Hi, attached are two scripts: "drain-RB.sh" and "allow-RB.sh". When "drain-RB.sh" is run on an RB, new job submissions to that RB will immediately fail, while the output of earlier jobs can still be retrieved. It uses "iptables" to block outside access to the "logd" on port 9002. To make the RB fully usable again run "allow-RB.sh".
