Linux is installed on classroom PCs in G/N/022, G/N/169, and some department-managed classrooms.

Anyone with an IT Services account can log on to the Linux desktop in classrooms.
Office PCs are restricted to staff and research graduates only.
Ubuntu 14.04 LTS 64-bit is installed as either single or dual boot on classroom PCs (in G/N/022 and G/N/169, also in Departmental Classrooms in collaboration with DCOs), and on the shared teaching0 server.
The service includes core scientific and programming applications, and receives regular security updates.
Departments and research groups may add their own software or resources to the standard build.
We will also consider student requests.

There are a few cases where accounts are not valid on a PC, all of which will give an "Incorrect password" error:
If none of the above apply, contact the Library & IT Help Desk.
The managed desktop is based on 64-bit Ubuntu LTS, for 2014/15 and 2015/16 this is release 14.04.
Our default desktop environment is Gnome 3, identified by their "footprint" icon in the login toolbar:
To change to XFCE 4, click on the icon and change it before you log in:
Classroom PCs default back to Gnome each time.
Your home directory in Linux is the same across all IT Services computers, and is mapped to M: under Windows. You can check how much space is left using the quota -s command in a terminal.
To save temporary files on the local hard disk of a classroom PC, use one of the following locations:
File permissions are set to -rwx------ or 0700
This is a feature of the filer which holds your home directory, unless you actually set permissions on a file it just uses the defaults you're seeing.
If you set permissions using chmod, the filer will assign and keep using Unix permissions. Setting Unix permissions on a directory will also automatically apply Unix permissions to new files created in it.
Some shared drives have native Linux support and are mounted by default. (You may still need to request access from the owner of the share).
Other shares need to be connected manually, such as FlexFS and ProjectFS. Here's an example of mounting a FlexFS drive:
You can check stored passwords using the seahorse utility (Settings | Passwords+Keys from the start menu)
To mount from the command line, use gvfs-mount "smb://ITSYORK;email@example.com/sharename/" - note that the URL needs to match exactly to use your saved password.
To unmount, use gvfs-mount -u "smb://ITSYORK;firstname.lastname@example.org/share/"
To automatically run this command when you login:
We require Kerberos authentication to access all managed Linux systems and filestores. Once you have logged in to one of our systems, your Kerberos ticket allows seamless access to many resources, including SSH.
To set up Kerberos on an unmanaged Linux system on campus (or using VPN access), install the krb5-user package and use the following settings:
Default realm: YORK.AC.UK
Kerberos servers: auth.york.ac.uk auth0.york.ac.uk auth1.york.ac.uk auth2.york.ac.uk
Admin server: authm.york.ac.uk
You can then use the kinit command to get a Kerberos ticket. You'll need to specify the -K option to SSH, or set both GSSAPIAuthentication and GSSAPIDelegateCredentials to yes in your SSH configuration.
Research0 and teaching0 are installed with the 14.04 version of the Linux managed desktop.
YARCC is a research cluster with its own software and access controls, although some of the software is accessible from the managed desktop.
The group its-linux-user-group allows Linux users at the University to collaborate and exchange information. IT Services also make announcements here.
