Ciao a tutti,

se avete bisogno di creare un'immagine su disco di un dvd o cd questa procedura semplice e veloce.

A cd non montato potete usare il comando:

dd if=/dev/dvd of=dvd.iso # se é un dvd
dd if=/dev/cdrom of=cd.iso # se é un cdrom
dd if=/dev/scd0 of=cd.iso # se é un lettore scsi

Per creare invece una iso da file su disco il comando é il seguente:

mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom

mkisofs -r -o immagine.iso /media/cdrom0

Alla prossima :)

This was written using OpenSSL 0.9.5 as a reference.

To start with, you'll need OpenSSL. Compilation and installation follow the usual methods. It's worth while to note that the default installs everything in /usr/local/ssl. No need to change this (unless you want to).

After you have this installed, you may want to edit the OpenSSL configuration file with the information for your site so you have pleasant defaults when creating and signing certificates. You'll find this in /usr/local/ssl/openssl.cnf in the section req_distinguished_name Here you can set the defaults (denoted by the _default appended to the variable name). Any settings that do not have a default, such as localityName can have one set by appending _default. In this case you'd set localityName_default.

Now, we move on to creating a private Certificate Authority (CA). First, some explanation. The CA is used in SSL to verify the authenticity of a given certificate. The CA acts as a trusted third party who has authenticated the user of the signed certificate as being who they say. The certificate is signed by the CA, and if the client trusts the CA, it will trust your certificate. For use within your organization, a private CA will probably serve your needs. However, if you intend use your certificates for a public service, you should probably obtain a certificate from a known CA.

In addition to identification, your certificate is also used for encryption. If you're thinking a certificate sounds similar to a PGP key, you're right. They use many of the same methods. Something else PGP and SSL have in common is the RSA encryption algorithm, which is patented. This patent expires in September of 2000, so after that you'll be free to use tools with the RSA algorithm (like OpenSSL). Until that time, to legally use RSA you need a license. RSA Data Security usually allows non-commercial use of the RSA algorithm for academic purposes.

Creating a private CA

• Go to the OpenSSL bin directory (/usr/local/ssl/misc by default).
• There should be a script called CA.sh (and a CA.pl that does the same stuff). This hides all the gruesome details of how this works. Without the script this is a very annoying process.
• su to root
  • Make sure that the OpenSSL bin directory is in your path.
• ./CA.sh -newca
  • When prompted for CA filename hit return.
  • Answer the rest of the questions intelligently. The common name would be how this certificate might be referred to. For example, the Equifax Secure CA uses the common name of Equifax Secure Certificate Authority.

Creating certificates

• ./CA.sh -newreq
  • This creates an unsigned certificate request.
  • The procedure is the same as creating a private CA except you'll want to use the name of the host that will use the certificate as the common name (host.domain.com). If they don't match, the client will not like it.
  • You probably don't want to use the same passphrase for this as you did with the CA.
• ./CA.sh -sign
  • It will ask for a PEM pass phrase, that's the passphrase you set for the private CA you created.
  • This signs the certificate that you just created with the CA you created just moments before. You can generate multiple certificates. You'll probably need to. For example, mail.foo.com and www.foo.com each need their own certificate.
• The signed certificate is now in the current directory as newcert.pem. If you are going to create more, you should rename this or it will be overwritten be subsequent signatures.

Creating client-side certificates

• openssl pkcs12 -export -in certs.pem -inkey certs.key -out file.p12 -name "Client Certificate"

Ciao a tutti,

vi é mai capitato di aver installato tante di quelle cose che non sapete più come liberare il telefono?Oppure il telefono fa le bizze e non capite il perchè?

La soluzione in molti casi é un bel deep reset!

Il deep reset può essere fatto in questi tre modi a seconda del vostro smartphone:

- *#7370#
- *#7780#
- accendi il cel pigiando contemporaneamente *+tasto verde+3 e il tasto di accensione fino alla schermata delle mani nokia
 

Spero di esser stato d'aiuto.

A presto

Allora partiamo dal kernel.Se avete una versione di kernel inforiore alla 2.6.5 (esclusa) avete bisogno di patcharlo con delle patch disponibili su www.prism54.org

(ricordatevi di abilitare i supporti pcmcia anche nella sezione periferiche altrimenti la vostra scheda potrebbe non essere vista). Io sul mio notebook uso Slackware con kernel 2.6.4 patchato.Fatto questo avete bisogno del pacchetto madwifi che trovate a questo link

http://prdownloads.sourceforge.net/madwifi/madwifi-20030802.tgz?download

Il pacchetto è un .tgz che su slackware potete installare con il comando "installpgk madwifi-20030802.tgz". A questo punto vi occorre uno script di configurazione,

ecco il mio basta che copiate e incollate su un file e gli date i permessi di esecuzione (chmod +x nomefile):

--------------------------------------------------

#!/bin/sh

#

iwpriv ath0 mode 3

iwconfig ath0 essid "any"

iwconfig ath0 mode Managed

iwconfig ath0 nickname "nomepc"

iwconfig ath0 key restricted CHIAVEWEP

ifconfig ath0 up ifconfig ath0 192.168.0.IP

route add default gw INDIRIZZO.IP.DEL.ROUTER

--------------------------------------------------

Lanciate questo script (oppurtunamente modificato per la vostra rete) e sarete connessi.

P.S.=Ancora i driver madwifi non consentono la connessione AdHoc (tra 2 schede wifi) ma solo agli access point.

Per prima cosa scaricare i sorgenti (che si trovano su emule o simili) per linux (vnc-3.3.7-x86_linux.tar.gz) e per windows (realvnc,tighvnc etc...).

A questo punto,pensando che la macchina linux sia senza monitor e che faccia da server, passiamo all'installazione:

una volta che il tuo sistema è installato e configurato copia il pacchetto in /usr/src e scompattalo,verrà creata una cartella.

Entra nella cartella e compila e installa( ./configure && make && make install ), ora non resta che lanciare il vncsever.

Consiglio di scegliere un window manager leggero (io ad es. uso windowmaker , lo potete cambiare con il comando xwmconfig)!!

Ok siamo pronti!Spegnete e togliete lo schermo alla macchina linux poi riaccendetela senza monitor (ricordatevi di disabilitare nel bios l''opzione sul controllo della tastiera al boot altrimenti il vostro pc non si avvierà).

Ok,entriamo dalla macchina windows con ssh sulla macchina linux (c'è un programma che si chiama PUTTY che fa al caso nostro) e,non da utente root,lanciamo "startx".

Ora apriamo un'altra connessione ssh verso la stessa macchina linux con il solito user (importante altrimenti vnc non funzionerà!!) e lanciate il seguente comando:

vncserver :1 -geometry 1024x768 -name nomeserver

il programma vi chiederà di impostare una password per l'accesso da remoto.

Ci siamo!

Aprite realvnc viewer e alla richiesta dell'host inserite iphost:1 , vi si aprirà una richesta password mettete la password che avete inserito sul vnc del server (macchina linux).

Adesso dovreste vedere il desktop della vostra macchina senza schermo.
