The version of libnss-ldapd included in Ubuntu 8.04 has many bugs that have been fixed. One rather annoying bug is a problem parsing map configuration. Please find the deb I built of 0.6.4 on 32bit Ubuntu 8.04.1 here.
I spent quite a long time googling for a way of re-creating symmetric cone nat in house without buying Cisco hardware. Hopefully someone else will find this useful. This was done on Ubuntu 8.04 beta.
eth1 = public ip
eth0 = lan ip
echo “1″ > /proc/sys/net/ipv4/ip_forward
/sbin/iptables –flush
/sbin/iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE [...]
Rails and J2EE Deployment
Hongli Lai asks why some think Rails deployment is difficult. First, a disclaimer. I am not a Ruby on Rails expert. I have only used Rails for one small production project. I found both Ruby and Rails quite easy to pick up coming from a J2EE background. What can be done with such [...]

Draft 1 OAuth 1.0 spec was announced yesterday. By my count, it requires no less than 6 HTTP request/response round trips assuming the user is already logged in to the service provider.
If the user is NOT logged into the service provider and has to log in before approving or denying the consumer’s request, [...]
Looking for a solution to increasingly complicated OpenOffice.org Calc spreadsheets for maintaining our business and personal finances, I took another look at GNUCash and was pleasantly surprised by its improvement since the 1.x days.
You should be able to install my deb built by following these directions using the below instructions on an update [...]
Why does a Landscape-managed deployment of Ubuntu cost US$250 per seat per year? For my 7-seat deployment in our new China-based subsidiary, that would cost us US$1,750/year. Compare to the Microsoft Partner Program’s Actionpack Subscription at HK$2,792 (~US$350) per year. The Actionpack Subscription even provides 10 seats worth of internal-use software. That means [...]
Ubuntu Edgy Update Mania
Isak Savo writes about the daily edgy updates that have been appearing the past two weeks. You know there’s a problem with pushing out updates too often when the update icon on Edgy, supposedly the stable version, appears more frequently than the update icon for Feisty, the current development branch. This is starting [...]
Updated Feisty today and after restarting (new kernel) and logging in, I was prompted with a balloon indicating that Ubuntu may be using restricted drivers. Clicking on the new tray icon in the notification area popped up the following window:
I like how it informs users in rather polite language that proprietary drivers are almost [...]
Packages for Beryl 0.2.0 were released. After updating to them and restarting Beryl, my entire desktop was sluggish and a quick look at top indicated that Beryl was consuming most of the CPU. Deleting my old Beryl settings and restarting Beryl seemed to solve the problem:
