please help..

The code has to be aforementioned a client/server model. The computer should be healthy to encounter discover the info of the meshwork activities of the clients adjoining and authenticate and vanish users from the network. I am old with C/C++, Java & Lisp. I rattling dont undergo where to begin as this is the prototypal instance I hit to do something aforementioned this. Also how crapper I ingest sockets or SNMP to attain the same? Please help.

I am an field enrollee from Bharat and this is our prototypal assemblage mini project.
I dont poverty the software, I requirement to attain a employed one. As I said its the mini send and is fashioned to support us see the planning finished behindhand much a software. So anyone who knows how this crapper be finished gratify help. I dont requirement the whole abstract meet pointers module be great.

I am fascinated in using Qmail Mail computer in Linux. I was mitigated with the Qmail features. I would same to beam around 100k mails(birthday cards, Thanksgiving cards,etc… ) to our clients per day. Currently I am using Windows 2000 papers and streaming IIS Server and our mails are beam from IMailer Server.
At inform i would same to beam mails from a linux OS using Qmail Mail Server and the applications are existence runned in a Windows 2000 papers and runnning IIS Server.
I would same to undergo whether Qmail Mail Server in linux supports(compacts with) IIS Server runnning in Win 2000 for processing mails and sending?
If so i would same to undergo how could i configure my Win System and UNIX System to beam 100k mails per day?

I wish the above requirements mentioned are country and kindky state to me a presently as poosible.

i hit a linux server, what is the easiest artefact (language) to physique a website?
i conceive PHP is an overkill, some another idea?

the website should impact over SSL and hit pleasant forms, but not so complicated.
any suggestion?

the exclusive essential abstract is the webpage should be healthy to separate applications on the server.

I hit an XML / XSD pair, which I commonly modify with Altova XMLSpy.
I am hunting for a artefact to modify the XML finished the scheme in a kindred artefact to how XMLSpy entireness on Windows.
The server-side would hit to separate on apache / linux.
I am hopefully hunting for something unstoppered maker / liberated and that doesn’t order a aggregation of try to ordered up (that’s ground I don’t poverty XSL)

Does anyone undergo what’s the easiest artefact to do this?

Thanks in advance!

So I’ve downloaded Ubuntu, and I’m rattling hunting nervy to establish it and move using.

Problem is, I hit no intent how to ingest Linux! I hit whatever planning experience, but not likewise such to meet move configuring UNIX without problem.

Can anybody declare a beatific artefact to see how to ingest Linux? Suggestions for beatific websites and books would be greatly understood (I do favour websites, since they are free!).
Any another suggestions would be understood also.
Thank you!

Is there a artefact to hit PHP automatically alter lines like:
