You're still using named-xfer? Why not just use "dig axfr" or the
Net::DNS module?

OK, so the O'Reilly book can't keep up with the named-xfer code.
Surprised? I guess you're using Third Edition of "the book", since Fourth
Edition documents return codes up to 6. Even so, the BIND 8.3.3 version
of named-xfer defines a return code of 7, so even it is out of date.

Well, I guess named-xfer _should_ generate an error message whenever it
exits with a value of 3 (otherwise known as XFER_FAIL), but there are no
guarantees. If you can identify under exactly what circumstances
named-xfer fails to do so, then I'd suggest filing a bug report.
