Even if you are not on campus, you can still remotely access all the services and subscriptions that are available when you are physically on the campus network. Examples of such services are: [http://www.ams.org/mathscinet/ MathSciNet], [http://www.cdlib.org/services/d2d/ucelinks/ UC eLinks], [http://www.jstor.org/ JStor], etc.

There are two basic ways to do this (see the University library [http://www.lib.berkeley.edu/using-the-libraries/connect-off-campus help page] for details):
# The first method is to use library EZproxy (JavaScript) server (see this [http://www.lib.berkeley.edu/using-the-libraries/proxy-server help page]). Basically, when you click on a resource link found in OskiCat, via "Start your search" on the Library home page, Databases A-Z or eJournals (UC eLinks), you will be prompted to authenticate. You may authenticate via CalNet, or via your PIN / Cal 1 card number. You no longer need to configure your browser to use the old library proxy.
# The other is by connecting using a Virtual Private Network which will establish a secure tunnel to the campus. To do this you must install special software on your computer, the [https://vpn.berkeley.edu/ GlobalProtect VPN Client].

=Computing Support at UC Berkeley Department of Mathematics=

Welcome to the [/ UC Berkeley Department of Mathematics] computing support wiki. We hope to provide useful information to all members of our department. In order to do that, we want to enlist your help. Most pages can be edited by anyone who's logged in. Anyone with an email address ''@math.berkeley.edu'' or ''@berkeley.edu'' may request a wiki account via [mailto:consult@math.berkeley.edu?Subject=Math%20wiki%20account%20request&body=Please%20create%20a%20wiki%20account%20for%20me. consult@math.berkeley.edu]. Feel free to add any computing related help and information.

==Getting Help==
* The primary support email address for computer, printer and network problems within the department is [mailto:request@math.berkeley.edu request@math.berkeley.edu].
* Web related questions should be addressed to [mailto:webmaster@math.berkeley.edu webmaster@math.berkeley.edu].
* For hardware printer problems '''only''', (including low toner), use [mailto:trouble@math.berkeley.edu trouble@math.berkeley.edu].
* [http://sharedservices.berkeley.edu/it/ The Campus Shared Services (CSS) IT] covers wireless network issues, campus wide outages, support of recently purchased office computers, etc. However, CSS are not familiar with the departmental web, Unix, printing and wired network services.
* There is also a consult mailing list [mailto:consult@math.berkeley.edu?Subject=subscribe consult@math.berkeley.edu] for general questions, which is read (and answered) by volunteer faculty knowledgeable about Unix and mathematical software.
Please do not copy more than one of above mentioned addresses on your email. If you happen to send to the wrong address, it will be redirected by someone to the correct one.

CalNet 2-Step Tips

2018-03-23T02:29:02Z

Igor: /* Remember me for 30 days */

==Introduction==
CalNet 2-step verification (a.k.a. 2-factor authentication or 2FA) is a security measure designed to protect your CalNet account from an attacker who have stolen your CalNet credentials. The 1st step of CalNet authentication is usual (filling CalNet ID and pass-phrase in the web browser form). The 2nd step is verifying your identity using a hardware device the attacker can not have (like your smart or landline phone). The 2-step verification is available for faculty and staff, and we encourage you to enroll before it becomes mandatory ('''April 16, 2018'''). The enrollment is easy, takes few minutes and becomes effective immediately.

==Limitations==
* The 2-step verification is tied to campus central authentication service (CAS), that is it works only with web applications designed for CAS authentication. Here are few examples of such applications: bMail http://bmail.berkeley.edu, CalCentral https://calcentral.berkeley.edu/, department website https://math.berkeley.edu/cas, CalNet [https://auth.berkeley.edu/cas/login?service=https%3A%2F%2Fbpr.calnet.berkeley.edu%2Faccount-manager%2Flogin%2Fcas&renew=true account manager].
* You will not be asked to confirm your identity if you login to your desktop computer using CalNet credentials. Neither will you go through the 2nd (verification) step if you access your mail from Unix command line. That means you still must protect your CalNet credentials by all means.
* The 2-step verification process won't do much good if your computer or mobile device is compromised or running unsupported (vulnerable) software. All your university owned and personal devices must comply with [https://security.berkeley.edu/minimum-security-standards-networked-devices-mssnd minimum security standards for network devices].

==Is your web browser safe?==
It is vitally important to keep your web browser safe. Ask yourself these questions:
; Is my browser up to date?
: Update it if the answer is no and you have administrative privileges on your computer.
; Do I have Flash plugin installed?
: It is not recommended, but keep it up to date if the answer is yes.
; Do I have Java plugin installed?
: You might not need it, but, again, keep it up to date if the answer is yes.
; Do I have ad blocker installed?
: It is recommended because it may block unsafe ads.
This [https://www.whatismybrowser.com/ third-party site] might help to answer the above questions. Note that the version of Firefox browser installed on department managed Unix computers is not the latest. This is normal and does not mean that it is not safe. All department Unix systems are updated regularly.

==Enroll first device==
Go to [https://bpr.calnet.berkeley.edu/account-manager/twoStepVerification/manage CalNet account manager] and enroll your first device. The options are:
; smart phone
: Recommended option for technically inclined users. It requires installing an additional app called Duo Mobile.
; tablet
: Not recommended as the first device unless it is always with you. It also requires installing Duo Mobile.
; landline phone
: Recommended option for non-technical users. It may be either a cell or traditional landline or VoIP phone. No additional app needed, but the phone has to be within your reach.
; [https://calnetweb.berkeley.edu/calnet-2-step/enroll-verification-device/simple-hardware-token simple hardware token]
: Recommended option for full-time university employees who do not have a smart phone or tablet device.

==Generate backup passcodes==
It is recommended to generate backup passcodes after you enrolled your first verification device. Just click on the Get Backup Passcodes button at the bottom of [https://bpr.calnet.berkeley.edu/account-manager/twoStepVerification/manage CalNet 2-step manager page], then print the passcodes and keep them safe. You will need them if you lose access to your verification device.

==Enroll another device==
According to [https://calnetweb.berkeley.edu/calnet-2-step/getting-started-2-step/tips-doing-2-step CaNet 2-step tips], you may enroll more than one device. When you get to your second step verification, you can choose which device to use. Select another device from options suitable for the first one plus [https://calnetweb.berkeley.edu/calnet-2-step/enroll-verification-device/other-verification-devices YubiKeys hardware token] intended for advanced users, especially, those who travel a lot.

==Remember me for 30 days==
If you don’t want to do the second step verification each time you log in, you can check the "Remember Me for 30 Days" checkbox before you authenticate. This feature works by setting cookies on your browser and is specific to the browser and computer or device you enabled it on. Thus using a different browser or device will not “remember” you. Check your browser settings to make sure it's not blocking third-party cookies.

==If you get locked out==
If you have lost your phone and don’t have a second device or backup passcodes, contact calnet2-stephelp@berkeley.edu (from personal email account) or call campus shared services at 510-664-9000, option 1.
