    (This has nothing to do with linux-kernel, sorry...)

    I don't think anything particular in that message suggests he actually got
    rooted? It just seems that somebody tried to exploit lprNG hole (or
    something else) and the daemon logged that. Of course, it *is* perfectly
    possible, that he _got_ rooted (although he said he was running redhat-7.0
    with all the updates).

    (The attacker may have tried other attacks so if he got rooted, those above
    are not necessarily the related log messages. In any case, a 'smart' intruder
    would have cleaned the log. Also, 'smart' attacker propably uses something
    more advanced as backdoor than /etc/inetd.conf these days.)

    Or is there something that actually indicates a succesfull intrusion in the
    log snippet that I'm missing?
