1）问题描述

　　在windows下会抛出以下异常。

Traceback (most recent call last):    File "ftplogin_file.py", line 111, in <module>      main()    File "ftplogin_file.py", line 109, in main      ftpLogin(filepath)    File "ftplogin_file.py", line 77, in ftpLogin      if nmapScan(ip,"21") == True:    File "ftplogin_file.py", line 8, in nmapScan      nmScan = nmap.PortScanner()    File "C:\Python27\lib\site-packages\nmap\nmap.py", line 144, in __init__      raise PortScannerError(‘nmap program was not found in path. PATH is : {0}‘.f  ormat(os.getenv(‘PATH‘)))  nmap.nmap.PortScannerError: ‘nmap program was not found in path. PATH is : C:\\W  INDOWS\\system32;C:\\WINDOWS;C:\\WINDOWS\\System32\\Wbem;C:\\Python27;D:\\WPS Of  fice\\9.1.0.4468\\office6;C:\\Program Files\\Microsoft Visual Studio\\Common\\To  ols\\WinNT;C:\\Program Files\\Microsoft Visual Studio\\Common\\MSDev98\\Bin;C:\\  Program Files\\Microsoft Visual Studio\\Common\\Tools;C:\\Program Files\\Microso  ft Visual Studio\\VC98\\bin‘  

抛出异常的地方

nmScan = nmap.PortScanner()

2）解决方案

　　抛出异常的原因是因为没有指定nmap的执行路径所致,在windows下需要手动指定nmap的执行路径。

修改后

nmScan = nmap.PortScanner(nmap_search_path=(‘nmap‘,r"H:\Nmap\nmap.exe"))

3）修改后的完整代码

import nmapimport optparsedef nmapScan(tgtHost,tgtPort):    nmScan = nmap.PortScanner(nmap_search_path=(‘nmap‘,r"H:\Nmap\nmap.exe"))    nmScan.scan(tgtHost,tgtPort)    state = nmScan[tgtHost][‘tcp‘][int(tgtPort)][‘state‘]    print ‘[*]‘ + tgtHost + ‘ tcp/‘ + tgtPort + ‘ ‘ + statedef 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()

4）再次运行,运行结果如下

D:\Python-Nmap>python2 test.py -H 192.168.1.44 -p 21,22,1720[*]192.168.1.44 tcp/21 closed[*]192.168.1.44 tcp/22 closed[*]192.168.1.44 tcp/1720 closed
