Login using Strudel
Authentication:
--- Background Information ---
Strudel communicates with remote sites via multiple Secure Shells (SSH).
It is mandatory that the remote site trusts Strudel and is 100% sure
that the incoming connection is by a certain user and no none else.
Hence, each new SSH connections starts with an authentification procedure.
SSH supports different authentification methods, but not all are available on any site.
Strudel uses the most secure Public-Key Authentification (PKA) as it is supported by all sites.
PKA is based on a SSH key-pair with a private key and a public key.
The private key never leaves the local machine and the public key must be installed on the remote machine.
Anyone who knows the private key can now connect to the remote machine.
Hence, the private key is in general encrypted with a passphrase for security reasons.
But it is not desirable to involve the user in each of the multiple authentification procedures.
Hence, Strudel relys on an SSH key agent on the local machine.
A SSH key agent loads private keys and ask for the passphrase once.
For a new SSH connection the SSH key agent can now provide the private key without user interaction.
--- Important ---
How this SSH key agent is started and what private keys are loaded depends on you:
- load your key to a SSH key agent (ssh-add on Linux or OSX or Putty's Pagent on Windows) before you start Strudel
- choose "Remember me" as Authentication Option in Strudel
Configuration:
If you use the vanilla package from MASSIVE or the JURECA configuration is missing
