I wouldn't trust that disk anymore. I had similar problems with a Quantum

Try to put the output of the find command into an env var and then
check the value if it. If it is empty, then no action necessary. Otherwise,
yes.

I don't believe partition magic lets you resize ext2 partitions, you can
only create them, you can resize ms-dos partitions, but that is all.

Subject: My rc.firewall
Date: Wed, 01 Mar 2000 20:03:24 -0500
I found one or two good examples of rc.firewall scripts, but nothing really
comprehensive. So, I sat down and wrote one (1200+ lines so far). I figure
others might also benefit from my efforts, so I've put my rc.firewall script
on my web site <http://www.jsmoriss.dyndns.org/linux/rc.firewall>. It's
configured by a few variables, and there are some command line arguments. If
you get a chance to try it, let me know what you think.
Here's the "rc.firewall --help" output:

Begin at the beginning:
What is a link?
A link it's not the file itself, but only a reference to this
file. The original file is stored in another place (directory).
But you need this file - which always has to be the same file
as the original - in another place. That's why you create a link
to it.
What is a softlink?
Do the following:
% touch file (generates a file)
% ls -l file (lists the file)
-rw-r--r-- 1 mio user 0 Mar 2 file
% ln -s file slink (generates a softlink to this file)
% ls -l slink (lists your slink)
lrwxr-xr-x 1 mio user 4 Mar 2 slink -> file
^^^^^^^^^^^^^
The link is only a reference to your file. Nevertheless you can
put this link elsewhere in your filesystem and can do the
same what you can do to the original file. But it's still a
softlink. When you remove the original file, the link references
nothing, it's a dangling link then.
What is a hardlink?
Do the following: (the file 'file' is already present - see above)
% ln file hlink (generates a hardlink to your file)
% ls -l hlink
-rw-r--r-- 2 mio user 0 Mar 2 hlink
^^^
Here is no obvious reference to our file anymore. But in this
long listing the 'link count' increases, indicating that file
(and link) has to be linked twice.
A little bit deeper?
Ok, now the truth: Every file is a link. The filesystem has a
great table, where all the files it contains are listed. This
is called the inode table. Here all the references to the
physical data called 'file' are stored. When you read a file,
the read()-func looks up in this inode table where to look for
the data you requested.
You can look up the inode entry for your files.
% ls -i file
29462436 file
^^^^^^^^ the inode is like an address for the file.
The softlink has an own inode pointing to data, which points
itself to the linked file.
% ls -i slink
29462437 slink
Why so complicated? The hardlink simply has the same inode like
the file.
% ls -i hlink
29462436 hlink
And when should should I use softlinks and when hardlinks then?
The advantage of softlinks are:
- You can use them across different filesystems, because they're
not using the same inode table.
- You can track them better, because it is listed, where the
original file is.
The advantage of hardlinks:
- You don't loose a single byte on the filesystem, only in the
inode table (not a real advantage - who cares of single bytes
nowadays?)
- You can remove your original file here without effect for the
link: The data is still on the filesystem and appears via the
directory of the link in the usual manner. The data on the
disk is not touched, only the link count has been decreased.
(But this is not a brandnew backup-technique: Remember, the
hardlink has to be on the same filesystem, i.e. on the same
disk)

Solaris already has a GUI; in fact, that's basically what Solaris is:
SunOS + XSun + CDE (in Solaris 2.6+) + some other misc stuff.
CDE (IMO) isn't the most usable GUI ever, but you can work around it,
more or less.

You're saying you can print by invoking /usr/bin/lpr % s? If you are,
then there must be something wrong with my computer. I've tried every

I was unable to login as any user other than root today. When I entered

back to the login prompt. I didn't get nat message for an incorrect
user name or password, and when I get the user password and account
expiration dates, everything seemed OK. I deleted the users and
recreated the accounts, but this meant that I also lost all of the

My printer was behaving strangely today. When I tried to print a job, I

I don't know about RH6.1, but you can certainly mount a NTFS filesystem
read/write under SuSE6.1. I would suggest mounting read only, however
because depending on the size of the partition, and the size of the files
you copy over, you can end up corrupting the NTFS when mounted read/write.

Looks like you're trying to compile C++ with gcc.
It can be done; however, you'd have to add explicit options to link in
the relevant libraries.
Use g++ instead; g++ is a front-end to gcc that set the appropriate
linking options for you.
