Hi Ulrich, These lines resemble an attempt to add a line to the /etc/inetd.conf file in order to establish a backdoor. Probably, an attacker's autorooter went awry, thought it had compromised the victim host, and prematurely attempted to upload a backdoor. Nevertheless, I suggest you check whether any of your systems are listening on unusual ports, such as 2222.
