From workstation, run the lab archive-transfer start command. The command runs a start script that determines whether hosts servera and serverb are reachable on the network. The script also ensures that the file and directory to be created in the exercise does not exist on servera.

[student@workstation ~]$ lab archive-transfer start

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

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

Use the scp command to copy the /etc/ssh directory from serverb to the /home/student/serverbackup directory on servera.

On servera, create a directory named /home/student/serverbackup.
```
[student@servera ~]$ mkdir ~/serverbackup
```

Use the scp command to recursively copy the /etc/ssh directory from serverb to the /home/student/serverbackup directory on servera. When prompted, enter redhat as the password. Note that only the root user can read all the content in the /etc/ssh directory.

[student@servera ~]$ scp -r root@serverb:/etc/ssh ~/serverbackup

Exit from servera.

[student@servera ~]$ exit
logout
Connection to servera closed.
[student@workstation]$

Finish

On workstation, run the lab archive-transfer finish script to complete this exercise.

[student@workstation ~]$ lab archive-transfer finish

16 sty 2024

Hello,I am trying to finish up Lab 3 of the Chapter 15 Comprehensive Review Labs in RH124, and when I type in sudo dnf install zsh for the 6th specification of the lab, I get an error message basically saying that it failed to download metadata for the repo 'ansible-2.9-for-rhel-9-x86_64-rpms', and that they could not download repomd.xml. It provided a 404 status code.Can someone please let me know what the problem is, and if there is a current workaround? Thanks.
