Networking :: Connecting PPTP Client On (Ubuntu)
Jun 29, 2011
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.
pppd[24545]: pppd 2.4.5 started by root, uid 0

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 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 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'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 trying to setup IPv6 in a PPTP client configuration on Maverick, but in network manager only IPv4 is available.
On LAN and WLAN IPv6 is working fine but I want to avoid when using a VPN all IPv6 connection are bypassing the VPN which compromises the VPN to a certain extent ..

im centos 5.3 At first, I used pptp-1.7.2-3.rhel5.i386.rpm from [URL]. But it didn't appear any process of install without a warning about the key problem, and I can't use rpm -e to uninstall it, I just uninstall it from xwindow. Then, I download the pptp-1.7.2-3.tar.gz from [URL] After make and make install, it appeared a problem when i do # pptpsetup --create tunnelname --server xxx.xxx.xxx.xxx --username somebody --password sercet。It told me "./pptpsetup: couldn't find MPPE support in kernel."
But im centos 5.3,and uanme -a: Linux localhost.localdomain 2.6.18-128.el5 #1 SMP Wed Jan 21 10:44:23 EST 2009 i686 i686 i386 GNU/Linux The kernal is support MPPE, and I have reinstalled the ppp-2.4.4.2-el5.rf.i386.

trying to create a "local network" by directly connecting an IBM Thinkpad with Debian Linux installed on it to an Alix computer running Voyager Linux. I'm following a "how to" I found to create a music server, hence the requirement. My issue is I can't get a static IP address to be configured on the Debian machine.I've trawled the net and have found the instructions about editing the /etc/network/interfaces and have tried to do this. First I tried to get DHCP working so I could connect the Debian machine to the net and this proved successful. I edited the interfaces file to look as follows:
# The loopback network interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
Then I tried adding a static IP address to the machine. As this is a network purely between two machines I made up the IP addres and used 192.168.0.1 and used a NetMask calculator to give me a NetMask of 255.255.255.254 (I told the calculator there would be 2 machines on the network). I then edited the interfaces file as follows:
# The loopback network interface
auto lo
iface lo inet loopback
[code]....
I re-booted the machine (ifdown eth0 followed by ifup eth0 keeps saying that eth0 hasn't been configured - a problem there that I don't understand), but during boot up time it failed to assign the Static IP address to eth0 and made me go into SU mode. To fix it I simply replaced the interface file with the static IP inputs with the file that had the DHCP entries (I'd made a copy of the DHCP file), and re-started the machine. Everthing came up fine. So the first question is how do I get a static IP address to be assigned to eth0 such that whenever I shut down and restart the machine the static IP address is always loaded?
The second question is around creating the network via the cross over cable. From what I've found via Google, all I should have to do is create a static IP address on the Debian machine and a static IP address on the Voyager machine. Once they're connected by the cross over cable they should see each other. Is that correct, or do I have to do anything else?

I'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 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 am trying to config linux box as router.
I have CentOS 5.5 client and host in VBox. I can't connect them (I am using bridge adapter mode) as I don't have router in between.
I just created DHCPD on host, and followed
[URL]
But that don't seem to work also. Host is 192.168.1.10 and client is 192.168.1.100 but when I ping host from client, it says Destination host unreachable.

I'd document here the way to get to eDesktop through linux (debian, ubuntu) at the University of West Florida (UWF), since they appear to only support Windows through their documentation on the University web site, and the link through Argus (the secure web site) doesn't work in Linux. This is sometimes needed to use the University resources (libraries and computer programs) from remote locations, and otherwise a google search is fruitless. I had to have a guy in the computer science department show me how to do it. This may apply for other Universities with similar setups. It was impossible for me to figure it out on my own, I had to go back to my old 9.04 partition to get the info...
1) Open Terminal Server Client (Applications>Internet>...)
2) Insert as follows:
Code:
Computer: eDesktop.uwf.edu
Protocol: RDP
User Name: YOUR USERNAME
[code]...
3) OPTIONAL BUT RECOMMENDED click Save As and save it as a quick connect so you don't have to refer to this again.
4) Flip through the other tabs and configure as desired, and click Connect!

Before we use CentOS 4 and all work fine. We start x11vnc by ssh like root. And after this connect by client login in X screen. In CentOS 5 this way don't work. For connect we must login by local from keyboard, start x11vnc ssh by logined local user, and after this we may work, but can't change users.

I'm using Nomachine NX client for Windows to remotely connect to my Ubuntu.Every now and then I experience a strange phenomena: the text in the prompt of all open terminal windows becomes black, so it can't be viewed over the black background. Typed commands are also black, but the results are in normal colors. So I can run stuff, but can't see what I'm typing...After I close all open terminal windows and start a new terminal window, everything goes back to normal.

I have a white slate centos 5.5 installation on a virtual box at Media Temple (one of their new VE servers). I am trying to create a development environment where I can have Bind9 serve up one set of zone files to me and other developers on the internal network and another set of zone files to external requests (ie... using the views feature). I would like to be able to develop for sites for which the dns is not yet pointed at my server. The network is created by having the VE server be an OpenVPN server, and connecting my client box to the server (my mac - 10.8.0.6 / my ve server 10.8.0.1).
I have the connections working fine, I have also been able to route all network traffic from my mac through the vpn to the server. For some reason, I cannot get the DNS server on the ve server to serve me an internal view zone file. When my vpn is on, I cannot ping or navigate to any web pages from my mac. I think this is because my ve server is not setup as a dhcp server and the ip tables are not setup to allow all internal requests to use the server to go get web pages.
I cannot view-ping anything else from my mac/client when on the vpn, I can successfully ping any website my ve is authoritative for. This tells me that my ping is obviously going over the vpn, and thus an internal request, but the external zone file is still served up. The following is my named config.
acl "lan_hosts" {
10.8.0.0/24;
127.0.0.1;
};

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.
