At office I'm trying to solve a heavy statistical problem by means of
parallel computation with R and pvm.
The problem is with setting up the
cluster of computers which - to begin with - is made of two pentium 4
with freebsd 5.4 (host uffbsd) and 6.0 (host NbBSD).
They see each
other. From NbBSD:
# ping uffbsd
PING uffbsd.grtn.prv
(10.155.194.115): 56 data bytes
64 bytes from 10.155.194.115:
icmp_seq=0 ttl=64 time=0.221 ms
64 bytes from 10.155.194.115:
icmp_seq=1 ttl=64 time=0.193 ms
But trying to setup the virtual
machine

Diagnosing Failed Hosts...
uffbsd...
Verifying Local Path to "rsh"...
Rsh found in /usr/bin/rsh - O.K.
Testing Rsh/Rhosts Access to Host
"uffbsd"...
Rsh/Rhosts Access FAILED - "uffbsd.myd.prv: Connection
refused"
Make sure host uffbsd is up and connected to
a network and
check its DNS / IP address.
Also verify that NbBSD.myd.prv is allowed
rsh access on uffbsd
Add this line to the $HOME/.rhosts on uffbsd:
NbBSD.myd.prv victor
...........................................
Of
course, in /home/victor/.rhost on uffbsd there's the required line.
The
same reciprocal situation happens from host uffbsd.
Perhaps I'm
missing something.
Could you please help me?
