===Announcements===
<startFeed />

==Thanksgiving Break Closure==
The UMIACS Help Desk will be closed from Thursday November 28th through December 1st. We will re-open at 9:00 A.M. on Monday December 2nd.

==Mavericks and Backups==
The most recent version of OSX, Mavericks, is incompatible with our deployed version of Druva. Druva is our backup software and we have upgraded it to support Mavericks. However, you will need to upgrade your Druva client. You can get the latest version of the client [[Druva/setup#Getting_the_client | here]]. Alternatively you can bring your laptop to the helpdesk and we will upgrade it for you.
==Adobe Acrobat Reader on Linux (RHEL/Ubuntu)==
We regret to inform our users that we will no longer be able to provide
this application on our supported Linux systems (Windows and Mac
systems will not be impacted). We will be removing and blacklisting it
from our installed systems during our November maintenance window.

The reason for this change is that there are several known
vulnerabilities in the last version for UNIX systems (9.5.5). Adobe
has declined to fix these issues and has instead deprecated the
product[1]. Adobe has also declined to support a UNIX client in
version 10 or version 11. Red Hat has already advised its users to
disable and remove the application effective immediately[2].

Additionally, due to the recent security breach acknowledged by
Adobe that has compromised their closed source product[3], it is
only logical to expect more vulnerabilities to be found.

As such, during our November maintenance window we will be removing the
application from our systems. We encourage our users to remove it from
any self-supported machines they administer. Please email
staff AT umiacs.umd.edu if you have any further questions.

The following are the alternative PDF readers supported:

RHEL5: evince or kpdf 
RHEL6: evince or okular 
Ubuntu: evince or okular

==Java==
Due to the frequency and severity of recent Java vulnerabilities, it is strongly advised that '''Java be disabled''' in all browsers on your workstations. If you do require Java, it is recommended to maintain a second, '''separate browser''', solely for the instances which require Java. For instructions on disabling Java on your workstation, please see the following: [[JavaDisableBrowser|How to disable Java]]

===Replacing LPRng Print Service With CUPs===

If you are a user of the LPRng print service hosted on lpr1.umiacs.umd.edu please note. We have replaced our print service with a new service based on the CUPs software to provide better printer support and more security. Instructions for using and configuring the new print service can be found at:

https://wiki.umiacs.umd.edu/umiacs/index.php/CUPS

Our old print service will be retired on Thursday, August 18. Please
update
your print setting before then to avoid a disruption. If you require
assistance
updating your printer configuration, you can contact staff, by sending an
email to staff@umiacs.umd.edu. Or you can visit our Help Desk, 3142 AVW,
between the hours of 9am and 5pm.

Thanks for your patience

===Upgraded OpenLAB Desktop===
The desktop called raspberry in Open Lab Computer Room in AVW room 4462 has been upgraded to a newer machine and is now running Red Hat Enterprise Linux 6.

===New UNIX Print System===
We are pleased to announce the immediately available [[CUPS]] print system for our UNIX (rhel/ubuntu) users. Please contact staff@umiacs.umd.edu with any issues.

Ajohnson: /* Adding A Password Protected Folder To Your Web Space */

UMIACS provides web space hosting for research/lab pages and user pages.

==Main Website and Lab Pages==

<pre>http://www.umiacs.umd.edu</pre>

Users can access the main website and lab sites for editing in two ways:
* From Unix as /fs/www - and can be remotely accessed by [[SFTP]] to a supported Unix host (eg. [[OpenLAB]])
* From Windows as \\umiacs-webftp.umiacs.umd.edu\www-umiacs - and remotely accessed by the same file share over the [[VPN]]

==Personal Web Space==

<pre>http://www.umiacs.umd.edu/~username</pre>

Users can access their website for editing two ways:

* From Unix as /fs/www-users/username - and can be remotely accessed via [[SFTP]] to a supported UNIX host (eg. [[OpenLAB]])
* From Windows as \\umiacs-webftp.umiacs.umd.edu\www-users - and remotely accessed by the same file share over the [[VPN]]

In general, large datasets related to a Labs research should go into the specific lab's web tree, not the individual users. Remember that users' webpage is not permanently maintained once the user leaves UMIACS.

==Adding A Password Protected Folder To Your Web Space==

1) Create the directory you want to password protect or '''cd''' into the directory you want to password protect

2) Create a file called ''.htaccess'' ('''vi .htaccess''') in the directory you wish to password protect.

3) In the file you just created type the following lines
 '''AuthUserFile ''/your/directory/here/''.htpasswd'''
 '''AuthName "Secure Document"'''
 '''AuthType Basic'''
 '''require user username'''

For example, if you were going to protect the '''/usr4/test/private/''' directory and you want the required name to be '''class239''', then your file would look like this:
 '''AuthUserFile /fs/users/www/username/private/.htpasswd'''
 '''AuthName "Secure Document"'''
 '''AuthType Basic'''
 '''require user class239'''

4) Create a file called ''.htpasswd'' in the same directory as ''.htaccess''. You create this file by typing in '''htpasswd -c .htpasswd ''username''''' in the directory area to be protected.

In the example above, the username is '''class239''' so you would type '''htpasswd -c .htpasswd class239'''

You will be prompted to enter the password you want. The ''.htpasswd'' file will be created in the current directory and will contain an encrypted version of the password.

To later change the username, edit the ''.htaccess'' file and change the username. If you want to later change the password, just retype the above line in step 3 and enter the new password at the prompt.
