Debian, Ubuntu et al.

Tried to upgrade to Ubuntu 15.10 Beta 2, rebooted  and my system was broken. Could not connect to LAN, so my only option was to connect to Wifi via command line to hopefully repair my system. This is what I did. First, open a terminal: Ctrl-Alt-T If you got WPA like me you need wpa_supplicant to set it up, because iw can only handle WEP. To bring up your wireless device (most likely wlan0): sudo -s ifconfig wlan0 up #now scan for available wifi networks and note the ssid of your device iwlist wlan0 scan In /etc/wpa_supplicant.conf we need to put our ssid and password: nano /etc/wpa_supplicant.conf Example config: network={                      ssid="ssid"                      psk="wifi password" } Ctrl + A to close and save. To connect: sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext Open a second tab/terminal: sudo dhclient wlan0 Your connection should now work!

OS: Ubuntu 15.04 There is also a GPU version (oclhashcat), but I am on my notebook so I have to use the CPU only version, which - of course - is much slower. Download the latest hashcat version here: https://hashcat.net/hashcat/ Download a wordlist: https://crackstation.net/buy-crackstation-wordlist-password-cracking-dictionary.htm Create a MD5 hash: E.g.: 'hello' echo -n "hello" | md5sum 5d41402abc4b2a76b9719d911017c592 Next, extract the hashcat archive and create a .txt file with the md5 hash(es) within the folder. Also, save the wordlist in the hashcat folder. Start hashcat. Dictionary based attack. Command: ./hashcat-cli64.bin -n 2 -m 0 -a 8  test.txt realhuman_phill.txt -n,   --threads=NUM                 Number of threads -m,  --hash-type=NUM              Hash-type -a,  --attack-mode=NUM          Attack-mode --> use ./hashcat-cli64.bin -h to display all available options. test.txt is the file with the md5 hash(es) and realhuma

Open a terminal and enter: sudo apt-add-repository ppa:i2p-maintainers/i2p Update your repositories and install i2p: sudo apt-get update sudo apt-get install i2p Start the I2P router ( never as root ): i2prouter start Configure your browser to connect through I2P. I'd recommend you to use Firefox. Preferences --> Advanced --> Network tab. In the Connections section, click on the Settings button. Click the circle next to Manual proxy configuration, enter 127.0.0.1 , port 4444 in the HTTP Proxy field. Enter 127.0.0.1 , port 4445 in the SSL Proxy field. Add localhost and 127.0.0.1 into the "No Proxy for" box.
