Fwd: Re: Networking in Africa...
i don't know if I've ever actually received 1 of those spam messages from a host inside Nigeria wow, i seem to get several per day. would you like some, i can setup an exploder for some of my spam if anyones interested? ;) and they're all actually sent/relayed through a host in Nigeria? my first few were, none that I received after that were. alot from south africa, and a few other parts, but no more from Nigeria Interestingly enough, I got the following today from a Cybercafe in Nigeria that I had blocked: Thanks for the prompt response to the problem with our IP address. I have alreday instructed all staff to be more vigilant and we are going through the list of people who came around that time on saturday to track down who sent this email. I am in the process of buying a cybercafe management software which allows the administrator to look at diffrent PCs and see what people are doing so that if we spot things like this we will stop it. Furthermore, I have instructed my team to program the webcams to take snapshot of the shop every 20 minutes so that we can see who was in the shop at what time. I have also made sure we have notices put up in the cafe to say we do not tolerate email spamming and anybody caught will be reported to the autorities for appropriate action However, I must stress that this is a cybercafe where 100% of people who come there use web based email and there is no software or mechanism to stop spamming from web based emails. You can see from the mail that was sent that the person put a web based email address as the return address. Therefore I cannot guarantee that this will not happen again , I can only put measures in place to deter people. If there is any software you know about that would prevent this or mechanism please let me know and I will put it in place immediately I am surprised however that there is no responsibility placed on providers of web based emails who are in the best position to filter out and prevent such emails from being delivered. I hope all the measures highlighted above will be enough for you to go to the ISP to reactivate our blocked IP cheers Adeyinka So what exactly do people do in regards to Web spam? I block tcp/80 but would like to hear what others are doing. Regards, Hank

Re: Networking in Africa...
Try finding some IP connectivity while in Nigeria. You would be hard-pressed, even if you are willing to pay enormous $$. I get lots and lots and lots of spam from cybercafes located in Nigeria, as well as apologies from both the cafes and the upstream networks. I realize this doesn't fit with your preconceptions, so I'll drop it here. Be sure not to look at http://directory.google.com/Top/Regional/Africa/Nigeria/Business_and_Economy/Internet/ or you might learn about at least ten ISPs operating in Nigeria. *yawn* Have you ever been in Lagos?

Re: Networking in Africa...
Try finding some IP connectivity while in Nigeria. do tell us your personal experience and when it was. The most recent? Lagos, Sep 2002. Alex
Re: Networking in Africa...
The most recent? Lagos, Sep 2002. africa is quite large. lagos constitutes but a small portion of it.

So what exactly do people do in regards to Web spam? I block tcp/80 but would like to hear what others are doing. Block or rate limit? I would assume that blocking port 80 in a cybercafe wouldn't really work out in the long run. One possible solution might be to force all traffic through a proxy, and have it cache all outgoing form traffic for several weeks. This way, if someone reports abuse, you can search the cache and find out who is doing it. From there, hopefully you'll have enough information to hand it over to law enforcement, or at least ban the customer from the cafe. I don't know what (if any) legal right of privacy is in Nigeria, but I would suspect that a publicly posted policy notice (like management reserves the right to monitor all traffic and a strict TOS policy) should mitigate any legal concerns about doing this. The only problems I see with this are hard drive space for the cache, and the possibility of spammers using secure web sites. Do any web-mail sites use https these days? -- David
Re: Networking in Africa...
but I am being told that Lagos is the center of Africa by such knowledgeble persons who claim that there are *gasp* thousands *gasp* of cyber-cafe's in Lagos. I mean since there no thousands cyber-cafe's in the entire US, I am sure presence of thousands of them in a rather small city means it is *the* center. a cybercafe != the centre of a continent! wake up. there are many cyber-cafe's in south africa too. sometimes as many as 12 in a single street. but i'd not call south africa the centre of a continent just because of it. each country is different. each country brings with it it's own regulatory framework, incumbent telco of varying degrees, etc. judging any continent on a single country is extremely closed-minded.

Fascinating. Nigeria now has not only US-like internet penetration but also a US-like legal system. I would suggest that those who never stepped a foot in the sub-Saharan Africa refrain from describing how the internet access is setup there. Alex
Re: Networking in Africa...
may be africa is different, but in other developing countries (central asia, south america) cybercafes substitute personal PC access. No one goes to cybercafes in the us since an average middle class family can afford a computer and typically has a phone line. elsewhere, people pool resources to get a 64 kbps line and a bank of six to eight pcs on a lan. people use cybercafes in the same fashion they used pcs here -- i have seen cybercafes set up in shanty towns. - Original Message - From: [EMAIL PROTECTED] To: fingers [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Tuesday, December 03, 2002 10:35 AM Subject: Re: Networking in Africa...

My experience has been that it is illegal in most countries and generally considered unethical to intercept the communications of third parties without their knowledge. Notifying people that you reserve the right to intercept their communications does not provide them with the knowledge that their communications are being intercepted. Knowing that your communications might be intercepted or that someone has the right to intercept them is not the same as knowing that they *are* being intercepted. If you want to do this, your notification has to be explicit. I suggest, You have no privacy here. Everything you are doing is being logged. Notice that when you tell people the truth, it starts looking less like what you wanted to do in the first place. I think it's obvious that a wishy-washy mangement reserves the right to monitor all traffic is an attempt to deceive your customers. I strongly recommend not doing that. DS
Networking in Africa...
Hello, A friend of mine is working on one of the committees for next years Supercomputing conference and noticed that, in the past, they'd had participants from most continents but none from Africa. Does anyone know of a good organization/group/etc which we could spam with our conference notice and request for participation? Thanks! Eric :) PS: For those who are curious, here's part of the write-up for the SC Global portion of next years Supercomputing conference: SC Global is the multi-national and multi-cultural meeting place for communication and discussion of ideas relating to high-end computing and communications and their impact on science and society. SC Global 2003 will be the second time we've held such an event; we have the opportunity to build on the successes of SC Global 2001, and to learn from its challenges. SC Global will include several Showcase events featuring art, music, dance, and other innovative uses of advanced collaboration technologies. In addition, SC Global will be an important extension of SC 2003's high-quality technical program. For example, papers presented in SC Global will meet the same high standards as those in the regular Technical Papers sessions.

One thing to keep in mind is that people that reside in Africa are large/huge prepaid GSM users. Take that and apply it to mobile data services over cell phones (3G and the likes) and I think you lend yourselves to interesting things. Doing bluetooth or IR to your desktop/laptop from your phone to get 128k+ speeds where there is no wired infrastructure but cellular will do interesting things to transform internet usage in these places and others that have skipped the wired telephony phase of development. Take that in conjunction with the talks at nanog about ipv6, pigs and rockets strapped on and you will start to see some of the most interesting developments yet in the internet. - Jared -- Jared Mauch | pgp key available via finger from [EMAIL PROTECTED] clue++; | http://puck.nether.net/~jared/ My statements are only mine.
