Once you are finished customizing your ipfw rule set, you can start looking into reviewing the logs that you set up to receive from your firewall. These can be pretty lengthy because many systems receive a lot of traffic. You can tell ipfw to log every packet that comes into your system or leaves your system by adding log to each rule. Logging high loads of traffic can be far too much of a workload for ipfw to handle on its own, but many administrators require it for security tracking purposes. Because ipfw sometimes cannot handle the immense logging load, a daemon was developed to unload the logging of ipfw events to another process. Ipfwloggerd is the process that manages logging ipfw events. Logs containing information about traffic that is dropped are stored at /var/log/system.log and can be viewed using the Console application located at /Applications/Utilities. For a more thorough discussion of reviewing logs and the ipfw log, see 5.

Drupal offers a system of distributed authentication that allows people to use the same username and password at multiple sites. The sites communicate with each other to check authentication credentials and to decide whether a username and password combination should be allowed or denied. This is called distributed authentication. If you want your site to have this feature, you need to enable the Drupal module. The Drupal module also lets you run Drupal as a directory server that receives ping notification from other Drupal sites, creating a listing of sites.

You can create the new directory anywhere, but under Ubuntu, the convention is to create it in the /media directory. Therefore, the following command should do the trick (note that you need to use the sudo command, because writing to any directory other than your /home directory requires administrator privileges):

Execution Plan (8.1.7.4) ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=65 Card=58 Bytes=3364) 1 0 INLIST ITERATOR 2 1 TABLE ACCESS (BY INDEX ROWID) OF 'T1' (Cost=65 Card=58 Bytes=3364) 3 2 INDEX (RANGE SCAN) OF 'T1_I1' (NON-UNIQUE) (Cost=9 Card=58) Execution Plan (9.2.0.6 and 10.1.0.4) ---------------------------------------------------------0 SELECT STATEMENT Optimizer=ALL_ROWS (Cost=68 Card=60 Bytes=3480) 1 0 INLIST ITERATOR 2 1 TABLE ACCESS (BY INDEX ROWID) OF 'T1' (Cost=68 Card=60 Bytes=3480) 3 2 INDEX (RANGE SCAN) OF 'T1_I1' (NON-UNIQUE) (Cost=9 Card=60) Sure enough, the cost for the execution plan with the in-list varies between 8i and 9i. This shouldn t really be a surprise; the error in 8i relates directly to the selectivity of the in-list, and only indirectly to the cost. The error has been introduced before we even get to working out the cost. So if you use in-lists with indexes in 8i, the cost for the execution plan may go up, and the optimizer may switch to a different index or even a tablescan when you upgrade to 9i or 10g.

This table is not exhaustive but should serve as an introductory guide. Here are a few notes to help you understand the mappings:

Figure 4-14. The setup for the GridSplitter example Notice that you cannot see all of the text in the second column. Let s add a GridSplitter control to the application so users can resize the two columns to be able to view all the text in both columns. 3. Within the XAML, place the cursor just below the TextBlock definitions you added. Then, in the Visual Studio Toolbox, double-click the GridSplitter control. This will add the xmlns to the System.Windows.Controls assembly, and it will also add the GridSplitter to the application. Then set the Background property of the GridSplitter to LightGray. The source appears as follows: <Grid x:Name="LayoutRoot" Background="White"> <Grid.ColumnDefinitions> <ColumnDefinition Width="150" /> <ColumnDefinition /> </Grid.ColumnDefinitions> <TextBlock Text="Apress, Inc." /> <TextBlock Grid.Column="1" Text="Beginning Silverlight 4: From Novice to Professional" /> <sdk:GridSplitter Name="gridSplitter1" Background="LightGray" /> </Grid>
