  304. PLIP (Parallel Line Internet Protocol) is used to create a

  306. local machines. A PLIP link from a Linux box is a popular means to
  307. install a Linux distribution on a machine which doesn't have a

  309. first). The kernels on both machines need to have this PLIP option
  310. enabled for this to work.
  311. The PLIP driver has two modes, mode 0 and mode 1. The parallel
  312. ports (the connectors at the computers with 25 holes) are connected
  313. with "null printer" or "Turbo Laplink" cables which can transmit 4
  314. bits at a time (mode 0) or with special PLIP cables, to be used on
  315. bidirectional parallel ports only, which can transmit 8 bits at a
  316. time (mode 1); you can find the wiring of these cables in
  317. <file:Documentation/networking/PLIP.txt>. The cables can be up to
  318. 15m long. Mode 0 works also if one of the machines runs DOS/Windows

  320. driver (<http://oak.oakland.edu/simtel.net/msdos/pktdrvr-pre.html>)

  338. otherwise you can't use it; most Internet access providers these
  339. days support PPP rather than SLIP.
  340. To use PPP, you need an additional program called pppd as described
  341. in the PPP-HOWTO, available at
  342. <http://www.tldp.org/docs.html#howto>. Make sure that you have
  343. the version of pppd recommended in <file:Documentation/Changes>.
  344. The PPP option enlarges your kernel by about 16 KB.
  345. There are actually two versions of PPP: the traditional PPP for
  346. asynchronous lines, such as regular analog phone lines, and
  347. synchronous PPP which can be used over digital ISDN lines for
  348. example. If you want to use PPP over phone lines or other
  349. asynchronous serial lines, you need to say Y (or M) here and also to
  350. the next option, "PPP support for async serial ports". For PPP over
  351. synchronous lines, you should say Y (or M) here and to "Support
  352. synchronous PPP", below.
  353. If you said Y to "Version information on all symbols" above, then
  354. you cannot compile the PPP driver into the kernel; you can then only
  355. compile it as a module. To compile this driver as a module, choose M
  356. here. The module will be called ppp_generic.
  357. config PPP_MULTILINK
  358. bool "PPP multilink support (EXPERIMENTAL)"
  359. depends on PPP && EXPERIMENTAL
  360. help
  361. PPP multilink is a protocol (defined in RFC 1990) which allows you
  362. to combine several (logical or physical) lines into one logical PPP
  363. connection, so that you can utilize your full bandwidth.
  364. This has to be supported at the other end as well and you need a
  365. version of the pppd daemon which understands the multilink protocol.
  366. If unsure, say N.
  367. config PPP_FILTER
  368. bool "PPP filtering"
  369. depends on PPP
  370. help
  371. Say Y here if you want to be able to filter the packets passing over
  372. PPP interfaces. This allows you to control which packets count as
  373. activity (i.e. which packets will reset the idle timer or bring up
  374. a demand-dialed link) and which packets are to be dropped entirely.
  375. You need to say Y here if you wish to use the pass-filter and
  376. active-filter options to pppd.
  377. If unsure, say N.
  378. config PPP_ASYNC

  382. ---help---
  383. Say Y (or M) here if you want to be able to use PPP over standard
  384. asynchronous serial ports, such as COM1 or COM2 on a PC. If you use
  385. a modem (not a synchronous or ISDN modem) to contact your ISP, you
  386. need this option.
  387. To compile this driver as a module, choose M here.
  388. If unsure, say Y.
  389. config PPP_SYNC_TTY
  390. tristate "PPP support for sync tty ports"
  391. depends on PPP
  392. help
  393. Say Y (or M) here if you want to be able to use PPP over synchronous
  394. (HDLC) tty devices, such as the SyncLink adapter. These devices
  395. are often used for high-speed leased lines like T1/E1.
  396. To compile this driver as a module, choose M here.

  399. depends on PPP
  400. select ZLIB_INFLATE
  401. select ZLIB_DEFLATE
  402. ---help---
  403. Support for the Deflate compression method for PPP, which uses the
  404. Deflate algorithm (the same algorithm that gzip uses) to compress
  405. each PPP packet before it is sent over the wire. The machine at the
  406. other end of the PPP link (usually your ISP) has to support the
  407. Deflate compression method as well for this to be useful. Even if
  408. they don't support it, it is safe to say Y here.
  409. To compile this driver as a module, choose M here.
  410. config PPP_BSDCOMP
  411. tristate "PPP BSD-Compress compression"
  412. depends on PPP
  413. ---help---
  414. Support for the BSD-Compress compression method for PPP, which uses
  415. the LZW compression method to compress each PPP packet before it is
  416. sent over the wire. The machine at the other end of the PPP link
  417. (usually your ISP) has to support the BSD-Compress compression
  418. method as well for this to be useful. Even if they don't support it,
  419. it is safe to say Y here.
  420. The PPP Deflate compression method ("PPP Deflate compression",
  421. above) is preferable to BSD-Compress, because it compresses better
  422. and is patent-free.
  423. Note that the BSD compression code will always be compiled as a
  424. module; it is called bsd_comp and will show up in the directory
  425. modules once you have said "make modules". If unsure, say N.

  461. Support PPP (Point to Point Protocol) encapsulated in ATM frames.
  462. This implementation does not yet comply with section 8 of RFC2364,

  474. ---help---
  475. Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to
  476. connect to your Internet service provider or to connect to some
  477. other local Unix box or if you want to configure your Linux box as a
  478. Slip/CSlip server for other people to dial in. SLIP (Serial Line
  479. Internet Protocol) is a protocol used to send Internet traffic over
  480. serial connections such as telephone lines or null modem cables;
  481. nowadays, the protocol PPP is more commonly used for this same
  482. purpose.
  483. Normally, your access provider has to support SLIP in order for you
  484. to be able to use it, but there is now a SLIP emulator called SLiRP
  485. around (available from
  486. <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
  487. allows you to use SLIP over a regular dial up shell connection. If
  488. you plan to use SLiRP, make sure to say Y to CSLIP, below. The
  489. NET-3-HOWTO, available from
  490. <http://www.tldp.org/docs.html#howto>, explains how to
  491. configure SLIP. Note that you don't need this option if you just
  492. want to run term (term is a program which gives you almost full
  493. Internet connectivity if you have a regular dial up shell account on
  494. some Internet connected Unix computer. Read
  495. <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP

  502. select SLHC
  503. ---help---
  504. This protocol is faster than SLIP because it uses compression on the
  505. TCP/IP headers (not on the data itself), but it has to be supported
  506. on both ends. Ask your access provider if you are not sure and
  507. answer Y, just in case. You will still be able to use plain SLIP. If
  508. you plan to use SLiRP, the SLIP emulator (available from
  509. <ftp://ibiblio.org/pub/Linux/system/network/serial/>) which
  510. allows you to use SLIP over a regular dial up shell connection, you
  511. definitely want to say Y here. The NET-3-HOWTO, available from
  512. <http://www.tldp.org/docs.html#howto>, explains how to configure
  513. CSLIP. This won't enlarge your kernel.

  529. help
  530. Just occasionally you may need to run IP over hostile serial
  531. networks that don't pass all control characters or are only seven
  532. bit. Saying Y here adds an extra mode you can use with SLIP:
  533. "slip6". In this mode, SLIP will only send normal ASCII symbols over
  534. the serial device. Naturally, this has to be supported at the other
  535. end of the link as well. It's good enough, for example, to run IP
  536. over the async ports of a Camtec JNT Pad. If unsure, say N.
