Yay Yay RSA!

The key point I took away from RSA's communications today is that all implications are that it's likely their token seed database was taken and that token codes are predictable, and may be able to be matched to customers.

They didn't say this, clearly, but every action they suggest to mitigate risk points to the fact. The mitigation steps they give are:

Help me kill this window

I have a bash script on my work Mac which creates an ssh tunnel to my home machine, then runs the Mac ScreenSharing.app VNC client so I can VNC home without opening VNC externally. All this works great with key based auth and stuff for the ssh session, so I just get a login prompt for the VNC session and I'm on my way.

At the end, I try to have it clean up after itself, I've tried using waits and then killing the PIDs associated with things like the tunnel, so when Screen Sharing closes, it tears down the SSH tunnel.

A new job for the little Asus

I think I've finally found the perfect job for the little Asus EEE, since it's just too weak to show good video. It has the following tasks:

Asus EEE Is Fired

I've spent some time with the Asus EEE 1006. It was one of those almost there, maybe if I tweak... situations, and I've given up wasting time tweaking.

Sphere of Inconvenience

So... As I was putting together my most recent post regarding IPv6 I got to thinking about how many computers I use every day. It started as I counted up how many things in my house use IP addresses. From here forward I will refer to anything that uses an IP address as a computer for simplicity (yes, that means that in this context my iPhone is a computer, as is my Tivo, and my Linksys wireless access point).

IPv6

There has been a lot of chatter on the CentOS list lately regarding the ups and downs of IPv6. It has not quite boiled down to a flame war yet, but now is a good time to start distilling down what everybody has had to say.

To start, what IS IPv6? Simply put, it is a newer implementation of IP addressing that allows for many more hosts, as we have been running out of IPv4 addresses and will come to the end shortly. In fact, it allows for more than 2^95 or 5x10^28 addresses per person alive on planet earth today. "Overkill!!!" you might exclaim. In the 70s, when IPv4 was designed, and there were less than 1000 hosts internetworked, you would have said the same thing about the mere 4 billion addresses allowed in that system. In an age where having your toaster internet accessible is not unheard of, you'd be surprised at how many you might use.

A week with the Asus EB1006

Just bought an Asus EB-1006, and wanted to post how it works rather than send one email to half a dozen folks. I got it working pretty well with XP for HD movies and MAME, here's what I did:

Dear Internet Advertisers

[music | Nick Cave and the Bad Seeds - All Tomorrows Parties]

This week both Ars Technica and Fark, both of whom get decent traffic, have basically begged users not to use ad blockers. I think people would be less likely to use ad block if your ads didn't kill our browsers, below are some examples.

Find LDAP groups with obsolete users

OpenLDAP has a nice "feature" that allows for group members to continue to exist, even if the user does not exist any more. Really handy! Problem is, if you, say, have a user in the "Domain Admins" group, and you delete that account, and then some normal user comes along with the same username, they will end up with unexpected elevated privileges.

So I created a script that I run weekly that finds group members that no longer exist, and sends me a report. It also tells me which groups are empty.

This relies on my toolbox... Find it here.
