python telnetlib 模块的使用

利用telnetlib模块实现telnet登陆到Huawei OLT，执行相关命令，并把结果保存到config.txt文档。

import telnetlibimport getpassimport sysHOST = "x.x.x.x"user = "test"password = "123456"spacetime = 1tn = telnetlib.Telnet(HOST)tn.read_until("User name:")tn.write(user+"\n")tn.read_until("User password:")tn.write(password+"\n")tn.read_until(">")tn.write("enable\n")tn.read_until("#")#tn.write("display ont info 0 1 0 14\n")tn.write("display ont autofind all\n")tn.read_until(":")tn.write("\n")while spacetime <= 5:    tn.write(" ")    spacetime = spacetime + 1msg=tn.read_until("#")tn.write("quit\n")tn.read_until("(y/n)[n]:")tn.write("y\n")path = r"f:\config.txt"f = file(path,"wb")f.write(msg)f.close()tn.close
