    <p>The reason why you are not able to execute ls is because of permissions.</p> <p>If you are running the web server as <strong>user A</strong> , then you can only <strong>ls</strong> only those directories which have permissions for <strong>user A</strong>.</p> <p>You can either change the permission of the directory or you can change the user under which the server is running by changing the <strong>httpd.conf</strong> file(i am assuming that you are using apache).</p> <p>If you are changing the permissions of the directory, then make sure that you change permissions of parent directories also.</p> <p>To change the web server user, follow following steps:</p> <p>Open the following file:</p> <pre><code>vi /etc/httpd/conf/httpd.conf </code></pre> <p>Search for </p> <pre><code>User apache Group apache </code></pre> <p>Change the user and group name. After changing the user and group, restart the server using following command.</p> <pre><code>/sbin/service httpd restart </code></pre> <p>Then you will be able to execute all commands which can be run by that user.</p> <p>EDIT:</p> <p>The 'User' should be a non-root user in httpd.conf. Apache by default doesnot serve pages when run as root. You have to set user as a non-root user or else you will get error. If you want to force apache to run as root, then you have to set a environment variable as below:</p> <pre><code>env CFLAGS=-DBIG_SECURITY_HOLE </code></pre> <p>Then you have to rebuild apache before you can run it as root.</p>

    1. COThat didn't quite work - I followed your steps and got an error asking that I add a -DBIG_SECURITY_HOLE CFLAG to the env variables. I'm not too familiar with CFLAGs as they pertain to Apache.

    2. CO@MattS I have edited my answer to explain why you are getting this error. My suggestion is that you run the apache as a non-root user instead of rebuilding apache.

    3. COI changed the user/group to be the administrator user (just below root), and it still didn't work.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
