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'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>] code....
I'm trying to connect to [URL] but it will not work no matter what settings. I have ticked MPPE, configured gateway, username, MSCHAP and MSCHAPv2 are ticked, using 128-bit encryption. I have tried to forward port 1723 and 1127 in my router, I have also ticked "enable PPTP PassThrough" in the router. I cannot telnet to vpn.itshidden.com. This is on Ubuntu Lucid. These are my logs from an unsuccessful connection attempt:
This questions is a little complex but here goes.at a central HQ I have a windows server 2008 R2 machine running routing and remote access. At my home office i have a class C lan with a Fedora 13 machine. I can get fedora 13 to connect using pptp no problem. I have my router running tomato set to redirect all traffic to teh 10.0.0.0 network to my linux server. My questions is how to I make the fedora 13 machine pass all the traffic from my network with destination 10.0.0.0 over the vpn tunnel? so for instance if i ping anything 10.x.x.x from any machine on my network it will find it and reply?
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
I've got a FC PPTP server up and running but can't connect to it using VPN. I'm using NetworkManager but the connection fails each time. On the server, I'm seeing the following in the /var/log/messages:

Ive checked that the name,passwords all match, which they do. Has anybody seen this before ?
I'm trying to get a pptp server up and running. The server starts just fine, but encounters errors when a client tries to connect.
Code:

I assume the failed read line is the culprit. I am currently running on a test machine. There is no firewall. I read on this error points to a firewall misconfiguration, but there isn't one.
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 started a newly started a VPN-service with some friends and are offering both OpenVPN and PPTP-vpn.The OpenVPN works perfectly, but we have some problem with the PPTP.It is possible to connect to the VPN, but once connected you can't get any type of access to the outside world ( the interner ).I've googled (Ok, not I, but the tech-guy has) and havn't found any solution so therefor we try here.We are running Debian 5.0 on a XEN VPS.On the machines we've tested OpenVPN works like a charm.
I have updated the system this morning and the vpn stopped working!It gives me an error: invalid secrets.I use network manager to connect to a pptp vpn connection, I use fedora 12.Does anyone know the problem?
I have servers in remote locations where I have no control over the network routers or firewalls. I need to have a VPN connection to my servers.Is there a way to create a PPTP VPN connection automatically? I don't want to initiate it, I just want it to phone home, and keep phoning home if the connection is dropped.
I successfully installed openvpn and networkmanager openvpn plugin. Then I successfully added a PPTP vpn connection by networkmanager vpn tab which name is "vpn1". But now I don't know how to connect to this PPTP vpn connection. I tried bellow command but no luck. openvpn --config vpn1.config
eth0: 62.2.2.x (public on the internet) GW: 62.2.2.1 (cisco router)
i want to configure my ppptp server to allow users access internet with their own public ips of class 62.2.3.0 62.2.4.0 62.2.5.0
every time i configure my server all users can get thier IPs but they only go out with my server IP same as NAT not routing.
can you show me the proper configuration to make my users connect with public IP and have internet access. use specific DNS ( i did this but some users can not brows by DNS)
is there any way to specify an expired date for each pptp user.
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

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 need to configure Point to point tunnel protocol (PPTP) vpn in centos.
In Windows XP:
We can able to configure PPTP Vpn like this.
" 1. Open the Windows Control Panel.
2. Open the Network Connections item in Control Panel. A list of existing dial-up and LAN connections will appear.
3. Choose the 'Create a new connection' item from the left-hand side of the window. The Windows XP New Connection Wizard will appear on the screen.
4. First click Next to begin the wizard, then choose the 'Connect to the network at my workplace' item from the list and click Next.
5. On the Network Connection page of the wizard, choose the 'Virtual Private Network connection' option and click Next.
6. Enter a name for the new VPN connection in the 'Company Name' field and click Next. The name chosen need not match the name of an actual business.
7. Choose an option on the 'Public Network' screen and click Next. The default option, 'Automatically dial this initial connection' can be used if the VPN connection will always be initiated when the computer is not already connected to the Internet. Otherwise, choose the 'Do not dial the initial connection' option. This option requires that the public Internet connection be established first, before this new VPN connection will be initiated.
8. Enter the name or IP address of the VPN remote access server to connect to, and click Next. Company network administrators will provide this information.
9. Choose an option on the "Connection Availability" screen and click Next. The default option, 'My Use Only,' ensures that Windows will make this new connection available only to the currently logged on user. Otherwise, choose the 'Anyone's use' option.
10. Click Finish to complete the wizard. The new VPN connection information has been saved."
But in Centos how we can able to configure PPTP VPN for this we need to install any package. I got all the vpn access credentials from my office to work from home, but i cant able to join in my office network. because of this prob.
I'm unable to connect to a windows vpn connection using pptp this was working yesterday but for some strange reason it stopped working. My other vpn tunnels to cisco and so on are working great. I have the following log:

Nov 26 17:05:15 falx NetworkManager[1319]: <info> VPN service 'pptp' disappeared I have the latest updates, so that means that selinux was updated today. My selinux policy was enforcing but I changed it to disable and allready rebooted. Iḿ using Fedora 14 (I already regret for making the upgrade from 13, also have a problem with display drivers or something, but thats another story) does anyone encounter a problem like mine with pptp? can you share the solution if there is one?
Alexandre. Update: At the moment after connecting by Ethernet cable to my home network the connection wold be established but no address would work to the remote network, I've disconnected the cable and resumed using my wifi connection and the VPN connection is working again!! I don't have a clue about what just happened.. since itś working I need to get some work done and will provide more info on this matter if I found something new.
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.
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,&
Trying to connect to my office as a PPTP client, I have setup my PPTP connection in Ubuntu 10.04, and the connection is active, as I can see from the top bar, and the output of ifconfig:

I just installed ubuntu 9.10 but there isn`t pptp VPN on Network manager. How can I install its packages?? I dont have any internet access on my linux because the only way to connecting to the internet is pptp VPN for me.
I setup a PPTP VPN connection in ubuntu 9.10 (x86_64) using NetworkManager. After enabling the VPN connection, I can browse web pages (it's perfect) but after a while the vpn connection is terminated! The following is my syslog after connecting and terminating:

I got this working om my laptop but on my desktop this keeps going wrong, its an upgraded system to 10.04. Made a standard pptp connection using network-manager (and the connection is 100% fine, working on laptop and on windoooz machine) This is syslog any ideas, i reinstalled network-manager-pptp and pptp-gnome, but no go no go..
I am trying to connect my pptp client Linux to a pptp Linux server using modem but no success. I can only tweak ppp linux side Observing the following log I found it�s due to MPPE Support configuration mismatch in pppd, pppd (linux client) is refusing to accept MPPE encryption.
