Ok, so "a couple of days" was a little optimistic :)
Everything seems to be up and running again now; Gentoo Linux is much less resource hungry than Redhat 9 which is good news - no need to upgrade the hardware yet...
The camera will be offline for a day or two while I upgrade the PC it's attached to. Redhat 9 was looking a little old, so I'm updating it to Gentoo. Going by previous experience, computers are no better than cars for appreciating it when you try and do them a favour, so if it all turns to sick, the camera maybe offline a bit longer than a day or two. We shall see :)
The field in the foreground is planted, like much of Norfolk this year it seems, with Oil Seed Rape, so expect a riot of yellow in the next few weeks.
