Funny, but I don't see the letters "DNS" in the log at all :-)

What does /etc/nsswitch.conf say about hosts? Does "files" come before
"dns"?
If so, what does 
	grep 192.168.17.4 /etc/hosts | head -1
show? Presumably paris.bim.
But what does
	grep paris.bim /etc/hosts | head -1
show?  My guest is *not* 192.168.17.4
