Ubuntu Networking :: Lucid PPTP VPN Failure Connecting To MS Server
Sep 10, 2010
I'm attempting to get 10.04 to connect to an SBS 2003 pptp vpn server, but for the life of me have been unable to find or implement a working solution. System previously had 8.x and 9.x and had no difficulty connecting to same server, but on a fresh install of 10.04 cannot connect.
tail -f /var/log/syslog shows the following:
Code:
Sep 10 15:19:32 ubuntu NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...
Sep 10 15:19:32 ubuntu NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started
I have been wanting to switch from my routers VPN to my headless linux box VPN. I have everything setup in the PPTP and then forwarded the ports to it. Heres the kicker. My APPLE Iphone connects to the VPN without a problem at all. Views Intranet pages etc.
My Windoz XP is kicking and screaming and one error after another. This is my setup on XP: I entered Ip Entered exact same credentials as used for connecting with my iphone turned off "use gateway on remote network" Changed type to PPTP VPN connecting my xp machine to this PPTP server on linux?
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 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.

I am a newcommer to Centos. I should connect to internet via a pptp vpn connection. I created the connection in "network connections". In other distrows I could connect to created pptp vpn connection simply by clicking on network-manager-applet and selecting the connection, but there is no network-manager-applet in Centos. Is there any way to connect to the vpn connection I created or I should go to do it by manually editing config files?
I am running fedora 14 and have tried to setup VPN access to work. I used the simple networking GUI program. Another engineer at work uses ubuntu and that is how he accesses the VPN. I think that I did everything right but get this generic 'VPN connection failed' message. I am trying to connect to a monowall firewall and have the IP address. Yes, I have an account but am just trying it for the first time. I turned on all of the options available which seemed correct based on the instructions that I had. I have contacted my sys-admin to try to find out what the monowall doesn't like. However, I am wondering if I might need to open an outgoing port on my linksys home router/firewall and, if so, which one?
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 having trouble connecting to our home wireless network in Kubuntu Lucid. I was hoping someone here might be able to help. I can connect with no problem in Ubuntu and Xubuntu; I'm having difficulty in Kubuntu only. It might just be me being unfamiliar with the KDE network management app, I don't know.
1. I click on the network icon in the system tray, and choose "manage connections". I click on the "wireless" tab, and click "add".
2. I enter the name of our network in the SSID field (our router doesn't broadcast its SSID; however, if I click "scan" the neighbors' wireless networks do appear in the list) under the "wireless" tab, then I go the "wireless security" tab, and choose "WPA/WPA2 - personal" and enter the password. I click OK.
3. Now when I right-click on the network icon and choose "create network connection", the new connection for our network that I just made shows up in the list, but it has an icon showing a pen on paper instead of the broadcasting signal icon that appears next to the neighboring networks. It also says my connection is "insecure", even though I chose WPA and put in the password. (Neighbors' networks do say WPA, WEP,etc.)
4. I select my network connection that I created above, and click connect, and nothing happens. No connection is created. how the KDE network app works; I've used mostly XFCE and GNOME in the past, but I've heard good things about Kubuntu Lucid and really would like to take it for a spin. However, this computer has only a wireless connection, so I really need to get it working.
Evolution won't connect to our Exchange Server 2003. I have the Evolution-Exchange plugin installed and the Evolution vsn is 2.28.3. The Ubuntu vsn is 10.04 lucid. In the setup of the mail account I enter the user name in the form domainusername; in the OWA URL I enter the URL in the form - URL... and then I click the authenticate button (can't progress without authenticating). When requested I enter the password. Then comes the error message - could not connect to the server. Make sure the url is correct and try again.
I can connect to OWA using a browser. However I have to negotiate past the browser warning me that the server has a self generated certificate and not from a trusted authority. Maybe this is the problem, I don't know. The fact that I can get to OWA by means of a browser means that the firewall in our router is configured correctly, as is port forwarding to the server.The domain/exchange server is in our office and I have administrator rights.
Tried to install pptp vpn server via webmin, and I tried connecting remotely from my laptop, but it keeps failing on the verify username and password - I get a error 778 it was not possible to verify the identity of the server. Not sure what could be wrong with the config..
I did this walk-through trying both iptables and ufw
I am able to connect to my VPN server using both windows 7 and Ubuntu desktop just fine, and using wireshark verify that all packets are being compressed and sent through the VPN tunnel.
Many sites work but there are several that will not load while using the VPN, one of them is ubuntu forums also sourceforge.
I can ping the servers while connected but the websites just will not load, and time out. The second I disconnect from the VPN they load instantly.
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:
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

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'm trying to use a vpn server which uses pptp. I've set up pptp as per the Debian Howto and it seems to be working, but I'm not actually acessing the net via the server.Not sure what info would be useful but here are route -n and ifconfig.Can anyone suggest what is wrong here, and how to test if the vpn link is actually working?
I'm running an own PPTP Server, but I can't get it to access the internet. All my PCs at home run in the 192.168.0.0/24 net, the PPTP Server has local IP192.168.0.5 and remote IP 192.168.0.80-99. The router to the internet is at 192.168.0.1, and the IP of eth0 on the machine where the pptpd runs is 192.168.0.4. I want to be able to connect to the internet trough that VPN and access my local LAN servers (which works fine so far). I can ping internet and local IPs successfully, but can not access them with a browser, or connect to them in any other way. I have 'accepted' all in/output and forwards.
I am running a Squid proxy on the same machine, and if I do: iptables -t nat -A PREROUTING -j REDIRECT -i ppp0 -s 192.168.0.0/24 -p tcp --dport 80 --to-port 3128 I can access the internet through Squid, but of course Jabber/ICQ etc. Won't work then because it just refers port 80. But I want the PPTP Clients to connect to the internet directly, if I don't use that rule it's not possible to load any pages. But pinging works all the time. DNS is also working fine, but I can't even access webpages via IP directly. How can I allow the PPTP IPs 192.168.0.80-99 to get direct access to the Internet with Iptables?
I am trying to connect to a windows 2000 VPN server at work, with my current settings in DOES connect to the VPN and i can ping the domain server which is 10.1.1.2 but the first issue is i cannot ping the other computers on the network(via hostnames) can't remember the ip address of the other machines . second issue is when the connection is established and i RDP into 10.1.1.2 ok great i am connected to the server but any interaction in the RDP session even moving the mouse on the screen kills the session and the VPN connection fails.
Running Ubuntu 10.04 LTS 64Bit

recently i rent a xen vps intended to setup a PPTPD vpn server for me and my friends. so we can by-pass the great firewall in china and get back on ....., facebook and stuff. i have already setup the server and i can connect to it without any problem. but i still want to do some further configuration the server:
1. i want to limit the bandwidth to 400k/s per connection. 2. i also want to limit the max connection per user a/c
i have some thoughts on the 2nd requirement. in the user configuration file of /etc/ppp/chap-secret, you can specify the range of ip the user can get, does it limit the max connection per user a/c? or they can connect anyway, just every now and then a box pop up says conflict in IP address?
I am having a problem in burning my CDrs. I can't! Whenever I try to burn a CD, it starts up and then gives OPC failure. This is the info from Gnomebake
I have a home server that I have setup to connect to via SSH. All is working well with that. I would like to have the home server access the internet through a VPN. However, if I do this, I am no longer able to connect to the server via SSH, even though I know what its IP address is.
I am having problems connecting to my VNC server. The host machine is running fedora core 15.
In the past I have been able to connect to the machine, but for some I no longer can't.
I have done the following but still am unsure what problem is 1. Verfied the VNC server is running 2. Verified my user "trb" is in the vnc users list 3. I have checked that my port is open (at least i think). i launched a terminal and did "telnet 127.0.0.1 5902" and successfully connected.
My vncservers config file which is located in /etc/sysconfig/vncservers

Here is the log file from my latest connection attempt.
When I try to update my system(10.04 Lucid) it gives me this error message.

I'm trying to connect to an XPpro machine using terminal server, I've been to the microsoft web sight and configured xp as they explain. Which consists of "allow remote desktop connections" and "re configure the fire wall", Done. I've obtained the ip address of the router and the user name and password of the xp machine and still I cannot access it!
I've been experiencing some home web-server slowdown issues lately, and I wanted to see if it's a problem with the server itself. I'm not sure if this might be the problem, but upon checking netstat -tn, I see over 15 instances of the following:

where 192.168.2.9 is the server's local address, the local address port varies, and the foreign address is the server's web address. If anyone knows what might be causing this and/or how to fix i
I have setup an ubuntu gateway server by using four NIC cards.
eth0 :210.212.235.107 is connected to the internet eth1 :192.168.1.222 is connected to the local network eth2 :192.168.2.222 is connected to another network
Here 192.168.1.222 is the gateway for 192.168.1.0 network and 192.168.2.222 is the gateway for 192.168.2.0 network.These network configurations are working fine, but i want to block inter network communication ie from 192.168.1.0 network to 192.168.2.0 network,i want to block the communication for securing the local networks more.I know iptable rule is enough for this purpose .But i cant find the apt rule for this purpose.
i have two subnets with different gateways.i am thinking of connecting them via a linux server which would enable them to communicate.but i dont know how to proceed for getting this done.how should the connection be made and what should be the configuration settings on the linux server.
Had mythbuntu/xbmc running for 4 months with vdpau and all the same hardware. I killed it with an update and thought it'd all be easier To build it the 2nd time -- wrong! Fresh install of mythbuntu lucid off cd, Asus p5g43t-m pro, nvidia gforce 9500 gt
What I tried so far...Different drivers with the hardware app thingee. Multiple times -- Purge nvidia, purge nouveau, blacklist list of other video stuff with extra line after, stop gnome, manual install various drivers - 195.xxxxx or Synaptic install various drivers. Tried updates, adding avenard and daily build repos. Everything in combinations. Outcome remains consistant. Lo res error start, can't load nvidia driver, selected but not in use, xorg.conf needs editing.
I'm getting the same error messages as the common nvidia help posts describe but the solutions aren't working for me.
4 days of this, 3 installs plus a shot at Mint, and no progress. I'm pretty frustrated. I'd consider returning to karmic if I didn't think the updates would pork the nvidia driver all over again.
Last install of 9.10 there was a required edit of vmalloc=256M and a shut off of cx18. That's been fixed in lucid? What else ccould it be?
