General :: How To Configure Serial Port Of Virtual Machine With Host Machine?
Jul 29, 2009
I successfully installed the virtual box on my fedora 8 system, and also created a virtual machine with windows xp OS, it works nicely, I try to configure the serial port of my virtual machine and try to configure the path for the port "screen shot are attached" it gives me the error message also the "screen shot are attached" for your review.Is kind of mistake is going on during the path setting, and how to set the path for configuring the serial port of my virtual machine so that I can use the hyper terminal tool of windows.
I have to connect from my linux client laptop to SPARC machine by using roll-over cable and RJ45 interface on the server. On windows I always used Tera Term but don't know how to accomplish this task from linux laptop.
Is there some kind of app like TeraTerm on linux too ?
ok how do you add a rule which allows a virtual machine to connectto ssh on the main fedora host?so connecting from a virtual machine to the main fedora host installation? I think i have to use an iptables command but not really sure
How can I connect to Linux (which is in a VM) from the host PC using putty? I can ping the 192.168.1.108 from my host PC. And there is sshd process running on Linux. I choose the SSH to connect, but gives error.
Will there be any issues installing and then subsequently running a Microsoft Windows Server 2008 R2 installation on a VirtualBox VM on a Linux host (Ubuntu 11.04 64-bit)? I require Windows Server 2008 R2 for a course I'm taking, and I dont have any systems to install/deploy it onto.
Host Machine Specs:
Ubuntu 11.04 64-bit 4GB RAM 350GB Disk Space Nvidia Quadro system
I have cloned an embedded system that runs Opensuse 11 x86 using dd. The embedded system uses a simple serial device, by writing to the relevant device file (/dev/ttyS2, usually). Curiously, when I write to the same serial device on the newly cloned system (which, incidentally, has almost identical hardware), thusly:
echo hello > /dev/ttyS2 the command blocks for up to a minute, before finally returning without making the hardware do anything. I can boot into Opensuse's rescue system on the clone and successfully do exactly the same thing, as I can when I boot the original's "identical" operating system. Why might this problem occur? What can I do about it?

I am currently running ubuntu on a qemu-kvm virtual machine, and the host is fedora. I would like to mount a folder of the host machine on my VM, but never succeeded. The result of the command is :
root@armnlib-kvm:~# mount -v 192.168.1.10:/nfs /nfs mount: no type was given - I'll assume nfs because of the colon mount.nfs: timeout set for Thu Jul 7 06:02:43 2011 mount.nfs: text-based options: 'addr=192.168.1.10'
I'm trying to ssh into a virtual installation of ubuntu I have, named "ubuntu-x86" but I can't get it to work for some reason. I have two network cards, both assigned to NAT, on the virtual machine, but one has a static IP address, while the other uses DHCP. For some reason, the command:
I couldn't find a clear answer to this, but is the linux-image-virtual package for host machines that will contain VMs, or a VM-oriented kernel for guest OS (ubuntu)? I have some guest VMs running on Microsoft's Hyper-V, and was looking for some further optimizations.
I've installed VirtualBox OSE and have a couple of guest OS setup. I am running Ubuntu 11.04 and VBOSE version 4.x (the most current). Now this installs the guest OS virtual harddrives to a folder in my home directory. How do I get other users on the same host machine access to those virtual machines within VB? Currently logging in as another user and going to Applications/Accessories/VirtualBox OSE ... the list of guest machines is empty save of course on my login.
How can I run LAMP (Linux, Apache, MySQL, PHP) in a virtual machine (Ubuntu in virtual box) and make it so the web server is accessible locally (and ONLY locally) on the host OS via an ip address?
I have installed CentOS on a VMwareWorktation and that CentOS, i also install VMware Server (suscess) and setup a guest OS that, but i start this Guest OS, an error show "You may not power virtual machine in virtual machine"...
I have a WindowsXP virtual machine which I need to isolate from the host machine completely (have the host act as a bridge but not be visible on the IP layer at all.) It still needs to have Internet access. Obviously it has to be able to contact the router but I would like to be able to block port 80 (or even just block all SYN packets addressed to the router.) I also want to allow port forwarding from the router to the virtual machine. I can use basic iptables but this is way beyond me.
The host OS is probably going to be Debian Lenny but this is not built yet so if someone can recommend a different distro which is as lightweight as possible but will support VMWare, iptables and tcpdump then that would be great. I was thinking of Slackware but I have not used it in ages and from what I can remember their is no real package management.
I read once that you could use VMWare's converter to convert a physical machine into a virtual machine to run in VirtualBox. Can someone point me in the direction of a tutorial or just give me instructions on how to do this? I was very confused by the converter and how to get the image to work with virtualbox.
I have ubuntu-8.04.1-server installed on virtual machine. It works perfect. Now, I made copy of this virtual machine. I started that copied machine and it works fine, except one thing: network does not work! I have several others VMs with freeBSD, openBSD or Windows on it, but only ubuntu machine hes network problem after coping. I tried some other VM with ubuntu on it - same problem! I downloaded VM with ubuntu - same problem.I take a look into /etc/network/interfaces file and it looks just as it should (same as before coping) but ifconfig command returns parameters for lo only (before coping there was eth0 and lo).
I'm working on a script. fter it has installed and removed packages, I need to configure a ton of settings. In GNOME, I understand that those settings are kept in "/home/user/.gconf". Can I create a virtual machine and configure the system through the GUI to my liking and then dump all of the settings, so that I can load them on another machine? Is it as simple as copying the directories?
I'm trying to setup and configure a server entirely with text only run mode 3 on a virtual machine so I can redo my current live server. I'm now trying to set up the firewall of the system using iptables. I've read up on it and came up with the following:
-clear all rules #iptables -F -set default policy rules #iptables --policy INPUT DROP #iptables --policy FORWARD DROP
[Code]....
Everything above worked for me but just out of interest I looked at my live server which was configured using a GUI. I ran iptables-save and it was pretty much the same but its port open lines read like this:
#iptables -A INPUT -p tcp -m state --state NEW --dport 80 -j ACCEPT
so finally my question is do I really need the "-m state --state NEW"? Wouldn't having that drop established connections on those ports? I'm just confused as to what exactly the NEW state is doing and would it make a difference if I didn't include it.
I'm currently working on a project for university that requires communication, via an RS232 link between a piece of hardware (I have designed and am currently testing) and some software(which need testing).
I was hoping to have my hardware finished by now so I could get on with testing the software over Easter.
The hardware does not work yet but I would still like to test the software.
Does any one know if there a way to make a virtual serial port that I could put data on and read data off while my program accesses it as a regular serial port so I can check my code?
I am using Ubuntu 9.10 and am happy to give any more information on request.
I want to create a virtual serial port in Fedora. I'm using Java code to communicate over a serial port. I want to test this code with out any serial devices connected.
Right now I have a machine set up running Fedora. I have configured inittab to accept Console Logins, but I am having problems getting my netbook running PuTTY to connect. How would I go about finding the Host Name and Port to connect to?
Having trouble visualising how IP-Based Virtual Host (with SSL) would work. Here is my vhosts.conf file:
Code: #Define Name Virtal Host NameVirtualHost 10.10.0.54:80 #Used to replace the main server host. The log file will reside in /var/log/httpd/error_log
[Code]....
How will it work? I will need to forward port 443 to the 10.10.0.55 interface right? Without doing that, there is no way this is going to work... is there? And that means that I can't run more than 1 ip-based SSL virtual host on one machine because I can't forward 443 to two different interfaces.
Also, do I use internal ip address or external ip address in the <VirtualHost > tag? I only have one static public ip.
I am looking for c/c++ code (no third party lib dependency) to get the physical address of ethernet card on mother board.Most of them suggests to use the linux commands and process the output. For example "/sbin/ifconfig eth0".The problem with above command is that when you run this on a linux variant which is running using VirtualBox on windows host, it's not returning the correct mac address. In this case the correct mac address is the one set for individual virtual machine."/sbin/ifconfig eth0" works fine when linux variant is installed normally.There is another case when linux variant is installed normally and if you install virtualization apps such as VirtualBox or VmPlayer, they create a virtual adepter for their own use. In that case running "/sbin/ifconfig" returns all the adepters. (physical and virtual)
My poblem: At work I have a proxy with some closed ports. I need to connect to an Oracle DB on some DB_IP at port 1521. DB_IP is a public IP. What I Have: At home, I have a Linux machine and a Linksys WRT54G Router. What I need: How can I do to communicate a PC at work with DB_IP:1521?
How Do I enable a port 843 in a Linux machine . I have written a server program that listens to port 843 and responds when requested . But Client socket request is not able to reach that port . socket.connect functions returns -1 with timeout. I have edited /etc/services to add that port . But this is not working .
In order to get the work done I use a Macintosh Macbook Pro (4,1) with a Boot camp partition running Windows 7.This allows me to use my favorite OS (OSX) with my required work environment (Win7 & .Net) when ever I need them.To allow me smooth usage I use Parallels 5 to virtually boot my Win7 machine from within OSX but whenever I want to do some heavy lifting I reboot into Windows 7 (on boot camp) which allows me to use my laptop's entire resources for my work.
My problem is this: I am now about to begin work for a company in Tel Aviv which uses Linux desktops for development and I need to follow suit. So I've given my self a new Quest: Set up the ultimate web development platform. My goal is this-
1. Install the three operating systems one along side the other - OSX, Ubuntu & Windows 7.
2. Set each one of them up in such a way that allows me to boot into it (meaning I can have any one of these OSs running on its own when I want.
3. Use parallels to virtually boot my Win7 partition - this allows me to keep using Office 2007, which I use often.
4. optional! Use parallels to virtually boot the Ubuntu OS also.
I have managed to complete goal 1 & 2.But I simply can't get 3...In theory it isn't a problem to install windows & OSX along side each other and virtually boot the windows under OSX using parallel's bootcamp virtualizer- BUT - the moment I install Linux along side the other two it break's parallel's virtualizer and it can't boot. I think it is due to parallel's in ability to use GRUB but I'm not actually sure about that.
I am considering compromising and going for a system like this:
1. Install OSX and Ubuntu on the laptop - which means I can boot into each of them.
2. Create a virtual machine for Win7 using parallels.
But that will be a real compromise as far as I'm concerned and I hope to find a way to set up the machine as I described earlier (three OSs which can be booted independently and also loaded in VMs).Just to make sure I'm clear - I HAVE MANAGED to install three independent OSs on the same machine - but that always prevents me from booting them as VMs using parallels...
I have a main Ubuntu system and a virtual Windows system, set up using QEMU/KVM. So, I can start Windows using virt-manager and connect to it using a VNC client.But what I really want to have is a new Xorg display that is connected to this Windows system, so that e.g. CTRL-ALT-F8 shows Ubuntu, CTRL-ALT-F9 shows Windows. That'd be a real alternative to a Linux/Windows dual-boot setup.
I know that GDM had some option to connect to another X server (XDMCP), but I couldn't get this to work with GDM2/Ubuntu 10.4. Would this somehow also work to connect to a VNC server (like the virtual Windows system)? how to make Xorg provide a display for incoming VNC connections, but nothing on how to do the opposite.
What is the a tried and tested free virtual machine solution like VMware for Linux? I would like to run several different types of OS on a server with an Intel processor?
