| I am trying to install the 20011205 snapshot on a sun blade 100.
|
| Following the net boot instructions, I was able to boot the
| netbsd.INSTALL.gz kernel over the network.  I found that the
| USB keyboard didn't work, so I switched to use the serial port
| as the console.
|
| With the serial console, it made it to a shell in single
| user mode and I am able to type commands.  It appears from
| the console messages that it found the hard drive etc.
|
| However, I need to do a network install.  So my first step was:
|
| 	ifconfig -a
|
| to see what interfaces exist, and then:
|
| 	ifconfig gem0 inet 199.26.172.170 netmask 255.255.255.224
|
| Using "tcpdump" on a remote machine, I was able to verify that
| some arp packets went out.  Unfortunately, pinging the remote
| machine didn't work.  With tcpdump, I can see that the packets
| are being sent from the sun blade, but for some reason it isn't
| getting the replies.
|
| Furthermore, sun blade is clearly answering ARP requests, so it
| looks like both packet ingress and egress are working at the device
| driver level at least.

I'm not seeing that problem at all.  Make sure your network config
is correct, especially the netmask.

| So I am wondering if there is something wrong higher in the
| TCP stack?  Curiously enough, "ifconfig -a" subsequently displays
| output indicating that the sun blade thinks its IP address is 0.0.0.0,
| although it displays the correct netmask.

That's a known problem with the statically linked ifconfig.  It just
always prints out 0.0.0.0 for the ip address.
