If you need to use your MACS $HOME, say hosting your own personal web pages, in ~/public_html, you will need to mount it using the following commands, this has been setup along with a MACS linux passwd, which you should have received in your HW mailbox. Run the following 2 linux commands :-
mkdir /home/$HWUSER/home_dir
ALL USERS need to do this command the one time, in the /home/$HWUSER directory, to create the mount point used in the sshfs command.

To mount the MACS $HOME each group of student users, need to run the following command
For cs1, cs2, cs3, all ce, gla students :-
sshfs $HWUSER@home-server.macs.hw.ac.uk:/export/home/14/[cs1/cs2/cs3/gla/ce1/ce2/ce3/ce4]/$HWUSER /home/$HWUSER/home_dir
For cs4 students
sshfs $HWUSER@home-server.macs.hw.ac.uk:/export/home/8/cs4/$HWUSER /home/$HWUSER/home_dir
For msc students
sshfs $HWUSER@home-server.macs.hw.ac.uk:/export/home/8/msc/$HWUSER /home/$HWUSER/home_dir
where $HWUSER is your HW username, e.g. abc1234.
For staff and phd students
sshfs $MACSUSER@home-server.macs.hw.ac.uk:/export/home/$PART_ADDRESS/$MACSUSER /home/$HWUSER/home_dir
where $MACSUSER is your MACS username, this maybe different from your HW username, especially for longer serving MACS staff, e.g. imcc -- ceeiam.
$HWUSER being your HW username, which maybe different from your MACS one.
$PART_ADDRESS can be obtained by logging into a MACS linux server and running ypmatch my_macs_username auto.home, giving -

mull( 1027 )ypmatch imcc auto.home
home-server:/export/home/1/staff:&
mull( 1028 )

you need to use the directory between the : for the $PART_ADDRESS.
Hence for MACS user, imcc, the full sshfs command would appear as -
sshfs imcc@home-server.macs.hw.ac.uk:/export/home/1/staff/imcc/ home/ceeiam/home_dir
sshfs will ask for the passwd for the $USER login, use the MACS one, NOT your HW one.

Once this has mounted you can access the MACS $HOME, via cd /home/$HWUSER/home_dir, there should be a directory, public_html in there where web pages should be placed. Other files can be saved in there also, these will be backed up nightly to tape backup. Files,etc placed at the /home/$HWUSER level are saved on the HW file system and backed up elsewhere.

There is a space limit of 10GB, on this /home space, this applies to all users (staff and students).

When you want to end your session, it is advised to unmount the /home/$HWUSER/home_dir with the command - umount /home/$HWUSER/home_dir, as it might not mount the next tuime you want to mount the MACS $HOME.

The MACS Mongo DB Server is mongo-server-1.macs.hw.ac.uk

To access this use
mongo --host mongo-server-1 -u username -p default_passwd --authenticationDatabase username
where username is your HW/MACS username, default_passwd is abcusername354.

Simply right-click on the background and choose "Change Desktop Background" and set your background to a picture or solid colour.

You choose your desktop enviroment when you are logging in, after you enter your username. There are several desktop environments available and which one you choose is largely down to personal preference.

MATE is a fork of Gnome 2 (as used in previous years) and is the default, and that is the one we would recommend to new users.

TDE (Trinity Desktop Environment) is the current version of KDE 3. If you used KDE on CentOS 5 this is very similar.

KDE is the newer KDE version 4.

XFCE is a fairly simple and lightweight, though fully featured, environment.

Gnome is Gnome 3, which has the disadvantage that it can't be used over x2g0, although it can be used locally in the Linux lab.

Cinnamon is a more lightweight fork of Gnome 3, which can be used with x2go.

Type man command where command is the command in which you are interested.

For example, to find out about the 'man' command itself, type man man.

Many programs also have documentation in GNU Info format, type info command.

You will also find various forms of documentation on system packages in /usr/share/doc/package-name-version.

In Linux use the command passwd and you will be prompted to enter your old password then give a new one. The system then makes a few simple checks on your proposed password and if it is o.k. you will be prompted to re-enter your new password so that you & the system agree on what you typed!

To change your password on a Windows system, once you have logged in with the old password, type Ctrl-Alt-Del and choose "Change Password". It is recommended you change the passwd to the SAME as you changed your linux one to, although not necessary.

Choose a password that contains a mixture of letters and digits, upper and lower case, no keyboard patterns, and no dictionary words or it may be rejected.

Use the command ypchsh and follow the prompts but remember that you must give the full pathname of the shell you want e.g. for tcsh give /bin/tcsh.

This facility is not available. You can get in touch with the help desk if your details are wrong.

To run a Servlet from the MACS development web server (ANUBIS) www2.macs.hw.ac.uk:

Place your servlet class into the directory /var/lib/tomcat/webapps/$USER/WEB-INF/classes on the development web server (www2.macs.hw.ac.uk), where $USER is your username.

You must contact help@macs.hw.ac.uk to create this directory for you if it doesn't already exist.

If your intended servlet isn't compiled, say a java source file, you will need to compile the source using the command javac file.java.

The URL required to view your servlet is http://www2.macs.hw.ac.uk:8080/$USER/file, where file is the file.class located in the `WEB-INF/classes` directory above.

You need to create a /var/lib/tomcat/webapps/$USER/WEB-INF/web.xml file which holds the names of all your servlets. You can create this file and add new servlet names to it by running perl /var/lib/tomcat/bin/make-web-xml.pl, This perl will create the initial web.xml file if it does not exist. If the file exists, it will prompt for the new servlet you've created and add it at the end of the web.xml file in your WEB-INF directory.

Here is an example web.xml:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

        <servlet-class>imcc</servlet-class>
</servlet>

<servlet-mapping>
        <servlet-name>imcc</servlet-name>

To run a Java Server Page (JSP) File from the MACS development web server www2.macs.hw.ac.uk:

Place your JSP File into the directory /var/lib/tomcat/webapps/$USER/ on www2.macs.hw.ac.uk. The help desk may need to create the $USER directory for you, as for the servlets above.

The URL to browse your JSP File running is http://www2.macs.hw.ac.uk:8080/$USER/file.jsp, where $USER is the same name as the directory given above.

(Windows 7) File, Save as, choose PDF in the file types.

If you go over your quota limit, here are some examples of areas to tidy up files, i.e. delete them.

Any cache directories for web browsers e.g. below ~/.mozilla/firefox

Other caches e.g. ~/.java/deployment/cache/*

If you have done so, and still have a genuine course-related reason for requiring further space, please contact the helpdesk and explain your needs.

To take screen shots from Linux you can use the command display. Right click in the Image Magick window which will appear to get the menu options, then click `Open...` to grab a screen section or window from your desktop. To save your selection right click in the Image Magick window, then click on `Save...`, click on `Format` for which format (jpg, bmp, tif, etc) you wish the image to be in. Input the file name you want to save the image to, possibly your $HOME directory if you are going use it in an MS Word document.

You can load the saved image into a MS Word document, by clicking on `Insert, Picture, From File ...` within Word, then selecting the file you saved in Linux.

'test' is a shell reserved word - to run your program try ./test if it's in the current directory or else give the full pathname.

There are three labs of Windows 7 machines. These are the general lab in EMB 2.45 and the MultiMedia labs in EMB G.46 & G.47.
