Creating a Chrooted Environment

This lab will allow you to practice creating a chrooted environment, adding access to Linux commands, along with including shared libraries for these commands.

You will create a chrooted jailed environment as well as ensuring the inmates can `cat` out the false escape plans that you will leave behind.

mkdir /home/elba/{bin,lib64}
```

Copy /bin/bash into /home/elba/bin/bash.

Copy /bin/bash into /home/elba/bin/bash.
```
cp /bin/bash /home/elba/bin/bash
```

Copy /bin/ls in to /home/elba/bin/ls

Copy /usr/bin/ls into /home/elba/bin/ls.
```
cp /bin/ls /home/elba/bin/ls
```

Copy /bin/cat in to /home/elba/bin/cat

Copy /bin/cat into /home/elba/bin/cat.
```
cp /bin/cat /home/elba/bin/cat
```

Copy the libraries needed for bash, ls, and cat over to /home/elba/lib64.

Find and copy the libraries needed for bash, ls, and cat over to /home/elba/lib64.

ldd /bin/bash /bin/ls /bin/cat

cp /lib64/libtinfo.so.5  
/lib64/libdl.so.2 
/lib64/ld-linux-x86-64.so.2 
/lib64/libselinux.so.1 
/lib64/librt.so.1 
/lib64/libcap.so.2 
/lib64/libacl.so.1 
/lib64/libc.so.6 
/lib64/libpthread.so.0 
/lib64/libattr.so.1 
/lib64/libpcre.so.1  /home/elba/lib64

Create the waterloo.txt file in the /home/elba directory

Using vi, create the waterloo.txt file in the /home/elba directory with instructions on how to escape.
```
vi /home/elba/waterloo.txt
```

Create a chrooted environment in /home/elba with a bash shell.

Using the chroot command, create a chrooted environment in /home/elba with a Bash shell.
```
chroot /home/elba /bin/bash
```

Confirm commands work.

Using the command pwd, confirm the present working directory and then confirm that you can use the ls command.
```
pwd
```
```
ls
```
```
cat
```

View the contents of waterloo.txt and find out how to escape your environment.

View the contents of waterloo.txt and find out how to escape your environment.
