I totally agree.
How are you connecting to the network? Direct peer-to-peer connection?
Via a hub? If you're connecting peer-to-peer, make sure you're using a
crossover cable. (Been there, done that, bought the T-shirt.) Another
prosaic point, is you're network card supported? If it was
automatically detected during installation, it should be supported. So
you can't ping outside? Can you ping any of the local machines? What
kind of machine is the gateway? If it's a Windows machine, I can't
offer any advice. If your gateway is Linux, you have to have ip
masquerading running on it to allow the other machines in your network
to connect to the awesome internet. What does your routing table look
like? Do a 'netstat -rn'. Here's what the routing table on one of my
Red Hat 6.1 machines looks like:
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface
192.168.1.12 0.0.0.0 255.255.255.255 UH 0 0 0
eth0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0
eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0
lo
0.0.0.0 192.168.1.11 0.0.0.0 UG 0 0 0
eth0
I have a network of three Red Hat 6.1 machines. This routing table
comes from the machine with local IP address 192.168.1.12. The gateway
machine has local IP address 192.168.1.11. It's running ip
masquerading. This machine connects to the internet via dial up modem
(ppp0). I added the gateway to machine 192.168.1.12's routing table
with:
route add default gw 192.168.1.11
The gateway machine does not have a default gateway entry since it
connects directly to the internet. Good luck,
