[pptp-server] pppd 2.4.1 kernel 2.4.5 and this dumb stupid p pp_mppe.o

Hello Joe,

I won't be able to offer extended help on this, T-4 hours to an extended
vacation ;)  My information is also limited to RedHat distributions, I don't
know if it applies to Caldera or not.  But I do have some comments that
should point you in the right direction.  First off, you won't get a ppp.o.
What you should get is a slhc.o, ppp_generic.o, and ppp_mppe.o.  These
should be located in /lib/modules/ <kernel version> /kernel/drivers/net.  If
you have the first two, you are on the right track.  Also, as far as not
having ppp_mppe.o, this is exclusive to the kernel build, and has nothing to
do with the ppp build.  So continue to troubleshoot your kernel, don't worry
about ppp or pptpd yet.  Ok, now here is what I did to get this part
working.

First, I grabbed the 2.4.7 kernel from www.kernel.org.  The 2.4.5 kernel
should work just as well though.  Once you have untared and unzipped, or un
b-zipped the kernel, obtain the linux-2.4.0-openssl-0.9.6-mppe.patch.gz
patch.  I don't recall off hand where I got it, but a google search should
point you in the right direction.  From the /usr/src/linux directory (or
where-ever you de-compressed your kernel source) type 

gcat <path to patch>/linux-2.4.0-openssl-0.9.6-mppe.patch.gz | patch -p1

If you get any errors, don't proceed, you need to troubleshoot why you got
the errors.  Assuming you didn't, start your make process.  I use make
menuconfig, but make config and make xconfig work just as well.

In the Code maturity level options section, mine looks like this:
[*] Prompt for development and/or incomplete code/drivers

In the Network Device Support section, mine looks like this:
<M> PPP (point-to-point protocol) support     <-- THIS IS NECESSARY
[*]   PPP multilink support (EXPERIMENTAL)
<M>   PPP support for async serial ports      <-- THIS IS NECESSARY
<M>   PPP support for sync tty ports
<M>   PPP Deflate compression                 <-- THIS IS NECESSARY
<M>   PPP BSD-Compress compression            <-- THIS IS NECESSARY
<M>   PPP over Ethernet (EXPERIMENTAL)
 
Ok, exit out (after you check your other kernel options) and run these
commands:
make clean
make dep
make bzImage
make install
depmod -a               <-- I never bothered to figure out where I should do
this, so I do it twice.
make modules
make modules_install
depmod -a

If you run into any errors, troubleshoot those before you move on to the
next line.
At this point, reboot, and you should have a ppp_mppe.o listed in
/lib/modules/ <kernel version> /kernel/drivers/net


Good luck,

I am currently trying to get this going. I re-comiled my 2.4 kernel (I don't
know the minor revision because it is whatever Cadera 3.1 version comes
installed)  And I don't have a ppp.o or a ppp_mppe.o file after I do a
make dep, make clean, make modules SUBDIRS=drivers/net.

Next to PPP (point-topoint protocol) support, I have a <M> so it builds it
as a module. As far as the 'monolithically' goes, I don't know anything
about that. There has to be something that I am missing because I can't seem
to build ppp.o or ppp_mppe.o. Please help!
