无法SSH到远程计算机

Question

Not able to login to machine... but using the same credential i can log in to the machine

my $ssh = Net::SSH::Expect->new (host => "9.118.46.36", password=> 'test01', user => 'root', raw_pty => 1, timeout => 20);

    # establishes the ssh connection, 
    # authenticating with that user and password
    $ssh->login();

SSHAuthenticationError Login timed out. The input stream currently has the contents bellow: root@9.118.46.36's password: at /usr/local/share/perl/5.14.2/Expect.pm line 828

Answer 1

I increased the timeout to 30 and it works... Is there any way to check what should be the time out. As system load increase timeout 30 also may not work.
