[pptp-server] SuSE 7.0 2.2.16 PPP 2.3.11 PPTP 1.1.2 w MPPE and compression patc h -- ERROR tty_pushing ...

[Philip Van Baren]

The versions in the kernel are indeed newer than those in ppp 2.3.11, which
is why the kinstall.sh script refuses to overwrite them.  The newer version
should be used.

The tty_pushing error message can be fixed by patching the if_ppp.h and/or
if_pppvar.h header files, as described in the FAQ
(www.vibres.com/pptpd/pptpd-FAQ.txt):


7.4 Errors while building pppd, pptpd, and kernel modules

7.4.1.	Get PPP_VERSION or PPP_MAGIC undefined error message while compiling
ppp kernel modules

	Solution: add the following lines to /usr/src/linux/include/linux/if_ppp.h
		#define PPP_VERSION "2.3.11"
		#define PPP_MAGIC   0x5002  /* Magic value for the ppp structure */

7.4.2.	Get "structure has no member named `tty_pushing'" error messages
while compiling ppp kernel modules

	This is probably because the mppe patches you used were for an older
version
	of the kernel, and the ppp structure in the header file if_pppvar.h changed
	in the version of the kernel you have.

	Solution: apply the patch
http://www.vibrationresearch.com/pptpd/if_ppp_2.2.17.diff
		to the kernel sources.
