Arethusa le test

08/05/2021 Aucun commentaire

Un nouveau test VPN publié par le blog du VPN. Ici les VPN sont testés , configurés par créer une base de données la plus fiable possible. Arethusa à ses adeptes, il a déjà été l’ objet d’ une publication par alipaxe. Comme toujours on essayera d’ insister sur les particularités: méthode de configuration – protocole rare – tutos techniques.

Arethusa est proposé par S6N.org: une organisation internationale à but non lucratif fondée en 2003, pour promouvoir liberté d’expression sur Internet. La juridiction dont dépend ce VPN est celle des îles Seychelles: « Applicable jurisdiction for the handling of personal data is the Republic of Seychelles. Only Seychelles authorities can ask us to reveal your personal details. The only details we have about you are the ones you entered yourself. » Le whois de S6N.org confirme l’ enregistrement de nom de domaine de  l’ organisation à Victoria, capitale de cette République. Bien que le site soit en Anglais, le support technique et l’ interface sont en français. Lire la suite…

Configurer une Freebox pour autoriser une connexion VPN à un routeur DD-WRT

freebox-revolutionLa question revient assez souvent pour se connecter à distance chez soi au travers un VPN quand on dispose d’un routeur sous DD-Wrt derrière une box ADSL.
Dans le cas que vais expliquer ci-dessous, je prendrai le cas d’une Freebox V4 et d’une Freebox V6.

Il faut tout d’abord savoir que DD-Wrt embarque un très bon parefeu et que nos box ADSL françaises sont aussi équipées d’un parefeu quand elles sont en mode routeur et non pas en mode passerelle (gateway ou bridge). Lire la suite…

Using ssh as a SOCKS proxy on Mac OS X

18/04/2021 Comments off

Introduction

Many times it can be convenient to tunnel your web traffic through a proxy, particularly an encrypted one. This web page shows how to easily tunnel your traffic through an ssh-encrypted proxy on Mac OS X. This allows your traffic to traverse your local network without being visible to snoopers, even when visiting unencrypted sites.

It also allows you to appear to come from a different IP address, allowing you to defeat geolocation schemes. In particular, some credit card processors try to make sure that your credit card billing address is correlated with your IP address, which can be hard on us expatriates. Another example is the free credit report web site which doesn’t seem to work from outside the United States. There are undoubtedly many other practical, legitimate uses for this sort of redirection.

How to find out Router MAC address

21/03/2021 Comments off

Source: nixCraft

MAC is acronym for for Media Access Control address. It is a unique identifier attached to almost most all networking equipment such as Routers, Ethernet cards and other devices.

If you do not have access to router admin interface (via telnet or webbased), use following method to find out router MAC address.

You need to use arp command (available on both Windows, Linux/Unixish systems).

arp manipulates the kernel’s ARP cache in various ways. The primary options are clearing an address mapping entry and manually setting up one. For debugging purposes, the arp program also allows a complete dump of the ARP cache.

arp shows the entries of the specified hosts. If the hostname parameter is not used, all entries will be displayed.

Task: Find out router Mac Address

To find out your router MAC address, use arp command as follows:

$ /usr/sbin/arp -a
OR
$ arp -a
Output:

router (192.168.1.254) at 00:08:5C:00:00:01 [ether] on eth0
fbsd6 (192.168.1.16) at 00:0F:EA:91:04:07 [ether] on eth0

In above example 00:08:5C:00:00:01 is MAC address of my router. If you cannot find MAC address then just ping to your router once (my router had 192.168.1.254 IP)
$ ping 192.168.1.254
And then run (type arp -a) above arp command again. If you have telnet access to router then you can just telnet into router and find out MAC address:
$ telnet 192.168.1.254

Output:

Welcome to nixCraft Router!
Login: admin
Password:

Once logged in type ifconfig command:

$ ifconfig br0

Output:

br0             Link encap:Ethernet  HWaddr 00:08:5C:00:00:01
        inet addr:192.168.1.254  Bcast:192.168.1.255  Mask:255.255.255.0
        UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
        RX packets:48574 errors:0 dropped:0 overruns:0 frame:0
        TX packets:61329 errors:0 dropped:0 overruns:0 carrier:0
        collisions:0 txqueuelen:0
        RX bytes:9146189 (8.7 MiB)  TX bytes:74456679 (71.0 MiB)

Please note that your interface name (br0) could be different. You can also use ifconfig -a command.

Windows XP/NT/2003 find out Router Mac address

If you are using Microsoft Windows XP then you need to open MS-DOS shell prompt first. Click on Start > Run > Type cmd command followed by ENTER key. Then at C:\> prompt, type arp command as follows:

C:\> arp -a
