It turns out that shellx was the target of the attack that affected the Bellevue Co-Location facility at Isomedia.  They have black-holed the IP address of shellx to protect the rest of their customers and as a result it was necessary to change the IP to bring shellx back into service.

In the process of doing so, I discovered some missing software and configuration issues that are potentially security affecting and so am working to correct those.  After that is done I will need to take the machine down for 25 minutes or so to image it.
