How to Transfer Data or Files From Computer to Computer

Have to easily connect to another laptop wirelessly to help you move some data with no switch or Internet connection? Lacking any Internet connection, you can’t use syncing companies like Dropbox to talk about information between devices quickly. For those who have a network system just like a hub, hub or transition, you may get the computers to speak with eachother, but it requires a great deal of additional function (filesharing, permissions, firewall configurations, etc).

However, if you have a laptop or computer that’s an invisible card and thus does your friend, you can use the cards to create a wireless connection between your two computers. When they are connected wirelessly (also called a peer-to-peer ad hoc wireless network), you can easily share knowledge between your computers. best laptops below 1000

You can make an ad hoc network in Windows or in OS X as well as in this report I’ll explain the measures for producing the network for every OS. It’s important to observe that ad-hoc networks in general have certain constraints which make them only ideal for certain conditions. Firstly, the pace of an adhoc network is normally less than that of a standard infrastructure network. Ad-hoc network features just require a max-speed of 11Mbps, that is way slower than b/h/n/ac max speeds.

Secondly, you can’t check signal strength of ad-hoc networks, so that you must ensure the computers are reasonably close to eachother and don’t move alot. Finally, adhoc networks don’t help all of the safety attributes of normal infrastructure networks, to allow them to become more easily compromised.

Establishing an ad hoc Network:

This guide will be published for Windows 7, however you can follow the exact same instructions for Windows-8 and Windows Vista. To begin with, start the Control Panel and click System and Sharing Center.

  1. network sharing center
  2. Around the next dialogue, click the Setup a fresh link or system link towards the underside.
  3. setup new connection
  4. In the new connection dialog, scroll down until you see the Setup a radio random (computer-to-computer) network option.
  5. setup wireless ad hoc

To the next screen, it’ll describe exactly what a ad hoc wireless network is and will inform you that when you’re currently attached to a radio system, you’ll probably get disconnected. Go on and click Next.

  • new random network:

Now you’ve to provide the system a title, select a security type and provides it a security key. For your security key, you may select from just three alternatives: no certification, WEP or WPA2-Personal. The standard is WPA2-Personal, which can be the strongest. Press next after which you’ll get a screen showing you that the community has been setup. Observe that should you don’t check the Save this network pack, as soon as you remove in the ad hoc network, it will simply disappear. If you prefer to use it again, you’ll need to start from scratch.

  • network setup

Congrats, you’ve finished the primary part! Go ahead and start your set of wireless networks and you should see your newly created one listed along with the rest of the wireless networks. Click it to connect.


i have abandoned Lubuntu or LXDE…

what little is saved in space and processing is not worth the sacrifice to the proper functioning of the OS…


lubuntu networking notes

hotplug is your friend if you want to use lubuntu network manager and you don’t want the manager spinning all the time.

why even use network-manager?

because you don’t want annoying failsafe timer messages on bootup (main reason)

if you attempt to # out timer messages in failsafe.conf you will cause more headaches for yourself.

to check nm device management

ccie@ccie-virtual-machine:~/os$ nmcli device status
DEVICE     TYPE              STATE
eth2       802-3-ethernet    connected
eth1       802-3-ethernet    disconnected
eth0       802-3-ethernet    unmanaged

this is especially important if you are using more than 1 network virtualization environment and you have a default network config supporting a primary, like virl in my case:


for each vm you’ll want to customize internal networks as needed.

#The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet manual      # set pass through and use br0 for networking

# Bridge setup
allow-hotplug br0
auto br0 
iface br0 inet static
  gateway    # make sure this gateway address is correct
  bridge_ports eth0        # bind to device here
  bridge_stp off 
  bridge_fd 0
  bridge_maxwait 0

kvm/qemu/vmware notes

make qemu image container

qemu-img create -f qcow2 /var/lib/libvirt/images/exos.img 10G

apply parameters to image container

qemu-system-x86_64 -hda /var/lib/libvirt/images/exos.img -boot order=d -cdrom /home/ccie/os/exospc- -enable-kvm -m 1024M   -cpu host

 disable pxe boot edit vmx and add for each e1000 int:

ethernet0.opromsize = “0”

virt-install (replace parameters as needed)

sudo virt-install –connect qemu:///system -n vm10 -r 512

–vcpus=2 –disk path=/var/lib/libvirt/images/vm10.img,size=10 -c /var/lib/libvirt/images/CentOS-5.6-x86_64-bin-DVD.iso –vnc –noautoconsole –os-type linux –accelerate –network=bridge:br0 –hvm

sudo virt-install –connect qemu:///system -n vm10 -r 512 –vcpus=2 –disk path=/var/lib/libvirt/images/vm10.img,size=12 -c /var/lib/libvirt/images/CentOS-5.6-x86_64-bin-DVD.iso –vnc–noautoconsole –os-type linux –accelerate –network=bridge:br0 –hvm

cli vmware tools install
first go to vm-manage and reinstall, select reinstall. a pop up comes into the vm. then mount
sudo mkdir /mnt/cdrom
sudo mount /dev/cdrom /mnt/cdrom
mount point is /mnt/cdrom  vmtoo.tar.gz should be there
cd /tmp

sudo tar zxpf /mnt/cdrom/VMwareTools-10.0.5-3228253.tar.gz

umount /dev/cdrom

cd vmware-tools-distrib

     sudo ./ -d -f
to accept the defaults w/o being prompted and to force install because sometimes it hangs

uuid generation for kvm
sudo apt-get install uuid
ccie@ccie-virtual-machine:~$ uuid
create a bridge for kvm
 sudo brctl addbr br0
configure the bridge in /etc/network/interfaces
this will cause br0 to assume eth0’s address
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_fd 0
sudo /etc/init.d/networking restart, or reboot
make an empty  image file
sudo qemu-img create -f qcow2 /home/ccie/images/ubu-client.img 10G
Now you are ready to start a VM using the domain XML file you created earlier. The following command will create a VM, and automatically start it.
$ sudo virsh create ubu-client.xml
from img create
ccie@ccie-virtual-machine:~$ sudo qemu-img create -f qcow2 /home/ccie/images/ubu-client.img 10G
