lcfg-resolvconf - An LCFG component to manage the resolv.conf file
This documentation refers to lcfg-resolvconf version 0.100.3
An LCFG component to manage the resolv.conf file
For a complete discussion of all the options see resolv.conf(3)
The list of IP addresses for nameservers, you can have as many as you like in here but normally only the first 3 will be used by the resolver.
Lookups for hosts within this domain can use short names. This defaults to the value of the profile.domain resource. If unset the resolver works it out from the local host name. Note that the domain and search keywords are mutually exclusive, if you define both only the search field will be added to the configuration file.
The list of domains to search for the hostname. This can be up to 6 domains with a total of 256 characters. By default it is the value of the profile.domain resource. If unset the local domain name is used. Note that the domain and search keywords are mutually exclusive, if you define both only the search field will be added to the configuration file.
This can be used to instruct the resolver on how to sort the addresses returned. There is no default value.
Not all resolvers support the rotate option. This is a boolean value which signifies whether the component should randomize the server list before putting it into the configuration file. The default is false.
This is a list of options which will be put into configuration file. By default it is all the options listed below:
A boolean value, default false.
An integer, default 1. This sets a threshold for the number of dots which must appear in a name given
An integer, default 5. This sets the amount of time the resolver will wait for a response from a remote name server before retrying the query via a different name server. Measured in seconds.
An integer, default 2. This sets the number of times the resolver will send a query to its name servers before giving up and returning an error to the calling application.
A boolean, default false. Setting this to true causes round robin selection of nameservers from among those listed.
A boolean, default false. Setting this to true disables the modern BIND checking of incoming hostnames and mail names for invalid characters such as underscore
A boolean, default false. Setting this to true has the effect of trying a AAAA query before an A query inside the gethostbyname(3) function, and of mapping IPv4 responses in IPv6 "tunneled form" if no AAAA records are found but an A record set exists.
The file to be configured, this defaults to /etc/resolv.conf. You probably do not need to change this resource.
This is the template file to be used, it defaults to /var/lcfg/conf/resolvconf/template. You probably do not need to change this resource.

This is the list of platforms on which we have tested this software. We expect this software to work on any Unix-like platform which is supported by Perl.
Fedora13, ScientificLinux5, ScientificLinux6
Please report any problems (or praise!) to bugs@lcfg.org, feedback and patches are also always very welcome.
