I currently have an instance where such an app could be useful. Will have to check it out and see how it does.

Slick looking tool for creating a treemap of folder sizes in Windows. Beats the crap out of my old fashioned manual method of bringing up the properties of each folder in the drive root and working my way down through the largest ones.

Some updated LXC networking, plus Linux network namespaces
Posted July 18, 2014 By Landis VFour very good articles I’ve encountered today regarding networking in Linux containers. This is a space that has blossomed and matured surprisingly quickly, and many of the frustrations I had previously encountered are gradually being solved.
I was initially researching veth’s and bridging a container network to the host network. I have a container inside a VirtualBox VM with a NAT network, and want to bridge the container so it retrieves an address from the VirtualBox NAT network. As I’ve dug into it further, this appears to actually be what’s happening, but I start to run into issues when I attempt to set up a port forward on the VirtualBox NAT to a service running within the LXC container.
A Brief Introduction to Linux Containers with LXC

Introducing Linux Network Namespaces
More interesting to me in the context of VRF lite a la Cisco than in the context of LXC, but definitely something I’ll be coming back to.

Exploring LXC Networking
Gets into LXC testing using Vagrant, which is another tool I have been meaning to learn more about. Perhaps one of the most helpful articles in understanding just what I was encountering.

Disposable Development Boxes: Linux Containers on VirtualBox
This was a second search as I started to look more into the issues getting the forwaring to work right. Egresss from the container seemed to work OK, I could ping Google and such, but I couldn’t seem to bring anything back in easily.

Arch Linux ARM • View topic – Pogo V4 A101 Mobile Hardware Mods?
Posted July 12, 2014 By Landis Vhttp://archlinuxarm.org/forum/viewtopic.php?f=53&t=6040
I picked up a couple of POGO-V4-A1-01’s from eBay for $7.50 apiece shipped and thought I might try using them for sensor devices and/or generic simple alerting systems. The hardware mod listed in this forum will be very helpful in adding another interface to the device, as my understanding is that it will only boot from the USB or the SATA port, and the device will be much more useful if the USB port is available for peripherals.
Clean up images with free tools

Resolve IP Fragmentation, MTU, MSS, and PMTUD Issues with GRE and IPSEC – Cisco
Posted June 26, 2014 By Landis Vhttp://www.cisco.com/c/en/us/support/docs/ip/generic-routing-encapsulation-gre/25885-pmtud-ipfrag.html
It seems somehow I’ve never managed to run across this particular article describing path MTU discovery (PMTUD) in conjunction with IPSec and GRE tunnels. Scenario 10 is a particularly good and detailed description of how it can go, even taking into account situations common to PPPoE DSL connections which have an MTU of 1492 (the 1400-byte MTU link in the scenario would have the same effect).
Ran across this one while looking for any documentation/information about AT&T ignoring the DF/”don’t fragment” bit and proceeding to fragment at will, breaking path MTU discovery. I’d love to find a way to get them to stop doing that on my connections, and just let the protocol work as it is supposed to.
