Purdue Mathematics IT

For security reasons the Department of Mathematics does not allow users from outside the purdue.edu domain to log into our change password web page.

If you are away from the purdue.edu domain and need to change your password you can us the SSH method as describe below. This only works if you know your math password and want to change it. If you have forgotten your password or it has been reset then this method will not work.

1. SSH into bers.math.purdue.edu.

   • Mac OS and Linux have SSH clients in the OS. See man ssh

   • For MS Window OS you can download a simple SSH program called PuTTY which can be downloaded from http://www.putty.org. PuTTY does not require any installation, just double click on the downloaded .exe file to run.

     • Set Connection Type is set to SSH.
     • Enter bers.math.purdue.edu in Host Name field.
     • Click on Open button.
     • At this point a window will pop up connecting you to UNIX computer bers.math.purdue.edu. If a PuTTY Security Alert window pops up then click Yes.

2. Login with your math username and password.

3. At UNIX command prompt enter the command passwd.

4. You will be prompted to enter your current password and then prompted to enter your new password twice.

   • Your new password should be at least 8 characters and contain the following:

     • at least 1 upper case character.
     • at least 1 special character.
     • at least 1 number.

5. The program will let you know if the new password was accepted. You can always CTRL-C out of the passwd program and execute again if you get into problems.

6. Once you have change your password you can type the command logout to exit the session.

BANNER is the new administrative software that maintains student, financial and personnel data. The impact of Banner will result in three important changes beginning Fall 2008:

(1) Course rosters will now be obtained online from Banner (or Blackboard Vista) . The old system SIS will no longer exist.

(2) Final course grades will now be submitted online via Banner (or Blackboard Vista) . The old green sheets will no longer exist.

(3) Plus or minus grades are now possible .
(a) All 100 and 200 level courses are required to give final grades that may include +/- grades (where necessary).

(b) For all single-section courses above 300, giving final grades that may include +/- (where necessary) is strongly recommended.

(c) All multi-section courses above 300 are required to have a consistent policy regarding the giving or not giving +/- final grades (where necessary).

Reminders:
# You must use your Purdue Career Account, not your Math account.

# You must be FERPA (Family Educational Rights and Privacy Act) certified in order to access BANNER (or Blackboard Vista). Certification information is available at: FERPA Certification

# Be aware that you will have access to student data, most of which you don’t need. Privacy and security should be maintained when accessing student records.

More information on Banner can be found through the departmental Banner webpage.

No. Never type your password into an email.

For more information see Is this a real email?.

“Phishing” is an attempt to criminally and fraudulently acquire sensitive information, such as usernames, passwords and other sensitive information, by masquerading as a trustworthy entity (from Wikipedia).

Neither ITaP nor Math IT will ever ask you to reveal your password in an e-mail response, or over the phone, or in person. They will never send you a URL in an e-mail to click on that will ask you for your password; if necessary, they will give you instructions on how to get to a certain web page from the Math department home page or the Purdue home page. Additionally, neither ITAP nor Math IT will ever ask for any sensitive information (your date of birth, your Social Security Number, etc.).

Please feel free to email helpdesk@math.purdue.edu if you’re wondering about a specific email; however, if you have any suspicions about an email, it’s probably spam.

Have you ever forgotten your math password? Has your math password ever been reset due to that 120 day limit?

Instead of waiting for Math IT to reset a forgotten or unknown password, you can now reset it yourself!

All that’s required is that you provide the answers to some questions now. Later, when you wish to reset your math password, you’ll be asked those same questions and will need to provide the exact same answers.

1. Pick and answer the questions on this page: https://www.math.purdue.edu/mathnet/securitychallengequestions/
2. Forget your password.
3. Follow the instructions on this page: https://www.math.purdue.edu/resources/resetpassword to reset your password.

Generally speaking, program updates are important (many updates fix security problems), and while we attempt to automate as many updates as possible, some updates cannot be applied without an administrator’s password. When this situation arises, please send e-mail to helpdesk@math.purdue.edu and we will be happy to help you finish the install process.

Additionally, the many common applications available by opening Finder, selecting [Macintosh HD] and then selecting [Math Applications], are regularly updated by the Math Computer Systems staff.

The Mathematics server computer equipment has all been moved from the eighth floor of the Mathematical Sciences Building to the basement. The scheduled downtime on Wedneesday, March 12th has been cancelled! We hope this move will result in greater uptime and reliability of the Math servers and SunRays. Thank you for bearing with us through this move. Please address any questions, concern or comments to helpdesk@math.purdue.edu The server “banach” is no longer available, please check the list of math computer systems for available machines.

The Department of Mathematics server room MATH-843 (Gauss Haus) has been around for many years. With the increase in our computer equipment and the age of the Gauss Haus infrastructure, such as electricity and cooling, over the last year we started looking at upgrading the Gauss Haus infrastructure.

When we started investigating the upgrade of the Gauss Haus we found that IT@P provided a colocation room in the MATH basement in MATH-B60. After evaluating the cost to upgrade MATH-843 compared to the the yearly cost of the colocation room, we decided it was more cost-effective to move the Gauss Haus computers to MATH-B60 than upgrade the Gauss Haus, which would have been a very expensive upfront cost.

The MATH-B60 colocation room is a controlled access room and we will be provided 1.5 racks of space, air conditioning, and uninterrupted power supply (UPS) electrical power. I believe MATH-B60 is a much better environment for our computer equipment, and with the UPS power we should not have the power disruptions that we experienced in MATH-843.

To move our computer equipment from MATH-843 to MATH-B60 will require computer downtime. To reduce the impact on math users, we have decided to make the move over two days during spring break. The first day will require that the entire network be taken down which implies that there will not be any computer services during this time period. The second day will only require certain computers to be taken down at different times and will only effect different users at different times.

SCHEDULE OF EVENTS OVER SPRING BREAK

MARCH 11, 2008 6:00AM

1. Shutdown the entire MATHNET. All equipment in MATH-843 will be turned off and no services will be available.
2. Move and install computers zorn + Falcon Raid, conon (LDAP server), zada (Web Server), mailrelay + sonicwall firewall, and peano (dhcp server) into racks in MATH-B60
3. Startup computers in MATH-B60 and test that all equipment is up and running and on the network.
4. Startup computers in MATH-843 and test that all equipment is up and running and on the network.
5. At this time all desktop workstations (not including Sunray clients) and laptops should be up and have access to the network. The desktop workstations (not including Sunray clients) and laptops should not be affected by the move on March 12.

MARCH 12, 2008, 8:00AM

1. Shutdown bers, bessel and bohr in MATH-843.
2. Move and install bers, bessel and bohr in racks in MATH-B60
3. Startup bers bessel and bohr and test that all sunray servers are up and running and on the network..
4. At this time all Sunray clients should be be able to connect to a Sunray server.
5. The remaining equipment in MATH-843 will be shutdown and moved in no particular order. Before we move the remaining equipment we will send a shutdown notice to users giving them time to save any data and log off.

NOTE

1. Do not plan on running any long compute intensive applications during this time period as they will be killed.
2. We do not have a time of completion for the two days so we will put status information on the math computing web page. If you cannot access www.math.purdue.edu after 6:00AM on March 11 then assume all systems are down. When the math web server is up up you will be able to go to http://www.math.purdue.edu/computing and find status information on the move and related equipment.

Mac OS 10.5 (Leopard) doesn’t auto-discover printers on Math’s network to the same effect as 10.4.If you have administrative rights on your machine, follow this url:http://localhost:631/admin?op=config-serverand find these lines:

# Show shared printers on the local network.

Browsing On

BrowseOrder allow,deny

BrowseAllow all

You need to add a new configuration setting, so that this section of the config file looks like this:

# Show shared printers on the local network.

Browsing On

BrowseOrder allow,deny

BrowseAllow all

BrowseProtocols cups

• Click the “Save Changes” button, enter the username and password of a user with administrative rights and the cups server should restart.
• Reboot the computer, open up System Preferences, and then the “Print & Fax” pane.
• You should now be able to add the Math printers to your list of printers.
• Again, you need administrative rights to do this.
