Changing network password for Phonetics and Linguistics network

Your network password required for email, network printing, network disk access 
etc is stored on a Departmental server. The password used to access your PC is stored 
on your PC. These passwords can be the same or different. If they are different you 
will be prompted for your network password the first time you try to access a networked 
disk after logging in to your PC.

Ensure you choose a secure password at least 7 characters long, which is difficult to 
guess, not in any dictionary of any language; no proper nouns, including names of 
"famous" real or fictitious characters; no common acronyms no simple variations of first 
or last names; no more than three characters from a substring of any of the above.
Include a mix of upper and lower case, numbers and other non alphabetic characters.

Any insecure passwords will be detected and the login disabled.
You must change this password at least every 4 months. Otherwise your login will be 
disabled. 
    
To change your network password:-

You need to log in to the Phonetics & Linguistics password server,
bell.phon.ucl.ac.uk using an SSH client program as per instructions below. 
You can't use telnet for this. 

If you don't have an SSH client program on your PC or don't know what one of
these is, get one called putty from:-

http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe

Save this to your Windows desktop then double click on the  putty icon.
On the Putty Configuration menu which appears:-

Click on ssh sothat 22 appears in the window labelled "port"
In the Host Name window enter the name of the computer you want to log in to
such as bell.phon.ucl.ac.uk. In the Saved Sessions window enter an identifier 
for this computer such as bell. Click save. The name bell should appear in 
the window below this.

Now, whenever you want to connect to bell using ssh, double click on the
putty icon on the Windows desktop then double click on  bell  in the window
which appears. This should give the bell login prompt.

On the first connection from a PC it will ask if you trust the computer you
are connecting to is really the one you want. It you accept then you will
not be prompted again from this PC unless the encryption key is changed on
the server.
