Can you ban someone permanently if

Im on another forum where theres always the same guy that keeps comming back over and over again spamming the forums and the best the mods can do is ban the user. Since this person is on a proxy they cannot ban his IP.

I was just wondering if anyone knew of a way of permanently banning this person.

do you log on at this forum? If so just ban his id.

How big is your community there? If it is large enough, try
implementing a 7 day waiting period before you are allowed to
post. Sure it will cut down on the number of new people, but
nobody is seriously going to wait 7 days just to spam and get banned
and wait another 7 days. Depending on what kind of forum it is,
this can work very well.

I beg to differ. Such has happened in the past 'round these parts.
I'm kind of an ignoramus when it comes to this stuff, but is it possible to ban his MAC address? that ought to be a unique key that not just anybody knows how to change...

You can't change it without changing
the card (unless you're a hardware genius and has working knowledge
of the card).

And yes, I believe you can ban MAC addresses on
servers. Not sure about specific sites.

I say enable email authenticacion and ban by email adress, yes, he can re-register an email, but its a waste of time.

I've had to change the MAC address on my router since my ISP didn't like it. It was no big deal and I didn't have to change the hardware, there are utilities out there for just this purpose.

How to ban Spammers: Kill them.

Banning MAC addresses is a very effective method, since most computer users don't even know they exist. Many who DO know they exist only know so because they have to have thiers to get thier computer online at thier college. Yet they still may not know what they are and how to change them. Banning MAC addresses can be done with a software called Steel Belted Radius.

The simple solution to this is what I do: just make deleting and banning him quicker (and easier) than the registration process.

First of all, make registering require an e-mail address to activate your account. When he signs up, ban his account (and hence that e-mail address), so that if he wants to come back he has to go through the lengthy process of setting up a new e-mail address, and re-registering on the site. If he does, BAM! kill him again (i.e. have a button that deletes a user and all their posts/topics/PMs etc.) at the touch of a button. Eventually they'll give up.

I like it! Lep and his mighty KILL BUTTON!

That's what I always thought too, but I had friends at school who were changing their MAC adress because there was a bug in the school network that had banned theirs by mistake. (don't ask)

The red button of doom. That would be a good idea. Or slaping the user. Each time a "slapped" user posts something, his post would be replaced with an annoying message like "Swearing will hurt my dainty little ears!" or "I have cavities the size of bus-stops.". Feeling annoyed, they will have to leave. And the board users could have some fun, too.

Well, as no one noticed, I was implying
the ban of his Ethernet card's MAC address not a router. A router
acts completely different, but that doesn't seem to
stop people from flying off the handle into ape-s**t
infinity.

You can change all sorts of crap with a
router, it doesn't mean it changes your personal Ethernet card's MAC
address.

At PSU if you walk around campus and with your laptop
on, if you have a wireless card it will continually try to connect to
servers. Since there's so many on campus after, I think, 15 or so
attempts it will alert the Admins. They'll think someone is trying to
"hack" their systems. Because it could be a generator
program that goes to each server trying every possible password.

I'm sorry if this post doesn't make much sense. I've been woken up early

How many of those do you have lep?

* tentatively raises hand*
at least one.

Jon even the big red button cant keep you away from this place :smile:

I thought a MAC address on a NIC was internal (to its own network), as its information is removed when it gets routed and such.

MAC addresses are just there for
hardware registration. (and I'm not sure what you're
asking/saying)

I know on private servers (such as wireless
ISPs on campuses) you have to register your MAC address so the server
will allow you network access. It's just a hardware "signature"
if you want to think of it that way. But this is on a physical
Ethernet card, not an entire network or a router or anything funked
up like that.

No, I know what you're talking about...but I take networking and so far
as I know the MAC address of a specific NIC shouldn't be available
across the internet as that address would have been replaced by the
last router or switch to carry the data through. So it would make sense
in an internal network to have MAC filtering, but I'm saying it
shouldn't work over the internet as you wouldn't have access to the MAC
address of that other computer.

yeh as soon as the data leaves the router and gets to its destination the reply would first look the the address of the router(s) and then when it got into the network it would look specifically for the NIC's MAC address (at leat I can remember something from taking the CCNA carnt remember much else and thak god I didnt have to pay for it)

i think you guys just know when to turn a topic so it makes my heard ache to read it.

goes and lies down

As networking is my job in the real world I think i can explain MAC addresses to some folks who may not understand and may have some questions.

MAC addresses are like a permanent IP address for every network device that is made. It is stored in EPROM (Eraseable and Programmable Read Only Memory) they only really started being used effectively in the first days of switches as opposed to hubs. I think we all probably know what a hub is, It's that thing we plug into at LAN parties. hubs communicate with computers by broadcasting requested information to ALL network devices that are connected to it. (That is how a packet sniffer works, It gathers this broadcasted info as the hub is putting it out) Switches, on the other hand, keep a table of all MAC addresses connected to it and which port they're connected to, therefore switches get the requested data and send it ONLY to the computer or other device that requested it.

Modems are no different than network cards other than they are slower because they work on a single-pair long-distance line that is often sent over t1 repeaters (this is what makes them slow). when your modem connects to an ISP you are actually calling another modem on the other end of the line. The group of modems available is called a modem pool. The other modem's serial port connects it to a router which acts like a switch that keeps a table with your MAC address and which modem in the pool your data should go through. When the router sends information from your PC, It also accompanies it with your IP address and MAC address and other information such as IP port and client name.

Any server that you connect to acts as a switch also that keeps your IP and MAC addresses in a table to send your data to you. If the server blocks your MAC address, you are no longer able to access said server. Each router and switch and modem has a MAC address as well, so if a server blocked your ROUTER's MAC address then all computers and devices connected to it would likewise be blocked.

I could never form the words. But yeah, that's basically the idea I had about the situation (and in general).

you're quite right then. Any other questions about such things i'd be glad to answer.

I do not think it is possible for a website to block a MAC address.

WC, if his spamming is becoming too much and getting indecent and all
that, contact the admin of the proxy he uses. They generally don't like
anyone abusing their system and they'll block his IP/account.

If it's not that serious do what Lep said.

f**kin' Macs.

f**kin' Macs.

Except the hardware is excellent ...
the software is ... lacking, to put it softly.

If you find a way to contact his ISP they often don't take kindly to
others disrupting others' service...it's usually in their TOS. So he
could be warned or banned.
