==Introduction== | |||
A hostname is a unique name created to identify a machine on a network. In computer networking, a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word or phrase, or they may be structured. | |||
==Configuration== | |||
In Funtoo Linux <code>/etc/conf.d/hostname</code> is the master configuration file for setting a hostname. In OpenRC framework <code>/etc/conf.d/foo</code> is the configuration file for a corresponding Init script <code>/etc/init.d/foo</code>. With the case of hostname, default value in <code>/etc/conf.d/hostname</code> is set to ''localhost'', means when system boots and OpenRC's <code>/etc/init.d/hostname</code> script started a hostname getting only ''localhost'' name. How it looks? In your shell promt this will look in following way, an example for root: | |||
<console> | |||
localhost ~ # ##i## Hello :) | |||
</console> | |||
Let's play a bit with a configuration. Open <code>/etc/conf.d/hostname</code> with your favorite editor and set a hostname of your choice. Below, I will use a real examples of my working test box. | |||
<console> | |||
localhost ~ # ##i## nano /etc/conf.d/hostname | |||
</console> | |||
Let's set it to hostname="oleg-stable.host.funtoo.org". Save the file and restart a hostname service: | |||
<console> | |||
localhost ~ # ##i## service hostname restart | |||
</console> | |||
Now, let's examine our changes, after a restarting a hostname | |||
<console> | |||
oleg-stable ~ # ##i## Hello :) | |||
</console> | |||
Notice, that we seeing a shortened hostname here, and not a FQDN (Fully Qualified Domain Name). Don't be frustrated , this is how default bash promt PS1 set. To get nice promts, please, consult http://www.ibm.com/developerworks/library/l-tip-prompt/ <-- this one should be on Funtoo wiki :) | |||

Introduction
A hostname is a unique name created to identify a machine on a network. In computer networking, a hostname is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication such as the World Wide Web, e-mail or Usenet. Hostnames may be simple names consisting of a single word or phrase, or they may be structured.
Configuration
In Funtoo Linux /etc/conf.d/hostname is the master configuration file for setting a hostname. In OpenRC framework /etc/conf.d/foo is the configuration file for a corresponding Init script /etc/init.d/foo. With the case of hostname, default value in /etc/conf.d/hostname is set to localhost, means when system boots and OpenRC's /etc/init.d/hostname script started a hostname getting only localhost name. How it looks? In your shell promt this will look in following way, an example for root:
localhost ~ # Hello :)
Let's play a bit with a configuration. Open /etc/conf.d/hostname with your favorite editor and set a hostname of your choice. Below, I will use a real examples of my working test box.
localhost ~ # nano /etc/conf.d/hostname
Let's set it to hostname="oleg-stable.host.funtoo.org". Save the file and restart a hostname service:
localhost ~ # service hostname restart
Now, let's examine our changes, after a restarting a hostname
oleg-stable ~ # Hello :)
Notice, that we seeing a shortened hostname here, and not a FQDN (Fully Qualified Domain Name). Don't be frustrated , this is how default bash promt PS1 set. To get nice promts, please, consult http://www.ibm.com/developerworks/library/l-tip-prompt/ <-- this one should be on Funtoo wiki :)
