Folder Permissions

[JinTexas]

I set up Debian Etch as a File Server on an old Compaq 7470 using Samba. It seems to be working fine except for one problem. I created 4 user accounts and each users home folder is accessible from the Window$ XP machines on the network. I set up a /data/music folder to be accessible by all users. The problem is that this folders is not accessible unless I add the command chmod o=rwx music. I tried the commands chmod u=rwx music and chmod g=rwx. I can see the folder from the XP machines but I can;t write to it unless I add the other users cammand. This is on a home network where I have three Window$ XP machines as well as the Debian file server behind a router. I am concerned about security. Is this something that I should be concerned about I would appreciate any advice!
Thanks,

Here is what I do.

I create a group called say tunes
then I put all the people in my network that needs access to it and I only give them read and execute.

Then I chgrp tunes music
then I chmod 755 music
that gives root all rights and your group all read and execute and O read and execute.

Let me know if you need more clarification.

If you don't want root to have all rights you can chown your username.

Thanks for the advice. Will these commands remove write privaleges to the all 'others' that were given with chmod o=rwx music? I think I understand your instructions. I will give it a try tonight. Thanks again!!!!

yes it will look like this

drrwxr_xr_x root tunes music yada yada

7 rwx 5 r_x

Hi I am having a similar problem with with folder/file accessibility, except it has to do with Typo3. The manual says this:

"Run these commands as root in the cms/ directory:
# chgrp -R <wwwserver> fileadmin typo3conf typo3temp uploads
# chmod -R g+w,o-rwx fileadmin typo3conf typo3temp uploads

... where <wwwserver> is the name of the group your webserver
is running as"

It sounds simple But the main problem is that I am a little new to this syntax and dont completely know how to "Run Commands."

Sorry for redirecting this thread but I found this after a 5 Hour search on the topic and got no real help. All suggestions are welcome. Thanks.

So what does the 755 do? I have seen different numbers following the chmod command. Can someone point me to a list of these parameters and what they mean? Thanks. J

You can substitute numbers for read write execute

7 == all
5 == read and execute and
0 == no rights.

There are others but these are the most common

And it works like this

drwxr_x_ _ _
d == directory
rwx == read write execute
r_x == read and execute
_ _ _ == no rights so this would read

chmod 750

the first three is owner the second set is group and the third is the world.

Does this help?
