if your system is anything like mine (debian so it might not be) then in one
of your shell startup files (eg ~/.bashrc) there will be an alias setting ls
to colourise, something like the following
alias ls='ls --color=auto '
comment it out. The effects will only take place when you next log in, but
you can type
unalias ls
to remove the alias from a running shell

That line right there is the important one.
Unfortunately, I'm not certain whether "peer" in this case is
you or your ISP. Is your connection governed by DHCP? Are
you trying to use 217.52.7.110 as your IP address? Or is your
ISP using that address maybe and your system isn't accepting
that for some reason? One of those two things is probably
your problem.

We had a 2.2.X kernel that would kernel panic everynight during a backup
because we were mounted to it on an NFS mount.

You can start the application in the profile scripts. IIRC, Pick required some
environment variables to be set. Set these, launch the pick executable, and make
sure to put an exit as the last line of the profile. This prevents them from
returning to a shell when they exit the application.
A better way might be to use sudo and have sudo run the executable.

Try going to docs.sun.com and searching for IPC. The 'System

place to start.

A new initrd is not always necessary. The main reason to use it is to prevent a
"chicken and egg" scenario. For example, you need a particular module to be able
to use a SCSI device to be able to see your drives. You can't see your drives
unless you load that scsi module.

Besides the above, there's also a small performance gain from building modules
directly into the kernel. For high usage networks the difference could be
substantial.
>From your posts it sounds like you are trying to load modules that are
unneccessary. Try using the --ifneeded option (look at "man mkinitrd") or
-omit-scsi-modules parameter if you don't want to load the AIC modules.

There are multiple methods of doing IPC, depending on what your requirements
are. Basic "UNIX" facilities include the use of pipes (half duplex) and
named
pipes (full duplex, aka FIFOs). There is also UNIX domain sockets for
full duplex communication between processes.
Traditional System V IPC consists of;
- Shared memory
- Message Queues
- Semaphores
POSIX came along and added;
- Shared Memory
- Message Queues
- Semaphores
[see a pattern? :^)]
Basically, you have 2 different and distinct sets of APIs for doing shared
memory,
messaging and/or semaphores. The POSIX and SysV interfaces are very
different,
and while they provide similar functionality, there are some important usage
differences. They are also implented very differently; Sys V IPC is
implemented
in the kernel, POSIX IPC is implemented using mmap'd files.
Solaris also provides an extremely poorly documented facility called Doors.
To learn how and when to use these facilities, please read;
UNIX Network Programming, Interprocess Communications, Volume 2,
Second Edition. by W. Richard Stevens. ISBN 0-13-081081-9.
To learn a bit about how they are implemented in Solaris, please read;
Solaris Internals. by Jim Mauro and Richard McDougall.

Subject: BIND 8.2.2-P5 DoS - Update to 9.1.2 or 8.2.3 ?
Date: Mon, 07 May 2001 15:22:31 GMT
Hi,
We're running BIND 8.2.2-P5 on a RedHat 6.2 PC and since last friday,
we are getting regular denial-of-service attacks. I've seen on
<http://www.isc.org/products/BIND/bind-security.html> that updating
could maybe help us.
Now, the question is, should I update to BIND 9.1.2 or BIND 8.2.3 ? I
know that 9.1.2 has some major changes, so we would need to review our
config files. Is it worth the effort ? Maybe 8.2.3 would be just OK
to stop the DoS attacks ?
Thanks for your advices people !

Thanks, Eric, an excellent suggestion. It works fine:
sh-2.04$ ls -l a_testfile
-rw-r--r-- 1 epstein users 2203058176 May 7 09:38 a_testfile
sh-2.04$
Furthermore, the following works as well:
gzip -d nt.Z >nt
sh-2.04$ ls -l nt*
-rw-r--r-- 1 epstein users 3293252235 May 3 22:46 nt
So now I have a workaround for my problem, but would still like to issue a
bug report and/or build and test a fix on my own system. Any pointers for
doing this? I have all the RedHat source code on CDs, but it's in a bunch
of RPM's and I don't know which RPM corresponds to zcat's source.

I'm trying to make a bootable CD using the mkisofs' -hard-disk-boot

I've got as far as getting it to make an ISO9660 image by doing first
dd if=/dev/hdc of=hd.img bs=1k
(where hdc is the hard disk image I want to put on CD) followed by
mkisofs -b hd.img -hard-disk-boot -c boot.catalog -o bootcd.iso .
But when I try to boot from a CD with this image, after printing LILO all
my 'putter does is print a stream of numbers scrolling down the terminal.
Does anyone out there know the trick to making bootable hard-disk images
