I imagine it is because some companies are unwilling to give out their
source code that may well include full pathnames, and cannot be
bothered to support more than one distribution, so they pick the one
that they perceive to have the largest number of users that are likely
to want to use their product.
Alternatively, perhaps not all distributions follow the Filesystem
Hierarchy Standard perfectly, and they cannot bother to deal with all
the differences.

I know in some cases, though, the differences in the libraries cause
the problem. When trying to run IBM DB2 UDB V6.1, it would work on the
glibc-2.1.1 version, but would put several of the servers into an
infinite loop with the glibc-2.1.3 version so Linux would not even
boot up (because DB2 is started in /etc/rc.d/init.d). IBM claimed that
this was due to a bug in Red Hat's version of glibc-2.1.3 and IBM put
out a service pack that could be installed to overcome this. The
service pack is a download of over 100 megabytes and it sure took a
long time to download over my 56.6K dial-up connection. Even then,
there were a lot of difficulties, since the service pack could not be
installed until the older version of DB2 was installed, and it could
not be installed because of the bug, so you had to do a lot of
monkey-motion to partly install the old version of DB2 and then
install the fix-pack.
I imagine IBM would not have wished to do that with more than one
distribution.

I never tried Oracle, but I used to work for a large company that made
computers, and large software systems (UNIX OS for various machines, C
compilation system (compilers, libraries, run-time packages), ditto
for C++, etc.) and it was really tough, even though we presumably had
THE authoritative authors of those things working for us, just getting
the stuff to work for the machines we built ourselves and the others
we used in house, and for our own distributions. The problems with all
the different versions of the UNIX OS (there were 12 of our own that
we had to support at one time) were probably the biggest problem
(other than our marketing ineptitude) in making the UNIX OS a viable
commercial product. Several times we tried to reconcile all the
different versions of the UNIX OS into just one or two, and we never
really succeeded. We tried to do that again with the Berkeley, Sun,
and our own versions another time, and that only partly worked. These
kinds of things are really tough, much tougher than technical issues.

I tried debian last year on an old IPC. It installed ok from the web
(well, after we tried at least 3-4 different floppies for each image)
but we never got the keyboard nor mouse to work under X and also
simple stuff like man would segfault. Quickly went back to Solaris
2.6.
One other thing to note. Someone else mentioned in this thread that linux
software is also available for Sparc. That's only true as long as it's
open source. If it's not - say you want to use realplayer or whatever - then
you are out of luck although it seems possible to get the solaris binaries
to work with extra libs and lots of effort.

Davide,
Thanks for the reply. I have tried the ctrl/alt/+ and it does work,
however, it makes 800x600 huge, so much so that I have to scroll around the
edges of the screen to see the rest of the desktop. I have looked for the
XF86Config-HOWTO on linuxdocs.org but it is not there, where else might I
find it so that I can have a bit play with xf86config tool.

hummm... I found it in the LDP site, if it's no longer there, I think
they have "incorporated" it in some other how-to (the XFree86-HOWTO
for instance...).
Try also the http://www.europe.redhat.com/documentation/HOWTO/XFree86-HOWTO
(this is a bit specifical for RedHat, but the 'basis' are there...).

I have a Sparcstation 1,2 and 20 and run RedHat 6.2 for Sparc on all of them.
They run just fine, and compared to Solaris 7 they run *MUCH* faster. Be
forwarned that a Sparcstation 2 is not the fastest machine on earth to begin
with but is quite useable for a server (intranet or otherwise). I would
recommend putting as much memory in the 2 as you can get a hold of though. If
your sparc isn't as snappy under RedHat 6.2 as you'd like, the other
alternative would be to run NetBSD on it which is quite a bit lighter.

Subject: Ipchains vs Checkpoint vs CyberWall
Hello all,
We are planning to set up a firewall for our network of about 50+ Win 9x
stations, a couple NT servers and a dozens of RH Linux servers (database,
email. web, ftp, etc.)
Since the firewall will be on a server by itself, so it can be a Windows or a
Linux. How does IPCHAINS stack up against its counterparts in the Windows
world like Checkpoint, CyberWall and others? What features found in
commercial packages that IPCHAINS lacks?
Also, is hardware firewall better that a software firewall?
Thanks in advance for sharing your info and suggestions. If anyone knows of
any such doc online, pls point me there. Any comment is appreciated.

There's no overlap.
You're lacking the basics.
hda2 is an extended partition (a container partition)
hda5 and hda6 ar logical partitions that are located inside the extended
partition. Without extended partitions you would only be able to have
four partitions at the maximum.This due to a lack of space in the MBR.
So be glad they exist, you never noticed them in DOS eg. , because
DOS FDISK only names the primary and logical partitions. the extended
is left unnamed.

What I meant here was not that they wont fail, -a old version would-,

Subject: How to release a DHCP lease from a Linux client
Date: Mon, 12 Mar 2001 13:56:09 -0000
Hi everyone,
I am having the following interesting problem:
My Linux RedHat 7.0 client (kernel v2.2.16-22) is using DHCP to get an IP
address for its eth0 interface.
When I tried to telnet into it from a Win2k client, it would not accept my
credentials (login incorrect). Sometimes the connection would just be
dropped as well before I had time to enter my credentials.
But then I noticed that the logon banner was different than what was
specified in my /etc/issue.net.
I then looked at the arp cache on my Win2k client, and the mac address for
the system did not match!
I edited manually the entry in the arp cache and then everything started
working properly, until the cache expires and then sometimes that other MAC
address re-appears, and my connection is dropped.
So I figure that some other Linux system is using the same IP address only
it must have been assigned statically because otherwise the DHCP server
would not lease me that address...
My question therefore is:
How do I tell my Linux server to try and obtain another lease (so that it
gets another IP address).
Now in NT (I'm an NT guy), ipconfig /release and ipconfig /renew will get a
brand new lease, but how do I do this in Linux?
Any help would be appreciated.
Cheers,
Stephane B.
