Ensure that the .rhosts resides in the home directory, and also that its permissions are set to -rw------- i.e. 600 for the user _only_. % chmod 600 .rhosts % ls -l .rhosts -rw------- 1 tstuser tstuser 14 Mar 25 11:36 .rhosts % Otherwise the rsh daemon will ignore your .rhosts file. In addition to run 5 simultaneous processes on your machine, ensure that five lines with hermes appear in the file e.g. %cat machines.LINUX hermes hermes hermes hermes hermes % Hope that helps. -DAL- -- dylanal@earthlink-NOSPAM-DAMMIT-.net to reply, take -NOSPAM-DAMMIT- out of address
