Re: Control::CLI and Additional Prompt At Login

I figured out quite an easy fix for this a while after posting. Numerous rounds of testing have proven it out. I asked for the extra prompt to be changed from "ID:" to "ID>". This made my code think the login was all good. From there, I added code (through trial and error) to handle the extra prompt after the code block in my original message, like so:

$port = $cli->port;

if ( defined($port) ) {
    print "\tSSH connection to server ($host) established!\n";
} else {
    print "\tSSH connection to server ($host) could not be established
+... Exiting program.\n";
    exit;
}

$output = $cli->cmd("");
$output = $cli->cmd("IJAF");
$output = $cli->cmd("clear");
$output = "";

Thanks as usual, Monks!!

Sorry I'm late, but better late than never!.. The connect() method in Control::CLI only handles the connection, it does not try to lock onto a prompt; only login() and cmd() do that.. So I think the original problem was that you were sending your first command while the nix host was expecting the unique ID. So I would suggest a cleaner approach would be the following: `$cli = new Control::CLI( Use => 'SSH', Timeout => 30, ); $cli->connect( Host => $host, Username => 'abc', Password => 'pass', ) or do { print "\tSSH connection to server ($host) could not b +e established\n"; exit; } $cli->login( Username => 'IJAF', Username_prompt => 'unique ID[:>]\s$', ) or do { print "\tCould not get prompt from server ($host)\n"; exit; } print "\tSSH connection to server ($host) established!\n"; $output = $cli->cmd("clear"); ...` [download] The above login() method will now supply IJAF if it sees a prompt for the unique ID; once it sees a valid prompt (whether or not it got requested for the unique ID) it will return with a true value and you can then proceed to send the commands you need with cmd()..

So I think the original problem was that you were sending your first command while the *nix host was expecting the unique ID.

So I would suggest a cleaner approach would be the following:

$cli = new Control::CLI( Use     => 'SSH',
                         Timeout => 30,
                       );

$cli->connect(  Host            => $host,
                Username        => 'abc',
                Password        => 'pass',
             ) or do {
                 print "\tSSH connection to server ($host) could not b
+e established\n";
                 exit;
             }

$cli->login(    Username        => 'IJAF',
                Username_prompt => 'unique ID[:>]\s*$',
             ) or do {
                 print "\tCould not get prompt from server ($host)\n";
                 exit;
             }

print "\tSSH connection to server ($host) established!\n";

$output = $cli->cmd("clear");

The above login() method will now supply IJAF if it sees a prompt for the unique ID; once it sees a valid prompt (whether or not it got requested for the unique ID) it will return with a true value and you can then proceed to send the commands you need with cmd()..
