VNC into home server?

Samba - linux mailing list
Hi all,

Usually when I'm travelling I find out that our home server - which runs
MythTV and is therefore a vital part of our entertainment system :-) - has
decided to reboot and hasn't come back up again.  When it's running I can ssh
in to see what it might be doing, but when it's booted but CentOS is not fully
loaded I can't do a thing.

The solution to me is a small KVM device that allows a remote VNC connection,
so I can make that available through my firewall.  Unfortunately, the ones
I've found seem to be a bit expensive:

http://www.adder.com/products/adderlink-ipeps - PS/2?  In this era?

http://rose.com/prod/ultralink2.html

This looks promising - an open board that runs off a Raspberry Pi:

https://www.nexlab.net/product/rasky/

But I can't see any way to buy it there.

Anyone heard of anything else like this?

Have fun,

Paul

Allbids sometimes has enterprise IP kvms for not much money. That said
they're loud and a bit terrible (mine won't work with browsers newer than
Ubuntu 12.04's chromium).

Perhaps an option if you can live with the pain?

That's a charitable donation towards someone's project. Although
deadlines have passed--the page has not been updated to indicate
availability!

Hi Paul,

One solution is to introduce a small KVM.

Another is to treat your existing box as a kind of hypervisor to your
MythTV application.

Re-work the start-up so that you do reliably get an SSH daemon early
(ie. don't require CentOS to be "fully loaded" in order to SSH in).

You know the sorts of issues that you need to resolve when the box
doesn't start - I can only guess.

Some suggestions:
  - don't automatically mount RAID filesystems, or delay their mounting
    until the system is stable.
  - consider putting the "critical" (MythTV) function into a container,
    which can be started manually from the host.

Adding the KVM may introduce more problems than it solves...

cheers,

Bob Edwards.

it's a lot easier to get a 2 x ps2 socket to usb type-a dongle that it
is to get a usb type-a socket to 2 x PS/2 plugs

I've deployed the LANTRONIX spider into a number of remote sites;

https://www.amazon.com/1PORT-USB-Remote-KVM-Spider/dp/B000OH5MDO/ref=sr_1_1

ATEN make a PCI card with RMM function;

Supermicro make  a similar product

Hi Paul,

If I'm understanding you, this is totally doable with a raspberry pi and a
$3 serial port to ttl converter:

2. http://blog.macronet.fi/2016/02/20/raspberry-pi-as-a-remote-kvm/
3.
