I have two PPP dialup accounts. How should I set up the /etc/resolv.conf
file to handle multiple accounts? (They have different domains).
Thank you.

Subject: RH 5.2 and probably routing problem?
Date: Sat, 29 May 1999 15:06:19 -0700
Hi folks, I have a linux box setup with RH 5.2, eth1 talking to the
world and eth0 talking to my internal network. From the box I'm able to
reach the world without any problems. I'm also able to reach anyting on
the internal net without any problems. The problem is, from the inside,
I can ping beyond my linux box to my ISP's gateway and DNS server. Thats
great!!! However, from inside my network, I cannot reach anyone outside
of my ISP's realm. I talked to the ISP, they mentioned that they do not
believe they are blocking packets from going out, and that the problem
is my routing...since I'm new at this, they are undoubtedly right.
Its setup pretty much the same as the firewall HOWTO document. The eth1
talks to my ISP's gateway successfully. The eth0 is setup as
192.168.0.254 with the netmask as 255.255.255.0. On the inside of my
net, I setup one machine as 192.168.0.34 with a netmask of 255.255.255.0
and the gateway as 192.168.0.254, my linux box. As I mentioned above, I
can reach the linux box just fine, and reach the ISP's gateway and ISP's
DNS server just fine. But can't go beyond the ISP. Is the problem that I
need to turn on IP Masquerading?? Is IP Masq. available in RH 5.2, or do
I have to upgrade to RH 6.0 to do this?
Oh, I have also tried starting up routed and I can't get to the world
either with routed running.
I presume the IP Forwarding is turned on. If not, I don't think I could
have reached the ISP through my linux box. Isn't that true???
thanks -- Dean

Subject: Process to replace NIC on RH6.0

X-Newsreader: TIN [version 1.2 PL2]
I need to replace a twisted-pair NIC. I have a ne2000 at irq 5 and memory
address 0x300 . I need to replace it with a 3C509 at irq 10 memory 0x300.
What is the process to remove the NIC from the kernel config, and then
add in a new NIC with irq & memory address?
I tried linuxconf but it only ask for nic type, and I am not even sure
what to put in for my nic. I don't see how to enter irq & memory info.
This in on a Redhat6.0 box, but the process is probably the same for
RH5.2, as I can't seem to figure it out there either.

By typing just : su root
you do get root access but you can not do everything as if you were sitting
at the console. I beleive that the proper command would be : su-
It is not necessary to add the username 'root' as that is exactly (and only)
what the command is used for on a Linux system. The same thing happens (you
are asked for the root password), but you do inherit all the 'goodies' of the
root account. KAS

My friend had the same problem on RH6... It was solved when I added
all the local hostnames and IP's to the /etc/hosts file.
I also added all the local host names and IP's to the c:\windows\hosts
file on the win machines... but I'm not sure if this had anything to do
with the solution.

Subject: New to Networking / Questions about Client-Server Network
Date: Sat, 29 May 1999 22:46:07 GMT
My employer is considering purchase of a network for our office and
laboratory. We have about twelve client systems (some notebooks and some
desktops) running Windows 95 and 98. There are also a few desktop systems
in our lab running MS-DOS 6.2 and Windows 3.1, but they may be soon upgraded
to Windows 9X.
Our business is at a point where shared access to database files for
tracking business prospect development and laboratory sample tracking seems
to demand a file server. We are meeting with a network consultant to
discuss a proposal for a network next week, but he will almost certainly
push hard for NT Server 4.0 and Microsoft Backoffice.
I have almost no experience in working with networks other than as a user.
I have played around with peer-to-peer networking of my home desktop
machine, my wife's PC, and my notebook PC with mixed results. However,
since even my limited experience with networks is above that of my
coworkers, I am likely to become the administrator of this proposed business
network, ready or not. Since my employers are extremely cheap, I expect
that they will not go for NT Server 4.0 and Backoffice. The possibility of
using Linux is appealing, especially its cost (free). Once the NT approach
is vetoed I would like to have an alternative solution to offer up.
My questions are:
1. Is is possible to setup a client-server network system running Linux as
the server OS and Windows 9X on the client systems? If we only use the
server for data file sharing and don't try to run any Windows 9X software
from the server, can this work?
2. Can we setup some sort of intra-office email system with MS clients and a
Linux server?
3. How powerful of a machine would we need for the Linux server (assuming
that the answers to 1 and 2 are yes)? Can we get by with a Pentium II system
with 128 MB RAM?
4. What are some good resources (books or web pages) for guiding us in
setting up amd administrating a Linux - MS Windows mixed network?
I would appreciate any advice or other assistance that could be offered, as
I am new to Linux also.

I'm using rrlogind 2.21 (www.vortech.net/rrlinux/rrlogind.htm), and as far
as I can tell it is logging me into roadrunner. I guess this program is
setup to run as a service on my linux box. I get an [ok] during bootup when
it says logging into roadrunner. I think dhcp is set up correctly, my
ethernet adapter (eth0) is assigned an ip address when I type in ifconfig.
The problem is that netscape cannot find any www servers. I'm guessing I
have to configure the dns server somehow? I hope someone can help!

Is your cable modem spitting out data a lot faster than your network
card can handle them? Then it might help a little to set it to "max
performance". Otherwise you might find some use for that extra cpu power
you get when setting it to minimum CPU use.

Hervey,
More than likely, it's your telco. ADSL is new to them, and they
may have monitoring taps or what-not on your line. I know of one
instance where they couldn't fix the local loop because the test
equipment was ADSL-hostile; every time they went to look at the line,
their test set killed the carrier, and it took 5 minutes to re-sync.
Write a little script that does a traceroute or something like that
every 20 minutes. Let it run for a day or two, and look at the
results. You'll probably find that every now and then you can't even
get "out the door".
If nothing else, you'll find out where it's dieing.
Gary.

I will be setting up an ISP in the very near future. I would like to

I recently installed a LAN in my basement to hook my two Windows 95/98
machines and my one Linux machine together. I got the two Windows machines
running no problem but I am rather new to this whole Linux thing. My Linux
machine is an older 486 and it only has ISP ports so I was forced to use
this ISP NE ethernet card that my friend had laying about. Anyway, I got
the card physically installed but when I tried to install the modules for it
the kernel starting asking me for information such as hardware
configurations and I have no idea where to find what it wants. Can someone
give me a hand or maybe just point me in the direction of an installation
How-to for idiots. (and I do mean for idiots) I took a look over some other
how-to's and they all seemed to skip the very basic stuff that I am having
problems with.

For what it's worth, this Win95 behavour also annoys WinNT.
Download the setup program from 3com. Find a valid configuration for
the 3C509, and nail that down. The setup program will allow you to turn
Plug-&-Pray off, which should prevent the card from squirming around.

In the named.conf file (or named.boot perhaps, depends on version of
named), add the following line at the bottom.
tech.maindomain.com. IN A 123.456.678.123
Notice the . after the .com (it must be there)! Then restart named and
you should be able to ping tech.maindomain.com from outside your
network. If this doesn't work.. the DNS-HOWTO has some examples and
other info that might help you out.
