From 6556bfde65b1d4bea29eb2e1566398676792eaaa Mon Sep 17 00:00:00 2001 From: Dirk Gouders Date: Fri, 10 Aug 2012 01:24:51 +0000 Subject: [PATCH] netconsole.txt: revision of examples for the receiver of kernel messages There are at least 4 implementations of netcat with the BSD-based being the only one that has to be used without the -p switch to specify the listening port. Jan Engelhardt suggested to add an example for socat(1). Signed-off-by: Dirk Gouders Signed-off-by: Cong Wang Signed-off-by: David S.
