Ubuntu Networking :: VPN PPTP Connects But Fails If Remote Session Established On Server
May 10, 2010
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
Image of current settings in network manager:
Syslog:
Code:
May 11 12:08:04 oliver-desktop NetworkManager: <info> Starting VPN service 'org.freedesktop.NetworkManager.pptp'...
May 11 12:08:04 oliver-desktop NetworkManager: <info> VPN service 'org.freedesktop.NetworkManager.pptp' started

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....

1st, i managed to make a VPN connection to my server and after a reboot i get this:I've tried everything that google gives me with "ubuntu vpn service failed to start pptp" search terms.2nd, I've got a DSL connection (PPPoE) to the internet. When i connect it, eth0 looses it's ipv4 ip (I've disabled ipv6). How can I keep it?

I've configured an openvpn server on a wrt54g using dd-wrt firmware. I can connect from the command line...at least it appears to connect, but I am unable to access any resources. Trying to use networkmanager's openvpn client fails every time. Everything I find googling relates to Ubuntu, so just for kicks I booted into my Ubuntu partition for the first time in months....and the wireless lan disappeared when I restarted network manager, which is why I don't use Ubuntu in the first place, so much for the "easier distros". I'm assuming there are people successfully connecting to openvpn servers from Slack. I could definitely use a pointer.

I have a Compaq Presario CQ42-195TX laptop with Ubuntu 10.04 (64-bit) installed on it and fully updated. It has a Realtek RTL8191SE wireless chipset which I am having trouble with - its wired connection is working perfectly.After starting up, I am able to see and connect to wireless networks. Once connected, the wireless functions correctly for a very brief period (under 10 seconds) in which I am able to access the Internet and so forth. The connection then stops working - although it doesn't get disconnected. When I say it "stops working", I mean I can no longer access the Internet and trying to ping the router gives me a "Destination Host Unreachable" error. If I disconnect from the network I cannot reconnect, nor can I connect to any other network.- though I can still see the list of available networks.
I thought that maybe this was a 64-bit issue, but I tried the Ubuntu 10.04 32-bit live CD and experienced the same problem.Please note that while this thread is about the RTL8191SE chipset, the RTL819xSE chipsets all use the same driver.Below are the results of various commands while connected to the network but after the connection has stopped functioning correctly:lspci -nn | grep "Realtek"
Code:
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8171] (rev 10)
03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast

I am using relakks.com VPN Service and set it up with gnome's default nm-manager interface. Everything is just perfect when I'm browsing the web. I can do it for hours and nothing happens. On the other hand, when I open up a torrent client - after 15 seconds to 2 minutes - I get a nice kick off the VPN.
It goes like this:
Code:
Sep 20 08:25:11 NPC pptp[3496]: nm-pptp-service-3490 warn[decaps_gre:pptp_gre.c:426]: discarding bogus packet 94236 (expecting 93663)

I have configured a VPN connection to a remote router which connects ok. I can ping the remote router IP, but cannot ping any other IP on their network.I have put this down to needing a route added. I can manually type # route add -net 192.168.1.0 netmask 255.255. 255.0 dev ppp0 and all works like I want it to, but I really need this to be automatic everytime the connection starts.I have tried following URL... but cant get it to work. The file is called /etc/ppp/ip-up.d/routing and has execution priviledges (755) so ive hit a dead end.

How do I obtain information about the running x-server from a remote shell session? I want to know things like resolution, color depth, etc. My xorg.conf is basically empty. The only thing I can think of doing is to read the Xorg.0.log file which seems inefficient.
I thought that 'xrandr' displayed some text output but that behavior has changed (?). It seems to require an X display. Is there another way? Something I could incorporate into a shell script? (This is Fedora but that shouldn't really matter)

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.

I have a Slicehost VPS and I'm trying to set up PPTPD on it. I only have one IP address (the public IP of the box). All the PPTPD howto's I've seen rely on assigning remote clients IPs from the local subnet (e.g. the PPTD server's local IP is 192.168.0.20, and remote IPs are taken from a pool of 192.168.0.30-40).
However I don't think I can do that as I only have the one IP address on Slicehost's network - that public IP (and all other IPs in the segment are public). So what I really want to do is to be able to create a private LAN segment or virtual network adapter and have VPN clients assigned addresses in that segment, then routed out onto the Internet effectively using the PPTPD box as a router. I am using Ubuntu Hardy (LTS).

I have to do some work on an Ubuntu 7.10 based workstation that is within a clients network (meaning I have limited ability to change network settings and I would rather not have to ask if possible). I am using OSX to connect. The client has given the the following access:
1. PPTP VPN access to their network
2. SSH access through the VPN to the Ubuntu workstation
3. Generally unlimited access to the workstation OS
4. Client is on a different continent so I cannot physically access the machine
I need to see a GUI desktop however, so I need to run a virtual desktop. Q. Is it possible to run a virtual desktop under these constraints, if so could you point me to help / tutorials?

Running Ubuntu 11.04 Server 32bit fresh install
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:

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.

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:

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?

Updated occurred yesterday and installed new ppp on my F12 box. my previously working, stored PPTP profiles under network manager failed to connect claming some thing about security credentials wrong.) downgraded (yum downgrade ppp) , rebooted and its working again. Im not sure where the real problem is, can "the gods above" or below either forward this to the apporpriate bug tracker (packager, testing, redhat, who owns ppp? network manager?) so this is fixed or downgraded in the next F12 update cycle?

I have one pc on which I have installed slackware and samba (fixed IP, mask 255.255.255.0) I have another PC (also XP) which also has fixed IP running XP, and I can connect that to the slackware server easily My third PC connects to the internet and gets its IP address from the Cisco router(?) that provides the IP and mask on boot up.
I tried changing the IP and Mask on the slackware server to match the internet PC (which uses a mask 255.255.254.0) but the PC mask and IP changed on the internet PC I want the PC that connects to the internet to also be able to connect to the slackware server, but I see no need for the slackware server to also connect to the internet - I will mainly use it as a file server When I worked for another company I think the IT department talked about having 2 network cards in the PC that connects to the internet

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 set up a tower with 11.04 desktop as a minecraft server and I would like to be able to access it from work for whatever reason.I set up RPD and checked all the necessary check boxes, opened ports (to the best of my knowledge), installed tightvnc on the remote computer and gave it a go. SUCCESS... almost. It connected and brought up the desktop as desired, however the image seems "frozen". By "frozen" I mean that I am still able to click around and do things on the server, but I just can't see what I'm doing because the remote client isn't "refreshing". It just looks like nothings happening. Example: I move the cursor to the menu bar and click on Applications. It looks like nothing happens however if I walk over to my server, the Applications menu has been clicked and has extended.
If I log out of the remote client and then reconnect I will see this on the remote box, but nothing after that.I hope this is making sense. Does anyone have any idea what could be causing this? I have tried this on two separate computers, one that is on the same network as the server (with both local IP and external IP) and the other is at work. Both do the same thing.
