McAfee Host Intrusion Prevention blocks Chromecast

There are multiple reasons why Chrome may display the Chromecast "No Cast devices found" message when you try to cast a webpage. One such reason is blocking that is performed by McAfee Host Intrusion Prevention. If you are running McAfee Host Intrusion Prevention, confirm this by opening it and click on the "Activity Log" tab. You may see multiple copies of the following message.

Google Chrome (chrome.exe) Blocked Incoming UDP - Source xxx.xxx.xxx.xxx : (xxxx) Destionation xxx.xxx.xxx.xxx Block All Traffic

To resolve this issue, you will need to add an exception to the Firewall.

Click on the "Firewall Policy" tab. Click Add.

On the Action and Direction page, enter "chromecast" as the Name. Select Either for the Direction. For Action, click Allow and click Next.

On the Protocol and Address(es) pages, for Network Protocol, select Any Protocol. Click Next.

On the Protocol and Ports page, click Next.

On the Application page, click Next.

On the Set schedule page, click Finish.

After these changes have been made, you should be able to access the cast device in Chrome. If not, you may have another problem. To isolate the problem, try the following.
  • disable the firewall
  • disable VPN connection

Accessing the CFE miniWeb Server page after installing DD-WRT

If you are accessing the CFE page from the default Belkin firmware, you should configure your client with a static IP of 192.168.2.x. However, if you have already installed DD-WRT and are trying to access the CFE page, you should configure your client with a static IP of 192.168.1.x.

See instructions here on how to access the CFE page.

Exporting NFS shares from OpenELEC 4.0

OpenELEC 4.0 does not automatically export shares of external USB devices. To do this automatically, create the samba.conf file.

cd /storage/.config
cp samba.conf.sample samba.conf

Add the following to the bottom of samba.conf.

[USB Drives]
path = /media
available = yes
browsable = yes
public = yes
writable = yes

Avoid security prompts when copying or moving files within your network

Windows may prompt you with a warning when you attempt to copy or move files across systems on your network.

To get around this problem, you will need to tell Windows that the other host computer is a system on your Intranet. Follow the steps below.

Go to Internet Options.
Click on the Security tab.
Select Local intranet and click the Sites button.
Click on the Advanced button.
In the Add this website to the zone: box, type
file://192.168.1.*
click the Add button.

Note: You will need to substitute 192.168.1 depending on your network setup. You may also specify hostnames like file://*.<domainname>.

Mounting OpenELEC shares from a linux client

If you are running OpenELEC, there may be the need to access the OpenELEC filesystem from a client computer. Unfortunately, simply enabling SAMBA (without setting a password) on OpenELEC only allows Windows clients to connect to it. For Linux clients, attempting to mount OpenELEC shares results in the system prompting for the password even though one is not set by default.

To resolve this issue, add a password for the SAMBA service in the OpenELEC configuration settings. Now both Windows and Linux systems can mount shares on the OpenELEC system.

Here is the command to mount a OpenELEC share from a Linux client.
sudo mkdir /mnt/openelec
sudo mount -o username=<OpenELEC SAMBA username>,password=<OpenELEC SAMBA password> //<host>/<share> /mnt/openelec

The default OpenELEC SAMBA username and password are openelec and openelec.

Latest DD-WRT firmware for Belkin Share Max N300 (F7D7301)

In a previous post, I described how to install DD-WRT onto the Belkin Share Max N300 (F7D7301) router. Since then, a number of firmware revisions have been released. I have had success with the revision r21676. It can be found below.

Note: There are yet newer revisions available, but please be advised that some revisions could be buggy and may corrupt your router. If you have had success with another revision, please let me know and I will add it to this page. Thanks.
