I'm really surprised that this works. After having some looks at
lpd during the past days, I think that an entry with
...:[email protected]:...:if=${PREFIX}/bin/foomatic-rip:...
would cause the raw output of foomatic-rip to be sent over to
1.2.3.4, port 515. And if there's an lpd listening on that receiving
and (1.2.3.4, port 515), I would expect it to log a "bad request
(..) from ..." allmost immediately (or after receiving some bytes)
and closing the connection, causing a SIGPIPE somewhere in foomatic-rip
(or the programs invoked by it). That's what I've seen during my
own tests, and after reading that evil lpd code ;-)
Ciao,
