The last line in your /etc/resolv.conf is probably the culprit
because the nameserver 200.224.74.34 is only available when you
are hooked to the net - and evwen then it won't work because
this nameserver doesn't know about your local machines for sure.
Thus bind lookup for your local network is bound to fail.

If you want to use bind you have to set it up locally on one
machine and use it on both machines. In that case it is also
better to use the eth0 address as the nameserver address. So, if
the nameserver is running on rapido, then use 

       nameserver 192.168.1.1

on both machines. BTW, what does nslookup tell you ? Try to look
up rapido and lento by it ! I slowly get the impression that due
to some configuration mistake with named ( believe me, BIND is a
picky beast .... ) it gives wrong answers.

I guess you should track down that first.

For a test you also can disable the startup of named upon boot
so that all your daemons have to rely on /etc/hosts. However, if
a nameserver is running, pretty much all programs seem to prefer
it even if it spits out total bullshit and consequently fail.
Seems to me that this is your problem.

Ping normally works because it does not rely so stupidly on
named....
