Department of Computing FAQ

1) How do I connect to Igor from within the University?

You can connect to Igor using a program called 'Secure Shell Client' which is installed on all Windows PC's in the Department's labs. Igor does not allow connections using traditional Unix programs such as telnet and ftp as these are fundamentally insecure protocols which can leave servers open to attack from hackers.

2) How do I connect to Igor from outside the University?

To connect to the DoC server Igor from outside the University, you will need an account with an Internet Service Provider (ISP) that provides you with a connection to the Internet. You can then connect to Igor using a secure shell client (see 2 above) at the following address:

  igor.gold.ac.uk

3) How can I access my files on Igor from Windows?

Within the Goldsmiths network, Windows allows you to access files residing on local network servers (such as Igor) as if they were actually stored on your own PC. This is done by 'mapping' your space on the server to a virtual disk in Windows, which you can then use as if it were an ordinary disk (like the C: drive).

To map your space on Igor, do the following:

  1. Start Windows Explorer.

  2. From the 'Tools' menu, select 'Map Network Drive'. A dialog box will appear.

  3. Select any unused drive-letter to use for the virtual drive (unused drive-letters have no text after the letter in the list).

  4. Enter the following into the 'Path' box:

    \\igor\homes

  5. Ensure that the 'Reconnect at logon' checkbox is checked.

  6. Click 'OK'

You should then be able to access your space on Igor using the drive-letter you selected above.

4) How do I publish my web-pages on Igor?

Publishing web-pages on Igor is simply a matter of creating a directory called 'public_html' within your home-directory on Igor and copying your HTML (and related) files into it. Your pages will then be visible on the World-Wide-Web.

For example, suppose user ma007 copies a file called mypage.html to their public_html directory. This page could be accessed using the following URL:

http://doc.gold.ac.uk/~ma007/mypage.html

If your browser displays a message something like 'Forbidden - You do not have permission to access this page', you will need to change the default file-permissions of your files on Igor to make them accessible. To do this, you need to connect to Igor using 'Secure Shell Client' (or equivalent) and type the following two lines:

chmod o+x $HOME $HOME/public_html
chmod o+r $HOME/public_html/*

The first line makes your home-directory and your public_html directory accessible and the second line makes the files within public_html readable.

5) Why can't I login on the computers in WB300/WB316?

If you can login to computers in the library but not in the DoC labs (WB300/WB316/HH15/HH16), it may be that you need to be added to the DoC user group. This is usually because you are an international student or are taking an DoC course as part of a degree run by another department.

If this applies to you, please send an email specifying your username to sysadmin@doc.gold.ac.uk to get yourself added to the DoC user group.
