Setting up a home network for learning Linux

I am working on learning Linux, and somebody suggested setting up Linux on a separate computer, and searching for answers to whatever may be needed, on a different computer plugged in to the Internet.

I have a Windows 7 PC, plugged in to a cable modem, and an old notebook, Compaq Presario R3000 (it was good, but it is already 10 years old, or so). I was thinking about installing the newest CentOS on the notebook (from a CD version), and connecting both machines to the Internet, through an xDSL router (this is what is needed, according to my ISP), which I would get for around $15-$20 (this is what it costs).

My overall goal is to learn server administration. I dont necessarily need to learn Linux as a whole (although I may go in this direction), and it is only the server administration part, which is important. I want to be able to get any UNMANAGED hosting plan (something like dedicated, which may cost $100-$300+ per month) and do everything by myself, on a professional level (administration, maintenence, updates, security, backups), similar to something that I would get with a regular hosting plan (so I want to learn everything, very good).

With this I would have a Linux and a Windows computer, both connected to the Internet, so I could work on the Linux one, and also check whatever would be needed, through the Windows one.

With this, I was wondering, if I could set up actual server on the Linux computer (LAMP, lets say), and start experimenting with hosting some websites there. I am not sure if the router would be what is needed for this, and how would this work. Router will computer both computers to the Internet, but will it connect them to each other, probably not...

I would like to be able to have both of the machines turn on, have websites on the Linux machine, and be able to access them from the Windows PC, lets say. This way I could experiment with it, just like I could with a regular hosting plan on the Internet.

So, the question is, is it possible not only to have two separate machines connected to the Internet, but also have these machines connected to each other, and work like I would work with a regular Linux server, on the Internet.

Thanks.

CHRONY(1)							   User's Manual							 CHRONY(1)

NAME

       chrony - programs for keeping computer clocks accurate

SYNOPSIS

       chronyc [OPTIONS]

       chronyd [OPTIONS]

DESCRIPTION

       chrony  is a pair of programs for keeping computer clocks accurate.  chronyd is a background (daemon) program and chronyc is a command-line
       interface to it. Time reference sources for chronyd can be RFC1305 NTP servers, human (via keyboard and chronyc), or the  computer's  real-
       time  clock at boot time (Linux only). chronyd can determine the rate at which the computer gains or loses time and compensate for it while
       no external reference is present. Its use of NTP servers can be switched on and off (through  chronyc)  to  support  computers  with  dial-
       up/intermittent access to the Internet, and it can also act as an RFC1305-compatible NTP server.

USAGE

       chronyc	is  a command-line interface program which can be used to monitor chronyd's performance and to change various operating parameters
       whilst it is running.

       chronyd's main function is to obtain measurements of the true (UTC) time from one of several sources, and correct the system clock  accord-
       ingly.  It also works out the rate at which the system clock gains or loses time and uses this information to keep it accurate between mea-
       surements from the reference.

       The reference time can be derived from either Network Time Protocol  (NTP)  servers,  reference	clocks,  or  wristwatch-and-keyboard  (via
       chronyc).  The main source of information about the Network Time Protocol is http://www.eecis.udel.edu/~ntp.

       It is designed so that it can work on computers which only have intermittent access to reference sources, for example computers which use a
       dial-up account to access the Internet.	Of course, it will work on computers with permanent connections too.

       In addition, for Linux 2.0.x (for x >= 32) or 2.2 onwards, chronyd can monitor the system's real time clock performance, so the system  can
       maintain accurate time even across reboots.

       Typical accuracies available between 2 machines are

       On  an ethernet LAN : 100-200 microseconds, often much better On a V32bis dial-up modem connection : 10's of milliseconds (from one session
       to the next)

       With a good reference clock the accuracy can reach one microsecond.

       chronyd can also operate as an RFC1305-compatible NTP server and peer.
