Hi All
I'm trying to bring virtual guest from headless mode to gui mode in VirtualBox. But I don't know how to do it. I really appreciate if someone help me on this.
I usually run linux virtual machines in headless mode and connect to it through ssh. I have setup tigervnc-server on linux virtual machine, so that i can connect through vncviewer whenever i want to work on gui.
But recently, one of my friend said, I can also start virtual machine in headless mode in VirtualBox window by holding <SHIFT> key and press Start. Sure it did, it started in headless mode. But, now I don't know how to bring back window again.
Thanks you.
Hello,
Host machine: Windows seven 64 bit
Guest machine on Virtual box: Oracle linux 6.5(64 bit)
If there are multiple files sourced, each containing many variables,and each in a location not known to the person using a user,
is there a way to know the file name where the variable is set?
Many thanks
Hi there everybody,
I am getting really frustrated on a far to trivial problem. I am running ubuntu in virtual box on a windows 7 64bit machine. By default the screen has a resolution of 640x480 and thus only shows the upper left corner of the actual screen, meaning I can't see the entire screen. I was able to figure out, that I have to install guest additions but as soon as I go to devices -> install guest additions I get an error, that the medium couldn't be placed into the drive. It further asks me whether I want to force it to be mounted but if I say "yes" nothing else happens.
Any chance there is a simple way to solve this problem or is this really such a complicated issue?
Furthermore I would prevent linux from going into standby. Actually the settings say, that it will never go to suspend but it does so after it wasn't used for approx=. 5minutes or so.
Thank you guys very much for helping me getting rid of my newbeness :P
Hi all,
I am brand new to Linux, playing around a bit with different things to see how I can use it in the future. Here is my problem:
I have written a simple program in Ada that works well on windows. It opens a TCP port (20000) and listens for incoming connections. I tried it on my internal network and it works well. I can connect from other windows machines and even from my Linux machine.
Now I moved the program to Linux and compiled it there. It starts ok and then listens for the connections. I can connect to it from that same Linux machine but not from any other machine on my network.
I checked the firewall status on Linux with ufw status and it is disabled. I also tried to add a rule to the iptables with
iptables -A INPUT -p tcp --dport 20000 -j ACCEPT
but still nothing. I can not connect from another machine on my network. I also tried to open a simple telnet connection from a windows machine and that too is blocked. I thought without the firewall all incoming connections would be allowed but obviously something is not working as I thought.
Any help would be greatly appreciated
I have VirtualBox up and running on my headless Centos 6 machine, am using http://sourceforge.net/projects/phpvirtualbox/ as a GUI, and created a virtual machine and installed Windows 7 on it.
I can access it using the VirtualBox console (via phpvirtualbox interface), however, only can see part of the screen and the mouse doesn't work properly. I can also access it using Windows Remote Desktop Connection using IP 192.168.1.200:9000 (why port 9000?), but again the mouse doesn't work.
I have the following ext packs installed on the server.
Code:

Do I need additional extensions to better interact with the guest? How are they installed? Thank you

hello Experts!
need some help here with python FTP. so what i'm trying to do is, from a linux machine, ill be sending over a python script to a windows machine via python ftp. that works fine with no problem. now, i want to execute that python script i sent remotely. im having trouble with that. here's my code to just execute the script:
p.s : please dont suggest other options such as python paramiko due to many network security reasons
Code:
ftp = ftplib.FTP("windows machine name")
ftp.login("username", "password")
ftp.cwd("where\\python\\script\\is kept\\")
ftp.sendcmd("python myscript.py")
but looks like it doesn't recognize that command. how do i accomplish this please?
Want to format a 1 TB Western Digital drive in an old dell 32 bit machine. Machine has Lubuntu installed and a Virtual machine on which which is loaded Windows 7 (32 bit).
Machine does not "see" the new 1 TB (SATA) drive after I physically install it in the machine.
I have other windows and Linux machines. I have some drive cradles in which I can connect to (windows) USB ports.
Is it possible to use the old Dell machine to format the new drive?
(It appears that this question has been answered before. So I will check those materials as well.)
Thanks for any assistance.

There is a home grown application that initiates either a telnet or ssh session based on the number of threads set.
I want to watch the process happen from start to finish, that is from the moment the first thread starts until the last thread finishes.
I was thinking netstat, but it wont show the process in its entirety. As connections are established and terminated the status / output of the command would be different..not to mention Id have to keep hitting the command and the enter key.
As usual, I have cracked my Linux in a nutshell book and will be doing web searches to find a solution.
