How to Manually Mount a USB Flash Drive on Redhat Enterprise Linux

1.       Login as a root redhat Enterprise linux or Centos distribution then enter the appropriate password when prompted.

2.       Enter the command lsusb at the command line.  Thankfully for Plug-N-Play, your computer should recognize your USB drive. 
3.       If it does not, try plugging into another USB drive and re-issuing the lsusb command. 

4.       Look for the device assignment.  Generally, this is done by ‘searching’ using the dmesg command.  After issuing the dmesg | grep ‘disk’ command, I found my device assignment as shown in the output /dev/sdb.

5.       Now, let’s create a folder in the Linux file directory to act as a mount point for our USB flash drive.  I am going to create a folder in the /mnt directory called /usbflash’ by issuing the "mkdir /mnt/usbflash" command.

The xinetd Super Server

Not all services have their own initialization script for starting, stopping, and checking the status of the daemon. Some network services are controlled by xinetd, also known as the super server. Running services through xinetd allows the administrator to utilize xinetd features such as access control, custom logging, and the incoming connection rate. The xinetd service listens on all ports used by the daemons it controls. When a connection is requested, xinetd determines if the client is allowed access. If the client is allowed access, xinetd starts up the desired service and passes the client connection to it. The xinetd RPM package must be installed to use this super server. If it is not, install it via Red Hat Updates.
Configuring the xinetd Server
The xinetd super daemon uses the /etc/xinetd.conf file as the master configuration file and the /etc/xinetd.d/ directory for configuration files per service controlled by xinetd. This section discusses how to use these files to configure xinetd and its services.
