My new Network Layout with Astaro

So I being a Comcast customer, not by choice, decided I wanted to be able to more closely monitor and control my network usage. I was toying around with different ways to monitor my traffic but didn't want to replace my router not add another device to the network outside the router.

I also looked at monitoring traffic per device, but this has its own problems such as missing traffic and counting local traffic twice, once on the source and again on the destination. The long an the short is I can only do what I want by having the traffic bass through a single device, an Astaro Security Gateway in my case.

I do run VMware Server on my single server though and desided if I could get a configuration with the ASG running in a virtual machine thus not needing the extra hardware. While, after a few hours of testing, and restoring my router once, I got it up and working. Heere is a diagram of the layout and soem notes.

Black lines on white are pyisical network connections.
Black lines on blue are vmware bridge connections.
Green lines indicate internal network traffic.
Red lines indicate external network traffic.

Some variouse notes on my configuration:

• The monitored internal netowrk is on the 192.168.1.* subnet.
• The unmonitored external network is on the 192.168.1.150.* subnet.
• Both networks exist on the same pyisical switch but the DHCP server doles out only internal addresses. A computer could be configured staticly to the external subnet and I havn't found a way to prevent this but in oder to circumvent the ASG the user would have to know about the second subnet.
  
• The server has only a single gigabit network interface card on it. Traffic on the internal network heading out will go to the server and be passed onto the ASG's internal virtual interface. Next the ASG will proccess the traffic and send it back out on the external interface. The server will pass the traffic back out on its internal interface but the traffic will really be on the external subnet so it will pass off to the router.
• The internal and external networks co-exist on the same network segment just differnet segments, for that reson I pourpasly left on the main routers Firewall and NAT.
• There is no noticible impact on network preformance as the traffic is already limited by teh 6M cable modem connection.
• I can not monitor just the external interface of teh ASG for trafic usage statistics with vnstat.
  

Flex DateChooser Toggle

Upadte- 2/4/2009 3:11 PM
Added support for simulating the shift key as well. If allowDisjointSelection is set then each click will toggle a date like id did before.
If it switched off though now the first click will set a start date and the second click an end date so that a range can be selected via clicking.

---

This component changes the DateChooser class to add a toggle option. When set clicking on a date will toggle it in the same way that control-clicking does.

  *   will set the start date and the second click will set the end date.  In this mode a third click will un-select the first range and 
  *   set a new start date.

New Styleized Photo's

I was playing around with some pictures from my trip to Denver last month and posted some new stylized photo's on my flicker page. Check them out here. The original photos are also available here.

Google Chrome theme for Firefox

This is how my Firefox looks. Note that this isn't maximized or trimmed, there just isn't a title of menu bar. The menu is accessible via a drop down on the top right as well as window controls.

Here is a list of the addon's and tweaks I used to get this look:

• Chromifox: This is the primary theme used.
• Stylish: For minor CSS tweaks.
  
  • Chromifox Falconer: Move the tabs to the top of the screen.
  • Chromifox Fixes: Fix for Zombie mode and minimized tabs.
• Autohide: This extension allows you to go into Zombie mode and hide the titlebar.
• Compact Menu 2: This extension allows you to hide the main menu and add a toolbar icon instead.
• FaviconizeTab: Lets you minimize tabs to just show their icon.

Extra settings:

• When using Autohide you will need to open up about:config and set the setting extensions.autohide.zombieBorder to 0. This will remove the titlebar and border when you go into zombie mode. (Shift-F11)

Runnig Firefox Pre Releases

I always like the latest and greatest so here are instructions for running the latest and greatest Firefox builds while maintaining browser auto-updated and extensions.

First off you need to download the latest night build from http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/. Alternately you can get the 3.1 Beta witch is not updated as often but still has the newest features at http://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.1b1/. The second option may be more stable but it will replace your Firefox install where as the nightly installs in a separate location.

Regardless of witch version you install when done you will have a few problems, namely most ad dons will report out of date and won't load. To fix this open up Firefox and navigate to about:config. Now search for the setting extensions.checkCompatibility or add it if needed. Also set it to false. This will simply make extensions load even if their versions don't match Firefox. Now some addon's still may not work but all of my major addon's work just fine.

Also while here we want to change a few other settings. Next find the setting general.useragent.extra.firefox and set it to Firefox/3.0. This just changes the Firefox version reported to web sites so the Install Extension links in https://addons.mozilla.org/en-US/firefox still work correctly.

Also we want to enable the new TraceMonkey Javascript Engine witch is much faster and one of the best features of 3.1. To do so again in about:config find the setting javascript.options.jit.content and set it to true.

You should now be all set, just restart Firefox and check out some sites. Also note that extensions and settings are shared between all versions of Firefox but noting we changed will break Firefox 3.0.

Comfigure Gmai to stay online in Mail.

Here is another tip for Gmail users that want to work in Mail.app.

When you set up a Gmail account in Mail.app it will default to POP. Now that Gmail supports IMAP you can use that instead. The difference between the two is simply that POP downloads everything from the server and works locally where as IMAP access the server and works directly there.

The two major benefits to using IMAP are that any changes you make to your mailbox locally. First of moving a message from one folder to anther is reflected on the server and secondly only a list of message is retrieved instead of the entire mailbox.

The second benefit isn't quite true though as Mail.app by default downloads the entire mailbox and all the attachments for offline viewing. Now as I rarely use Mail.app and furthermore never use the offline mode, I disabled this feature and substantially improved the Gmail synchronization. Not only the headers are cached and the message and attachments are retrieved when I open a message.

To change this setting you will need to remove your Gmail account, to clear out the cache, and add it again, this time manually set it up and on the last screen uncheck "Take this account online". This will prevent syncing. Now go to the Advanced tab and change "Keep a copies of messages for offline viewing" to "Don't keep copies of any messages".

Problem Syncing Gmail with Mail 3.0 in OS X 10.5

I general use Gmail via the web but I do have it configure in Mail.app for IMAP access as well for sending photos and files more easily. I was trying to send some photos today and had a problem with mail hanging as it were. It wasn't exactly crashing, but upon launching it would just sit there trying to sync and send files but never succeed. This blocked access to the IMAP. I verified the configuration but there were no problems.

As it turns out the problem was that Mail.app was trying to redo some task that had failed at an earlier time and these tasks were no invalid. Probably send some photo's that no longer exist. To clean up this problem just execute this command in a the terminal.

rm ~/Library/Mail/IMAP-*/.OfflineCache/*

Flex DataGrid LookupColumn

Update- 10/27/2008 3:27 pm
Updated the LookupColumn control to search for items via a hash array. The old code would loop through the source for each item witch would make the computation do R*N checks not a has array is created so that only R check's are needed. This makes a big difference is there area are large number rows or lookup items.

I highly recommend updating to this code to make renders run faster.

---

Here is another useful Flex component. This is a DataGridColumn that can be used to do simple lookups from another source when the DataGrid is rendered. You can use it to full data from a second source without having to first merge the data of write custom label functions.

Here is a simple example:

private const myGroups:ArrayCollection = new ArrayCollection(
[{groupid: 1, name: "Admin"},
{groupid: 2, name: "User"},
{groupid: 3, name: "Guest"}]);

<mx:DataGrid dataProvider="{}">
<mx:columns>
 <mx:DataGridColumn headerText="User Name" dataField="username"/>
 <LookupColumn headerText="Group" dataField="groupid" labelField="name" source="{myGroups}"/>
</mx:columns>
</mx:DataGrid>

LookupColumn.as
package hines
{
 import flash.events.Event;
 
 import mx.collections.ArrayCollection;
 import mx.controls.dataGridClasses.DataGridColumn;
 
 [Exclude(name="dataTipField", kind="property")]
 
 /**
  * This class is a custom DataGridColumn taht will look up each item in another array and fill in a field from the found item in its place.
  * 
  * Example:
  * private const myGroups:ArrayCollection = new ArrayCollection(
  *   [{groupid: 1, name: "Admin"},
  *   {groupid: 2, name: "User"},
  *   {groupid: 3, name: "Guest"}]);
  * 
  * <hines:LookupColumn headerText="Group" dataField="groupid" labelField="groupname" source="{myGroups}"/>
  * 
  * This will cause and rows with a groupid of 1 to render as "Admin" and so on.
  * 
  * This will also work with a xml source and the lookupField can be used if the field names differ.
  * 
  * <hines:LookupColumn headerText="Users Group" dataField="usersgroupid" lookupField="groupid" labelField="groupname" source="{myGroups}"/>

if [ -d /media/"$*" ]; then
  echo "Unmounting '$*'..."
  sudo umount -d /media/"$*"

  sudo mkdir /media/"$*"
  sudo mount -o loop "$*" /media/"$*"
fi
else
  echo "No image found to mount."
fi

Nautilus Script:

~/.gnome2/nautilus-scripts/(Un)Mount ISO

MediaWiki Blacklist Extension

This is an older extension I wrote for MediaWiki to allow the blacklisting of various pages.

To install the extention just ave the code below to blacklist.php in MediaWiki's extensions folder and add the following line in the LocalSettings.php file:

include_once("extensions/blacklist.php");

Example: To block some special pages for normal users, but not sysops, do this.

$wgWhitelist['sysop']['read']  = $wgBlacklist['*']['read'] = array("Special:Export", "Special:Listusers", "Special:Ipblocklist", "Special:Log", "Special:Allmessages");

Or with a RegEx:

$wgBlacklistOps["useRegex"] = true;
$wgWhitelist['sysop']['read'] = $wgBlacklist['*']['read'] = array("^Special:(Export|Listusers|Ipblocklist|Log|Allmessages)$");

blacklist.php
<?php
/*
    Blacklist Mediawiki Extension
    By Jeremy Pyne  jeremy.pyne@gmail.com
 
    This extension adds support for a $wgBlacklist array, layed out like $wgGroupPermissions, to support overrides.
        For example I can set $wgBlacklist['*']['read']  to diable specific special pages or
        make some pages of the site only visible for special groups.
    This blacklisting is done from lowest to highest powered groups and is implisit.  IE if you deny Main Page to User, it also denies it for all parent's of user.
        To override a blacklist at a higher level ou have to add an entry to $$wgWhitelist['sysop']['read'] to re-enable the pages if you are a sysop.
 
    Options: 
        $wgBlacklistOps["useRegex"] = true;
                This setting dictates whether to tread the page lists as regular expressions or not.  Though turning regular expressions off is much faster, you can not 
                mark page groups, partial page titles, or variations of title formating.
 
    Example: To block some special pages for normal users, but not sysops do this.
        $wgWhitelist['sysop']['read']  = $wgBlacklist['*']['read'] = array("Special:Export", "Special:Listusers", "Special:Ipblocklist", "Special:Log", "Special:Allmessages");
    Or wth a RegEx
        $wgBlacklistOps["useRegex"] = true;
        $wgWhitelist['sysop']['read'] = $wgBlacklist['*']['read'] = array("^Special:(Export|Listusers|Ipblocklist|Log|Allmessages)$");
 
     Note: This is not flawless method as page inclusions and such can get around this.

Switch Statment for Smarty

There is a complete and working switch plugin. It works exactly as a php switch and you can even use variables and modifiers for the conditions. Feel free to use it and let me know if you have and problems.

11/23/2010
I moved the code to github for matinance. https://github.com/pynej/Smarty-Switch-Statement/archives/Smarty-2.0

03/08/2008 - Updated to version 2
This update changes the break attribute to work how you would expect. That is, setting the break attribute will cause smarty to automatically render a {break} tag before it starts the NEXT case or default section. I strongly recommend updating to this version of the switch plugin, as the older version was very counter intuitive in this aspect.

02/09/2010 - Posted Smarty 3 Version
A separate version of this plug-in is available for Smarty 3 here.

(Also, this does work with nested switches, witch is why you see it accessing the _switchData variable. Be sure to not alter this variable in smarty code, as it will make the switches behave incorrectly.)

Both of these blocks will produce identical switch logic.

{case 1 break}
Code 1
{case 2}
Code 2
{default break}
Code 3

{case 1}
Code 1
{break}
{case 2}
Code 2
{default}
Code 3
{break}

03/08/2008 - Updated to version 2.1
Added {/case} tag, this is identical to {break}.

MediaWiki Tidy URLs

This article describes how to configure nice URLs on MediaWiki. The wiki page on the topic is rather massive and hard to understand so here are the instructions for Apache2.

Before:
http://my.domain.com/wiki/index.php?title=Main_Page&action=view

After:
http://my.domain.com/wiki/Main_Page/view

Add the following likes at the end of LocalSettings.php. Update $wgScriptPath to reflect you install.

LocalSettings.php
$wgScriptPath  = "/wiki";

$wgArticlePath = "$wgScriptPath/$1";

$actions = array('view', 'edit', 'watch', 'unwatch', 'delete','revert', 'rollback', 'protect',
              'unprotect','info','markpatrolled','validate','render','deletetrackback','print',
              'dublincore','creativecommons','credits','submit','viewsource','history','purge');

foreach ($actions as $a)
$wgActionPaths[$a] = "$wgScriptPath/$1/$a";

Enable the loading of the mod_rewrite.c module.

LoadModule rewrite_module /usr/lib/apache2/modules/mod_rewrite.so

Add the following to your httpd.conf or virtual site. Again, replace /wiki as needed.

RewriteCond %{REQUEST_URI} /(view|edit|watch|unwatch|delete|revert|rollback|protect|unprotect|info|markpatrolled|validate|render|deletetrackback|print$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/wiki/(.*)/([a-z]*)$ /wiki/index.php?title=$1&action=$2 [L,QSA]

RewriteCond %{REQUEST_URI} !/wiki/images
RewriteCond %{REQUEST_URI} !/wiki/skins
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/wiki/(.*)$ /wiki/index.php?title=$1 [PT,L,QSA]

Flex DateUtil Class

Upadte- 10/8/2008 1:26 PM
Added DateUtil.create() and DateUtil.clone() static methods. These can be used to work with a existing date. The Clone will cause updates to the original source where as the clone will not.

DateUtil.clone(StartDate.selectedDate).date;

Upadte- 10/10/2008 9:54 AM
Fixed a problem with the getters corrupting the date.

---

When working with dates and times in flex I found myself wanting to make simple changes like adding a day or trimming off the time witch turned out to be quite a few lines of code. Here is a example of setting a Date Field to yesterday and trimming off the time.

[Bindable]
private var prevDate:Date;

prevDate.hours = prevDate.minutes = prevDate.seconds = prevDate.milliseconds = 0;
prevDate.date--;

// Update the DateField.
dtDate.selectedDate = prevDate;
dtDate.dispatchEvent(new CalendarLayoutChangeEvent(CalendarLayoutChangeEvent.CHANGE));

<mx:datefield id="dtDate" change="" selecteddate="{prevDate}">

As you can see this is a rather large chunk of code to just change the date so I decided to create a DateUtil class. Here is the same operation using the DateUtil class.

<hines:DateField id="dtDate" change="" selectedDate="{DateUtil.now.subtract(DateUtil.DATE, 1).date}"/>

Here are some more examples of the DateUtil class.

var time:Date = DateUtil.now.time;
var monday:Date = DateUtil.now.assign(DateUtil.DAY, 1).date;
var then:Date = DateUtil.now.add(DateUtil.HOURS, 2).datetime;
var day:Number = DateUtil.now.fetch(DateUtil.Day);

Here is the custom class. Feel free to use it just credit me. If you have any problems let me know.

DateUtil.as

  * Add a month:
  *         DateUtil.now.add(DateUtil.MONTH, 1).date;
  *
  * Go to Monday:
  *         DateUtil.now.assign(DateUtil.DAY, 1).date
