Increase NFS Client Mount Point Security For a Web-Server noexec, nosuid, nodev Options

Posted on in Categories , , , , , last updated February 19, 2014

I am using NFS server version 4.x on a CentOS/RHEL based system. I’m mounting my shared /var/www/ directory on five Apache based nodes using the following syntax:

mount -t nfs4 -o rw,intr,hard,proto=tcp rocknas02:/httproot/www /var/www/

I noticed that due to bug in my app user can sometime upload executable or other device files to get out of chrooted Apache server. How can I prevent such security issues on a CentOS or RHEL based NFS client and sever setup?

Is there command that can give me a list of files that have been added to the filesystem at /var/www/uploads/ in last 7 days on Linux/Unix-like oses?

HowTo: Find a Directory On Linux Based System

Posted on in Categories , , last updated August 25, 2013

I just switched from MS-Windows server admin to Debian Linux server admin role. I need to find a directory called project.images. I was also told that the locate command is the simplest and quickest way to find the locations of files and directories on Linux. But, the locate command is not working out for me. How do I find project.images directory using command line options only?
