Experimental Docker Libnetwork DHCP Driver

The DHCP driver is intended for users to be able to integrate Docker IP address management with their existing IPAM strategies that use DHCP for dynamic address assignment. DHCP enables users to allocate addresses in an organized fashion that will prevent overlapping IP address assignment by associating a unique MAC address from the container eth0 Ethernet interface to an IP address as determined by the DHCP pools defined in the DHCP configuration.

This driver only provides the DHCP client functionality. It does not include a DHCP server. The default driver offers single-host IPAM or for distributed multi-host orchestrated IPAM see the libnetwork overlay driver.

Uninstall nodejs from OSX Yosemite
# first:
lsbom -f -l -s -pf /var/db/receipts/org.nodejs.pkg.bom | while read f; do sudo rm /usr/local/${f}; done
sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*
# To recap, the best way (I've found) to completely uninstall node + npm is to do the following:
# go to /usr/local/lib and delete any node and node_modules
cd /usr/local/lib
sudo rm -rf node*
// kills long running ops in MongoDB (taking seconds as an arg to define "long")
// attempts to be a bit safer than killing all by excluding replication related operations
// and only targeting queries as opposed to commands etc.
killLongRunningOps = function(maxSecsRunning) {
currOp = db.currentOp();
for (oper in currOp.inprog) {
op = currOp.inprog[oper-0];
if (op.secs_running > maxSecsRunning && op.op == "query" && !op.ns.startsWith("local")) {
print("Killing opId: " + op.opid
