Angry IP Scanner broken in Mac OS 10.5.5 (and later)
In an earlier “Confessions” post I’d mentioned Angry IP Scanner, a terrific little app that does IP address and port scans. What I didn’t mention, because I didn’t realize it at the time, is that it doesn’t work in Mac OS X 10.5.5 and later (including the current 10.5.6) due to a Java incompatibility. By Googling the Console error messages (always the best way of tracking down a strange problem) I found this post in the Angry IP Scanner section of the SourceForge forum:
In Terminal:
$ cd /Applications/Angry\ IP\ Scanner.app/Contents/MacOS/
$ rm /Applications/Angry\ IP\ Scanner.app/Contents/MacOS/ipscan
$ cp /System/Library/Frameworks/JavaVM.framework/Resources/MacOS/JavaApplicationStub ipscan
This worked as advertised and Angry IP Scanner now launches and runs again without error.
