Ubuntu :: Remove 2GB Virtual Drive Created With Qemu?
Jan 23, 2010I installed Windows XP on my system using QEMU as a 2GB virtual drive in my home directory. I don't want to have it anymore, however I can't get rid of this 2GB used space with windows XP. I can't even delete QEMU, because the command sudo apt-get remove qemu tells me that package qemu is not installed. (however it is there, works, and is able to start Windows XP as usual).
How can I get rid of this qemu/Win XP and have 2GB of my home folder available again?

View 4 Replies View RelatedUbuntu Servers :: Created A New Virtual Host In Apache Using Webmin - Doesn't Work ?
Nov 14, 2010I created a new virtual host in Apache using Webmin and am having trouble getting it to work. When I created it, I opted to create the config file as a "New file under virtual servers directory /etc/apache2/sites-available". So now I have a default config file /etc/apache2/sites-available/default and a new one created by Webmin at /etc/apache2/sites-available/webmin.1412323.conf. It seems like the settings in that new Webmin config file aren't being picked up by Apache -- when I try and browse to mywebsite.com it shows my root /var/www folder, not the subdirectory /var/www/mywebsite.
Is there a way I can tell Apache to include the new Webmin config file for the virtual host or should I just copy the directives into the default file at /etc/apache2/sites-available/default? It seems like Webmin should automatically configure Apache to work with any newly generated config files.
Fedora :: Mount .img File Created By Virtual Machine Manager.
Jan 19, 2010I have a file that was created in Virtual Machine Manager and I need to get it out of the virtual operating system(windowsXP). Writing to a USB would be ideal but that hasn't been working since I upgraded to Fedora12.Is there anyway I can mount the image to retrieve the file?wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so mounting as fvat doesn't work either.

Aug 25, 2009When I create virtual ethernet interface and do a ping -I <v_int> <host> the outgoing address is the one of the physical interface and NOT the virtual interface.Is there no chance that trafic will go out with virtual interface address??Incoming trafic is done well i.e. responds to the virtual interface have the virtual address.
My problem is that I have 2 modems and want to check both default gw behind the modems.
If I do a "normal" ping both are reachable over default route even the modem which is not the default route will not work because ping goes over the working modem.So I have 2 routing tables and want to route the virtual interface to one modem the other to the other modem
Ubuntu Networking :: Created Wireless Network Invisible
Aug 14, 2010I go up to the panel and click on the wifi manager, create a new network and name it "loganspc" with no authentication since previously created networks didnt work with those settings. Now before, I used this in conjunction with my eth0 connection so i could give my ipod internet. then i got a wireless router to do that. its exhibiting the exact same problem. Both the router and my laptop's network are invisible. I create it and then i cant connect to it with my ipod. I do a wifi scan (with an app, its jailbroken) and it doesnt find it still. nor does it find the routers network.

Ubuntu Networking :: Connecting To A Wireless Created By An Apple Computer?
Sep 18, 2010I am trying to connect to an apple computer wirelessly to get access to the internet.. If no encryption is used on the network (gateway?) set up by the apple computer I can connect just fine and browse the internet.
-If a WEP encryption is introduced I cannot seem to connect... even though the WEP keys are identical.
-I have tried both WEP 128 passphrase and WEP 40/128 key... -Have tried the WEP passphrase being both just numbers in case that mattered.
Ubuntu Networking :: Java Socket Connection Created In More Than 3 Minutes
Mar 7, 2011I'm running Ubuntu 10.10. I have a problem with any client side network communication from any java based program/application. I've tried to run the following code:
Code:
public static void main(String[] args) throws Exception {
long start = System.currentTimeMillis();
Socket s = new Socket("ubuntuforums.org", 80);
System.out.println("1. connection created in "+ (System.currentTimeMillis() - start)/1000.0 +" s");
s.close(); start = System.currentTimeMillis();
s = new Socket("ubuntuforums.org", 80);
System.out.println("2. connection created in "+ (System.currentTimeMillis() - start)/1000.0 +" s");
s.close(); }
The result is the following:
Code:
1. connection created in 189.31 s
2. connection created in 0.085 s
I've tried both java-1.6.0-openjdk and java-6-sun-1.6.0.24 with almost the same results. During the extremely long 189 seconds, the processor is doing almost nothing (java thread has 0 %). I've tried also a wireshark to check what is going on, but the first packet was released after those 189 seconds. There is nothing in log files, I have no exceptions or errors, and the connections work (after the first long delay) just fine.

View 1 Replies View RelatedUbuntu Networking :: Files Created In Samba Are Locked From Nfs & Vice/versa
Mar 2, 2010I have just recently setup our network with an Ubuntu server which is being accessed by one Ubuntu workstation with nfs, & one XP workstation with Samba. Following instructions from the web, I set permissions like this:
sudo chmod 777 /media/Data sudo chown -R curley:curley /media/Data The problem is that files created in Samba are locked from nfs & vice/versa. I am assuming I need to add the nfs network share to the Curley group or use something more global than curley to make this work?
Samba is working ok from Ubuntu when browsing through Nautilus, but there is no access to shares when doing things like uploading or downloading files to the web (the "save file" window only shows local folders). So I guess I wouldn't mind just using Samba if I could map a folder in Samba to solve that problem.
Ubuntu Networking :: Can't Connect Wireless Connection On Adhoc Created In Windows 7

CentOS 5 Networking :: Ifcfg-eth0.bak File Created By Kudzu In VMware Clone Of 5.3
Jul 12, 2010I run a VMware clone of CentOS 5.3, I observe that kudzu [i.e. /etc/init.d/kudzu, from /etc/rc3.d/S05kudzu or /etc/rc5.d/S05kudzu] detects a MAC address change on eth0 and then creates a /etc/sysconfig/network-scripts/ifcfg-eth0.bak file. This .bak file is identical to the original ifcfg-eth0 file except for the value of the HWADDR [i.e. MAC address] parameter. I would be unconcerned but for the fact that /usr/bin/neat indicates that both ifcfg-eth0 AND ifcfg-eth0.bak are 'Active'. The following solution may help others with the same (or similar) problem:

View 2 Replies View RelatedNetworking :: Feasible / Desirable To Setup A Network Of Virtual Machines To Use As An Environment To Learn Networking?
Nov 18, 2010I'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.

Ubuntu Networking :: Ssh Tunneling To Virtual Machine?
Mar 6, 2011I am a linux beginner and dont know that much about networks! I have access to a linux VM. The machine is remote and i access via putty. If i can access this machine via SSH and putty, is there any reason why i should not be able to use ssh tunnelling to connect to a vnc server?
I don't know the details of the server and what firewall is set up but i believe that tunnelling uses port forwarding over the ssh connection that is already set up. Where does the port forwarding actually occur? At the actual linux VM or on the router the VM is connected to?
Ubuntu Networking :: Samba Performance On Virtual Box
Aug 1, 2011I have a WinXP virtual box and have setup a Samba server to have it use directly a couple of directories on the Linux side. The Samba performance is definitely better than the built-in shared folders of the virtualbox, but there is nothing to write home about either: transfer seem to top at around 3Mbyte/sec.
The machine is a laptop (Core i5 CPU (M520@2.40GHz) and a 7200RPM HDD) running Kubuntu 10.04.The Samba share uses a dedicated "host-only" network adapter. There is an iptable-based firewall to which i added the required 4 statements to let the Netbios traffic go through (without them nothing works...)So, given the hardware, are the 3MB/s a decent figure? And if not, what should I aceeive, and where can I look improve on the current numbers?
