| 4 | <p> |
||
| 5 | |||
| 6 | This is multi-line data, executed line by line in their list orders. The |
||
| 7 | restrictions only affect resource modules, but not administration modules. |
||
| 8 | Lines starting with a `<tt>#</tt>' are comments. |
||
| 9 | <p> |
||
| 10 | Each line is of the format <tt>[access conditions]:[host conditions]</tt>. |
||
| 11 | <p> |
||
| 228 | reyssat | 12 | The access conditions is a list of words, which will be ANDed. The available |
| 13 | words are listed in the following table. Each word can be prefixed with |
||
| 20 | reyssat | 14 | <tt>non</tt> to reverse its logical meaning. |
| 15 | <p><center><table border=2> |
||
| 16 | <tr><th>word<th>meaning |
||
| 17 | <tr><td>class<td>The connection is within a virtual class. |
||
| 18 | <tr><td>com<td>The requested module is under the com/ subtree. |
||
| 19 | <tr><td>document<td>The requested module is a document. (not yet available) |
||
| 20 | <tr><td>exercise<td>The requested module is an exercise. |
||
| 21 | <tr><td>hint<td>The request is for hint. |
||
| 22 | <tr><td>local<td>The requested module is under the local/ subtree. |
||
| 23 | <tr><td>recreation<td>The requested module is a recreation. |
||
| 24 | <tr><td>tool<td>The requested module is a tool. |
||
| 25 | </table></center> <p> |
||
| 26 | |||
| 27 | The host conditions can be any host definition, eventually plus time |
||
| 28 | definition as for any worksheets. If the first character of the host |
||
| 29 | conditions is ``<tt>!</tt>'', then the host/time meeting the conditions will |
||
| 30 | be refused access (for the resources meeting the access conditions). |
||
| 31 | Otherwise they will be granted access, and subsequent lines in the |
||
| 32 | restriction definition will be ignored for those meeting the conditions. |
