I've just run rkhunter on one of my Linux boxes. It found an unexpected pair of files: /etc/.java/.systemPrefs/.system.lock /etc/.java/.systemPrefs/.systemRootModFile Both are empty and are timestamped "May 4 11:58" and so are probably connected to an SDK update since I found an archived copy of jdk-6u26- linux-i586.rpm with a timestamp of "May 4 11:59" on the same machine. What is odd is that I installed the same JDK on another machine at the same time and it doesn't have these odd files or the /etc/.java directory in its filing system. So, have any of you seen these files or know why they were created? -- martin@ | Martin Gregorie gregorie. | Essex, UK org |

Such files can be left behind if you abort or crash in mid flight. Did you abort an install? -- Roedy Green Canadian Mind Products http://mindprod.com It should not be considered an error when the user starts something already started or stops something already stopped. This applies to browsers, services, editors... It is inexcusable to punish the user by requiring some elaborate sequence to atone, e.g. open the task editor, find and kill some processes.

I've recently replaced the chkrootkit checker, which seems to have become abandonware some time since 2009, with rkhunter because the chkrootkit FPs were becoming annoying and it turns out that rkhunter is directly supported by RedHat and included in current Fedora distros. While scanning the rkhunter documentation I noticed that by default it ignores /etc/.java and its contents, so evidently its considered benign. So, thanks for your suggestions and comments. Its nice to know that it can safely be ignored. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
