ssh: connect to host eisner.decuserve.org port xxxxx: Network is unreachable

Greetings. Is there some down-time scheduled that I missed? Or is there really some network problem?

TIA!!!

Once again, EISNER is hung.

However, this one is pretty strange, because when I connect to the remote
console, ^[^[rmc does not seem to do anything.

Unfortunately, there won't be anyone near its hardware to do an actual
power-off/power-on until Tuesday.

Thanks for the word!

EISNER is back up now.

What VSI need to do is to build a remotely-controlled servo project
that pushes in the power button on the Alpha when activated. :-)

$ set response/mode=serious

Alternatively, VSI could always look at the US version of something
like this:

for a long time, and this was the first one I found when I went looking
for a specific product just now.

IOW: do your own research before buying one. :-)

I've seen it done with an old PC and a piece of wood glued to the front of
a CD tray.

depending on the alphaserver model then there may be RCM available so if the console serial port was connected to a terminal server then the alphaserver can be powered on remotely

I suggested the hardware approach because the RCM method didn't work for Rob.

Several years ago, I had a similar need for some x86 gear. I
designed a board that provides, effectively, a set of
electrically isolated, serial-controlled solid-state switches.
I used a USB adapter for the serial device, and the "switches"
are really just optocouplers connected to an LED driver
controlled by a microprocessor. A short Molex cable assembly
connected the optocouplers to a daughter board mounted on a
PCIe connector with a slot cut in it; then headers on the
daughter board connected the optocouplers in parallel with the
frontpanel reset and power switches. A little daemon written
in Go serialized access to the serial interface and exposed a
simple RPC protocol for command-line tools to request resetting,
turning on, turning off, or power-cycling individual machines.

This worked pretty well. The way the power and reset switches
on ATX power supplies work, pushing one of those buttons just
shunts a small signalling current, usually pulled high on a
sense pin, to ground; so I only need to turn on a coupler for
a few seconds at a time. I don't know how this compares to the
power circuitry on an Alpha, though; I imagine it's somewhat
similar, and you can drive this thing from anything that speaks
USB and serial (e.g., a Raspberry Pi).

Of course, if you need to reset the entire power supply,
something like a remotely programmable PDU is still necessary,
which would provide functionality equivalent to toggling the
rocker switch on the PSU.
