Newbie Admin: Query about xconsole output


I sent this to the debian-security list earlier today, but perhaps
this is a better forum for the inquiry?


Good morning, all...  I expect that this is the correct forum for
this question, but if not, please point me in the right direction?

I am working my way through an implementation of David Ranch's
TrinityOs installation, with my own modifications for Debian.
After locking down inet.d, and implementing a strong rc.firewall
(similar to the one used in the IPCHAINS Howto), I have been
receiving the following xconsole output fairly regularly:

-------------------------------------------------------------

Mar 27 09:49:20 trinos in.qpopper[26080]: connect from bran
Mar 27 09:49:20 trinos tcplogd: pop-3 connection attempt from unknown@bran [192.168.101.209] Mar 27 09:50:20 trinos icmplogd: destination unreachable from trinos [192.168.101.30] 

-------------------------------------------------------------

My network infrastructure looks like this:

        |- 192.168.101.0 (External LAN)
        |
        | |- 192.168.101.30 (External TrinOS Interface)-|
        | |                                             |
        |-|     {trinos}                                |
        | |                                             |
        | |- 192.168.180.1 (Internal TrinOS Interface) -|
        |
        |- 192.168.180.0 (Internal LAN)

I have an external machine (bran, 192.168.101.209) checking POP e-mail
every few minutes, but why does the above resemble an error message?  Do
I have something incorrectly configured (within the rc.firewall?), or am
I misreading this?


Thanks in advance for your assistance.
