Brian,

Have you configured your Qube to use a static IP address or are you 
using DHCP?

I use a static IP address on my Qube. Here are the steps:


1. Set the IP address for local DNS lookups by typing:

echo 'your.ip.address	your.full.name	hostname' > /etc/hosts

2. Check the startup log to verify the name of your Qube's primary 
Ethernet interface by typing:

# dmesg | less

Look for lines that contain an Ethernet address. One of them should 
mention something like tlp0. Then, set the IP address of the Qube's 
primary Ethernet interface by typing:

# echo 'inet your.ip.address netmask your.netmask' > /etc/ifconfig.tlp0

Note that the netmask is written in hex (e.g., 0xffffff00) instead of 
as a dotted quad (e.g., 255.255.255.0). This information will come from 
your ISP or guidelines that govern private networks. If your home 
network operates in the 10.X.X.X or 192.168.X.X address spaces, you'll 
most likely use "0xff000000" or "0xffff0000", respectively, as your 
netmask.

3. add "auto_ifconfig=YES" as a line by itself to /etc/rc.conf

4. Configure the Qube's upstream gateway. This is the address to which 
it will send packets not destined to your network. If your Qube is on a 
home network, this will generally be the IP address of a NAT device.

echo 'your.gateway.ip' > /etc/mygate
