Hi Experts,

     I am trying to run a script on a Linux server from windows.  I don't have rsh service available.  What's the most simple way to do this??  If possible, here's what i want:

a DOS batch file on windows that i just double click and then it will run the script on the linux server.

Thx a lot!!!

Install a service in /etc/inetd.conf,  f.i.
<name>      stream  tcp     nowait  <username>    /usr/sbin/tcpd  /bin/bash -c /sbin/<yourscript>

Assign a port/protocol in /etc/services:
<name>      <portnumber>/tcp

restart inetd: killall -HUP inetd

Now all you have to do is to make a tcp connection to that portnumber. This can be done f.i. by your browser or telnet.

Hi bobqunzel,

     I don't have administrator rights.  Is there some other way to do this?  All I have is ftp from the windows command prompt, telnet and ssh.  Is there a way to write a ssh script or telnet script?  I am not too famaliar with this, but I cannot use anything that requires administrative rights to setup.

Thanks!

You can absolutely write a script via ssh, assuming you have an acccount on the Linux server (doesn't have to be root, by the way).

There are two ways to do this, based upon the complexity of the script that you wish to write.  The best way is as such:

Log on to the Linux server via SSH.  This doesn't require administrative priviledges on either system, just a simple login.  Using your favorite editor, write your script.  If the script is already written, you can use FTP or SFTP to copy the file.

Let's assume that you have Putty, plink, pscp, and puttygen on the Windows system:
(You can download all of these tools here):
http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Assuming you need to write the script:

1.  In Putty, type the IP address or hostname of the Linux server, and select SSH.  Click on "Open"

2.  Log into the Linux server with your username and password.

3.  Type your script in your favorite editor.

Assuming you need to copy the script over from the Windows system:

1.  Start -> Run -> "cmd" <Enter>
2.  c:\> ftp <IP Address of Linux Server>  and login
3.  ftp>  put <local file>

Now that the script is on the system, we need to set up the DOS script.

There are two ways to do this; using a password, and using a key (recommended)


Once the script is in your home directory, you can use putty in a DOS batch script to execute the script like so:

First, fire up puttygen.  Create an SSH2 RSA key.  Save it somewhere that is easy for your batch script to find.
You'll notice a window at the top that says "Public key for pasting into OpenSSH".  Copy that to the linux server as this filename:
/home/<your_directory>/.ssh/authorized_keys

This allows you to connect to the server without a password.

Next, write your DOS batch script.  It will look like this:

@echo off
...\plink.exe --ssh -i D:\PATH\TO\SSH\KEY  root@HOST  ./my_script


This should get you started.  Good luck!

Hi

Is plink and puttygen separate programs from putty?

and from
...\plink.exe --ssh -i D:\PATH\TO\SSH\KEY  root@HOST  ./my_script
i am not the root account, can i do username@HOST instead??

Thanks!!

Sorry about the root, yes, you can use username@HOST.

Also, if you click on the link in my last post, you will find plink and puttygen (which are separate programs from putty).

Cheers,
