does the API encompass Webmin functionality?

Howdy K P,

Not directly, though there are two other ways to access the Webmin API remotely, with XML-RPC probably being the most appropriate. It's pretty low-level, though. We're thinking on ways to improve the API situation, and trying to come up with ways to make high-level functionality of the rest of Webmin available as a library.

At this point, for something as simple as what you're doing, you might find using ssh is simpler. Just install keys for all of the "slave" servers that don't require a passphrase on the "master" server, and then run whatever commands you need to run. Something like:

ssh virtualmin@virtualmin.com '/home/virtualmin/bin/updaterepo.sh'

This is what I do to execute our software repository update script whenever I rsync my local repo to the virtualmin.com one. If you don't have to do anything complicated, like modifying configuration files, this might always be the simplest choice.

There's a quick guide to setting up public/private keys here:

Hi all,<p>
Webmin's XML-RPC api allows you to call low-level module functions remotely .. basically, the API is the same as if you were writing your own module that was calling functions locally. For example, to list and create aliases you could use a program like this :<p>

[pre]

#!/usr/bin/perl

# Demo program to list mail aliases, and either create or delete one

use Frontier::Client;

use Data::Dumper;

chop($url = `cat url.txt`);

eval {

$server = Frontier::Client->new('url' => $url);

};

$@ && die "Failed to create server : $@";

$conf = $server->call("sendmail::get_sendmailcf");

$afile = $server->call("sendmail::aliases_file", $conf);

$aliases = $server->call("sendmail::list_aliases", $afile);

print "Found ",scalar(@$aliases)," mail aliasesn";

($already) = grep { $_->{'name'} eq 'foobar' } @$aliases;

if ($already) {

print "Alias foobar -> $already->{'values'}->[0] exists, deleting itn";

$server->call("sendmail::delete_alias", $already);

print "Done deletionn";

}

else {

print "Adding alias foobarn";

$alias = { 'name' => 'foobar',

'enabled' => 1,

'values' => [ "jcameron@webmin.com" ],

};

$server->call("sendmail::create_alias", $alias, $afile);

}

[/pre]

This code assumes that a file containing the Webmin URL exists in url.txt, formatted like :<p>

<i>http://root:password@webminserver:10000/xmlrpc.cgi</i>&lt;p&gt;

As you can see, this is pretty low-level .. many function calls are needed to perform even a basic task. Virtualmin offers an HTTP-based API that operates at a higher level, but it doesn't yet extend to clustering.&lt;p&gt;
