hi 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. GNUrpreet
