Re: N900 PPTP VPN with MPPE
 

Hi all,

I followed all information in this threat and managed to get a VPN connection. I have one chalange left: after connecting to the VPN I need to use a proxy server for my browser. Do you have any hints on how to set this up automatically, after connecting to the VPN?

Thanks in advance,

Bas

Re: N900 PPTP VPN with MPPE
 

@ Big Phat Jan,

Thanks mate, you are great, but i m lost @ some stage

I did upto commenting the sub, and after that i do not know what to do

the only info i have abt my VPN connection is
it is PPTP, servername and credentials

Say my server name is : vpn.servername.com
usn: tom
pass: 123

how do i create a conf file and where do i place it and how do i make a tunnel

Thanks in advance

Re: N900 PPTP VPN with MPPE
 

I wish I knew how to play around with linux. Isn't there a gui or client for PPTP VPN for n00bs like me?

Re: N900 PPTP VPN with MPPE
 

Hi Tom,

It's a while since I set mine up, but I think you need to use:

pptpsetup --create tunnelname --server vpn.servername.com --username tom --password 123 --encrypt

If you have been given a domain you can add "--domain domainname\\".

The point of pptpsetup is to create your configuration files, one of which will be /etc/ppp/peers/tunnelname if you want to check the script has run ok.

That done you can use the pppd command I gave in the post on page 2 and follow the instructions from there. Let us know how it goes!

Cheers,
Jan

Re: N900 PPTP VPN with MPPE
 

I'm afraid not. You could try voting in the brainstorm here, and voting for the bug here, though that has been closed as "moved to brainstorm".

The closest I can find is from wrayb in this thread though I haven't tried it myself, and it sounds like it's only a little bit easier than following the instructions here.

Cheers,
Jan

Re: N900 PPTP VPN with MPPE
 

Thanks Jan really appreciate your help dude.

Will check it out from home. N900 is sweet and PPTP extensibility will be sugar sweet. I wonder if there are any paid apps for PPTP VPN.

Re: N900 PPTP VPN with MPPE
 

Well it looks like you don't have the right credentials ("no auth is possible").

Check the contents of the following files and see whether your username, domain, and password are correct:

/etc/ppp/chap-secrets
/etc/ppp/peers/<tunnelname>

If you have a domain, make sure your username comes out as:

DOMAIN\\username

(with two slashes).

You'll need to be root to check the contents of these files. The easiest way to check them is to use "cat", which will print the contents of the file to the screen, i.e.

#become root
sudo gainroot

#check contents of chap-secrets
cat /etc/ppp/chap-secrets

#check contents of peers file
cat /etc/ppp/peers/<tunnelname>

#stop being root
exit

Cheers,
Jan

Re: N900 PPTP VPN with MPPE
 

Thank you guys so much for creating this thread and sharing this information.

I am having some difficulties as well. I think I'm 90% of the way there, but I'm stumped at the moment.

I looked in the error log file in /var/log and it was empty. I have scoured the net and found a good resource here:

http://pptpclient.sourceforge.net/howto-diagnosis.phtml


here is an excert from my dbug output:

How to step by step
 

Hi everyone,

Since now we have the Kernel Power including PPTP issues, could someone give us a step by step to setup PPTP VPN?

I´m a beginner and at this moment I feel lost doing that. :confused:

I now it´s a matter of time to having a APP to make the things realy easy like "Mobile HotStpot" (in my oppinion the most usefull!)

Re: How to step by step
 

Sounds like a great idea! It would be more then sweet if someone with the right brains and knowledge could explain how we use this new inbuilt kernel support. I need PPTP VPN to connect to my company network (and terminal server). Would be AWSOME if someone could get this to work (and make my N900 so much more usefull).

Thx in advance :)

Re: N900 PPTP VPN with MPPE
 

I got pptp working with 3g, details here.

Re: N900 PPTP VPN with MPPE
 

Hi,

When i try to insmod the files i get "Invalid module format"
do i need to recompile them on my device?
Its the same for all modules

EG:

Re: N900 PPTP VPN with MPPE
 

they need to match with your kernel.

those modules seems to be compiled against the default kernel module from nokia

if you are overclocking, you surely has installed the kernel-power from extras (also called titan kernel) and

1) the modules doesnt match with kernel-power, thats why they gives you an error
2) those modules are already compiled in the kernel, so you dont need to do anything about that, you can safely skip the insmod instructions

its you are not overclocking, install the kernel-power from extras. it does not overclock by default and also have the modules automatically applied.

Re: N900 PPTP VPN with MPPE
 

ah cool its working now i must have already had them.

now just need to sort the routing out. Any pointers for that?

Re: N900 PPTP VPN with MPPE
 

Cool i can vpn and ping the inside devices.

The last thing even tho its a small thing, is:

when i connect to the vpn it pushes all external data over that connection. Is there a way to automaticaly set it to only push that subnet over that vpn and the rest over my default gateway.

can i just change the line in /ett/ppp/peers/<profile> so it does it on connection?
change the "default route" to the correct route?

if not then i'll have to be content with just disconnecting vpn to direct connect from my local gateway.

cheers

and big thank you to Big Phat Jan for the run through!

Re: N900 PPTP VPN with MPPE
 

Hi,

I am trying to setup my PPTP tunnel based on the step-by-step instructions, but I stucked at the beginning with the dpkg commands. I cannot install the pptp and ppp packages to my N900 downloaded from fanoush home page.
Does anyone have an idea, what can be missing? Seems only I have this problem.

Here is the error message I get:

Also I have a second question, if the first is solved: how shall I set up the pptpsetup parameters if my VPN server doesn't support encryption? Is it enough if I don't give --encrypt parameter or something else is necessary too?

Thanks for your help!

cheers

Re: N900 PPTP VPN with MPPE

Re: N900 PPTP VPN with MPPE
 

I'm a n00b linux users trying to setup the pptp vpn. I have a problem:

When I try to install the: linux_1.7.2-1_armel.deb
my n900 App Manager says : unable to install ppp-linux incompatible application package

trying to install: ppp_2.4.4rel-8osso4_armel.deb
I get App Manager : Operation failed

I updated to the power kernel, but no idea what's I'm doing wrong..
Can anyone help?

Thanks

Re: N900 PPTP VPN with MPPE
 

Hi all,

I am not much of a linux user myself and I'm getting the same error as gykiss when i do dpkg -i ppp_2.4.4rel-osso4_armel.deb

How do I continue on from here?

Re: N900 PPTP VPN with MPPE
 

hi all...

i wanna connect to my office vpn, i can usually do this using my winxp notebook, create connection using the new connection wizard, then edit my registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\RasMan\Parameters\ProhibitIpSec to 1

i've tried to connect using my n900 from vpnc but it wasn't successful, is there any chance that this client works for my office vpn setting?

Re: N900 PPTP VPN with MPPE
 

i install

pptp-linux 1.7.2-1
ppp 2.4.4rel-8osso4
modules-2.6.28-20094102-pptp.tar.gz

i start pppd and this ends with Segmentation fault
can you help me?

Re: N900 PPTP VPN with MPPE
 

i have this problem too !!!

Re: N900 PPTP VPN with MPPE
 

try installing ppp first, then pptp ;)
and don't forget root

Re: N900 PPTP VPN with MPPE
 

I'm using the powerkernel. But when i try to install the other packages it just says incompatible? any updates on the subject in general or is this the way its done?

Re: N900 PPTP VPN with MPPE
 

I think that the kernel modules are already present in the power kernel (you probably still need to insmod them).

I'm not going to have time to test this out until after Christmas though.

Cheers,
Jan

Re: N900 PPTP VPN with MPPE
 

hi
i was following the instructions and got to the step where to delete the bit of code (without deleting i am getting also a message that it didnot work, but not one being that weird; going on i get this message (of course, i did it several times (deleting and trying) but the message did not really change):

my hope is that a) i am too stupid to read or b) bigphatjohn made a mistake everybody is correcting except me (of course of linuxskills i haven't got)

so a big thanks! for every one trying to help me!

Re: N900 PPTP VPN with MPPE
 

It does work with the power kernel. As Jan said, the kernel modules are already present in the power kernel but you still need to insmod them (This also means that you do not need download or extract the modules package). See Jan's post on page 2 but use :

instead of the insmod section in those instructions. Note that the only change is the modules directory.
Hope this is some kind of helpful.

Re: N900 PPTP VPN with MPPE
 

I'm not sure, but from the error message it looks like you've uncommented something you shouldn't have in the pptpsetup script near line 234. I haven't tried setting this up since PR1.3 so I can't say for sure. I will go through the process myself soon and will see if anything else suggests itself.

Cheers,
Jan

Re: N900 PPTP VPN with MPPE
 

Hi,

Recently i received an upgrade for my ppp package (most probably from devel repository) to version 2.4.5-2. The update went fine, but seems this package doesn't support "replacedefaultroute" parameter. The vpn is established, but without modifying the default route it is practically useless and doing it manually is also not really acceptable for me. At the end i went back to Fanoush' original version.
Anybody else has the same experience with this new package or do you know the new parameter, which does the same job? (Or simply shall i follow the generic rule "do not upgrade if it is working finel"? :-) )

Re: N900 PPTP VPN with MPPE
 

a gui please :(

Re: N900 PPTP VPN with MPPE
 

Hi
What is this error???
CAn Someone Make GUI or .sh file?
Thanks

Re: N900 PPTP VPN with MPPE
 

Thanks to all for the very useful instructions and hints that have been posted in this thread and without which I'd never have got a working VPN.

I got the routing to work (to have all traffic go over the VPN) by:

1) creating the directory /etc/ppp/ip-up.d

2) creating a file in this directory with the content:
(Note that the filename must not have any extension or it won't be executed.)

3) chmod +x this file

That's it!

From tests of running the PPTP VPN over a gprs0 connection, the VPN connection doesn't seem reliable in that after a while it disconnects. It might be due to inactivity timers but then I would have thought the 'persist' option would automatically reconnect. For this reason, it looks like it's best to launch the vpn in a terminal window with
pppd call <tunnelname> logfd 2 nodetach debug dump
so that one can easily check if it's still up.

Update:

On Wifi it's rock solid, however to get the routing working (again to have all the traffic go over the VPN) you need to add another line to the script:

Update 2:

For some unknown reason my N900 decided to show 'missing image' when booting up after having run out of juice. A reflash of the system didn't help, a reflash of the eMMC did. Unfortunately this meant that I lost all the changed I had made including setting up a vpn connection. In this new attempt, the system behaved somewhat differently.

First, I could not get pptp to launch a scrip in /etc/ppp/ip-up.d/ I tried changing the permissions, made sure that the script name had only alphanumerical characters (plus hyphen and underscore). Nothing would do.

Eventually I found it would run a script at /etc/ppp/ip-up so I created one. Here are my two scripts:

/etc/ppp/ip-up
/etc/ppp/ip-up.d/000defaultroute
(this includes some unnecessary but useful debugging info.)

For some reason, the DNS didn't seem to work even though I do have usepeerdns as an option and the debug info displayed by the launch of the pppd call shows that pppd got the right DNS info from my vpn server. /etc/ppp/resolv.conf was set to this values. /etc/resolv.conf however had just one entry set to localhost. By changing resolv.conf to
At that point, it all worked! If you don't want to use nameservers that work on any network then you may need to change this file in ip-up and restore it in ip-down.

(Like the first time, the vpn connection is not stable when on 3G.)
