1. Use the ssh command to log in to serverb as the student user.

   [student@workstation ~]$ ssh student@serverb
   ...output omitted...
   [student@serverb ~]$ 

2. Use the su command to switch to the root user because creating the /configsync directory requires superuser privileges. In later steps, you will archive the files present in the /etc directory tree, which are owned by the root user this also requires superuser privileges.

   [student@serverb ~]$ su -
   Password: redhat
   [root@serverb ~]# 

3. Create the /configsync directory to store the synchronized configuration files from servera.

   [root@serverb ~]# mkdir /configsync

4. Use the rsync command to synchronize the /etc directory tree from servera to the /configsync directory on serverb.

   Be aware that only the root user can read all the content in the /etc directory on servera.

   [root@serverb ~]# rsync -av root@servera:/etc /configsync
   root@servera's password: redhat
   receiving incremental file list
   etc/
   etc/.pwd.lock

1. Use the tar command with the -czf options to create a gzip compressed archive.

   [root@serverb ~]# tar -czf configfile-backup-servera.tar.gz /configsync
   tar: Removing leading `/' from member names
   [root@serverb ~]# 

2. Use the tar command with the -tzf options to list the contents of the configfile-backup-servera.tar.gz archive.

   [root@serverb ~]# tar -tzf configfile-backup-servera.tar.gz
   ...output omitted...
   configsync/etc/vimrc
   configsync/etc/wgetrc
   configsync/etc/xattr.conf

[root@serverb ~]# scp ~/configfile-backup-servera.tar.gz \
student@workstation:/home/student
...output omitted...
student@workstation's password: student
configfile-backup-servera.tar.gz            100% 5110KB  64.5MB/s   00:00

1. Exit from serverb.

   [root@serverb ~]# exit
   logout
   [student@serverb ~]$ exit
   logout
   Connection to serverb closed.
   [student@workstation]$ 

2. Create the /tmp/savedconfig directory, where the contents of the /home/student/configfile-backup-servera.tar.gz archive will be extracted.

   [student@workstation ~]$ mkdir /tmp/savedconfig

3. Change to the /tmp/savedconfig directory.

   [student@workstation ~]$ cd /tmp/savedconfig
   [student@workstation savedconfig]$ 

4. Use the tar command with the -tzf options to list the contents of the configfile-backup-servera.tar.gz archive

   [student@workstation savedconfig]$ tar -tzf ~/configfile-backup-servera.tar.gz
   ...output omitted...
   configsync/etc/vimrc
   configsync/etc/wgetrc
   configsync/etc/xattr.conf

5. Use the tar command with the -xzf options to extract the contents of the /home/student/configfile-backup-servera.tar.gz archive to the /tmp/savedconfig/ directory.

   [student@workstation savedconfig]$ tar -xzf ~/configfile-backup-servera.tar.gz
   [student@workstation savedconfig]$ 

6. List the directory tree to verify that the directory contains files from the /etc directory.

   [student@workstation savedconfig]$ ls -lR
   .:
   total 0
   drwxr-xr-x. 3 student student 17 Feb 13 10:13 configsync
   
   ./configsync:
