I have a version of slackware installed as a virtual machine and am not able to ping hosts or otherwise receive data from any IP addresses external to the LAN. I think this problem is due to the hostname of the vm not being recognized by the gateway (ddwrt); the vm receives an IP via dhcp but the gateway does not seem to recognize its hostname (registers as *).

Will readily respond with whatever conf file is needed.

First thing to know is what Virtualization product are you using. Another thing to consider is if your Virtual Machine is setup to use a NAT network card or a Bridged network card. NAT will give out a private IP to communicate with the Host machine only. Bridged will obtain an IP from your network DHCP server.

I am using VMWare Workstation 7.0 and my virtual NIC is set to bridged. I should have mentioned in the original post that I can connect via NAT.

It makes Sense that it will work via NAT. When you use NAT vmware will give a private IP address to access the Host machine and other NAT machines. It will then do any external traffic via the Host machine's network configuration.

When you use Bridged, the VM acts as if it is a separate machine and not a VM on the Host machine. Therefore all network traffic is done on it's own with your Physical Network. check your settings in /etc/network/interfaces. You may need to specify a gateway on dns servers.

The file you listed is not present; instead I have listed my rc.inet1.conf and hosts files:

Also here are the results of my ping

PING google.com (74.125.95.105) 56(84) bytes of data.

All of your wireless config settings are commented out. Deleted the leading # on the following lines to make them look like this
Try running ifconfig and see what your IP address is. Looks like to me you are not actually pulling an IP because your network settings are commented out. Interesting thing is that it knows what IP matches google.com even though it can not connect. Do you have a local DNS server?

vmware doesn't (to the best of my knowledge) offer virtualised
WiFi cards to guests. What he wants to edit is the first eth section.
And the gateway
and then the /etc/resolv.conf

What am I to enter into the three sections? Here is my /etc/resolv.conf

Hmmm ... if resolv.conf looks like that you're most likely getting a lease
from a router. Funny that it shouldn't set-up a default route via the
DHCP response, though.


What does 'route' - executed w/o parameters - tell you?



Cheers,
Tink

results of route:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
default DD-WRT 0.0.0.0 UG 0 0 0 eth0


Sorry it took so long to get back.

OK, that's all wrong ... 0.0.0.0 is not a valid IP address,
if your router announces itself as that I'm not surprised
you're not getting anywhere. Looks to me like the router
is misconfigured.

All of the other devices on the LAN receive IPs successfully, including two windows boxes and a debian distro..... I'm considering giving up on Slackware altogether...

Are "all the other boxes" virtualised, too? What's the host OS?

Yes. Might be informative to set DEBUG_ETH_UP="yes" in /etc/rc.d/rc.inet1.conf and see what shows in the logs after reboot or Isn't there a config file to control which parameters are accepted from the DHCP server? Might be possible to prevent accepting the default route using that and configure the desired one in /etc/rc.d/rc.inet1.conf using GATEWAY.

Pardon me. The "other boxes" are actual physical devices.

The host OS for the VM that I am troubleshooting is XP 64.

If the router is announcing an incorrect IP? How can I correct this?

I know this is getting off topic, but I am using a Buffalo WHR-HP-G54 with DDWRT v24. I have just created another vm and the router is announcing itself as 0.0.0.0 there as well...

I may be retitling this thread.
