Network MacGyver

I make the internet work. In turn, the internet provides me with boundless entertainment. This is a chronicle of my journey through the intertubes. Now, get me a spool of cat5e, some chewing gum, and a paperclip.

Thoughts on the English Bay oil spill

I wrote about this in Facebook, but have to post it here too.

Reading about the oil spill in English Bay makes me sick to my stomach. Because of Stephen Harper’s cut backs, and the closing of the Kitsilano Coast Guard station, the response to the spill has been disorganized and slow.

It took 6 hours for booms to go out around the spill to contain it. The former Kitsilano Coast Guard base commander Fred Moxey has said that it would have taken his team six *minutes* to respond if the base was still open.

Just heartbreaking seeing pictures of birds and beaches covered in toxic bunker fuel.

Remap Dashboard Key to Launchpad in OS X

I have a Retina MacBook Pro, but a slightly older Apple USB Keyboard. It bugged me that when I pressed the "F4" key on my laptop's keyboard, it would bring up Launchpad, but on my USB keyboard, it brought up Dashboard. After some snooping around, I figured out how to re-map this key to open Launchpad, rather than the Dashboard.

defaults write com.apple.symbolichotkeys AppleSymbolicHotKeys -dict-add 160 "{enabled = 1; value = { parameters = (65535, 130, 0); type = 'standard'; }; }"

Configuring Cisco IOS router for OpenDNS dynamic updating

Do you run a branch office (or a home lab network) with a Cisco IOS-based router? Do you use OpenDNS? I was running into an issue where every time my DHCP address changed on the external internet connection, I'd have to go into the OpenDNS panel, and reset my IP address. I discovered however, that OpenDNS supports the DynDNS HTTP method for dynamically updating my IP address in their system.

version 15.4 ! ip ddns update method opendns HTTP add http://USERNAME:[email protected]/nic/update?hostname=<h>&myip=<a> ! interface FastEthernet4 description External Network ip ddns update opendns ip dens update hostname NETWORK-LABEL-IN-OPENDNS-PORTAL ip address dhcp ip nat outside !

TCAM Allocation Adjustment Procedures for CAT 6500 and 7600

With the consistent growth in the routing table (currently at ~504261 routes), many older routers are struggling to deal with the size of the IPv4 routing table. This article documents how to adjust the TCAM allocations in the 6500 and 7600 platforms from Cisco. While this procedure doesn't increase the size of the FIB TCAM, what it does do is allocate more of it to IPv4, and less to IPv6. As such, it should be only undertaken as a temporary measure -- long term these routers need to be upgraded. Of particular significance is the Sup720 card that has an extremely wide deployment. The Sup-2T card supports dynamic allocation of it's 1 million FIB TCAM entry spaces between IPv4 and IPv6. This is the preferred upgrade path, as the Sup-2T card can also be used in the successor chassis to the 6500, the Catalyst 6800.

This is totally the nineties. I feel like I should be cross-posting this to my LiveJournal.

I am of course excited about this for the kids. Yes. The kids.

Network engineers love and loathe vendors. Vendors provide us with the shiny technical gear and fabulous nerd knobs that feed our need to tinker with new technologies. They also drive us to the brink of madness with their quirks, and for some of us, that’s a pretty short trip.

The Open-Office Trap

Interesting article out of the New Yorker saying that open office spaces might be more damaging than productive.
