---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.

config SLIP_SMART

bool "Keepalive and linefill"
|
||
|
depends on SLIP
|
||
|
---help---
|
||
|
Adds additional capabilities to the SLIP driver to support the
|
||
|
RELCOM line fill and keepalive monitoring. Ideal on poor quality
|
||
|
analogue lines.
|
||
|
|
||
|
config SLIP_MODE_SLIP6
|
||

bool "Six bit SLIP encapsulation"
|

---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.
