DynDNS Update Clients

2013-11-11T15:40:00.001-08:00

What is an update client?

An update client is a computer application or a feature in your router that keeps your hostname's IP address up-to-date with your registered domain name. Your IP address sometimes changes IP address (monthly, weekly, or even daily) without your notice, and this may cause all sorts of issues for client's using the domain name linked to a certain IP address. This update client is for DynDNS users.

How to setup VPN with PPTP Server in DD-WRT

2013-08-03T11:05:00.000-07:00

Setting up VPN on the DD-WRT firmware is an intermediate tutorial due to complex configurations and security settings. For those who doesn't already know what PPTP (Point-to-Point Tunneling Protocol) is; PPTP allows you to connect securely from a remote location (such as your office, home, or school) to a LAN (Local Area Network) designated at another location, such as your workplace/office.

Note: PPTP has some security flaws and is considered deprecated. An alternative you may find just as easy is OpenVPN.

To setup a VPN through PPTP, login to your web GUI (http://192.168.1.1) and navigate to Services > VPN where you will see under PPTP Server, disabled by default. Select Enable and fill in the following information accordingly.

"PPTP Server", "Broadcast address", and "MPPE encryption" should all be enabled. Once you've enabled those features, look a few options down to find "Server IP". Input an IP that is different from that of your router. For example, if your router IP is 192.168.1.1, you'll want to use 192.168.1.2. (However, using another IP that can come no where near that of your routers, for example, 192.168.4.0 may avoid any conflict errors or sudden disconnection.

For "Client IP", input an IP range that is in your range. You want to keep in mind here, how many hosts you want to allow to connect via your VPN. For example, if your router's IP is set to 192.168.4.1; you want to set your Client's IP range to 192.168.4.100-120 (If your desired permitted hosts is 20.)

For your "Chap Secrets", enter your desired username and password in the box below this settings. Your username and password should be entered in the following format.

user * password *

If you wanted to use the username: phantom and password: swordfish. Then the input will be phantom * swordfish *

After you've completed all the options above. Navigate to NAT/QoS > Port Range Forwarding > click "Add" twice.

1. VPN 1723 TCP 192.168.1.1 1723 Enable
2. VPN 1792 TCP 192.168.1.1 1792 Enable

Once done, click Save > Apply Settings. Navigate to Administration > Reboot Router. You must reboot your router in order for this service to be activated.

Set the Network Time Protocol in DD-WRT

2013-07-29T06:16:00.003-07:00

NTP Client (Network Time Protocol) is a software client that allows your router to sync it's time from a time server. If you haven't already set this up for your router, you might want to look into setting it up -especially if you're "Access Restrictons" and the "Traffic by Month" are enabled. If your router isn't synchronized with the right time, you may encounter some major problems with some services that the router has that uses dates and time to determine it's output.

Setting up the NTP client is easy if you know your time servers. To configure the NTP client, navigate to your web GUI (http://192.168.1.1) > Setup > Basic Settings and scroll down to the NTP Time Section.

Select "Enable" for NTP Client.
Choose your Time Zone for your location.
Set the Summer Time (DST) accordingly (See Time Zone settings below)
Enter the domain name or IP address of the Time Server.

Once, you've filled everything out, click Save and Apply Settings.

How to setup your home web server with Windows Server 2008

2013-07-28T00:07:00.001-07:00

Setting up your home web server is a fairly easy thing to do and deals mainly with port forwarding. However, there are a few settings to be configured and programs to install before your web server can be up and running.

If you're running Windows Server Enterprise 2008, there's a few settings you need to make on the operating system. But first thing first, you want to register your IP address with a domain name. There's plenty of free DNS services offered for this, but one of the most popular and widely used is DynDNS.org.

To do this visit DynDNS.org, create an account, and create a new host. Make your hostname and choose a domain name for it. Check the "Wildcard" box and choose "Host with IP address" for Service Type. For your "IP Address" click the link right under it that says "Your current IP address is: xxx.xxx.xxx.xxx" to automatically link your IP address to this hostname. Once you've completed those steps, click Activate to .. activate your hostname. The next step is to download the DynDNS Updater. This program automatically updates your hostname with your connected IP address, because every so often your IP address changes, and will require a manual IP update without the DynDNS Updater. You can download the program here: DynDNS Client Updater.

Before you install the DynDNS Client Updater on your server, make sure you configure the DDNS settings on your router. To do this, log into your web GUI (http://192.168.1.1) and navigate to Setup > DDNS. Fill in your information and use the username and password of your DynDNS account (not the routers). For your "Hostname" use the domain name (URL) connected to your IP address that you've just registered for at the DynDNS website.

Now that you've setup a domain name for your IP address, install the DynDNS Client Updater on your web server. When the installation is completed, you will need to login in order for you to enable the client's DynDNS service. Once you've enable the service on the web server, you want to configure some settings on your device's name.

To do this, open up your "Server Manager" and click "Change System Properties" under "Computer Information" to the right. You will not need to change your Server's/PC's name but you will need to add the DNS Suffix to the end of the server's/pc's name. You will need to restart your server upon this change, but before you do that, you can save some hassle by inputing your server's IP address into it's IPv4 settings.

Finally, after your server has restarted and you've logged back in. Open your router in web GUI (http://192.168.1.1), and navigate to QoS/NAT > Port Range Forwading. Name your application (in this case, I just named it toshiba-http) and forward ports 80 to 80. Protocol should be set to "Both" and IP Address should be set to that of your LAN IP server's address. Once, you've done that, select Enable > click Save > Apply Settings.

I'd say give it about 5 - 10mins for the settings to apply and then use the server's full name in any browser, and you should be directed to it's localhost files. In this case, the OS Windows Server Enterprise 2008 uses the platform IIS7.

Tweak your dual band Wireless Advanced Settings for better downloads and uploads speed

2013-07-19T21:09:00.001-07:00

You can optimize your wireless connection for both a single router in a network and/or multiple routers setup as a wireless client bridge. This is fairly easy todo. With just a few minor changes to your wireless settings, you'll be able to optimize your connection speed.

Before

After

For single Router networks
If you have a single router in your network, log into your web GUI (http://192.168.1.1). Login with your username and password and navigate to Wireless > Basic Settings.

Under your 2.4GHz wireless band settings, locate "Wireless Network Mode" and change that to NG-Mixed. For "Channel Width" select 40MHz.

Under your 5GHz wireless band settings, locate "Wireless Network Mode" and change that to NA-Mixed. For "Channel Width" select 40Mhz.

Figure 1-1

Click Save > Apply Settings. Once the settings have been applied, navigate to Administration > Management and click Reboot Router. It's always a good idea to reboot your router after making changes. Upon restart, check your connection speed, I like to use speedtest.net.

For Multiple Routers, you apply the same settings on all devices, the only difference is you have a wireless client bridge, make sure you reconnect to your wireless upon restart. To do that, navigate to Status > Wireless and click Site Survey > and select your wireless.

Creating a Wireless Client Bridge

2013-07-10T22:19:00.001-07:00

If you're using dd-wrt sp1, do not attempt this tutorial. You will not be able to configure a wireless client bridge in this version, so be sure to check your device's dd-wrt firmware version and update accordingly before starting this tutorial.

Assuming that your primary router is already flashed with dd-wrt v24 sp2 and setup with a home network with a LAN IP address of 192.168.1.1. If your primary router has a different LAN IP address, just adjust the IP accordingly to match that of yours and everything should work fine. There is no need to configure your primary router in this tutorial (although, in some cases - the wireless security needs to be changed to WPA2 Personal on both the primary and secondary router for it to work.)

Once you're done flashing your secondary router to sp2, turn your wifi connection off. Turning off your wifi connection while processing the config of your secondary router will prevent any errors or sudden disconnection that will result in a bricked router or even something worse.

Connect to the web GUI via a web browser (http://192.168.1.1) and enter your desired username and password. Navigate first to Wireless > Wireless Security. Change your wireless security to match that of your primary's router.

Figure 1-1

After you've input the wireless security of your primary's router, click Save > Apply Settings. (Most people who has tried different Security Mode other than WPA2 Personal has encountered problems, thus using WPA2 Personal will prevent any connection errors.)

Navigate to Wireless > Basic Settings > Under "Wireless Mode" select "Client Bridge" and input your primary's router Wireless Basic Setting's information. Once you've completed that, click Save > Apply Settings.

Figure 1-2

Note: I set my ACK Timing to 0 because my device is an atheros, thus my ACK Timing is set to "Auto" because 0 = Auto in atheros devices.

Check to ensure all information has been inputed correctly and then navigate to Setup > Basic Setup. Because your primary router already has an IP address of 192.168.1.1, you will want to use another IP address that is available. In this case, I've used Fing to derive all IP address in use and make my secondary router with an unused IP address. In this case, I've used 192.168.1.2.

Figure 1-3

Click Save > Apply Settings. Wait about a good 10 minutes and then navigate to your web GUI with the IP address you've set for your secondary router (client bridge)

Note: If you've enabled "Time Settings" on your primary router, change your secondary router (the client bridge) to match that of your primary router (AP). You can also leave your "Local DNS" at 0.0.0.0.

Next, navigate to Security and uncheck all boxes under "Block WAN Request" except for "Filter Multicast" and click Save. Once you've clicked Save, disable the "SPI Firewall" and click Apply Settings.

Figure 1-4

Once you've applied your settings, navigate to Setup > Advanced Routing and under "Operating Mode" select Router.

Figure 1-5

Click Save > Apply Settings. And navigate to Status > Wireless and under "Wireless Mode" click Site Survey. Select your current wireless and click OK. It will then bring you back to the Wireless Setup page. Verify that all information inputed are correct and click Save > Apply Settings.

Figure 1-6

Finally, navigate to Administration and scroll down to click "Reboot Router". Upon completion of rebooting, you should be able to open a web browser and navigate to a website (ie. http://www.google.com)

If you're able to connect to the URL, you've officially set up a wireless client bridge. You can connect both through the primary and secondary router's web GUI.

Setup Remote Desktop for on the go access

2013-07-06T13:06:00.000-07:00

Windows Remote Desktop

Setting up Remote Desktop for your windows operating systems is fairly easy. Once you've set up your network and have your PC's connected to it, you'll automatically be able to connect to them remotely after changing the windows remote desktop connection option. However, you'll notice that when you're out at Wal-Mart or waiting at the dentist office, you wont be able to remotely connect to your windows operating system that has all your work documents on it. This is because your PC is only recognized as a trusted device when you're connected to your wireless network.

The problem here is to get your network to recognize your device, be it a mobile phone or desktop PC as a trusted device and grant access to the network you wish to connect to.

First off, you want to register your ip to a domain with DynDNS or any other domain name service so you won't have to memorize your ip address when trying to connect to your remote device. This is optional and doesn't have to be done, but is added for your connivence. This is also useful to do because every now and then, your ip address may decide it wants to change up numbers, thus becoming a whole new ip address you'll have to re-memorize. But with the DynDNS updater, it automatically updates the domain name with the new ip address for you, and U.E.N.O. it..

Now that you have registered a domain name for your ip address and installed the updater onto the device you'd like to connect to remotely, you have to configure your router to grant access to you when your on the go.

If you registered your domain name with DynDNS, log into your router and navigate to Setup > DDNS and fill in your information. Select the DNS service and fill in your username and password that you used to sign up for the service (not your router's username and password). For the Hostname, use the domain you registered for your ip (ie. evergreen.dyndns.org). Check wildcard if you've enabled it and click Save > Apply Settings.

Next, navigate to NAT/QoS > Port Range Forwarding > Add and name your Application. In this case I named it "Device-RDP". Under "Start" and "End" use port number 3389 and use Both under "Protocol". Under "IP Address" use the LAN IP address of your remote device (ie. 192.168.1.140), and check Enable and click Save > Apply Settings.

Finally, on your windows computer, right click on "Computer" an select "Properties". Click "Remote Properties" and select "Allow connections from computers running any version of Remote Desktop (less secure)" and click "OK".

Under Computer Name, click "Change settings" > "Change" > "More" and enter your DNS (domain name) and click "OK". Make sure to restart your PC. Once restarted, open Remote Desktop and type your device DNS (ie. device1.evergreen.dyndns.org) in and click "Connect" and Boom!

How to add a USB storage device to your network

2013-07-04T23:06:00.002-07:00

If you want to attach a USB storage device to your network's router running the DD-WRT v2 sp24, you should have the following materials ready and set up at hand.

External USB storage device.
Router (flashed with DD-WRT v2 sp24)

First thing first, if your storage device already has documents on it; back up all files to an existing folder and format your external storage device to MS-DOS format.

Next, you will want to attach the external storage device to your router's USB port. Navigate to Services > USB > select Enable for Core USB Support, USB Storage Support, and Automatic Drive Mount.

Give it about 10-20 seconds to show you where the external storage has been mounted.

Access to a 2TB storage device

In this example, the disk has been mounted here: /tmp/mnt/disc0-part1

Use this location to mount your disk in the terminal like so:

For the disk to securely mount:

Open your terminal
Type the following code into your terminal one by one. (Replace the segment in quotes to fit that of your external drive location.

mount --bind "/tmp/mnt/disc0-part1" /mnt
mount -n --bind "/tmp/mnt/disc-part1" /mnt

After you have typed the code in your terminal; type exit, and navigate to Services > NAS > and enable Samba. Type in your workgroup name and select the path your storage device under Path. Name your path and create a username and password used to access the path. Check the path name under Access Shares and click Save > Apply.

Wait about 10 seconds and you should then see your Router under your Devices. Select it and enter your username and password to access the storage device.

Keep your client bridge connected at all times

2013-07-03T23:47:00.000-07:00

wireless client bridge

Here is a script that is useful if you have a wireless client bridge in your network. A wireless client is good to have within your network because it adds scalability and efficiency to your network. Nevertheless, in order for it to be reliable in the network; it has to be connected to your main router at all times. If you are experiencing a disconnection between your main router and your wireless client bridge often; you may want to add this script to your main router.

If you are running dd-wrt v24 presp2, you can add this script to your start up to ensure connection between your main router and your wireless client bridge.

In the main router's web GUI, navigate to Administration > Commands and copy and paste the following script in open text box. After you have edited the script to your wireless bridge's ip address click Save Startup

#!/bin/sh

# This script solves an intermitent problem on my
# NetGear WNDR3300 wireless N radio.  Every few
# hours,  the wireless N radio stops broadcasting
# and cannot be seen by wireless clients.  Bringing
# the wireless interface down and then back up
# resolves the issue.  This script pings a
# wireless client, in my case, a WET610N wireless
# bridge that should always remain up and only
# connects to the wireless N radio.  If the
# ping fails twice within a given time, it
# brings the interface down and then back up.

# A wireless client that should always be up
CLIENT_IP=192.168.1.2

# Wireless interface that disappears
INTERFACE=`nvram get wl0_ifname`

# seconds to wait after failed ping to try again
FAIL_AGAIN=10

# seconds between checks
CHECK_EVERY=60

# after cycling, wait this many seconds
AFTER_CYCLE=360

# Client must be up before starting main loop
while true
do
  if ping -c 1 ${CLIENT_IP} >/dev/null
  then
    echo "${CLIENT_UP} ok - begining main loop"
    break
  fi
done

# main script
while sleep ${CHECK_EVERY}
do
  if ping -c 1 ${CLIENT_IP} >/dev/null
  then
    echo "${CLIENT_IP} ok"
  else
    echo "${CLIENT_IP} dropped one"
    sleep ${FAIL_AGAIN}
    if ! ping -c 1 ${CLIENT_IP} >/dev/null
    then
      echo "${CLIENT_IP} dropped two, sending restarting ${INTERFACE}"
      # on Atheros hardware instead use: ifconfig ${INTERFACE} down
      wl -i ${INTERFACE} down
      sleep 3
      # on Atheros hardware instead use: ifconfig ${INTERFACE} up
      wl -i ${INTERFACE} up
      sleep ${AFTER_CYCLE}
    fi
  fi
done 2>&1

Note: Where it says CLIENT_IP, change the ip to that of your wireless client bridge.

What is DD-WRT?

2013-05-31T16:44:00.000-07:00

dd-wrt - "power to the router"

DD-WRT is a Linux based alternative OpenSource firmware suitable for a great variety of WLAN routers and embedded systems. The main emphasis lies on providing the easiest possible handling while at the same time supporting a great number of functionalities within the framework of the respective hardware platform used.

The graphical user interface is logically structured, and it is operated via a standard Web browser, so even non-technicians can configure the system in only a few simple steps.

Apart from the simple handling, speed and stability are also in the focus of our development work. Compared to the software preinstalled on many WLAN routers, DD-WRT allows a reliable operation with a clearly larger functionality that also fulfills the demands of professional deployment.

The huge user community gives support to DD-WRT developers and the users themselves in various ways. Thanks to this, potential flaws in the system can be detected very quickly and can thus be corrected without delay. DD-WRT users can find help and suggestions from other users in the user forums, and the Wiki containing further information and how-to guides is being expanded and maintained by the DD-WRT community as well.

For devices mainly used for private purposes, DD-WRT is freely available. Platforms used for commercial purposes require a paid license. Compared to the freely available version, the professional version also allows for configuration of the WLAN parameters, thus opening up the opportunity of creating e.g. reliable and powerful network infrastructures. Special demands can be fulfilled by specifically tailored versions of DD-WRT.

Main characteristics:

supports more than 200 different devices
comprehensive functionality
supports all current WLAN standards (802.11a/b/g/n*)
supports outdoor deployment*
supports enhanced frequencies *
VPN integration
supports various Hotspot systems
bandwidth management
multilingual user interface
*appropriate WLAN hardware required
