Mon, 16 Feb 2026 15:55:38 +0100

Below you find the recommended configuration for Wi-Fi (WiFi / Wireless / WLAN) and VPN (Virtual Private Network) for members of the D-MATH.

Wi-Fi

General information

The following settings are valid for all members of D-MATH (incl. PhD-Students).
The username to be used is: < your-eth-username>@math-guest.ethz.ch.
The Wi-Fi SSIDs to be used are eduroam , eth or eth-5.
You have to use the Wi-Fi/VPN password and not the LDAP or Active Directory (AD) password.

IMPORTANT: if you are not in the main building (HG) you may also need to start the VPN (see below) to access some D-MATH resources.

SSH Access to D-MATH network from outside

If you are using the D-MATH WiFi or VPN configuration (with “math-guest”), you are already in the D-MATH network and can reach all important hosts directly (e.g., ssh host -l <eth-username>).

If you are using the default ETH VPN (i.e. connected with “staff-net” or “student-net”) you can simply access the D-MATH network (e.g. our central clients) with SSH via pytharski just by entering the following command in a terminal:

ssh pytharski.math.ethz.ch -l <eth-username>
# or just
ssh pytharski -l <eth-username>
# and if your local username is the same as the ETH one, then
ssh pytharski

The first time you log in to pytharski you also have to accept the host key (please verify the fingerprint that you get with this list). Then at the “Hostname or command”-prompt enter for example “ada-29” and you are in:

We explain below what you have to do to be able to work efficiently from your home, for instance how to set up a secure network connection to the ETH Zurich using VPN (eg. to access ETHIS, electronic resources like journals, file shares, …), how to access your e-mails, your files and a virtual linux desktop.

VPN – Secure Network Connection to the ETH

You can set up a secure network connection to the ETH Zurich by connecting to the VPN server using a VPN client. You find all information here:
