Apple has released OS X Server 2.1.1, which has been updated with the capability of managing DHCP from within the Server app as well as adding support for iOS 6 devices to the Profile Manager. The release also enables management of the blacklist settings for the Mail service, prevents spurious “Host name changed” alert messages after restarting, addresses an issue where AirPort base stations couldn’t be managed after updating from previous versions of OS X Server (as well as some other migration issues), and allows for setting a default NetBoot image in the Server app. ($19.99 new, free update, 136 MB, release notes)
Viewing Wi-Fi Details in Snow Leopard
In Snow Leopard, hold down the Option key before clicking the AirPort menu. Doing so reveals additional technical details including which standards, speeds, and frequencies you're using to connect, as well as what's in use by other networks. With the Option key held down and with a network already joined, the AirPort menu reveals seven pieces of information: the PHY Mode, the MAC (Media Access Control) address, the channel and band in use, the security method that's in use, the RSSI (Received Signal Strength Indication) measurement, the transmit rate, and the MCS Index. In Leopard, some, but not all, of these details are revealed by Option-clicking the AirPort menu.
