OK, I'll do that tomorrow.
But my memory tells me this:
- Host Unreachable should be ignored for an *existing* TCP connection (it is considered an transient error) - Host Unreachable should make a TCP connection *setup* fail
If this last rule doesn't apply what's the use of sending the HU anyway ? .. (well maybe some routing protocols/software use them ?)
