Install ESA Snap for EPSSCI150

This guide will demonstrate how to install ESA SNAP software for use in EPSSCI150 – remote sensing.

click here to jump to macOS install instructions.

Windows installation instructions

First step is to download SNAP from the ESA website here: http://step.esa.int/main/download/snap-download/

You can download a development version of SNAP 8 from the course’s CCLE site.

This will download an .exe file, which you can click to launch. Because this is a development release of the software, you will have to allow windows to open the installer. My screen is green in this example, but yours may be a different color.

You will then be asked to confirm this installation by a windows utility called “User Account Control”. Please click yes/accept/ok on this prompt.

You should now see this window:

click “next” and accept the license agreement.

After this you will be asked to delete any existing snap data, please choose the default option “Delete only SNAP-internal configuration data (recommended)”

The next screen prompts for an installation directory. Leave this at the default value.

On the next screen make sure all the toolboxes are checked to install

You then will be asked if you want to create shortcuts, and add snap to the start menu. You can leave this with the default settings as well.

the final screen asks about if you want to configure snap to work with python. for now, skip integrating python.


macOS installation instructions

Make sure you have downloaded the macOS version of SNAP 8 from the course CCLE site.

This will download a .dmg file, which you can click to mount on macOS. For this tutorial we are using macOS Catalina (10.15.7) , but the process should be the same for most older versions.

Make sure you select “Save File” instead of “Open With”.

Once the file is downloaded, double click on it to open the installer.

You will encounter a message that says this installer cannot be opened because Apple cannot check if it is malicious software. This is OK, so click ok.

You’ll need to open System Preferences, which you can find by goign to the apple icon in the upper left corner of the screen and selecting “System Preferences”.

Once you have System Preferences open, click on “Security and Privacy”

You should see the message at the bottom of this screen (be sure you are on the “general” tab) and please select “open anyway”

Almost there! you will see another popup which again says the file cannot be opened. Click “open” on this window.

Now you are ready to start the installer (whew) !

You should see this:

Click “next”, and on the next screen accept the license agreement.

you will then be asked to select an option to delete SNAP user Data. Select the recommended option.

Now you are prompted to pick an installation destination. Leave this as the default value as well.

the next screen will ask you to select which components are going to be installed, check all the boxes

the following screen will ask if you want to configure SNAP to use Python. For now, leave this unchecked.

The Installer will now install SNAP, and when done prompt you to launch SNAP, which you should do.

Snap should ask you to install updates to plugins. You should choose yes.

Congratulations, you are done!

New Grads Computing Information

(or for anyone new to EPSS!)

Welcome ! Below is a list of relevant information for new graduate students in EPSS in no particular order.

Internet Access

To get connected to the outside world, you can use either a hardwired Ethernet connection, or WiFi. Offices the building have Ethernet ports which look like this:

Ethernet Jack from Geology

The Easiest way to get connection is to email a photo of this box to helpdesk@epss.ucla.edu, and tell us which port you are going to be using. We can then remotely configure the ports to connect. You can also email us without a photo, and we can setup a time to come examine your office and help get you connected!

Wifi

UCLA and EPSS have many different WiFi networks, and your Lab, or research group may also have their own WiFi network. For official department business, we recommend that you use EDUROAM, which you can read more about here: https://www.it.ucla.edu/news/eduroam-wireless-network . For many tasks, such as printing to the department printers , this is the only wireless network that is supported.

Email

Most of you should already have a UCLA email through google apps. If you have not yet, please contact Bruin Online for help setting one up.

EPSS Also provides the option to have an @epss.ucla.edu email address. This service is provided by a different campus entity, and is not required. However, if you would like to have a department branded email, just click here and fill out the relevant information!

Printing:

You all will be given a copy code to use the Ricoh multi function printers in the copy room. These devices can be used for black and white, or color printing of materials relevant to your research and studies. These can be printed to from your office, over wifi, and at the device itself using a USB drive. You can read more about setting up the connection yourself here or you can email us to help you.

TA’s will also be given a separate code to use for class related materials.

Computer labs

EPSS has two student computer labs, one in Geology 4691 and Geology b707. Any Student is welcome to use the labs, which have a combination lock. The code can be obtained from the helpdesk if you have forgotten it.

Software:

EPSS licenses some software for use in the computer labs in the department including:

  • Matlab 2019
  • ArcGis Pro
  • Microsoft Office Pro Plus
  • Adobe Acrobat pro( PDF editing)
  • and More!

Students are all covered for Windows 10, Office Pro plus, and Adobe Acrobat pro. Please email the help desk if you need to install any of these, which are available for free to students in the department. We can install this on your personal devices as well. When in doubt, ask us!

Remote Access

Remote Access to EPSS Networks- RDP Edition

Remote access to EPSS department networks is a commonly requested service. Upcoming changes in our network mean that there are a few steps you have to take to connect.

For the purposes of this document, we will cover remote desktop connections for windows hosts, using Remote Desktop Protocol (RDP). Other methods and OS’s are coming soon.

What do you need to remotely connect to your computer?

  • A static ip address. These can be requested from the helpdesk. Grad students seeking remote access should email the helpdesk an their Advisor/Lab PI
  • An account on the windows machine you wish to log into.
  • A ucla login ID (needed for VPN access)
  • A computer that YOU OWN and can install remote desktop client from Microsoft. (installing this on a public computer, such as a library
  • The computer must be powered on here at UCLA.

*at this time, home Linux users should consult with the helpdesk about connecting to windows hosts

Step 1 : VPN

In order to access the EPSS network from off campus, you will need to tunnel your connection through the UCLA VPN. Instructions for installing and configuring the VPN are here: VPN INSTALLATION

Step 2: Enable remote desktop service

On the machine you will remotely access (this step needs to be done at the machine, not remotely) you need to allow remote access. This setting is OFF by default on windows 10.

  • Navigate to start>>settings and in the search bar type Remote Desktop
  • You will see an entry called “Remote Desktop Settings”
  • Click this, and flip the switch “Enable Remote Desktop” to “on”
  • You will be asked to confirm this, click ok
  • Once this is active, you will see two check boxes below.
  • Turn ON the “Keep my PC awake for connections when it is plugged in”
  • Turn OFF ” make my PC discoverable on Private Networks to enable Automatic Connection from a remote device”
windows settings showing remote desktop selection
select the top item from this drop down
remote settings showing authorized users view.
Make sure your account has access.

Step 3: User Accounts, IP address

The Username, and password you will use to connect from your home/away machine to the network are important, as is the IP address you will connect to. Remember to request a static IP first! If you don’t, there is a chance that your computer’s address will change while you are away, and you wont be able to connect.

  • You need the static IP of the computer you want to connect to. This will be a number like 169.232.144.244, or 128.97.31.89
  • To get the ip of your machine, open a command prompt (search for “CMD” from start menu) and type “ipconfig” and hit enter.
  • you will see a lot of output, but you are looking for the “Ethernet adapter” setting.
  • write down the address listed under ” IPv4 address”
command prompt window showing output of ip config
You will need this address to connect to

You will also need the user account name and password that you use to log into the computer when you are on site. Write these down, (but not in an email!!!) you can obtain the username by clicking on Start>settings>Accounts.

Step 4: Connect!

The best way to test this is to have the computer you want to use to connect here on campus. (because if you run unto issues, it is much easier to help you!) Obviously if you have a desktop at home, or that is not possible, you will have to test connection from off site.

  • To test the connection, open the remote desktop client on the computer you want to connect with.
  • If you are testing from on campus, connect to PhySciOpen WiFi network (this will simulate an off campus connection) EDURoam will not work for testing reliably, and may cause the remote connection to work but not from off campus. if you are off campus, skip this step.
  • Open the Cisco AnyConnect VPN client you installed in step 1. type your UCLA login id and password, then wait for the DUO authentication message.
  • AFTER you are connected to the VPN, open remote desktop client. (if you have a macOS machine at home, you can download this from the app store.)
  • In the “computer” (or PC name on an apple device) field, type the Ip address from step 3
  • Click on “show options”
  • In “username” enter the username you would use to log into the remote machine from step 3
  • You can optionally select “allow me to save credentials” and save the connection information for later use (this means you can click a shortcut to connect in the future, but only do this step on a off campus computer that is under your control.
  • you may see a notice, saying that the computer you are connecting to has a certificate that couldn’t be verified. you can ignore this message.
  • If all goes well, you should get a full screen view of your remote computer!

Remember not to shutdown the remote session, or you will not be able to log back in from offsite!

Barracuda Spam Filter

This tutorial will demonstrate how to access the Barracuda spam filter, which protects your @epss.ucla.edu email address.

Sometimes, a message is marked as spam unintentionally and will need to be approved for delivery. This guide will walk you through the steps to log into the barracuda, and to approve messages, whitelist/blocklist addresses, and manage your accounts spam filtering.

The barracuda service sends emails periodically to your @epss.ucla.edu account, which outlines the current held/blocked messages sent to your account. These messages originate from <<emit@cts.ucla.edu>>. If you can’t find them or you don’t have a current message, the spam filter interface can be accessed at https://Nospam6.ad.ucla.edu

baracuda login screen

Once you are here, you can log in, using your @epss.ucla.edu email and your password. Most likely, your password is not valid due to some changes made last year by Barracuda, and you will have to reset your password. This password is ONLY valid for this service and is not connected to any other accounts. To reset the password, click on the “CREATE NEW PASSWORD” button at the bottom of this window, and look for an email to arrive at your @epss.ucla.edu address. (Additionally, make sure you have entered your@epss.ucla.edu email in this dialog box, and no other address has been auto-filled!)

Once you receive the email, log in using your @epss.ucla.edu email address, and the new password. You will see a screen that looks like this:

logged in barracuda view.

Click on the “preferences” tab at the top of the screen to change your password to something memorable, edit the block list settings and other settings.

From the “Quarantine Inbox” tab, you can deliver held messages, add addresses to the Whitelist and permanently delete messages. Messages not deleted or delivered will be Automatically purged after 30 days, so it’s important to do this at least once a month.

And as always, feel free to contact the Helpdesk with any questions or concerns.

How To Use The Department Printers

The EPSS copy room in Geology 3607

EPSS provides two Ricoh MFD high capacity printers for use in the department. These are located in Geology 3807 (across from the Main Office). The use of these printers is open to all department members, but requires a user code to be used. You can obtain a code by emailing helpdesk@epss.ucla.edu with your name, affiliation (what lab/group) and your status (faculty, student, researcher postdoc ect)

Large classes such as EpsSci 8, 9, 10 ect. are issued their own codes, since the printing requirements for these classes is very large. If you are a TA for one of these courses, you can contact the TA coordinator, or email the helpdesk to obtain the user code for those classes.

These devices can print black and white or full color, and can also scan documents and email them to you. A USB flash drive, (must be FAT formatted to be read) can be used as well to both provide documents for printing (PDF and IMG formats only) or to store scanned files, if you do not want them emailed.

Once you have a user code, or if you have one already, follow these steps to install and use the printer. the instructions are different for macOS and Windows machines (printing from Linux is possible, but not supported at this time, if you need this function, please email the helpdesk)

For both platforms

Go to https://ricoh-usa.com and click on support and downloads. Then in the search box type “c6503”

Screenshot of ricoh website with string filled in search box.

then click on the name “MP c6503” under the drivers icon to navigate to the download page. you will be asked to agree to the Ricoh terms of service, please click yes.

The website should automatically select your operating system. for macOS computers there should be one PS driver option. For windows machines, please select the PCL6 driver once this has downloaded, please install the driver.


Windows specific instructions:

To add the printers to your computer, you will need to be connected to EPSS ethernet network, (wall jacks) or connected to EduRoam (wireless), in the Geology/Slichter building. You may encounter difficulty if you are connected your lab/group’s own wireless or switch. PhySciOpen will also not work. If you have trouble, just email the helpdesk and we can assist you.

Once you have downloaded the driver as listed above, the process is the same for both machines (color and black and white). For this tutorial, we will focus on the MP C6503, color copier. Download the driver as above, but for the windows 10 machines, select the PCL 6 driver.

arrow showing the correct driver version to install.

Download the driver installer, then you will be given the option to unzip the contents of the driver. (if you are given a security warning, its ok to continue) when you see the dialog below, click unzip, and when the process is complete, copy the highlited text from the box and paste into a file browser.

win zip window

So, in this example, we would copy “c:/temp/z80159L15” into the file browser, then hit enter to navigate to the folder, like so:

Which will bring you to the temp folder. click on “RV Setup” to launch the driver installer.

open RV_SETUP.

When the dialog box appears to ask if you want to allow the program to make changes click ‘yes’. You will be prompted to answer a few questions by the installer, answer ‘yes’ to the first question and then select ‘network’. The installer will try to find the printer on its own. If you see the Ricoh printer in the list, please select it and continue to “FINAL STEP” below.

Otherwise, if you see this message:

error

You should click ok and then click on the “click if you cannot find the device” button, then “specify device ip address” button.

cant find device button
specify ip address screen.

Now you can enter the IP of the printer manually.

  • If you are installing the c6503 driver for the color printer you must use 128.97.31.249 as the ip address.
  • For the MP 7503 black and white printer, use 128.97.31.241

If everything goes correctly, you should see the printer in the list, and can install it!

FINAL STEP!

Once you have installed the printer, you need to add your job code to the printer dialog, otherwise your jobs will all be discarded by the printer. Go to: Start menu >> Settings >> Devices >> Printers and Scanners.

devices settings
printers and scanners

If you DON’T see the Ricoh device listed here, something went wrong! (dont worry, just email us!) . Otherwise, select the Ricoh device and click “manage”

manage button.

Then select “Printing Preferences”.

select printing preferences.

And navigate to the Detailed settings tab, select the “job setup ” menu from the vertical items in the center menu and fill out your personal Job code in the “USER CODE box. click apply and YOU ARE DONE!

setup screen.

If you have any problems, or even after this, you are unable to print, please reach out to us!


Instructions for macOS

On macOS, the setup of these printers takes two extra steps. Another important caveat is that unfortunately you cannot print to these printers from Safari. We have been in contact with Ricoh about this issue, and it seems it rests with how Safari implements their print drivers and settings. Any other browser will work (chrome, Firefox, edge ect).

  1. Open system preferences.
  2. Select “printers and scanners”
  3. to the left, in the window called printers, you will see a plus sign (+) at the bottom of the window. click this to add a printer.
  4. If you are connected to a wall jack on EPSS networks:
    1. On the network you should see two Ricoh printers at the bottom of the list with “bonjour multi function” listed under ‘kind’
    2. select the printer you wish to add, then wait for the fields at the bottom of the screen to populate.
    3. the field ‘use’ will likely default to “secure air print” which you will have to change to the “Ricoh XXXXX” value.
  5. If you are on Eduroam:
    1. if you are on Eduroam, you will have to add the printers by IP address. 128.97.31.241 is the black and white printer, and 128.97.31.249 is the color c6503.
    2. to add an IP printer, at the top left are of the ‘add’ window, you will see a grey globe icon that says IP. click on this icon.
    3. then enter the ip of the printer you wish to add.
    4. if this is successful, you should see the fields on the bottom of this window populate. be sure that under ‘use’ the proper printer model driver is selected.
    5. continue to the “adding job code” steps below this list.

Adding job Code on MacOS

This step assumes that you have already installed the Ricoh drivers, and that you have added the printers to your system using the steps above. Other methods may work to add the printers, but they will fail silently. To add a job code on macOS, you will have to use a print dialog from an application, such as word, PowerPoint, or a web browser other than safari.

For this example, we will use MS word.

  1. Open any word document.
  2. Open a print dialog (file>>print)
  3. Select the Ricoh printer you wish to use:
  4. Under the “presets “menu you should see a dialog dropdown called “copies & pages”, click this and select “job log”
    1. if ‘job log’ is not showing, its possible you need to reboot to fully add the printers, or there was a problem in adding the printers in earlier steps
  5. Under job log, you will see a box called “enable user code” and a field below to add you code. check the box and type your code into this field.
  6. Then, to save this setting, and avoid having to enter the code for every print job, click on the “presets” dropdown menu, and select “save current settings as preset”

How to use a Mac in the EPSS computer lab

Geology 4691 has 12 dual boot Mac mini’s, currently running windows 10 and macOS Mojave.

These computers can be used with your EPSS account.

The computers boot into the last OS that was selected by default, so to change OS, you should restart the computer, holding the option key, to launch bootcamp. (bootcamp is apple’s boot-loader, and allows you to tell the computer which OS to use when starting up.)

After you have booted into macOS, you will see a row of user accounts. if you do not see a gray circle named “other” you should wait a moment, the Mac needs to connect back to the account server.

Once it appears, click “other” and log in with your epss account credentials.

This will generate a local user account for you on that machine.

IMPORTANT:

On the Windows machines, your desktop, downloads, documents and other folders are automatically synchronized with the server when you log out. This DOES NOT HAPPEN on the Mac side.

You will need to click the blue globe in the dock to access your network storage.
