Gawk provides built-in networking support. The gawk manual has some examples, for basic UDP-communication at . The classical sender/receiver code snippets are as follows:
print strftime() |& "/inet/udp/8888/0/0"
"/inet/udp/0/localhost/8888" |& getline
Unfortunately these examples did not work on my test system under Ubuntu 13.10 Desktop 64bit and gawk v. xxxxx. Ref.  provided the correct description of the fields of the network strings. Using that, my working versions are:
#! /usr/bin/gawk -f
print strftime() |& "/inet/udp/0/localhost/8888"
#! /usr/bin/gawk -f
"/inet/udp/8888/0/0" |& getline
According to , the full syntax of the special file name is:
Replace “localhost” with the IP address of a remote machine, if receiver and server are not running on the same machine.
From the official documentation it is not very clear, how to install the guest additions necessary to use shared folders. Here’s how it works:
VirtualBox Guest Additions is a .iso file, that can be downloaded from here (for version 4.6.3): http://download.virtualbox.org/virtualbox/4.3.6/ The file in question is “VBoxGuestAdditions_4.6.3.iso”. Download it and burn it onto a CD. Boot your guest OS in VirtualBox and then insert the burned CD. The installer should start after the CD is recognized.
Tested with: Windows 7, Windows XP
