I have a scenario where I need to run a linux shell command frequently (with different filenames) from windows. I am using PuTTY and WinSCP to do that (requires login name and password). The file is copied to a predefined folder in the linux machine through WinSCP and then the command is run from PuTTY. Is there a way by which I can automate this through a program. Ideally I would like to right click the file from windows and issue the command which would copy the file to remote machine and run the predefined command (in PuTTy) with the filename as argument.
Putty usually comes with the "plink" utility.
This is essentially the "ssh" command line command implemented as a windows .exe.
It pretty well documented in the putty manual under "Using the command line tool plink".
You just need to wrap a command like:
plink root#myserver /etc/backups/do-backup.sh
in a .bat script.
You can also use common shell constructs, like semicolons to execute multiple commands. e.g:
plink read#myhost ls -lrt /home/read/files;/etc/backups/do-backup.sh
There could be security issues with common methods for auto-login.
One of the most easiest ways is documented below:
Running Putty from the Windows Command Line
And as for the part the executes the command
In putty UI, Connection>SSH> there's a field for remote command.
4.17 The SSH panel
The SSH panel allows you to configure
options that only apply to SSH
sessions.
4.17.1 Executing a specific command on the server
In SSH, you don't have to run a
general shell session on the server.
Instead, you can choose to run a
single specific command (such as a
mail user agent, for example). If you
want to do this, enter the command in
the "Remote command" box.
http://the.earth.li/~sgtatham/putty/0.53/htmldoc/Chapter4.html
in short, your answers might just as well be similar to the text below:
let Putty run command in remote server
You can write a TCL script and establish SSH session to that Linux machine and issue commands automatically. Check http://wiki.tcl.tk/11542 for a short tutorial.
You can create a putty session, and auto load the script on the server, when starting the session:
putty -load "sessionName"
At remote command, point to the remote script.
You can do both tasks (the upload and the command execution) using WinSCP. Use WinSCP script like:
option batch abort
option confirm off
open your_session
put %1%
call script.sh
exit
Reference for the call command:
https://winscp.net/eng/docs/scriptcommand_call
Reference for the %1% syntax:
https://winscp.net/eng/docs/scripting#syntax
You can then run the script like:
winscp.exe /console /script=script_path\upload.txt /parameter file_to_upload.dat
Actually, you can put a shortcut to the above command to the Windows Explorer's Send To menu, so that you can then just right-click any file and go to the Send To > Upload using WinSCP and Execute Remote Command (=name of the shortcut).
For that, go to the folder %USERPROFILE%\SendTo and create a shortcut with the following target:
winscp_path\winscp.exe /console /script=script_path\upload.txt /parameter %1
See Creating entry in Explorer's "Send To" menu.
Here is a totally out of the box solution.
Install AutoHotKey (ahk)
Map the script to a key (e.g. F9)
In the ahk script,
a) Ftp the commands (.ksh) file to the linux machine
b) Use plink like below. Plink should be installed if you have putty.
plink sessionname -l username -pw password test.ksh
or
plink -ssh example.com -l username -pw password test.ksh
All the steps will be performed in sequence whenever you press F9 in windows.
Code:
using System;
using System.Diagnostics;
namespace playSound
{
class Program
{
public static void Main(string[] args)
{
Console.WriteLine(args[0]);
Process amixerMediaProcess = new Process();
amixerMediaProcess.StartInfo.CreateNoWindow = false;
amixerMediaProcess.StartInfo.UseShellExecute = false;
amixerMediaProcess.StartInfo.ErrorDialog = false;
amixerMediaProcess.StartInfo.RedirectStandardOutput = false;
amixerMediaProcess.StartInfo.RedirectStandardInput = false;
amixerMediaProcess.StartInfo.RedirectStandardError = false;
amixerMediaProcess.EnableRaisingEvents = true;
amixerMediaProcess.StartInfo.Arguments = string.Format("{0}","-ssh username#"+args[0]+" -pw password -m commands.txt");
amixerMediaProcess.StartInfo.FileName = "plink.exe";
amixerMediaProcess.Start();
Console.Write("Presskey to continue . . . ");
Console.ReadKey(true);
}
}
}

Try MtPutty,
you can automate the ssh login in it. Its a great tool especially if you need to login to multiple servers many times. Try it here
Another tool worth trying is TeraTerm. Its really easy to use for the ssh automation stuff. You can get it here. But my favorite one is always MtPutty.
In case you are using Key based authentication, using saved Putty session seems to work great, for example to run a shell script on a remote server(In my case an ec2).Saved configuration will take care of authentication.
C:\Users> plink saved_putty_session_name path_to_shell_file/filename.sh
Please remember if you save your session with name like(user#hostname), this command would not work as it will be treated as part of the remote command.

I am trying to run sesu command in Unix server from Python with the help of Paramiko exec_command. However when I am running this command exec_command('sesu test'), I am getting
sh: sesu: not found
When I am running simple ls command it giving me desired output. Only with sesu command it is not working fine.
This is how my code looks like:
import paramiko
host = host
username = username
password = password
port = port
ssh=paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(ip,port,username,password)
stdin,stdout,stderr=ssh.exec_command('sesu test')
stdin.write('Password')
stdin.flush()
outlines=stdout.readlines()
resp=''.join(outlines)
print(resp)
The SSHClient.exec_command by default does not run shell in "login" mode and does not allocate a pseudo terminal for the session. As a consequence a different set of startup scripts is (might be) sourced, than in your regular interactive SSH session (particularly for non-interactive sessions, .bash_profile is not sourced). And/or different branches in the scripts are taken, based on an absence/presence of TERM environment variable.
Possible solutions (in preference order):
Fix the command not to rely on a specific environment. Use a full path to sesu in the command. E.g.:
/bin/sesu test
If you do not know the full path, on common *nix systems, you can use which sesu command in your interactive SSH session.
Fix your startup scripts to set the PATH the same for both interactive and non-interactive sessions.
Try running the script explicitly via login shell (use --login switch with common *nix shells):
bash --login -c "sesu test"
If the command itself relies on a specific environment setup and you cannot fix the startup scripts, you can change the environment in the command itself. Syntax for that depends on the remote system and/or the shell. In common *nix systems, this works:
PATH="$PATH;/path/to/sesu" && sesu test
Another (not recommended) approach is to force the pseudo terminal allocation for the "exec" channel using the get_pty parameter:
stdin,stdout,stderr = ssh.exec_command('sesu test', get_pty=True)
Using the pseudo terminal to automate a command execution can bring you nasty side effects. See for example Is there a simple way to get rid of junk values that come when you SSH using Python's Paramiko library and fetch output from CLI of a remote machine?
You may have a similar problem with LD_LIBRARY_PATH and locating shared objects.

Is there any way to save the PuTTY output to a file using the command line? I know this is easily done using the GUI but in my case it has to be done automatically.
What I'm working on:
User clicks batch file -> starts PuTTY, automatically connects to my device over SSH and runs a bunch of commands -> PuTTY should save the output to a file.
This can be done by changing registry settings.
Entry point for you is to check what and where is stored for putty:
run regedit and go to HKEY_CURRENT_USER\Software\SimonTatham\PuTTY
you can export settings to file by:
regedit /e "%userprofile%\desktop\putty-registry.reg" HKEY_CURRENT_USER\Software\Simontatham
From here,edit putty-registry.reg to your needs and import on user machine.
I want to automate the export process which I take using expdp command in Oracle.
Following is the contents of batch file I have created to open PuTTY.
#echo off
"C:\Program Files\PuTTY\plink.exe" username#Ip_Addr -pw password -m Open_Putty.txt`
Following is the contents of Open_Putty.txt to execute different commands.
echo $ORACLE_SID;
Read oraenv;
But after opening Open_Putty.bat it disappears without showing any output.
Please help me with this. I want to set oraenv and run some more commands to take the backup.
It's unlikely that plink.exe disappears without showing any output. I assume you execute the batch file from a Windows Explorer or other GUI application, so the Plink console window disappears once Plink finishes (possibly with error) and you cannot read the output (error).
Make sure you execute plink.exe from a console window (typically a cmd.exe) or add pause command to the end of the batch.
Make sure Plink can find the script file (Open_Putty.txt). As you do not specify a path to the file, it has to be located in your current working directory. Safer is to use a full path to the script file:
"C:\Program Files\PuTTY\plink.exe" username#Ip_Addr -pw password -m "C:\path\Open_Putty.txt"
The backtick symbol at the end of the command should probably not be there.
The name "Open PuTTY" is bit confusing. You are not using PuTTY at all. And even if you refer to Plink by "PuTTY", your script file (Open_Putty.txt) is not opening PuTTY nor Plink. It's executing remote commands. So you should better name it export.txt or similar.
I need to execute the command :- Powermt display dev = all in the command prompt of a remote computer. How do I do that ?
If you have PowerShell 2.0 or higher on both computers and can enable remoting on the remote computer by execute Enable-PSRemoting -Force, then from an elevated/admin PowerShell prompt you can run:
Invoke-Command -ComputerName remotepcname -ScriptBlock { <commands to execute remotely> }
This will execute the commands remotely and return the results to the local computer.
Here's another alternative to try where psexec and powershell fail. It's convoluted and hackish, but at least it's something else to try. :)
Firstly, share a folder on your own machine. Make sure an account with admin rights on the remote machine has write access to this share you create. Then execute the following:
wmic /node:remoteComputerAddr /user:adminOnRemoteComputer /password:adminPassword process call create "cmd.exe /c powermt display dev=all >>\\localComputerAddr\shareName\results.txt"
#type "c:\local\path\to\share\results.txt"
Unfortunately, wmic doesn't show you the output of the process it creates. That's why you enable a share on your local workstation, then redirect the output from the remote command to your share.

I need to start a document on a remote computer instead of an executable file, using PSExec.
I tried to provide the file name of a jpg file to psexec associated with the -c command to copy the file, but the message returned for documents (and not executables) is always "The system cannot find the file specified."
Anyone any ideas what the command-line for psexec should be?
Try to use the command:
cmd.exe /c START c:\path\to\document.jpg
Document must be on the remote computer, so you have to copy it there by other command before calling psexec.
Pick a program on that other machine that can show the JPEG and execute that, passing to it the path and name to the file you want to show.
As you've noticed, file associations doesn't work with remote execution like that, so you need to invoke the correct program instead.
In order to open a remote program and not only activate its process you have to use PSEXEC
with the -i (Interactive Mode) and MUST define the session number.
For example:
Usually on a Win7 host:
Console = Session 0
System = Session 1
User = Session 2
In order to activate and open notepad.exe on this remote Win 7 host use the following syntax:
psexec -i 2 \\ComputerName -u User -p Pass notepad.exe

This is the way that worked for me:
I've logged on to the via RDP:
I've copied a picture to the to "C:\Users<MyUserName>\Pictures\smiley.png"
I've opened a new powershell-window, typed "tasklist" and found out my windows session id (I simple took the highest session id I've found)
Back on my own PC:
I've downloaded PSTOOLS from https://download.sysinternals.com/files/PSTools.zip
I've unpacked PSTOOLS and placed it in "C:\Program Files\PSTools"
I've opened a new powershell-window and typed: cd "C:\Program Files\PSTools"
Finally i've started the remote PAINT with:
"C:\Program Files\PSTools\psexec" -s -i 4 "\\[RemoteComputerName]" "C:\Windows\system32\mspaint.exe" "C:\Users\[MyUserName]\Pictures\smiley.png"
P.S.: Don't forget to replace [RemoteComputerName] and [MyUserName]
