This software use only basic functions like <i>gethostbyname(3)</i>
|
|
or <i>gethostbyaddr(3)</i>. Checkresolv use the more low-level
|
|
of the resolver galaxy, so it works like any "lambda"
|
|
application. Really nice when you have to catch a mysterious
|
|
failure in a <small>LAMBDA</small> software.

The environmemt variable <tt>CHECKRESOLV</tt> control the verbosity.
|
|
A value of <tt>tech</tt> add the display of reverse lookup and timings.
|
|
And setting to <tt>all</tt> give you all the bells'n'whistles needed
|
|
by geeks.
