Becoming a webhost?

Hey, I was wondering how you do this. I have a fast cable connection, 20 gigs of free space. How would one go around learning how to become a web host?

Even if it is only for me, and get about 500 visitors a day? No downloads either. Why then would cable be so bad?

What I'm saying is, can you make your PC into a server?

Too slow...Trust me, for a site as big as yours, you should have at least a t1.

you don't have to...just have your computer on 24/7

There are a few ways to handle the IP address changes. One way is to use dyndns with a program called directupdate...supported on unix, win32, vms, and mac. When your ip changes, it will change your dyndns name as well. Just alias your dyndns name with a CNAME on the dns to you domain name and you'll be ok.

Do the same with your DNS file with your MX and CNAME records for your mail server, and you can run a mail server just as well dynamically. If your IP should ever change while mail is delivered, it will be redelivered to the host name...which will retranslate to your new IP if the mail package is rejected and resent by a relay/email server.

there are a few ways to grab a static ip with cox and time warner, nut i'm sure the mods will pull my post if i discuss them...the web just isn't what it used to be...hope the above is helpful!

www.dns2go.com that should get you started
how about hosting a multiple domain name? You may use it if you will host 1 domain only.. hmm, u still need a static ip for name servers.. web have a webhost.

500/per day=21/per hour=1 per 3 min let's say each visitor stays on average 6 minutes. Since he has cable he is probably on 128kb upstream which gives each user on average a 64kb bandwidth. That is very good considering that most users will be on dial up using 10kbps at the most.

[Let's try this again..]

1) Pre-ramble

Hi,

I've been sitting on this for a while debating morally
weither or not I should post it. After being lied to by multiple
cable internet companies, told that I'm stupid by cable modem
vendors, and having my access turned off for complaining about
broken DNS i've decided that it's time to post.

2) legal stuff

This is theft of service, you will be probably get caught, don't
do it if you value your cable internet service.

This document is only to be redistributed/copied with the original
text included (including credit to myself).

3) explanation

Companies are out to make money, they hire people with book knowledge,
and stupid things like this happen. (Hi AT&T, your DNS is _still_ broken
even after it was fixed for 2 weeks)

Basicly it's a simple ARP caching thing, it's easy to fix in the modems
and somewhat easy to obscure at the ISP. I'm sure *someone* must have
done this besides me, but from all my searches on the web I've seen
nothing but 'it's impossible' messages, the only people I know that
can do it are people I showed how. I'm sure i'm going to upset those
people by posting this, oh well.

4) Let's get started

Cable modems known to work with this:
3Com Sharkfin (all models)
Motorola (all models)
Toshiba PCX1100
Cisco (?)

Modems that probably don't work:
RCA DCM235
3Com CMX (USR)


First, you need the following:
An operating system with
1) A tftp server,
2) snmp software (I used ucd-snmp),
3) a DOCSIS config file generator such as this one:
http://docsis.sourceforge.net/

5) Go go go.

a) determine the address of the modems TFTP server, some modems
are nice enough to give this info to you on their web interface,
others via SNMP, i've been told that a lot of providers use the
same address as their DHCP servers. Most modems use 192.168.100.1
as their interface address, try to snmpwalk it with the coax
disconnected after rebooting (some retain their config information,
but reset the community strings). (AT&T/MediaOne has 'public'
enabled for the ro string.. go from there)

b) determine the name of the configuration file, use the same methods
as above, or see below if you're running a semi intelligent tftp server.

You need to generate a DOCSIS config file for your modem to use, read
the documentation and examples from the docsis config file program
mentioned above.

c) set the address of your chosen machine to the address of the
tftp server, start pinging the address of the cable modem
(192.168.100.1 usually), this will cause the modem to put
you in its arp tables when you reboot it (reboot it now)

d) the modem will (hopefully) connect to your machine and start
(trying) to download the configuration file, if you couldn't determine
what it was named earlier this is where the smart tftp server comes in,
it should tell you what file name the modem attempted to grab.

e) You're done, easy wasn't it?
