Three programming codes for autoTelnet

In some programming applications, we often involve the content related to autoTelnet. Here we will discuss the implementation of autoTelnet. We can implement this file in three ways. For details about the code implementation, refer to the following section.

I. Shell implementation, file name: autoTelnet. sh, the Code is as follows:

(sleep 1;echo "root";sleep 1;echo "123456";sleep 1;echo "en";sleep 1;echo "1qazse4";sleep 1;echo "conf t";sleep 1;echo "int fa0/1";sleep 1;echo "switchport mode multi";sleep 1;echo "end";sleep 1;echo "exit") | Telnet 10.32.17.10 

Ii. Verify CT. The file name is autoTelnet. exp. The Code is as follows:

 
 

  
  
#!/usr/bin/expect   
  
  
set timeout 100   
  
  
set TERM xterm   
  
  
set SERVER "10.32.17.10"   
  
  
set USER "root"   
  
  
set PASSWD "123456"   
  
  
spawn Telnet   
  
  
expect "Telnet> "   
  
  
send "open $SERVERr"   
  
  
expect "Username:"   
  
  
send "$USERr"   
  
  
expect "Password:"   
  
  
send "$PASSWDr"   
  
  
expect "longjiang-zero>"   
  
  
send "enr"   
  
  
expect "Password:"   
  
  
send "$PASSWDr"   
  
  
expect "longjiang-zero#"   
  
  
send "conf tr"   
  
  
expect "longjiang-zero(config)#"   
  
  
send "int fa0/1r"   
  
  
expect "longjiang-zero(config-if)#"   
  
  
send "switchport mode multir"   
  
  
expect "longjiang-zero(config-if)#"   
  
  
send "endr"   
  
  
expect "longjiang-zero#"   
  
  
send "exitr"   
  
  
interact  
 
 

Iii. Python implementation. File Name: autoTelnet. py. The Code is as follows:

 
 

  
  
#!/usr/bin/python   
  
  
import Telnetlib   
  
  
host = ''10.32.17.10''   
  
  
user = ''root''   
  
  
password = ''123456''   
  
  
commands = [''en'',password,''conf t'',''int fa0/1'',''switchport mode multi'',''end'']   
  
  
tn = Telnetlib.Telnet(host)   
  
  
tn.read_until("Username:")   
  
  
tn.write(user + "n")   
  
  
tn.read_until("Password:")   
  
  
tn.write(password + "n")   
  
  
for command in commands:   
  
  
tn.write(command+''n'')   
  
  
tn.write("exitn")   
  
  
print tn.read_all()   
  
  
print ''Finish!''
