Kind regards

Thanks that works but it doesn't like it if the file is empty. I guess I can do my standard grep nameservers | wc -l to check if there is an entry first.

desproxy-dns

desproxy-dns(1) 						   User Commands						   desproxy-dns(1)

NAME

       desproxy-dns - DNS for dynamic connections

SYNOPSIS

	  desproxy-dns dns_server proxy_host proxy_port

OPTIONS

       None

DESCRIPTION

       If you have direct DNS access then you don't need to do anything else.  You know you have direct DNS access if you can resolve host names
       to IP addresses.

       NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if
       you are running UN*X, you actually have to run desproxy-dns as root).

       OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network
       accordingly (again, need to be root in UN*X).

       Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works.

ENVIRONMENT

       None.

FILES

       None.

SEE ALSO

       dnsproxy(1), ping(1)
