Python与Cisco 的事儿

发布时间:2019-09-23 17:00:03编辑:auto阅读(1702)

       前几天写了一段代码,是用来检查思科设备的端口运行状态的,只是中间有些bug或是存在安全问题,比如密码写在脚本里,对网络不可以达的设备没有进行判断并加以跳过。以下对前两天写的代码进行修改。

    #!/usr/bin/python 
    
    from netmiko import ConnectHandler
    from netmiko.ssh_exception import NetMikoTimeoutException
    import time
    import sys
    import getpass
    
    
    class CiscoNetwork():
            def __init__(self,username,password):
                     self.username = username
                     self.password = password
    
            def CiscoDevice(self,iplist):
    		 self.device={'device_type':'cisco_ios',
                                  'username':self.username,
                                  'password':self.password,
                                  'ip':iplist
                                 }
    		 print('-'*100)
                     print "[+]connect to network device... %s" %(iplist)
                     self.connect = ConnectHandler(**self.device)
    	         self.connect.enable()
    
            def gethostname(self):
                    self.hostname = self.connect.find_prompt()
                    self.hostname = self.hostname.replace("#","")
                    print self.hostname
                 
            def show(self,cmd):
        	         self.output = self.connect.send_command(cmd)
                     for self.line in self.output.split('\n'):
                        if 'line protocol is up'  in self.line:
                            print (self.line)
     
            def close(self):
                    if self.connect is not None:
                           self.connect.disconnect()
                           self.connect = None        
                    
    if __name__ == '__main__':
    	print "[+] This Program is beging done......."
            username = raw_input('Username:')
            password = getpass.getpass() 
    	for iplist in open("/opt/other/ip.txt"):
                    try:
                       switch = CiscoNetwork(username,password)
                       switch.CiscoDevice(iplist)
                       switch.gethostname()
                       switch.show('show int')
                       switch.close()
                    except (EOFError, NetMikoTimeoutException):
                       print ('Can not connect to Device')
