BUG Command line access
From BUG Wiki
Your BUG is not just a handy device, it's a Linux computer. This means you have command line access, and all of the power that comes with it, to your BUG. You can access the console in a few ways if you have USBnet set up.
Getting to the Console over USBnet
Assuming you've got your BUG networking set up, you can access the BUG via ssh. Linux and OSX have ssh clients built in, just open up a Terminal and execute this command.
Login is root/root.
SSH client for Windows
Putty is a great open source ssh client for Windows (and Linux) machines.
Once connected via telnet you can type help at the (: to see a list of commands available.
Open a terminal and execute this command.
telnet 10.10.10.10 8090
Windows & OSX
Recent Windows and OS X operating systems should have a telnet program with the default install. If you are using a very old version of these OS's, this may help:
Windows and OS X do not have built in telnet clients so you must use telnet within a ssh session to your BUG. Once you have a ssh session with your BUG execute this command.
telnet localhost 8090
