To have access to Outlook’s meeting request and calendar features, you need to install and configure two addons for Thunderbird.
Once the two addons are installed, create a new calendar, select Microsoft Exchange 2007/2010 Use the following settings:
Server URL: https://pod51050.outlook.com/ews/exchange.asmx Primary email address: email@example.com Username: userid@.ads.qub.ac.uk Domain name: [Leave this blank] Share Folder Id: [Leave this blank]
These details are for Queen’s University Belfast, something similar should work with other organizations.
If you are having trouble connecting, check the Server URL. I identified the address by checking the URL bar when I was logged into office365’s outlook web-app. I have been unable to reproduce this, if you find a way to identify which pod you are using please let me know.
With just a fresh install of raspbian, and a network cable, you too can setup your very own Raspberry PI with Internet access.
Make sure you have the same physical setup:
PI (Ethernet) -> (Ethernet) Computer (Wireless or second Ethernet) -> Internet.
Install raspbian onto the SD card. Mount the SD card with write privileges and navigate to the file
/etc/network/interfaces and set a static IP.
auto eth0 iface eth0 inet static address 10.50.50.2 netmask 255.255.255.0 network 10.50.50.0 broadcast 10.50.50.255 gateway 10.50.50.1
On your computer which the PI is connected to configure the ethernet interface. This will allow you to ping and SSH into the PI.
sudo ifconfig p5p1 10.50.50.1 up
Setup the Internet connection sharing on your computer using iptables. You may need to change the interfaces to match yours. Below, wlan0 is my Internet interface, and p5p1 is connected to my PI.
sudo iptables -A FORWARD -o wlan0 -i p5p1 -s 10.50.50.0/24 -m conntrack --ctstate NEW -j ACCEPT sudo iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT sudo iptables -t nat -F POSTROUTING sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
The first rule allows forwarded packets (initial ones). The second rule allows forwarding of established connection packets (and those related to ones that started). The third rule does the NAT.
That’s it, you should now be able to connect to the Internet from your PI. Note that this is a NATed connection, which means that you will not be able to connect to your PI from any machine on the network, with out a bit more work.
Currently OTRv4 (libotr5-dev) is only in testing, which means you need to add the backports repository. (For Ubunutu skip this step, the rest is the same.)
Add the following line to the bottom of
/etc/apt/sources.list if you don’t already have it.
deb http://ftp.debian.org/debian/ wheezy-backports main
Update and install the required libraries to compile mcabber with OTR, PGP and UTF-8 support.
apt-get install build-essential libloudmouth1-dev libgpgme11-dev libncursesw5-dev libotr5-dev
Download and extract the latest release. Currentlythere is no signed, or hashed checksum to confirm.
wget http://mcabber.com/files/mcabber-0.10.3.tar.bz2 tar xvfj mcabber-0.10.3.tar.bz2 cd mcabber-0.10.3
Run the configuration script, you need to specify OTR or it will not compile support for it.
./configure --enable-otr make sudo make install
Confirm everything has compiled and installed correctly.
Create the config directories, along with a place to store your OTR keys.
mkdir -p ~/.mcabber/otr chmod 0700 ~/.mcabber
Create a configuration file, called ~/.mcabber/mcabberrc. Example config file here.
# Basic jabber server stuff set jid = <UserName> set server = <Server> set tls = 1 # Disbale logging. set disable_chatstates = 1 set logging = 0 set load_muc_logs = 0 # Enable OTR to always run. set otr = 1 otrpolicy default always set otr_dir = "~/.mcabber/otr/"
Should all be working, use /help otr to get more information.
/OTR key /OTR start|stop|info [jid] /OTR fingerprint [jid [fpr]] /OTR smpq|smpr [jid] secret /OTR smpa [jid] You can use the shortcut-jid "." for the currently selected contact. /otr key Print the fingerprint of your private key to the Status Buffer /otr start [jid] Open an OTR channel to the specified jid (or the currently selected contact) /otr stop [jid] Close the OTR channel to the specified jid (or the currently selected contact) /otr info [jid] Show current OTR status for the specified jid (or the currently selected contact) /otr fingerprint [jid [fpr]] Show the active fingerprint of an OTR channel. If the fingerprint is provided instead of "fpr", the fingerprint will become trusted. If you replace "fpr" by some bogus string the fingerprint will loose the trusted status. /otr smpq [jid] secret Initiate the Socialist Millionaires Protocol with the secret and the buddy /otr smpr [jid] secret Respond to the Initiation of the jid with the secret /otr smpa [jid] Abort the running Socialist Millionaires Protocol
If you’re using a window manager, such as awesome or goomwwm, instead of a desktop environment, such as GNOME or XFCE, then you might have the issue of some GTK applications not looking quite right, a problem I had was with missing icons.
Before and after:
List all available icons themes:
ls ~/.icons/ /usr/share/icons/
You need to append the line,
gtk-icon-theme-name = "-insert-theme-name-", to
echo "gtk-icon-theme-name = \"Humanity\"" >> /etc/gtk-2.0/gtkrc
The above command globally sets the theme to Humanity. The command is appended if the file exists, and creates it if not.
Reconfigure wirehsark-common so that it allows non-root users to access the interface. Add the user to the wireshark group.
dpkg-reconfigure wireshark-common usermod -a -G wireshark <user>
To force flash to not exit full screen when focus is lost, edit the NET_ACTIVE_WINDOW, in libflashplayer.so
sudo sed -i 's/_NET_ACTIVE_WINDOW/__ET_ACTIVE_WINDOW/g' /usr/lib/firefox-addons/plugins/libflashplayer.so
XBindKeys uses a configuration file, located at $HOME/.xbindkeysrc.
Contents of my .xbindkeysrc
"gnome-terminal" Mod2 + F12
You can create your own config, or have a default one generated for you.
xbindkeys --defaults > $HOME/.xbindkeysrc
To get the correct key codes, you can use -k to identify key presses. It will open a blank window and output the command to be placed into your configuration file.
XBindKeys should be easily found in your package manager.
ULOG is the netfilter/iptables logging daemon. It connects to the netlink device of the Linux kernel and reads messages from the netfilter that get queued with the iptables ULOG target. It can output to plain text, MySQL, Postgres and PCAP.
apt-get install ulogd-pcap
Configure ulogd to output in PCAP format
plugin="/usr/lib/ulogd/ulogd_PCAP.so", restart ulog. Then add a log rule to iptables before the final drop rule.
-A INPUT -j ULOG
The PCAP log file should be located at
Installing a LaTeX class in three simple steps.
Copy your .cls file to the same directory.
sudo cp yourclsfile.cls /usr/share/rest/of/the/path/from/above
Update the kpathsea database.
There are times when you want to change your MAC address, be it for fun, by-passing time restrictions or for development reasons.
For Linux there is a nice small tool which does this for you. It’s called macchanger. You can download and compile it or install it with your package manager.
For example, on Debian/Ubuntu you can do:
sudo apt-get install macchanger
Make sure you are not connected to the network first, and bring down your interface. In this case it’s my wireless interface, you may want to use your ethernet, which might be eth0.
sudo ifconfig wlan0 down
Now we change the end of the MAC address which will change your address but keep the same vendor bytes. For more information about this read up on MAC addresses
sudo macchanger -e wlan0
Now bring the interface back up, and connect to the network using your network manager.
sudo ifconfig wlan0 up
Check if we still have the new address.
You should see something like this, if your current address is different then all is good.
Permanent MAC: 00:2F:77:36:57:F4 (Intel Corporate) Current MAC: 00:2F:77:F4:CE:02 (Intel Corporate
