From b3aec70d785d338b1b643fece6606cd32addaf0c Mon Sep 17 00:00:00 2001 From: Dirk Gouders <gouders@et.bocholt.fh-gelsenkirchen.de> Date: Thu, 2 Aug 2012 22:20:16 +0200 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).
