Debian能和既有的环境整合无碍，并和其他操作系统共存。这近乎完美的兼容来自市场的压力：市场要求软件发布者需要遵从一定的标准。接受这些标准让管理员能灵活替换各种程序，客户端或服务端，免费与否，都不是问题。
3.1.2. Integration with macOS machines
macOS machines provide, and are able to use, network services such as file servers and printer sharing. These services are published on the local network, which allows other machines to discover them and make use of them without any manual configuration, using the Bonjour implementation of the Zeroconf protocol suite. Debian includes another implementation, called Avahi, which provides the same functionality.
In the other direction, the Netatalk daemon can be used to provide file servers to macOS machines on the network. It implements the AFP protocol (Apple Filing Protocol, now AppleShare) as well as the required notifications so that the servers can be automatically discovered by the macOS clients.
OS X 之前的系统使用称为 AppleTalk 的协议。为了兼容使用此等协议的环境，Netatalk 也能提供 AppleTalk 协议 (实际上，是重实现该协议)。确保文件服务器、打印队列以及时间服务器 (时钟同步)的运作。它的路由器被设计允许与 AppleTalk 网络互联。
3.1.3. 与其他 Linux/Unix 设备集成
Finally, NFS (Network File System) and NIS (Network Information Service), both included, guarantee interaction with Unix systems. NFS ensures file server functionality, while NIS creates user directories. The BSD printing layer, used by most Unix systems, also allows sharing of print queues.
