7 | select SLHC | ||
8 | ---help--- | ||
9 | PPP (Point to Point Protocol) is a newer and better SLIP. It serves | ||
10 | the same purpose: sending Internet traffic over telephone (and other | ||
11 | serial) lines. Ask your access provider if they support it, because | ||
12 | otherwise you can't use it; most Internet access providers these | ||
13 | days support PPP rather than SLIP. | ||
14 | |||
15 | To use PPP, you need an additional program called pppd as described | ||
16 | in the PPP-HOWTO, available at | ||
17 | <http://www.tldp.org/docs.html#howto>. Make sure that you have | ||
18 | the version of pppd recommended in <file:Documentation/Changes>. | ||
19 | The PPP option enlarges your kernel by about 16 KB. | ||
20 | |||
21 | There are actually two versions of PPP: the traditional PPP for | ||
22 | asynchronous lines, such as regular analog phone lines, and | ||
23 | synchronous PPP which can be used over digital ISDN lines for | ||
24 | example. If you want to use PPP over phone lines or other | ||
25 | asynchronous serial lines, you need to say Y (or M) here and also to | ||
26 | the next option, "PPP support for async serial ports". For PPP over | ||
27 | synchronous lines, you should say Y (or M) here and to "Support | ||
28 | synchronous PPP", below. | ||
29 | |||
30 | If you said Y to "Version information on all symbols" above, then | ||
31 | you cannot compile the PPP driver into the kernel; you can then only | ||
32 | compile it as a module. To compile this driver as a module, choose M | ||
33 | here. The module will be called ppp_generic. | ||
34 | |||

37 | config PPP_BSDCOMP | ||
38 | tristate "PPP BSD-Compress compression" | ||
39 | depends on PPP | ||
40 | ---help--- | ||
41 | Support for the BSD-Compress compression method for PPP, which uses | ||
42 | the LZW compression method to compress each PPP packet before it is | ||
43 | sent over the wire. The machine at the other end of the PPP link | ||
44 | (usually your ISP) has to support the BSD-Compress compression | ||
45 | method as well for this to be useful. Even if they don't support it, | ||
46 | it is safe to say Y here. | ||
47 | |||
48 | The PPP Deflate compression method ("PPP Deflate compression", | ||
49 | above) is preferable to BSD-Compress, because it compresses better | ||
50 | and is patent-free. | ||
51 | |||
52 | Note that the BSD compression code will always be compiled as a | ||
53 | module; it is called bsd_comp and will show up in the directory | ||
54 | modules once you have said "make modules". If unsure, say N. | ||

60 | select ZLIB_DEFLATE | ||
61 | ---help--- | ||
62 | Support for the Deflate compression method for PPP, which uses the | ||
63 | Deflate algorithm (the same algorithm that gzip uses) to compress | ||
64 | each PPP packet before it is sent over the wire. The machine at the | ||
65 | other end of the PPP link (usually your ISP) has to support the | ||
66 | Deflate compression method as well for this to be useful. Even if | ||
67 | they don't support it, it is safe to say Y here. | ||

71 | config PPP_FILTER | ||
72 | bool "PPP filtering" | ||
73 | depends on PPP | ||
74 | ---help--- | ||
75 | Say Y here if you want to be able to filter the packets passing over | ||
76 | PPP interfaces. This allows you to control which packets count as | ||
77 | activity (i.e. which packets will reset the idle timer or bring up | ||
78 | a demand-dialed link) and which packets are to be dropped entirely. | ||
79 | You need to say Y here if you wish to use the pass-filter and | ||
80 | active-filter options to pppd. | ||

97 | |||
98 | config PPP_MULTILINK | ||
99 | bool "PPP multilink support (EXPERIMENTAL)" | ||
100 | depends on PPP && EXPERIMENTAL | ||
101 | ---help--- | ||
102 | PPP multilink is a protocol (defined in RFC 1990) which allows you | ||
103 | to combine several (logical or physical) lines into one logical PPP | ||
104 | connection, so that you can utilize your full bandwidth. | ||
105 | |||
106 | This has to be supported at the other end as well and you need a | ||
107 | version of the pppd daemon which understands the multilink protocol. | ||
108 | |||

115 | Support PPP (Point to Point Protocol) encapsulated in ATM frames. | ||
116 | This implementation does not yet comply with section 8 of RFC2364, | ||
117 | which can lead to bad results if the ATM peer loses state and | ||
118 | changes its encapsulation unilaterally. | ||

135 | ---help--- | ||
136 | Support for PPP over IPv4.(Point-to-Point Tunneling Protocol) | ||
137 | |||
138 | This driver requires pppd plugin to work in client mode or | ||
139 | modified pptpd (poptop) to work in server mode. | ||
140 | See http://accel-pptp.sourceforge.net/ for information how to | ||
141 | utilize this module. | ||

143 | config PPPOL2TP | ||
144 | tristate "PPP over L2TP (EXPERIMENTAL)" | ||
145 | depends on EXPERIMENTAL && L2TP && PPP | ||
146 | ---help--- | ||
147 | Support for PPP-over-L2TP socket family. L2TP is a protocol | ||
148 | used by ISPs and enterprises to tunnel PPP traffic over UDP | ||
149 | tunnels. L2TP is replacing PPTP for VPN uses. | ||

155 | ---help--- | ||
156 | Say Y (or M) here if you want to be able to use PPP over standard | ||
157 | asynchronous serial ports, such as COM1 or COM2 on a PC. If you use | ||
158 | a modem (not a synchronous or ISDN modem) to contact your ISP, you | ||
159 | need this option. | ||

161 | To compile this driver as a module, choose M here. | ||

169 | Say Y (or M) here if you want to be able to use PPP over synchronous | ||
170 | (HDLC) tty devices, such as the SyncLink adapter. These devices | ||
171 | are often used for high-speed leased lines like T1/E1. | ||
