 Go to https://www.math.arizona.edu/node/add/az_event

• At the top left, click on Content

• Click on Add Content

Filling out the Create Event Form

Drupal is not as flexible as our previous form so it will take a little bit more effort to get the event to look the way we want.

 Let’s go through each part:

Title:  

Put the name of the seminar with a colon followed by the name of the speaker.  For example:

Mathematics Colloquium: Douglas Ulmer

Subtitle:

Put speaker’s affiliation.  For example:

Department Head, University of Arizona Department of Mathematics

Category:

Choose the appropriate category.  This will most likely be the same as what you entered for title.  Choosing it here creates a page which lists all the seminars in a category.  For example:

Featured Image:

This is optional.

Click on Add media.   You can upload an image or choose from the selection.

When:

Add the date and time.  If you do not want to include a duration (such as 3:30 to 4:30), just make the start and end time the same.

DO NOT use the Repeats feature, unless the same exact event with the same speaker repeats!

Event Description:

This text entry box allows you to enter the title and description and any other information you want.   Please note that it is important to format the title properly for optimal display.

• Type (or paste) the title first. Then select the text and choose Heading 1 from the dropdown menu:

This will make the title a nice size.

• Next you can type or paste the description/abstract. If it appears too large, you may have to change from Heading 1 back to Paragraph

Where:

There are two fields here.  It is helpful to put the “link text” first.  This is just the Building and Room where the event will take place.  The “URL” is the link to the room location on the map.  See Common Math Meeting Rooms URLs.docx for a list of links to our most commonly used rooms.

Here is an example:

Attachments:

Here you can optionally upload a file related to the talk.

Contact:

Here you can optionally add contact information for one or more people.

Saving the Event:

• If you are not ready for the event to be submitted for approval and then posted on the website, choose Save as: Draft.  You can also choose the preview button to take a look at the event before saving.

You can return to a Draft event later to change its status.

• If you are ready for it to be visible on the website choose Save as:    A moderator will be notified to approve and publish the event.

Editing an Existing Event:

When you click on the Content button, you will see a list of your events.  You should be able to edit the events that you created.  After you make changes you will have to submit it for review again.

6.4. VNC - Remote access and control of your Linux Desktop Environment

   hostname.math.arizona.edu:59xx

   vncviewer hostname.math.arizona.edu:59xx

6.5. Setting Up Your VNC Service

• 
  

  The following steps show you how to set up your own persistent VNC server (i.e. remote desktop) which will run  on a computation server or a  VNC gateway.   When you are done with these steps, you will connect  to the server to start a computation job or access your math network files. 

  Setup: starting up the VNC server

  First you will create a VNC server (i.e. virtual desktop.) You can leave the VNC Server running for weeks or months. However, Please do not run multiple VNC servers on the same machine, or on multiple chivos.

  • Pick a VNC host.
    • For light work via VNC, we provide Phoenix (grads) and Dragon (faculty.)
    • For heavy computation, faculty can use their office desktops, grad students can use the chivos
  • Use SSH to connect to the VNC host. You will need to maintain either a Math VPN connection or a SSH Tunnel to the VNC host while using your vnc viewer.
    • For VNC via Math VPN ,
      • First connect to the MATH VPN
      • Then ssh to the machine (ssh to yourmathaccount@vnchost.math.arizona.edu) Replace vnchost with the machine you are connecting to (e.g. chivo, chivoX, yourdesktopname, dragon or phoenix.)
    • For VNC without Math VPN you will instead create an SSH session w/ Tunneling.
  • Use the command vncserver on the VNC host to create your remote desktop. The command will display the number of your new VNC server. EG: ":7", or ":13". You must remember that number! (Advanced users can specify additional options to vncserver. See the bottom of this page for information.)
  • Your remote desktop is now alive! You can use a VNC viewer to connect to your remote desktop.
  • You will be prompted to set a vnc password the first time you create a session. You will need to use this password every time you connect. If you ever forget this password, you can reset it.

  Setup: starting up the VNC server on Ubuntu 16.04 (e.g. the grad chivos).

  VNC server configurations that work on older versions of Ubuntu may not work on Ubuntu 16.04.  If you start your VNC client and see nothing but a grey screen after connecting to the VNC server, follow these instructions to fix the problem.

  • Decide whether you want an xfce4 or a gnome desktop.  The gnome desktop will probably look more familiar, but the xfce4 desktop will be faster and more responsive.
    • If you decide to try the xfce4 desktop, backup your current ~/.vnc/xstartup file and replace the contents with this:

      #!/bin/sh
      
      startxfce4 &

• 
  

• If you decide to stick with the gnome desktop, backup your current ~/.vnc/xstartup file and replace the contents with this:

  #!/bin/sh
  
  export XKL_XMODMAP_DISABLE=1
  unset SESSION_MANAGER
  unset DBUS_SESSION_BUS_ADDRESS
   
  gnome-panel &
  gnome-settings-daemon &
  metacity &
  nautilus &
  gnome-terminal &

6.6. Alternatives to VNC

6.7. Remote Shell Access to Your Network Account

Our shell gateways, reachable worldwide from anywhere on the internet, provide text-only shell access to your network account. (Once on the gateway, you can also connect to other machines in our building network.)

• Faculty/visitor/staff shell gateway: ssh -p 31415 dragon.math.arizona.edu
• Graduate student shell gateway: ssh -p 31415 phoenix.math.arizona.edu

You use ssh to connect to our shell gateways.SCP, and SFTP are also used to transfer files between your network account and other systems.

Your SSH program uses port 22 by default. You will need to set it to use port 31415 when you are not in a Math building. 

Please never run heavy-duty computations directly on the shell gateway. If you are running a compute job you should ssh or VNC to another machine (such as your office desktop, or the chivo cluster for graduate students)

Different ways to connect to the shell gateway:

• If you are running Microsoft Windows download putty:
  • PuTTY [Download], [How to use]
    This elegant tiny SSH client is a quick download and does not require an Installer to be run.
• If you are running Linux or Mac OS X, you can run ssh from the command line, e.g.:

  ssh -p 31415 accountname@dragon.math.arizona.edu

Gateway authentication:

To verify that you are not being duped by a rogue gateway, the first time you try to connect you will be presented with the gateway's RSA or DSA key fingerprint. The correct fingerprints are:

dragon (RSA): ec:0d:8f:56:ff:60:cc:99:69:81:72:13:e8:c7:08:e2
dragon (RSA/Babble): xipod-ryzem-tefud-nevip-nudef-zinoc-mycyk-gucam-kohiz-pucam-boxex 
dragon (DSA): 8f:4c:ca:06:1c:85:91:6c:60:b5:1f:05:50:8c:69:f5 
dragon (DSA/Babble): xohon-nacyv-vivyb-tizuh-debem-narek-sipam-begin-fasys-zades-gaxux

6.8. Running software remotely or in the background

Introduction

If you're doing heavy-duty computation with Matlab/Maple/Mathematica or your own programs, you may have to wait a long time (perhaps days) for your computation to finish. Since you don't want to sit in front of a lab computer for days, or tie up your office computer, you can put tasks in the background, and/or put them on a remote machine. You can then log out and return later to  get your results,  Note that it is very easy to take up too much CPU time or memory with a background computational process. The "chivos" are dedicated to this purpose for grad students.

Commands

Before launching background/remote tasks, you must:

• Learn to use ssh to connect to remote systems.
• Learn to use top or ps, kill, and renice to monitor and manage processes you've started.
• Learn to use &, nice, nohup, and ulimit to launch processes in a desired way.
• For interactive (non-batch) programs: know about ssh -Y, and learn either vnc or screen.

You can type "man command" to get more information on any of these commands.  This article also gives a nice overview.

top

top displays a list of active processes, how much memory and CPU time each process is using and who owns it, etc. If a machine is sluggish, top will tell you why! From within the topdisplay, you can  kill or renice your running processes. Hit ? for some help, and read the manpage: man top. (If you spot someone else's runaway process eating too much CPU, you can email system or the other user . They might not know about it unless you inform them.)

ps

Makes a list of running processes along with additional information. A common invocation isps -aux, which lists a lot of extra information. Another useful invocation is ps -aux -forest, which draws lines to indicate which process spawned which process. (The commandpstree is similar.)

kill

Lets you kill one of your processes. You must know the numeric process ID. You can see the PID in the top display, or you can get a list using ps -aux. Instead of using kill as a separate command, you can access it inside top. Read man kill for more info. Generally you can first send a "kill 15 xxxxx" (where xxxxx is the process ID) and wait a few seconds.  If the process does not die, do a "kill 9". If that doesn't work, then that machine has become unstable and you can contact the computer support staff.

nice

This starts a task with a nice value, which means the task will do a better job sharing the CPU when you try to run other programs or when other users log in to the same computer. All heavy-duty tasks not running on chivos should be nice. Manpage: man nice.

renice

Forgot to start something using nice? Use this to go back and make it nicer. You can also do this inside top.  See: man renice.

&

Putting this after a command puts that command in the background, so that you can continue to give other commands. If you log out, your background task might get killed automatically (to avoid that, see nohup).  If the command  creates windows (e.g., Mathematica &), it will create them even from the background. Most people use & when starting programs like Mathematica so that they don't lose their prompt. (Try it both ways and the previous sentence will make more sense.) See: http://en.wikibooks.org/wiki/A_Quick_Introduction_to_Unix/Job_Control

nohup

To put something in the background so that it doesn't die when you logout, start it with nohup. (e.g. "nohup command &"  ) This works with text-only programs. In other words, the "nohupped" command won't work if it tries to create windows, or needs keyboard input.  The command must send all output to a file. You can use this with your own C/C++ programs, but you can't use it with most software packages. See: man nohup. screen does much more than  nohup.

ulimit

To prevent a program from using too much time or too much memory, you can set limits in a shell, and all programs started from that shell will have those limits imposed. Use ulimit -ato get a list of limits. To confirm you understand what is going on, set various values ridiculously low and try to run your program to make sure it gets stopped by the operating system. Then quit that shell, open a new shell, and set more reasonable limits. Go read man ulimit.

screen

This creates an environment in which you can start an interactive text-only program, such as GAP or Macaulay, or even Mathematica in its text-only non-notebook mode, but you can log out and it keeps going. On any linux machine, e.g. chivo, enter screen, a "screen" process starts with a new prompt. Then you can enter a command, e.g:  nice Singular, then type some Singular commands that will take days to complete, hit "control-A d" and log out. A day later you can ssh  to chivo, do screen -r to reconnect, and you'll be right back in the Singular session. It's very cool. Type man screen on a linux machine for more information.

ssh

From within a shell, you can use ssh user@remote to obtain a shell on a remote system. Then you can issue commands (such as many of the ones described on this page) on the remote system. If you use ssh -Y user@remote then there will also be interactive X forwarding, meaning that programs launched on the remote system can open windows on your local system (assuming you are logged in to a graphical X desktop). You might also want to read about using ssh to obtain remote shell access to your network account.

VNC

This is a graphical version of screen. You can create an entire virtual X desktop and connect to it from home, office, anywhere you can access a web browser. You'll have to read man vncserver and man vncviewer. You might want to read about using vnc to obtain remote desktop access to your network account.

6.9. Transferring Files To/From Your Network Account

6.10. WinSCP for File Transfer

After you open WinSCP you will see a login screen. The hostname will be dragon.math.arizona.edu for faculty/staff or phoenix.math.arizona.edu for graduate students. The port number of 22 is fine, unless you are not on the math network. In that case change the port to 31415

Next you might see a warning like the following:

Finally you get to the transfer file window. You can drag and drop files from your computer (left side) to the server (right side). Files for your webpage should go into your pub_http_internet folder.

6.11. How to Use PuTTY to Connect to a Remote Computer

Start PuTTY by double-clicking its icon.

When a PuTTY Configuration window opens select Session (it should be selected by default) from the Category panel on the left. In the Host Name (or IP address) field enter the name of the computer you wish to connect to. In the Port field replace 22 (the default) with 31415. Make sure that SSH is selected under Protocol (it should be selected by default). Click on Open.

In the new dialog box enter your username and password.

Once you see the prompt, you are connected to the remote computer.

6.12. VNC via SSH Tunneling

  ssh -L 5900:bobcat.math.arizona.edu:59xx -p 31415 bobcat.math.arizona.edu

  vncviewer localhost

6.13. PuTTY - SSH w/ Tunneling

Start PuTTY By click on this icon:

Enter the name of the computer you're creating this connection for. An example would be "dragon.math.arizona.edu". Enter 31415 for the port. Then since we are creating a session we intend to re-use, enter the computer name in the Saved Sessions space as well. Once all that's entered click on the Save button to the right.

Next, click on the plus sign next to the words "SSH" on the left, then click on "Tunnels" from the items that appear below it. That should bring up a window that looks like this:

Enter the Source port of 5900 and the Destination as dragon.math.arizona.edu:59xx, where xx is your VNC desktop number. If you don't have one, you'll need to create your remote desktop service. Then click "Add" and make sure that your tunnel settings appear in the box above where you entered them.
Note: Graduate Students will use phoenix instead of dragon.

Next, you need to scroll the "Categories" box on the left back up and click on "Session". You'll be taken back to the first window. Click "Save" here again to save your Tunnel settings to the Session we've created.

Now you can simply click Open, and an SSH connection will be made with a Tunnel from your localhost to the Destination entered above. In the future, when you open SSH, you will be able to simple double click on the server name in the Saved Sessions window to open the connection.

6.14. How to Use PuTTY to Connect to a Remote Computer

Start PuTTY by double-clicking its icon. 

When a PuTTY Configuration window opens select Session (it should be selected by default) from the Category panel on the left. In the Host Name (or IP address) field enter the name of the computer you wish to connect to (such as dragon.math.arizona.edu or phoenix.math.arizona.edu). In the Port field replace 22 (the default) with 31415. Make sure that SSH is selected under Protocol (it should be selected by default). Click on Open.

In the new dialog box enter your Math username and password.

Once you see the prompt, you are connected to the remote computer.

Removing Malware

Malware, short for malicious software, is any software program designed to cause harm to a computer system or designed to frustrate the user experience. In addition to viruses and trojan horses, this category of software includes spyware and adware. In short, malware constistutes all the software that evil people try to sneak onto your computer, but which you do not want to have on your computer. This page describes the three programs you should run to eliminate malware from a Windows system. (For more information on malware, see the Malware Wikipedia entry.)

Run Malwarebytes Anti-Malware

This program, which has a free version, does a good job of removing malware. Please download malwarebytes, and then install/run the software.

Run Sophos Anti-Virus

See instructions above.
