I think what unSpawn meant about the "not found" issue was that the file it was looking for was not on your system, therefore it could not check to see if there were any problems with it. Generally speaking, I would assume that was ok. Just because you don't have it on your system doesn't mean it is something you would need. For example, the "telnetd" shows as not found. The program is checking to see if the telnet deamon is infected but has signified that it can't be found or is not installed on your system, so unless you know that you are running a telnet deamon, it's all good.
What unSpawn meant about checking your package manager was something like this. Please not I am unsure what package manager Ubuntu uses (apt-get??). I will presume apt-get however.
If you were unsure about the package named grep in your output (I know, just humour me). You would do
Code:
$su
$apt-get search grep
If you then see a package called grep, you can be sure it is a real program that is used on linux systems for non-malicous reasons and the program chkrootkit will test to see if it is the original version or if it has been changed.
I hope that made at least some sense.
