[plug] KVM switches - serverlink

[James Elliott]

I checked with D-Link (Australia) support and the D-Link KVM switch is O/S
and Monitor/mouse/keyboard independent - not the source of my Linux/WinXP
problems

Tests of my own show that the switch had nothing to do with the problems I
reported the other day

G'day...

I use a serverlink 4 port KVM switch and have had mouse wierdness but it
has always been fixed by using PS/2 instead of the IMPS/2 mouse setting
on Linux.

If any of you are investigating purchasing KVM switches and wanting to
support Australian industry, I recommed the serverlink brand as they are
very reasonably priced and Australian made! www.serverlink.com.au

Also their cables are a good price and we have purchased them for use
with another brand of KVM switch that we have (brand name eludes me at
the moment, but some small US vendor).

I have successfully used the serverlink KVM with a 15M cable from
keyboard/monitor/mouse to the switch and 2m cables to the computers and
it has performed beautifully!

Holy cow, this sounds like an advert for the things. It isn't intended
that way - just me putting in a vote of confidence for a local producer!

deconfigs?


I have seen KVM switches that have a CTRL option which allows you to
re-sync
the mouse and keyboards.
I have also seen similar problems when the mouse cable, to the KVM
switch,
was too long.  I don't know the limit, but the KVM switch manual should
have
cable limitations.
I am currently using a KVM between a RedHat 7.3 and Windows 2000 Pro
systems, with no problems.  My cables are 2 meter cables.

Dear PLUG members,

The following from a colleague.  I have done google'ing, altavista'ing
and
so forth.  Closest I come is the suggestion that "some cheap kvm
switches
give this problem.  I have no idea what breed of kvm switch my colleague
is
using but any thoughts would be valued!

"I have 2 PC's on my desk connected with 1 keyboard/mouse/monitor via a
2-port switch box (press the button to switch between boxes). 1 Box in
WinXP, which works fine, and the other is Redhat 7.3. If I use the WinXP
box
for an extended period (more than an hour or so), when I switch back to
the
Redhat box, the mouse operation is all over the place, and I cannot use
KDE.
If I can manage to quit KDE, then re-start a fresh KDE session, then the
mouse is OK. I have seen similar problems before when I have the wrong
emulation set for the mouse - but this is odd as it initially works
fine. Is
there a timeout setting that checks mouse connectivity that might need
adjusting here? I am guessing that after a set time, Redhat assumes the
mouse is missing and drops the emulation function. When I then switch
back
to the box, it sees hardware it knows nothing of in effect, and is
unable to
'plug & play'. (The mouse is an MS IR Intellimouse)"

I've seen references to timeouts and mice but only in the context of
3-button emulation.   I guess one option is to forget the kvm switch and

just run something like VNC (server) on the XP and use the RH box
natively
and as the VNC client for the XP.
TIA,
Denis
