Configuration

Using Netkit for setting up and performing networking experiments.

---

• Netkit version 2.8
• Fedora version 28

STEP 1: DOWNLOAD AND UNPACK

Download all the files of the official site to a directory of your choice. Then unpack them by using the following commands:

• tar -xjSf netkit-x.y.tar.bz2
• tar -xjSf netkit-filesystem-Fx.y.tar.bz2
• tar -xjSf netkit-kernel-Kx.y.tar.bz2

STEP 1.1: SPECIFIC DOWNLOADS FOR FEDORA USERS

after unpack the files run into your terminal the following commands:

• sudo dnf install audit.x86_64 glibc.i686 glibc.x86_64
• sudo dnf install xterm

Note that all the three packages must be uncompressed while staying in the same directory.

STEP 2: CONFIGURATION

The first step is to set the environment variable NETKIT_HOME to the name of the directory Netkit has been installed into. In order to access the Netkit man pages, the MANPATH variable must be set to ":$NETKIT_HOME/man". For example, assuming that you have installed Netkit to /home/foo/netkit and that your shell is bash, you would use the following commands:

• export NETKIT_HOME=/home/foo/netkit
• export MANPATH=:$NETKIT_HOME/man

It may also be useful to put these lines inside your shell initialization file (.bashrc in case you are using the bash shell).

After doing this, you need to update your PATH environment variable to include the path to the standard Netkit commands. This is required in order to make Netkit work properly. The entry you need to add to the PATH is "$NETKIT_HOME/bin". For example, assuming Netkit is (still) installed into /home/foo/netkit and that your shell is (still) bash, you would type:

• export PATH=$NETKIT_HOME/bin:$PATH

Again, it may be convenient to put this line inside your shell initialization file.

STEP 3: CHECK YOUR CONFIGURATION

At this point, change the current directory to the Netkit directory:

• cd netkit

Now, run the check_configuration.sh script by typing:

• ./check_configuration.sh

This script takes care of checking whether your system is configured properly to make Netkit run. Any misconfigurations are signalled and instructions for fixing them are reported as well. If the script exits with success, then Netkit is ready for use.

Basically all these steps are from the official site, except about the STEP 1.1, that is specific for fedora users.
