apt-dater provides a ncurses frontend to manage package updats on a large number of remote hosts using SSH. Beginning with version 0.5.5 apt-dater supports Debian based managed hosts and now also rug (openSUSE...) and yum (e.g. CentOS...) based systems.
Apt-dater works great.
This is amazing program which save us a lot of work when updating larger number of servers.
