Bug Description

Binary package hint: netcat

I am on the Maverick beta amd64, latest updates.

When I pipe content into netcat, it doesn't give me any output. Entering the commands manually works fine.

felix@felix-laptop:~/Desktop$ echo "GET / HTTP/1.0\n\n" | nc -v ubuntu.com 80
Connection to ubuntu.com 80 port [tcp/www] succeeded!
felix@felix-laptop:~/Desktop$ nc -v ubuntu.com 80

The short answer is to do:
echo "GET / HTTP/1.0\n\n" | nc -v ubuntu.com 80 -q -1
