MLPPP in kernels 2.2.x w/ PPP v2.4.1

MLPPP in kernels 2.2.x w/ PPP v2.4.1

[Ivan Passos]

Hello, everyone,

The quick question: if I install PPP 2.4.1 in a Linux box w/ kernel 2.2.x,
will I have support to MLPPP??

Now, the explanation for my doubt. I've seen several (actually 3)
different MLPPP implementations for older versions of PPP/pppd (namely
2.3.5 and 2.3.11). I'd like to know if once I install PPP 2.4.1 in a
system w/ kernel 2.2.x, I kill my need for these kind of patches in order
to support MLPPP. Or would I still need some kind of patch, even for PPP
2.4.1, to have MLPPP support in kernels 2.2.x??

I know that for kernels 2.4.x these patches are not needed.

Thanks in advance for your help!

Later,
Ivan

These are excerpts from ppp 2.4.1 README.linux file:


...

The Linux PPP implementation includes both kernel and user-level
parts.  This package contains the user-level part, which consists of
the PPP daemon (pppd) and associated utilities.  In the past this
package has contained updated kernel drivers.  This is no longer
necessary, as the current 2.2 and 2.4 kernel sources contain
up-to-date drivers.               

...

2.1 Kernel driver

Assuming you are running a recent 2.2 or 2.4 (or later) series kernel,
the kernel source code will contain an up-to-date kernel PPP driver.
If the PPP driver was included in your kernel configuration when your
kernel was built, then you only need to install the user-level
programs.  Otherwise you will need to get the source tree for your
kernel version, configure it with PPP included, and recompile.  Most
Linux distribution vendors ship kernels with PPP included in the
configuration.                       

...

Hope this helps,

Koral

Oops, I forgot to add the most important part from README.linux:

...
The 2.2 series kernels contain an older version of the kernel PPP
driver, one which doesn't support multilink.  If you want multilink,
you need to run the latest 2.4 series kernel.  The kernel PPP driver
was completely rewritten for the 2.4 series kernels to support
multilink and to allow it to operate over diverse kinds of
communication medium (the 2.2 driver only operates over serial ports
and devices which look like serial ports, such as pseudo-ttys).
