Problem With IPTABLES Logging Message To The Screen/console

Hi

I am not sure how to solve this.

I am constantly getting messages that should go into the kern/message log printed on screen – MOSTLY from iptables. The messages are ALSO logged to the syslog files.

It still prints those message onto the console screen even if I am logged off (security issue).

When logged in on the console its anoying as I constantly have to hit CTRL-L to refresh the screen to get rid of those messages.

However it does NOT happen when I SSH into the machine.

How can I solve this that those messages are NOT printed.

thanks Jobst

  • I think you are after *dmesg -n alert*

    man dmesg

    -n, –console-level level
    Set the level at which printing of messages is done to the con‐
    sole. The level is a level number or abbreviation of the level
    name. For all supported levels see the –help output.

    For example, -n 1 or -n alert prevents all messages, except
    emergency (panic) messages, from appearing on the console. All
    levels of messages are still written to /proc/kmsg, so sys‐
    logd(8) can still be used to control exactly where kernel mes‐
    sages appear. When the -n option is used, dmesg will not print
    or clear the kernel ring buffer.
