UNIX for Advanced & Expert Users

Hi Felas

I am running Fedora and have this issue on my system:

I have the following users:

jane:x:552:100::/usr1/users/jane:/bin/bash
jules:x:553:100::/usr1/users/jules:/bin/bash

I have the following group which all users belong to:

lab:x:100:root,jules,jane

I have the following folder with appropriate permissions:
xrf/jobs/t000

drwxrwxrwx 3 jane lab 4096 2012-06-26 10:40 xrf
drwxrwxrwx 39 jane lab 4096 2012-08-01 16:05 jobs
drwxrwxr-x 3 jane lab 36864 2012-08-03 15:46 t000

When a user jane creates a file in t000 for example 00001.
this file automatically gets the following permissions:

-rwxr-xr-x 1 jane lab 1060 2012-08-03 15:46 00001

User jules cannot write or access this 00001 file. That is my problem.
How can user jules also automatically access this file without changing
permissions manually each time a file is created?

Regards

in the login directory for each user: jules, jane

1. Create a .profile file, owned by that user, if one does not exist
2. Put (or add this):

Code:

umask 002

Unless a umask setting occurs elsewhere, or an application specifcally calls open() this will work. open() will create files with a locally defined umask.

u mask wont work, I have

umask 002 t000 but nothing


Can you explain what I should do on the user profiles . profile
clearly?

thanks

First off, what shell are they using? It might not be ~/.profile depending on what shell it is.

As for what to do to the profile file? Simply add the line umask 002

You can test whether the umask got set properly by touch /tmp/filename and seeing if it ended up with the right permissions

Seeing that both jane and jules are in the same group;

Code:

chmod g+s <dir name>

setting the sticky bit, aka, groupid, for the directory.
This forces the subdirectories and files to inherit the group perms of the parent directory, which you set accordingly.

Adding another layer, you could implement ACL's (Access Control Lists)

The above link has good info in it.

My google search was "chmod g+s directory". Lots of hits.
