Your network configuration looks good.

The error is

500 Can't connect to www.ncbi.nlm.nih.gov:80 (Bad hostname
'www.ncbi.nlm.nih.gov')

Do you have a browser on your server? Can you reach www.ncbi.nlm.nih.gov?

Or for security reasons you can test this on the console with

telnet www.ncbi.nlm.nih.gov 80

If it's okay this should appear

$ telnet www.ncbi.nlm.nih.gov 80
Trying 130.14.29.110...
Connected to www.ncbi.nlm.nih.gov.
Escape character is '^]'.

If this appears www.ncbi.nlm.nih.gov is reachable and i don't know
where the error comes from.

I wonder myself who produces this output anyway

<HTML>
<HEAD><TITLE>An Error Occurred</TITLE></HEAD>
<BODY>
<H1>An Error Occurred</H1>
500 Can't connect to www.ncbi.nlm.nih.gov:80 (Bad hostname
'www.ncbi.nlm.nih.gov')
</BODY>
</HTML>

Is it bioperl or the ncbi server?
