        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use and BusyBox
        will act like whatever it was invoked as!

いよいよ嫌がらせも極まり。
ま、自前で telnetd を置けばいいだけではあるが。
