Locked Out..Had to happen 1 day, I guess

[Mark Sargent]

Hi All,

thought I was changing the permissions for /tftpboot in FC3 with chmod 711 . 
whilst in /tftpboot but, I think I typed ".." instead of ".". I was just, 
well, seeing what the different number sequences did. Guess I just found out 
the hard way. Can't even access via Knoppix3.7,

knoppix at ttyp1[knoppix]$ cd /mnt/hda3
bash: cd: /mnt/hda3: Permission denied

Am I stuffed. No hope..? Heck, what a way to learn something so simple/stupid. 
Cheers.

Mark Sargent.
