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 pvm> add NbBSD add NbBSD 0 successful HOST DTID NbBSD Duplicate host pvm> conf conf 1 host, 1 data format HOST DTID ARCH SPEED DSIG NbBSD.myd.prv 40000 FREEBSD 1000 0x00408841 pvm> add uffbsd add uffbsd 0 successful HOST DTID uffbsd Can't start pvmd Auto- 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? Vittorio
