Pptp Vpn? - Page 3 - maemo.org

Hi all,

I am trying to get the PPTP client working using HotspotVPN's service. I followed fanoush's instructions on flashing the kernel and loading the required modules in sequence.

Code:

Nokia-N800-50-2:/etc/ppp/peers# lsmod        
Module                  Size  Used by
ppp_mppe 6660 0 - Live 0xbf06b000
ecb 2784 0 - Live 0xbf069000
pcbc 3776 0 - Live 0xbf067000
cbc 3744 0 - Live 0xbf065000
blkcipher 4772 3 ecb,pcbc,cbc, Live 0xbf062000
cryptomgr 2368 0 - Live 0xbf060000
sha1 2400 0 - Live 0xbf05e000
arc4 1760 0 - Live 0xbf05c000
crypto_algapi 10176 6 ecb,pcbc,cbc,cryptomgr,sha1,arc4, Live 0xbf058000
g_file_storage 27560 0 - Live 0xbf050000
cx3110x 56200 0 - Live 0xbf041000
umac 258788 1 cx3110x, Live 0xbf000000 (P)

Now when I start pppd with 'pppd call HotspotVPN' (HotspotVPN being the remotename configured in /etc/ppp/peers/HotspotVPN) I get the following:

Code:

pppd options in effect:
debug           # (from /etc/ppp/peers/HotspotVPN)

noipx           # (from /etc/ppp/options)

and this:

Code:

Nokia-N800-50-2:/etc/ppp/peers# ps -ef | grep pp
  959 user      18960 SW< /usr/bin/maemo-launcher --daemon --send-app-died --bo
 1564 root       2296 RW  pppd call HotspotVPN 
 1565 root       1884 SW  sh -c pptp es.hotspotvpn.com --nolaunchpppd --logleve
 1566 root       1772 SW  pptp es.hotspotvpn.com --nolaunchpppd --loglevel 2 
 1569 root       1772 SW  pptp: call manager for 67.159.37.134  --loglevel 2

It seems that it is trying to connect. I also noticed that a ppp0 interface is not created like it is on my Ubuntu. I am not sure what program/scripts creates this interface - excuse my knowledge.

After a lot of fighting I was able to get it working on my Ubuntu using the NetworkManager. I feel l am very close to get it to work on my N800. Has anybody gotten HotspotVPN to work on the N800/N810?

Any help would be appreciated.

Thanks.

solved. the require_mppe option had to be enabled.

Hi all, just bought a new N800, and trying to get PPtp working.

I have installed the pptp client, however I have not flashed the kernel yet or installed the modules.

One thing that I noticed on this site: http://pptpclient.sourceforge.net/ho...ian-dkms.phtml
is that it says the mppe support is included in kernel 2.6.15 & above, does this mean I no longer have to get the latest kernel from the infamous fanoush?

I currently am getting the following error when trying to load the client:

rcvd [CHAP Success id=0x0 "S=CDA9CA38B8C4A9BABD04E67299D45CE64BA55FB2"]
CHAP authentication succeeded
MPPE required, but kernel has no support.

I am fairly fluent in Linux, however I have never flashed a Kernel before so I am trying to avoid it (if that's possible).

I am currently running OS2008 v. 2.2007.51-3
Linux Nokia-N800-51-3 2.6.21-omap1 #2 Fri Dec 7 11:17:13 EET 2007 armv6l unknown

Would really appreciate some help, thanks everyone.

Well, mppe support is in the kernel code, however it is not compiled into the standard Internet Tablet kernels. So yes, you definitely have to install fanoush' kernel (or compile your own, of course). Flashing the kernel is easy. And if you mess it up (don't know how you would apart from pulling the wire or running out of power, though), you can just flash the original kernel from the original firmware download. There are command line options to the flasher for that. This way your root filesystem is not touched.

While you are at flashing, I highly recommend fanoush' boot menu and booting from SD cards. Backing up is much easier and having a rescue system on the internal flash is worth a lot.

Hi,

I am new to my N810 with OS2008 and the latest over-the-air updates installed (there were just one). I need PPTP support and am new to both the N810 and Linux.
I managed to get the "becomeroot" package installed (Eko One repository, http://gronmayer.com/it/dl.php?id=136).
I followed this thread and links to other and I pretty much got:
kernel-2.2007.50-2-custom.tar.gz and modules-2.2007.50-2-custom.tar.gz (Fanoush kernels, fanoush.wz.cz/maemo/ for OS 2008) then also Fanoush kernel_flasher utility.
I extracted the Kernel (tar zxvf kernel-2.2007.50-2-custom.tar.gz) and got a zImage kernel image.
I installed it with the kernel_flasher (all files on the internal memory, not on the SD card). Then rebooted the device (reboot command).

Now my device does not boot (Nokia screen for 60 seconds and turns down, not sign of booting, and that's it) I think I can fix that re-flashing the OS2008. But still I have questions.

What did I miss to get this poor result out of my kernel flashing?
What do I do with the modules provided? I have extracted them, but do I need to replace the existing modules, or just use the required ones to get PPTP working?
Is there a dummy guide, end to end "how do I install PPTP support on N810 with OS2008"?
What about the the pptp-client-1.7.1 also mentioned in this thread, is it required? Makes your life easier because you don't have to define config files to define a PPTP session?
I apology if my question appears simple, I am willing to write this dummy guide if I sort out how to get my device working and share it with the community.

Do anybody have ppp_mppe and crypto modules for latest diablo update ( 43-7)?
I compiled its from source but can't load

May by kernel config is wrong or my hands

The kernel you flashed is too old for latest OS2008. You missed version info listed on my site but still sorry for that, it is too easy to miss it. I am not using pptp myself so I am quite slow in updating that kernel image. I'l try to do it tomorrow (~24 hours from now). I wanted to compile custom kernel for latest OS update for usage with my own device anyway so let's kill two birds with two stones at the same time ;-)

I would actually need the pptp support without MMPE, with no encryption whatsoever, if anyone can build a deb for that, would be great!

I am new to internettablettalk(just got my n810 for christmas). My workplace uses a microsoft IAS to provide vpn to us, so as Fanoush's vpn kernel/modules are outdated I took it upon myself to create my own kernel, and everything seems to be working. I also managed to get pon, poff and ip-up.d to work by editing the scripts a bit.

I am not ready to package any of this, but if there is interest for these modifications I would be more than happy to share them with anyone

I am definatly interested in this, I have been working on this for a few days now with little success. I have an N800 with the latest Diable updates. My main problem has been with the routing and getting the Chap to Auth. I am a total Newb to Linux but have read virtually every relavent post on here over the last few months so have a little knowledge. A GUI frontend for this would be a godsend.
