dmesg bootup-info removed/overwritten by syslogd ?

[Rob]

Hi,

I wanted to see my original bootup messages again. So I typed
dmesg, but all I got were 'arplookup' lines.

I'm puzzled, where the bootup messages have gone?
I have two files in /var/log: dmesg.today and dmesg.yesterday
Both files are completely filled with this line:
    arplookup 147.46.50.254 failed: host is not on local network

Nothing else.

How can I see the original bootup messages from the kernel?
Do I have to reboot for that :( ?

Regards,
Rob.
