AirPort 1.2 Update Available -- Apple Computer has released AirPort 1.2, the latest version of its wireless networking software for configuring AirPort Base Stations and enabling any AirPort-equipped Mac to act as a software base station. AirPort 1.2's base station software ships with a default configuration that disables AirPort-to-Ethernet bridging, does not assign DHCP addresses, or share a single IP address on an Ethernet network via Network Address Translation (NAT), but all these services can still be enabled from the AirPort Admin utility. We know that's a mouthful: in a nutshell, these changes make it easier to introduce AirPort base stations into existing networks without disrupting services. AirPort 1.2 also supports closed networks in which the name of the AirPort network is hidden; this provides an additional level of obscurity in that users must know the exact name of the AirPort network to connect to it. Apple also says the AirPort 1.2 software improves stability and performance. The software is a 4.5 MB download and requires at least Mac OS 8.6 or higher (with Mac OS 9.0.4 recommended). Apple has also released a PDF document called Designing AirPort Networks and is conducting an online survey of AirPort Base Station users so Apple can prioritize future development. [GD]
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
