I often find myself opening an SSH session to run the same single command. I have everything setup to login without entering a password (Via SSH Key-Based Auth), so I wondered if there was a way to create a shortcut or a batch file in Windows that would load PuTTY or a similar program, then fire off that command (and likely exit if result is good).
Use the commandline PuTTY version
plink.exe to initate a SSH connection to a host of choice. Use the
-ssh switch to connect with SSH. With the
-m switch you can include a command file:
plink.exe -ssh host1 -m C:\path\to\commands.txt
You can download
plink.exe from here.
Last step would be to create a shortcut including
plink.exe with the desired parameters.
Check out the Plink documentation for other various parameters: Plink.exe documentation
You can use putty configurations to achieve this.
Load putty and configure your session.
Enter the remote command that you'd like to run here:
Then, before clicking "Open", go back to the "Session" tab (at the top), and save your configuration.
Now, create a shortcut to
putty.exe, adding the
-load flag, for example:
%PATH_TO_PUTTY%\putty.exe -load my_config
Now, you can just click on the shortcut and it will load your session, executing your command.
If you're using Windows 10, you might be interested to know that Microsoft reportedly has a beta of OpenSSH (client and server):
[…] go to “Manage Optional Features” then + “Add a feature”. You can then scroll down the list and find the OpenSSH Client (Beta) and OpenSSH Server (Beta) features in Windows. The idea of running another remote service on Windows can be daunting so we do not blame you if you do not want to install the server.
Once installed, you can simply fire up your command line and use the OpenSSH client by typing ssh followed by the command such as
Here is the current (as of November 28, 2017)
sshcommand usage guide we are getting with the Windows OpenSSH Client:
C:\WINDOWS\system32>ssh usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec] [-D [bind_address:]port] [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11] [-i identity_file] [-J [user@]host[:port]] [-L address] [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port] [-Q query_option] [-R address] [-S ctl_path] [-W host:port] [-w local_tun[:remote_tun]] [user@]hostname [command] C:\WINDOWS\system32>
If this works, you should be able to use
ssh like you would on a *Nix:
C:\WINDOWS\system32>ssh user@host "ls -l ~"
Just thought I'd insert the script I made to hopefully save some people hours of syntax and man page research
a) SingleIP, IP Range, or IPList file
b) script name to run on the IP/range (actual unix sh/ksh type script)
c) optionally do nmap scan for port 22 open (i.e. subnet with some non-Linux machines)
-want to avoid IPs putty cannot connect to, avoiding script being able to continue properly
d) optionally run pscp command to autocache the host key (putty does not do this automatically)
This batch assumes:
1. you have the full PuTTY package and SSH key installed in C:\Program Files\PuTTY\
2. batch/scripts/IPlist files installed in C:\Program Files\PuTTY\scripts\
3. The NMAP and PuTTY working directories are in your command path
This is mostly useful for having a single script (such as updating an SSL certificate) across a range of machines
Here is complete batch file:
@ECHO OFF rem You must modify the CACHEKEY and SCRIPT section to reflect your SSH key location set IPFILE=IPList_temp.txt set runagain=n set OPTION=1 set RANGE= set IP= set SCAN=n set KEYCACHE=n :OPTION CLS ECHO (Working directory is set to C:\Program Files\PuTTY\scripts\) ECHO.

This is the final "CMD" which I can just save on my FileServer and create a shortcut on my Desktop.
