Please see the updated NetworkManager PPTP Plugin for Ubuntu page. Thanks!
Some time after blogging about getting NetworkManager's PPTP plugin checked out of CVS, I have some news to report.
Tony Mee is a legend. The author of the plugin has spent a lot of time with me, by e-mail, Jabber and Skype, accepting bugfixes, working on solutions, explaining things slowly for my non-programmer-brain. Most of the work done has been by him. I can't thank him enough here.
A few points to note first:
- This plugin is in the middle of being converted to handle things that aren't just PPTP, and as such it presents a few more options than it might need to. Ignore screens about GPRS and Bluetooth; hopefully a subsequent version will see me disable them.
- It is the CVS HEAD version, with the new pluggable-auth-dialog removed, as it just didn't want to build right, and isn't yet ready to replace the old auth-dialog.
- Default PPP options might not suit - you will probably have to tick "Refuse EAP" on Authentication and "Require MPPE encryption/Require 128 bit MPPE encryption" on Compression & Encryption to connect to a Windows 2003 VPN server.
- There are a variety of bugs with the current version of NM that could bite you. The VPN plugins can't set the MTU, you can't edit a VPN connection immediately after making it, irrelevant tabs aren't hidden - most of these will require the new 0.7 series to be released, which probably won't happen before Edgy.
- You will have to restart DBUS, or log out and log back in again, after installing this plugin, before you can connect.
As usual, everything I know about autotools and CVS I leant from Perry. Thanks!
Now, for the fun part. I have packaged the NetworkManager PPTP plugin for Ubuntu 6.06. Download it here. I will have it up in an apt repository in the next couple of days. Please raise bugs in the program at the GNOME bugzilla, please leave comments on the package or general messages of "Hello!" in the comments below.
The next step is to find out how to disable all the irrelevant parts in the package, and start considering my potential future as an Ubuntu MOTU.

Thanks for the build Craig.
A note for users:
Don't forget to restart dbus after you install the .deb package.
sudo /etc/init.d/dbus restart
[...] My NetworkManager PPTP plugin package for Ubuntu is sitting in the REVU queue. If all goes well it will be approved and end up in Universe for Edgy. [...]
Hi,
I installed your package on Kubuntu using knetworkmanager. I now have the entries to configure VPNs but where do I actually connect to a new VPN? In "VPN Connections", I have ony "Disconnect" which is grayed out and "Configure".
I have tried running nm-applet instead of knetworkmanager and I have the same entries.
Thanks for any help,
JP
Have you restarted d-bus? /etc/init.d/dbus force-reload (or restarting the PC) should fix that, at least for NM-Applet.
Otherwise, you need to add one before you can connect to it... you do this under Configure?
(New packages in REVU do the reload for you)
Hi,
I have install this plugin and configured VPN using the configure option on network manager VPN. However, the VPN name configured is greyed out togethe with the disconnect option.
What could be the cause?
Thanks.
Ray
If it can't be fixed by reloading DBUS it's not worth fixing 🙂
Hi,
It seems that the VPN plugins does not work when I connect to internet using dialup/PPP. It work perfectly if the PC connected via the LAN port.
I think this is a bug.
Thanks.
Ray
Hi,
Thanks for the plugin, works great here.
I'm having issues with DNS-over-the-tunnel. I need the VPN's DNS server to get auto-added to my resolv.conf.
Syslog says:
NetworkManager: ^IDHCP returned name servers but system has disabled dynamic modification!
My system uses resolvconf - is that the problem? It would be great if your plugin checked for resolvconf and used that when it's present.
Thanks!
Hi! Great work Craig! Are you aware that the latest .deb file available on /~crb/nm is dependant on libdbus-1-2 which is not available on edgy? (libdbus-1-3 is available, though) I had to install the dapper version in order to get this to install...
After configuring the VPN, I try and establish it and I am asked to authenticate, which I do, and immediately (almost too quickly...) it fails with "Could not start the VPN due to login failure. Bad username or password".
I've tried setting the debug option, and looking into every log file I can find, but none of them tell me anything useful...
Any ideas?
Thanks,
Eddie
[...] Thanks to the efforts of the tireless ajmitch (does he ever sleep?), not only is my network-manager-pptp package mostly finished, it's also going to be available in the universe repository for Ubuntu Edgy. [...]
Eddie: see http://craig.dubculture.co.nz/blog/networkmanager-pptp-plugin-for-ubuntu/ for the updated builds.
Gabe: PPP options tab, "Use Peer DNS". Next time please leave an email address so I can contact you!
Much like Eddie, I'm having the same problem about not being able to authenticate, even after installing your latest builds. Looking at /var/log/syslog, this looks like the offending problem:
Oct 3 00:03:22 kernel-mustard NetworkManager: ^IVPN Activation (VPN) Stage 3 of 4 (Connect) reply received.
Oct 3 00:03:22 kernel-mustard NetworkManager: ^IVPN Activation (VPN) Stage 4 of 4 (IP Config Get) timeout scheduled...
Oct 3 00:03:22 kernel-mustard NetworkManager: ^IVPN Activation (VPN) Stage 3 of 4 (Connect) complete, waiting for IP configuration...
/usr/lib/pppd/2.4.4/nm-pppd-plugin.so: cannot open shared object file: No such file or directory
Oct 3 00:03:22 kernel-mustard pppd[8169]: Couldn't load plugin nm-pppd-plugin.so
Oct 3 00:03:22 kernel-mustard NetworkManager: ^I nm_vpn_service_process_signal (): VPN failed for service 'org.freedesktop.NetworkManager.ppp_starter
', signal 'LoginFailed', with message 'Bad Username or Password'.
Oct 3 00:03:22 kernel-mustard NetworkManager: ^IVPN service 'org.freedesktop.NetworkManager.ppp_starter' signaled state change 3 -> 6.
Oct 3 00:03:22 kernel-mustard NetworkManager: ^I nm_vpn_service_stop_connection (): (VPN Service org.freedesktop.NetworkManager.ppp_starter): could n
ot stop connection 'VPN' because service was 6.
So it looks like /usr/lib/pppd/2.4.4/nm-pppd-plugin.so is the problem. On my system, nm-pppd-plugin.so is in /usr/lib/2.4.4b1 and symlinking isn't good enough - the logs then show the error:
pppd[8332]: Plugin nm-pppd-plugin.so is for pppd version 2.4.4b1, this is 2.4.4
So basically it looks like pppd needs upgrading - is this packaged anywhere or am I gonna need to build from source?
http://www.wlug.org.nz/~crb/nm/edgy/network-manager-pptp_0.6.3+cvs20060819-0ubuntu2_i386.deb
The package was building for the old version. Building it on dapper in an edgy pbuilder did this. Edgy on Edgy works fine.
Just to confirm that worked fine - cheers 😀
Getting a wierd error, help 🙂

No idea on that one, but lots of stuff to search for on Google. Other assistance welcomed from readers!

I've the same problem as Eddie on Ubuntu Gutsy:
"After configuring the VPN, I try and establish it and I am asked to authenticate, which I do, and immediately (almost too quickly...) it fails with "Could not start the VPN due to login failure. Bad username or password".
I've tried setting the debug option, and looking into every log file I can find, but none of them tell me anything useful...
Any ideas?"

Same issue as Eddie - ubuntu feisty but not from the outset. I had to fumble around with this to get this messed up. Eddie's message goes away if you uncheck require mpcc (I noticed /var/syslog says "unrecognized option 'require-mppc'.......NetworkManager: ^I nm_vpn_service_process_signal (): VPN failed for service 'org.freedesktop.NetworkManager.ppp_starter', signal 'LoginFailed', with message 'Bad Username or Password'. ) "
Is obvious bum-steer. Meh, bloody microsoft, it might be easier to reconfigure the network admin to install cisco than get this working.
