[Nfdump-discuss] nfsen patch for reverse DNS/whois

[Brian C. <b.c...@po...>]

This is a tiny patch for nfsen - unfortunately the bug tracker on 
sourceforge doesn't seem to let me create a new ticket there.

It fixes a problem where if a site has no reverse DNS, the whois data is 
missing. This is because of the text "<not found>" which is inserted 
into the output unescaped, so the browser treats it as an HTML tag.

Regards,

Brian.
