Re: help

Hi Andy,

nice to hear that you got the password-less ssh-login working on your nod=
es.
You can check if it is working with openMosixview by e.g.=20
increasing/decreasing
the nodes speed in the main window. This will result in a remote-mosctl=20
command
via ssh on the node you are moving the slider.
On the node you can check if the command was executed correctly by runnin=
g
the mosctl util locally and compare the speed to what openMosixview displ=
ays
(-> should be the same)
You can also check /var/log/messages on the remote node for any ssh-login=
s
while executing a openMosix command via openMosixview.

For getting the openMosixprocs working you need to have the openMosixproc=
s
installed on each of your cluster-nodes.
Also you need to set "xhost +" to allow the remote nodes to open X-window=
s
application (-> openMosixprocs) on the main/local display (the=20
workstations X on
the system you are running openMosixview on). Be aware to do this only=20
in trusted-networks
because setting "xhost +" is unsecure. It will allow all nodes to=20
display X-apps
on your display. You can also set "xhost +[cluster-nodes-hostname]" for=20
each of your
cluster-nodes to get a better security.

btw: for getting the openMosixprocs working you need to make sure that yo=
ur
default ssh-client setup supports X-forwarding. You can enable/disable th=
is
in /etc/ssh/ssh_config on your system you are running openMosixview on.
-> ForwardX11 yes
You can check if this option is enabled by login in to one of your=20
remote nodes
by "ssh [cluster-nodes-hostname]" and running openMosixprocs from the=20
console.
The openMosixprocs application window should be opened on your local=20
systems X-windows.
If not please try the same but login by "ssh -X [cluster-node-hostname]".
If the first did not work but the second you need to adjust your ssh_conf=
ig.

If you still have problems with that please try to run openMosixview by=20
the strace command.
e.g. "strace openmosixview"
Then execute some openMosix-commands or move the sliders. The output of=20
the strace would
be intresting and usefull to help you better.

many thanks and stay tuned,

Matt
