Name Resolving bug in Open SSH 3.0.2

[Gil Disatnik]

Hello there,
In OpenSSH 3.0.2p1 there is a strange name resolving bug:

/etc/nsswitch.conf shows:

hosts:          files dns

When I am trying to connect to a host that is in /etc/hosts using the 
hostname, ssh tries to first resolve this name using the dns, regardless to 
the resolve order in /etc/nsswitch.conf, if the dns is timeout or the 
machine is not connected to the Internet at this time - this causes a delay 
of 10 seconds before connecting to a neighbor machine... that's bad.
REMOVING dns from /etc/nsswitch.conf solves this problem, however... 
/etc/nsswitch is there to tell which mechanism to go to first...

What do you say?
