Guys,

One of my boxes reported the following connection attempts today:

Source: 139.134.5.142                    11 entries,         5 destinations

Because:

a) Not an automated scan
b) Not any ports I can find in the database
c) Doesn't seem to misdirected ASCII
d) Origin shows as mail8..bigpond.com.au

I thought I'd ask the list to enlighten me before I try mailing the contact
address.

Any ideas?

Regards,

tom.
