The key pair used for server authentication is defined on the server in the
sshd2_config file with the following parameters:
HostkeyFile hostkey PublicHostKeyFile hostkey.pub
During the setup process, one RSA key pair (with the file names
hostkey.pub) is generated and stored in the
/opt/tectia/etc/ directory. By default this key pair is used for server authentication. Make sure that only the user running
sshd2 has access to the private key.
By default, the server uses a public key with the filename of the private key plus the extension
PublicHostKeyFile keyword has to be defined only if the public-key file is stored with a different filename.
