Before using the Task Manager, the following actions must be done:
1. Modify the .rhosts file in the home directory by introducing all the machines which can be used
by the Task Manager. i.e.: if the machines machine1 and machine2 will be used by the user’s
tasks, the .rhosts file must be modified as follows:
line1: machine1 <login1>
line2: machine2 <login2>
where machine1 and machine2 are the host names.
login1 and login2 are optional. They must be set if the login on remote host is different from
the login on the local host.
The .rhosts file needs to be ended by a blank line.
The .rhosts file permission must be set to ’rw’ (chmod 600 ~/.rhosts).
2. Test the rsh command on the desired machine: an external check that the .rhosts file is set correctly
is to enter the following command line:
% rsh remote_host ls <Enter>
where remote_host is the name of the machine to connect to. If the login on the remote host is not
the same, ensure that the .rhosts file contains the line:
and in this case the command line is:
% rsh remote_host -l local_login ls
If the .rhosts is set up correctly, a listing of the files is shown on the remote host.
