I am looking to list wisdom to get some direction to help solve this one
first please.
Personally, I wouldn't be leery of upgrading Net::DNS via CPAN at all.
It's probably
better than upgrading perl modules with yum or apt-get, since CPAN is
pretty much
the authority on perl in general.
If you're really leery of using the CPAN shell, or want a more automated
process, I'd
download the source tarball, verify that the manual installation method
works, script
it, and then rsync the tarball/script, and do a over ssh to fire it off.
An example of a script I use to send around qmail aliases would be:
#!/bin/bash
# $Id: syncAliases,v 1.0 2006/11/08 15:18:00 peter Exp $
#
# Synchronize the /var/qmail/alias/aliases file after updates are made and
# rebuild the aliases.cdb from blade1.
cd /var/qmail/alias || exit 1
make all
MASTER=host1
HOSTS="host5 host6 host7 host8"
for h in $HOSTS ; do
scp /var/qmail/alias/aliases root@$h:/var/qmail/alias/aliases
ssh root@$h "cd /var/qmail/alias && make all"
done
Fire it off, pop in the passphraze twice, and let it rip.
For your application, I'd replace the /var/qmail/aliases with
<full_path_to_source_tarball>,
make a script that runs on the local system after sending the file over,
put a line that sends
it over before the tarball or after, and then change the execute line
enclosed in doublequotes
to run that script.
As long as you verify everything works by testing before committing,
there's no reason
you couldn't do 200 servers in not too much over an hour. If you trust
using empty passphraze
host keys (not really considered a good idea), then it could be finished
in a half hour.
