Use the ssh command to log in to servera as the student user.

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

Create a directory named /home/student/serverlogs on servera. Use the rsync command to securely create an initial copy of the /var/log directory tree on serverb in the /home/student/serverlogs directory on servera.

1. On servera, create the target directory named /home/student/serverlogs to store the log files synchronized from serverb.

   [student@servera ~]$ mkdir ~/serverlogs

2. Use the rsync command to synchronize the /var/log directory tree on serverb to the /home/student/serverlogs directory on servera. Note that only the root user can read all the content in the /var/log directory on serverb. All files are transferred in the initial synchronization.

   [student@servera ~]$ rsync -av root@serverb:/var/log ~/serverlogs
   root@serverb's password: redhat
   receiving incremental file list
   log/
   log/README
   log/boot.log

As root on serverb, execute the logger "Log files synchronized" command to get a new entry in the /var/log/messages log file to reflect when the last synchronization took place.

[student@servera ~]$ ssh root@serverb 'logger "Log files synchronized"'
Password: redhat
[student@servera ~]$ 

Use the rsync command to securely synchronize from the /var/log directory tree on serverb to the /home/student/serverlogs directory on servera. Note that this time only log files that have changed are transferred.

[student@servera ~]$ rsync -av root@serverb:/var/log ~/serverlogs
root@serverb's password: redhat
