No problem. The diversity of solutions is what makes newsgroups invaluable.
A solution for a small company like ours may not work for a larger company.
Here's why this solution worked for us.
If the T1 goes down, sometimes it could take hours to a day to bring it back
up, depending on the cause. We are not staffed 24/7, so an outage over the
weekend spells trouble for us.
If we reported it Mon am, it is possible that our mailserver has been
unavailable for several days (Fri eve- Mon afternoon, assuming a quick fix
to the T1 problem). A second server wouldn't help in this situation.
Our AV solution wouldn't have helped with the luv virus. It took several
hours for Symantec to release a definition, and a good portion of our
customer base (gov't) was spewing propagation messages wildly.
Our ISP is very helpful and provides a number of addon services to
compliment our own. They are happy to do it, and less overhead for us. For
example, we host our website with the ISP instead of internally. No DMZ
issues, no outage headaches, and most importantly, reduced cost. The cost of
a high bandwidth connection to support a website and all your corporate
traffic vs the cost of having a high bandwidth ISP host your site, and not
worrying about the Sat am calls because the mission critical website is down
is heavily weighted towards using the service of the ISP.
I started and operated an ISP years ago. I sold it when the market was hot.
The early am and weekend troubleshooting gets old really fast :-)
Bounced email happens. It depends upon the resend settings on the sending
server, and the weekend scenario I mentioned could definitely exceed the
typical 48hr threshold.
You are correct in saying that unanswered emails can cause a similar poor
impression. It's sort of like calling a business' telephone number and not
getting an answer. That's bad. But it's worse to call and hear, "...number's
been disconnected..." Lesser of two evils, I guess.
People like you with lots of knowledge and probably lots of resources can
setup redundant solutions and creative configurations, and that's great. It
probably works better. But I get the impression from reading many of the
postings that there are a lot of people here who don't have you degree of
knowledge and are looking for easy, cheap solutions. Call your ISP and in
about 5 minutes you're finished. They'll most likely have it up within a
day. Doesn't get much easier :-)
Our ISP charges $25/month for the backup MX. In my book that's a nobrainer.
Saves cost of server, hassle of outages, etc, etc.
Basically, if you've got the extra server and resources, build a better
solution. Else, some of us operating on a tight budget are looking for
inexpensive and simple solutions.
BTW, I look forward to reading ALL solutions and suggestions for issues,
even though it may not fit my situation. Keep the alternatives coming!

Hey all...
Need some help... BAD!
I have a PIII running Mandrake 7.2 (vmlinuz-2.2.17-21) that I have been
configuring for an internet server. Its been up and running locally for
a few months as I work out some bugs with my PHP scripting. Anyway...
It has a 3 disk SCSI Raid 5 set-up as boot with 2 IDE drives (with raid
1 mirrored partitions). Everything was humming fine, shutdown and
booted fine, until... I was getting ready to haul the box out to my ISP
On Monday, - then I did something... I hit the HIGH security level in
DRAKCONFIG. I thought I had it pretty well secure, but, what could it
hurt? (Hahaha, I found out - LMAO - Sorry, I'm a little over the
edge <evil-g>)
After shutdown, it locked up at lilo init with "LI" as the only display!
I have a boot disk from an old version of RED HAT and can use that to
get in to the system, but no matter what I try, the lilo won't get past
the "LI" without the boot disk.
With the boot disk I can see all of my mounts and root is appropriately
set as /dev/rd/c0d0p1
Here's what I've tried...
- Reset security level to 3, then 0 using msec (nothing)
- checked lilo.conf for anything unusual - nothing
- Re-run LILO - (nothing)
- Checked FSTAB - Looks fine
- Checked permissions EVERYWHERE I could think of... NOTHING!!!
AAAAGGGGHHHH!!! Man I tell ya, I've been up for what seems like years,
I gotta get this thing up and running or I'm toast.
ANY help you guys could lend would be GREATLY appreciated.
(or any ideas!!!)
Thanks... Tedd

Does anyone have a Samsung 900ift working to their satisfaction?
Specifically, I'm having a hard time achieving the reccomended settings
of 1280x1024 85Hz that is recommended.
I'm using a Diamond Fire Gl pro graphics adapter (8 Mb ram permedia 2

Any suggestions would be appreciated

Ok, I wasn't sure about the priorities ('1' for root filesystem
only).
Great stuff about order of processing. That was in the back of my
head too; I don't want to move something onto another partition
that won't be mounted when it's needed on bootup. This tip gives
me good guidance.

No, I understand what you're saying already. The 'ln' option
looks appropriate to my purpose. I'm considering this.
I believe you wrote a message earlier which I missed. I'm going

While I agree that its not too useful, maybe you should have something

When you say you 'redefined' the partition, what do you mean? Did you
make the new file system on it? If you simply changed the partition
type (using cfdisk or similar) there will not be a valid file system.
You will need to create the ext2 file system
