hello.

I feel a little embarrassed about asking this question
because I suspect the answer is staring me in the face
but here it is:

the situation:

2 pcs connected via USB Wireless adapter.

host pc has dialup ppp connection to ISP,
and has gentoo and windows 2000 installed

client pc has fedora FC3 installed.

client has no problems accessing internet
if I use win2k on the gateway.

however, if without changing anything else,
I then switch to gentoo on the gateway,
client can only ping internet using IP (a.b.c.d) addresses;
it cannot ping internet using domain names
UNLESS I put the actual IP addresses of my ISP's nameservers
into client's '/etc/resolv.conf'

(client can of course 'ping bigbird' if I put

big_bird 192.168.0.1


in client's '/etc/resolv.conf').


question:

what am I not doing on my gentoo gateway host that is
causing this problem?

thank you.

You need to setup DNS forwarding. Emerge named.

Also, the following guide may help (not specifically for Gentoo):
http://enterprise.linux.com/enterpri....shtml?tid=100

Alternatively, you may be able to setup your DHCP server to issue the
ISP nameservers (probably better).

Maybe it will help to narrow the range of possible answers if I show
how I start the wireless interface:

1. on the gateway:

a. execute shell script
-------------------------------------
# commands common to host and clients:

iwconfig wlan0 essid boogaloo
iwconfig wlan0 nick big_gentoo
iwconfig wlan0 mode ad-hoc
ifconfig wlan0 192.168.0.1 netmask 255.255.255.0 up

iwconfig wlan0 key off
iwconfig wlan0 key <password>
iwconfig wlan0 key restricted

sysctl -w net.ipv4.icmp_echo_ignore_all=0

# commands specific to hosts:

sysctl -w net.ipv4.ip_forward=1

# for dialup connections, this goes in /etc/ppp/ip-up.local:
#iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

# this should be the last line in this file.
-----------------------------------------------------

b. start dhcpd

c. start named


2: on the client:

a. execute shell script
--------------------------------------
# commands common to host and clients:

iwconfig wlan0 essid boogaloo
iwconfig wlan0 nick little_fedora
iwconfig wlan0 mode ad-hoc
ifconfig wlan0 192.168.0.3 netmask 255.255.255.0 up

iwconfig wlan0 key off
iwconfig wlan0 key <password>
iwconfig wlan0 key restricted

sysctl -w net.ipv4.icmp_echo_ignore_all=0

# commands specific to clients:

route add default wlan0
route add default gw 192.168.0.1

# this should be the last line in this file.
----------------------------------------------

b. make sure named is *not* running.

What I am trying to figure out is,
specifically what is windows 2000 doing when it is the gateway that
gentoo is not doing when it is the gateway
and specifically how do I make gentoo do that?

This isn't needed since the client has a static ip.

Did you configure named at all? If not you need to look at the guide I
offered earlier.

Oops. I meant to say '/etc/hosts'.
