IPRange ssh scan python

Question

是否有可能使我的＆＃34; raw_input - rmip ＆＃34;接受并转换iprange（192.168.1.1/28），然后扫描所有iprange和端口？我尝试用IPset模块做到这一点，但我有一些错误。

 #!/usr/bin/env python
    import socket, subprocess,sys
    import os 
    from netaddr import *

    subprocess.call('clear',shell=True)
    rmip = raw_input("\t enter your ip address: ")
    r1 = int(raw_input("\t enter start port :\t"))
    r2 = int(raw_input("\t enter end port :\t"))

for ips in IPSet([rmip]):
    try:
        for port in range(r1,r2):       
                    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
                    socket.setdefaulttimeout(1)
                    result = sock.connect_ex((ips, port))
                    if result == 0:
                        print "  [-] Port Open: --->\t", port
                    sock.close()
    except KeyboardInterrupt:
            print "You stop this "
            sys.exit()
    except socket.gaierror:
            print "Hostname could not be resolved"
            sys.exit()
    except socket.error:
            print "could not connect to server"
            sys.exit()

输出：

     enter your ip address: 129.1.1.1/24
     enter start port : 1
     enter end port :   4000
