Run mDNSNetMonitor in a terminal window. # When you have enough traffic, type Ctrl-C and save the content of the terminal window to disk. # Alternatively, you can use "mDNSNetMonitor > logfile" to write the text directly to a file. # You now have a UTF-8 text file. # 2. Open the UTF-8 text file using BBEdit or some other text editor. # (These instructions are for BBEdit, which I highly recommend you use when doing this.) # 3. Make sure BBEdit correctly interprets the file as UTF-8. # Either set your "Text Files Opening" preference to "UTF-8 no BOM", and drop the file onto BBEdit, # or manually open the File using "File -> Open" and make sure the "Read As" setting is set to "UTF-8 no BOM" # Check in the document pulldown menu in the window toolbar to make sure that it says "Encoding: UTF-8 no BOM" # 4. Use "Tools -> Convert to ASCII" to replace all special characters with their seven-bit ascii equivalents. # (e.g. curly quotes are converted to straight quotes) # 5. Do a grep search and replace. (Cmd-F; make sure Grep checkbox is turned on.) # Enter this search text : ^(.................\(................\S*) (.* -> .*)$ # Enter this replacement text: \1-\2 # Click "Replace All" # Press Cmd-Opt-= repeatedly until there are no more instances to be replaced. # You now have text file with all spaces in names changed to hyphens # 6. Save the new file. You can save it as "UTF-8 no BOM", or as "Mac Roman". It really doesn't matter which -- # the file now contains only seven-bit ascii, so it's all the same no matter how you save it. # 7. Run "parselog.py fname" # 8. Open the resulting fname.pdf file with a PDF viewer like Preview on OS X # # Key to what you see: # Time is on the horizontal axis # Individual machines are shown on the vertical axis # Filled red circle: Normal query Hollow red circle: Query requesting unicast reply # Filled orange circle: Probe (service starting) Hollow orange circle: First probe (requesting unicast reply) # Filled green circle: Normal answer Hollow green circle: Goodbye message (record going away) # Hollow blue circle: Legacy query (from old client) from CoreGraphics import * import math # for pi import string import sys, os import re def parselog(inFile): f = open(inFile) hunt = 'getTime' ipList = {} querySource = {} plotPoints = [] maxTime=0 minTime = 36*60*60 spaceExp = re.compile(r'\s+') print "Reading " + inFile while 1: lines = f.readlines(100000) if not lines: break for line in lines: if (hunt == 'skip'): if (line == '\n' or line == '\r' or line ==''): hunt = 'getTime' # else: # msg = ("skipped" , line) # print msg elif (hunt == 'getTime'): if (line == "^C\n" ): break time = line.split(' ')[0].split(':') if (len(time)<3): #print "bad time, skipping",time hunt = 'skip' else: hunt = 'getIP' #print (("getTime:%s" % (line)), time) elif (hunt == 'getIP'): ip = line.split(' ',1) ip = ip[0] secs=0 for t in time: secs = secs*60 +float(t) if (secs>maxTime): maxTime=secs if (secs" symbol and following rdata #print qaList if (qaList[0] == ip): if (qaList[1] == '(QU)' or qaList[1] == '(LQ)' or qaList[1] == '(PU)'): plotPoints.append([secs, ipList[ip][0], (qaList[1])[1:-1]]) elif (qaList[1] == '(QM)'): plotPoints.append([secs, ipList[ip][0], (qaList[1])[1:-1]]) querySource[qaList[3]] = len(plotPoints)-1 elif (qaList[1] == '(PM)'): plotPoints.append([secs, ipList[ip][0], (qaList[1])[1:-1]]) querySource[qaList[4]] = len(plotPoints)-1 elif (qaList[1] == '(AN)' or qaList[1] == '(AN+)' or qaList[1] == '(DE)'): plotPoints.append([secs, ipList[ip][0], (qaList[1])[1:-1]]) try: theQuery = querySource[qaList[4]] theDelta = secs -
