Ubuntu Networking :: Unable To Connect To My ISP Via VPN / PPTP - Enable It?

Sep 10, 2010

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...

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?

Networking :: PPTP Client Fails To Connect To Microsoft ISA PPTP Server?

Sep 17, 2009

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>]

Ubuntu Networking :: Unable To Connect To Port / Enable This?

Mar 22, 2011

I have setup an OpenVPN server on my server box, it had been working perfectly until today. It operates on port 1194 which I am now unable to connect to (tried telnet). I have checked all the firewall rules and they still allow the port and I have also checked to ensure that OpenVPN is still listening to the port, which it's not but I have tried restarting the service and the box which dosent make any difference. The only thing that has changed is that yesterday I installed Openfire, could this have broken something?

General :: Unable To Connect To PPTP VPN With Ubuntu 10.04?

Aug 15, 2010

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.

Ubuntu Networking :: Unable To Connect To Using Wired Internet Connection / Enable This?

Jan 11, 2010

I recently installed Ubuntu 9.10 on my Dell Inspiron 1545 64-bit laptop. Before that I used Windows7. In Windows, the internet connection worked perfectly well. But after installing Ubuntu, I am unable to connect to the internet. The network-manager applet finally says that "You are disconnected". When I do the "ifconfig", I got no IP address.

So, I installed Ubuntu 9.04 in the same system. But the problem persists.

I gone through many posts in this forum but nothing was useful.

Ubuntu Networking :: Unable To Connect To Specific OpenSSH Daemon / Enable This?

May 19, 2011

I have this very weird problem: I'm not able to SSH to 1 specific server on the web. I can access everything, but not that specific server.

When I try to SSH, I get this code...

When I reboot to Windows, I can SSH using Cygwin. I'm using Ubuntu 10.04 Lucid and OpenSSH client 1:5.3p1-3ubuntu6.
I tried sniffing the network with Wireshark, but I cannot understand why the TCP connection cannot be set up. I'm sure it's an Ubuntu problem as I'm able to connect to that server on the same machine, but different OS.

Ubuntu Networking :: Can't Connect To A Pptp Vpn?

Jan 18, 2011

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.

Fedora Networking :: PPTP Server Set Up But Can't Connect?

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:

Networking :: Clients Can't Connect To PPTP Server

Dec 30, 2010

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:

CTRL: I wrote 32 bytes to the client.
Dec 29 23:27:48 frankenstein pptpd[9402]: CTRL: Sent packet to client
Dec 29 23:27:48 frankenstein pptpd[9403]: CTRL (PPPD Launcher): program binary = /usr/sbin/pppd

[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.

Networking :: Make PPTP Routing / Specify An Expired Date For Each Pptp User?

Mar 13, 2010

i have a VPN server PPTPD on Centos 5.3

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.
