Avocen KVM over IP does not work


We attached our RedHat LINUX boxes to our Avocent KVM over IP, but none of the 3 boxes worked. They have the latest versons of RedHat on them. I am very new to LINUX and need help. Any ideas? The video works but the mouse and keyboard will not.

Here is my xorg.conf file. What do I need to change/add?

#more xorg.conf

# XFree86 4 configuration created by pyxf86config

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
RgbPath "/usr/X11R6/lib/X11/rgb"
FontPath "unix/:7100"
EndSection

Section "Module"
Load "dbe"
Load "extmod"
Load "fbdevhw"
Load "glx"
Load "record"

Section "InputDevice"

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
#

What type of cable connection is being used for the keyboard and mouse from the KVM? USB, PS/2

The KVM is connected via a USB cable, USB2.

I would contact Avocent for there input. I always use PS/2 mouse and keyboard cables on my cybex KVM now known as Avocent. I would buy one of those ps/2 cables and give it a try.

The Dell boxes we're having problems with don't have PS/2 ports, only USB.

Keep in mind that connecting a USB keyboard and mouse locally on the box works fine. It's just a problem with the KVM USB module.

Here is another idea. Plug in a keyboard and mouse and the KVM and see if all three can control the machine.

May require edit the xorg.conf. I would leave it alone first but this might be the mouse section might require a second one. Keyboard should not need one. I just base that on my notebook. I can plug in my wireless keyboard and continue typing from. I just did the in the middle of this post to make sure. The wireless mouse took off fine as well. I plugged in a second usb mouse and both usb mice plus touchpad all still work. So I don't think a edit of the xorg.conf is required. What you have is the same as mine for mouse and keyboard.

Check out this post as a reference to what I am thinking of.
http://forums.fedoraforum.org/archiv...hp/t-1939.html

Had another idea. There seems a usbmouse.c and usbkbd.c under the 2.6 kernel source. I believe you would have to manually compile them yourself. They are located in the kernel source at /kernel/drivers/usb/input. But if you can get them compiled for your current kernel then I would try loading them as this as root. Reboot with new kernel and use with the keyboard and mouse directly connected. Run the following commands as root to see if anything wierd happens.
modprobe usbmouse
modprobe usbkbd

If system remains responsive then add those lines to your /etc/rc.local file. Now reconnect to KVM and see if that works.
