ok, so I have it.

I am sorry, I have /proc/hpc

So, now openmosix start without problems.
But, something bad is happening.
In the master node there is two card network, eth0 (192.168.1.250) and 
eth1 (62.xxx.xxx.211).
My openmosix.map (done by hand) is:
1 192.168.1.250 1
2 192.168.1.1     1

Here you can see what happen with setpe:

master # setpe -w -f /etc/openmosix.map
setpe: the supplied table is well-formatted,
but my IP address (62.xxx.xxx.211) is not there!
master #

Here you can see what happen after run omdiscd:

master # showmap
My Node-Id: 0xc5d3

Base Node-Id Address          Count
------------ ---------------- -----
0xc5d3       62.xxx.xxx.211   1
master #

How I have to configure the master openmosix.map??
