rsh typically uses ports in the 513-1023 range. With a 640 node cluster we are running out of ports. This leads to messages such as: "rcmd: socket: All ports in use" Are there any standard solutions to this other than 'use ssh'? We already have net.ipv4.tcp_tw_recycle = 1 in /etc/sysctl.conf Cheers, Bruce
