Re: [Xen-users] ssh between DomUs in Xen3.2

["Waldirio Manhães Pinheiro" <waldirio@xxxxxxxxx>]

    Hello David

  Let's try fix this problem. In the second machine, which work fine, on link http://rafb.net/p/1HnPnm90.html at line 408 you can see, the client received the string "SSH-1.99-OpenSSH-3.9p1\n" and continue the process normally, at the firts machine http://rafb.net/p/SRoQE434.html at line 310, the client hang up at this point.

You may test with the command #telnet 192.168.17.201 22, which normally you will receive a answer like below

[root@cerberos ~]# telnet 192.168.0.11 22
Trying 192.168.0.11...
Connected to 192.168.0.11 (192.168.0.11).
Escape character is '^]'.
SSH-2.0-OpenSSH_4.3

Protocol mismatch.
Connection closed by foreign host.

PS: Probably you will be a delay to show SSH-2.0-OpenSSH_4.3 string, so ..., your problem.

I had this problem with WindowsXP 64, which there aren't ssh server with support to arch 64, however, try re-install or update your ssh server.

Good Luck
