Bug description:
>From some particular web servers, a machine running feisty cannot get an HTTP response. However, machines running most other OSs can get an HTTP response. (However, the problem appears to affect Debian etch also.)
How to reproduce the problem:
Use wget or any web browser to try to retrieve the file from this URL:
http://www.ureg.ohio-state.edu/ourweb/online.html
The client resolves the host, establishes a connection, and sends an HTTP request. However, it receives no response. However, a client on other OSs besides feisty will receive a response. In fact, a machine running dapper can get an HTTP response just fine.
Here is the output from wget:
