Communication between Windows and Linux via Perl

zhonghua has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I want to use a script on Windows to execute some commands on Linux, then return the command results.

I put the Linux RSA identity file "id_rsa" under C: direcoty. And the following is my code:

---------------------clip-------------------------

#!/usr/bin/perl -w
use strict;
use Net::SSH::Perl;

$ENV{HOME} = "C:";

my $host = "192.168.32.138";
my $user = "root";
my $passwd = "101010";
my %params = (
                protocal => '2,1',
                # debug => '1'
            );

my $ssh = Net::SSH::Perl->new($host,%params);
$ssh->login($user,$passwd);

my ($stdout, $stderr, $exit) = $ssh->cmd("ls /home");
print "$stdout";

---------------------clip-------------------------

When I run this script, there are so many problems showed as following.

Can't locate Math/Pari.pm in @INC (@INC contains: c:/Perl64/site/lib c:/Perl64/lib .) at C:/Perl64/site/lib/Net/SSH/Perl/Util/SSH2MP.pm line 6, <GEN1> line 1.

Compilation failed in require at c:/Perl64/site/lib/Net/SSH/Perl.pm line 52, <GEN1> line 1.

---------------------clip-------------------------

I try to use module Net::SSH to execute this idea, but I don't know how to handle the trust relationship between Windows and Linux.

coud you help me to check and resolve this problem? Or give me another idea for the communication between windows and Linux?

Thank you.

Best Regards,

Wei

"Can't locate Math/Pari.pm in @INC" Start by installing Math::Pari. `package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name`	[reply]

I recently implemented something like this with Net::SSH::Any... Here's a code snippet... `my $ssh = Net::SSH::Any->new($ipAddr, user => $user, password => $password, backends => [qw/Net::SSH2/], timeout=>1, kill_ssh_on_timeout=>1); $ssh->error and die "Unable to Connect via SSH to $mac, " . $ssh->error); my ($output, $errput) = $ssh->capture2($cmd);` [download]	[reply] [d/l]

Evidently Math::Pari failed to install. I ran into this recently, and: Copied .cpan/sources/authors/id/I/IL/ILYAZ/modules/Math-Pari-2.01080605.tar.gz into a working directory. Untar'd it, and changed into the uncompressed Math-Pari directory. Fetched and untar'd http://megrez.math.u-bordeaux.fr/pub/pari/unix/OLD/pari-2.1.7.tgz. perl Makefile.PL; make; make install For #4, on Windows, you'll probably use some other 'make'. See what 'perl -V:make' says.	[reply]

I think there's an nmake.exe. The thing is, I think mine came with my Visual Studio software. In fact, you might not even be able to get a standalone version of it anymore. If you do have Visual Studio and nmake (or even somehow just nmake), you can copy nmake.exe to the folder where you want to do your make. Here's Microsoft's instructions on how to run the tool. You don't have a Perl Package Manager you can use to install Math::Pari? That's how I get my packages. It even notes any dependencies you need for packages you want to install and automatically installs those as well, preventing problems like this. Perl Package Manager ~~comes with ActivePerl, and~~ makes package management much simpler than the way you're describing it. It looks like you can get PPM from CPAN!	[reply]

"You don't have a Perl Package Manager you can use to install Math::Pari? That's how I get my packages. It even notes any dependencies you need for packages you want to install and automatically installs those as well, preventing problems like this." Both ActiveState and Strawberry Perl have shipped with PPM and `cpan` for several years now. ActiveState doesn't ship with a C compiler or build tools, though they can be installed via `ppm MinGW` though currently only for the 32bit platform (note OP is using a 64bit perl), if you want to work with ActiveState 64bit you have to install this yourself. With a little effort installing modules and their dependencies via `cpan` is reasonably straightforward. IMHO any automated system for module installation is going to have it's short comings, and for cpan that (again, IMHO) is the level of verbose output you get on failure. It seems simply to confuse those who aren't used to software compilation. In other words those who are new, and this can be very discouraging. Perhaps we can work on that. Some of the popular PPM repos have been reported to me as 'out of date' or 'behind the times' recently. Part of that is perhaps due to them being run by individuals. I'm currently drafting a module installation tutorial covering modern module installation methods, and a FAQ on the subject. This will be posted for critique in the usual place before it makes it to tutorials.	[reply] [d/l] [select]

Hi, thank you :). I try to download a nmake application, but to my surprise, I didn't find it from Micorsoft Website, while I didn't use Visual Studio. Fortunately, I found the dmake application and it can be used to install the perl module. according to so many warm-hearted friends' advise, I found I didn't install the Net::SSH::Perl module correctly. I'm planning to re-install this module. Thank you so much Br, Wei	[reply]
Re^2: Communication between Windows and Linux via Perl by zhonghua (Novice) on Apr 11, 2013 at 14:14 UTC
Thank you, I have installed dmake to compile and isntall the Net::SSH::Perl module. Maybe I need to re-install it. Thank you. Br, Wei	[reply]

If you're going to recent version of your Distro's with Openssh 4+, try using Net::OpenSSH it works.	[reply]
Re^2: Communication between Windows and Linux via Perl by zhonghua (Novice) on Apr 11, 2013 at 14:43 UTC
Hi, I have tried to install this Net::OpenSSH, but this module can't installed on Windows platform. So I choose the Net::SSH::perl. Anyway, thank you Br, Wei	[reply]

Hi, You can try DWIM Perl. It comes with the Net::SSH2 Module pre installed. I have used it to login to a lot of Linux Boxes and Linux Based Storage Arrays and it works like a charm. Do a google search for DWIM Perl. For Net::SSH2, please read A little demo for Net::SSH2. Its really good. One thing that will help you is, insert a sleep interval - `sleep 10` in your script right after you do a `chan2->exec('somecommand');`. Perlpetually Indebted To PerlMonks `use Learning::Perl; use Beginning::Perl::Ovid; print "Awesome Books";` [download] http://dwimperl.com/windows.html is a boon for Windows.	[reply] [d/l] [select]

Hi Salva, Thank you for pointing that out. I have been using the module as shown in a tutorial posted here, but not sure where I am going wrong. I will be thankful if you could provide any pointers on how to use it correctly.

hi, Thank you for you good advice. :) Now I'm using Active Perl and Active Python, I'm used to Active product. I'll try it. Thank you. Br, Wei	[reply]

Install putty to your machine. This comes with plink, a command-line ssh client that doesn't use a terminal emulator window on the client side. Import your keyfile to the PuttyGen program and save it in putty's private key file format. Spawn plink from your perl script with something like `$error = system q(plink -i yourkeyfile.ppk root@192.168.32.138 "ls /ho +me" > outputfile.txt);` [download] Then, if $error is false, read the output file.

Hi Good idea. Very thanks. I'll try it. Up to now, the problem is still existing, but I'm too busy to finish this script. Some days later, I'll change a new environment and try again. Then I'll post the new progress. Thanks and Best Regards, Wei	[reply]
