# portsnap fetch update

Install webmin from /usr/ports/sysutils/webmin, enter:

# cd /usr/ports/sysutils/webmin
# make install clean

Configure webmin

Now, webmin is installed. Start webmin on startup, enter:

# vi /etc/rc.conf

Append following line:

webmin_enable="YES"

Save and close the file. You need to run /usr/local/lib/webmin/setup.sh script in order to setup the various config files, enter:

# /usr/local/lib/webmin/setup.sh

Sample output:

to the administration programs. The setup script needs to know :
 - What port to run the web server on. There must not be another
   web server already using this port.
 - The login name required to access the web server.
 - The password required to access the web server.
 - If the webserver should use SSL (if your system supports it).
 - Whether to start webmin at boot time.

OS X Ripristino password Admin

By Zilli,

Avvia il Mac in modalità utente singolo tenendo premuti i tasti Command+S (o Mela+S che dir si voglia) finché non compaiono delle scritte sul terminale, digita:

$ fsck -fy 
$ mount -uw /
$ launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist
$ dscl . -passwd /Users/username password

nomeutente è il vero nome utente (quello che sarebbe riportato vicino alla “casetta” per intenderci) e password la nuova password che vuoi impostare.
Se non conosci il nome utente di un account amministratore ti basterà digitare more /etc/passwd per visualizzare il file dove sono memorizzati tutti gli utenti presenti nel sistema. Noterai il tipo di privilegio dell’utente nella quinta colonna. Potresti inoltre cambiare direttamente la password dell’utente root (che sui sistemi Unix rappresenta il superuser del sistema e quindi con accesso totale).
Riavvia infine il sistema tenendo premuto il pulsante di accensione
