SSH Remote Tool

SSH Automatic Command

I am showing how to use some third party tool to run SSH to remote connection and run some some command.

TeraTerm

SSH Connection

  • Create ttl file
    The ttl file is macro script, that TeraTerm can be able to load. In this file you have to add the command you want to execute after login ssh.

Below this terateam script just use SSH to make connection. User no need to enter account and password. It will just automatic open SSH connection then you can type command

5
timeout=10
pause 5

connect '192.168.1.254 /ssh /auth=password /user=root /passwd=1234567890 /nosecuritywarning'

If you want to run SSH command you can refer below example this will run command and close terateam.

pause 2
sendln 'cat /etc/arcwrt_release'

;sendln 'tr69_trigger setvalue Device.ManagementServer.EnableCWMP=1'
pause 4

;sendln 'tr69_trigger setvalue Device.ManagementServer.URL="http://172.21.201.112:8080/acs"'
;pause 5

If you want to check your ttl script work or not, just open terateam control>macro and load the file will see if script work or not.

  • Create a bat
    If you want to automatic run the script, you have to use bat file to open terateam and load the macroscript like below. After you add .bat file then it will automatic load the ttl file.

@echo off
cd c:\
cd C:\Program Files (x86)\teraterm5
REM Your ttl file full location
ttermpro.exe /m="C:\Users\chenchih_lee\Desktop\ssh_autoscript\SSH\SSH_Host.ttl"

Note: TeraTeam is a window third party tool for SSH/TELNET/Com port tool so it will only be running on Window OS.

PLINK

Plink download is a tool just like putty, which allow to use cli command to do ssh connection. If you want to do SSH automation. Let me show plink related basic command:

Make a basic ssh remote connection

Syntax:

plink -ssh -pw <password> admin@192.168.0.1 "command"
ex: plink -ssh user1@10.10.1.11 -pw password@123 (hostname; date)

Note:

  • If you see Access granted, you have to enter to login, you can use: -no-antispoof
  • The -m option tells Plink to read the entire command sequence from the file.
  • batch means it will run as silently as possible, so it won’t even ask you to accept the fingerprint. This will never work on your first connection. Without -batch you will see a “press enter to start the session” prompt, however, that goes away with -no-antispoof.

Use one line command

  • one command with grep
1
plink -ssh -pw 123456 test@192.168.1.106 "cat /etc/arcwrt_release | grep 'ARCWRT_PROJECT_NUMBER'"

or

1
plink -ssh -pw 123456 test@192.168.1.106 "grep 'ARCWRT_PROJECT_NUMBER' /etc/arcwrt_release"
  • Multiply command
1
plink -ssh -pw 123456 test@192.168.1.106 "ls;echo Hello World;ls"
  • Advance Filter command
1
plink -ssh -pw <password> root@<IP> "grep 'ARCWRT_PROJECT_NUMBER' /etc/arcwrt_release | cut -d '\"' -f 2; tr69_trigger getvalue Device.ManagementServer.URL"

Run Command by variable or file

You can either add your command into a file or as variable when run ssh will execute it.

File( basic):

  • Add command into cli.txt file
1
2
3
ls
pwd
cat /etc/arcwrt_release
  • Create bat shell script
    Put your command into file, it will read it and run it.

File(filter command)

  • Add command into command_1.txt file

#grep ARCWRT_PROJECT_NUMBER /etc/arcwrt_release | cut -d '"' -f 2
