# Login to the High Performance Computers
The best way to login to the linux machines is via ssh. From a Linux
console, the command syntax is `ssh user@host`. The additional option
\<span>-X\</span>C enables X11 forwarding for graphical applications
(the -C enables compression which usually improves usability in this
case).
The best way to login to the Linux machines is via ssh. From a Linux console, the command syntax is
`ssh user@host`. The additional option `-XC` enables X11 forwarding for graphical applications (the
`-C` enables compression which usually improves usability in this case).
The following table gives an overview of all clusters.

**Attention:** Please use an up-to-date SSH client. The login nodes
accept the following encryption algorithms:
*aes128-ctr,aes192-ctr,aes256-ctr,<aes128-gcm@openssh.com>,<aes256-gcm@openssh.com>,<chacha20-poly1305@openssh.com>,<chacha20-poly1305@openssh.com>*

If your workstation is within the campus network, you can connect to the
HPC login servers directly, e.g., for Taurus:
ssh <zih-login>@taurus.hrsk.tu-dresden.de
```Bash
ssh <zih-login>@taurus.hrsk.tu-dresden.de
```
If you connect for the fist time, the client will ask you to verify the
host by the fingerprint:
