I was reading the BTS column in the April issue, and noticed that for the ``Wrong Date'' question from Bilal Iqbal, you edited my answer, changing the meaning. In fact, you reversed the arguments to the ln command. The link should be
ln -sf /usr/share/zoneinfo/US/Pacific \ /etc/localtimeand the -f option is most likely needed, since most systems already have a link there. Also, I said ``a link like this'', not ``create this link'', since the reader specified his timezone was GMT+5, so telling him to create a link setting his timezone to GMT-8 isn't exactly what he would want to do.
I am using a Zip drive with Red Hat 5.2 and cannot
use my printer
because the Zip drive is a parallel port version. The printer manager
does not recognize the printer is connected. I was able
to use the printer before the Zip drive was installed. Is it
possible to use both the zip and the printer? I know I cannot use
it while my zip is mounted, but when I unmount the drive, would it be
possible?

Rebuild the kernel, defining lp and zip support as modules. When
you wish to use the printer, unload the zip module (if loaded) and
load the lp module, so you can use the printer. When you wish
to use the zip drive, unload the lp module (if loaded) and load
the zip module. That's it.

According to the Zip Drive mini HOWTO, question 7.1
(http://metalab.unc.edu/LDP/HOWTO/mini/ZIP-Drive-7.html#ss7.1),
it should be possible.
You will need a newer kernel (2.2.x) or you'll need to upgrade the
ppa driver in your current kernel source and recompile it.
Since RH 5.2 isn't fully compatible with the 2.2.x kernels, you
may be better off recompiling your current kernel, and you can find
the ppa driver on David Campbell's page:

I just got Linux about a month ago (Red Hat 5.2) and have
been experimenting with it.
Last night I accidentally ran mkfs.msdos on my Windows 98 FAT32
partition (/dev/hda1) thinking it was a command to mount an MS-DOS
partition under Linux, but of course, it nuked my drive, created
an MS-DOS partition over it, and I lost everything on my drive!
I am writing to you in hopes that you know of a way that I can
salvage the information still on my drive. The mkfs.msdos
command erases only the FAT sector when it creates a new file
system, right? So, shouldn't all the information still be there?
Thank you in advance for any assistance.

That's a rough accident. The short answer is there's little you can do. Yes, the information is still there, but the FAT tables tell the system where to look for different pieces of a file, and if your file system is fragmented, it could be very difficult to recover anything.
However, it would be worth trying a few recovery tools, such as Norton's
Disk Doctor if only to salvage some of your data before you reinstall
Windows. You may be able to save something from your disk if you touch

Normally, I am an IRIX user. Recently, I bought a dual-Pentium
machine and installed Linux SuSE 5.3. on it. I can't figure
out if my second processor is recognized; there seems to
be no command like hinv in IRIX. Any suggestions?
Is there any document comparing IRIX and
Linux commands?

First, you have to make sure your kernel is compiled with SMP support; this is not the default for most distributions. Then check your /proc/cpuinfo file which contains the information for all CPUs found during boot time.
In order to take full advantage of your dual processor
machine, I'd suggest you use the 2.2.4 kernel version,
which is the latest at this time.

I installed xeyes in the KDE menu and while trying to remove it,
it multiplied. Is there any way to close it? It has no resize window
and every method of stopping or interrupting doesn't prevent it
from returning on bootup.
I have searched the man pages for a key combination to kill them
to no avail.
--
Edward Spadacene, espada@mbox.kyoto-inet.or.jp
You can close xeyes by clicking the right mouse button on it and
choosing ``Close'' from the pop-up menu that appears. Next time you start KDE, xeyes will not be run.

I am trying to set up my firewall so that my users can play on-line games. In particular, I need to set up the following ports:
Unless you set up additional firewalling rules, there is no way
to allow the outbound packet on port 47624.
Outbound UDP and TCP connections in the 2300-2400 range will work
fine, and the masquerading machine will open a reverse connection
to gateway back inbound packets if they come back on the same port.
If they don't, you may have some luck with the ipautofw packet forwarder
which you can get at
ftp://ftp.funet.fi/pub/Linux/PEOPLE/Linus/net-source/firewall/ipautofw.tar.gz.
You may also want to look at the ipmasq-HOWTO and the list of applications
that can be made to work through IP masquerading,

Is there a default directory for downloads? I used the included
Netscape Communicator v4.07 to download the Corel WordPerfect
Suite 8 for Linux (a 25MB download that took a couple hours)
and the Quake 2 for Linux demo. When I went looking for the files
to install them, I couldn't find them anywhere. The system
did not ask for a specific location to place them, so I assumed
there was a default location. Am I wrong?
--
Robert Gray, noeman5@hotmail.com
By default, Netscape tries to save the file in the user's home directory or the last place (path) where you saved a file. To locate the files, use the command find:
find / -name "corel*.tgz" -print--
I had a hard disk crash and cannot mount root directory
/dev/hda3. Is there any way to perform a partial recovery
of the data on the drive or split the root partition
(skipping the bad sectors) from a boot floppy? I only
need the most recent data in the mail directory that was
not backed up.

Boot using a rescue disk and try to repair the
partition with the command fsck.ext2 /dev/hda3.
After that completes, try to mount the partition yourself and
dig out the needed files.

I have a Linux system that the hard drive died on. I have a
tape backup of the entire system. I did a minimum install of
Red Hat to get the new drive running, created the
partitions / and /big and told taper to overwrite all files.
It ran and restored its files but had over 1200 errors. I viewed
the log, which contained statements about checksums not really
errors.
I was hoping to be all right, but when I rebooted, the system
just printed LI and stopped. Any help you could offer
would be greatly welcomed.
--
Jabe Pitts, Jabe.Pitts@cwix.com
Your system is probably fine--this is a boot loader issue. Boot
loaders need to know where the kernel is located, and by restoring
your tape, you overwrote the kernel, which moved it to a new position
on the drive. Use a boot floppy to boot your system and run lilo.
This will reinstall the boot loader. (Note that you may need to
use

I got a message like the one below when I was trying to install guile. I usually can figure out what needs to be installed when I get these failed dependency messages, but this time I'm flummoxed. I have both glibc 2.0.7 and 2.1.x installed. Is this just a peculiarity of the RPM? I've gotten this message with a bunch of RPMs I've tried to install recently, not just this one.
[root@localhost new]# rpm -Uvh guile-1.3-4.i386.rpm failed dependencies: libdl.so.2(GLIBC_2.1) is needed by guile-1.3-4 libdl.so.2(GLIBC_2.0) is needed by guile-1.3-4 libm.so.6(GLIBC_2.1) is needed by guile-1.3-4 ...--
Well, it turns out that glibc 2.1 isn't exactly binary compatible with glibc 2.0. It looks like that's the problem you're having. Grab the .src.rpm file instead, and do
rpm --rebuild guile-1.3-4.src.rpm.The resulting .i386.rpm should work and will be in the /usr/src/redhat/RPMS/i386/ directory.
I am a Linux newbie. Whenever I accidentally shut down my system
without halting, I get a message telling me to run disk utilities, and
remount hdd. I was wondering, what disk utilities? How do I
run them? How do I remount disks?

The utility to run is fsck which checks and repairs a Linux file system (whether it is ext, ext2, etc.). In order to mount one yourself, type:
mount -t filesystem-type device mount-pointFor example:
mount -t ext2 /dev/hda3 /archiveJust make sure you already have the mount point created (use mkdir), and you are using the correct file system type (ext, ext2, vfat, etc.).
