AOLserver::CtrlPort - Execute Commands on AOLserver's Control Port


    use AOLserver::CtrlPort;

    my $conn = AOLserver::CtrlPort->new(
        Host     => 'myhost',
        Port     => 3456,
        User     => 'username',
        Password => 'password',

    my $out = $conn->send_cmds(<<EOT);
        info tclversion

    print $out, "\n";


AOLserver::CtrlPort uses Net::Telnet to connect to a running AOLserver's control port, issues commands there and returns the output.

It is useful for creating test suites for AOLserver applications which can be controlled via the control port.

To configure AOLserver's control port, use settings similar to the following ones:

    ns_section "ns/server/${servername}/module/nscp"
        ns_param address myhostname
        ns_param port 3334
        ns_param echopassword 1
        ns_param cpcmdlogging 1

    ns_section "ns/server/${servername}/module/nscp/users"
        ns_param user "username:3G5/H31peci.o:"
                           # That's "username:password"

    ns_section "ns/server/${servername}/modules"
        ns_param nscp ${bindir}/nscp.so

This lets AOLserver enable the control port on server myhostname on port 3334. Authentication is on, the username is username and the password is password (hashed to 3G5/H31peci.o with a program like htpasswd).



Creates a new control port client object. The following options are available to the constructor:


The port AOLserver is listening to for control port commands.


The control port address as defined in the configuration.


Number of seconds after which the client will time out if the server doesn't send a response.


User name for control port login defaults to the empty string for non-protected control ports.


Password for control port login defaults to the empty string for non-protected control ports.


Send one or more commands, separated by newlines, AOLserver's control port. The method will return the server's response as a string. Typically, this will look like

    $out = $conn->send_cmds(<<EOT);
        info tclversion
        info commands

and return the newline-separated response as a single string.


AOLserver::CtrlPort is Log4perl enabled. If your scripts don't do what you want and you need to find out which messages are being sent back and forth, you can easily bump up AOLserver::CtrlPort's internal debugging level by saying something like

    use Log::Log4perl qw(:easy);

in your test script before any AOLserver::CtrlPort commands are called.

Please check out the Log::Log4perl documentation for details.
