To enable rsh, create a /.rhosts file on each target system. Then add a line to the file specifying the full domain name of the source system. For example, add the line:
sysname.domainname.com root
Change permissions on the /.rhosts
file to 600 by typing the following command:
# chmod 600 /.rhosts
After you complete an installation procedure, delete the .rhosts file from each target system to ensure security:
# rm -f /.rhosts
