After a month or so, unstable or testing archives may distribute the packages on their CDs. Thus, although non-free works are not a part of Debian, we support their use and provide infrastructure for non-free packages (such as our bug tracking system and mailing Firewall (UFW) firewalld V:11, I:16 2613 firewalld is a dynamically managed firewall program with support for network zones firewall-config V:0, I:3 1163 graphical user interface for firewalld shorewall-init
