Failure of name resolution with ssh on windows 7 and VMware

Failure of name resolution with ssh on windows 7 and VMware

[John Dzielski]

I'm posting again because I failed to provide an informative subject.  
My apologies for the noise.

I have cygwin installed on a VMWare VM running Windows 7 on a Mac 
running OSX 10.6.  This does not seem to be a problem with machines 
running Windows 7 natively.  I am unable to get name resolution to work 
with ssh.  The command ssh X returns the error "ssh: could not resolve 
hostname X:  Non-recoverable failure in name resolution."  The command 
nslookup X returns a valid IP address.  I found the link below, and 
several others that reference the problem, but no solution.  Is there a 
solution to this problem?

I've created a partial workaround in my .bashrc file that creates 
variables containing the IP addresses of the names I need to resolve.  
This solution doesn't work with svn working copies if the repository has 
a dynamic address because the IP address of the repository at checkout 
will be coded in the .svn/entries file.  If the IP address of the svn 
server changes I'm won't be able to perform svn operations.

Run a Wireshark trace when ssh fails and see if you actually have an 
attempt for name resolution. I'd rather suspect UAC or the firewall.

This is a weird idea. Use /etc/hosts for that.

Partial resolution:

I've found that the problem does not occur when using NAT for 
networking.  Bridged mode is still a problem.  I've submitted a request 
to VMware.  Nothing in their database.
