Well, I mean something like a shell prompt.
When you telnet to port 4555, you get no prompt.
If you telnet to Linux which bash shell, you might get the '-bash-3.00% ' prompt
(for example).
When using the Perl Net::Telnet module, it wants and expects a prompt to be
defined so it knows when it can send the next list of characters for a command.
So for example, if I could configure the prompt to be 'james> ', then this can
happen in my terminal:
-bash-3.00$ telnet localhost 4555
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
JAMES Remote Administration Tool 2.2.0

Login id:
root
Password:

Welcome root. HELP for a list of commands
james> listusers

james> quit
Bye
Connection closed by foreign host.
-bash-3.00$
* Note, the appearance of 'james> ' is a prompt I would like to have defined.
Currently you are given nothing to prompt you that you can start entering a command.
And then I could make a little PERL script to shutdown JAMES like this:
-bash-3.00$ cat james-shutdown.pl
##!/bin/bash
use Net::Telnet;
use strict;
my $telnet = new Net::Telnet (
Host => "localhost",
Port => "4555",
Prompt => "/^james>/");
$telnet->open();
$telnet->waitfor(/Login id:\s*\n/);
$telnet->print("root");
$telnet->waitfor(/Password:\s*\n/);
$telnet->print("********");
$telnet->cmd("shutdown");
print $telnet->getlines();
$telnet->close();
__END__
-bash-3.00$
So you can see one importance of having a defined prompt for the administrative
shell on telnet:4555 JAMES admin service.
If we admins want to execute automated tasks, like shutdown, add user, from
other programs/scripts, we need a prompt to appear to tell the script when it
can input information.
So I ask again. Can a shell prompt for the JAMES admin service on port 4555 be
defined? How can I do this?
Actually, I do not really care too much what the prompt is. I just want a prompt.

Wich is just what I've been writing last week :)
A patch against the trunk is attached, this adds an optional <prompt> element
to the remote manager handler block, like this:
<remotemanager>
<port>4555</port>
<handler>
<helloName autodetect="true">myMailServer</helloName>
<administrator_accounts>
<account login="root" password="root"/>
</administrator_accounts>
<connectiontimeout> 60000 </connectiontimeout>
<prompt>james></prompt>
</handler>
</remotemanager>
The prompt element is optional, when left out the prompt is set to an empty
string, so when the configuration is unchanged the behaviour also is
unchanged.

You don't need to use the admin tool to shutdown james, there are
start/stop scripts which can be used to automate james.
Having a prompt to allow scripts to perform admin tasks sounds like a
reasonable request though.
If you want to have a go at making the change yourself look at this file:
http://svn.apache.org/viewcvs.cgi/james/server/trunk/src/java/org/apache/james/remotemanager/RemoteManagerHandler.java?view=markup
and this block:
while (parseCommand(in.readLine())) {
theWatchdog.reset();
}
I think you need to output the prompt once before the while, and in the
loop.

Well, I mean something like a shell prompt.
When you telnet to port 4555, you get no prompt.
If you telnet to Linux which bash shell, you might get the '-bash-3.00% '
prompt
(for example).
When using the Perl Net::Telnet module, it wants and expects a prompt to be
defined so it knows when it can send the next list of characters for a
command.
So for example, if I could configure the prompt to be 'james> ', then this
can
happen in my terminal:
-bash-3.00$ telnet localhost 4555
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

* Note, the appearance of 'james> ' is a prompt I would like to have

Currently you are given nothing to prompt you that you can start entering a
command.
And then I could make a little PERL script to shutdown JAMES like this:
-bash-3.00$ cat james-shutdown.pl
##!/bin/bash
use Net::Telnet;
use strict;
my $telnet = new Net::Telnet (
Host => "localhost",
Port => "4555",
Prompt => "/^james>/");
$telnet->open();
$telnet->waitfor(/Login id:\s*\n/);
$telnet->print("root");
$telnet->waitfor(/Password:\s*\n/);
$telnet->print("********");
$telnet->cmd("shutdown");
print $telnet->getlines();
$telnet->close();
__END__
-bash-3.00$
So you can see one importance of having a defined prompt for the
administrative
shell on telnet:4555 JAMES admin service.
If we admins want to execute automated tasks, like shutdown, add user, from
other programs/scripts, we need a prompt to appear to tell the script when
it
can input information.
So I ask again. Can a shell prompt for the JAMES admin service on port 4555
be
defined? How can I do this?
Actually, I do not really care too much what the prompt is. I just want a
prompt.
