Permissions Problem

[MichaelD]

Can anyone help me sort this out please? lol I've changed the permissions thinking I was granting access to myself as a user to /usr/share/mdk/backgrounds/, but I've locked myself out from most other things in the process.

Now I can only get to my own folder /home/michael. If I try the up button to go to /home, it tells me "Unable to enter file:/home/ You do not have access rights to this location."

What I was trying to do was grant rights to /usr/share/mdk/backgrounds/ so that I could copy some wallpapers over so I added my own rule, but deleted it afterwards.

What are the usual groups for a normal user? I am a member of the "michael" group at the moment.

I've just reinstalled Mandrake 10 after trying redhat so my home location in Konqueror is still set to file:/usr/share/doc/HTML/index.html

However, when I load it, I now get this:

An error occurred while loading file:/usr/share/doc/HTML/index.html:
Access denied to /usr/share/doc/HTML/index.html

How can I restore the permissions?

Security level is set to highest. I did that because I'm setting up a webserver etc. If I drop that to normal or whatever I can get back to that page, but I don't want to alter the security level if I can help it.

What a muppet I am! :o

into a terminal, type:

su
enter root passwd: 
cd /usr/share/mdk
chmod 606 /backgrounds

606 = rw permissions for user and others
1st number = permission for user
2nd number = permission for group
3rd number = permission for other

0 = block
4 = read
6 = read + write
7 = read + write + execute

not dont use the 7 if theres no programs to be run in that directory, best is to use 6.

Thank you very much for your help.

I should really buy myself a dummies guide to Linux or something!

Thanks again.
