i had a small problem . i m actually using PVM in it and pvm inturn uses rsh for the communication between different nodes of a cluster.

now the problem is that i am being able to rsh between the nodes using commands like

[tony@micks tony]$ rsh tonylin

[tony@tonylin tony]$ ls ***here micks n tonylin are the host names

and tony is the user name****

this kind of a thing works fine, BUT there is another option in rsh such that we send only one command and it gets executed remotely, but i get an error like

[tony@micks tony]$ rsh tonylin ls

rcmd : socket : Permission Denied

[tony@micks tony]$

now i even checked /var/log/messages on both the machines (micks and tonylin) but found no entry!

pvm uses similar things thus i m not even being able to add a host on the virtual machine and it also gives the same error message.

plz help me on this.
