Task	URL	Your email addresses	Remarks
create account	https://calmail.berkeley.edu/manage/account/create_account	jane.doe@berkeley.edu	requires CalNet Authentication you have to accept the terms of service your @math address is created by department
access email	http://bmail.berkeley.edu	jane.doe@berkeley.edu jdoe@math.berkeley.edu	requires CalNet Authentication accept the terms of service at first time both addresses point to the same Gmail box you can make jdoe@math.berkeley.edu default

Web

Task	URL	Remarks
read department web pages	http://math.berkeley.edu	no authentication required
edit your official page	/people/path-to-your-page	replace path-to-your-page with the path to your page, e.g. faculty/jane-doe requires CalNet Authentication click on Edit tab of the page you own upload photo, add link, etc.
create/edit your personal page	/~your-unix-login	replace your-unix-login with your Unix login name, e.g. jdoe create public_html folder in your Unix home create/edit index.html file in the above folder make sure the file/folder permissions are right read more in the Webpage Guide

Printing Tasks

Task	Commands	Remarks
print a document from a GUI application (e.g. standalone PDF reader)	press Ctrl-P (in Unix or Windows) press Command-P (in MacOS) select the queue name from the above list of public printers	send large jobs to one of Canon printers use two-sided printing option (save trees) sometimes, a (malformed) PDF document won't print from the web browser, but prints OK from a standalone PDF viewer (e.g. Adobe Reader)
print a document from Unix command line	lpr -P queue file	replace queue with the queue name from the above list of public printers replace file with the file path of the document to print
check the print queue status from Unix command line	lpq -P queue	replace queue with the queue name from the above list of public printers
cancel the job from Unix command line	lprm job	replace job with the job number from the above output of lpq command you have to own the job in order to able to cancel it
add a printer to personal Windows computer	go to Add Network Printer dialogue use the URL from the above list of public printers use a proper Postscript driver (see remarks)	do not use PCL printer drivers, use Postscript drivers instead it is recommended to install the HP universal Postscript driver for the above HP printers it is recommended to install the Canon Postscript (PS3) driver for the above Canon printers
add a printer to personal Mac computer	go to the list of printers in System Preferences click on + sign click on the IP tab select IPP protocol type printserver.math.berkeley.edu in Address type printers/queue in Queue type queue in Name select Generic Postscript Printer click on Add button and check the Duplex Printing Unit click on OK button	replace queue with the queue name from the above list of public printers it is recommended to replace the Generic Postscript driver with a more specific one from the print server itself for example: download the PPD file http://printserver.math.berkeley.edu:631/printers/1002.ppd go to the printer list in System Preferences select the printer 1002 and click on Options & Supplies click on the Driver tab and select Other... use the downloaded PPD file 1002.ppd

Network

Network	Type	URL	Remarks
CalVisitor	public WiFi	http://ist.berkeley.edu/airbears/calvisitor	no authentication required no encryption (public network) limited network service: Web and VPN only
AirBears2	private WiFi	http://ist.berkeley.edu/airbears	requires authentication (AirBears2 key) set or view the key here (requires CalNet Authentication) encrypted (secure) network
eduroam	private WiFi	http://ist.berkeley.edu/airbears	requires (eduroam) authentication UC Berkeley insiders may use their AirBears2 key visitors may use their home institution eduroam credentials encrypted (secure) network
Ethernet	wired	http://www.net.berkeley.edu/dhcp/	requires MAC address registration student personal computers are not eligible for wired network access faculty and long term visitors may send the office number and MAC address of their computer to request@math.berkeley.edu (it takes about 15 min to complete the request upon receiving your email) alternatively, register your computer campus wide via IST network device registration page (registering a MAC address does not mean an immediate access to the network — please be patient)
