posadis-getroots - Retrieve root nameserver list to put in your "posadisrc"
posadis-getroots [icann|
This program retrieves an up-to-date list of the root nameservers you can put into your Posadisrc. It has a hardcoded list of root nameservers, which it will try to reach in order to find the most recent information.
The program can, at your choice, either query the standard, Icann (www.icann.org) root nameservers, or another root server organisation. To try one, type its name, or, to enumerate all available root nameserver sets, use a nonexistent root server set, for example, none. Alternatively, you can specify your own DNS server that should be queried.
The resulting list of root nameservers will be printed to standard output in a form suitable for inclusion in the posadisrc file for Posadis. If an error occurs, an error message will be printed and the program will return with a nonzero exit code.
