In Short, Dig This

Possibly there's not a sysadmin around who hasn't needed to do a host lookup
now and then, to make sure they know what addresses are really being found
when a DNS lookup is made.
nslookup is deprecated, host can be confusing, dig is the nice tool for the
job - regardless of attempts to claim it is old too, it will be around a
long time. But who really wants to get a long listing full of semicolon
comments and things?

Unless I'm tracking the path of authority rather than just checking the
address, I don't care either.

Short, sweet, and to the point. Replace "a" with "mx" or "ns" as you please,
but this is a lot handier for scripting; I don't have to invoke my talent
for awk and grep one-liners on DNS checks anymore.

DNS proxy/cache (Tip)
Tue, 16 Mar 2004 00:11:33 +0100
Karl-Heinz Herrmann ([55]kh1dump from khherrmann.de)
Hi,
I had an annoying little problem: My home network has grown to 3 PC's -- one
directly on the phone line, the others connected via WLAN. Usually I would
pick one dial-up provider and stick with that. Unfortunately the German
ISP's are a big mess of call-by call providers with constantly changing
tarifs.
The directly connected box is only the dial-in and firewall/NAT Router, the
other two are my Laptop and desktop.
The annoying problem: Everytime I change the provider I had to change the
resolv.conf on all systems according to the new nameservers as transmitted
via [i]ppp protocol.
My solution: dproxy
[56]http://dproxy.sourceforge.net
It serves as a proxy/cache for DNS lookups. It uses regular sys-calls for
namelookups and reacts instantly (no kill -HUP or similar) to new entries in
/etc/resolv.conf. This is on the router of course and everytime pppd changes
the resolv.conf for the new provider it simply uses the new values.
The other two machines have the router as the nameserver and always get the
correct information (even offline, so a connection is of course not
possible). No manual changing anymore.
K.-H.

Sometimes, despite our best eforts with "unzip -L", we end up with a bunch
of files the names of which are ALL IN CAPS. The easy way to deal with these
