Per abilitare e configurare FTP da Unisphere (interfaccia utente):

service@spa spa:~> uemcli -no -u admin -p mypasswd /net/nas/ftp -server nas_8 set -ftpEnabled yes -sftpEnabled yes -anonymousUserEnabled yes -cifsUserEnabled yes -unixUserEnabled yes
Operation completed successfully.



Note : Refer to "uemcli /net/nas/ftp -help" for all other available options

 



Per accedere come utente FTP:

Se il server NAS dispone di un dominio aggiunto Server CIFS (Common Internet File System), l'utente di dominio può effettuare l'accesso con uno dei seguenti elementi:

domain\user or user@domain

Example (domain name is EXAMPLE):
EXAMPLE\user100 or user100@example.com


Se il server NAS è un server CIFS standalone su Unity, il metodo seguente consente l'accesso:

servername\user or user@servername or local\user or user@local

Example (standalone nas server name is MYCIFS):

MYCIFS\user100 or user100@mycifs or local\user100 or user100@local

C:\>ftp ftp02

220 NASFTP FTP server (EMC:upc_Unity_6_HF5_upcBuilder:9328432) ready.

331 Password required for Local\administrator.
Password:
230- No directory! Logging in with home=/nasftp_fs01.
230 NT User Local\administrator logged in.

Se il server NAS viene utilizzato per Solo NFS (Network File System), Unity richiede un servizio directory (come LDAP (Lightweight Directory Access Protocol) o NIS (Network Information Service)) per l'autenticazione utente. I file locali possono essere utilizzati anche se non sono disponibili LDAP o NIS (che richiedono la configurazione manuale di utente/password).

Accesso anonimo (chiamato anche ftp):

C:\>ftp ftp02
Connected to ftp02
220 FTP02 FTP server (EMC:upc_Unity_6_HF5_upcBuilder:9328432) ready.
User (ftp02  :(none)): anonymous
331 Guest login ok, type your name as password.
Password:
230 Guest login ok, access restrictions apply.
ftp> _



Per configurare gli utenti locali:

I dettagli dell'utente devono essere immessi in questo modo:

01:42:18 service@spa spa:~> cat passwd
# The passwd file contains the users who can access the NAS server.
#
# Each line of the passwd file defines a user and has the format:
#   username:password:uid:gid:gcos
# where:
# - username is the user's login name.
#   When querying for Windows users, the system checks for CIFS usernames without domain extensions.
# - password is an empty field. The encrypted password for the user is in the
# corresponding entry in the shadow file.
# - uid is the user's unique numerical ID for the system.
# - gid is the unique numerical ID of the group to which the user belongs.
#
# user:password:uid:gid:gcos:homedir:
ftp:ffX6M7x34lzYI:2000:2000::/fs01:
user100:ffX6M7x34lzYI:2001:2001::/fs01:

Utilizzare UEMCLI per scaricare:

uemcli -u admin -p password -download /net/nas/server -name server_name -type passwd


EXAMPLE:
03:37:51 service@spa spa:~> uemcli -u admin -p mypasswd -upload -f /home/service/passwd /net/nas/server -name FTP02 -type passwd

Uploaded 962 byte of 962 byte [ 100.0% ] -PROCESSING-
Operation completed successfully.




Usa UEMCLI per caricare:

uemcli -u admin -p password -upload -f /cores/service/passwd /net/nas/server -name server_name -type passwd


EXAMPLE:
03:37:40 service@spa spa:~> uemcli -download -f /cores/service/passwd /net/nas/server -name FTP02 -type passwd

Downloaded 962 byte of 962 byte [ 100.0% ] -STALLED-
Operation completed successfully.

Additional Information

Note:

  • Affinché l'utente anonimo funzioni, deve essere presente un utente denominato ftp a UID deve essere definito nel provider di directory o nei file locali.
    • Esempio per i file locali: ftp:*:1000:1000::/fs01/publicftp:
  • Se si utilizza Local Files, il campo password può essere generato utilizzando openssl (direttamente da Unity):
    • Esempio: User user100, Password to be "Password123#", uid and gid as 3000, homedir as /fshomedir/data
    • Questo comando utilizza l'algoritmo della password basato su SHA256. utilizzare il comando 'openssl passwd -6 Password123#' se è necessario l'algoritmo della password basato su SHA512.
$ openssl passwd Password123#
Warning: truncating password to 8 characters              <-- note, it takes only 1st 8 char
9QWNQEDjvlRog
$ openssl passwd
Password:                     <-- password can be typed here if not to be seen
Verifying - Password:
yT4C/OPx6AHXM
    Entry on "passwd" file should be: user100:9QWNQEDjvlRog:3000:3000::/fshomedir/data:
  • SFTP richiede che la directory principale sia di proprietà dell'utente che ha effettuato l'accesso.
    • In questo modo è possibile bloccare un utente anonimo.
  • SFTP potrebbe non riuscire se LACP viene utilizzato.
