Banned?

[Ali_Cat]

Apparently, I have a perma ban from 4chan.
I first though it was just something 4chan was doing yesterday. I, along with a few of my friends have been 'randomly daily banned' before, but when my peers were able to get on tonight it had me stumped.

The day(s) of my ban, I didn`t even have acess to a computer. We were up in NM for my grandmothers funeral. It says that the ban had been repealed, and denied (obviously something I didn`t do) Plus the 'reasons for banning' keep changing from spam to post and rate pics.

So it got me wondering, our new huges net box woulden`t have something to do with it? If it belonged to someone previously who was banned.

Anywho,

I`ve already tried disconnecting the modem, and changing my IP adress.
Anyone know how else to get un-banned?
Or will I forever be neglected from lulz.

You can try wiping your browser's cookies. If they IP banned you, changing the IP should have been enough. Try doing both.

yeah you aint getting back on, they dont IP ban or cookie ban you anymore

its more of a GUID assigned to your MAC address of your Router

That doesn't sound right to me. I believe the MAC address of your router will be stripped by the next routing device in the chain. From what I can see there is no historical record in an IP packet of all the MACs for hosts that packet went through. A 3rd party company outside your ISP's network won't get the MAC address of your router in any IP packets delivered to them, just the last routing device that processed the packet.

Even if they did, using a proxy bypass site would defeat that, because the packets the host receives originate from the proxy and contain no network details of the client (assuming they aren't passing on something like Squid's X-Forwardwed-For header, which would defeat the point of a proxy bypass site anyway).

maybe you can access from a different computer?

probably not helpful. sorry :S

Banned from 4chan?

An hero.

They ban the source mac address which would be on your computer..

Replace your nic card and you should be fine

You don't have to replace the nic in your computer, you can usually spoof any MAC you want (I can just change mine in windows under the driver settings, but you can get progs to do this too).

To be honest I don't think its likely they are MAC banning anyway:



it be a pointless way of banning pc clients because its so easily got around.
this isn't technically possible to do from network packets hitting their servers
MAC bans only work for games consoles because the console's own software will retrieve the MAC and send it to the server. For a standard web page this isn't the case, it would have to run additional software with a high privilidge which your browser and security software will bitch at you about, and you could just say 'no' to.

So the only way I can think of them getting your MAC would be there is some software you've allowed to install from 4Chan, and again that can easily be removed or blocked :



take a look in your browser settings (Tools/ Options / Programs ) and remove anything suspicous, and make sure they aren't in your 'trusted sites' security zone in Internet Options so your browser will prompt you if it tries to reinstall.
Another way of would be just to use a different browser (firefox / chrome). If you go firefox, try first installing something like NoScript so you get total control over blocking any naughty things 4chan might try to install.

it uses MAC banning. trust me.

Why yes, your convincing technical argument has totally convinced me :rolleyes:

Care to share how this mechanism works and how the OP can work around it then?

i just happen to be a janitor on there. the whole point of 4chan is to remain anon. hence why i didnt tell you before.

it sends a packet down the connection to your router which then makes the DHCP service tell the 4chan server what NIC is connected to the website.

Once it knows it bans. There isnt a way round apart from getting a new NIC card but, if you connect to the site using the same IP from the new NIC card you will be banned again.

dont question my technical knowledge, after seeing a few threads youve posted on in tech junkies yours isnt to accurate.

whether his technical knowledge is awesome, terrible or both, anyone with any of it - i.e. by your own claims, you - should know that it is entirely possible to spoof mac addresses, and so any security based on that paradigm is questionable at best.

yes i know its spoofable, and that you can flush your IP and recieve a new one from the pool i only explained the basic way it works, those are the two main ways you can be banned from 4chan.

4chan users are both technical and not, as you can tell by some of the banter on there lol, most of them wouldent know how to spoof a MAC address.

there are other things as well but they arnt very good at keeping people out, but if you combine them all together, theres quite a few tasks to do to get back, more than its worth if your banned for a day or two

You *Dont* need a new NIC.

Thats incredibly arrogant, and I'll question anything I please. I've never seen you post any sensible technical detail to explain how I'm wrong so feel more than free to do so anytime, because unlike you I don't get my panties in a bunch when someone fails to bask in my uber geekness, I'm actually keen to learn and help people. I do however feel confident in my understanding of the word "libel".


it sends a packet down the connection to your router which then makes the DHCP service tell the 4chan server what NIC is connected to the website.

I've had a quick scan of RFC2131 (especially section 4.3 describing the server behaviour) and I can't see any mechanism to query a DHCP server to get it to tell you a MAC, so I still don't see evidence to believe this whole MAC blocking thing. I also doubt any DHCP server would be respond to requests to networks it isn't serving as this sounds like opening yourself to a DOS attack. I doubt any router manufacturers would leave their firewalls open on the relevant ports for the same reason. So I can only assume you are in fact talking about an ARP request, but as this doesn't query the DHCP server specifically, your statement didn't make sense to me. As I said in an earlier post ARP will only go as far as your network segment i.e. the next routing device you hit so this wouldn't let you get the client's MAC.

Secondly the DHCP service definately isn't going to know anything about which internal clients are connected to what external services, so you'd only have knowledge of NICS it has current leases for.

So as far as I can see that whole 'find out the client's MAC' thing won't work.

Again - I'm not claiming to have all the answers so if I'm wrong, please don't patronise me, educate me.

After questioning your comparatively elementary technical knowledge, I then continue to mock your arrogance and absolute lack of a grasp for the English language or grammar as a whole. Anyone who thinks they will garnish further respect by advertising themselves as "Microsoft certified" clearly is unknown to any real qualifications or acknowledgement that it is just another way you are paying for Microsoft's executive washroom.

Thank you sir, you have made my day.

My elementary knowledge stretches for beyond what this forum offers, this is a teenage forum where only basic knowledge is needed as the problems here are basic.

the problems i have covered in real life stretch for beyond the realms of IP banning, and getting MS Word 2003 to work.

Hyper-V, Brache-caching and IKEv2 are just some of the many areas i support in my role in the real working world.

As for my grammar? i don't think its too bad being as you can read what im saying, the only time i tend to take extra care is when im producing Technical Documents for clients and staff at my work.

so by all means, call me elementary, i could not give a flying fuck about how much you THINK i know. I know my stuff which is well justified by the generous pay packet i get at the end of the month.

I assume you know what DHCP does? It assigns IP addresses to most devices or hardware that are connected to a network. A server MAY request the MAC address's of the NIC to allow a connection. im sure your familar with MAC filtering. it works on the same principle.

Obviously, a new NIC would give you a new MAC thus bypassing the Banned MAC.

One wouldn't have to have an IQ higher than their shoe size to realise that you're only here to try to look better than everyone else. In actual fact, you still don't seem to be able to do that. Even where only "basic knowledge" is required, you still seem to get that wrong. Hmm...

Congratulations! Your CafePress mug is in the post right now, you can put it right next to your framed picture of your custom built PC on your desk.

I can summarise this sentence with: there are better things in life; you're wasting your time. If you want to show off with words you know I won't understand, then great. It wouldn't take me a minute to Google it and pretend I know what you're talking about, however I don't take much pleasure from trying to make myself look superior to others.

As for my grammar? i don't think its too bad being as you can read what im saying, the only time i tend to take extra care is when im producing Technical Documents for clients and staff at my work.
I think the fact that you, for no reason, capitalised "technical documents" in a sentence where you say that you actually can use grammar says as much as a Shakespearean oxymoron from one of Romeo's speeches.

so by all means, call me elementary, i could not give a flying fuck about how much you THINK i know. I know my stuff which is well justified by the generous pay packet i get at the end of the month.
Ah - you don't care about how much I think you know, then you justify that point by telling me that you know lots. Good to hear!


I'm ending here, I only started to stand up for Paul. I don't think you're worth getting infracted over.

Where does it say that a server may request the MAC address of a NIC? Not in the RFC describing the behaviour of DHCP servers which I quoted. What sort of server, in what network environment? Not one out on the internet talking into a home router from what I can see. Yet again, you've not actually provided technical detail, which would be just smashing, thanks.

You've spent a lot of words making big noises in response to Donkey, can we have some on-topic facts in response to the technical points please? That way I'll learn something, and you can prove how clever you are.


Obviously, a new NIC would give you a new MAC thus bypassing the Banned MAC.

But no one in their right mind would buy a new NIC when you can just spoof it as has been stated so many times now. Really don't know why you keep repeating the same thing.
