Yes, it's doable. Check out the IP-Masquerade HOWTO at www.linux.org for
doing this with Linux. You can also check out nat32 for NT.
I use a 486SX25 with 8MB to masquerade a home network of 4 other
computers. I use Debian 2.0, but have also used the LinuxRouter
distribution (http://www.linuxrouter.org).
I would recommend using Linux over NT... this presupposes you are willing
to learn about how to configure linux.

I really hope someone can help me cause IP Masqurading is apparently
what i need to do.
I was looking at the mini HOWTO on IPMasqurading, but it talks about
compiling the
kernal :( I have RedHat 5.2 with the 2.0.36 kernal. Can someone tell me
what i'm supposed to do?
Please. I'm still very new and i wanna get both of my pcs connected to
the net with the one connection
But the linux box will not let me use the eth0 and the ppp0 at the same
time. If i have the eth0 active the
ppp0 will not work, and if the ppp0 is active the eth0 will not work. I
am setting up everything
thru Xwindows cause i'm still fuzzy on all the command line stuff. All
the HOWTO's i read are based
off all the command line things which i dunno. Any way if anyone could
assist me with setting up
my 2 pcs to get connected to the net. Thank you very much in advanced.

I haven't messed with the ftp server yet, however, under RedHat, there is a
file called /etc/securetty which contains a list of users who cannot telnet
to your machine. I resolved this by a 'mv /etc/securetty securetty.old'
(renaming the securetty file) so that the file exists in case I need it in
the future.

The easiest way is to load XWindows, run the control-panel program, and from
there run the network configuration program. However, the configuration
files are stored under /etc/sysconfig/network-scripts
The filename would be something like ifcfg-<device name> example:
'ifcfg-eth0'

Hi,
I have for the last few days tried desperately tried to get PVM
(Parallel Virtual Machine) to work but I am have trouble with "rsh". On
both PC's I have renamed the /etc/hosts.allow and /etc/hosts.deny so
that these are non-existing (granting everyone access to everything - I
know: bad idea). Then I have put the following in /etc/hosts.equiv on
PC-1:
localhost
pc2.homenet
and in /etc/hosts.equiv on PC-2:
localhost
pc1.homenet
but if I try the following (as root): "rsh pc1 ls" on PC-2 I get a
"Permission Denied" and the same on PC-1 (with pc1 replaced by pc2, of
course).
The /etc/hosts is correct (I can use telnet and ftp between the two
machines).
What on earth could be wrong? Any hint/help would be appreciated.
Tanks in advance,
Rene Fosdal

I am an old aficionado of Slackware, using this last 3.6 distrib i
noticed this behaviour happening only after installing redhat rpm
package: - like you my system is looking pretty good: file permission
are OK, so as directories, i had to reinstall slackware again, but could
look around before doing it and shells where ok but for some reason
couldn't be run.
good luck

Using DHCP I'd like to have my Linux box identify network printers so that
the Windows 95/98 machines on our network can use their "add printer"
function to print to network printers. Is there a guide as to how to make
Linux a DHCP server and/or another methodology to have Linux do what Netware
does in making network printers appear on a list that can be found by a
Windows user?

Thanks for your response. It seems as though your suggestion keeps sendmail
from sending mail via smtp all the time. It is convenient if it would send
while I am connected though. Otherwise, I'd have to recall to type
``sendmail -q,'' right?

I'd say the name server choking up is a name server problem. It would
be nice to run a caching name server so I don't have to wait for a DNS
response when going to my favourite sites. If it is locked up, it
incurs a longer wait as programs time out before going to an external
server.
Resolving the sendmail issue is priority, however.

Inetd never starts telnetd. I did an "strace" on inetd and it just sits there.
My /etc/hosts.allow looks like:
ALL : ALL
And if I "tcpdmatch in.telnetd snort" to see if snort (the W98 machine) would
be allowed access to telnet, it says access would be granted.
Any other ideas?

If you need a good book just to get you started I would suggest:
A Practical Guide to Linux
By Mark Sobell with Foreword by Linus Torvalds.
ISBN 0-201-89549-8
This book is a readable textbook to walk you through being a newbie. Its not
a hardcore system administrators book. Its a book that you sit down at the
terminal with and start from logging on and go from there. The truely
remarkable thing is its readablility. And you can fly through the first part
and get a firm grasp on the stuff you need to know down the road quickly.
Truely a beginners guide. Well worth the money.

My hosts.allow looks like:
ALL : ALL
And tcpdmatch indicates the W98 machine would be granted access to the telnetd
service.

You'll probably want to use IP masquerading on your box so it can act as a
gateway/firewall/router, or whatever you want. Read the IP-Masquerade
HOWTO at:
http://metalab.unc.edu/LDP/
Unless you want to get a network card for your linux box and laptop, a
serial cable is just about the only way to go. You could also use a
parallel cable, but I think a serial cable would be simpler. Read the
section in the Linux Network Administrator's Guide (also available from
the above URL) about Slip/Dip. I have set up a connection like that
before, and all I did was read the Dip docs and modify one of the example
scripts to suit my needs.
Good Luck!
