USB Drive On Mac OS X Full - No Files On Drive

I had a situation the other day where I had a 32GB USB Flash Drive that was "empty," but when I tried to copy a 3 GB file to the drive, I received an error that the drive was full or there was not enough space. How is this possible when there are no other files on the drive?

It has to do with the way MAC OS handles "trash." The other day I deleted 27 GB worth of files from the drive, and while your Trash bin remains full on the OS, the files are not actually deleted from your thumb drive, but rather moved to "hidden" or  .Trashes status - hoarding all of your free storage. 

There are a couple of ways to remedy this: Empty your Trash bin, manually delete the hidden files, or Format the drive (this will erase everything on it).

To manually delete the hidden files you may use the Terminal application or a 3rd party application to show these hidden files.

To Format your drive on MAC OS, follow these instructions.

How to disable WIFI on your Cox supplied Netgear Router (CG3000D)

You'll notice that if you try to login to the administrative web GUI for your Netgear Cox router there is not a tab that lets you uncheck "Enable Wireless Radio". You have to use a hidden settings page on the router to disable this setting. The URL for the page is as follows:

http://##ROUTERADDRESS##/Rg802dot11BasicCfg.asp    

use the IP address of your router where it says ##ROUTERADDRESS##. This might look something like this:

http://192.168.0.1/Rg802dot11BasicCfg.asp

On this page you will see a check box checked for "Enable Wireless Radio." Uncheck this box and hit APPLY below and your wireless will be disabled on this router and you are free to use a 3rd party wireless router of your choosing such as a ASUS RT-N66U Dual-Band Wireless-N900 Gigabit Router.

NOTE: Unchecking the "Enable SSID Broadcast" does not disable the WIFI. It only prevents the SSID from being broadcasted.

Cannot login to Cisco Call Manager After Firefox Update

After performing the last Cisco CallManager update we were unable to login into Cisco Call Manager 8.5 via the web interface. When we attempt to login we received the following message:

Secure Connection Failed An error occurred during a connection to YOUR IP. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message.

(Error code: ssl_error_weak_server_ephemeral_dh_key)

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. * Please contact the website owners to inform them of this problem.

The Cause:

Since the 30th of June of 2015, Mozilla Firefox doesn't support connections to a server with weak Diffie-Hellman ciphers anymore (Mozilla Release Notes:)

The Resolution:

Perform at your own risk. Accidental adjustment may effect Firefox's performance. To fix type about:config in your Firefox web browser, in the address bar. Change the next settings with the next values: 

security.ssl3.dhe_rsa_aes_128_sha=false
security.ssl3.dhe_rsa_aes_256_sha=false

The values should be true by default. Click on them to change to "false."

That's it! You should now be able to login to Cisco Call Manager.
