You could instead setup a local forwarding DNS server that calls out to
the real server. That way it'll timeout immediately when you're offline.
Setting up is easy. Just use this for your /etc/named.conf (this is my
copy):
---------------------------------------------------------------------
// generated by named-bootconf.pl
options {
directory "/var/named";
forward only;
forwarders {
198.9.200.100;
202.54.1.30;
};
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
//
// Boot file for name server
//
// type domain source file
zone "." {
type hint;
file "named.root";
};
// Zone boot information and daemon options are kept in other files
// (autoincluded from boot.zones)
//
// Name server zone boot file
// See named(8) for syntax and further information
//
// type domain source file
// (autoincluded from boot.options)
//
// Options for name server
// Use `bindconfig' to automatically configure this file
//
// type domain source file
zone "localhost" {
type master;
file "named.local";
};
zone "127.in-addr.arpa" {
type master;
file "named.rev-local";
};
// Custom configurations below (will be preserved)
------------------------------------------------------------------
Note that you can have only two forwarders. Any more and they'll be
ignored. I use the first for my local DNS server which works only for
the local network, and the second for Internet resolutions.
