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()
以上是python使用nmap端口扫描的两种方法的详细内容。更多信息请关注PHP中文网其他相关文章!
