>&#13;First of all , are you using the same kernel version on each machine ?
The 'same-kernel' refers to the version. You can build different kernel
images of the same source version to meet the hardware/software needs of a
given node.
However you wil need toe make sure that when you install openMosix
on your cluster, all your machines should have the openmosix-x.x.x-y
kernel installed, in contrast to having one machine running
openmosix-x.x.z-x, another running openmosix-x.x.x-y, another running
openmosix x.x.x-z, and so on and so forth
&#13;</P
><P
>&#13;When you run mosmon, press t to see the total of machines running. Does
it warn you that mosix is not running?</P
><P
>&#13;If yes, then make sure your machine's ip is included in /etc/mosix.map
(don't use 127.0.0.1 - if your machine's ip is such, then you probably
have problems with your dhcp server/nameserver). If it does not tell you
that mosix is not running, see what machines show up. Do you see only your
machine?</P
><P
>&#13;If yes, then your machine is most likely running a firewall and is not
letting openmosix through.</P
><P
>&#13;If not, then the problem is most likely with the machine that doesn't show
up.
Also: Do you have two nic cards on a node? then you have to edit the
/etc/hosts file to have a line that has the following format

You
might also
need to set up a routing table, which is a whole different subject. </P
><P
>Maybe you used different kernel-parameters on each machine? Especially if
you use the 'Support clusters with a complex network topology' option you
should take care that you use the same value for the also appearing option
'Maximum network-topology complexity support' on each machine.
