<title>Common Errors</title>
<para>
-Stuff from mailing lists here
+File, Directory and Share access problems are very common on the mailing list. The following
+are examples taken from the mailing list in recent times.
</para>
+
+ <sect2>
+ <title>Users can not write to a public share</title>
+
+ <para>
+ We are facing some troubles with file / directory permissions. I can log on the domain as admin user(root),
+ and theres a public share, on which everyone needs to have permission to create / modify files, but only
+ root can change the file, no one else can. We need to constantly go to server to
+ <command>chgrp -R users *</command> and <command>chown -R nobody *</command> to allow others users to change the file.
+ </para>
+
+ <para>
+ There are many ways to solve this problem, here are a few hints:
+ </para>
+
+ <procedure>
+ <title>Example Solution:</title>
+ <step>
+ <para>
+ Go to the top of the directory that is shared
+ </para>
+ </step>
+
+ <step>
+ <para>
+ Set the ownership to what ever public owner and group you want
+ <programlisting>
+ find 'directory_name' -type d -exec chown user.group {}\;
+ find 'directory_name' -type d -exec chmod 6775 'directory_name'
+ find 'directory_name' -type f -exec chmod 0775 {} \;
+ find 'directory_name' -type f -exec chown user.group {}\;
+ </programlisting>
+ </para>
+
+ <para>
+ Note: The above will set the 'sticky bit' on all directories. Read your
+ Unix/Linux man page on what that does. It causes the OS to assign to all
+ files created in the directories the ownership of the directory.
+ </para>
+
+ <para>
+ <programlisting>
+ Directory is: /foodbar
+ chown jack.engr /foodbar
+
+ Note: This is the same as doing:
+ chown jack /foodbar
+ chgrp engr /foodbar
+
+ Now do:
+ chmod 6775 /foodbar
+ ls -al /foodbar/..
+
+ You should see:
+ drwsrwsr-x 2 jack engr 48 2003-02-04 09:55 foodbar
+
+ Now do:
+ su - jill
+ cd /foodbar
+ touch Afile
+ ls -al
+ </programlisting>
+ </para>
+
+ <para>
+ You should see that the file 'Afile' created by Jill will have ownership
+ and permissions of Jack, as follows:
+ <programlisting>
+ -rw-r--r-- 1 jack engr 0 2003-02-04 09:57 Afile
+ </programlisting>
+ </para>
+ </step>
+
+ <step>
+ <para>
+ Now in your smb.conf for the share add:
+ <programlisting>
+ force create mode = 0775
+ force direcrtory mode = 6775
+ </programlisting>
+ </para>
+
+ <para>
+ Note: The above are only needed IF your users are NOT members of the group
+ you have used. ie: Within the OS do not have write permission on the directory.
+ </para>
+
+ <para>
+ An alternative is to set in the smb.conf entry for the share:
+ <programlisting>
+ force user = jack
+ force group = engr
+ </programlisting>
+ </para>
+ </step>
+ </procedure>
