Teamer,

first things first, my answer depends on each of your network connections having a separate, static IP address.

The bandwidth you quote for the connections: are they the upstream figures? Bear in mind that as standard (in the UK at least) even a 20Mbps ADSL connection may be limited to as little as 256kb upstream. Which is the important aspect if you are trying to server content.

Also check with your telco's t's & c's as there may be restrictions on hosting content of the connection, possibly with some inbound ports being filtered.

All that said, some solutions....

Simplest solution would be to configure Apache to listen on each IP for each domain as appropriate and set DNS records for each domain. Job done.

I'm assuming that there is some issues with this however. Do you routers pass through public IP addresses or NAT to a private range? Make sure that you get your NATs configured so that external traffic reaches the correct internal IP/service.

If you're using Vista I'd suggest some form of hardware firewall if available, resorting to software f/w at a minimum.

One issue you may face is the default gw settings in Vista. I've had issues in the past trying to dual-home a 2003 server using native windows infrastructure. Not sure if Vista will have the same or similar issues, but if you encounter problems this may be a place to look.

Hope this is of some help.

Thank yo guys , i have som questions left if you don't mind ...

"my answer depends on each of your network connections having a separate, static IP address" < yes every connection has it's own static IP , seperate .

i do not care for the upstream as i need this only to test kinda a big website and i need only 10 users online (at the same time) to test it's functionality and resource consumpsion . plus the development o this site is being done remotly by programmers connected to my laptop .

the current upstream is 6kBps thats one of the reasons why i want to let testers and programmers connect to my laptop through diffirent internet connections , just because having a (6KBps * 3) upstream would be enough .

There are no restrictions (i think) on hosting content because all ports ar open , secondly , am not hosting a content to the public , it's just a private temporary small webserver .

my quesion is : "configure Apache to listen on each IP for each domain as appropriate and set DNS records for each domain" < HOW

and if i am connected to 3 routers with a modem and internet connection for each router through my WiFi card on the laptop ... wouldn't tha be just the same IP ? i don't know , anyway i also need to know how to configure the apache to do it because i use a LAN connetion also :-p

all the routers routs incoming connections from WAN on port 80 to my laptops port 80 (apache) now i am on a single router (don't want to risk and buy 3 others if i can't use them) and it works .


"f you're using Vista I'd suggest some form of hardware firewall if available, resorting to software f/w at a minimum" , i don't need a firewall cuz this webserver will be shutdown when me and the other programmers complete our project .

Thanks RR

BillV thanks for the links ;-) i'll look there i hope it will help me :-) .

"Are you wanting to serve content 24/7? You may significantly decrease the lifetime of your laptop." i believe that we will complete our project in 3 weeks or so , but if i done the 3 connection thing , we will complete it within a week , so no fear on the laptop , anyway i still have another one which is better (linux) , and 3 desktop PCs which can really be used as web servers . :-)

How about port forwarding? Again, this assumes that you have static IPs from your ISP. Something like this:

Router 1      \
Public IP 1    }--  Laptop Prvt IP on Port x
Port 80        /

Router 2      \
Public IP 2    }--  Laptop Prvt IP on Port x + 1
Port 80        /

Router 3      \
Public IP 3    }--  Laptop Prvt IP on Port x + 2
Port 80        /

Of course, you would then have to config Apache to listen for traffic on your chosen assigned port numbers (as opposed to port 80), and also allow those ports through firewalls. Something like 65000, 65001, 65002.

You could also make the argument that this would be additional security albeit through obscurity. No one would be able to connect to your laptop directly through port 80, since there is no listening service on that port. An Nmap scan would reveal it eventually, but since it's not a well-known port, an attacker would have to tell Nmap to look at a larger range of ports. Fun little point.

I think deep down, you already know the answer to this one.

Timing is a funny beast. Did he or anyone from his family contact the univ to inform them of his situation when it happened? It may be too late if he waited too long, but maybe a simple phone call to his instructors/professors or an advisor would be all it would take. Hell move on up to the Dean if he feels like he's not being heard.

If either of you get caught, it will be much worse than the extra semester or year he has to put in.

Don

don friend , he contacted th registration office in the university but it was too late they told him , second some guys did hack and changed 3 or 4 marks without being caught , i wish i could get thier emails or phone# to get thier help ... anyway , i could figure out that they use MsSql and a mail server on the same box as a database server , all i can do now is to do a password generator and let it try to guess the password for user root on ms-sql server (thats if there are a root user) cuz i know that MySQL almost always has a user called "root" don't know about Ms-SQL ... and second i don't know anything about tcp/ip protocol for the MS-SQL server ... i think i'll just use a PC with apachi server installled and make a generator using PHP ... boooring :-s .

they won't catch me i know , iknow also that the network admnistration there is 0 security level and that they have only one engineer to fix the lan cables or the servers if anthing wrong , and he never appears in the university unless there's some problems with the connection or the servers there (acually 1 IIS server and 1 MySQL+Mail server) < i even have more complicated network and powerfull boxes in my home !!! .

I echo RoleReversal's words. This is an ethical site and an EH would not compromise those ethics. We are here to do the right thing, not to just go and change grades to make things easier. Nothing good will come of not doing the work. Take a deep breath and really think about what you want to do before you go and make a costly mistake.

As to the sysadmin not being the smartest security guy around, I think you might be seriously underestimating him. That is a huge mistake. Last thought, is to think your action through. Don't do something to get yourself in hot water. It burns.

Sounds like you've got some good war stories there Kev. We'll have to swap stories over a beer sometime...
