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?
View 1 RepliesI'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

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.

i m new to ubuntu i want to create a pppoe client with a service name. i used to create it with pppoeconf but it is not asking me for the service name. i went to /etc/ppp/peers then i typed gedit dsl-provider. i opened the file
[code]...
i put in the bottom servicename="ROG". when i pon dsl-provider it said unrecognized option servicename. i put in the header of the file this line : pty "/usr/sbin/pppoe -I wlan0 -T 80 -m 1452 -S ROG". nothing changed i still cant connect.
What is the best client application for connecting through PPPoE (DSL connection)? Gnome's default network manager isn't very useful. I created a DSL connection but don't know how to use that.

View 1 Replies View RelatedI'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 installed Debian Squeeze on my system two days ago, using a wired connection to internet (which worked fine). After that, I had to install the non-free wireless package in order to scan wireless networks. It now works fine, and I can connect and get to internet. But with wired connection, i connect via eth0 and none of my applications work. And they're not in offline mode.Also, i already went here: URL,,, and I checked if that was my case. I tryed what they say several times in some different ways, but I still can't connect. Even more, if I change something like they say, I get "unmanaged device" and I can't even connect to the internet. And the wired connection works, I'm using it right now on my ubuntu 10.10.
If you want more information, I just tried to ping sites like google.com or ......com using network preferences and it does work, it gets 100% of the packages back around 50ms later, so the internet appears to work. Also, when I connect via wireless, everything works perfectly.

View 7 Replies View Relatedi 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'm using opensuse 11.3 and can't connect to the internet, my eth0 interface (which would be my modem i suppose) is found and when i "activate" it with ifup eth0, it gets stuck waiting for data (says so in ifstatus). If i try with knetworkmanager it is also stuck and doesn't connect to eth0. If i try to make it connect at boot, it doesn't work either.
I think the problem might be that in windows xp my modem has a "limited connection" but i can connect with my pppoe password anyway, but opensuse won't let me connect until it finds eth0 is working correctly which it never will because of how the internet company configures the modems i think. I don't know with which command i could "force" the pppoe connection even without a good connection to the modem, maybe that would work. But on the other hand, with other distros i can connect just fine so i don't know really.
now my system does not connects automatically when fedora start's to eth0 i have to connect it manually by pull down menu in the beginning hostnname was dbe272b22.dslam-172-17-161-245-0532-474.dsl.cantv.net i do not remember if the last part ".cantv.net" was there.... i changed hostname "dbe272b22.dslam-172-17-161-245-0532-474.dsl" maybe ending with ".cantv.net" with system-config-network for hostname "edicta" i modified /etc/hosts by hand twice, now do not remember what i did exacly but here you can see /etc/hosts

View 1 Replies View Related5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?
I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5
eth0 - Public IP - full LAMP services on two or three virtual interfaces
eth1 - Private IP 192.168.0.1
The G4
eth0 - Public IP for ssh
eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).
I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side.

I do randomly (as far as I know) loose my wireless network connection. The only thing to do then is to restart my router and after that it works for a while. I know this is not a hardware issue because I don't have this problem with KDE, only in gnome. I think this problem occurred after I started using 10.04, but then I changed to KDE and forgot about it. But now I'm using gnome again and loosing my network connection over and over drives me mad

I have a problem with network on centos, after i restart the server it works for few hours/couple days, and the network is dropped. - no errors in the log, only that "Network is unreachable" I do 'service network restart' comes back on- directadmin, dns, awbs- everything works good, but only for few hours(never longer then couple days), and then it is dropped again. I searched many forums, and on one them someone wrote that it is because that static IP was used on the same network by other machine. I had a different server running with that ip on my network before, but it was few weeks ago, and there is no other server connected to the network right now (I have one desktop connected with dynamic ip, and it has no problem), and i still have the same problem.
I was suggested to set a cron jobs to restart network every few hours- i thing that is not a solution. Does anyone have any idea what could be a problem? Anyone had similar problems? What could be the reasons for the network to be dropped after few hours? Here is latest 'dmesg' output after losing network:
