The password in the HNI corresponds to that of the IMT. It can only be changed via the web mask of the IMT user administration.

The SecureShell SSH supports public key authentication. This requires a pair of keys: a private and a public key. This is done with the ssh-keygen programme. Attention: When asked for a passphrase for the private key, you must not enter anything if you want to work completely without entering a password.

The keys are stored in the .ssh2 directory in the home directory. Two more files must now be created there: the identity and the authorisation. The content should be as follows:

odenbach@robin[~/.ssh2]>>ls -l
total 8
-rw-r--r-- 1 odenbach gurus 22 Sep 26 14:58 authorisation
drwx------ 2 odenbach gurus 1024 Oct 16 11:48 hostkeys
-rw------- 1 odenbach gurus 1392 Sep 26 14:57 id_dsa_2048_a
-rw-r--r-- 1 odenbach gurus 1260 Sep 26 14:57 id_dsa_2048_a.pu
-rw-r--r-- 1 odenbach gurus 20 Sep 26 14:58 identification
-rw------- 1 odenbach sct 512 Oct 16 15:42 random_seed
odenbach@robin[~/.ssh2]>>cat identification
IdKey id_dsa_2048_a
odenbach@robin[~/.ssh2]>>cat authorisation
Key id_dsa_2048_a.pub

It is also important that your own home directory has at least the rights 701 so that the SSH server can also read the authorisation file.
