For now, it's enough to remember that these steps of finding addresses are called hostname resolution, for mapping hostnames onto IP addresses, and address resolution, for mapping the latter to hardware addresses ref.: Linux Kernel Networking: Implementation and Theory by Rosen, Rami 1st (first) (2013) Paperback Two files are created in the /etc directory: /etc/named.conf and /etc/named.boot. Four files are created in /usr/sbin; these files are named, named-boot, named-xfer, and rndc. The file /usr/sbin/named is the name server daemon; named-boot is a Perl script that converts named.boot files to named.conf files; named-xfer is a transfer program for external zone files; and rndc is the name server daemon control program Git Essentials download pdf.

What are the benefits of 4gb fibre channel? Benefits include twice the performance with little or no price increase, investment protection with backward compatibility to 2 GB, higher reliability due to fewer SAN components (switch and HBA ports) required, and the ability to replicate, back up, and restore data more quickly. 4 GB Fibre Channel systems are ideally suited for applications that need to quickly transfer large amounts of data such as remote replication across a SAN, streaming video on demand, modeling and rendering, and large databases. 4 GB technology is shipping today , source: Fedora 18 Linux: Networking read epub read epub.
