I have a directory on my server which has several people that can write
to
it. Each person has their own username but they all belong to the same
group. I would like to make sure that every file and directory that is
created in that directory are group-writable. In other words, if Rita
(member of group psacln) creates a file or subdirectory, then Ginger
(also
a member of group psacln) should be able to write to it or delete it, and
vice versa.
The way to achieve group collaboration is to have new files and
directories
become the group name of the group, not the default group name of the
creator. Also, new files and directories need to have the group's
write bit set. Here are the commands:
1) sudo chmod g+wxs .
2) sudo chgrp psacln .
3) sudo echo umask 0002 /etc/profile
The key is the s-bit set on the directory. This has the special meaning
of setting new files' and directories' group name to the group name
of the directory, not the creator.
The umask command says to always turn on the group's write bit for new
files and directories.
All of the users are members of the group psacln and when they create files
or upload them via FTP, the files have the correct group assignment.
However, even after going through the steps you outlined above, new files
are not created with the proper permissions.
When I FTP test.test with
Rita's account, the file has permissions -rw-r--r-- set. I need it to be
-rw-rw-r--
The group-write bit is probably not set on the file on the local
computer.
Try setting that first, then FTP. Umask doesn't set any bits not already
set.
Also, FTP may not source /etc/profile, first -- I don't remember.
Consider using scp (or sftp). You first need to:
1) cd /etc/pam.d
2) sudo vi sshd
== session optional pam_umask.so umask=0002
3) sudo vi login
== session optional pam_umask.so umask=0002
TAR files are another problem. The group-write bit must first be set.

I think you're looking for http://en.wikipedia.org/wiki/Setuid The other option I'm aware of is to set a umask with group write. I can't recall if this is done in the mount or if it can be done just on the directory. Another option along those lines is to use a package called acl (access control lists) for fined grained permissions.
