46 | * LPD "mini-daemon" for CUPS. This program must be used in conjunction | |
47 | * with inetd or another similar program that monitors ports and starts | |
48 | * daemons for each client connection. A typical configuration is: | |
49 | * | |
50 | * printer stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd | |
51 | * | |
52 | * This daemon implements most of RFC 1179 (the unofficial LPD specification) | |
53 | * except for: | |
54 | * | |
55 | * - This daemon does not check to make sure that the source port is | |
56 | * between 721 and 731, since it isn't necessary for proper | |
57 | * functioning and port-based security is no security at all! | |
58 | * | |
59 | * - The "Print any waiting jobs" command is a no-op. | |
60 | * | |
61 | * The LPD-to-IPP mapping is as defined in RFC 2569. The report formats | |
62 | * currently match the Solaris LPD mini-daemon. | |
