wakeonlan

Wake on LAN packets need to be sent to the default VLAN, which can be done by broadcasting to the subnet 10.11/16. i.e.

wakeonlan -i 10.15.255.255 ab:cd:ef:01:23:45

This can be done from the Physics SSH gateway, ssh.physics.ox.ac.uk

Introduction to transferring files between systems

The file-transfer utilities rsync and unison have one very useful feature in common: If a file already exists at the destination end, only the differences are actually copied. In particular, if the files are the same, nothing gets transferred. This is most obviously useful when updating a massive set of files over a slow network, but is also a great timesaver if the transfer is interrupted part of the way through (restart to resume), or if the source fileset may have changed while we were copying it across.

VPN Services

The University runs a campus wide VPN service and it is recommended that you use this in preference to the physics department service. If this has any issues for you, please contact IT support who will advise on possible other solutions.

Help on the campus VPN service is here.The campus system requires you to load additional software on your client but this allows a secure service to be provided on a wider range of clients than the Physics department service.

Recommended procedures for connecting systems to the cable network

The following procedures should be followed when connecting equipment to the Physics cable network. This is necessary to prevent disruption to other users from configuration problems on the equipment being connected.

The recommendations below are for equipment which will be more or less continuously connected to the network.

How to obtain your MAC address on your laptop

A MAC address is a unique number assigned to network cards by the manufacturer. Every hardware network card comes with its own MAC address. MAC addresses have the format 00:0F:A7:B5:57:7E. The Physics Network will only allow computers with known MAC addresses to communicate.

How to Obtain Your MAC Address

Note: all of these commands will return multiple results if you should have multiple network cards installed (e.g. if you have a wireless network card in your laptop). The first result listed should generally be the correct one for registration.

Connecting a system to the Physics cable (non-wireless) network

If you would like to register a system on the cable/wired network, you will need a Physics Networking Account. This account can be used to access the online cable registration form.

NB. Departmentally supplied and configured systems will already have been registered when you receive them.

Connecting to the Physics VPN using the Windows operating system

A Virtual Private Network (VPN) is a way of extending our internal network out to systems connected on the internet. Once connected via a VPN, a remote system appears to be connected locally to our network thereby getting all the facilities available to local users and avoiding blocks placed in intervening firewalls. All data passed via a VPN is encrypted.

Information on viruses and the virus protection used in the department.

As viruses become more prevalent its now imperative to have virus scanning software installed on your Windows desktop systems. OUCS have both Sophos and F-PROT Professional which can be purchased from the OUCS shop for the price of the media, but seeing the software is updated at monthly intervals we have an alternative, a Sophos server, which is updated every night with any intermediate updates direct from Sophos.

Please visit our Sophos Page for more details.

Overview on the Networking Services, what they cover and how to get in contact.

The Network Services group develops and installs the computer network within all the Physics buildings. We are also responsible for the electronic door locking some aspects of the telephone network.

We will usually supply all components up to and including the cable from the computer to the wall. A basic 100Mbit/s connection is provided by default although the case for 1000Mbit/s backbones and server connections will be considered and a decision made based on the loading of the existing network. Anyone requiring additional facilities will be expected to contribute to the cost.
