The SSH Tectia Server daemon program is called sshd2. It can be configured using a configuration file. Command-line options override values specified in the configuration file.
sshd2 and its certificate validation daemon ssh-certd are normally started at boot time from /etc/rc.local or its equivalent. The sshd2 forks a new daemon for each incoming connection. The child processes handle key exchange, encryption, authentication, command execution, and data exchange.
The server daemon is typically run as root. If it is not run as root, only the user the daemon is running as will be authorized to log in, and password authentication may not work if the system uses shadow passwords. An alternative host key pair in user home directory must also be used.
