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

["Todd Deshane" <deshantm@xxxxxxxxx>]

More things to try:

check /var/log/secure(.log?) or /var/log/auth.log

how did you create the guests? I recall some cases of debian guests not finishing login due to missing the udev package.

Cheers,
Todd

Hello Waldirio:

Thanks for you advice.  I was not aware of strace.  I followed you advice

little cryptic for me so any assistance would be greatly appreciated.

Cheers,

David
