Permissons to upload to directory and read directory

Hi,

I'm having a problem setting permission for a directory using Unix, telnet.  I want to upload using a php script to a directory.  I then want to allow the user to browse this directory so i need to have the permission to read it.

Could someone give me the instructions for this.  Sof far i've been using:-

chmod o-rx output
setfacl -m user:nobody:-wx output
chmod g+w output

But it's not worked.

Since the apache process likely runs under the nobody user, and this will not be in the same user group as your home user, you will need to give world read and write rights to access the directory.  I cant be sure of this, since I dont know how your server is configured, or what users/groups are in play, so here's a strategy to find the correct permissioning model.

Start with some slack permissions such as:

   chmod 777 output

Then use the following commands in order, to find the tightest permission set that works for your server configuration:

   chmod 776 output
   chmod 766 output
   chmod 744 output
   chmod 744 output

When you find one setting that will not allow either your upload or your browsing, revert to that last one that worked.

Note - Don't bother with 'setfacl' unless you know exactly what you are doing, and remove any setfacl settings you have already created.

sorry - typo:

   chmod 776 output
   chmod 766 output
   chmod 764 output              <-  corrected
   chmod 744 output

others has rx permission to a dir does mean they can read the files inside the dir!

the file permisions must be readable for others as well.

if the dir is for the webserver, and you want to allow the users can read the file in the shell (telnet, ssh login etc). the file permsions need to be:

755 (for scripts)

assume that you set:
assume that out owned by fred and belong to nobody group
chmod 755 output
chmod g+s

in your php script, you need to set umask to 022 before upload the file to make
sure all the files are readable to the others.

If you want to use ACL, please have a look at the links (tutorial in):
