Lab 4: Operating System Identification
Detect Operating System of Target: Xprobe2
Prerequisites:
None
Countermeasures:
IDS to detect UDP to port 32132, deny ICMP
requests/reply.
Description:
The Xprobe2 application is used to identify the possible
operating system (OS) of the target. An attacker uses this information
to launch appropriate attacks for the results obtained. Remember that
all commands in Linux are
case sensitive
.
Procedure:
Uncompress, compile, create the Xprobe2 executable and
execute against the target with the syntax of:
Xprobe2 options Target IP ADDRESS
From the Linux directory containing the type Xprobe compressed file, type
tar ??“zxvf xprobe2-0.3.tar.gz
.
The Xprobe files will uncompress and install into a new directory named
xprobe2-0.3
.
Change to the new directory by typing
cd xprobe2-0.3
and pressing
Enter
.
The Xprobe application needs to be configured for the machine it is
currently running on by typing i
./configure
.
The files will configure for the machine they are currently on. Be patient
as this may take a few minutes depending on the computer.
The next step is to type
make
and press
Enter
.

The make command will execute.
The last step prior to execution is to install the Xprobe application by typing:
make install
