In HOWTO

--------------------------------------
setp 5. Assuming your files are in /usr/local/src/ and your current working
	directory is also /usr/local/src/ do the following:
		[tar zxvf ppp-2.3.8.tar.gz]
		[gunzip ppp-2.3.8-mppe-others-norc4_TH7.diff.gz] 
		???? is not gunzip.

I followed  PoPToP HOWTO/FAQ and not work properlly with RedHat 6.0 
kernel 2.2.5-15. 

Below are my steps get with many cuts of the your HOWTO/FAQ and others 
e-mails.


I have follow this instructions (step-by-step), if I do any mistakes and 
you can send me I will appreciate!!! 

============================================================================
3.1 Installing MSCHAP/MPPE PPPD Patch
Grab yourself a clean copy of the PPP deamon version 2.3.8 (ppp-2.3.8). 
I usually go here for my PPP files: ftp://cs.anu.edu.au/pub/software/ppp/ 
	 ftp://cs.anu.edu.au/pub/software/ppp/  
	ppp-2.3.8.tar.gz   
	ppp-2.3.8-patch1  {correction IPX...}

Grab youself the MSCHAP/MPPE diff files and the RC4 files Follow these
instructions: 
 MSCHAP/MPPE: http://www.moretonbay.com/vpn/releases/  
	ppp-2.3.8-mppe-others-norc4_TH7.diff
 RC4 files : ftp://ftp.psy.uq.oz.au/pub/Crypto/SSL/
	SSLeay-0.6.6b.tar.gz

[
i.e: host: vpn {example}
]

1. Copy the archives to your local file system [i.e: /usr/local/src/]

[root at vpn src]# ls 
ppp-2.3.8.tar.gz
ppp-2.3.8-mppe-others-norc4_TH7.diff.gz
SSLeay-0.6.6b.tar.gz
[root at vpn src]# tar zxvf ppp-2.3.8.tar.gz
[root at vpn src]# tar zxvf SSLeay-0.6.6b.tar.gz

2. Copy the RC4 files (rc4.h and rc4_enc.c) to ppp-2.3.8/linux/

[root at vpn src]# pwd
/usr/local/src
[root at vpn src]# cd SSLeay-0.6.6b/crypto/rc4/
[root at vpn rc4]# cp rc4.h       /usr/local/src/ppp-2.3.8/linux/
[root at vpn rc4]# cp rc4_enc.c   /usr/local/src/ppp-2.3.8/linux/
	
3. Patch the MSCHAP/MPPE diff file

[root at vpn rc4]# cd /usr/local/src/
[root at vpn src]# cp ppp-2.3.8-patch1  ppp-2.3.8/pppd
[root at vpn src]# cd ppp-2.3.8/pppd
patching file 'sys-linux.c'
[root at vpn pppd]# patch -p1 < ppp-2.3.8-patch1 [pwd]
/usr/src/linux/ppp-2.3.8/pppd 
[root at vpn pppd]# cd /usr/local/src
[root at vpn src]# patch -p0 < ppp-2.3.8-mppe-others-norc4_TH7.diff
patching file 'ppp-2.3.8/...' 
[root at vpn src]# cd ppp-2.3.8

4. The files should now all be in place and we are ready to compile PPP. 
Follow these steps to compile it:

[root at vpn ppp-2.3.8]# ./configure
[root at vpn ppp-2.3.8]# cd linux
[root at vpn linux]# pwd
/usr/local/src/linux/ppp-2.3.8/linux
[root at vpn linux]# ./kinstall.sh
...
Kernel driver files installation done.
[root at vpn linux]# cp * /usr/src/linux/drivers/net/

{ not compile with ´make´ because there isn´t  rc4* files
  then, I did this copy 
}

[root at vpn linux]# cd ..
[root at vpn ppp-2.3.8]# make
[root at vpn ppp-2.3.8]# cd pppd
[root at vpn pppd]# cp pppd /usr/sbin/
[root at vpn pppd]# cd /usr/src/linux
[root at vpn linux]# pwd
/usr/src/linux
[root at vpn linux]# make modules SUBDIRS=drivers/net

------------------------------------------
[ by ppp-2.3.8/README.linux ]

2. Update the kernel sources.
If you are using a kernel earlier than 2.2.8, you can either use the
driver in this package or upgrade your kernel to 2.2.8.  If you choose
to use the driver in this package, you will need a copy of the kernel
source tree to compile the driver.

3. Build the kernel.

now"
