Ubuntu 9.10

I took the plunge and upgraded from Ubuntu 9.04 to Ubuntu 9.10 on my work laptop. The process was incredibly smooth, and there’s not much to it apart from that.  I’m crossing my fingers and hoping the dbus problems with 3G dongle PPP connections have gone away.

I am waiting for some free time at the weekend and a pair of 1Tb hard drives before I take the plunge and install the 64-bit version on my desktop at home.

Cisco IOS 15.0(1)M

I am never one to fear something new – except perhaps a new release of a JVM.

Some weeks ago, I decided it would be a good idea to upgrade one of my home routers to IOS 15.0(1)M – seeing as I paid enough for a maintenance contract, I’m entitled.  Ever since that day, I’ve been unable to ssh to the router with an access-class applied to the VTY lines.  Every time, it refuses my connection, but allows it without an access-class.

This morning, I stumbled upon the answer – put ‘vrf-also’ at the end of the access-class line: access-class 99 in vrf-also. This only matters if you’re running VRF Lite, as I am, because I have a separate firewall and ‘clean’ and ‘dirty’ VRFs.

Never fear something that’s new – expect breakage, and expect to learn.

On The Buses

TfL’s Countdown system for London Buses was a leap forward several years ago. I can now walk up to a bus stop and tell – with reasonable accuracy – how long before my bus arrives.

There is one problem with this – I have to be at the bus stop!

When National Rail introduced Live Departure Boards several years ago, it was a giant leap forward for rail travellers. TfL brought in Live Departure Boards for the Underground some years later, although this is less useful.

Wouldn’t it be absolutely fantastic to have a map of a bus route with the positions of the buses on it? Colour the map in with a deeper shade where the route is more congested, and let people have a visual representation of how long it’s likely to take for their bus to arrive. Before you leave home, have a look to see where the delays are on your route in to work, and re-plan your journey if it’s going to take too long.
