Home directories give everyone with a CSE account a finite amount of storage. The amount (and where it is stored) depends on what type of account you have. For information on how to access these folders from various platforms, see the quick links in the upper right.
Your Windows and Linux home directories are one and the same. On Linux, these folders can be reached at /homes/iws/<csenetid>. On Windows, your "Z:" drive is mapped to the same folder via \\tango\<csenetid>. In addition to the Z: on Windows, your Desktop, Downloads, Music, My Documents, My Pictures, and My Videos are stored in your home directory at Z:\WindowsFolders (/homes/iws/<csenetid>/WindowsFolders).
There is a 10GB quota in effect for home directories of undergrads on CSE instructional systems. If your quota is exceeded, you have 7 days to drop below the limit. After 7 days, you are prevented from writing anything until you have deleted enough files to drop below the quota. You will see messages that say "Disc quota exceeded." Enter quota -v on a Linux system to see what your quota is.
If you cannot even log into your Linux account, i.e. your dotfiles are doing something that tries to write a file and causes a fatal error, try the following: Log into your Windows account and use Windows explorer to delete files from Z: until you are below your Linux quota.
Your Windows and Linux home directories are one and the same. On Linux, these folders can be reached at /homes/gws/<csenetid>. On Windows, your "Z:" drive is mapped to the same folder via \\<homeserver>\<csenetid>, where <homeserver> is the file server on which your home directory resides (one of "cash," "companion," or "cube"). Please note that your Desktop, Downloads, Music, My Documents, My Pictures, and My Videos on Windows are NOT stored in your home directory, and are instead stored on your local machine.
There is no hard limit quota.
But realize you share this finite space with all of your colleagues. So while there are no strict quotas being enforced, we ask that folks keep storage in those directories at or below ~30GB. Research project data should be stored in a sponsored /projects share, not in your home directory. Remember that only items stored on Google drive are "forever", so consider using your Google Drive for archiving old projects/work.
Many of our school's computing resources are now on the 172 subnet, which is firewalled at the campus border for security reasons. To connect to these resources from off campus, VPN (virtual private network) software must be installed and running on your computer located off-campus.
The Husky OnNet package is a downloadable application (intended for use on home computers and personal mobile devices) that allows users to remotely access resources that normally require on-campus connections. Detailed Husky OnNet (a.k.a. VPN) service information and instructions can be found on the UW IT Connect pages. Once downloaded and installed the Husky OnNet service must be started; look for an application called “Big IP Edge Client” and start it, and provide your UWNetID credentials for authentication. After authenticating, it will direct traffic to on-campus machines through Husky OnNet (traffic to other destinations will be unaffected).
UW provides the Husky OnNet software free of charge to the UW community, and is available for both Windows and Macintosh hosts.
In the interest of making life easier for everyone, the CSE Lab has developed a software suite, collectively known as GrpAdmin, that allows user-level management of Unix groups and group memberships, either via CLI or web interface.
Remote Desktop Services provides a way to emulate what it is like if you were sitting at a the machine, when you are in fact remote and possibly on a different OS (MacOS / Linux).
Why use Remote Desktop?
- You are sitting at a non-Windows workstation and need some capability only Windows provides.
- You are sitting at a Windows machine and need some capability that is not installed there, but is available via Remote Desktop.
- You are working from home and want the applications or file access of a school computer.
Available Remote Desktop Services
- Your dept. Windows desktop, for users that have one, you can use RDP client to connect to it from anywhere.
- aqua.cs.washington.edu, for faculty, staff, and grads. This is a windows server that provides multiple connections, ideal for those that have Linux or Mac workstations. NOTE: You will not be admin on this machine and files saved locally are not backed up.
- VDI, for anyone in the Allen School. NOTE: These machines are built like undergraduate lab machines, and revert to a predefined state upon restart.
How do I connect?
- If you are using a computer running Microsoft Windows 7 / 8 / 8.1 / 10: Click the start pearl, All Programs -> Accessories -> Remote Desktop connection.
- If you are using a computer running Microsoft Windows XP: Click the start button ->
All Programs -> Accessories -> Communications -> Remote Desktop connection.
- If you are using a computer running MacOS: you will need to install and run the Microsoft Remote Desktop application, available from the App Store.
- If you are using a Linux Based computer: You will need to make sure that a REMOTE DESKTOP client for Linux is installed. We currently install Xfreerdp on department machines but Rdesktop is also known to work. CSE Lab managed linux computers already have xfreerdp. Then you can use xfreerdp --help to choose the settings you would like to use to connect. EXAMPLE: xfreerdp -u joe -d CSENETID vdilab4.cs.washington.edu
NOTE: If you are prompted with a windows logon screen, please specify the DOMAIN name with your credentials. EXAMPLE: CSENETID\bob
Remote Desktop useful tips
- CTRL-ALT-END is the equivalent of CTRL-ALT-DELETE (useful for changing your password).
- If you are connecting from a windows box, hard drives from the client will appear inside the RD session and you can use this to copy files back and forth.
- Newer versions will also install your local printer as a device you can print to from the remote session.
If you are in need of transferring files between you and remote users for your research, but sending or getting them through email or setting your own ftp server would be troublesome, you can use CSE anonymous ftp service. The service is available only to research users.
How it works
The anonymous ftp service at ftp.cs.washington.edu or at URL ftp://ftp.cs.washington.edu allows any Internet user to retrieve and/or deposit files in a specified area without the need to have a CSE account. The ftp user can use a ftp command to access the service with anonymous as the account name, and an email address as its password. A line command such as wget or fetch or a web browser can also be used to access anonymous ftp files by the URL (please see man pages or help facility of individual commands for details.)
On certain well-known CSE systems, such as barb, norfolk, recycle, and tricycle, the ftp directories are accessible via its Unix global path /cse/ftp/, where you can copy files into and out of it. On the other hand, an anonymous ftp user can only transfer files in one direction in each ftp directory. That is a file can be deposited but can not be retrieved and vice versa. This is to prevent our server from being a dumping ground for pirated software and other things to be shared by other anonymous ftp users.
To use the service, there are a couple of self-serve directories that you can use right away for small-size files and for a short duration. They are incoming and outgoing directories for ftp users to deposit and retrieve files respectively. The directories are accessible to CSE users as /cse/ftp/incoming and /cse/ftp/outgoing respectively.
For transferring file to you, tell your user to put file in incoming and you can get the file from /cse/ftp/incoming.
For transferring file to ftp user, you can put your files in /cse/ftp/outgoing. If you are concerned the files might be copied by non-intended ftp users, you might want to protect the files by creating an unbrowsable directory under /cse/ftp/outgoing, and putting the files there.
Once you copy your files into the directory, then you tell your ftp user what the path is. With the example above, the path would be /outgoing/myftp/myfile or URL ftp://ftp.cs.washington.edu/outgoing/toftp/myfile.
You can't remove files that are not owned by you so you can't remove files deposited by a ftp user after you have copied the file. However, you do not need to worry. When the files are older than 5 days, they are automatically removed.
If you need to use ftp on a regular basis such as you have a URL of your project file published in a paper or you have large files or large amount of files that can't be handled comfortably by the server's disk, you can send a request to support@cs.
