Messages Log extract - what does it mean?
« on: May 21, 2005, 11:14:18 PM »
I'm posting an extract from my Message Log and ask if someone can tell me what it is really telling me as the log contains heaps of similar entries.

It means your firewall is doing its job, do not worry about it.  If you are sick and tired watching these entries, you can issue the following command from the prompt when logged in as root:

/sbin/e-smith/db configuration setprop masq Logging none
followed by:
/sbin/e-smith/signal-event remoteaccess-update

If it does not work out of the box, please fill in a Bug Report @ Bugzilla (http://bugs.contribs.org)  - check: http://wiki.contribs.org/Bugzilla_Help .  Thanks.

Thank you Burnat ... I thought this might have been the case but I did need an 'expert' to confirm for me.

I'll leave the logging on for a bit but I noted your commands for possible use.

Paul, I am no expert believe me, just struggling...  Note that there is an enournous amount of knowledge on the site accessible by doing a search on words of interest... When you do, ensure that you click "show all results"

SRC=60.41.210.7  - Originating IP
DST=192.168.0.22  - Lan IP that packets were destined for
PROTO=TCP  - Protocol used
SPT=4558   -  Source Port
DPT=445  - Destination Port

This looks like a WinNT based box that has a virus and the virus is doing a scan to find another NT based box to infect.  FWIW, Port 445 is the new Netbios port; it took over for ports 135 - 139.
