PuTTYcyg is a patched version of PuTTY that, in addition to telnet,
rlogin, ssh, and serial connections, can also be used as a local Cygwin
terminal instead of the Windows console or xterm.

PuTTYcyg is available at: http://code.google.com/p/puttycyg

The PHP version comes with CentOS 5.x is 5.1.6. To update it to the latest version, follow the instruction at http://www.jasonlitka.com/yum-repository/ and then type “yum update php”

Using command option -mno-cygwin to compile a C++ code on Cygwin makes it runnable not only on Cygwin but also on native Windows/DOS environments.

yum search …

yum install …

yum remove …

yum groupinstall “KDE (K Desktop Environment)”

During my installation of a CentOS Linux guest OS on my Windows XP host system, I found most steps are pretty straightforward according to the manual, but there are a few places costing me some time to do research on Google.

1) To install the guest addition kit, I have to find and mount the image file VBoxGuestAdditions.iso under the virtualbox program root folder, but then I met this error when running “sh VBoxLinuxAdditions-x86.run”:

Guest Additions installation
Please install the build and header files for your current Linux kernel.
The current kernel version is 2.6.18-164.el5
Problems were found which would prevent the Guest Additions from installing.
Please correct these problems and try again.

After trying multiple solutions on Google, the following solution worked for me, i.e, by running:
install kernel-devel-`uname -r`

2) X-windows size is too small, maximumly only 800×600. After adding the guest addition, I am able to either modify the display file “/etc/X11/xorg.conf” under Section “Screen” to add a new Modes “1280×1024”, or directly use the System -> Display tool: under the Hardware tab, select LCD monitor type and then under the Settings tab, choose the right Resolution.
