6 Setting Up the Network and
Maintaining Security
This chapter describes the main aspects of setting up your
network for use with Apple Remote Desktop system
administration, as well as best-practice tips for your network.
Additionally, it contains information about Apple Remote
Desktop security features, and detailed instructions for
enabling them. You can learn about:

Setting Up the Network
Your network configuration determines Apple Remote Desktop’s performance and
usability. AirPort and AirPort Extreme networks offer slower performance than almost
any Ethernet network. Therefore, file copying, client monitoring, and reporting are
slower over AirPort and AirPort Extreme connections. Network routers and firewalls also
shape, direct, or block network traffic; these things can have an effect on Apple Remote
Desktop’s reliability and efficiency. Here are a few guidelines to keep in mind when
setting up Apple Remote Desktop on your network:
 The more AirPort clients connected to a base station, the lower the bandwidth for
each computer. AirPort Base Stations are not considered “switched networks.”
 Local Hostname (name using Apple’s Bonjour technology, that looks like: name.local)
browsing does not extend beyond the local subnet. Local Hostnames do not resolve
across routers like domain names do.
 Networks with switches have fewer collisions and packet errors than networks with
hubs. This means greater reliability and speed. Consider using switches instead of
hubs.
