Use the ssh command to log in to servera as the student user. The systems are configured to use SSH keys for authentication, and therefore a password is not required.

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

Create a hard link named /home/student/backups/source.backup for the existing file, /home/student/files/source.file.

1. View the link count for the file, /home/student/files/source.file.

   [student@servera ~]$ ls -l files/source.file
   total 4
   -rw-r--r--. 1 student student 11 Mar  5 21:19 source.file
   

2. Create a hard link named /home/student/backups/source.backup. Link it to the file, /home/student/files/source.file.

   [student@servera ~]$ ln /home/student/files/source.file \
   /home/student/backups/source.backup
   

3. Verify the link count for the original /home/student/files/source.file and the new linked file, /home/student/backups/source.backup. The link count should be 2 for both files.

   [student@servera ~]$ ls -l /home/student/files/
   -rw-r--r--. 2 student student 11 Mar  5 21:19 source.file
   [student@servera ~]$ ls -l /home/student/backups/
   -rw-r--r--. 2 student student 11 Mar  5 21:19 source.backup
   

Create a soft link named /home/student/tempdir that points to the /tmp directory on servera.

1. Create a soft link named /home/student/tempdir and link it to /tmp.

   [student@servera ~]$ ln -s /tmp /home/student/tempdir

2. Use the ls -l command to verify the newly created soft link.

   [student@servera ~]$ ls -l /home/student/tempdir
   lrwxrwxrwx. 1 student student  4 Mar  5 22:04 /home/student/tempdir -> /tmp
   

Exit from servera.
