Ubuntu Images at DETER

Our Ubuntu images have full apt support for installing packages. The packages are mirrored locally on our package mirror scratch.

Ubuntu1004-STD

Ubuntu 10.04. Reverse path filtering disabled in sysctl.conf because the feature can break connectivity. Updated to kernel 2.6.32-31 with IPOD; gawk favored over mawk; and with better compatibility with nve on bvx2200.

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.

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

Ubuntu804-STD

Ubuntu 8.04. We will continue to upate this image as long as it is supported by Ubuntu.
