I've installed perl 5.8.6 in the home directory of my website host's server and am having trouble accessing the network and internet with it.

DBD-mysql fails with error Unknown MySQL Server Host 'db1.int.myhosts.com'. Using the IP address I got by pinging the mysql server, I can connect OK.
The site-installed perl at /usr/bin/perl works OK with both the IP address and the url.

CPAN fails to download anything. By changing lib/5.8.6/Net/FTP.pm to force Passive mode, it works OK.
The site-installed perl works OK.

My first thought was that it's something to do with the hostname setup.
I've compared the hostname / domain in both my Config.pm and the site-installed Config.pm - they are identical.

I attempted to download a file from a CPAN mirror using the wget program. It works OK with a http url, but fails with a ftp url for the exact same file.
This suggests it might be firewall issues, but doesn't explain why the site installed perl is having no issues.

I'll reply to this node with the output of some tests, so as to not overload this with too much data.
