The hotel I'm staying at has a new and stupider-than-usual setup:  its 
DNS intercept mechanism replies from a different IP address *and port 
number* than the one to which NetBSD sent a query.  Until I got to view 
their obligatory advertising Web page, I couldn't get out to the rest 
of the net -- and NetBSD wouldn't resolve the IP address of their 
redirect site because of the aforementioned idiocy.  I could probably 
have hacked the resolver library, but I'd had a bit too much ethanol at 
dinner to want to do that.  Is there any configuration or resolv.conf 
setting I could have used?  I had to reboot to our favorite insecure 
operating system, just to get past the nonsense, before I could use the 
Internet.  This didn't amuse me...
