If you get this error trying to ping addresses:
ping: icmp open socket: Operation not permitted
Per this post, chmod ping like this and then it will work as expected.
sudo chmod u+s /bin/ping
Configuring a static IP for Raspbian/Debian Jessie
Looks like on Raspbian Jessie the way you configure a static IP has changed. You used to configure static IPs in /etc/network/interfaces, but on Jessie it looks like the file to edit is now /etc/dhcpcd.conf (per the comment at the top of the prior file).
Scroll to the end of the file and paste something like this, editing IPs to match your network:
interface eth0 static ip_address=192.168.1.xxx/24 static routers=192.168.1.xxx static domain_name_servers=8.8.8.8, 8.8.4.4
Reboot, done.
Building autogen based source on Ubuntu and derivatives
Install build tools:
sudo apt-get install build-essential
Install autogen tools:
sudo apt-get install autogen
In project source:
./autogen.sh
If you get errors like this:
configure.ac:25: error: possibly undefined macro: AC_PROG_LIBTOOL
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
… then also install libtool
sudo apt-get install libtool
Then build and install as normal:
./configure
make
sudo make install
How to reset your password on Raspbian
What not to do: reset your password before you change/setup your keyboard locale, use punctuation characters in your new password, and then change the locale. Yeah, that’s not going to work. Now I don’t know where some of the characters moved to 🙂
I’m going to leave this post right here for future reference.
Update 2/3/16: after I edit the cmdline.txt and booted to a shell, passwd gave me this error:
passwd: Authentication token manipulation error
passwd: password unchanged
Further down the post, this recommendation to remount / solved my issue:
mount -rw -o remount /
Then I did passwd and the change worked this time.
