W00t! it worked! First I enabled netconsole just in case. On my Mac (it would be different commands for linux), I opened two tabs in my terminal. In one I opened the read only:
$this->bbcode_second_pass_code('', 'nc -l -u 6666')
In the second tab, I did (with X.X.X.X being the IP address of the pogoplug):
$this->bbcode_second_pass_code('', 'nc -u X.X.X.X 6666')
Then on the pogoplug, I ran the stuff from this post: http://forum.doozan.com/read.php?3,14,14
That is (Y.Y.Y.Y being your desktop with NC running):
$this->bbcode_second_pass_quote('', '[')code]fw_setenv serverip Y.Y.Y.Y
fw_setenv ipaddr X.X.X.X
fw_setenv if_netconsole 'ping $serverip'
fw_setenv start_netconsole 'setenv ncip $serverip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;'
fw_setenv preboot 'run if_netconsole start_netconsole'[/code]
