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.

QuickTime 7.3.1 Fixes RTSP Vulnerability

Send Article to a Friend

Apple has released QuickTime 7.3.1, a security update that patches a potentially serious exploit (see "Protect Yourself from the QuickTime RTSP Vulnerability," 2007-09-07). Unlike many recent security issues on the Mac, malicious code that took advantage of the QuickTime RTSP (Real Time Streaming Protocol) vulnerability was active in the wild: a specially crafted Web page could install malicious software on your computer. According to Apple's security release notes, QuickTime 7.3.1 fixes the flaw in RTSP as well as holes in QuickTime's Flash media handler.

Apple recommends the update for all users: it's available via Software Update and in standalone form for Leopard (52.6 MB), Tiger (48.7 MB), Panther (50.9 MB), and Microsoft Windows XP and Vista (20.3 MB).
