Fedora Networking :: Cannot Get A Virtual Private Network - Error Key Pair Generation Failed: "-8037"
Sep 24, 2009
Fedora 11 I have tried just about everything in webmin, the current one I am working with is openswan, and I get this error: ipsec newhostkey --configdir /etc/ipsec.d --output /etc/ipsec.secrets ipsec rsasigkey: key pair generation failed: "-8037"
My boss would like to have our employees connect to our linux server, then access their personal computers to work when they are unable to be in the office. Everyone else in the office uses winblows and they are unwilling to try anything else no matter what the benefit. The most important one is the CAD guy, we need him to work on drawings from school or his latest flings house and I am just running out of steam. how to fix this error or radically change my approach, I will try or do anything.

I have openSUSE 11.2 installed and i need to create a gateway server that allows virtual private network connections. I want to play with my friends some lan games, but we are in different networks, so i want to create this gateway server so we can connect with VPN clients to this server and play freely.

Well to make this straight forward as possible I want a program like The Hotspot Shield In Windows and Mac, Its uses's VPN (Virtual Private Network). To view Hulu (And other stuff). A link: [URL]. Or can I use it wine (I don't really think so, by the way I didn't test it out Because its blocked in my country).

When i try to create a virtual machine using the Windows 7 Enterprise Evaluation iso file, everything goes as planned untill i click on the start button. when i click on it i get two error messages. the first: Failed to open a session for the virtual machine Windows 7. The virtual machine 'Windows 7' has terminated unexpectedly during startup with exit code 1. Kernel driver not installed (rc=-1908). The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. reinstall the kernel module by executing
'/etc/init.d/vboxdrv setup'
as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. i have installed the DKMS package, but when i try to run the command stated in the error message, i get another error message in the terminal:
[code]...
i have to install the driver that is specified (vboxdrv) but i do not know where to find it.

Using a fresh copy of server 10.04 im trying to simulate a failed raid array on a pair of 2tb disks. Here is the procedure i have been following so far:
- Remove the dead disk partitions from each of the raid 1 arrays (substitute the correct md devices and partitions)
- mdadm /dev/md0 -r /dev/sdb2
- mdadm /dev/md1 -r /dev/sdb3
[code]....
I get an error here that sfdisk does not support gpt (guid partition table). I thought sfdisk did support gpt? It says to use parted, but i cant find a command that copies a partition table over from another disk in parted documentation. Any suggestions? I suppose i could make the partitions manually, but im writing a procedure for people who arent that technical and i need it to be simple enough to be run in my absence. manually building the partitions would be too hard for them.

I have been working on this for a while now and am absolutely stumped. Basically, what i am attempting to do is make my ubuntu box into a gateway for my network. I have everything working thru hard wire, but I simply cant get the wireless to work. No matter what I do, I cannot get my wireless card to transmit an essid and allow nodes to connect. I have tried assigning it in the interfaces file (shown below), and I have also tried manually modifying it using the iwconfig command. Here is the topology:
eth1: internet WAN
eth2: ethernet out to LAN
ra0: wireless out to LAN
Here is a copy of my /etc/network/interfaces file:

We have to connect one PC in private network (campus) with other PC (mostly a modem in our case)in public network. Connection should be peer to peer like and we have to use C coding for establishing connection between this two systems. Is it possible if we use port forwarding or is there any other way?

The facts are as follows:
1. I have at work a regular LAN with many PCs, each with a DNS-registered public IP. Therefore I am able to address each of these PCs by their fully-qualified names and, for instance, initiate ssh sessions to any of these computers just by typing "ssh <name_of_machine>" from a terminal.
2. Within the aforementioned LAN I have just created a private network with some clients, which access the LAN through a router (a D-link DIR-825). We have created this private network for many reasons, but most importantly because we need to guarantee that the hosts in this network will remain networked among them even if the LAN goes down for any reason (which unfortunately happens often). But we still need to have access to the hosts in the private network from the LAN.
3. I am able to define port forwarding rules in the router in order to access certain services on the private network's clients. For example. I am able to access (by ssh) hosts "H1" and "H2" on the private network from a client on the LAN by defining rules for forwarding ports "P1" and "P2" on the router's public IP to TCP port 22 on the private IPs of "H1" and "H2", respectively. Then I would access each of these hosts from the LAN by using:
>ssh -p P1 [ip.address.of.router] (for accessing H1) and >ssh -p P2 [ip.address.of.router] (for accessing H2)
4. The problem with the port forwarding approach is that it is not easily scalable. For instance, If I wanted to enable ssh access to each host in the private network, I would have to define a port forwarding rule for each machine, and then REMEMBER all these port rules when initiating a ssh session from the LAN in order to point to the right host. And the problem gets worse when considering more services in addition to ssh.
5. The ideal solution would be to be have a means for addressing each host in the private network individually, in much the same way in which I address the hosts in the LAN (which have DNS-registered names). For instance, in order to access hosts H1 and H2 as in the previous example, i would like to be able to just type
>ssh [name_of_host_H1] (for accessing H1) and >ssh [name_of_host_H2] (for accessing H2)
The bottom line:
I guess I can say that what I need is some kind of combined DNS-ing and routing that allows me to communicate with the hosts in the private network from outside of it in a transparent way.
The question is: what are any possible solutions for accomplishing this? I have searched the web and found stuff about things like VPNs, reverse-proxies and NAT servers, but I really can't understand if any of these could serve to solve my problem (BTW, isn't my router doing some sort of NAT-ing already? could I just add some DNS-ing in some way?)

I run a server that is connected to several other boxes in a private network (192.168.0.0). I have had no problems previously, but upon a reinstall of Debian squeeze I have no connectivity to the private network: a ping of other addresses on that network fail. Ping and connection to outside world is fine. This box is configured similarly to another on this private network which connects successfully. I have quadruple-checked all my basic information. I post my ifconfig below of the malfunctioning device, then the ifconfig for equivalent nic on a box connected succesfully to the private network.
Questions:
1.Could it be a cable problem? (I don't see how since the cables have not been changed I do not believe since my reinstallation).
2. What about the difference in the last lines of eth1 below and eth2 of the successful box. Is it significant that the bad eth1 reads Memory:fc3a0000-fc3c0000

give a reference to the definition of 'isolated network' as used in the Virtual Machine Manager? I have virtual machines that I do not want to have access to the host, I thought 'isolated network' did this but the VM's can ping the host. If (probably) I am wrong, how can I create an network that can not see anything else but what is also on the same network? The host and the isolated network are 192. and 172. The virtual bridge is not connected (or so it says) to any physical device.

I have 2 different networks: the first one is gateway machine (eth0), and the second is a private machine (eth1). So, I've configured the iptables and forwarding stuff and when I try to ping google.com on the gateway machine, it works, while it doesn't work on the private network. Note: I am using VmWare 7. I need your quick assistance about this issue.

I have a virtual private server that I am trying to connect to using x11vnc. I ran this through ssh to setup gnome
sudo apt-get install gnome-core
sudo apt-get install gdm
sudo /etc/init.d/gdm start
sudo dpkg-reconfigure xserver-xorg
I later ran sudo apt-get install ubuntu-desktop to see if that would help.
Code:
#cat /etc/issue
Ubuntu 10.04.1 LTS
l
Code:
#sudo startx
Fatal server error:
xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory)
I assume this is because it probably doesn't have a video card.

I'm probably dreaming, but I have a hobby project in mind that I would like feed I have an opportunity to purchase a 3 year old fully populated (14 x 3Ghz dual Xeon nodes) IBM bladecenter relatively inexpensively.I thought it would be fun to set it up as a beowulf cluster with open source xen and test the market to see what people would pay for Private virtual machines.
My thoughts are to use 64 bit Centos 5 as a base to get the beowulf cluster up and then load xen.I haven't really looked at the market but I figure I should be able to run 50 private virtual machines charging say $50 per month. I figure I can use rsync to backup the virtual machines to a different location. I plan to connect to linux based Network Storage running 3 x sata 1TB drives, probably via iSCSI. Along with the drive capacity currently on the blades I should get 2-3Tb online capacity over a Gbit network. (Cisco 14 + 4 network switch module)
I realise I have a bit of setup work to do and before I go investing a lot of time and a little money I'd appreciate some pragmatic advice as to why this may be a stupid venture.

I recently purchased a Dell Vostro v130 which came with Win 7 pre-loaded. I've been using it for a few weeks with no problems, but now I'd like to install ubuntu studio. I made it through the the partitioning part but now I'm getting a networking error: "Network autoconfiguration failed. Your network is probably not using the DHCP protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly."
I've been using the wireless connection in win 7 without any problem so I don't know why I'm having a problem now.

I've been trying to understand how Linux creates the network/interfaces on a machine (been reading the Linux admin guide), but as I'm pretty new to this subject, I've got lost in the forest.
To provide with my goal:
1.) Learn about network setups on Linux
2.) Be able to maintain my own (virtual) network
3.) Configure my (virtual) network

I have a server that is on both a standard network and a virtual network, as follows: server1 attached to standard network server1 acting as Dom0 with two linux DomU guests (under Xen) I only have one network card. How do I configure server1 to have a different hostname on the standard network than on the virtual network? Here are the relevant network configuration files for server1:
/etc/sysconfig/network-scripts/ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=none
NETMASK=255.255.255.0
IPADDR=192.168.122.9

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).
As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message
Quote:
Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0
If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.
If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.
Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.
Does anybody have an idea how to enforce that the vpn connection is actually used?

after upgrading VirtualBox from 3.0.x to VirtualBox-OSE-3.1.2-1.fc12.x86_64 VBox fails to start any virtual machine with error: Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_SUPDRV_COMPONENT_NOT_FOUND).
When I run
sudo /etc/sysconfig/modules/VirtualBox-OSE.modules
I get
FATAL: Error inserting vboxnetflt (/lib/modules/2.6.31.12-174.2.19.fc12.x86_64/extra/VirtualBox-OSE/vboxnetflt.ko): Invalid module format

Kernel is (obviously) kernel-2.6.31.12-174.2.19.fc12.x86_64, but same thing happens with any installed kernel, IE kernel-rt-2.6.31.12-1.rt20.1.fc12.ccrma.x86_64
I reinstalled VBox and kmods got rebuilt but the problem persists.

It's been awhile since I posted anything which is a good sign my install has been working well and I have been able to handle most everything. However, I'm not able to handle this issue. I recently installed F11 and everything went well. But, when trying to see my other computers on the local network, I cannot. I receive this error message: Unable to mount location Failed to receive shared list from server. I understand the message as it is obvious, but do not know how to fix it.

I have a laptop with no bluetooth on it.So i bought a bluetooth dongle.It works flawlessly under windows but i am having a problem with it under Ubuntu (As well as other Linux distros). As soon as i plug the dongle i see a bluetooth icon in the Notification Area.
When i click on it and choose setup new device....its scans and shows all the bluetooth devices like my Nokia 5800 xpressmusic cell phone but when i try to pair it simply fails....
I have tried all the Pin codes available and even tried the custom pin option but still no success. By the way right now i am using Ubuntu 10.04..i have also tried it with other linux OS but still the problem remains....

I've been learning linux for a while now with half an eye on making a career out of it in future. One sizeable gap in my knowledge at the moment is networking. Is it feasible/desirable to set up a network of virtual machines to use as an environment to learn networking? My budget is non-existent so I was hoping to be able to get a basic understanding of the principles from installing a few desktops, a virtual gateway etc on VMware workstation on my laptop, and doing a lot of reading online.
Is this feasible, or will I just end up learning about virtual networks instead of real ones? Also how much power would be required, because my 3GB RAM lappy has just gone bang and all I have now is a (new) 1GB RAM lappy.

This remote has to be paired without a pin code, which is how I paired it in windows.In Fedora, however, there is no such option "no pin" when using a standard way to connect bluetooth device.How can I pair this remote in Fedora?

I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error:
Authentification has failed.
As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.
