python使用nmap端口扫描的两种方法
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 pythonimport nmapimport optparsedef 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> -p <target>') 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</target></target>
Forthly:chmod +x scan_network.py

第二版:支持以逗号分割及以-分割的端口范围
#!/usr/bin/env pythonimport nmapimport optparsedef 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> -p <target>') 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) <p><img src="https://img.php.cn//upload/image/878/600/462/1490162084871472.png" title="python使用nmap端口扫描的两种方法" alt="python使用nmap端口扫描的两种方法" style="max-width:90%" style="max-width:90%"></p></target></target>
