Odd log entry, nearly every hour - what is this?

    I've been running Tomato v1.17 on my Linksys WRT54G v1.0 without problems, and prior to that ran Tomato v1.14 successfully.

    Something I've noticed on my logs is that I get an odd "MARK" entry nearly every hour, but there's no real lead on where it's coming from. Here's an example from this morning:

    I'm considering turning off computers and the three Snap Servers on the home network, just to see if I can isolate the odd log entry by a process of elimination.

    In the meantime, have any of you Tomato folks seen something similar?

    Also, short of having the router reboot, is there a way I can clear the logs at leisure?

    It is just that, a "Mark". It's purpose is to show that news is still happening as opposed to assuming that no news is good news.

    You can adjust the "Mark" interval or disable it entirely.

    I was wondering that also. I was just too lazy to post.

    It's a "heartbeat" so to speak.

    Thanks for the info.

    You can even change the interval in Administration - logging

    Thanks, folks!

    I understand the utility for an hourly "All's Well" log entry, but it's also one less thing to wade through when reading the logs.

    Speaking of which, is there a way to empty the log cache without resetting the router?

    Who reads the logs directly on the router? Use a central syslog server. A decent syslog server would let you filter out the "MARK" lines. Syslogs shouldn't be purged.

    echo "">/var/log/messages.0

    at least that's the one the webif displays when clicking "view log". the one without the ".0" is probably the one kept by the kernel for the system.
