Hello All,

 

                I am using Nessus on a windows machine WinXP5.1 Media
Edition, the scans work well on the local machine.  The issue is when I'm
trying to scan other machines on my network.  If my machine is
192.168.1.102, and the other machine I'm trying to scan is 192.168.1.120.  I
enter 192.168.1.120 into the first text box of a new scan, click next ->
Choose Enable all except Dangerous Plugins, click next -> select Scan from
localhost, and sometimes I get "Cannot connect to nessus server!" (restart
service via run:services.msc) LocalHost is 127.0.0.1 loop back port 1241
verified in scan server config. When I do not get this error, I see the host
populate and the progress bar jumps right to 100% and pops up a webpage
saying "No Vulnerabilities"..  It does not seem to actually run, as if it
bailed and spit out a everything is alright report.  Even though the
localmachine is secure it at least brings up some notes.. this on the other
hand has no note or anything.  I have windows firewall open to Nessus, took
it a step further and opened UDP and TCP ports 1241 on the firewall.. I've
also tried modifying my router config to forwarded the port 1241 to the
machine I wish to scan(192.168.1.120)..  Still no luck,  the start time and
stop time of the report that results is only 10 milliseconds apart.  I also
ran a packet sniffer and saw the attempts to the machine I wished to scan
and saw (destination unreachable).  However opening CMD prompt and "ping
192.168.1.120" results in no loss of packets and under 5 millisecond
response times.  If someone has some suggestions or needs more information
it would be much appreciated.

 

Thank you,

 

Jason
