Ubuntu Networking :: Unable To Connect To A Pptp VPN With Network Manager?
Mar 24, 2010
I followed (or at least tried to follow) tutorials on doing this. I installed network-manager-pptp and tried to configure network manager to connect to a VPN. In the settings when I select MPPE with 128-bit encryption, after I've selected it and applied it, I check the settings and it's invariably unchecked. I tried using KVpnc after getting frustrated with network manager, and I can't seem to get that working either. I've been trying to search for info on this, and I can't seem to find anything on why I can't select MPPE with 128-bit encryption. That seems like it might be why I'm unable to connect to the VPN?

I have a 5720 Mini PCIE broadband modem card and though it works, it won't connect automatically in a Ubuntu system. Network Manager says it is enabled when I right click on the icon, but when I do a left click it says it is disabled. I have to right click and disable and then enable before my Verizon connection will work.

I currently managed it to get a pptp-connect to my home network. now I have another little problem. NetworkManager always routes the whole network traffic over my home network if i am connected to the home network.If i set the "Use this connection only for resources on its network" I have do manually say:
Code:
route add -net 192.168.1.0 netmask 255.255.255.0 dev ppp0
After that only the correct traffic runs over the vpn. Now my question is it possible to setup the route via the networkmanager gui?

I'm trying to establish a connection to my ISP which uses PPTP protocol and a VPN server. The deivce I got from my ISP is a modem, not a router. The problem is my computer is unable to communicate with the ISP VPN server.
P.S Here are the instructions for Windows XP which work: http://portal.bnet.hr/ZG/windows-xp.htm
Here's what I have done so far code...

I'm using ubuntu karmic and I'm not able to connect to the internet with my reliance netconnect data card using network manager. Other distros like fedora, opensuse n sabayon connected easily with nm. Ubuntu detects the data card flawlessly but just doesnt connect.This problem has been persistent even in previous ubuntu versions, n I used to use wvdial. But downloading wvdial on some other comp with every dependency is really cumbersome.

I've searched the forums (250 thread limit) for a fix on this, but all the questions seem unanswered or unrelated. My situation is this: I'm running Ubuntu x64 10.10 'Maverick'. I have a cablemodem connection for my Internet access. I have home network running on DD-WRT with the dreadful Linksys WRT54G series router.
My DD-WRT router is 192.168.1.1, subnet 255.255.255.0.
My Linux box is 192.168.1.61, subnet 255.255.255.0.
I have a VyprVPN connection set up successfully on Linux. Mostly everything works great, speed's fine, latency is what I expect it to be. Except... I also run an SSH server to remotely admin the box at port 22, an Apache server running over SSL at port 7001, and a Transmission web client at port 7002 (only secured by basic HTTP realms auth). All of these things worked before I got the VPN working, I'm of course using NAT at the DD-WRT router.
The endresult I am looking for, is to have the security and protection of the VPN (even if it's only perceived) for everything I do on this machine -- EXCEPT on Apache, the Transmission web panel, and the SSH server, which I want to access from the outside world. I have no firewalls running or configured, not even iptables, not even the SPI firewall on DD-WRT. All connections to the aforementioned services from the outside world timeout coming in to the Linux box. They all work from inside my home network (182.168.1.0/24). In case it's needed, he's my routing:

I've FC10 installed. After updating a few days back, I'm unable to use Network Manager to connect to the net through my USB Modem. All the threads I've read say to do
Code: yum update NetworkManager but how can I do it without net connection? Can anyone post the exact link of the Network Manager's latest and BUG-FREE rpm so that I can directly run it?

I'm trying to connect to a Microsoft ISA PPTP server from my Linux box. The box I'm connecting from is itself a router. I have no problem connecting a Windows XP machine to the VPN via this machine. This is fine, but I would rather connect via the Linux machine, giving me far more advanced routing options (i.e. no to send every packet from the XP box completely unnecessarily via the PPTP tunnel). The Linux router is running Debian Lenny.
I've checked iptables. There were initially some issues. I've fixed those.
Invoking pppd from the console, I can see that authentication succeeds, but then some negotiation goes wrong and the server terminates the connection. Here's the output from pppd, with the more sensitive stuff removed:
Code:
<hostname>:~# pppd call <peer> nodetach debug
using channel 19
Using interface ppp0
Connect: ppp0 <--> /dev/pts/2
sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xe3e45f75> <pcomp> <accomp>]

I'm trying to connect to my corporate VPN using a laptop running Ubuntu 10.04. It's a company laptop but as I have chosen to run Linux rather than "a proper" OS, I'm mostly on-my-own as far as getting these things working. Normally that's OK because I am almost always successful - except this problem has had me stumped for several weeks now.
The problem is that I am unable to access the VPN from my home network. I am using the Gnome Network Manager interface to configure the PPTP connection but no matter what combination of options, domainusername formats, encryption options or authentication methods I select, I get the exact same behaviour, which is essentially a 10-second wait, and then a failure message. I checked /var/log/daemon.log:
Aug 15 22:27:46 pc770-ubu NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...
Aug 15 22:27:46 pc770-ubu NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started
[Code]...
the laptop is connecting to the Internet via a WiFi access point (bridge mode), then an ADSL router. PPTP pass-through is enabled on the ADSL router and Access Point. if I connect the laptop to the ADSL with an ethernet cable (to eliminate the WiFi), there is no improvement. another laptop (running Mac OSX) is able to connect to the VPN, via WiFi or cable. another client, Windows7, is able to connect to the VPN via cable. an iPhone is able to connect to the VPN via WiFi. this laptop is able to connect to the VPN from inside the corporate firewall.
So I've got three other devices that are able to connect to the target PPTP VPN, and a laptop that can't, except when I move the laptop inside the target network, it can connect. I've tried methodically selecting various VPN options with no change in result. I've also read several Ubuntu Forum posts suggesting turning off EAP and that doesn't help either. I'm now at a loss how to fix this, and what will happen next is I'll be told by Management "we told you so", drop Linux and switch to a "proper" OS like Windows instead, which I really don't want to do.

I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
Code:
#!/bin/sh
case "$1" in

I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.

I recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.

since installing opensuse 11.2 KDE, is that I can connect to the local resources when I'm not connected via the pptp vpn to the Internet but as soon as I establish an Internet connection, I cannot. Under Windows and other distros I've tried, this has never been an issue, usually I can connect to either local or Internet resources, interchangeably. In a nutshell, I don't know how to troubleshoot this.

I have installed and setup 3G which works perfectly fine. I use sakis3g scripts for connecting to 3G network. My VPN profile created with network manager (client/NetworkManager GUI) works well.
#cnetworkmanager --activate-connection=user,'XXXXX_vpn_singapore',wlan0,&
Now when I do the same with using using ppp0 (which is after connecting to VPN) I get the following error messages. #cnetworkmanager --activate-connection=user,'XXXXX_vpn_singapore',ppp0,&

I'm running Ubuntu Karmic Server with Xfce desktop, the problem is the network manager, it says it is disconnected, even though I am connected to my network and getting an internet connection. It wouldn't normally bother me, but I'm trying to setup a VPN using the network-manager-openvpn plugin. I put in the required details for the VPN connection, but as soon as I tick the "apply to all users" box, the information is lost. The information will remain if I don't tick that box, but it will not connect. when I try to select the VPN connection I just setup, nothing happens.
I've tried the exact same configuration on another desktop, running Ubuntu Karmic with Gnome desktop, the network manager works fine, my ethernet connection is showing as connected, and I can connect to the VPN no problem, the problem lies with the network manager in Xfce. Is there anyway I can get it to show as connected? it wont allow me to connect to the VPN otherwise, it's silly, because that adapter has a full working network connection.

I'm trying to use wicd instead of network manager because I want a "no fuss" way to use wireless on wmii. However, wicd will not find any networks unless network-manager has been run and has connected to a network since startup. If it hasn't connected to a wireless network, the wicd will find no networks, and iwlist won't provide a list of networks either.
This seems to mean that network-manager is doing something to the interface when it connects that needs to be done to make it usable, but I'm not sure what it is or how exactly to find out. I do know that the interface (eth2) will not appear in ifconfig if network manager hasn't connected, which I assume means that it hasn't been brought up. ifconfig eth2 up makes it show up, but I still can't connect with wicd. What can I do?
I'm running Ubuntu 10.04, generic 2.6.32-22 kernel, MacBook 5,5 using the Broadcom STA driver. (more details below)
Code:
*-network
description: Wireless interface
product: BCM4322 802.11a/b/g/n Wireless LAN Controller
vendor: Broadcom Corporation

bus info: pci@0000:03:00.0

i was fed up after i can't connect to wifi using ubuntu. the problem happened after my router is being replaced to a new one because the old one got struck by lightning. good thing i dual-boot my laptop so i can access the internet using Windows 7 now.
i use the default network manager to connect to wifi before, but it all seem to be failed after the replacement of router. i also used Wicd but it failed to connect either. it says in the notification "disconnected: bad password" but the password was right. my wifi used WEP password with open authentication.
i even remove the WEP password and try to connect, but it failed. all i can do is to boot in windows 7 and surf internet there. what could cause this problem? is it the router, the telephone line? i can set the router settings if i want, but i don't know what causes the problem.

I have a problem with network manager. I use Ubuntu 10.04 on a Dell Latitude D530. I used to have the same problem with Ubuntu 9.10 before I upgraded. I typically connect to two wireless networks: HOME and WORK. Both networks are set to automatic connection mode. I am at work, I connect to the network WORK. At the end of the day, I just close the lid and go home. At home, I open the lid and have the following problem: network manager still displays the network WORK whereas it is clearly out-of-range and it automatically tries to connect to it. It does so until network manager asks if the password is correct.
If I want to connect to HOME, I have to tell network manager to do so. Then, I receive a notification that I am disconnected to WORK. Next morning, I go to work, and I have the same problem, network manager tries to automatically connect to HOME. What I would expect from network manager: when I am at home, NM automatically connects to HOME and does not display WORK, when I am at work, NM automatically connects to WORK and does not display HOME.

I have ticked the box Connect Automatically in the OpenVPN setup I configured in the gnome network manager but it doesn't connect on startup. It connects perfectly ok if I manually select the VPN but i'd like it work immediately on launch.
I have autologin on Ubuntu but since there is no VPN password to decrypt I don't see why it should be a problem.

I am having trouble connecting back to my vpn at work while I'm at home. Mainly need to get our local svn repos for at home development. I successfully connected to the vpn following this [URL]..I am running Lucid Lynx 64bit and I followed the 9.10 section of the tutorial on setting up PPTP connection.
It worked fine. Then I walked away from my computer and it was disconnected when I came back 2 hours later. I was unable to connect back to it. I used my laptop which is running windows 7 and it connected just fine. So, now I am unable to connect to it and have no idea why. I viewed my system log and don't know what to do with the information. Could someone help me out on this.

I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."
