I've been using Turnkey Linux file server for a few years and I think it is an excellent appliance software. But my hard drive recently crashed and I had to reinstall. I only got around now to try and create user accounts but couldn't remember what I set the login password as. I tried all the usually suspects but none work.
After reading a few sites at Google, I finally found this tip that worked:
Basically, you can manually edit the .htusers.php file of extplorer and change the "admin" password with one that you manually generate using echo | md5sum.
