List of Printers at D-MATH
The following color printers and copiers can be accessed from all the ETH computers (incl. using VPN). We strongly recommend to use the “follow me” printer “card-hp“.

How to Protect a Webpage with a Password
Suppose you want to protect the sub-page “secure” of your homepage with a password; that is you want that the visitors are asked for a username and a password when accessing a webpage: Read more
Central Clients of D-MATH
Central Clients are powerful computers in the server room, running Fedora. The software available is the same as on the Linux desktops at the D-MATH. We distinguish between two types of Central Clients: Compute Clients and Load Clients.
Read moreSyncronize your Files with Unison
See also the alternative software FreeFileSync.
Unison is a file-synchronization tool for Linux, Mac and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
SSH Access to D-MATH network from outside
For instance, lets suppose that you want to access the central client ada-18. In this case just start the VPN client and then open a terminal and enter following command:
ssh pytharski.math.ethz.ch -l <eth-username>
Secure File Transfer (SFTP) to the D-MATH network
SFTP can be used on all platforms, incl. Linux, Windows and Mac to transfer files to / from the D-MATH fileservers.
Instructions for each platform can be found here:
- Linux / Mac OS X / Windows (with GUI)
- Mac OS X (with GUI)
- Windows (with GUI)
- Commandline (also Mac OS X and all Unix)
Linux / Mac OS X / Windows
1) Open the application filezilla, if you need to install it you can download it from:
2) With the following information you can connect
- Host: sftp://sftpmath.math.ethz.ch
- Username: [your username]
- Password: [D-MATH password]
3) Click on the button “Quickconnect”
4) You may need to trust the ssh host key of the server to be able to connect
5) Once you are connected you can transfer files from the remote site (right side) to your computer (left side)
Windows
1) One of the SFTP clients for Windows is called WinSCP and can be downloaded here:
2) Open WinSCP and use the following settings under “Basic”, replacing “username” and “password” with your D-MATH details
3) Next we want to save our login details. Under “Stored sessions” click on “save” and enter an appropriate name, e.g. sftpmath. Save with “OK” then click on Login. Next time you use this program just double-click on the stored session name
4) The first time you connect to sftpmath.math.ethz.ch, the security key must be accepted, click Yes here
5) After logging in, your local windows home directory is on the left and your D-MATH home is on the right. To download/upload a file, just double-click it
Mac OS X
1) One of the SFTP-Clients for Mac OS X is called Cyberduck and can be downloaded from cyberduck.io; unzip the file and drag-and-drop Cyberduck into the Applications Folder.
2) Start the application, click on “Open Connection” and enter following information:
Drop-Down Menu: SFTP (SSH File Transfer Protocol) Server : sftpmath.math.ethz.ch Username : your username Password : your password [x] Add to Keychain (<== up to you) More Options: Path : home [ ] Use Public Key Authentiation (<== up to you)
3) Click on “Connect” and then accept the host key fingerprint by also checking the “Always” checkbox.
Commandline
Follow these steps.
1) Open a terminal (xterm, gnome-terminal, …) and
2) Login
name@shell# sftp username@sftpmath.math.ethz.ch
3) On the first login, you will be asked to accept the sftpmath public server key, this should be accepted with “yes” (more about ssh key fingerprints at: ssh-key-fingerprints):
The authenticity of host 'sftpmath (129.132.119.199)' can't be established. RSA key fingerprint is SHA256:o8jYLjJZIkG8+V474HcSdUVJTvSjYOYT3qQi8+8kFtE. Are you sure you want to continue connecting (yes/no)?
then you will be asked for your D-MATH password:
Welcome to the 'sftp'-, 'scp'-, 'rsync'-, 'unison'-, 'svn'- & 'git'-server of the Mathematics Department of ETH Zurich. Your directories: home : your 'home' directory (~) www : your 'www' directory (~/www) ftp : your 'ftp' directory (~/ftp) => ex.: type "cd home". username@sftpmath.ethz.ch's password:
After having logged in you can access your home, ftp and www dirctories. To download a file, use the command “get“. To upload a file from the local directory where you logged in from, use the command “put“.
Following other commands can also be used on the sftpmath server:
cp, ls, mv, rm, scp, help, ...
An alternative to logging in interactively to the sftpmath server and using the above-mentioned sftp commands, is using scp. To download a file abc.zzz from the home directory on sftpmath to a local directory:
name@shell# scp username@sftpmath.math.ethz.ch:/home/abc.zzz .
Don’t forget the “.” at the end of the command which symbolizes the local directory to download to!
To upload a file cba.zzz from the current local directory to the sftpmath home directory:
name@shell# scp cba.zzz username@sftpmath.math.ethz.ch:/home/.
