I found one way to run PVM.
On the Master, edit the inetd.conf and uncomment the rshd and
rlogin parts.
Issue
a 'killall -HUP inetd.conf' to re-read the file.
Prepare a suitable /etc/exports file to allow the nodes to have
nfs access.
You
will need to stop and restart nfs to re-read the new exports
file.
Prepare a suitable .rhosts file in $HOME to rsh without a
password.
The following commands should then be run:
bpsh <n> hostname <hostname> for each of your nodes. I do this
for
friendliness though it is not necessary. You will need a suitable
/etc/hosts
file if
you use this method.
Mount the following:
bpsh -a mount -t nfs -n 192.168.1.1:/home /home (if not mounted
already)
bpsh -a mount -t nfs -n 192.168.1.1:/etc /etc
bpsh -a mount -t nfs -n 192.168.1.1:/bin /bin
bpsh -a mount -t nfs -n 192.168.1.1:/usr /usr
bpsh -a mount -t nfs -n 192.168.1.1:/lib /lib
The -n flag stops any problems with mtab.
Run bpsh -a /usr/sbin/inetd
Start a pvm session on the master and then add your nodes by
hostname. Once
done,
check pvm>conf to see that all is in order.
This is very much the long way round and should really be
scripted!
I hope that this helps,
