putty quits almost immediately, nothing in logs at DomU or Dom0

putty responds with:
   Network error: Connection refused

Then looking at putty event log:

   2011-03-31 20:43:20  Looking up host "192.168.1.xxx" (IPv4)
   2011-03-31 20:43:20  Connecting to 192.168.1.xxx port 22
   2011-03-31 20:43:23  Failed to connect to 192.168.1.xxx:
               Network    error: Connection refused
   2011-03-31 20:43:23  Network error: Connection refused


[On DomU]

tcpdump -nS

   only sees ARP requests / replies when restricted to the
   putty client machine.


The following two lines look the most interesting on the Dom0 machine:

21:21:48.585443 ARP, Request who-has 192.168.1.xxx tell 192.168.1.xx, 
length 46
21:21:48.585686 IP 192.168.1.xx.50847 > 192.168.1.xxx.22: Flags [S], seq 
600018374, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], 
length 0
I've also tried the following [and it's reciprocal]

tcpdump src 192.168.1.xxx and dst 192.168.1.xx and port ssh

Any options that you think I should use to see the "right" detail?


Thanks.
