when I enter dmesg | grep foo in a terminal I get nil output.
If I enter dmesg on it's own, I get a stream like the last few lines listed below:
Shorewall:net2fw
ROP:IN=eth0 OUT= MAC=00:14:85:1f:2c:57:00:1b:11:0d:83:27:08:00 SRC=10.1.1.1 DST=10.1.1.3 LEN=407 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=2050 DPT=1730 LEN=387

Why is this, and what do I need to do to restore dmesg output to display settings???
