Subject: I broke my port numbers :(
Date: Mon, 15 Jan 2007 23:55:15 +0200 [thread overview]
Message-ID: <20070115215515.GA3771@m.safari.iki.fi> (raw)
I know this may be entirely my fault but I have tried reversing
all of my _own_ patches I applied to 2.6.19.2 but can't find what broke this.
I did three times "netcat 127.0.0.69 42", notice the different
port numbers.
First, if someone could attempt this on 2.6.19.2 or 2.6.20-rc* ,
and tell it works, I shut up.

If something was listening on port 42, it would see the wrong port,
e.g. 23287, 20161 or 52470, not 52935, 52936 or 52937.
