Connecting to Apple Remote Desktop from Ubuntu
Monday, March 3rd, 2008Apple uses the tightvnc protocol for remote desktop. So install tightvnc:
sudo apt-get install xtightvncviewer
Then update your default programs to use it instead of what’s included in Ubuntu Desktop:
sudo update-alternatives --set vncviewer /usr/bin/xtightvncviewer
That’s it. In ubuntu’s RDP client, select the vnc protocol when connecting to a mac.
Yes, we’re moving from SVN to Git too

Ssh tunnel to remote MySQL
Thursday, January 10th, 2008You’ve got port 3306 (MySQL) firewalled off and you want to use a MySQL GUI every once in a while (or maybe a bunch).
This is a snap with ssh.
On your local Linux/BSD/Mac/Unix machine (works in cygwin too) edit your .ssh/config file and add:
Host somemysqlserver Hostname server.mydomain.com #your mySQL server FQDN or IP User bob #replace with your valid ssh server username LocalForward *:13306 localhost:3306
Now do:
ssh -f -N somemysqlserver
You can now connect to your localhost port 13306 and it will forward to your MySQL server’s port 3306.
Plus, it’s free and probably already installed on your systems.

Ubuntu 7.10 Laptop Upgrade
Thursday, October 18th, 2007I just upgraded my IBM T41 to Ubuntu 7.10 by doing:
update-manager -c
from the command line. This forces a dist-upgrade check and runs through a pretty slick upgrader. 20 mins and 1 reboot later and she’s back and running without any issues at all.
Very sweet. I love it when things just work.
