Hi, Zaba,
Thanks for the note!
Note to all on the list: what Zaba and I are discussing is NOT a problem
for those using the CD as it was intended, booting from the CD.
It is ONLY a problem for the 'developers' installing to HD.
Now to continue...I did not knowingly make any change in security when I
updated the disk, so perhaps it was one of the updated Knoppix files.
I would suggest trying the following:
boot up with CD
goto /etc directory for the HD install from there [or chroot it] and the
add zaba to the users list with a notation like:
zaba ALL = NOPASSWD: ALL
or if that doesn't work, perhaps
zaba ALL = (ALL) ALL
Also try adding the line:
Defaults !authenticate
This may not be exactly right as I am at work without Linux, and there are
no guarantees ;)
BUt its worth a try.
I will work on this today and over the weekend as I get time. But I am on
call both Saturday and SUnday and so likely will not get much fun stuff done.
73,
Roger
