SSH access during automated install?

Hi list, I successfully installed my suse 9.2 servers via PXE boot, autoyast and an XML file. Now one of the machines seems to have trouble during the install - it just hangs (perhaps a bug in my test xml file). To avoid this in situations where I have no physical access to the machine I tried: usessh=1 and sshpassword=password as kernel parameters. (just to have a "backdoor" to reset the machine if it hangs...) When I now start an automated install the machine boots but WAITS for the ssh user to log on and start yast by hand, which isn´t quite practically during automated install ;-) How do I get access via SSH during install and still have fully automatic install? Thanks for your help! Daniel
