Hi all,
I heard that there is a big security hole in RH 6.2. Has
RH fixed it with their current release of 6.2 or does it
require that the administrators patch it up themselves?
How about RH 6.1 (which is the version I am currently running)?
I didn't see any security advisory on the RH web page for 6.1
but did see one in 6.2.
Anyone like to add to this?

I found Duane Hellum's 'Red Hat Linux Installation & Configuration
Handbook' useful. When configuring things it's easier to refer to than
HOWTO's. Lots of dross, though, and it covers 6.0 rather than 6.2. More
of a beginner sysadmin book.
If you're not too familiar with Unix/Linux and expect to do things with
the shell, Kernighan & Pike's 'The Unix Programming Environment' is a
must have. It's a classic in the sense that it's been around a LONG time
(ca 15 years), but it's about the best high level primer for Unix(like)
systems I've read.

What you are suggesting is nothing new, it has been around since the first
timeshare systems. My interpretation of your article is that you will be
reintroducing the old timeshare system that have overall been rejected
because of serious issues of security, privacy, and reliability. Not to
mention the performance bottle neck at centeral unit.
It seems that your have read avout Microsoft.NET and you suggesting a form a
Linux.NET. Microsoft.NET has too many issues for it to work, without one
hell of an expensive advertising campain directed to form clueless userbase
that are unwilling or unable to realize the problems with Microsoft.NET are
indemic with it core to the point that it cannot be fixed with todays
network bandwidths.
How are your planning to handle the bandwidth problem? How are you planning
to get the OS and libraries and other software on a host that is needed to
handle XML without having to install it? Who is going to run the servers?
Were is that data going to be stored? Who will guarentee that one day's
data files will be readable by the programs available the next day? Who is
going to defray the cost of running the servers? etc.

Subject: Power failure - how do I fix...
Date: Thu, 24 Aug 2000 05:48:26 GMT
I have a Linux box running (at least it WAS running) RedHat 6.x. I divided
the hard drive into 4 partitions, and set them up as /, swap, /usr, and
/var. A power failure messed up the partition containing /var, and I had to
run fsck. After taking the default answers to such questions as "Clear this
inode?" and "Delete duplicated data blocks", the /var filesystem contains
nothing.
So, how do I figure out what needs to be there? I remember that I need a
/var/log directory, a /var/spool directory and a few others. What I'm
looking for is an authoritative list (if such exists) of what should be
there, or what likely ought to be there.
I can't find such a list. Anybody got any ideas as to exactly where to RTFM?

Windows 95 is less reliable than windows NT in part because the former
is expected to run a lot more old software, i.e., DOS and 16-bit Windows
software. The original releases of MS-DOS didn't provide soup-to-nuts
services like the more recent versions of Windows, so way back software
developers got in the habit of bypassing the OS. If their software got a
large enough market share, future versions of MS-DOS (now Windows)
needed to support it. In other words, Microsoft OS's are products of
accretion. This was a market imperitive.
Then there's DLL hell. Other companies bundle DLLs that they install
with their executables and other files, and sometimes (often?) they're
not the most recent versions, so they can screw up other applications
and the OS itself.
>Also, what improvements to Linux would you make to make it as

Well, IMO, multiple user OS's will never be too popular with the general
public. I'm the only adult in my extended family (friends are too skewed
a sample - only family is random) who doesn't mind having multiple IDs
on one PC. Home PCs need to be simple to set up, easy to start, easy to
launch CD/R-based applications (e.g., games), and easy to connect,
configure and use peripherals (printers, modems, etc.). Linux isn't
close yet. Mac OS X and BeOS are good examples of unix-influenced single
user OS's.
The majority of the general computer user population is currently very
willing to sacrifice security and some reliability for convenience.
Microsoft caters to that.

I'm using the G400 with 3.3.6 and Mesa 3.2 too. No problems so far with
the Mesa-demos and other OpenGL stuff except for Moonlight and Unreal
Turnament (seems SDL is not using libGL.so). Did you install only the
libGL.so from glx or did you an install of Mesa too ? Then some programs
could use the Mesa-GL lib and therefore use software mode. Try a 'find
/usr -name libGL.so' and remove the ones not belonging to glx.

Hi all,
I had a go at this this morning.
When I try that mount command, I get an error that / is busy.
If I try the e2fsck command it warns me that I could corrupt data running it on
currently mounted partitions, so I figured I better not :)
I tried booting from a (pair of) disks I made when I installed linux (slackware
7.0) and they can't read the hard drive partition to get the e2fsck program, so
I tried copying it to a floppy, but I can't mount /dev/fd0 - there is a line in
fstab about /dev/fd2 - but that comes up as being special (something, can't
remember ATM), and it won't fit on the boot (root) floppy.
Any suggestions?
Regards
Quentin.

Also, remember that the file name passed to the open system call is
terminated by \0. This in itself makes it impossible to have a \0
character in the middle of a file path name; or if you could you would
not be able to open it, and that is not much fun.

If you're not careful people will take you for a troll. There is never
a big security hole in a distribution, but there might be security
holes in programs included with the distribution, and there always are
and there always will be.
For security problems in Red Hat 6.2, see
<URL:http://www.redhat.com/support/errata/rh62-errata-security.html>
for updates on security holes in programs distributed with the
distribution.
You, as an administrator, is responsible for updating and maintaining
your own machines.
Stop trolling.

/dev/ttyd1 could be used on IRIX, but you would not usually want to.
/dev/ttyd1 is only used when you want software flow control -- not
recommended for serious byte transfer duties above 9600.

Drivers are named thusly. The old Open() behaviour would try to Open a
driver named that name and if you were horribly unlucky to have a file
named after a ROM-based driver like, oh, say, .Sony, etc.... you'd
definitely get interesting results.
:)
Hence why the recommendation to use OpenDF() etc. That call will never
use the DriverOpen() code.

Whereas I hope to not catch too much flack for this, my preferred linux

to, I cannot get it to scale past the default 80 rows x 25 columns.
When I compiled joe, I got termcap and terminfo conf files, but they are
difficult (read: impossible for me) to understand. I know that joe can
scale past the default because I have done so on other machines. Also,
I've looked at pico and it scales fine on this machine. There are
command line options -rows and -columns that each take a parameter, but
these don't seem to help. If anyone has had this problem in the past or
knows what a terminfo file is and how to edit/understand it, I'd GREATLY
appreciate it if you could enlighten me. Thanks a lot.

That's true for the implementations of video in X which I've seen (comparing
the playing of VCDs using xanim with using the Windows Media Player). Is it
necessarily true of the linux/X platform, or is it just the applications
I've seen ?
