Who's There? 2.1 included a number of highly useful new features, along with integration with the DoorStop X Firewall and the latest version of our book Internet Security for Your Macintosh: A Guide for the Rest of Us and its associated blog. Who's There? 2.2 adds support for Leopard (Mac OS X 10.5) and its many new and changed networking services. It also includes access to our Internet security "Top 10" list as well as other minor changes.

Additional Access History filtering features

Who's There's Access History window now provides filtering capabilities beyond those of the three left-side popup menus. Through the built-in filter field in the center of the top part of the window, you can now display only lines containing specific information in any one, or all, of the window's columns. See Figure 1 below.

Search

Who's There? now supports the Mac's standard "Find" commands, letting you search the current display for any specific string, so you can look for a specific IP address, service name, or host name. The next line containing the searched-for information will be highlighted.

Smart scrolling

Who's There? has an improved scrolling algorithm, to better handle situations where you're trying to look at things in the Access History window while additional access attempts are being logged. If you have a line selected, Who's There? will not scroll that line off the screen. Also, if the Access History window isn't sorted by date, Who's There? will not scroll. However if the window is sorted by date (the default), and you don't have a line selected, Who's There? will always display new access attempts as those access attempts come in.

Startup override

When starting Who's There, if you want it to open a log file other than the one it's configured to open, you can override that log file by holding down the option key. Who's There? will then present you with a dialog box where you can choose which log file you wish to open.

Blog and "Top 10" integration

When looking at Who's There's information and advice on a particular service, you can now directly search our security blog, isfym.com and Top 10 list for the latest up-to-date information pertaining to that service.
