Thanks Till, particulary for the putty advice
The ispconfig system wasn't running, however, I'm now getting another issue. When I try to browse to the admin page now in Firefox I get the following messsage ' Could not establish an encrypted connection because certificate presented by 172.16.169.10 has an invalid signature'. In IE I still get the usual Internet Explorer cannot display the webpage.
The network team have suggested that this is because the certificate was created for OpenSuse1.hope.ac.uk (on their advice) but as we don't have an internal DNS Server (!!!) that address will never be resolved so I need to now create a certificate for 172.16.169.10.
Does this sound correct and how can I do this without being able to access the ispconfig interface?
Thanks again for your help
