Date: Mon, 06 Sep 1999 12:31:10 GMT
I would like to protect the data on a removable hard disk against
unauthorised acces from persons who might get phisical access to it.
Is there a way to transparently encript the data writen and decript the
data read from the drive in question?
Thanks,
Camil

I'm using ipfwadm for firewalling (Redhat 5.0) and have my deny rules set
to log attempts. Right now those messages go to /var/log/messages. I
read the syslog.conf man page but can't figure out how to have these
messages sent to an alternate file. Can someone tell me what the syslog.conf
line should look like to redirect these messages?

I havent read the HOWTO but there is an easy way to undelete. I use
the Midnight Commander clone mc. it has an undelete function which
works just fine. You dont get to see the filenames so some guessing
is in order but who cares. As long as you havent overwritten the area
you should be able to revover the file.
good luck.

PS: I know that mc on RH6 can do it, I dont know about the earlier
versions though.

How about reading the documentation? It's there for a purpose! Please
check all files in "/usr/doc/windowmaker/" (especially the FAQ) and
try "man wmaker" on the shell prompt.
Good luck, P. *8^)

It sounds like many of your problems are to do with X. Gnome in
particular. At the risk of getting shot, I'll encourage you to try KDE.
(Sorry about the taskbar though).
Now, released to the public for the first time, under the terms of the
Gnu Public License is my patented tool for managing buggy X
applications:
#!/bin/sh
umount /mnt/floppy
while true
do
if mount /mnt/floppy
then
umount /mnt/floppy
killall X
fi
sleep 10
done
Run it as root. When your X server hangs up, just push in the floppy
disk and wait a few seconds.
No need to hit the power switch!

Subject: uudecode and e-mail attachments
Date: Mon, 06 Sep 1999 12:50:21 GMT
Hello,
I am having trouble opening e-mail attatchments sent to me in a
readable format. I use Red Hat Linux 6.0, and attachments in the
following file formats do not open legibly: .txt, .rtf, .doc, and word
perfect file formats. Presumably the situation is the same with other
file formats
Sometimes I can open the files, but mostly I cannot. Occasionally,
a file will open with the heading "base 64". Sometimes I can save and
uudecode such a file; sometimes I cannot. The behavior is consistent
irrespective of where the attached file originates. One common factor is
that the producers of the various file attachments all use MS Office 97.
The problem occurs when I use the following e-mail software:
StarOffice 5.1, Applixware 4.2.2, Netscape 4.5. To the best of my
knowledge, the systems from which I get my attachments are using
uuencode in sending e-mails.
Does anyone have a solution to recommend and suggestions of where
to look for documentation? The three programs I use don't appear to have
much in terms of documentation regarding this problem.
Thanks
Milkman

Subject: Linux+NT dsaster (help wanted)
Date: Mon, 06 Sep 1999 15:29:06 +0200
A colleague has an NT Dell Latitude CPt and according to NT's
disk manager this is how the partitions look like:
+-------------+---------------+---------------+------------+
| FAT | NTFS C: | NTFS D: | Free |
+-------------+---------------+---------------+------------+
Now since the install was done when you try to boot the laptop
you get a black screen with "Invalid partition table" and nothing
else. The only way to get the machine to boot is with the NT
boot disk which then boots NT. We copied the boot.ini etc
from the boot disk into C: but still the same results (it says
to boot from partition 2).
I think that during installation the MBR got overwritten by
LILO and somehow it cannot find itself. We have been thinking
about doing "fdisk /mbr" from NT but are worried that perhaps
that will screw up the whole thing. Will that restore the
ability to boot NT from HD? or what? We can install Linux again
but NT install/reconfigure would be a nightmare, so is there
a way to first make this thing boot NT from HD? any plans on
how to proceed? any help would be greatly appreciated.

try a web search 'Linux Guide' 'Joshua Go'

I printed out recompiling the kernel. THere are other guides out there,
but after I did the first one it's not THAT daunting if I had to do it
once more. I only had to re-do it because I tried out a different distro,

Yes.

3 possible ways. First is to boot Linux off a floppy. That leaves the original
hard disk absolutely and completely untouched. Second is to install and run
LoadLin from your windows disk. Loadlin is a DOS application that will
load and boot linux. It will require you to copy a kernel to your windows
disk. Other than that it will not is any way shape or form interact with
that disk after booting. The last is to use LILO which will create a new
Master Boot Record on your primary disk. This is the most invasive option.
Considering your concern with the Windows disk and the abject slowness of
floppies, I think the LoadLin route is probably optimal for you.
> Would it be
>possible to run Windows, and then start a linux session in a Window?
Not normally. 98 and Linux are both operating systems and both expect to
have sole ownership of the machine when running. So when you run Loadlin
from Windows98, Windows will be shut down when Linux is booted.
ANother possibility is to take a look at VMWare, which is a Virtual Machine
that allows one to run a Guest Operating System on top of a Host operating
system. But from what I've read Win98 cannot be a Host Operating System. So
while you can run a Win98 session on top of Linux, the reverse is not true.
But taking a quick look at their website (http://www.vmware.com) apparently
Win2000 will be able to be a host OS. BTW VMWare does cost....

Choose what works for you. If you need an OS that supports peripherals
that require Windows drivers, that runs apps that require Windows and so
on, then do you really have to ask someone else?
If you are just looking for an excuse to learn something about your
computer and Unix, then go ahead and play with Linux.

I am trying to set up remote printing with lpd (not samba).
When I try to print, nothing happens and no mesasges are output
to /var/log/messages or syslog. But if I do lpq I get the message:
[printserver]: /usr/sbin/lpd: raw: your host does not have line printer
access
even though I have added the host to the print server's /etc/hosts.lpd,
and restarted lpd numerous times, and even reboooted the printer server.
Is there some trick to this?

Someone had indicated that the patch set would apply OK except

changes. But when I tried it, no go. Everything compiled but
something unpleasant happened during boot so I went back to the
2.2.11 kernel with the working patches.

This normally means that a major system error/problem has occurred and
the system cannot finished booting up. This can happen for example when
you have moved a partition like /var or /usr. As these contain system
files and info the kernel would give that message.
Have you moved/deleted/rearranged any partitions? Are all your disks
accessable?

A 36" monitor? are you sure? Any way here is what you do,
1) search the web for the Video HOWTO or X-Windows HOWTO for linux which should
tell you if your video card is supported. Better yet go to the
distribution's site and check there.
2) Go to Gateway's website and get as much info on your monitor as possible.
Pay special attention to the monitor specifications. Look for resolutions
and refresh rates possible on your monitor. Then when you install linux
tell it what your monitor can do and it will oblige. BEWARE if you give
linux the wrong info it COULD fry your monitor, so dont make too big
a mistake.
good luck
