Thanks for the idea... I may be able to use that somehow. The question now
becomes how to automatically detect this mail upon reception. The best I
can come up with is a cron job that checks for mail every hour and then
deletes all files printed within that hour. Unless there is another way to
automatically detect new mail and spawn a script to read the mail. Is there
someway to use something like the vacation program for that purpose?
Here's the mail from the lpr mail:

So it seems it wouldn't be difficult to parse the subject line for the file
name, but I'm not sure how to automatically start such a script upon
reception of mail.
Any ideas?

Given the problems I've experienced running Windows--both as a home user
and as an IS professional--I was looking forward to giving Linux a
whirl, after all the good things I'd heard about the software.
Unfortunately, my experiences to date don't bode well.
I've been struggling to get my sound card functioning, my printer to
print plain text files properly, and SAMBA to connect me to my NT
shares. I've read the HOWTOS, followed suggestions I received via
various newsgroups (when there was anything the least bit helpful, which
wasn't often) and still haven't accomplished any of the above.
I fully expected a learning curve, but this is becoming ridiculous.
While I have been able to get some things installed and
working--StarOffice, Netscape Communicator--by and large the most basic
of tasks have proved to be a huge pain. Linux may be more stable, it
seems so on the dial-up Internet side of things, but the applications
that run on it crash just as often as Windows applications. And it has
a long, long, long, way to go when it comes to ease of use. Most
everything is far too difficult to configure. Unless, of course, you
have hundreds of obscure commands and hundreds of even more obscure
command options committed to memory. Maybe if I had 5 or 6 months to do
nothing but play with it I could overcome some of these basic obstacles,
but most people could learn to accompish these same tasks in Windows in
a matter of days or weeks. The number one problem may be the lack of a
good HELP system. As faulty as the HELP system in Windows may be, it is
light years ahead of Linux.
I wish Linux good luck, just as I do AMD, but I'm doubtful it will ever
become more widely used than it is currently.

Someone please correct me if I'm wrong, but one would not want DNS for
clients. DNS is required for name resolution for servers providing a service
like FTP, HTTP... If you have a machine providing services like this without a
static IP address, you're nuts. If you are trying to provide DNS for clients
on your network that don't offer services, you're nuts. What are you trying to
do?

Better yet, use ssh instead of rlogin. *If* you really want to have a .rhosts
- at least make sure that it doesn't grow out of control (your control, that
is). If it is located on ufs or ext2 - make it immutable. Or run a cron job
that will purge all unauthorized crap from them and send nastygrams if crap
had been found. User-editable .rhosts is the breakin waiting to happen.

It's a valid choice!
Linux as a workstation has very little use right now, but try it as an very
inexpensive server solution for file/print sharing and even as an
application server (Informix, Oracle, etc.) or as an exceptional firewall!
Good luck!

1- figure out if rlogind is running.
2- if it isn't, install it or SSH.
3- check to see that rhosts.allow has the client machine in it and rhosts.deny
doesn't. Don't think you need an entry for the client machine in hosts though.
4- can't remember, but somewhere in one of root's dotfiles there's a line to
disable root's ability to rlogin. This is generally disabled in Linuces and
the *BSDs but enabled in commercial unices, at least on Irix and Solaris. IMO
it's pretty stupid to allow rlogins anyway.....
that ought to get you going in right direction. if it's not enough, read a
book, a man page, or dejanews archives.

I did it, for my self I've just share it using SAMBA, once install, you only
have to share you'r printer as a SAMBA services.
You probably already have a SAMBA server on you'r linux machine if you want to
see you'r linux machine in your windows neightborhood. Get a look at the
file/etc/smb.conf, you already have an example, you'll probably only have to
uncomment some line to make you'r printer to be shared, once done, just add
the printer to you'r windows computer in adding a network printer... you'r
windows is suppose to reconize the printer...... it as worked ...

Why dial-up? You probably have your reasons, but I would recommend using VPN
solution. For $19.95/mo. (earthlink, netcom, etc.) per user you can open
Internet accounts for all members of your sales force and let them get into
your network via VPN. This way there is no ports limit, they only limited by
your bandwidth, also they could use this solution from out of country. No
worries about phone line costs/troubles, etc.
But if you have set your mind to PPP there is number of solutions offered by
3Com, Multitech, USR, etc.

Date: Sat, 24 Jul 1999 07:34:32 GMT
I have 3 computers sharring one internet connection from a Gateway
computer running Windows98-SE... I have a cable connection...
These computers are as follows:
Windows98-SE ---> Gateway machine
Windows98 ---> machine 2
Windows NT 4 Workstation ---> machine 3
Mandrake Linux ---> machine 4
My Win98, and WinNt machines share the Internet nicely... Very fast...
Mandrake automaticaly set up the shared internet connection on
installation...
My problem is, the speed at wich Mandrake makes the connection is
obsurdly low (as in 1k/sec)... Is there any easy way to fix this... I
know this should be faster cause I had windows95 on this machine before
I installed Mandrake and it was very fast... does it have anything to do
with the MPU packet sizes or something like that? if so how would I fix?
Thanx for any help you could possibly offer!!! =)
