PAExec lets you launch Windows programs on remote Windows computers without needing to install software on the remote computer first. For example, you could launch CMD.EXE remotely and have the equivalent of a terminal session to the remote server. PAExec is useful for doing remote installs, checking remote configuration, etc. It is similar to PsExec from Sysinternals.

Enhanced Protection Mode is a new feature within Windows 8. It is enabled by default with the Metro version of Internet Explorer 10, and can be enabled manually with the desktop version.
Enhanced Protection Mode offers some additional features compared to the original Protected Mode introduced with Vista. If the OS version and CPU support is available, all tabs processes are ran as 64-bit. This helps with technologies such as Address Space Layout Randomization. Enhanced Protection Mode restricts IE from locations that contain personal information until permission is granted. Tab processes (which is where untrusted Internet pages load) do not have access to a user’s domain credentials, as well as some other options such as tab processes cannot operate as local webservers.
The desktop version of IE 10 with Windows 8 will use 32-bit tab processes by default if Enhanced Protection Mode is not enabled. Metro IE uses EPM by default, so tab processes will be 64-bit with compatible hardware and operating system.
If a plug-in does not offer support with the desktop version of IE 10 when EPM is enabled, a notification bar should appear near the bottom of the screen.
Below are a few network-based utilities available with Ubuntu. The screen captures below are from Ubuntu version 10.04. The wget command allows HTTP access via a terminal prompt.
The tracepath command is similar to traceroute, but does not require root privileges. The command attempts to trace the “hops” to the destination specified.
The mtr command attempts to combine ping and tracepath. It shows the ping times for each “hop”.
The host command performs DNS lookups.
The dig command can be used for DNS lookups as well.
The whois command displays the whois records for the domain in question.
The ifplugstatus command will display if a network cable is plugged into an interface. It is not installed by default with Ubuntu, but the command sudo apt-get ifplugd should install it. The text “link beat detected” means a connection is present.
The ifconfig command will display information for all network interfaces, including IP addresses and MAC addresses.
The dhclient command will release and renew a DHCP lease. The –r parameter will release the current IP address.
The netstat command will display general information interface statistics. The –p parameter will display the programs associated with open sockets.
The command netstat –na | grep –i listen will display the network listening ports.
