Shell Programming and Scripting

Hello ,

I am writing a script which takes the user name , password and hostname from the database and login to the server .

I am only able to login to the server and my script logs out and only I can run few command if I provide those command in my script else I am not able to run those command after logging in.

I need to run those command once I have logged in using my script and I want to track down all the commands being executed in a particular session.

I know how to run command on remote shell using script , but I want to open remote shell using perl and want to run the command manually and terminate the session when I am done as we normally do with shell .

Any help or guidance will be highly appreciated.

Thanks

You can use the following method,

Code:

# get data from database and form ssh
.
.
.
.
.

# execute the formed ssh to the remote machine.
# exec ( "ssh .... ...." )
# this will give you the remote shell, where you can execute the commands manually.. and exit..

Refer <b>perldoc -f exec</b> for further details

check if CPAN package Net::SSH is what you are looking for

yes I have net::ssh:erl and expect too
This script can execute can execute the command which is given in the script only but I want to enter the command manually and I should be able to terminate the session when I am done with my work.

here is the basic script which I am using to execute the few command but I want to generalize it

Code:

#!/usr/bin/perl -w
use Net::SSH::Perl
$host = '192.168.0.114';
$username = 'user';
$login_passwd = ''password;


my $cmd = "ls -l";
my $ssh = Net::SSH::Perl->new($host);
$ssh->login($username, $login_passwd);

my($stdout, $stderr) = $ssh->cmd("$cmd");
print "$stdout\n$cmd\n";

Thanks for the response

then what stops you from obtaining the command from STDIN and passing it as an argument to $ssh->cmd()

Thanks Yogesh,

But I may need to enter multiple commands and it may also depend on the situation of my requirement hence every time loging into the server and logging out is a problem , is there any way I can escape this and my script should login once and execute as many command as I want without logging out from the server .

Why not just run system("ssh user@hostname"); and let the user interact with it directly?
