There are three Wireless networks avaliable on campus:
- MIT Secure - Requires an athena account. When you connect, you will be prompted for your athena username and password.
- MIT Guest - No account or registration required, but some ports and sites are blocked. Anyone should be able to connect to this account.
- MIT - This is the open version of the MIT network and maybe retired at any point.
As of Sept 8, 2018, Dropbox software requires the sync folder to be on an ext4-formatted hard drive or partition. Since our home directories are NFS-mounted partitions, installation of dropbox software is not recommended anymore.
You still can have dropbox software in an unsupported workaround stup.
1) Pick a workstation that has enough local disk space (ex /scratch/)
2) Once you installed the dropbox software, relocate immediately the sync folder to the local disk space on that particular workstation.
3) Do not run dropbox software on any other Math workstations or Servers. If you do, there is a chance that all your files may be deleted!!
4) Please ask for IT help if you want to pursue this option.
Not at this time. Fedora is currently the only supported operating system on the Math Department network for general use.
When switching between versions, Firefox re-caches the modified time of extensions and language packs. This proccess can take up to two minutes, and can be a real hassle if you do not always use the same browser. To prevent this unnecessary re-caching, follow these steps:
1. In Firefox, type 'about:config' into the URL bar.
2. Scroll down to 'extensions.ignoreMTimeChanges'.
3. Set that field to 'true'.
Firefox should now start much more quickly when switching between computers.
Absolutely. If you are willing to have a computer placed on your desk email firstname.lastname@example.org.
You will need your Kerberos (Athena) user name and password and your MIT ID number.
If you don't have an Athena account, you can get one from the Athena Environment Registration Page at http://web.mit.edu/register/. Once you have your Athena account, you will need to go to https://ist.mit.edu/certificates to get certificates. Scroll down to the heading Get certificates now. Follow the instructions on each link.
We perform nightly backups of our filesystem. To restore a file or directory from backup, send an email to email@example.com and specify the name and location of the file before it was deleted. The proccess or restoration will vary between a minute and an hour depending on the size of the restore.
You will need to complete the 2 factor authentication. The url is http://apps.webofknowledge.com.libproxy.mit.edu/WOS_GeneralSearch_input.do?product=WOS&search_mode=GeneralSearch&SID=2EKG6Nen3UzxOpfuGil&preferencesSaved=.
This usually means that firefox did not shut down properly, and some files have remained locked. Run 'unlockFirefox' from the command line to remove these lock files.
Not at this time. If it is a Microsoft Office document you can use one of the programs listed on the Workstations page.
Please visit our Projector Instructions page for more information.
Please see our information about departures in the policies section.
Mathematica is now provided free of charge to all faculty, staff, and students here: https://ist.mit.edu/mathematica/all
MIT offers Matlab free of charge for students and faculty. You can obtain a license here: https://ist.mit.edu/matlab/all/
We have a license from MIT for Maple. Both Faculty and Graduate students can get Maple for free (certificates required).
Development Environment Adding Startup options for UNIX Platforms include startup options (also called command flags) after the Matlab startup function. The startup options for UNIX are listed below.
Option Description -arch Run MATLAB assuming architecture arch. -arch/ext Run the version of MATLAB with the extension ext if it exists, assuming architecture arch.
-c licensefile Set LM_LICENSE_FILE to licensefile. It can have the form port@host.
-Ddebugger [options] Start MATLAB with the specified debugger. -debug Turn on MATLAB internal debugging. -display Xserver Send X commands to Xserver. -ext Run the version of MATLAB with the extension ext, if it exists. -h or -help Displays startup options. -mwvisual visualid Specify the default X visual to use for figure windows. -n Print environment variables only.
-nodesktop Start MATLAB without bringing up the MATLAB desktop. Use this option to run without an X-window, for example, in VT100 mode, or in batch processing mode. Note that if you pipe to MATLAB using the > constructor, the nodesktop option is used automatically. With nodesktop, you can still use development environment tools, such as the Help browser, by starting them using a function, for example, helpbrowser. Don't use nodesktop to provide a command line interface, if you prefer that over the desktop tools. Instead, select View -> Desktop Layout -> Command Window Only.
-nojvm Start MATLAB without loading the Java VM. This minimizes memory usage and improves initial startup speed. With nojvm, you cannot use the desktop, nor any of the tools that require Java. The restrictions are the same as those described under UNIX Platform Limitations in the R12 Release Notes.
-nosplash Start MATLAB without displaying the splash screen during startup.
For example, to start MATLAB without the splash screen, type
If you're getting Java errors when trying to print, add this environment variable:
setenv MATLAB_JAVA /usr/local/pkg/java/jre
You can put this into your .bashrc, or your .cshrc to get invoked at startup.
