Jwhiteis: Added mention of automated cleanups for scratch directories

UMIACS recommends that any and all important data be stored on a redundant, backed-up file server. However, there are a number of cases where this is not feasible.

==Windows Local Storage==
Windows hosts at UMIACS store user directories on their local C drives. Supported, UMIACS-managed hosts automatically back up user data on the C drive nightly using the Institute's backup system. If you have a supported, UMIACS-managed host that has other internal or external hard drives attached to it, or partitions other than C on its primary hard drive, please be aware that these drives/partitions '''are not''' backed up. Laptops and non-standard hosts are not automatically backed up and should be manually backed up by their users.

==UNIX Remote Storage==
We provide storage to each of our users in our UNIX offerings through the [[OpenLAB]] [[NFShomes]].

This home directory,

/nfshomes/username

is backed up nightly into our [[TSM]] backup system. This volume has [[Snapshots]] enabled for easy user restores.

Users are given a 20 gigabyte [[Quota]].

==UNIX Local Storage==
UNIX machines use redundant, backed-up network file shares for user directories. Research data storage is also stored on redundant, backed-up network file shares and is generally available under /fs/

All UNIX machines also have local storage available for transitory use. These directories may be used to store temporary, local '''''COPIES''''' of data that is permanently stored elsewhere or as a staging point for output.

These directories may not, '''''under any circumstances''''', be used as permanent storage for unique, important data. UMIACS staff cannot recover damaged or deleted data from these directories and will not be responsible for data loss if they are misused. Additionally, these volumes may have an automated cleanup routine that will delete unmodified data after some number of days. You can check the page for the specific cluster you are using for more information.

Please note that '''/tmp''' in particular is at risk for data loss or corruption as that directory is regularly used by system processes and services for temporary storage.

These directories include:

- /tmp
- /scratch0, /scratch1, ... (/scratch#)
- any directory named in whole or in part "tmp", "temp", or "scratch".

==Locally Attached Storage==
Locally attached storage like USB flash drives and USB hard drives are very popular. However, these devices are significantly more vulnerable to data loss or theft than internal or networked data storage. In general, UMIACS discourages the use of locally attached network storage when any other option is available. Please note that these devices are prone to high rates of failure and additional steps should be taken to ensure that the data is backed up and that critical or confidential data is not lost or stolen.

==Network Scratch Storage==
Some labs have network-attached storage dedicated for scratch/temporary storage. These shares are named in the same manner as local scratch or temporary storage (i.e. /fs/lab-scratch or /lab/scratch0 ) and are subject to the same policies as local scratch/tmp (discussed above.)

==UNIX Storage Commands==
Below are a few different CLI commands that may prove useful for monitoring your storage usage and performance. For additional information, run <code>[command] --help</code> or <code>man [command]</code>

df - Shows descriptive file system information
<pre>
Usage: df [OPTION]... [FILE]...
Show information about the file system on which each FILE resides,
or all file systems by default.
</pre>

du - Shows disk usage of specific files. Use the -d flag for better depth control.
<pre>
Usage: du [OPTION]... [FILE]...
or: du [OPTION]... --files0-from=F
Summarize disk usage of each FILE, recursively for directories.
</pre>

free - Shows current memory(RAM) usage. Use the -h flag for a human readable format.
<pre>
Usage:
free [options]
</pre>

quota - Shows quota information, this is useful for viewing per filesystem limits in places such as a home directory.
<pre>
quota: Usage: quota [-guqvswim] [-l | [-Q | -A]] [-F quotaformat]
quota [-qvswim] [-l | [-Q | -A]] [-F quotaformat] -u username ...
quota [-qvswim] [-l | [-Q | -A]] [-F quotaformat] -g groupname ...
quota [-qvswugQm] [-F quotaformat] -f filesystem ...
</pre>

iostat - Shows drive utilization, as well as other utilizations. Pair this with the <code>watch</code> command for regular updates.
<pre>
Usage: iostat [ options ] [ <interval> [ <count> ] ]
Options are:
[ -c ] [ -d ] [ -h ] [ -k | -m ] [ -N ] [ -t ] [ -V ] [ -x ] [ -y ] [ -z ]
[ -j { ID | LABEL | PATH | UUID | ... } ]
[ [ -T ] -g <group_name> ] [ -p [ <device> [,...] | ALL ] ]
[ <device> [...] | ALL ]

</pre>

Accounts

2022-01-24T21:33:31Z

Jwhiteis: Added section that describes the new account management page.

This page outlines the various account types at UMIACS and their management methods.

'''Do not share any UMIACS-affiliated account for any purpose. Action may be taken against your account if you do so.'''

==UMIACS Account==
A traditional UMIACS account consists of the following components:
; [[ActiveDirectory | Active Directory Account]]
: Provides access to UMIACS-supported computers, email, [[SecGroups | secgroup]] controlled resources, web services, and the [[VPN]].
; [[Jira | Jira Account]]
: Provides access to the JIRA Request Tracker. Please note that it is possible to set a separate password for this account, at which point it will no longer be synced from your Active Directory Account. Changing your Jira password DOES NOT change your Active Directory Account password.

==Guest / Collaborator Account==
; [[Accounts/Collaborator | Collaborator Accounts]]
: Sponsored account to provide temporary access to UMIACS Web Services for non-UMIACS collaborators.

==Request a UMIACS account==
Fill out the account request form located at the [https://intranet.umiacs.umd.edu/requests/accounts/new UMIACS Account Request webapp]. Please note that for the PI field you will be entering your PI/Professor/Sponsor's account name here at UMIACS. Also indicate any labs you are a member of in the notes field to speed up access to your lab's resources.

Once the form is submitted, it will send an email with a link to verify your email address. You must click this link to verify your email address before the system will send email to your PI to review the account request. Accounts can take anywhere from a few hours to a day for installation, depending on how quickly your PI approves your account.

==Password Requirements==
We have the following policies in regards to our [[ActiveDirectory]] passwords:
* Minimum Password Length : 8 Characters (more is allowed)
* Minimum Character Classes : 3 Character Classes
** English uppercase characters (A - Z)
** English lowercase characters (a - z)
** Base 10 digits (0 - 9)
** Non-alphanumeric (For example: !, $, #, or %)
** Unicode characters
* Password cannot contain (or match a substring of 3+ sequential characters) of your username or any part of your first or last name.
* Password was not previously used in last 5 passwords.
* Password has not been [[CompromisedPasswordFiltering | compromised]] in a known data breach.

It is your responsibility to secure your password. Please try to choose a strong password and use secure protocols.

==Changing account password==
===If you know your current password===
# You can use the [https://intranet.umiacs.umd.edu/password UMIACS Password Web Application] to change your password.

===If you do not know your current password===
# You can [https://intranet.umiacs.umd.edu/password/forgot reset your password yourself] if you have already registered a mobile phone number and alternate E-mail address in our [https://intranet.umiacs.umd.edu/directory/directory/info/ Directory Application].
# If your account was a UMIACS Collaborator Account, your password can be reset by your sponsor via our [https://intranet.umiacs.umd.edu/requests/accounts/collaborators/ Requests Application].
# <s>You can stop by the UMIACS Help Desk in room 3109 Iribe Center with a photo ID.</s> (not currently applicable)
#* <s>If you are unable to physically stop by the UMIACS Help Desk, you can have your Account sponsor (PI) stop by the UMIACS Help Desk to reset the password on your behalf. The account sponsor will then be responsible to conveying the password to you in a secure manner. (i.e. Telephone, where they could identify you by voice)</s>

==Sponsored Accounts==
You can view a list of the accounts you sponsor in the [https://intranet.umiacs.umd.edu/requests/accounts/sponsored/ UMIACS Account Management Web Application]. Clicking on an account's display name will bring you to a management page where you can see details such as the installation date or email forward. From here you can edit your relationship to the account.

You can also request to remove your sponsorship or modify the expiration date, but these require staff action and are not immediate.

Accounts/Collaborator

2022-01-10T16:59:26Z

Jwhiteis: Added self service collaborator updates

A Collaborator account is a sponsored provisional account for non-UMIACS members that provides access to UMIACS applications such as [[GitLab]], [[OBJ | Object Storage]], and MediaWiki instances. Collaborator accounts do not provide login access to UMIACS computers or access to networked file storage. Any access to [[GitLab]] repositories, [[OBJ | ObjectStore]] buckets, etc. fall under their account sponsor and/or the PI. Access to your group's resources is mediated through Security Groups, which can be managed in our [https://intranet.umiacs.umd.edu/directory/secgroup/ UMIACS Directory Application].

==How do I create a Collaborator Account?==
A UMIACS Account holder has to sponsor the Collaborator Account. This is done in our [https://intranet.umiacs.umd.edu/requests/accounts/collaborators/new UMIACS Requests Application]. This will send an email to the Collaborator to set their details (including a username and password). Once the Collaborator has created their account, an email will be sent to both the account sponsor and the Collaborator that the account is ready to use.

==How do I manage my Collaborator Accounts?==
This can be done in the [https://intranet.umiacs.umd.edu/requests/accounts/collaborators UMIACS Requests Application]. You can view a list of Collaborators that you directly sponsor. The following management actions are available:
* Send Password Reset: The account sponsor will generate a token and send email to the Collaborator with a link to reset their password.
* Remove Sponsorship: Staff will be notified to remove the selected accounts from your sponsorship.
You can also view Collaborators who are sponsored by users that you sponsor. Actions include:
* Take Over Sponsorship: Staff will be notified to transfer sponsorship to you, and the original sponsor of the Collaborator will be notified.

==Installation==
This page outlines the steps required to install MongoDB on a supported workstation.

We are no longer supporting MongoDB due to changes in their licensing a few years ago, but you can install MongoDB as a tarball using the following links:
* https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat-tarball/
* https://docs.mongodb.com/manual/administration/configuration/#std-label-base-config

==Steps==
# Download the right Community Server file from the [https://www.mongodb.com/try/download/community MongoDB Community download page] and place it in a directory you own. For most people this file will be:
#* Version: Current
#* Platform: RedHat / CentOS 7.0
#* Package: tgz
# You will need to create a custom mongod.conf configuration file, using the second link above as a guide. The important thing is to set a custom path for <code>systemPath</code> and <code>dbPath</code>. These must be directories that you own. Other than that, they can be anything you choose.
# Start the mongo server: "/path/to/bin/mongod --config /path/to/mongod.conf". Since you are using a custom .conf file you will need to specify this when starting/stopping the server.
# Start the mongo client: "/path/to/bin/mongo".
# Once you are done, you can stop the server with "/path/to/bin/mongod --config /path/to/mongod.conf --shutdown".

== Connecting through the Pulse Secure client (for computers WITH ARM processors) ==
ARM processors cannot natively run x64 or x86 programs without special emulation. Microsoft Surface laptops do not have x64 emulation yet, but they do have x86 emulation. However, not all x86 programs run smoothly even with emulation. As such, the best course of action for these sorts of machines is using the version of Pulse Secure that is specifically made for ARM processors, which is offered on the Microsoft Store.

##Connection name: UMIACS
##Server name or address: vpn.umiacs.umd.edu
##Username: You can put in your UMIACS username if you'd like, or you can leave it blank.
##password: Leave it blank for security reasons.
##Choose to remember sign-in info ONLY if the password field is blank, for security reasons.
##You should now be finished with adding the VPN connection.
#Now under "VPN" and "Add a VPN connection" at the top, you should see a button that says "UMIACS". Click on that button.
#You will now be prompted for your username (if you did not fill it out when adding the connection) and password. Enter your UMIACS credentials, then click the "OK" button.
#You will now be prompted for a "secondary password". This refers to the method of multi-factor authentication you would like to use. Typing in "push" into this field will send a notification to the Duo app on your smart device, whereas "phone" will send a call to your registered phone number. Enter your choice of authentication, then click the "Next" button.
#After completing the multi-factor authentication via push notification or call, you should now be connected to the UMIACS VPN!

In case you would like to manually disconnect from the VPN, go to the same "VPN Settings..."/VPN page in Windows settings, click on the UMIACS connection, and click the "Disconnect" button.

Jwhiteis: Updated naming standard for printers.

==Printer Queues==

UMIACS uses a centralized print server to manage all of the printers in the Institute. See [[Printing]] for more details specific to your OS. We have developed a naming scheme for our printer queues based on the colors the printer can produce, the type of queue, the building number, and the room number.

The naming scheme is as follows:

* All color printers begin with a "c". Black & white is the default so nothing extra is needed.
* Then either "ps" for a PostScript-enabled queue or "pcl" for a Printer Command Language-enabled queue will appear. PostScript and PCL are types of printer drivers. If you are unsure what this means, use "ps" for PostScript.
* Then add the building number and a dash ("-"). E.g. add "432-" for IRB, or "115-" for AVW.
* Then add the room number. E.g. If the printer is in room 3208, add "3208".

Some examples:

* ps432-3208 is a black & white printer in Iribe 3208.
* cps115-4430a is a color printer in A.V. Williams 4430.
