# me: rwxr-xr-x root root /etc/ssh/login-notify.sh

sender="root@$(hostname)"
recepient="root"

[ "$PAM_TYPE" = "open_session" ] || exit 0
{
	echo "SSH login auf $(hostname)"
	echo "User: $PAM_USER"
	echo "Ruser: $PAM_RUSER"
	echo "Rhost: $PAM_RHOST"
	echo "Service: $PAM_SERVICE"
	echo "TTY: $PAM_TTY"
	echo "Date: $(date)"
	echo "Server: $(uname -a)"
	echo "finger:"
	echo "$(finger)"
	echo "----------------------"
} | tee -a /var/log/my_logins.log | mail -r "$sender" -s "SSH login auf $(hostname)" "$recepient"

add at the end of /etc/pam.d/sshd:
