Problems and solutions in the operation of Windows Python-nmap

1) Description of the problem

The following exception is thrown under Windows.

Traceback (most recent): File"ftplogin_file.py", line 111,inch<module>Main () File"ftplogin_file.py", line 109,inchmain FTPLogin (filepath) File"ftplogin_file.py", Line 77,inchFTPLoginifNmapscan (IP," +") ==True:file"ftplogin_file.py", line 8,inchNmapscan Nmscan=Nmap. Portscanner () File"C:\Python27\lib\site-packages\nmap\nmap.py", line 144,inch __init__      RaisePortscannererror ('Nmap program is not a found in path. PATH is: {0}'. F ormat (Os.getenv ('PATH')) Nmap.nmap.PortScannerError:'Nmap program is not a found in path.

Where the exception is thrown

Nmscan = Nmap. Portscanner ()

2) Solutions

The exception is thrown because the execution path of NMAP is not specified, and the execution path of NMAP needs to be specified manually under Windows.

After modification

Nmscan = Nmap. Portscanner (nmap_search_path= (' Nmap ', r "H:\Nmap\nmap.exe"))

3) The complete code after the modification

ImportNmapImportOptparsedefNmapscan (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 +' '+ StatedefMain (): Parser= Optparse.

4) run again and the results are as follows

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
