Can I load my own software (RPMs/Tarballs) on my nodes?
Yes! If have an RPM or Tarball (or more than one) that is appropriate for loading on the OS you have selected, you can arrange to have them loaded automatically when your experiment is configured. The Emulab NS extension tb-set-node-rpms is used in the NS file to specify a list of RPMS to install. The tb-set-node-tarfiles is used to specify a list of Tar files to install (as well as the directories in which the tar should be unpacked). You may specify a different list for each node in the experiment. When the node first boots after the experiment is configured, each of the RPMs/Tarballs will be installed (but only those which have not already been installed). Please see the Extensions page for a summary of all Emulab NS extensions, and the DETERlab Tutorial for an example. • Can I schedule programs to run automatically when a node boots? Yes!
