====Creating New Hostnames====

Creating new hostnames simply involves selecting one of the links at the top of the Hostnames and addresses panel and filling out the appropriate fields.

Creating new hostnames simply involves selecting one of the links at the top of the Hostnames and addresses panel and filling out the appropriate fields.

 

Note that if your system is configured with any virtual domains, you will have the choice of the domain in which you want to create the hostname. This allows you, for instance, to have "www.tofu-dog.com" pointing to one IP address and "www.mycompany.xxx" pointing to a completely separate IP address.

This allows you, for instance, to have "www.tofu-dog.com" pointing to one IP address and "www.mycompany.xxx" pointing to a completely separate IP address.

The hostnames you can create on this panel fall into three categories:

Self: Additional names for your server: For instance, you might want to set up "intranet.mycompany.xxx" to point to your server. All you do here is enter the hostname and, if appropriate, choose the domain for the hostname.

 

Additional names for your server: For instance, you might want to set up "intranet.mycompany.xxx" to point to your server. All you do here is enter the hostname and, if appropriate, choose the domain for the hostname.

Remote: As mentioned in the example earlier, you might want to point a hostname such as "www" to a remote system. While "www" is created by default, you can create other names such as "home", "research", or any other appropriate name. In the form, you simply enter the hostname, choose the domain, and enter the remote IP address or FQDN.

 

Remote hosts: As mentioned in the example earlier, you might want to point a hostname such as "www" to a remote system. While "www" is created by default, you can create other names such as "home", "research", or any other appropriate name. In the form, you simply enter the hostname, choose the domain, and enter the remote IP address.

Local: This screen is a bit more complicated because you have more options. At a basic level, you can create a hostname in a domain that points to another computer on your local network. To do this, just type in the hostname and enter the IP address in the "Local IP" field. For instance, you might want "research" to point to a computer system inside your network.

 

Local hosts: This screen is a bit more complicated because you have more options. At a basic level, you can create a hostname in a domain that points to another computer on your local network. To do this, just type in the hostname and enter the IP address in the "Local IP" field. For instance, you might want "research" to point to a computer system inside your network.

Where this gets complicated is when you want "research.mycompany.xxx" to be accessible both inside and outside your local network. The challenge is that your local IP addresses are only accessible inside your network. For that reason, the target computer system will need to have two network interface cards - one connected to the internal network and one connected to the external network.

You would then enter both IP addresses in this screen in the "Local IP" and "Global IP" fields.

{{Note box|The "Ethernet address" field when creating a hostname pointing to a local host is only used for reserving IP addresses through DHCP as mentioned in the next section.}}

{{Note box|At this stage, one cannot create a Hostname under local using a FQDN. However, it is possible to point to a local machine entering the FQDN of this machine as "remote" if this FQDN is valid.}}
