    Well, given that lpd has been a chronic source of problems, I think the
    best you can do is limit access to lpd to trusted machines, where you
    trust the operators of those computers to use your lpd properly. If you
    have a hostile environment, I wouldn't suggest using lpd.

    However, if it is feasible for you to restrict access to lpd to trusted
    hosts, you can configure lpd to accept connections only from those hosts
    using the lpd.conf file (see the lpd.conf(5) manpage) and host-based
    firewalls (iptables for linux kernel 2.4.x, I think).
