It seems like straightforward preprocessing string substitution, replace
"default" with "1-1024,blah,blah,blah" but I guess if you don't think it's
useful...

That is exactly the strange part I'm talking about... With nessus set to only
scan port 80 (with nmap, doesn't seem to happen with SYN scan selected
instead) and assume other ports closed, how could the following sequence
occur THREE TIMES for me:

manually check web server, it's running
nessus scan
manually check web server, still running
port 80 doesn't even show up in report, as if port scanner didn't see it.
uncheck "assume other ports closed", press start button again.
nessus scan runs again
manually check web server, still running
port 80 shows up in report this time

I wonder, are there any debugging options that would allow me to easily see
what is going to and from nmap?

Thanks

PS Nmap options are straightforward, SYN scan, Don't randomize, Aggressive.
