Instructions

  1. Generer et SSH-nøglepar på enhver Linux-server

    [administrator@my-linux-server ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/administrator/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/administrator/.ssh/id_rsa.
Your public key has been saved in /home/administrator/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:FGwVwmaboco...GC86v+4pc administrator@my-linux-server
The key's randomart image is:
+---[RSA 3072]----+
|     . =+o+o     |
|    . + @o.      |
| o + . O.*       |
|* . = +.B        |
|.= + o =So       |
|o . . o . .      |
|o. o ..          |
|+ +..E           |
|   :)            |
+----[SHA256]-----+

    Dette er, hvad du skal se i .ssh-mappen:

    [administrator@my-linux-server .ssh]# ls /home/administrator/.ssh/
id_rsa
id_rsa.pub
known_hosts

  2. Opret en SMB NAS-server, Windows AD-tilsluttet

    F.eks. NAS-server nas-sftp01:
    Fanen SMB-server

    NFS er ikke påkrævet
    Fanen NFS-server

    Indstillinger for SFTP:

    • SFTP aktiveret
    • FTP-/SFTP-serveradgang: SMB-brugere
    • Begrænsning af hjemmemappe: Aktiveret
    Et skærmbillede af en computerDescription genereres automatisk

    "Home Directory Restriction" giver brugeren mulighed for kun at åbne mappen /Home/, men ikke se noget over dette. Fjern markeringen af dette, hvis brugeren skal have adgang til roden af NAS-serveren og filsystemerne.

  3. Opret et filsystem

    Opret et filsystem under NAS-serveren, der er oprettet ovenfor, og opret en SMB-deling.
    Eksempel på filsystemnavn: nas-sftp-fs01.
    Oplysninger om filsystem

  4. Aktivér HomeDir til NAS-server nas-sftp01

    Upload homedir-konfigurationsfilen til NAS-serverens > navngivningstjenester > Lokale filer.

    Bemærk, at du kun sætter filsystemnavnet her nas-sftp-fs01. Brug denne skabelon til vejledning:

     

    Examples:
mydomain:*:/fs2/<d>/<u>:regex:create
mydomain:usr1:/fs1/usr1
!:tom:/fs1/tom
test:*:/nas-sftp-fs01/<d>/<u>:regex:create

  5. Opret en bruger på Windows AD

    Demonstrerer med brugertester som et eksempel.
    Log ind fra en Windows-klient (Windows AD Joined) med brugertesteren , og få adgang til startmappen \\nas-sftp01\HOME for at oprette brugertesterens startmappe.

  6. Gå til den Linux-server, som du oprettede SSH-nøgleparret på, og gå til den placering, hvor nøglen er gemt.

    Du skal omdøbe filen id_rsa.pub til autorized_keys

    [administrator@my-linux-server]$ cd /home/administrator/.ssh/
[administrator@my-linux-server .ssh]$ pwd
/home/administrator/.ssh

[administrator@my-linux-server .ssh]$ ls -la
total 16
drwx------.  2 administrator administrator   57 Mar  4 09:58 .
drwx------. 20 administrator administrator 4096 Jan 23 08:21 ..
-rw-------.  1 administrator administrator 2622 Mar  3 08:19 id_rsa
-rw-r--r--.  1 administrator administrator  582 Mar  3 08:19 id_rsa.pub
-rw-r--r--.  1 administrator administrator  909 Mar  4 08:34 known_hosts

[administrator@my-linux-server .ssh]$ mv id_rsa.pub authorized_keys

  7. Åbn en sftp-forbindelse til NAS-serveren med den nyoprettede bruger

    Opret en .ssh-mappe, og flyt den nye fil authorized_keys til .ssh/-mappen fra placeringen ovenfor (i dette eksempel er dens /home/administrator/.ssh/).

    Erstat xx.xx.xx.xx med NAS-serverens IP eller navn.

     

    [administrator@my-linux-server .ssh]$ sftp test\\tester@xx.xx.xx.xx
test\tester@xx.xx.xx.xx's password:
Connected to xx.xx.xx.xx.

  8. Indstil tilladelse 700 til mappe .ssh og 600 til at arkivere .ssh/authorized_keys ved hjælp af chmod i SFTP

    sftp> ls -la
drwxr-xr-x   3 2147483650 2147483650 2147483650           8192 Mar  4 12:30 .

sftp> cd .ssh/
sftp> ls -la
drwx------   2 2147483650 2147483650 2147483650            152 Mar  4 12:30 .

-rw-------   1 2147483650 2147483650 2147483650            582 Mar  4 12:30 authorized_keys

  9. Test af adgang

    Du bør nu kunne åbne sftp'en uden at angive en adgangskode.
    Du kan bruge indstillingen sftp-v til at vise loginoplysningerne.
