I am here in the networking (http://wiki.openmoko.org/wiki/USB_Networking) wiki:
SSH Extras If you get fed up with typing [EMAIL PROTECTED], on your PC edit /etc/hosts and add an entry for 'phone' 192.168.0.202 phone then edit ~/.ssh/config (or create it) and add host phone user root then all you need to do is type # ssh phone To avoid ssh added a new line for every ssh host-key to you known_hosts you can add the following to the phone section in ~/.ssh/config UserKnownHostsFile /dev/null My question is, what does the tilde mean in the filename: ~/.ssh/config I think I have to create this file, but am a bit apprehensive about creating .ssh/config in the root directory. That directory/file does not presently exist there. Thanks! George ----- Following is my current log of networking activities: Neo-Networking 10-24-2007: Attempt to establish basic network connection to Neo. Running Ubuntu 7.10 (gutsy) >From the wiki: http://wiki.openmoko.org/wiki/USB_Networking#Automatic_method Edit /etc/network/interfaces file (): 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 & Completed as root. Patch /etc/udev/rules.d/85-ifupdown.rules: Ubuntu feisty appears to have a bug where ifdown is not run when the interface is unplugged, meaning this only works once after the system is booted. One can patch /etc/udev/rules.d/85-ifupdown.rules, editing the two lines at the end of the file: SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start" GOTO="net_end" LABEL="net_start" # Bring devices up and down only if they're marked auto. # Use start-stop-daemon so we don't wait on dhcp ACTION=="add", RUN+="/sbin/start-stop-daemon --start --background --pidfile /var/run/network/bogus --startas /sbin/ifup -- --allow auto $env{INTERFACE}" LABEL="net_end" ACTION=="remove", RUN+="/sbin/start-stop-daemon --start --background --pidfile /var/run/network/bogus --startas /sbin/ifdown -- --allow auto $env{INTERFACE}" the bug is that the LABEL="net_end" is after the ACTION line in the distribution. I checked my gutsy file. It was wrong, so I changed it as root to the feisty specification above. I restarted the computer.
