I have no idea exactly how to do it, as I have never even heard of a smoothwall firewall but I would like to caution you.
The thing is that as soon as you stumble upon the unlucky coincidence of changing to the same mac address as one of your fellow internet users who happens to be on the same router as you both will get a very bad connection and your ISP will notice that one of you two is doing something bad as alarm bells should start ringing on their monitoring systems. Now these are low level errors and might not be monitored but the can be and they are very easy to detect and even easier to find out which of the two users is messing about trying to hide. If you are looking to escape a tap setup on your connection use encryption for all important stuff PGP is more than good enough. Taps are setup on the basis of an IP not a MAC and as such it will do you no good to change the MAC. Try setting up a SSH connection to any random machine, then tunnel from there to the union ring and you are pretty safe from any tapping as all data coming out is going out using SSH (unreadable even for the state) and then jumps on a purpose build network that hides your true identity even from the sites you are browsing. I happen to know all of this as I have been working for a major ISP for about 5 years and I have been closely working with the security department of this ISP to setup taps and to ensure that the IP of the unlucky victim would not change for as long as the legal paper work would allow this person to be tapped. Hope this helps you a bit, Rob ps, I am not against tapping as such I just don't states that are to idle. On 9/21/06, Ian Macdonald <[EMAIL PROTECTED]> wrote:
Dear All, First I would like to say hello to all in the community Next I would ask for some advice, I wish to change the MAC address of my smoothwall, firewall every 24 hours, I can do it manually, but would prefer it to be a cron job and perl seems ideal. You may well ask why I wish to do such a thing, well we dont all live in a free and open country, VoIP is a grey area here and changing the MAC keeps me covered. OK I hear you all say thats not going to help, but trust me, the more insular a country is the less sophisticated it is in the way it takes away ones rights. Anyway all help appreciated All the best Ian -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
