328 Chapter 14 ClusterCATS Utilities
Using hostinfo
The hostinfo utility is a network management tool that displays information about a
specified domain name. Use it to analyze and troubleshoot problems you are having
with DNS mappings to a particular domain.
Syntax
Invoke hostinfo from the command line in the <CC_install_directory>/
program/directory using the following syntax:
hostinfo [fully_qualified_host_name]
Specifying a fully qualified host name is optional. If you do not specify one, then
hostinfo returns information about the current host.
Sample output
The following sample output from the hostinfo utility provides information about a
set of round-robin DNS host names.
>hostinfo allaire.com
Information for host ’allaire.com’:
FQHN: allaire.com
Primary Address: 0.0.0.0
Domain: .com
Aliases:
allaire.com
www1.allaire.com
www2.allaire.com
www3.allaire.com
Addresses:
205.181.25.81
205.181.25.82
205.181.25.83
The hostinfo utility displays the domain name, the primary IP address, and any IP
aliases. If the primary IP address is set to
0.0.0.0, the domain is using round-robin
DNS. The round robin names appear under the Alias section of the DNS table and
the round-robin addresses appear under the Addresses section.
