<DIV><FONT face=Arial size=2>Hi Matt thanks for all that. ill try some different
cables and keyboards both KVMs I have are electronic, the 4 port one is a
real expensive one that was ripped out of GCHQ about 4 weeks ago, I managed to
get my hands on it from a salvage guy I know, all that being said I had to build
a PSU for it so maybe its low on power. If that fails I think ill invest some
cash in he korega 4 port and invest some time after in keeping the power on with
my old ones.</FONT></DIV>

KVM</DIV>
<DIV><BR></DIV>Yes, we do... Inexpensive KVM switching is known to be
problematic. Makes me wonder why these things are
sold!!!<BR><BR>Mouse/keyboard outages in this case are caused whenever they
lose power due to switching them between PCs, which will almost invariably
happen when you use conventional mechanical switching.<BR><BR>The solution is
to use an electronic KVM switch, which keeps the attached mouse & keyboard
alive (and keeps the respective ports satisfied) while their data lines are
switched between PCs. The electronic KVM switch derives power from one of the
attached ports, and/or a separate PSU. You can get quite sophisticated with
this stuff and potentially cascade many such devices.<BR><BR>At work we're
happily using a Korega 4:1 KVM switch, cost about £40, between 4 Linux
servers. However I dare say there are plenty of DIY ways to achieve the same
effect, but it depends on how you price your time!<BR><BR>How about a project
to improve a cheap KVM switch - ie. keep both mouse & keyboard powered by
one and/or other attached PCs - so that there's no loss of service? I'll have
a think while I'm slacking out at Glastonbury next week...<BR><PRE class=moz-signature cols="72">Best Regards,

<DIV><FONT face=Arial size=2>Is any one in the LUG using Linux with a KVM,
more to the point can any one suggest why when using a KVM with
Linux<BR>sometimes I switch over and all is fine, a few minutes later
however I switch over again and the keyboard fails to work. seems to be
related to the shift keys because sometimes when you push them a few times
(Bash them more like) it starts to go again, I have tested on different
keyboards as well but the hardware at the moment is as follows.</FONT></DIV>
