After doing a bunch of different crap to my N800, mainly cloning the OS to the SD card, but also installing stuff from the command line (apt-get install) I rebooted to discover that sshing to the unit produced the error: "stdin: is not a tty." Puzzled, I rebooted again with the same results. I attempted to open up an xterm and the xterm window opened, but never dropped to a prompt. WTF?

Googling revealed that this can be caused by problems in your .bashrc file, but since the N800 uses ash, I hadn't created one. Again, WTF??

Rebooting to flash, I mounted my internal SD card (where OS2007 lives), and low and behold, something (not me) has created a .bashrc file in my root directory. There was not a .bashrc file in my /home/user directory.

Deleting the /root/.bashrc file restored the ability to ssh to my N800 and made xterm usable again. I post this just in case someone else encounters this problem.
