We run all of our DNS on Linux which is very critical service (if it's
down so is everyone else). It's been rock solid since we put it in
place. As Steve mentions there is no one size fits all. It's funny the
comment about Linux drivers, as Linux supports way more hardware then
does HPUX :-) I don't know how it compares to Windows but I know I have
not found hardware that Linux will not run on yet although I am sure
such hardware exists (especially with the 2.6.x kernels). There should
always be a place for HPUX/AIX/etc but I think with grid computing and
Intel/AMD processors Linux will surly find a place in addition to all
small to medium servers.
Just my $.02

This is an interesting post and one worth responding to--even if it is
O.T....
I agree with you that Linux is not the "all-encompassing solution." No
O.S.
is (despite vendor's claims). Overall, I believe Linux is a great
platform
with a lot of potential. It still has a way to go before I would feel
comfortable using it on our key systems (where OS'es like HP-UX
shines), but
it is more than adequate for providing small- and medium-scale
services. We
have applications running on Redhat 7.3, 8.0 and 9.0 (If it works,
don't
break it...). Linux is also "slowly" beginning to making inroads as a
desktop platform (I am using Fedora Core 1 on a Pentium II-266 w/192 MB
RAM
as my primary "administrator" desktop with Windows NT as a "backup.". I
am
also using Mandrake 10 at home). Overall, Linux is proving to be a
very
stable and reliable platform and seems to be improving with each new
release.
There are areas were Linux needs improvement, especially in the area
of
hardware drivers. These problems also tend to vary with each
distribution
(i.e. Redhat, Mandrake, SUSE, etc.) and each release (e.g. Redhat 8.0,
9.0,
AS3.1, etc.) which also tends to complicate matters..And, while desktop
apps
are improving significantly, they still need to be "tweaked" a little
more
before they are ready for distribution to most end-users.
For the most part, once Linux has been installed and is running, it is
fine.
While I don't believe Linux will ever be like HP-UX, I will continue
to
recommend it for many projects based on my experiences with
it---especially
if Microsoft is one of the options :-) .
Have a great day,

Subject: [HPADM] OT: Thoughts on Linux, Future? or not?
I haven't posted in awhile so I hope "OT" is still the right symbol for
"Off
Topic"
I've been an HP-UX administrator for over 10 years (some Solaris and
SGI
too, but mostly HP-UX). Lately there has been a big push within our
company
to look at Linux, specifically RedHat (AS 3.0 and 2.1). It seems that
everyone wants to jump on the Linux bandwagon, but I'm not convinced
Linux
is the all-encompassing solution that so many seem to think it is.
The biggest motivation for moving to Linux is financial (from the
"higher
ups" that is). The hardware is cheaper and so is the OS. However,
it's
been my experience--so far at least--that what you save in hardware
and
software you quickly use up in Sys Admin time. I have spent so many
hours
trying to get a particular driver to load, or a piece of "freeware"
software
to compile; something that would have taken minutes on an HP-UX server.
And
support from RedHat is a joke! The quickest response I've gotten so
far to
a reported problem was 72 hours (usually it's 2 weeks, one question has
been
pending for 3 months no with no response). Luckily we bought 1 year
of
support from HP for one of our Linux servers; I can get an answer from
HP
fairly quickly. So far we have very few Linux servers so I haven't
gotten
overwhelmed----yet. However if I had 20 or so linux servers to
maintain,
and everytime I had to make some sort of change to that server I had
to
spend hours recompiling the kernel or whatever...the situation could
quickly
become a nightmare.
I wondered what some of the other HP Sys Admins out there think about
Linux?
Have your experiences been positive or have you experienced some of the
same
difficulties.
Thanks for any feedback.
