I work in the IT department for the residential housing area at my university (network operations is separate from ours). I've wondered how is it that when someone registers a MAC address on our device registration portal [to get wired internet access on campus], BluCat Address Manager is able to detect whether it is a wired or wireless MAC address and assign an IP address from the campus specific ranges accordingly. I know that there's some companies that require you do remote work from a computer that has to be on a wired connection, and they have a programs bundled with the software they give you that can tell the difference, but I have no clue how such a thing would be implemented. Do you have any idea how this is done? Is it right to assume that if a program can figure it out, there's something about the content of the MAC address, or other identifier of the device, that can be looked to determine this? I would like to make a shell program that can replicate this for fun. In every case, this will be for a remote computer on the same network as mine, if that simplifies things.
I am not able to establish a wired network connection between two computers on which I just installed Ubuntu 10.04.
I am new to this environment. Unlike in the Windows environment, where it happens by just connecting them with a cable, Ubuntu keeps flashing a notification saying "Wired network disconnected". Am I missing a driver or something?
I am able to connect to the wi-fi router without issue. The wired connection is just not working.
The title is not a mistake, I really am talking about wired, not wireless.
Essentially, I was wondering if it was possible to password-protect a LAN wired network to enhance security and only allow computers knowing the password to join.
I thought about using MAC address filtering, but that is way too trivial to circumvent.
Any ideas?
Thanks!
How about this situation. Our business deals a lot with medical information. And some of our clients have demands based off HIPPA, etc. There is one now where they do not want an employee to have both wired and wireless on at same time. If the wireless is on the wired needs to be turned off automatically and vice versa. However, this can not be up to the end user to manage! I have looked for third party applications and only have found http://www.wirelessautoswitch.com Does anyone know of anything else that is out there? Or possible something that can be done via group policy, etc.?
I am consistently experiencing corrupt downloads over TCP/IP and Ethernet on a small LAN, the downloads are coming from different sources on the Internet. WAN is comcast cable.. NIC is brand new.
My theory is that this is being caused by a bad ethernet cable.
What are the possible causes? I am in the process of testing the ethernet theory now.
