I was having a problem with not being able to re-connect to my FR after
unplugging the usb. I'd have to reboot my lappy in order to ssh to the FR. I
saw the fix listed on the usb networking page:
http://wiki.openmoko.org/wiki/USB_Networking
Since I use Ubuntu I changed the order of the code as instructed despite the
comments that it doesn't work. It worked for me.
However, I was checking out the suggested code for /etc/network/interfaces
and it is different from what was posted several weeks ago. I had edited the
original /etc/network/interfaces to this:
----------------------------
auto lo
iface lo inet loopback
auto usb0
iface usb0 inet static
address 192.168.0.200
netmask 255.255.255.0
network 192.168.0.0
up iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.0.0/24 &
up echo 1 > /proc/sys/net/ipv4/ip_forward &
up iptables -P FORWARD ACCEPT &
down iptables -D POSTROUTING -t nat -j MASQUERADE -s 192.168.0.0/24 &
iface eth0 inet dhcp
auto
---------------------------------
This has worked fine so far AFAIK.
However, the current suggested code for /etc/network/interfaces is:
---------------------------------
allow-hotplug usb0
iface usb0 inet static
address 192.168.0.200
netmask 255.255.255.192
post-up iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.0.192/26
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -P FORWARD ACCEPT
pre-down iptables -D POSTROUTING -t nat -j MASQUERADE -s
192.168.0.192/26
---------------------------------
What is the difference between 'auto usb0' and 'allow-hotplug usb0'?
