需要调用的库：
import telnetlib import datetime import time需要了解的telnetlib函数
telnetlib.Telnet #telnet 连接 telnetlib.read_until #等待字符出现 telnetlib.write #输入命令 telnetlib.read_very_eager #读取页面所以内容完整代码
import telnetlib import datetime import time def login_telnet(Host, username, password, finish, commands): tn = telnetlib.Telnet(Host, port=23, timeout=20) #连接 tn.set_debuglevel(2) tn.read_until(b'Username:') #等待Username出现 tn.write(username.encode('ascii') + b"\n") #输入username tn.read_until(b'Password:') tn.write(password.encode('ascii') + b"\n") tn.read_until(b'') file_object = open(filepath, 'wb') for command in commands: tn.write(command.encode('ascii') + b"\n") time.sleep(2) for i in range(0, 100): #输入100次空格 time.sleep(1) tn.write(b" ") time.sleep(1) result = tn.read_very_eager() file_object.write(result) print('Finish.............') file_object.close() tn.close() if __name__ == '__main__': Host = ''#账号 username = ''#账号 password = ''#密码 finish = ''#等待此字符出现（可不输入） date = datetime.datetime.now()#获取系统当前时间 filepath = '/home/%s.txt'
