Hay,
I am a gentoo 2.6.17 user.
I followed the pinned howto and did managed to get internet over usb:
# /etc/init.d/net.usb0 start
 * Starting usb0
 *   Starting ifplugd on usb0 ...                                         [ ok ]
 *     Backgrounding ...
here is the line:
# fgrep usb0 /etc/conf.d/net
config_usb0=( "192.168.129.1 broadcast 192.168.129.255 netmask 255.255.255.0" )
on my simpad I ran:
   # ifconfig usbf 192.168.129.2 netmask 255.255.255.0 up
   # route add default gw 192.168.129.1
yet I can't ping each other :-(
I tried adding a rule to allow incoming ping to the simpad, and apply it. still can't ping it from my unprotected pc with firewall.
how to fix it?
