Using ssh on iOS or iPadOS

iOS is the operating system for Apple iPhones, and iPadOS is the version for iPads.

With an ssh app, you can get a text login to an Informatics computer from these devices.
The App Store offers a choice of ssh apps. For security, you should choose a highly rated ssh app such as Termius or WebSSH.

VPN

Before you can use ssh, your device will need to be using a VPN - either the University VPN or the School's OpenVPN. The VPN page can help with that.

Self-managed machines in Appleton Tower

To get a self-managed computer on to the wired network in Appleton Tower, please fill in a Support Request. In your message, please include the computer's MAC address, its serial number and its host name. The Computing Support team will tell you when you can connect it to a network port.

A 'self-managed' computer is one that is not managed by the School - so that's anything other than DICE Linux, Windows Managed Desktop, or Managed Mac.

Informatics Forum network ports

Within the Informatics Forum, connections to the wired network are made via network ports which are arranged in sets of six in the various floorboxes situated in both offices and public space. Each user's desk is generally fed from a single floorbox.

To avoid confusion, we configure all floorboxes which feed desks to the following standard pattern with 'port 1' being the lowest-numbered in the box, and 'port 6' the highest:

Connecting from outside the University - an overview

An important aim of the Informatics computing infrastructure is that you should be able to easily and securely use your data, and make use of computing resources, from outside of the School's internal network. To do this, you need to have certain software packages installed on your home computer. Although there are pages on this site telling you how to install this software, they don't necessarily explain what each piece of software does, why you might need them, and how they interact. This page tries to fill that gap.

NTP

We run a local NTP time-synchronisation service for Informatics, and recommend that self-managed machines on our network are set up to use it rather than remote timeservers. There are four machines - ntp0.inf.ed.ac.uk, ntp1.inf.ed.ac.uk, ntp2.inf.ed.ac.uk, and ntp3.inf.ed.ac.uk For robustness you should configure your machine to synchronise to as many of these as your system will allow.

Using ssh from Linux

Most Linux distributions have an SSH client installed by default. For Fedora and Redhat it is in the openssh-clients package; on Debian and Ubuntu it is in the openssh-client package.

Before you can ssh to Informatics, you must be using a VPN - either the University VPN or the School's OpenVPN. The VPN page can help with that.

Then, to access an Informatics SSH server, start a terminal, and enter something like the following (replacing 'yourusername' with your DICE Informatics username):
