Ambit Cable Modem Web Interface

Time Warner Cable provides Ambit cable modems to their cable internet subscribers. You can get to the web-based interface by loading up the URL http://192.168.100.1 on a computer connected to your home network. If that doesn’t work, you may need to view that URL from a computer with the IP address 192.168.100.20. The default username/password for the web interface is: root/root

OS X – How to Change the MAC Address

Changing the MAC address of your network interface card can be useful for a number of things. Here is how you change it in both Tiger and Leopard:

For Tiger (10.4.x) open up the Terminal application and run the command:

sudo ifconfig en0 ether 00:00:00:00:00:00

where en0 is the network interface you wish to change the MAC address of, and 00:00:00:00:00:00 is the new MAC address you want the interface to use.

For Leopard (10.5.x) open up the Terminal application and run the command:

sudo ifconfig en0 lladdr 00:00:00:00:00:00

OS X – How to Hide a Partition from the Finder

Go to the Terminal and issue the command:

sudo setfile -a V /Volumes/paritionName

where “partitionName” is the name of the partition or drive that you want to hide. This hides the partition from being seen in the Finder but you can still access it from the terminal such as with scripts.
