Servers
|
||
|
|
=======
|
||
|
|
In this game, a server refers to a computer that can be connected to,
|
||
|
|
accessed, and manipulated through the Terminal. All servers in the
|
||
|
|
game are connected to each other to form a large, global network.
|
||
|
|
To learn about how to navigate this network and connect to other
|
||
|
|
servers, see the :ref:`Terminal` page.
|
||
|
|
|
||
|
|
Server RAM
|
||
|
|
^^^^^^^^^^
|
||
|
|
Perhaps the most important property of a server to make note of is its RAM,
|
||
|
|
which refers to how much memory is available on that machine. RAM is
|
||
|
|
important because it is required to run Scripts. More RAM allows
|
||
|
|
the user to run more powerful and complicated scripts.
|
||
|
|
|
||
|
|
The `free`, `scan-analyze`, and `analyze` Terminal commands
|
||
|
|
can be used to check how much RAM a server has.
|
||
|
|
|
||
|
|
Identifying Servers
|
||
|
|
^^^^^^^^^^^^^^^^^^^
|
||
|
|
A server is identified by two properties: its IP address and its hostname.
|
||
|
|
An IP address is a 32-bit number represented in dot-decimal notation.
|
||
|
|
For example, "56.1.5.0" and "86.5.1.0" might be two IP addresses
|
||
|
|
you see in the game. A hostname is a label assigned to a server.
|
||
|
|
A hostname will usually give you a general idea of what the server
|
||
|
|
is. For example, the company Nova Medical might have a server with
|
||
|
|
the hostname "nova-med".
|
||
|
|
|
||
|
|
Hostnames and IP addresses are unique. This means that if one
|
||
|
|
server has the IP address "1.1.1.1" and the hostname
|
||
|
|
"some-server", then no other server in the game can have that
|
||
|
|
IP address or that hostname.
|
||
|
|
|
||
|
|
There are many :ref:`Netscript Functions <netscriptfunctions>`
|
||
|
|
and :ref:`terminal` commands in the game
|
||
|
|
that will require you to target a specific server. This is done using
|
||
|
|
either the IP address or the hostname of the server.
|
||
|
|
|
||
|
|
Player-owned Servers
|
||
|
|
^^^^^^^^^^^^^^^^^^^^
|
||
|
|
The player starts with a single server: his/her home computer.
|
||
|
|
This server will have the hostname "home." The player's home
|
||
|
|
computer is special for a variety of reasons:
|
||
|
|
|
||
|
|
1. The home computer's RAM can be upgraded. This can be done by visiting
|
||
|
|
certain locations in the World.
|
||
|
|
|
||
|
|
2. The home computer persists through Augmentation Installations. This means
|
||
|
|
that you will not lose any RAM upgrades or Scripts on your
|
||
|
|
home computer when you install Augmentations (you will
|
||
|
|
however, lose programs and messages on your home computer).
|
||
|
|
|
||
|
|
The player can also purchase additional servers. This can be
|
||
|
|
done by visiting certain locations in the World, or it can be
|
||
|
|
done automatically through a script using the :js:func:`purchaseServer`
|
||
|
|
Netscript Function. The advantage of purchased servers is that,
|
||
|
|
in terms of RAM, they are cheaper than upgrading your home
|
||
|
|
computer. The disadvantage is that your purchased servers
|
||
|
|
are lost when you install Augmentations.
|
||
|
|
|
||
|
|
Hackable Servers
|
||
|
|
^^^^^^^^^^^^^^^^
|
||
|
|
Most servers that are not owned by the player can be hacked for money
|
||
|
|
and exp. See the :ref:`gameplay_hacking` page for more details.
|
||
|
|
|
||
|
|
Different servers have different levels of security, but also offer
|
||
|
|
different rewards when being hacked.
