dnsshow

This command lets you view information about DNS settings from the file /etc/resolv.conf.

The command returns all entries in one string, separated by a space. If an empty string is returned, the DNS settings are not configured.

Settings

<InfoKind> = nameservers|search – type of information that you want to view. Possible values:

nameservers – display the list of DNS servers.
search – display the list of search domains.

Example:

> ssh klconfig@10.16.98.17 dnsshow nameservers

> klconfig@10.16.98.17’s password:

10.64.64.5 10.64.16.3

KLCONFIG OK

Specific errors
