HPE Hawk access
Access
The only way to access the HPE Hawk (frontend/login nodes) from outside HWW net is through ssh.
Information on how to set up ssh can be found on our webserver at Secure Shell (ssh).
The SSH public key fingerprints are:
| Type | Fingerprint |
|---|---|
| ECDSA | SHA256:e9baVVjIcaztKSdn30R0Gk5xrta/WP9scQ1GsLsrWC4 |
| ED25519 | SHA256:832zq3DA5JvYvo39piPXqqt3SA77VjuvF26e8c25d28 |
| RSA | SHA256:4u+wl6y+ylXxZHjDYt35S9aRk7SMx8U8xc4Jp+NYonk |
Usage
There are several frontend/login nodes available, access is available using:
- hawk.hww.hlrs.de
or by seelecting one specific server:
- hawk-login03.hww.hlrs.de
- hawk-login04.hww.hlrs.de
- hawk-login05.hww.hlrs.de
The frontend nodes are intended as single point of access to the entire system. Here you can set your environment, move your data, edit and compile your programs and create batch scripts. If doing so might require an increased number of resources (compiling, creating tarballs of dozens of MBs or more, copying a large amount of data, etc.), please prefix "nice -+19" to the respective command in order to keep the login node responsive for other users! Interactive usage like run your program which leads to a high load is NOT allowed on the frontend/login nodes.
The compute nodes:
- r1?c?t?n?
for running parallel jobs are only available through the Batch system !
TOTP
We are currently preparing the optional protection of ssh access with a time-based One-Time-Password (TOTP). As soon as the TOTP functionality has been set up, we will announce this accordingly. On login nodes, each user can decide for himself whether access should be secured via TOTP. In order to be able to use TOTP, a secret must be created. For this we have provided a tool "generate_2fa_otp.sh". It prints out a secret QR code which needs to be scanned by your cell phone TOTP app or saved into another TOTP-end device like a USB NitroKey. The generated private secret will be activated by the system the following day.
