The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Hello srividyarao,
which version of perl you are using? on Perl 5.8 , you can select the module through ppm UI.
or
on command prompt try: ppm install Net::SSH::Perl

Net::SSH::PERL is a way to access SSH via a perl script.

ssh has the ability to execute a program on the remote machine if you supply that program name on the command line.

now if ALL you are trying to do is execute the remote command on the remote server via a script, skip PERL, its overkill for this.


just use a simple shell script with a carefully crafted ssh command line.

read man ssh for details.

now nothing is saying that the program on  the remote server shouldnt be a perl script, it certainly can, but unless Im missing something I think perl is overkill for what you have asked.

something as simple as

#!/bin/sh
ssh user@host command

now this assumes that you are logging in via authkeys and NOT via keyboard passwords.

it will work with keyboard, but its not something you could turn into a cron job

research logging in via keys separately
