Micah, It looks like your scan has not finished running. It is in the middle of NSE scanning (as a result of the -sV in your command line, it is running all NSE scripts in the "version" category). You should make sure Nmap is done scanning before you try to compare results with Ndiff. On the other hand, I see a "Segmentation fault" error just before the Python traceback. It *might* be possible that Nmap is crashing, leaving an unfinished XML file. Is there any way you can manually run your scan with debugging output to determine what if anything might be causing that crash?

Hi, I'm running nmap (7.01-2 from debian) scans out of cron once a day and trying to ndiff the results, but each time I'm getting the same python traceback and error. I'm basically doing this: /usr/bin/nmap -v --open -sV --datadir /home/nmap/scans $TARGETS -oA scan-$date > /dev/null and then comparing the scans like this: /usr/bin/ndiff scan-prev.xml scan-$date.xml > diff-$date the error I get is this: Segmentation fault Traceback (most recent call last): File "/usr/bin/ndiff", line 85, in <module> sys.exit(ndiff.main()) File "/usr/lib/python2.7/dist-packages/ndiff.py", line 1503, in main scan_b.load_from_file(filename_b) File "/usr/lib/python2.7/dist-packages/ndiff.py", line 74, in load_from_file self.load(f) File "/usr/lib/python2.7/dist-packages/ndiff.py", line 68, in load parser.parse(f) File "/usr/lib/python2.7/xml/sax/expatreader.py", line 110, in parse xmlreader.IncrementalParser.parse(self, source) File "/usr/lib/python2.7/xml/sax/xmlreader.py", line 125, in parse self.close() File "/usr/lib/python2.7/xml/sax/expatreader.py", line 225, in close self.feed("", isFinal = 1) File "/usr/lib/python2.7/xml/sax/expatreader.py", line 217, in feed self._err_handler.fatalError(exc) File "/usr/lib/python2.7/xml/sax/handler.py", line 38, in fatalError raise exception xml.sax._exceptions.SAXParseException: scan-2016-02-01.xml:2201:0: no element found That file (scan-2016-02-01.xml) looks like normal xml, if I run an xml validator on it, I'm told: Error: Document ends too soon in unnamed entity at line 2200 char 43 of file, if I go to that line in the file, I find this: ... <taskend task="Connect Scan" time="1454367205" extrainfo="39000 total ports"/> <taskbegin task="Service scan" time="1454367205"/> <taskprogress task="Service scan" time="1454367237" percent="28.40" remaining="81" etc="1454367318"/> <taskprogress task="Service scan" time="1454367273" percent="52.67" remaining="62" etc="1454367334"/> <taskprogress task="Service scan" time="1454367303" percent="71.60" remaining="39" etc="1454367342"/> <taskend task="Service scan" time="1454367460" extrainfo="243 services on 39 hosts"/> <taskbegin task="NSE" time="1454367460"/> line 2200 is the last line above, the last character on the line ('>') is character number 41 thanks for any suggestions or help! micah _______________________________________________ Sent through the dev mailing list https://nmap.org/mailman/listinfo/dev Archived at http://seclists.org/nmap-dev/
