VirtualBox creates/uses a network adapter named vboxnet0 on the host, when a VM network adapter is connected as "host-only". As the VM starts, VirtualBox assigns the IP address 192.168.56.1 to vboxnet0 on the host. The VM DHCP client grabs the IP address 192.168.56.101 from the VirtualBox DHCP server. Connectivity is limited between the VM and the host - unless you configure NAT and IP forwarding on the host. For OpenWRT, if the DHCP client is not started automatically: #/sbin/udhcpc -i br-lan -p /var/run/udhcpc.pid -s ...

Install the DHCP server: voodoo@newpc:~$ sudo apt-get install dhcp3-server ... Edit /etc/dhcp/dhcpd.conf (this is the minimum for a local network without DNS): ddns-update-style none; default-lease-time ... Start the DHCP server: voodoo@newpc:/etc/dhcp$ sudo /etc/init.d/isc-dhcp-...

The DHCP client packaged with BusyBox is udhcpc . It negotiates a lease with the DHCP server and executes a script when it is obtained or lost. There are four possible arguments to this script: deconfig : The script should put the interface in an up but deconfigured state. bound : The script should configure the interface and set any other relevant parameters. renew : This is used when a lease is renewed. IP address does not change but other parameters may change. nak : This happens when a NAK packet is received from the DHCP server. Network parameters are passed to the script via environment variables. Ubuntu documents that the default script is at /etc/udhcpc/default.script . For OpenWRT, it is located at /usr/share/udhcpc/default.script ....

By default VirtualBox enables one network adapter ("Adapter 1") with NAT. Connection from the guest OS to the outside world works natually when the guest network adapter is assigned an IP address by the VirtualBox DHCP server. Use VBoxManage to see a list of DHCP servers: $ VBoxManage list dhcpservers NetworkName: H... The guest IP address is not visible from the outside world. If you need to access a server on the guest OS, you need to set up port forwarding in VirtualBox settings: Settings -> Network -> Adapter 1 -> Advanced -> Port Forwarding . Beware that on Linux/Unix, port forwarding may not work if you bind to a privileged port (port number < 1024) but you are not root. Bridged networking can be...

You can configure Windows XP such that when you press the "Power" button it goes to standby instead of showdown: From Start menu, bring up the Control Panel Double click the Power Options icon: In the Advanced tab, select "Stand by" for the option "When I press the power button on my computer".

Windows XP has built-in capability for burning folders/files onto a CD ROM. Use the Recording tab in the CD-ROM drive properties dialog to configure the options: However, it doesn't have the capability to burn ISO images. On the MS site it was suggested that ISO Recorder would do the job. I tried it on two different machines and both failed with " generic error ". I'm running Windows XP professional SP2 on both. Update: Actually the above error for ISO Recorder was caused by a monitoring program the company installed to block CD-ROM write access. Although unsuccessful, ISO Recorder actually went further than other programs. cdburn.exe from the Windows 2003 Resource Kit died at 0% without emitting any error message.

MinGW is "Minimalist GNU for Windows" - a collection of freely available and freely distributable Windows specific header files and import libraries that allows you to build Windows native executables with GCC. MSYS is a minimal system that provides a POSIX compatible shell and utilities so that you can run the normal set of GNU build tools (such as configure, make). You can download MinGW and MSYS from sourceforge.net: http://sourceforge.net/project/showfiles.php?group_id=2435 . The set of files is overwhelming and installation is confusing sometimes. But here's what I did in order to build ffmpeg on Windows XP: Download "Automated MinGW Installer" (MinGW 5.1.4) Install MinGW 5.1.4. Select "Candidate". Check g++, but leave other options unchecked Finish installation of MinGW Install MSYS DTK 1.0 in C:\msys\1.0. Download "MSYS...
