config [31mCONFIG_PPP[0m
tristate "PPP (point-to-point protocol) support"
select [31mCONFIG_SLHC[0m
---help---
[31mCONFIG_PPP[0m (Point to Point Protocol) is a newer and better [31mCONFIG_SLIP[0m. It serves
the same purpose: sending Internet traffic over telephone (and other
serial) lines. Ask your access provider if they support it, because
otherwise you can't use it; most Internet access providers these
days support [31mCONFIG_PPP[0m rather than [31mCONFIG_SLIP[0m.
To use [31mCONFIG_PPP[0m, you need an additional program called pppd as described
in the [31mCONFIG_PPP[0m-HOWTO, available at
<http://www.tldp.org/docs.html#howto>. Make sure that you have
the version of pppd recommended in <file:Documentation/Changes>.
The [31mCONFIG_PPP[0m option enlarges your kernel by about 16 KB.
There are actually two versions of [31mCONFIG_PPP[0m: the traditional [31mCONFIG_PPP[0m for
asynchronous lines, such as regular analog phone lines, and
synchronous [31mCONFIG_PPP[0m which can be used over digital [31mCONFIG_ISDN[0m lines for
example. If you want to use [31mCONFIG_PPP[0m over phone lines or other
asynchronous serial lines, you need to say Y (or [31mCONFIG_M[0m) here and also to
the next option, "PPP support for async serial ports". For [31mCONFIG_PPP[0m over
synchronous lines, you should say Y (or [31mCONFIG_M[0m) here and to "Support
synchronous PPP", below.
If you said Y to "Version information on all symbols" above, then
you cannot compile the [31mCONFIG_PPP[0m driver into the kernel; you can then only
compile it as a module. To compile this driver as a module, choose [31mCONFIG_M[0m
here. The module will be called ppp_generic.
if [31mCONFIG_PPP[0m
config [31mCONFIG_PPP_BSDCOMP[0m
tristate "PPP BSD-Compress compression"
depends on [31mCONFIG_PPP[0m
---help---
Support for the BSD-Compress compression method for [31mCONFIG_PPP[0m, which uses
the LZW compression method to compress each [31mCONFIG_PPP[0m packet before it is
sent over the wire. The machine at the other end of the [31mCONFIG_PPP[0m link
(usually your ISP) has to support the BSD-Compress compression
method as well for this to be useful. Even if they don't support it,
it is safe to say Y here.
The [31mCONFIG_PPP[0m Deflate compression method ("PPP Deflate compression",
above) is preferable to BSD-Compress, because it compresses better
and is patent-free.
Note that the BSD compression code will always be compiled as a
module; it is called bsd_comp and will show up in the directory
modules once you have said "make modules". If unsure, say N.
config [31mCONFIG_PPP_DEFLATE[0m
tristate "PPP Deflate compression"
depends on [31mCONFIG_PPP[0m
select [31mCONFIG_ZLIB_INFLATE[0m
select [31mCONFIG_ZLIB_DEFLATE[0m
---help---
Support for the Deflate compression method for [31mCONFIG_PPP[0m, which uses the
Deflate algorithm (the same algorithm that gzip uses) to compress
each [31mCONFIG_PPP[0m packet before it is sent over the wire. The machine at the
other end of the [31mCONFIG_PPP[0m link (usually your ISP) has to support the
Deflate compression method as well for this to be useful. Even if
they don't support it, it is safe to say Y here.
To compile this driver as a module, choose [31mCONFIG_M[0m here.
config [31mCONFIG_PPP_FILTER[0m
bool "PPP filtering"
depends on [31mCONFIG_PPP[0m
---help---
Say Y here if you want to be able to filter the packets passing over
[31mCONFIG_PPP[0m interfaces. This allows you to control which packets count as
activity (i.e. which packets will reset the idle timer or bring up
a demand-dialed link) and which packets are to be dropped entirely.
You need to say Y here if you wish to use the pass-filter and
active-filter options to pppd.
If unsure, say N.
config [31mCONFIG_PPP_MPPE[0m
tristate "PPP MPPE compression (encryption)"
depends on [31mCONFIG_PPP[0m
select [31mCONFIG_CRYPTO[0m
select [31mCONFIG_CRYPTO_SHA1[0m
select [31mCONFIG_CRYPTO_ARC4[0m
select [31mCONFIG_CRYPTO_ECB[0m
---help---
Support for the MPPE Encryption protocol, as employed by the
Microsoft Point-to-Point Tunneling Protocol.
See http://pptpclient.sourceforge.net/ for information on
configuring [31mCONFIG_PPTP[0m clients and servers to utilize this method.
config [31mCONFIG_PPP_MULTILINK[0m
bool "PPP multilink support"
depends on [31mCONFIG_PPP[0m
---help---
[31mCONFIG_PPP[0m multilink is a protocol (defined in RFC 1990) which allows you
to combine several (logical or physical) lines into one logical [31mCONFIG_PPP[0m
connection, so that you can utilize your full bandwidth.
This has to be supported at the other end as well and you need a
version of the pppd daemon which understands the multilink protocol.
If unsure, say N.
config [31mCONFIG_PPPOATM[0m
tristate "PPP over ATM"
depends on [31mCONFIG_ATM[0m && [31mCONFIG_PPP[0m
---help---
Support [31mCONFIG_PPP[0m (Point to Point Protocol) encapsulated in [31mCONFIG_ATM[0m frames.
This implementation does not yet comply with section 8 of RFC2364,
which can lead to bad results if the [31mCONFIG_ATM[0m peer loses state and
changes its encapsulation unilaterally.
config [31mCONFIG_PPPOE[0m
tristate "PPP over Ethernet"
depends on [31mCONFIG_PPP[0m
---help---
Support for [31mCONFIG_PPP[0m over Ethernet.
This driver requires the latest version of pppd from the CVS
repository at cvs.samba.org. Alternatively, see the
RoaringPenguin package (<http://www.roaringpenguin.com/pppoe>)
which contains instruction on how to use this driver (under
the heading "Kernel mode PPPoE").
config [31mCONFIG_PPTP[0m
tristate "PPP over IPv4 (PPTP)"
depends on [31mCONFIG_PPP[0m && [31mCONFIG_NET_IPGRE_DEMUX[0m
---help---
Support for [31mCONFIG_PPP[0m over IPv4.(Point-to-Point Tunneling Protocol)
This driver requires pppd plugin to work in client mode or
modified pptpd (poptop) to work in server mode.
See http://accel-pptp.sourceforge.net/ for information how to
utilize this module.
config [31mCONFIG_PPPOL2TP[0m
tristate "PPP over L2TP"
depends on [31mCONFIG_L2TP[0m && [31mCONFIG_PPP[0m
---help---
Support for [31mCONFIG_PPP[0m-over-[31mCONFIG_L2TP[0m socket family. [31mCONFIG_L2TP[0m is a protocol
used by ISPs and enterprises to tunnel [31mCONFIG_PPP[0m traffic over UDP
tunnels. [31mCONFIG_L2TP[0m is replacing [31mCONFIG_PPTP[0m for VPN uses.
if [31mCONFIG_TTY[0m
config [31mCONFIG_PPP_ASYNC[0m
tristate "PPP support for async serial ports"
depends on [31mCONFIG_PPP[0m
select [31mCONFIG_CRC_CCITT[0m
---help---
Say Y (or [31mCONFIG_M[0m) here if you want to be able to use [31mCONFIG_PPP[0m over standard
asynchronous serial ports, such as COM1 or COM2 on a PC. If you use
a modem (not a synchronous or [31mCONFIG_ISDN[0m modem) to contact your ISP, you
need this option.
To compile this driver as a module, choose [31mCONFIG_M[0m here.
If unsure, say Y.
config [31mCONFIG_PPP_SYNC_TTY[0m
tristate "PPP support for sync tty ports"
depends on [31mCONFIG_PPP[0m
---help---
Say Y (or [31mCONFIG_M[0m) here if you want to be able to use [31mCONFIG_PPP[0m over synchronous
([31mCONFIG_HDLC[0m) tty devices, such as the SyncLink adapter. These devices
are often used for high-speed leased lines like T1/[31mCONFIG_E1[0m.
To compile this driver as a module, choose [31mCONFIG_M[0m here.
