---+ Wired Networking

The wired network generally offers better performance and reliability than the various [[WirelessAccess][wireless networks]], and so it is recommended that it be used where possible.  Before a machine can make full use of the wired network, its MAC address must be registered by [[ITManagement#PPE_IT_Support][PPE IT support]].

Linux and Mac OS X users can obtain the MAC address of by using the =ifconfig= command.  The item of interest is usually labelled =HWaddr=, and will appear on a line which looks similar to the following:

<pre>
$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:23:AE:94:B1:1E
</pre>











(See also [[CampusNetwork]] for some wider issues.)

The PPE network has one public subnet and several private subnets. If an unknown machine is connected to a PPE data sockets, it will receive an IP address within the restricted Un-Trusted subnet. Once a machine has been registered with the PPE [[ITManagement]], it will be added to either the Trusted, Laptop or Public subnets depending on the machine type.

No machine should ever be given a static IP address without the prior knowledge and agreement of the [[ITManagement]].

Any machine that is thought to be a risk to the PPE network as a whole will be placed in an un-routed private subnet, and will therefore not be able to send or receive any internet traffic.

---+++ Laptop Subnet

Browsing for Windows shares is not possible from the Laptop subnet, but  users can open Windows shares directly, e.g with <code>Start->Run->\\ppesmb</code>.




---++ Checking a PC's IP Configuration

---+++ Windows
1. Open a command prompt via
<pre>
Start->Run->cmd
</pre>

2. Type
<pre>
ipconfig
</pre>

(<code>ipconfig</code> options can be listed by typing <code>ipconfig /?</code>)

---+++ Linux
1. Open a shell window.
2. Type
<pre>
/sbin/ifconfig
</pre>

(Further information can be found on the <code>ifconfig</code> man page.)
