Linux KVM software?
Alan Mackenzie
get, with which you could connect up one set of {K V M} to several PCs.
More recently, there's software been developed, by which you can control
a remote computer similarly, with the necessary signals going over
Ethernet. trouble is, all the one's I've seen are restricted to
X-Windows. I want something that works on a remote virtual terminal.
Does anybody know any free software which does this?
Thanks in advance!

I'm not sure I understand your requirements.
Are you looking for an ethernet data-stream equivalent of a KVM switch? That
is to say, a tool that will encode raw video signals from a video card, raw
keypress signals from a keyboard and raw mouse movement signals from a
mouse serial port into ethernet frames, and decode the same on the other
side? If so, I doubt that such a thing exists, at least as a software tool.
Or, are you looking for a graphic-enabled (i.e. framebuffer, but not X)
remote display? If so, then VNC might be what you are looking for. I'm not
talking about the VNC "X Server", but a raw VNC handler.
Finally, if you just want character data back and forth, why not use ssh or
telnet?

"More recently"? The X Window System has always worked seamlessly over
the network (i.e., since before KVM switches were invented).

ssh works for me (perhaps with screen).

What are you trying to accomplish?

I'm installing Gentoo on a laptop, and getting a sore back from all the
leaning over sideways to read the documentation. I could do it much more
easily if I could just use my desktop keyboard and monitor.

I don't think I need that. I need character data going over the line,
preferably including the colours.

OK, I'll look at that.

A good question! I've already used ssh from the prototyp Gentoo system.
Can ssh transmit colour information, like what you get when you do "ls
--color"?
In fact, that's such a good idea, I'm going to go and try it out right
now. Thanks!

Yes, it can. You need to ensure that both ends use the appropriate terminal
definition though. With $TERM set to "xterm" on the target end (where the
programs will run), and running in an xterm window on the source end (where
I'm sitting), my ssh session to my server responds with colour
for "ls --color" commands

I can access my ancient desktop machine using ssh from the prototype
Gentoo box. I can even run full facility Emacs from it. I can't, as
yet, access the laptop from my desktop box. No doubt, some simple
modification (such as creating a non-root user on the laptop) will make
it work. Or do I need to install an ssh-daemon on the laptop?
Anyhow, the ssh idea was so brilliant, I'm wondering why I didn't think
of it myself. ;-)

Yes, of course.

In the last several years many software distributions have chosen
to invoke the X11 server with the "-nolisten" argument, which disables
some of the visible network functionality. This is an extra layer of
"security." I have been inconvenienced by this practice a couple times,
such as when I want to be remote from both the server and the display.
[Three machines: mine, the server, the display:
ssh a.b.c.d "DISPLAY=e.f.g.h:3 /path/to/client"
where screen 3 at ip4 e.f.g.h has the client display and pointer
(mouse), the program is running on ip4 a.b.c.d, and I have stdin+
stdout+stderr but no login account on the machine with the display.
This is quite some fun, particularly when client is a debugger
such as gdb!]

Or "ssh -Y" if forwarding an X11 connection.

I don't know of any off hand that I can recall, just stay away from any
of the Java based crap, and, like you said, try and get one you can
connect to over a normal terminal via SSH.
