== Ubuntu Images at DETER == Our Ubuntu images have full apt support for installing packages. The packages are mirrored locally on our package mirror [wiki:scratch]. === Ubuntu1004-STD === Ubuntu 10.04 LTS. Full package mirror on scratch. ==== Updating custom Ubuntu1004-STD images to fix control network discovery race condition ==== Currently, we do not have an elegant method to automatically update client scripts on custom Ubutnu images. This issue is important enough that you will want to update any Ubuntu images created before March 2, 2012. Two files need to be updated, dhclient-exit-hooks and findcnet. You should be able to copy and paste the commands below to easily update your image running on a testbed node. After that simply take a snapshot to update your image. {{{ sudo curl --output /etc/dhcp3/dhclient-exit-hooks boss.isi.deterlab.net/downloads/client-update/Ubuntu1004-dhclient-exit-hooks sudo curl --output /usr/local/etc/emulab/findcnet boss.isi.deterlab.net/downloads/client-update/Ubuntu1004-findcnet sudo chmod a+rx /etc/dhcp3/dhclient-exit-hooks /usr/local/etc/emulab/findcnet sudo chown root:root /etc/dhcp3/dhclient-exit-hooks /usr/local/etc/emulab/findcnet }}} For example, I have my custom image loaded on pc031. {{{ [jhickey@users ~]$ ssh pc031 Linux centos.jjh-centos.detertest.isi.deterlab.net 2.6.32-38-generic #83-Ubuntu SMP Wed Jan 4 11:13:04 UTC 2012 i686 GNU/Linux Ubuntu 10.04.4 LTS Welcome to Ubuntu! * Documentation: https://help.ubuntu.com/ System information as of Mon Mar 12 16:00:28 PDT 2012 System load: 0.12 Processes: 135 Usage of /: 7.7% of 14.67GB Users logged in: 0 Memory usage: 1% IP address for eth1: 192.168.1.31 Swap usage: 0% Graph this data and manage this system at https://landscape.canonical.com/ Last login: Mon Mar 12 16:00:03 2012 from users.isi.deterlab.net ookskey@centos:~$ sudo curl --output /etc/dhcp3/dhclient-exit-hooks boss.isi.deterlab.net/downloads/client-update/Ubuntu1004-dhclient-exit-h % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 101 2943 101 2943 0 0 1573k 0 --:--:-- --:--:-- --:--:-- 2874k jhickey@centos:~$ sudo curl --output /usr/local/etc/emulab/findcnet boss.isi.deterlab.net/downloads/client-update/Ubuntu1004-findcnet % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 101 2331 101 2331 0 0 1300k 0 --:--:-- --:--:-- --:--:-- 2276k jhickey@centos:~$ sudo chmod a+rx /etc/dhcp3/dhclient-exit-hooks /usr/local/etc/emulab/findcnet jhickey@centos:~$ sudo chown root:root /etc/dhcp3/dhclient-exit-hooks /usr/local/etc/emulab/findcnet jhickey@centos:~$ }}} Now the scripts are updated and I can take a snapshot. === Ubuntu804-STD === Ubuntu 8.04. We will continue to upate this image as long as it is supported by Ubuntu.
