Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu.
I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.
I am trying to set up samba in my CentOS virtual machine that is running on a Windows 7 host. I have found a tutorial in the How-Tos on this site but I'm not sure if they are exact and I'm paranoid about messing something up. The link to the tutorial is below. Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines? Please note: I am very inexperienced in the IT field. [URL]...

With fc12 vpnc starts allows me to connect to my work site then everything works fine til I try and start a remote desktop connections to a windows client use tsclient. All I get is a blackscreen and my laptop is hung.
At work without the vpnc it works fine if I start the vpnc from nm it performs the exact same way and I get the blackscreen.
I have disable selinux.I also disabled the firewall
there was another gentlemen on here with the same issue.
The only way out is a hard reboot and there are no messages in the logs that say there were any problems.
I've been trying to connect to my office Cisco VPN several time using the network-manager-vpnc GUI in Ubuntu Karmic with no success. I read a couple of articles and i tried using the direct command line way:
Code:
sudo vpnc office
with the following /etc/vpnc/office.conf file:This is fictional data
Code:
IPSec gateway vpn.office.com
IPSec ID office
IPSec secret 0ff1c3
which worked perfecly.
So i went back to the Network Manager GUI way and i used the same credentials. Same fictional data I got a libnotify message telling me it couldn't connect.Anyone know how i could troubleshoot this issue? Would be great to have it integrated in gnome instead of running a background command which is not tracked by nwm.
Should I use XEN or VirtualBox to host linux on windows 7 or windows 7 on linux? Since I've read about the problems of reading/writing NTFS disks with linux usnig the Linux NTFS driver, I thought it would be better to host windows on linux. I think the problem is that you never can be sure if the linux NTFS driver is going to corrupt your disk because Microsoft does not publish the format for linux developers.
By running windows on linux, I could read and write EXT3 from windows. I think there are EXT3 drivers for windows. Then I got to thinking: If I am running Linux on Windows, am I going to be using SAMBA or the linux NTFS driver? I think I'm going to be using SAMBA to read and write the linux partitions -- correct? Are there other considerations when deciding to host linux on windows or windows on linux? I'm going to using both the linux and windows partitions for software development with java/eclipse and various databases including oracle.
What is the best way to share files in virtualbox between host/machine I thought of trying usb but the devices are all greyed out. I know the fix for this but I have to search for it, permission problem I think? Or is there a more elegant way
View 4 Replies View RelatedI would like to share a folder from a Linux Guest with a Windows host (with read and write access if possible) in VirtualBox. I read in these two links: here and here that it's possible to do this using Samba, but I am a little bit lost and need more information on how to proceed.
So far, I managed to set up two network adapters (one NAT and one host-only) and to install Samba on the Linux guest, but I have the following questions now: What do I need to type in samba.conf to share a folder from the Linux guest? (the tutorial provided in one of the links above only explains how to share home directories) Are there any Samba commands that I need to run on the guest to enable sharing? How do I make sure that these folders are only available to the host OS and not on the Internet? Once the Linux guest is setup, how do I access each of the individual shared folders from the Windows host? I read that I need to mount a drive on Windows to do this, but do I use Samba logins, or Linux logins, also do I use localhost? or do I need to set up an IP for this?

View 6 Replies View RelatedI 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.

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.
Recently I've been unable to load web pages, hosted on my Ubuntu Guest in Apache, from my OSX Host. In fact, I can no longer even ping the Guest OS from the Host. In the past, when I did ifconfig on the Guest, I got an IP of 10.0.1.n. Now I'm getting 10.0.2.15--the default NAT Address. The thing is, I didn't change any settings recently. What I did do is run software update for OSX, Ubuntu, and updated VirtBox.
Current Versions:
VirtBox 4.0.8 r71778
Host: OSX 10.6.7
Guest: Ubuntu 11.04
why I can no longer access my Guest OS from my Host? I spent hours on this last night, to no avail. What would cause the Guest IP to change from 10.0.1.n to 10.0.2.15? As I say, I manually made no config changes.
Debian Testing host, Winduhs XP guest. Winduhs is not allowed to directly access The Internets, and I am not setting up bridging as that makes it possible for the guest to mount layer 2 attacks on the LAN. I need for the guest to tunnel through the host without being able to see anything on the host, so it can then get access to The Internets, while being protected by iptables (Shorewall).
Used to be with VMware I had host-only set and the guest in a different class c (192.168.2.1) from the host (192.168.1.1) I turned on ipforwarding, set Shorewall rules, and it all worked. Now I have everything set with VirtualBox, and it does not work. Guest can ping its interface but not host. Host can ping vboxnet0. Host is supposed to masquerade guest's 192.168.2.1 through to the default out at 192.168.1.1, but it's not. I think a clue is in routing, but I don't know what's wrong.

It hangs at the end and I can see in /var/log/messages "modem-manager: (net/tun0) could not get port's parent device" and then eventually "withdrawing workstation service for tun0".
My settings are correct and other people seem to be able to connect.
I am not using KNetworkManager because of an issue on my machine regarding rfkill.
As of yesterday I have this perculiar problem. When I try to ssh into my account I have on a linux server where I keep some of my files (I'm using Cisco VPN) ssh claims it can't find the address.It's worked fine before, and if I connect using putty in Virtualbox on the same machine it works.The problem applies both to command line ssh and NetBeans (which uses a java client).I've tried setting SSH not to resolve DNS in the config file but it doesn't help.

i have a udp server running at port 60178. when i connect to it from localhost there is no problem. when i use the client from a remote host i am not able to connect.

View 3 Replies View RelatedTrying to set up a VPN connection from with Virtual Windows XP (virtualbox) and the network shows verifying user name and password but then times out and give me a message that it could not connect to the serve.
Since I could connect from a Windows system at another location, I assume there is something in Ubuntu that is preventing the connection so I tried to set up a VPN connection in Ubuntu.
I installed "network-manager-pptp" and "pptp-linux" as mentioned in the documentation but when I try to create a VPN connection using [main menu]>[System]>[Preferences]>[network connections] the VPN tab has a padlock on it. I set up the VPN but did not put a DOMAIN name on it because the server does not have a DOMAIN and it did not appear to be necessary on the dedicated Windows machine.
In spite of configuring the VPN connection, I cannot find the connection anywhere so I can see the server at the other end.
When I try to use [main menu]>[places]>[Connect to Server] using [windows share] and enter the IP number of the server, I get the message "Cannot display location smb:// {server IP address}"
And if anyone knows why the Virtual windows cannot connect.
I have made a fresh install of Ubuntu 10.10 and installed Virtualbox from the repository Virtualbox runs ok.

Is there any way to resolve the hostnames of windows machines from linux systems.My environment is 80% windows and 20% linux.Domain controller,DNS,DHCP servers are on windows 2003. In linux systems,we just create local user account based on the user account created in domain controller,and give the dns servers ip address in the network settings.Authentication of users will be done locally. how to join these linux systems to windows domain so that authentication should be done by domain controller as well as host name resolution of windows systems and linux systems..

A family member has got a windows PC (with a Pentium 4 w/o hardware virtualization support) that keeps winding up infected and crudding up. As I would like to minimize family IT support time, I figured the easiest thing to do was to wipe it, put Linux on it, install XP pro (they don't want a more recent one) in a VirtualBox virtual machine, and take a snapshot. I'd set up a shared drive on the host where they could store all their stuff, so that when it inevitably gets hosed, all I have to do is roll back to the snapshot.
This leaves me with the question - which host distro would be the best choice? I'm looking for three things - ease of maintenance on my part (updates, configuration, etc.; I have a background in slackware, but have some exposure to Ubuntu), minimalism (so that the bulk of the system's resources can be devoted to the VM), and virtualization-readiness (say, so I can have the computer automatically go from power up to virtual machine power up, thereby minimizing the user exposure to the host).
Obviously, I would like it if it has all of the standard tools that will allow me to do remote maintenance, also.
I've looked at Ubuntu server JeOS, and it seems enticing, but I can't seem to find out whether it can be used on a desktop system, i.e., with a GUI, etc.

I use VPNC to connect to a Cisco VPN. I am able to connect, but some issues exist when I use SSH. For example, I login through SSH to a computer in the VPN and I execute ls => it works. If I execute ls -la => connection stalls. I think it stalls every time it is supposed to return more content (top, ls /etc).
If I do scp from my end to server => works. If I do scp from server to my end => connection stalls.
I'm trying to setup a VPN using VPNC. All is well and I can create the VPN.
The problem is that CNTLM does not want to connect in the VPN Further more I am not sure what to look for? The logs are empty and CNTLM only reports 502 Parent proxy unreacheable.
How can I trace what the problem is?
My setup:

dmesg gives me nothing. I have scoured the web .. and even asked on #vbox and #fedora cant get.
I have tried a few times already the following procedures: start a new installation (each time, I create a new VBox VM) with the Fedora 12 DVD iso attached to the DVD drive of the VM. I select the default setting, like US english, US keyboard, local time (GMT +8), standard installation ... etc). The installation process had been smooth to the screen the system asking for a reboot after installing something like 1100+ packages. Then I click the reboot button offered. The VM restarted but each and every time, it came up with the following error message:
Booting from local disk...
FATAL: INT18: BOOT FAILURE
There was no other error message durint the installation process. It would be very much appreciated if some one can tell me what went wrong and how to solve it. I believe even I try again the same way, it will end up with same result. Is it a software or hardware problem? In case software problem, is it Fedora or VirtualBox?
