Mac OS X Server Ships -- Apple last week shipped Mac OS X Server, a new Unix-based operating system for high-end server use. Formerly codenamed Rhapsody, Mac OS X Server features the popular Apache Web server, Apple's WebObjects, the capability to boot newer Macintosh models remotely via NetBoot, a high-performance Java virtual machine, network services such as DNS and Apple File Protocol, Web-based administration, and a consistent Mac-like user interface. (See "New iMacs, New G3s, and Mac OS X Server" in TidBITS-462 for more information.) Mac OS X Server runs BSD Unix 4.4 on top of the Mach 2.5 microkernel (which together offer preemptive multitasking and protected memory), plus features application technologies originally acquired from NeXT. Mac OS X Server reportedly includes the Blue Box application layer, enabling Mac OS X Server to run standard Mac OS applications. By all reports, the Blue Box isn't intended to allow Mac OS X Server to act as a workstation or to run current Mac OS server software. Developer support for Mac OS X Server is growing; several companies have already announced plans for Mac OS X Server, and more are sure to follow. Apple has priced Mac OS X Server aggressively at $499, with an unlimited client license; Apple is also selling 400 MHz G3-based servers with Mac OS X Server pre-installed starting at $4,999 (which Apple says is the fastest Apache server platform available for under $5000).

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.
