PREREQUISITES

- A decent Perl distribution (IO::Select, etc). Tested with Perl 5.005_03, 5.004m7 and 5.004_04, all run without warnings
- The Net::DNS module

USING DEBIAN

This couldn't be easier:

> apt-get install jdresolve

No need to download anything by hand, as jdresolve is now a Debian app. That'll install any dependencies too :) Debian kicks ass.

USING THE RPM PACKAGES (RedHat, Mandrake, etc)

Just use the following commands:

> rpm -Uvh perl-Net-DNS-0.12-1.noarch.rpm rpm -Uvh jdresolve-0.6.1-1.noarch.rpm

USING THE .TAR.GZ OR .TAR.BZ2 PACKAGES (Any distro)

To install the Net::DNS module, fetch it from a CPAN mirror (http://www.cpan.org), or use the CPAN module to do it automagically.

Using the CPAN modules is simple. You can run it from the command line or interactively:

- command line: perl -MCPAN -e "command"
- interactive: perl -MCPAN -e shell

To keep you Perl distribution updated, you should issue command like "install Bundle::CPAN" regularly. Here is some sample output:

       [root@xhost /root]# perl -MCPAN -e "install Bundle::CPAN"
       CPAN: LWP::UserAgent loaded ok
       Fetching with LWP:
         ftp://cpan.if.usp.br/pub/mirror/CPAN/authors/01mailrc.txt.gz
       Going to read /root/.cpan/sources/authors/01mailrc.txt.gz
       CPAN: Compress::Zlib loaded ok
       Going to read /root/.cpan/sources/modules/02packages.details.txt.gz
       Scanning cache /root/.cpan/build for sizes
       Fetching with LWP:
         ftp://cpan.if.usp.br/pub/mirror/CPAN/modules/03modlist.data.gz
       Going to read /root/.cpan/sources/modules/03modlist.data.gz
       MD5 is up to date.
       File::Spec is up to date.
       Compress::Zlib is up to date.
       Archive::Tar is up to date.
       Data::Dumper is up to date.
       Net::Telnet is up to date.
       Net::Cmd is up to date.
       Term::ReadKey is up to date.
       Term::ReadLine::Perl is up to date.
       CPAN::WAIT is up to date.
       CPAN is up to date.

So for jdresolve to work, you should at least issue an "install Net::DNS".

After that just go back to where you unpacked jdresolve and run './configure' and then 'make install' as root.
