First steps into Yoggie Pico firewall

Installed the default Yoggie software and plugged in he Pico stick. It took it about a minute to boot before Windows detected a new device. The driver installation went quite smoothly.

After that, the Yoggie tray icon was failing on my Vista. Also the network usage was blocked when I unplugged the Yoggie stick. I uninstalled the Yoggie software, but the network interface drivers remained on the system, so SSH connection into the Yoggie box continued to work.

The Yoggie software has created a new interface on my PC with the address Guys, you took the whole RFC1918 172.16.* range just for a single point to point link – what a shame. Now I can’t use it inside any corporate LAN which uses these addresses.

OK, now to the interesting part. The device accepts SSH connections on root@, password is “yoggie”. Inside you see a typical Busybox environment.

Here is the guide for the USB Gadget driver that is obviously used insde the Yoggie. It emulates an RNDIS Ethernet NIC. Some info for Linux and Mac users s available at the Gumstix Wiki.

    I have recently got my Yoggie open pico out of a dusty draw only to find the company have gone bust.
    do you have any of the sdk, docs and drivers archived anywhere as the yoggie site is dead now?

    I’ve sold everything to another enthusiast.

    Bother, Thanks anyway. I am having a hard time tracking down the old files. Back to google I guess 🙂

    or just trash it and buy a real embedded board suitable for development. There are dozens of them.

    I have a beagleboard which is much better I just dug this back out on a whim.
