New Raspbian “wheezy” installed on 8 GB SanDisk SDHC card

I obtained an 8 GB SD card and downloaded and installed using windows 7 a later drop of wheezy (2012-12-16-wheezy-raspbian.zip) on it using Win32DiskImager.

After booting I had to download and install avahi-daemon ('sudo apt-get install avahi-daemon') as before, but unlike with the previous version first I had update using 'apt-get update' due to some daemon libraries being missing.

Remote logins to the pi account were blocked due to a host key problem in the Pi. Here's the error message:


john@john-ThinkPad-T42:~$ ssh pi@raspberrypi.local
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the ECDSA key sent by the remote host is
d4:21:93:57:3e:18:79:9f:d3:f4:99:00:9a:c1:fe:59.
Please contact your system administrator.
Add correct host key in /home/john/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /home/john/.ssh/known_hosts:12
  remove with: ssh-keygen -f "/home/john/.ssh/known_hosts" -R raspberrypi.local
ECDSA host key for raspberrypi.local has changed and you have requested strict checking.
Host key verification failed.
john@john-ThinkPad-T42:~$ ^C



The new version has no root account, so privileged operations require sudo, which the 'pi' user has the ability to use.

I used raspi-config to change the keyboard to the 104 key pc style and expand the disk partition to the full 8 GB available on the SD card. 

The new version also shows the full 512 MB of ram, unlike the previous version.
