The DOCTYPE is incorrect. According to
http://checkstyle.sourceforge.net/config.html#XML%20Details, the checker
configuration file should say something like this:

<!DOCTYPE module PUBLIC
"-//Puppy Crawl//DTD Check Configuration 1.2//EN"
"http://www.puppycrawl.com/dtds/configuration_1_2.dtd">


What happens below is that Checkstyle tries to validate the configuration
file against a DTD. The System ID you are using is not registered with the
XML parser, so the parser tries to download the DTD from puppycrawl.com.
This fails, probably because you'd have to use a HTTP proxy to access the
internet from your machine.

Note that once you correct the DOCTYPE definition, the corresponding DTDs
are built in to Checkstyle and it won't try to phone home.

Cheers,
Lars
