help |

Say Y if you intend to use SLIP or CSLIP (compressed SLIP) to |
|
connect to your Internet service provider or to connect to some |
|
other local Unix box or if you want to configure your Linux box as a |
|
Slip/CSlip server for other people to dial in. SLIP (Serial Line |
|
Internet Protocol) is a protocol used to send Internet traffic over |
|
serial connections such as telephone lines or null modem cables; |
|
nowadays, the protocol PPP is more commonly used for this same |
|
purpose. |
|
|
|
Normally, your access provider has to support SLIP in order for you |
|
to be able to use it, but there is now a SLIP emulator called SLiRP |
|
around (available from |
|
<ftp://ibiblio.org/pub/Linux/system/network/serial/>) which |
|
allows you to use SLIP over a regular dial up shell connection. If |
|
you plan to use SLiRP, make sure to say Y to CSLIP, below. The |
|
NET-3-HOWTO, available from |
|
<http://www.tldp.org/docs.html#howto>, explains how to |
|
configure SLIP. Note that you don't need this option if you just |
|
want to run term (term is a program which gives you almost full |
|
Internet connectivity if you have a regular dial up shell account on |
|
some Internet connected Unix computer. Read |
|
<http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>). SLIP |
|
support will enlarge your kernel by about 4 KB. If unsure, say N. |
|
|
|
To compile this driver as a module, choose M here. The module |
|
will be called slip. |

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

Adds additional capabilities to the SLIP driver to support the |
|
RELCOM line fill and keepalive monitoring. Ideal on poor quality |
|
analogue lines. |

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