I often do some work while on the train home, and I have noticed that 1.6.0 won't let me connect from the command line when I have no network connection.
When online:
matt@matt-laptop:~$ ./mongodb-linux-x86_64-1.4.4/bin/mongo webgenius
MongoDB shell version: 1.4.4
url: webgenius
connecting to: webgenius
matt@matt-laptop:~$ ./mongodb-linux-x86_64-1.6.0/bin/mongo webgenius
MongoDB shell version: 1.6.0
connecting to: webgenius
When offline:
matt@matt-laptop:~$ ./mongodb-linux-x86_64-1.4.4/bin/mongo webgenius
MongoDB shell version: 1.4.4
url: webgenius
connecting to: webgenius
matt@matt-laptop:~$ ./mongodb-linux-x86_64-1.6.0/bin/mongo webgenius
