[webmin-devel] using port 10.000 for ssl and 10.001 for http

Is there a way to have webmin running in both SSL and normal mode?
Even using the "stunnel" method described into the docs the normal mode 
will no longer work.

There's no built-in way to do this in Webmin yet, but you could run in
non-SSL mode on port 10000 and then setup stunnel to accept encrypted
connections on port 10001 and forward those to port 10000.

[webmin-devel] Integrate with Apache module?

I've written a module for managing multiple installations of Lasso
Server 9 (www.lassosoft.com)

Lasso Server integrates with Apache via FastCGI

I would like my module to be able to insert an Include directive into a
selected virtual host in order to allow that virtual host to hand off
requests for .lasso files to an instance of Lasso Server

Is there an easy way to do this by utilising the existing functions in
the Apache module? Or would I have to write my own code to parse the
virtual host entry and insert the directive?

Yes, absolutely - you can use code like this :

foreign_require("apache");
$conf = apache::get_config();
 <at> vhosts = apache::find_directive_struct("VirtualHost", $conf);
foreach $v ( <at> vhosts) {
  $sn = apache::find_directive("ServerName", $v->{'members'});
  if ($sn eq "whatever.com") {
     <at> includes = apache::find_directive("Include", $v->{'members'});
    push( <at> includes, "/path/to/file.lasso");
    apache::save_directive("Include", \ <at> includes, $v->{'members'}, $conf);
    flush_file_lines($v->{'file'});
    }
  }

Re: [webmin-devel] Integrate with Apache module?

Thanks for the quick response. Already got a select-list displayed with
a list of the defined virtual hosts. It's easy when you know how!

I'm stuck, hopefully something stupid you can easily spot..

I'm getting 'Failed to save Site : flush_file_lines called on non-loaded
file /etc/httpd/conf.d/ssl.conf' when running:

sub update_apache_vhosts {
	my ($site) =  <at> _;
	my $conf_path	= $site->{'directory'} . '/lasso/fastcgi.conf';
	
	# servernames from ui_select (multiple) on edit form
	my  <at> servernames	= split(/\0/, $site->{'servername'});
	
	foreach $servername( <at> servernames) {
		foreign_require("apache");

Ah, OK, that makes sense. Thanks.

Re: [webmin-devel] Integrate with Apache module?

I ended up setting a flag if something is changed. Here's the final
version that seems to be working great so far:

sub update_apache_vhosts {
	my ($site) =  <at> _;
	my $conf_path	= $site->{'directory'} . '/lasso/fastcgi.conf';
	
	my  <at> servernames	= split(/\0/, $site->{'servername'});
	
	foreign_require("apache");
	$conf = apache::get_config();
	 <at> vhosts = apache::find_directive_struct("VirtualHost", $conf);
	foreach $v ( <at> vhosts) {
		$sn = apache::find_directive("ServerName", $v->{'members'});
		 <at> includes = apache::find_directive("Include", $v->{'members'});
		my($changed,$match1,$match2) = 0;
		foreach $inc( <at> includes) {
			if($inc eq $conf_path) { $match1 = 1; }
		}
		foreach $servername( <at> servernames) {
			if($servername eq $sn) { $match2 = 1; }
		}
		# If Include is not present, but servernames match
		if($match1 == 0 && $match2 == 1) {
			push( <at> includes, $conf_path);
			$changed = 1;
		
		# If include is present, but no match on servername
		} elsif($match1 == 1 && $match2 == 0) {
			delete $includes[$inc];
