Basic Networking (Connect to the Internet)
Mac OS X, like Windows, supports common, standards-based network protocols such as TCP/IP and Bonjour/zeroConf. By default, Mac OS X is configured to use DHCP (Dynamic Host Configuration Protocol), which means the Mac requests automatic address assignment from the attached network. This is the required configuration for using Lehigh's network.

Wireless
Apple's AirPort wireless hardware is standards-based 802.11b/g/n. Lehigh currently provides only secured wireless access over 802.11b/g and incorporating the 802.1x authentication standard (802.11 and 802.1x are two distinct technologies.) Detailed instructions on configuring 802.1x in Mac OS X Leopard are provided in the Wireless link at left. Configuration can also be accomplished automagically through the Lehigh Leopard Wireless Setup utility available here. (174KB disk image.) Additional information is available on the Lehigh Wireless web page.

Printing
Mac OS X can be configured to print to network printers with relative ease, using the Add button in the Print & Fax Preference Pane. Most modern network printers are configured to be browseable, so those located on the same local network (usually within the same building) are visible in the Default printers list via Bonjour. Remote network printers can be added by choosing IP Printer and either IPP, LPD or Socket as appropriate, and typing the full hostname of the printer. [This process has been somewhat automated for registered network printers at Lehigh through the Lehigh Print Select web page.]

Access to LAN drives (H: and I:)
The Lehigh Mac Connector is an application for Mac OS X that automates connecting to your LAN storage space (commonly known as "your H: drive" and "departmental I: drive" because access is provided on Windows PCs using those drive letters mappings.)
Specifics of the connection methods are are expressed in the following matrix:

	Mac OS version	H:	I:
Students	Leopard 10.5.x	Lehigh Mac Connector available here (312K .zip file) (uses the CIFS protocol)	N/A
Students	Tiger 10.4.3+	Lehigh Mac Connector available here (312K .zip file) (uses the SMB protocol)	N/A

Faculty/ Staff	Leopard 10.5.x	Lehigh Mac Connector available for download here (312KB zip file) (uses the CIFS protocol)
Faculty/ Staff	Tiger 10.4.3+	Lehigh Mac Connector available for download here (312KB zip file); (uses the SMB protocol, works on department networks only!)

Installation and usage instructions are provided on the Lehigh Mac Connector page.

Accessing the read-only public folder of someone else's H: drive is relatively simple. Using Safari, or any web browser, enter a URL of the form
https://webdav.cc.lehigh.edu/userid/public/
(substituting the person's Lehigh id for "userid".) Note that the "https" is critical, and you will be required to authenticate using your own Lehigh username and password.

Off-Campus (Lehigh VPN)
Due to security concerns, many types of connections into Lehigh's campus network that are initiated from the Internet (e.g. ISPs) are restricted. With the exception of most web-based services and authenticated email, it may not be possible to establish a direct connection from off campus to computing resources on Lehigh's network. In these situations, you need to establish a temporary VPN connection (Virtual Private Network.) Mac OS X supports the PPTP-type VPN connection used at Lehigh. To set up a VPN with the appropriate settings for Lehigh, a configuration file is available for download (450KB .dmg for Leopard, 445KB .dmg for Tiger ). Once the disk image is mounted, simply click the file LehighVPN.internetconnect and the Lehigh VPN settings will be imported into Internet Connect.) Once configured, using the Mac OS X VPN is as simple as selecting Connect from the VPN pulldown in the menubar.

For more information and manual configuration instructions, see the Lehigh VPN web page.
