I've given up on getting my wireless lan card to work but am now confronted with another networking problem. I'm hoping someone can help. In V9.3, I was able, by some magical process, to assign a fixed IP address for use in my small local network and, at the same time, use DHCP provided by my ISP to go outside my local network to the Internet. I don't seem to be able to "do the magic" under 10.0. I'm either missing a critical step or the system has been changed. Here's my setup:
My local network is Ethernet and is implemented with a Linksys router switch. The router switch connects to the cable via a cable modem. I've loaded SUSE 10.0 on a non-critical laptop. The laptop connects to my lan via a PCMCIA 10/100 Ethernet card. (If you need any technical details, let me know.) At this point, everything is hard wired.
There are three linux machines, but only one running 10.0, on my lan. Each machine's /etc/hosts file have all three of:
192.168.100.10 toshiba.site toshiba 192.168.100.20 linux.site linux 192.168.100.30 camino.site camino
The two 9.3 machine's NICs are configured as DHCP. They can access the Internet and can ping in either direction to/from each other. When toshiba is configured as DHCP, toshiba can access the Internet but cannot ping either of the other machines & vice versa. If I change toshiba to fixed IP addresses, I can ping everything on the local network but cannot access the Internet.
If you see any obvious mistakes in there, please let me know. If you have any thoughts on how to proceed, let me know that as well. Any assistance will be sincerely appreciated.
I don't see any obvious mistakes but you are leaving a lot of info out of your emails:
1) If the (non-toshiba machines running 9.3) above are DHCP, why do you know for sure what the IP addresses are?
Because I can ping them using either the hostname or the IP address.
2) If the machines in (1) are DHCP, I don't think they would have the addresses you show.
Concur. But I can still ping them using the static IPs.
3) When you change the toshiba to static IP, do you also set a default gateway? (that's what gets you to the internet)
I thought I was but route -n shows: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
4) What is the address of your router? (I assume it's 192.168.100.1)
192.168.1.1
5) What static address are you giving your toshiba?
192.168.100.10
6) When it is DHCP, have you checked route -n to see how the routing (gateway) is set up?
See above. It looks like my gateway settings are being ignored. Here's what route -n shows on linux (V9.3): Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 Observations?
etc, etc, etc.....
