bind-tools is quite useful for performing advanced DNS queries. The
'dig' command is especially useful if you want to see the full rrset
being returned. It also lets you set various flags on the DNS request,
and manually override the DNS server.

For casual usage, bind-tools is probably unnecessary.

Yes, that works. Thanks Mike. I'll set up a nice short alias for it. Looks 
like I can get rid of net-dns/bind-tools.

The "order" directive in /etc/host.conf only works for very old
versions of glibc. Modern versions use /etc/nsswitch.conf. The default
nsswitch.conf will check /etc/hosts (files) before DNS anyway.

How are you testing? I would guess you are probably using the wrong tool.

The "host" command will always ignore /etc/hosts. It always does DNS
queries by design.

Try using "getent hosts [hostname]".

[gentoo-user] DNS resolver doesn't

2017-08-08 Thread Peter Humphrey 
Hello list,

On two machines, I have my DSL modem set as DNS server, and it forwards to 
my ISP's servers. This works well for external hosts. I also have "order 
hosts, bind" in /etc/host.conf, but even though both machines have full LAN 
host names and addresses in their /etc/hosts, every DNS lookup goes straight 
to the modem, which of course knows nothing of the local layout.

What else do I have to do to make host.conf effective? Would a hammer help?
