could not send commands SSH session with Net::SSH::Expect

I am using Net::SSH::Expect to connect to the device(iLO) with SSH. After the $ssh->login() I'm able to view the prompt, but not able to send any coommands.

With the putty I can connect to the device and execute the commands without any issues.

Here is the sample script

my $ssh = Net::SSH::Expect->new (
'host' => $host,
'user' => $login,
'password' => $passwd,
'timeout' => 15,
'raw_pty' => 1,
'log_file' => "iloExpect.log",
);
if(!defined($connect=$ssh->login()))
{
print "Login Failed with the Host = $host Login $login and Password $passwd";
}
if($connect !~ /$prompt/i)
{
print "\nCould not get the prompt \n";
exit(1);
}
print "\nSending the command [$cmd]\n";
my $output = $ssh->exec('help');
print "\nOutput [$output]\n";



Thanks in Advance,

NAME
Net::CLI::Interact::Transport::SSH - SSH based CLI connection VERSION
version 1.121640 DECRIPTION
This module provides a wrapped instance of an SSH client for use by Net::CLI::Interact. INTERFACE
app On Windows platforms you must download the "plink.exe" program, and pass its location to the library in this parameter. On other platforms, this defaults to "ssh" (openssh). runtime_options Based on the "connect_options" hash provided to Net::CLI::Interact on construction, selects and formats parameters to provide to "app" on the command line. Supported attributes: host (required) Host name or IP address of the host to which the SSH application is to connect. Alternatively you can pass a value of the form "user@host", but it's probably better to use the separate "username" parameter instead. username Optionally pass in the username for the SSH connection, otherwise the SSH client defaults to the current user's username. When using this option, you should obviously only pass the host name to "host". ignore_host_checks Under normal interactive use "openssh" tracks the identity of connected hosts and verifies these identities upon each connection. In automation this behaviour can be irritating because it is interactive. This option, enabled by default, causes "openssh" to skip or ignore this host identity verification. This means the default setting is less secure, but also less likely to trip you up. It is equivalent to the following: StrictHostKeyChecking=no UserKnownHostsFile=/dev/null CheckHostIP=no Pass a false value to this option to disable the above and return "openssh" to its default configured settings. opts If you want to pass any other options to openssh on its command line, then use this option, which should be an array reference. Each item in the list will be passed to "openssh", separated by a single space character. For example: $s->new({ # ...other parameters to new()... connect_options => { opts => [ '-p', '222', # connect to non-standard port on remote host '-o', 'CheckHostIP=no', # don't check host IP in known_hosts file ], }, }); reap Only used on Unix platforms, this installs a signal handler which attempts to reap the "ssh" child process. Pass a true value to enable this feature only if you notice zombie processes are being left behind after use. COMPOSITION
