Preserve Cisco router DHCP leases across a reboot by configuring a DHCP database agent, verifying successful writes, and choosing a storage target that fits the platform.

On a whim today I decided to give Sumo Paint a try. I'm really surprised with the quality of this product. I never would have guessed that a free, browser-based image editing tool would be so responsive and easy to use.

Last week I mentioned that I was working on a Quality of Service (QoS) project. For those who are curious about QoS and how to get it working, here are the resources I found most useful. These resources are mostly Cisco specific, but the principles should be applicable in many …
