First of all, this is what your system does everytime it boots. It
first mounts your root filesystem read-only, performs some checks
and then remounts it rw.
There is an option to mount that is used for unmounting and mounting
in one step (remount). I just say: RTFM/man mount.

If you would successfully umount your root filesystem, where would you

The second solution can help you in the future whenever there is a problem
booting: Download the tomsrtbt 'Linux on one floppy' from www.toms.net.
Boot this floppy and then mount the partition in question manually (i.e.
without using /etc/fstab, again just read the full manpage to mount) vi
fstab and there you are.
Good luck

How did you make the .iso file in the first place? And can you check
the .iso using the loopback, like so?
mount -t iso9660 file.iso /mnt/other -o loop,ro
should mount the .iso on /mnt/other --if it coughs up error messages
unrelated to the lack of loopback support in your kernel (Put it in!) or
the nonexistence of /mnt/other (mkdir it), then the .iso file is more
than likely corrupt. To make an .iso file out of a data CD, just do:
dd if=/dev/cdrom of=file.iso bs=2k
xcdroast is a frontend to cdrecord and mkisofs--nothing more, nothing
less. What works in xcdroast *must* work in cdrecord. Does cdrecord
cough up any errors while burning?

Can you use efax for a faxserver instead of hylafax, too?
I have the same problem (class 1 modem).
I wanted to run a daemon for fax jobs on my linux server and all windows clients
should fax over the network.
Can I do this?

I think its not exectly that you are searching for:
Try nettrafd. Its a client/server program. The server runs on linux and sends
the amount of nettraffic of e.g. ppp0, eth0 or what you want to the clients,
which run on windoze and will show you a diagramm (? I don't know the word).
I think I found it on freshmeat.
Here is the homepage: http://nettraf.webjump.com/
There is also a screenshot of the client. Have a look at it.

In that case, I'd think you'd use Slackware, since the only advantage
of RH or RH-derivatives is "package management", which you have abandoned.
I'm a Slackware hold-out slowly migrating to rpm-based systems simply
because package management does make life a little easier. (Admittedly,
Slackware does have a package tool, which is helpful, but not thorough.)

How about a simple shell script?
Hmmm... something like:

for v in $*; do
mp3towav $v $v.wav
adj=`sox $v.wav stat -v 2>&1`
sox $v.wav -v ${adj} -t wav - | wavtomp3 - $v.tmp
mv $v.tmp $v
done
Of course, you'd replace mp3towav and wavtomp3 with your favorite
applications. Personally I don't have anything to go from mp3towav, so
can't offer any suggestions. wavtomp3, I'd probably use something like
lame -v -V0 -b 128 -t - $v.tmp
Nice thing about this is, you can't play around with different utilities
for decoding and encoding until you get something that works best for you.

You *can* connect to a public ip address through a MASQ-ing proxy, using VNC
.
If your linux is using a 2.2x kernel, use ipchains,
I forget the complete syntax but you have to say,
when source is your internal ip and port is 5900 -j MASQ
-s <your ip> 5900:5900 -j MASQ
You have the forward chain DENY by default, right ?
If your proxy is not MASQ-ing, then I am clueless.
Hope this is of some help.

This was your comment to my quote from the fdisk manual page:
"fdisk is a buggy program that does fuzzy things - usually it happens
to produce reasonable results. Its single advantage is that it has
some support for BSD disk labels and other non-DOS partition tables.
Avoid it if you can."

NO!!! ( capitals intensionally used as in a blood curdling scream)
cp has an option to preserve the user/group id's. It's in the man page .
man cp at the xterm or the console
I only know of one way to do this :
as root, copy out the entire /usr tree ( with the option to preserve group
and owner data ) , tar and gzip it, and put it somewhere safe. Preferably
another hdd on another computer .You could even use samba and dump the file
on a w2k drive.
Then unmount the /usr partition, proced to delete it with fdisk. Make a new
one, and then use mke2fs .
mke2fs /dev/hda7
there may be options to mke2fs that I can't remember now ( did all this
about a year ago ), so consult the man pages on mke2fs before jumping in :)
After it has put in the ext2 file sytem, mount the partition as /usr, and
untar your backup into it .
Don't forget to go into /etc/fstab and change the entry for /usr to point to
the new partition number.

RH 6.0 :
I started with 64 MB . Linux saw it all.
In January, I put in 64MB more.
Linux reported 128MB physical.
Moved the hdd to a MB with amd751/756 chipset with a t-bird , and 128MB of
memory.
It's still *not* giving me problems.
If linux needs the mem= line, then why is it seeing all of the memory in my

Is there something that happened "automagically" in the background that I

It's all about the BIOS. There are several different ways for the BIOS
to report how much memory is available at boot time. The old way that
dates back to the early 80s is supposed to return a maximum of 64M, and
every BIOS supports that method of memory detection. (INT 0x15, 0x88).
A similar method (INT 0x15, 0xe801) can return a max of 4G (I think...)
but not every BIOS implements this. The final method, (INT 0x15,
0xe820) is apparently used by some BIOSes, but the code for supporting
it is rather hairy since the BIOS can return a memory map with a bunch
of holes in it. If your BIOS doesn't support e801 and you want to use
the stable kernel series, you sort of have to pass "mem=XX" to the
kernel if you wish to use more than 64M, since the 2.2 series doesn't
seem to have support for the e820 method.
Most info stolen from /usr/src/linux-2.4.0-test5/arch/i386/boot/setup.S
, naturally.
(Any PC-BIOS gurus, feel free to correct whatever glaring errors I
made.)

I'm afraid that my copy of "man fdisk" does not contain this text. It
does contain this though:
BUGS
There are several *fdisk programs around. Each has its
problems and strengths. Try them in the order cfdisk,
fdisk, sfdisk.
None of the manpages for these versions of fdisk contains the text you
quoted. Perhaps you have a very old copy of fdisk? My manpage is
dated 11 June 1998.
If your theory of "cyclic partitions" were correct in general for large
disks, then we would be hearing the screams of pain from all quarters.
Instead, we hear only from people with old BIOS.

Subject: Booting linux from ZIP
Date: Mon, 07 Aug 2000 16:33:31 GMT
Hello,
I'm making a system with only one iomega-ZIP disk (ATAPI version
connected to /dev/hda) and memory (without hardisk or CD). While
installing, I connected a CD-Rom to boot and install Linux (Suse 5.3) in
a ZIP diskette.
I configured a partition (/dev/hda1 to full disk size) and installed
LILO. The BIOS can boot from device LS/ZIP.
When I reboot the computer, the ZIP drive blinks the LED (I suposse it
is trying to load boot sector) and then BIOS shows the message "INSERT
BOOT DISK".
I can't boot from ZIP drive, but I can load the kernel from CD-ROM and
then, set the root partition to /dev/hda1 that is ZIP diskette.
Is there any problem with LILO in ZIP drives?
Thanks.
