第一版：只支持以逗号分隔的端口，不支持端口范围
firstly：      sudo apt-get install nmap
secondly：pip install python-nmap
thirdly：copy the code bellow to a file like  scan_network.py
#!/usr/bin/env python import nmap import optparse def nmapscan(tgthost,tgtport): nmscan = nmap.portscanner() nmscan.scan(tgthost,tgtport) state=nmscan[tgthost]['tcp'][int(tgtport)]['state'] print ("[*] " + tgthost + " tcp/"+tgtport +" "+state) def main(): parser = optparse.optionparser('usage %prog '+\ '-h <target host> -p <target port>') parser.add_option('-h', dest='tgthost', type='string',\ help='specify target host') parser.add_option('-p', dest='tgtport', type='string',\ help='specify target port[s] separated by comma') (options, args) = parser.parse_args() tgthost = options.tgthost tgtports = str(options.tgtport).split(',') if (tgthost == none) | (tgtports[0] == none): print (parser.usage) exit(0) for tgtport in tgtports: nmapscan(tgthost, tgtport) if name == 'main': main
forthly：chmod +x scan_network.py
fifthly: ./scan_network.py -h 192.168.1.1 -p 22,23
第二版：支持以逗号分割及以-分割的端口范围
#!/usr/bin/env python import nmap import optparse def nmapscan(tgthost,tgtport): nmscan = nmap.portscanner() nmscan.scan(tgthost,tgtport) state=nmscan[tgthost]['tcp'][int(tgtport)]['state'] print ("[*] " + tgthost + " tcp/"+tgtport +" "+state) def main(): parser = optparse.optionparser('usage %prog '+\ '-h <target host> -p <target port>') parser.add_option('-h', dest='tgthost', type='string',\ help='specify target host') parser.add_option('-p', dest='tgtport', type='string',\ help='specify target port[s] separated by comma') (options, args) = parser.parse_args() tgthost = options.tgthost ######this code bellow is to support scan port range like 66-88 tgtports = [] tgtports_cache = str(options.tgtport).split(',') i = int(len(tgtports_cache)) for m in range( 0,i ): tgtports_split = str(tgtports_cache[m]).split('-') if(len(tgtports_split) < 2): tgtports.extend(tgtports_split) #print(tgtports) else: for n in range(int(tgtports_split[0]),int(tgtports_split[1])+1): tgtports.append(str(n)) #print(tgtports) ######above the tgtports are the ports list you want to scann #tgtports = str(options.tgtport).split(',') if (tgthost == none) | (tgtports[0] == none): print (parser.usage) exit(0) for tgtport in tgtports: nmapscan(tgthost, tgtport) if name == 'main': main()
以上就是python使用nmap端口扫描的两种方法的详细内容。
