Dave,

have you thought about bridging?

You can have an IP to the box to telnet into it. There is a bridging
firewall howto to secure your box. And there is a URL for bridging and 
firewalling for 2.2 kernels.

On my RedHat 6.0 system, GLIBC_2.1 and libdb.so.3 are installed
as part of the glibc-2.1.1-6 RPM package.   If you're trying to
install the latest Apache, you'll have to upgrade your system
libraries as well.  This is why you have "failed dependencies".

Cat 3 or 5 are no problem at those distances.  As for 10 or 100  well
how much $$$$$ you got,  go with what you can afford.

>What kind of hubs, patch panels, etc. will I need?

one hub should do it.

>Are there any books/magazines that will help?

10 with no sweat, simultaneously.  Actually many more if you aren't
going to do video, radio and all that crap on all of them at once.  A
33k modem is quite acceptable with 2 users at a time.
56K is a gem with two users.

Books?   Too many to list go to big bookstore and check out which
seems to fit your needs.  (Hint stay away from 'newbie' books on
networking, 500 pages of go heres and theres, no useable info.

The problem is that masquerading does not allows incoming
traffic.  One solution is to install socks5 proxy server - it
supports UDP proxying. You can get freeware socks5 server an
client at  http://www.socks.nec.com. Installation both server
and client is easy.

I need help installing  2 ne2000 compatible netcards
It works fine when I only have 1 netcard in my computer but when I add
the second one in my computer my network goes down :-( 
When I have both netcards in the computer they both show in the first

I used windoze before and never had any problems regarding network. I'm

Any suggestions ?

DO NOT USE the hosts.sam file in the c:/windows dir.  That is a sample
file to use as  a guide.  NOTHING reads it.  You must rename  or
create a text file called simply    hosts     that is filename that is
looked for and at.   Same goes for the lmhost.sam file , progs look
for lmhosts

Are you getting relaying denied? 
Try and telnet x.x.x.x port 25 to see if sendmail is running.
Then make sure you can relay from whatever host you are sending from:
edit /etc/mail/access (sendmail 8.9.2 or later) 
add the following lines
mydomain.com    RELAY # Not really a good idea if the machine in on the new

Please can anyone offer some assistance.  I require to use the
FIOASYNC ioctl in order to ensure that I get IO signals on a UDP
socket.  While I get no error returned, I also get no signals.

I am aware that this has been a recent issue with the Linux kernel,
but as I understand from linuxhq.com, " FIOASYNC (O_SYNC) IOCTL
support" was fixed in version 2.2.5.  I run redhat 6.0, and
uname -a replies

Linux hagal.dcs.ed.ac.uk 2.2.5-15 #1 Mon Apr 19 23:00:46 EDT 1999 i686 unknown

which is the default kernel from the installation.  Surely I've got
the fixes made in release 2.2.5? Do I need to replace my kernel with a
newer one?  Has anyone got asynchronous IO events working with a Linux
Kernel?  Is there something silly I'm not doing right?  Is there an
easy way to check if my kernel is capable of this?

Samba is used for sharing files or printers on which it is installed. For
sharing an internet connection, you need to implement either ip-masquerading
or use some kind of proxy program (such as squid).

Check the mini HOWTO about ip-masquerading that should be found in the
/doc/Howto/mini folder on your RedHat cdrom.

sorry i dont know some of the things you mention ( whats a starmax3000?)
anyway, first thing, try telnet locally
( open a xterm/whatever on your linuxbox, and do
 telnet (name-of-linuxbox)).
if it is NOT working, look for the following:
- is telnet-service started (/etc/protocols or services or something, im
not really sure and cant find out right now)
should normally start along with inetd
- is telnet allowed/forbidden(hosts.allow,hosts.deny)
- look for messages in /var/log/messages

Yup, thats what I was using !
Anywhere in there should be an option to disable the PnP-function of the
card !

By the way - I'm using SuSE 6.1 with kernel 2.2.7 - tried a update to 2.2.10
- compiled the kernel the same way I did with my 2.2.7 - and - NOTHING was

Subject: Critical Firewall Question
Date: Tue, 10 Aug 1999 21:47:58 GMT

I am planning on setting up a firewall for my company.  I have one
running already that uses a private address on eth1.  But for our next
firewall, we don't want a private network behind the firewall.  We want
to put it between our hubs and our T1 to the outside.  Our goal is to
stop all inbound traffic except email.  How can I allow it to filter
traffic while having the real network behind it?  Will the firewall
work if I assign both NIC's REAL addresses?  It seems like that might
defeat the purpose, but we need the real network behind the firewall.
Thanks is advance.

It's certainly feasible and not too difficult, but be sure to read the
sections concerning dhcp servers with multiple interfaces as well as the
part about adding a route to 255.255.255.255 for win9x clients.  I'd suggest
using dhcp only if you've got a significant number of clients, or if you're
just interested.  Be sure to get dhcp2 from www.isc.org. There is also a
mini-FAQ I think...look to http://metalab.unc.edu/LDP/HOWTO/mini/DHCP.html.
