mppe without requiring. Solution how to use mppe-mppc with the recent kernels.

Hello.

I hope you know that the only way to have mppe support optional is to
use mppe-mppc patch from Jan Dubiec. But recent kernels already include
the patch for mppe and thus further patching with Jan's patch fails
but... still possible. To patch you need to remove in-kernel mppe patch.
To do this download mppe patch from the link below:

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.14/2.6.14-mm1/broken-out/ppp_mppe-add-ppp-mppe-encryption-module.patch

And remove patch with `patch -R` command. After that apply Jan's patch
and enjoy :)

I did this with with linux kernel 2.6.17.11. The only small issue I had
was one reject. Code that was added with mppe patch in kernel was not
there anymore, so I ignored that problem.

HTH,
Peter.

James. Can you remove "(note, MAX_CONNECTIONS can't!)" from defaults.h
also?

And I just wanted to forward some fixes from Gentoo land. First of all
segfault using -C option:
http://bugs.gentoo.org/show_bug.cgi?id=132898
and proposed by Alin Nastac (mrness at gentoo.org) patch
(pptpd-1.3.2-connections) in attachment.

And another bug is pptpd syslog flood with GRE packets:
http://bugs.gentoo.org/show_bug.cgi?id=127388

Currently we fix it with the following patch:

diff -Nru pptpd-1.3.2.orig/pptpgre.c pptpd-1.3.2/pptpgre.c

                }
                /* check for out-of-order sequence number */
                if (seq_greater(seq, gre.seq_recv)) {

Done.  Also from the sample pptpd.conf file.  Included in 1.3.3.

Taken.  Also added an informational message to show when the number of
connections has been constrained by the number of IP addresses given.
Included in 1.3.3.

> And another bug is pptpd syslog flood with GRE packets:

Rejected.  Turn off debug mode in pptpd.conf if you don't want to see
these syslog messages.  I see opinions that it should not do this, but I
don't see any good argument.  We have needed these messages to diagnose
problems.

Gladly insane if it helps us support it here.

pptpd-1.3.3 rpmbuild

Wasn't able to release rpm's this time, had a problem:

$ make rpm
fakeroot rpmbuild -ta pptpd-1.3.3.tar.gz
error: Name field must be present in package: (main package)
error: Version field must be present in package: (main package)
error: Release field must be present in package: (main package)
error: Summary field must be present in package: (main package)
error: Group field must be present in package: (main package)
error: License field must be present in package: (main package)
make: *** [rpm] Error 1

Anyone with RPM clue have any idea how to fix?
The spec file is in the tar.gz.

I'm using rpmbuild on Debian GNU/Linux, etch.

James, but could you, please, explain, how GRE sequence number (I mean
"GRE: accepting packet #%d") can help you to diagnose problems?

Thank you,
Peter.

multiple M$ clients accessing POPTOP from same network

Hi,

Is this config possible?

We have a number of employees who currently work off site, we are unable to do a site to site VPN and want to use
the MS PPTP client to connect to the POPTOP server here, it seems that (since we upgraded to 1.32) they now
have intermittent connection problems.

For example 1 user is connected and happily working, another connects and the 1st user disconnects or has no
network response resulting in them having to reconnect.

Regards,

Luke

I take it there is a NATing device between them and the server?

Is the NAT device PPTP aware?

James:

It worked for me without problems on an FC2 machine.  I think your 
problem is specifying "-ta" instead of "-ba".  With "-ta", I get the 
same error messages you did.

Eric.

Most likely

> Is the NAT device PPTP aware?

Will have to check, and post back, but I wonder why they users at the remote site claim that it was working with
the older version of PPTPD?
