bak
\ /
\____________________.____________________/
|
|
*.bak -- namely every existing .bak file
in that directory (/etc).
And 'cp a b ... y z' is interpreted as "copy files a through y
to DIRECTORY z". syscntl.conf.bak was not a directory, hence
the error.
There must have been at least one other .bak file in addition to
syscntl.conf.bak, because if there had not been, the command
would have been
cp modules.conf syscntl.conf.bak
which is a perfectly legal, albeit unintended, command -- as
long as syscntl.conf.bak is writeable (e.g. not immutable,
and writeable filesystem) and there's space.
To simply copy ONE file and add an extension, you might be
able to use a shell alias -- although a brief glance at the
'bash' manpage suggests that you can't use arguments in
bash aliases. A short shell or Perl script would suffice
for multiple files, methinks.

TWAIN doesn't make the driver go away, it just puts a layer on top of it.
So, if I understand it right (I haven't used windows in 5 years or so),
the answer to that is probably no.

No. Or at least, it's not listed as supported. However, the C200 C30 and C20
are, and maybe the driver will work with the C500 (stranger things happen ;-)
