New cables
Since the systems have been moved to another position, the cabling for monitor, keyboard and mouse weren’t long enough to connect to the server, so I ordered extension cables/ For keyboard and mouse, I envisioned that USB extensions would do, and this one came with build-in amplifiers. But nothing happened, so I decided a reboot – which failed: there were user files open on two disks and that meant these could not be dismounted, and the system became overloaded – for no appetent reason. Tried to stop some processes but the system became slower and slower. CTRL_P, and crash (to find out what was going on) was required. After restart it became clear that there was a TCPIP process that took all CPU and caused excessive paging.
But the system started without a hitch – almost: after upgrading WordPress (to a new directory) I forgot to change the logicals for the blogs. Done that by hand so it now all works again.
There is one more short downtime to be expected, when I change power tomorrow.
The USB extensions don’t work so I have ordered the normal PS2 extension cables. the USB extension have found good use by moving the printer and scanner, and now I have some more room on the workplace to add more machines.
