Great just what we want, but we will not know the address that has been issued. If using the Pi at home it will connect to the network through the ethernet cable to your hub where it will be assigned an IP Address. If you are using the Raspberry Pi 3 it does come with a built-in WiFi connection, however, at least to begin with we will need a wired connection as we have no method of specifying the WiFi network to connect to if we have not added a screen and keyboard. This is the network address that we need to connect to. The difficulty we have to overcome is locating the IP Address of the Pi. Once a connection has been made then you can work on the command line or install something like XRDP to allow remote desktop connections to the Pi. You will need to download and install this. On Windows based systems there is an SSH client available at no cost called PuTTY. Connecting is simple using the SSH client from another Linux host or Apple OSX system. You can find many of my TR articles in a publication listing at Apotheonic Labs, though changes in TR's CSS have broken formatting in a lot of them.As we have already mentioned the Secure Shell Server is running by default on the Raspberry Pi, certainly in the Raspbian Distribution. I'm an active member of a great many Internet-enabled and meatspace computing enthusiast and professional communities including mailing lists, LUGs, and so on.\ I started just in time to see an IBM 7072 in operation.\ I've been playing with computers off and on since about 1980. Both parents have worked in IT/IS about as long as I've lived, and I have an enthusiastic interest in computing even outside my profession. I have also written hundreds of articles for TechRepublic.\Īside from directly work-related skills, I'm an ethical theorist and industry analyst with a keen eye toward open source technologies and intellectual property law. I was sad to give it up, but moving to Colorado kinda makes working in a Florida datacenter difficult. I was at one time the datacenter technician for the Wikimedia Foundation, probably the \"coolest\" job I've ever had: major geek points for being the first-ever paid employee of the Wikimedia Foundation. I hold both MS and CompTIA certs and am a graduate of two IT industry trade schools. I'm an IT consultant, developer, and writer. If that doesn’t convince you that MAC filtering does not provide real security, I don’t know what will. There are, of course, numerous free utilities you can download to make this change for you as well (such as Macshift for MS Windows XP).Īll of these techniques can of course be automated by self-propagating malware, and the creation of the malware can even be automated to some extent by existing malware creation “kits”. The location of that key varies from one MS Windows version to the next, but find that and you can just edit it yourself. MS Windows: On Microsoft Windows systems, the MAC address is stored in a registry key. If you give it a MAC address argument of “0”, it will even generate a random MAC address for you.įor more general MAC address spoofing, your MAC address is trivially reset with tools available in default installs of most operating systems. You can spoof a MAC address when using Nmap with nothing more than a -spoof-mac command line option for Nmap itself to hide the true source of Nmap probes. This can be done with a plethora of freely available security tools, including Nmap. People seem to think “Oh, well, sure a determined attacker can get past it, but not anyone else.” It doesn’t take much determination at all to spoof a MAC address. Since that lowest-hanging fruit consists of the majority of wireless access points, MAC filtering can be of value as a way of turning away the majority of opportunistic attackers.ĭon’t rely on MAC filtering alone, however. Its resource consumption is almost unmeasurable, and even if it doesn’t keep out any reasonably knowledgeable security crackers willing to spend a few moments gaining access, it does keep out a lot of automated opportunistic attacks that are aiming solely for the absolute lowest-hanging fruit on the security tree. This doesn’t mean MAC filtering is useless. Anyone who pays any attention to current trends in wireless security at all should know that MAC filtering is less effective than WEP - and that WEP can be cracked almost instantly these days with commonly available tools. MAC address filtering for wireless networking isn’t real “security”.
