Hello All:

I am working with a small cluster running Xen3.2 on Scientific Linux 5 on the worker nodes. I have been trying to mess around with some different network configurations and have stumbled upon something that seems very strange to me. My DomUs can connect with the Dom0 and external network (ping,ssh,etc), I can connect with the DomUs from the head node and Dom0 (ping,ssh,etc) and I can ping the DomUs from one another BUT when I try to ssh from one DomU to another it just hangs.

[root@localhost ~]# ssh -vvv 192.168.17.200
OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003
debug1: Reading configuration data /etc/ssh/ssh_config

And here it just hangs...

In the /var/log/secure file on the vm I am trying to connect to the following line shows up after I <ctrl> c the ssh command:

Jun 12 14:13:03 localhost sshd[2478]: Did not receive identification string from ::ffff:192.168.17.201

I have located the following post that was never responded to. I am not sure if this is the same problem.

http://lists.xensource.com/archives/html/xen-users/2008-01/msg00951.html

I have not modified the xend-config.sxp file so I am using all the default scripts. I have tried this on Xen3.1.0 and I am finding the same problem.

Any help would be greatly appreciated.

David
