4. Are we in yet?

As I rebooted the device, I feared my changes would be overwritten or that the modified password file would be detected by a checksum comparison. If this occured, the NSLU2 could to refuse to mount the drive or insist on re-initializing it.

But as I waited, I heard the familiar beeps from the NSLU2 indicating everything was normal. After re-enabling Telnet, I tried it out:

# telnet 192.168.1.70 Trying 192.168.1.70... Connected to 192.168.1.70. Escape character is '^]'. NSLU2 login: root Password: No directory, logging in with HOME=/ BusyBox v0.60.4 (2004.07.01-03:05+0000) Built-in shell (ash) Enter 'help' for a list of built-in commands. #

Success! I had a command prompt. The ability to get a shell completely opened up the device. I could now review the software and hardware architecture of the box, looking for ways to extend it. Since this device naturally manages a hard drive, it should be possible to place new scripts, executables, and drivers on the box. Time now for the hard work to begin.

In Part 2, I'll go into detail on how to add features to this interesting little box. In the meantime, you can keep up with my adventures on my Linux on the NSLU2 page.
