Subject: Simple network config. Just cant get it right!
Date: Tue, 09 Feb 1999 01:36:10 GMT
Hi all, I've got a list of questions about the various files
necessary for a simple manual (no dhcp) network configuration
(which I still dont have working). My setup is simple, just one
intel machine with a cable modem and ethernet card (which is
supported by 2.0.36 and works fine). If I ever get this all
figured out, I'm going to write a COMPLETE how-to!!!
Note that this is my network info from my provider:
Host: CS373959-A
IP: 24.65.228.72
Subnet Mask: 255.255.255.0
Gateway: 24.65.228.1
Nameserver 1: 24.64.2.33
Nameserver 2: 24.64.2.34
Domain: cghh1.ab.wave.home.com
For each file which is seemingly pertinent to my network setup,
I have listed what I have and any questions or comments that I
have about it. PLEASE give me any feedback abouth anything
wrong or any misconceptions that I have!!!
========================================================================
/etc/HOSTNAME
========================================================================
CS373959-A.cghh1.ab.wave.home.com
# I assume that I should have my FQDN here, but should
# I be using "IP.domain" or the "host.domain" format using
# the host id that @Home assigned to me (like shown above)??
========================================================================
/etc/hosts
========================================================================
127.0.0.1 localhost
24.65.228.72 CS373959-A.cghh1.ab.wave.home.com CS373959-A
# I assume that this is a correct entry for the loopback, and that
# a loopback entry IS required. I am guessing that I should also
# have an entry for my static IP address too.
========================================================================
/etc/host.conf
========================================================================
order hosts, bind, nis
multi on
# I guess this is probably OK, but will having "nis" in there
# screw anything up if NIS isnt being used???
========================================================================
/etc/networks
========================================================================
# Do I need a loopback entry here? Do I need an entry for my
# ISP's network? Note, I am not connecting to any network
# other than my ISP.
========================================================================
/etc/resolv.conf
========================================================================
search cghh1.ab.wave.home.com
nameserver 24.64.2.33
nameserver 24.64.2.35
# I'm not sure that I really need a "domain" or "search" entry
# here because there are really no other machines on my
# network that I'd like to access by hostname alone.
# I dont suppose having it should hurt anything. A strange thing
# I've noticed is if I enter a domain of cghh1.ab.wave.home.com
# using the RH5.2 netcfg GUI, that it puts the entry in this file
# as a "search" and not as a "domain". How come?
========================================================================
/etc/sysconfig/network
========================================================================
NETWORKING=yes
FORWARD_IPV4=yes
HOSTNAME=CS373959-A.cghh1.ab.wave.home.com
GATEWAYDEV=eth0
GATEWAY=24.65.228.1
# I assume that the default gateway device is just my ethernet
# adapter "eth0". I assume that the packet forwarding is
# required but am not sure why. When would you NOT want it?
========================================================================
/etc/sysconfig/static-routes
========================================================================
# Do I need any static routes? Should I put in a static route
# entry showing my adapter/network/netmask & gateway?
# I guess I could add an entry here, but it seems that this info
# would be redundant to the eth0 initialization in the next file...
========================================================================
/etc/sysconfig/network-scripts/ifcfg-eth0
========================================================================
DEVICE="eth0"
USERCTL=yes
ONBOOT="yes"
BOOTPROTO="none"
BROADCAST=24.65.228.255
NETWORK=24.65.228.0
NETMASK="255.255.255.0"
IPADDR="24.65.228.72"
# Now something could be screwy here... The info I was
# provided says that my IP is 24.65.228.72, subnet mask is
# 255.255.255.0, and gateway is 24.65.228.1. Since my IP
# is 24.xx.xx.xx, I assume that my network is a CLASS A
# network. They specifically told me that it was a SUBNET
# mask though, so I also assume that this network is
# subnetted. So I guess my big question here is, should
# the entry in this file show a NETWORK=24.0.0.0, with
# a NETMASK=255.0.0.0 (which I think is the main network
# info) or do I use the subnetted info as currently shown
# in the file above?????
OK. One last question. Since my nameservers are (I guess)
on a different subnet (24.64.xx.xx) than my gateway or my
IP (24.65.xx.xx), will that cause any problems locating the
nameservers? No matter what I seem to try, I can never seem
to ping the nameservers!?!?
Well, thanks for any help. I'm ready to do something crazy if
I cant get this mess straightened out, like go back to windoze :(
I need to start getting some real work done!!!!
Thanks a zillion.

One simple option is to add the -dFIXEDMEDIA option wherever ghostscript is
called. (adding to 'Extra GS options' in the printtool should do it).
It only took me about 20 hours of research to find this landscape fix. I

Subject: Please Help: Redhat 5.2 + DHCP
Date: 8 Feb 1999 19:42:18 GMT
I'm trying to set up Linux DHCP to work with MediaOne's cable modem
service. I've identified several potential problems, but being new to
Linux, I'm not sure which ones are important and how to cure them.
Setup: Redhat 5.2 on AMD K6-2 with 64M RAM and 4.2G HD.
The Ethernet card is a 3COM 3c509B-COMBO, ISA (which I used in other
systems and which works just fine).
The card is identified fine on bootup: the proper driver is used
(3c509.o), the io and irq are fine, and even the 10baseT port is used
(after I used a DOS tool to configure the card to default to 10baseT).
In Control-Panel->Network Administration->Interfaces, eth0 is set to use
dhcp, as it should be. The problem is, it doesn't work either on bootup
or when I try to "activate" the interface from the control panel after
bootup.
Here are some potential problems. I'd appreciate if someone could explain
to me if they really are problems and how I could fix them:
1. The /etc/conf.modules file contains the correct line for eth0:
alias eth0 3c509
However, when I do "modprobe -c" I get two statements that seem to nullify
each other:
...
alias eth0 3c509
...
alias eth0 off
...
The first one comes from /etc/conf.modules. But why is the second one
there? Is it telling my computer not to load the driver for eth0? But it
seems like the driver is loaded anyway, if I'm to trust the bootup
messages...
2. At bootup, when it says "Using DHCP for eth0..." it immediately
follows that with something like "eth0: Setting Rx mode to 1 address". Is
this correct? Or should the card be in promiscuous mode?
3. I called MediaOne, and they claim that they can actually see the
requests made by my dhcp client, and that their server actually assigns me
an IP address and sends me a reply. However, if I use tcpdump, I don't
see any packets on the ethernet after dhcpcd makes its request (of course,
I do see the requests themselves). There are no firewall rules on my
computer to prevent me from receiving those packets (as a matter of fact,
the default policy for both directions is "accept", and there are no other
rules.) Shouldn't I be able to see all packets on the network using
tcpdump? That is, even if my dhcp client doesn't do the right thing with
them, shouldn't I still see the server's responses?
I've been trying to get this thing set up for a couple of weeks already,
and I'd really appreciate any help.
Thanks,
Mikhail

Subject: Help with cable modem and two netcards
Date: Mon, 08 Feb 1999 20:07:34 GMT
I just got a cable modem and it is currently routed through my Linux box
with a 3Com 3c595 and a Netgear FA310TX to a Win95 machine through a
100BaseT hub. The cable modem comes in on the FA310TX, and the internal
network is on the 3c595. For some reason though, Linux will only connect to
both networks when these cards are in the machine. If I use either one of
them with either of two NE2000 cards (Linksys LNEPCI II and a SOHOWare
ND4300) connected to the cable modem, Linux wont ping anything on the
internet, but can still access the internal network. All the cards are
detected fine and I can ping the cards themselves. Anyone know what might be
causing this? Thanks for any help.

Subject: Re: Mascerading & Ip Adresses
Date: Tue, 09 Feb 1999 01:45:59 GMT
This is the line that needs to be changed:
FW_LOCALNETS="195.34.152.0/30 192.168.2.0/30"
The 30's after the slashes indicate that you are using 30 bits to
identify the networks, which only leaves the last two bits to assign to
hosts on each network. This means that only host addresses 1-4 are
valid, with 4 being reserved for the local broadcast address. (This is
why 4 will not work as an address for a particular host.) While this may
be what your ISP intends for the external network, you will need to
lower this number for your internal network (24 is the easiest to use.)
If you do use 24 you will want to change the subnet masks on your
machines from 255.255.255.252 to 255.255.255.0.
Good luck,
Walt Cardwell

Subject: TCP/IP data flow
I have a small home lan consisting of a few pc's
conencted with 3com 3c905/3c905-b 10/100 PCI cards to an 8 port 3com hub
with CAT-5 cable. I am using a linux fileserver (2.2.1) running Samba
2.0
and Windows95/98/NT clients. I notice when transfering files (from a 98
machine to the Linux fileserver)that the hub will light up
to about 50% utilization for a few seconds then drop off to 1% for a sec
and then back up to 50% again in a cycle. Both machines are
using the same ethernet cards (3c905), and the same hard drives
(SCSI-3 Cheetah's). Is this normal or is there something I have to
adjust to get a steady stream of data going?

Why not leave all of your machines on? I have seven machines on a small LAN
at home. I leave all my boxes up 24x7.
It does not make much sense to have a network and not have all machines
available at anyone time. I know you are using yours as a gateway/router to
the outside, and that seems all the more reason to leave that box up.
Yes there is APM support in the 2.0.36 + kernel if you compile it in.
All I do is turn off my display after logging off a box. I rarely even turn
on the display on either of my servers since I usually just telnet in and do
what I want or export the display to the client box that I am on. I don't
have my disks spin down or anything as I always disable the power management
features anyway.
I do have a UPS for each system mainly to absorb power fluctuations but in
the event of a power outage it gives me enough time to cleanly bring down my
boxes.
By the way my oldest box is over four years old same disks et all, and has
been purring along minus planned downtime for moves and other system
maintenance without a hiccup. I did replace a CPU cooler and the case fan ,
but only as a proactive measure.
have fun

This is what I have and it works fine. Perhaps some of those options need
to be outside of the subnet declaration or maybe you at least need the
server-identifier. Give this a try.
server-identifier gw.at.home;
option domain-name-servers 192.168.13.1;
option domain-name "at.home";
option routers 192.168.13.1;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.13.255;
default-lease-time 86400;
max-lease-time 259200;
subnet 192.168.13.0 netmask 255.255.255.0 {
range 192.168.13.20 192.168.13.254;
}
Hope this helps,

You need to select the option 'Prompt for development and/or incomplete
code/drivers' from the submenu 'Code maturity level options' before
since this driver is marked being experimental.

Not a good idea. Is your ISP going to give you 4 valid ip addresses. Mine
will, but I have to pay an extra monthly fee for each ip address. (yuk)
So, what do you do?
Take the linux box and put two ethernet cards into it (eth0 and eth1).
Connect eth0 to the cable modem (might require a cross-over cable but I
doubt it). Connect eth1 to the hub along with the two power macs. Save
your money and buy a 10Mbps hub unless you need the power macs to talk to
each other at 100Mbps. Remember, the cable modem can at most give you
4Mbps download (never seen it go that fast, though).
The linux box will need to be configured to masquerade your internal
network behind the eth0 interface. This means that a packet that comes
from the internal network has its header rewritten so that it appears to
come from the linux box. The linux box keeps track of which packets it
rewrote and for whom (power mac 1 or 2). Read the Masquerade HOW-TO.
Finally, on your internal network, be sure to use the IANA-reserved test
network numbers (see RFC 1918). In your case, let me suggets:
linux eth0 - ISP assigned ip address
linux eth1 - 192.168.1.1 netmask 255.255.255.0
power mac1 - 192.168.1.2 netmask 255.255.255.0
power mac2 - 192.168.1.3 netmask 255.255.255.0

Managed devices are devices like routers, switches, hubs, etc. that
provide some kind of interface (you can telnet into them) or diagnostics
(they are SNMP aware).

Once you have masquerade working, you could but don't have to set up a
proxy on the linux box. My suggestion, get masquerade working first and
then decide if you need/want a proxy server. You don't need Samba or
anything else to get the power macs to talk through the linux box to the
internet with TCP/IP.
Once you've got everything happily surfing and pinging, read the Firewall
HOWTO and lock down your linux box! Once you are on 24x7, you will be
probed.
Hope this helps,
Luca
