cron captures the output from any program it runs. If there is any output at |
46 |
all, it will mail it to you. In this case, something launched by run-crons is |
47 |
spewing something to STDOUT and you are getting it in your inbox. |
48 |
|

As to what it means, well it looks like garbage. So you will have to run the |
50 |
chkrootkit program yourself and debug how it is going wrong and fix it. This, |
51 |
of course, has nothing whatsoever to do with cron itself. |
52 |
|
53 |
The output looks like standard banner garbage that apps often write to the |
54 |
terminal when launched. I suspect an omitted "> /dev/null" somewhere |
