Hi there --

Thanks for your reply. I don't have an explanation for it, but when I manually
ran the nessus-update-plugins script and then the nessusd -D command, the
program appeared to run properly. I then ran the two scans
that had previously failed and both appear to be running properly. I'll
continue to monitor the program overnight and see what, if anything, develops. 

One other quick question: I currently do not have nessusd automatically starting
at system boot. I was planning on adding a line to the rc.local file in order to
accomplish this. Do you foresee any problems by my doing so? Thanks.

Starting this past Saturday morning, the

Are you able to run nessus-update-plugins by hand today?

Similarly, the cron jobs failed and the error message that
I encountered in both instances is as follows:

    nessus : Could not open a connection to 127.0.0.1

This suggests that nessusd was down when you tried to run
the scans.

The version of Nessus that I am running is version 2.2.3.

Once you get things working, you may want to upgrade as
2.2.4 offers improvements, especially in terms of SSL reads.

I also tried running the program in daemon mode,
/usr/local/sbin/nessusd -D, but when I did a ps -ef |grep
nessusd check, the program did not appear to be running. 

nessusd.messages should have information explaining why the
daemon shut down and possibly why it won't start. Do you see
anything in there that might explain the problem? If not,
try using a tool such as strace to trace nessusd's execution
as it starts up and study the last few lines.
