Yes, considering the guy was talking about Linux, talking about postfix
running on FreeBSD is cheating a small bit. I see no reason why Linux couldn't
do the same, but anyways, a standalone box for a mail server is probably
impractical, especially for that many users

OK, now that you've heard references to the religious issues, I have
a slightly different take on the matter.
Find a good mail admin, and give her the tools she likes best.
For 500K users, you aren't talking about trivial administration
no matter what tool you're using, and the conversion is going to
be interesting no matter what. This is not a job for someone
who has never administered a *nix mail system before, so you are
going to be dead if you don't have a wizard admin. And wizard
admins are subtle and quick to anger, so don't tick them off by
telling them what to use based on asking a Usenet newsgroup.
Hire a good admin, pay her for her expertise, AND LISTEN TO HER
because you are, after all, paying her for knowing more about
mail adminsitration than you do.

You don't say what kind of SCSI bus you have (Ultra, Ultra-Wide,
Ultra-2, etc.)
Cable length limits for non-LVD busses can be pretty short:
Fast-SCSI: 6m
Ultra-SCSI: 3m
Ultra-Wide SCSI: 1.5m
Ultra2 (LVD): 12m
Ultra3 (LVD): 12m
If you mix different device types on a single bus, your overall limit is
the tightest limit of all the devices.
So, if you mix a Fast-SCSI device (like a CD-ROM) and an Ultra-Wide
device, your limit is 1.5m.
The reason you may only notice this under heavy load is because your
host adapter will switch bus speeds to the slower speeds when accessing
slower devices. Tehcnically, (in my hypothetical scenario) the limit is
6m when accessing the Fast-SCSI devices and 1.5m when accessing the
Ultra-Wide devices.
In reality, however, this doesn't really work. Even if the Ultra-Wide
devices are close to the host adapter on the bus, the terminators are
separated by more than 1.5m.
I found this exact problem on my system. I've got a 2940UW card with an
Ultra-Wide hard drive, a Zip drive, a CD-ROM and a tape drive.
Normally, they'd all work well together. But when accessing both the
Zip and hard drive at once (copying a lot of files), I'd start to get
errors and bus resets.
Moving the slow devices to a separate bus (I installed a 1542B card that
I had lying around) fixed the problem. Now the Ultra-Wide devices is on
a bus all by itself, where the cable is shorter than 1.5m. And the
three Fast-Wide devices are on a separate bus, where the cable is
shorter than 6m.

Subject: Restaurant Booking System
Date: Mon, 28 Aug 2000 15:45:36 +0100
Hello, All
Apologies for cross-posting, but I felt the need to do this in order to gain
the greatest level of responses from the Linux Users.
I work for a restaurant chain based in Glasgow, Scotland, and we would like
to introduce some form of online restaurant booking system to our website.
We have already had consultations with a company who specialise in this kind
of system, but one of their stipulations is that every time a booking is
made from our website, we are to be charged a fee. Our MD would like to
avoid having to pay such a fee, and with the introduction of higher speed
connections, we are considering introducing our own webserver, and therefore
we would be able to host our own programs and back ends to the website.
What I would like to know is are there any linux based applications
available out there that would allow online bookings, and hopefully would
also allow this to be done for multiple locations. Each of the locations
would also need access to every other unit's booking sheets so that they
could pass bookings on to other sites if they were full for that period. We
are also looking at bringing in a team of dedicated telephone agents to also
take bookings over the phone, but this could obviously be done via the web
front end.
Any advice anyone could provide would be greatly received.
Many Thanks
Darren Paxton

I'm new to using Linux, and had a few questions. I'm building a
Linux file server, on a small home network. I haven't even installed Linux
on the server yet, as I'm having some dificulty with hardware issues at the
moment. But here is what I plan to do.
I have two Windows 98 clients, and want to use the Linux box to
store my files, etc.. I'd also like to add some security to the linux box,
so only my wife, and I have access to the files. I was wondering which
how-to's would help me set up the system in this way? Thanks for your time.

I see only 0x7f's and 0x80's in the file.

Andrew!
I'm new to Linux and even newer to sendmail, but figured aliases were
the solution to this issue - it's nice to know the "right" answer every
once inawhie. :) Per what I've read, and your comments
above, I'm wondering if I can use aliases for an e-mail I send out
monthly. It's not spam as everyone who receives it has requested it
and we follow the mass-mail guidelines. But, this e-mail goes to
between 6,000 and 7,000 addresses. Would it be possible to create an
alias (as in one) for blocks of 1,000 or 500 addresses? Since I'm new
to Linux, I don't know what optimization would be needed to handle a
load like that. Are there better solutions? We maintain the database
manually (it's in access right now) so we don't need automated
subscribe/un-subscribe, and it's just a one way mailing once a month--
not a discussion.
Thouhts?
Thanks!

Maybe stick to 3 or less next time. You've only just scraped below my

Is this in addition to the set up costs? Just out of interest how much
were they charging you?

I would actually _not_ recommend this from a commercial point of
view. When you consider how cheap web space is you would be far better
off IMO letting someone else do that for you. Do you really want to be
dragged out of bed at 4 in the morning after a mains spike or
whatever? �150-�200 a year gets you some nice web space with someone
else to do the donkey work. Compare this to �4-500+ to set up your own
box on a shoestring and doing all your own support.
On the other hand if you want to set up a web server for the fun of it
and you're prepared to learn a lot then go right ahead.

You just need a central database (MySQL/Postgresql) with all the
bookings on it.
IMHO the most sensible course of action would be a web based solution
with PHP. Chances are something like this has already been written and
would just need a bit of tarting up. In any case it wouldn't be so
hard to write from scratch. Just needs reasonable planning and all
that.

Yes, you just need a few admin type pages so that your telephone

Thanks for the suggestion.
Any way, my understanding is that if I can list some files
in the /dos directory, it means that the file system is
mounted.
I checked xvmount which directs to /etc/xvmounttab ( Debian
2.2 Linux Kernel 2.2.14 ). It shows:
#
# Config file for xvmount (v3.5)
#
# name device directory type options
Floppy0: /dev/fd0 /mnt auto defaults # floppy A
Floppy1: /dev/fd1 /mnt1 auto defaults # floppy B
CD-ROM: /dev/cdrom /cdrom auto ro # CD-ROM
DOS-HD: /dev/hda1 /dos vfat defaults # first DOS partition
---
I also checked into /etc/mtab:
/dev/hda3 / ext2 rw,errors=remount-ro,errors=remount-ro 0 0
proc /proc proc rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0
/dev/hda1 /dos msdos rw 0 0
---
I can list part of the files available in the /dos partition
of the hard-disk. But not all of them. I think the question
in fact is more Linux related then Wine.
Any way, any suggestion are welcome.
Thanks,
Jose

Don't think its possible to run Windows, install Mandrake
and wipe the whole partition off.
Use your windows to make a bootdisk, restart and boot up
with your newly created bootdisk. Insert your Mandrake CD
and run from there.
Now that should work - remember to make your Windows bootdisk
with System (or what ever they call it)

Subject: RedHat 6.2 - init doesn't start Apache
Date: Mon, 28 Aug 2000 17:14:20 GMT
Hello,
If this is posted to the wrong group, I'm sorry. It doesn't seem like an
Apache problem, but rather an init problem.
First of all, I initially installed RedHat 6.2 without Apache. I then
downloaded the most recent Apache binaries and installed them into
/usr/local/apache
When I run '/usr/local/apache/bin/apachectl start' Apache starts up
perfectly.
So I decided to add it to the init startup to get it to start
automatically.
I created the file /etc/rc.d/init.d/apache as specified in the Linux
>From Scratch How-to (modifying paths as needed).
I then used 'chmod 755 /etc/rc.d/init.d/apache'
Now I can run '/etc/rc.d/init.d/apache start' and apache starts
perfectly.
Next step (AFAIK) is to add symbolic links to the rc?.d directories for
the appropriate runlevels. Once again I consulted the How-to and created
the following symlinks:
/etc/rc.d/rc2.d/S50apache -> /etc/rc.d/init.d/apache
/etc/rc.d/rc0.d/K50apache -> /etc/rc.d/init.d/apache
/etc/rc.d/rc6.d/K50apache -> /etc/rc.d/init.d/apache
I now tested the system (again) by executing these symlinks, making sure
Apache started and stopped as expected. Again no problems.
Now as far as I know, this is all I have to do to make init start apache
for me when the system boots, however it doesn't happen. Did I miss
something here? I don't think I have to change /etc/inittab, but I could
be wrong.
Thanks!
