Description of problem:
Logwatch kernel module prints duplicate port entries in low detail
mode, which isn't particulary usefull. Better way would be to remove
On an example, instead of printing:
From 126.96.36.199 - 8 packets to tcp(22,22,22,22,22,22,22,25)
It could just print
From 188.8.131.52 - 8 packets to tcp(22,25)
Much more readable. Also, if there were more than 10 packets, but for
only two or three services, current logwatch would only print that
there were xxx packets from particular host. With duplicates removal,
it would print three services that were affected.
Simple patch is included.

Updated patch. In previous one there was incorrect assumption that port list
is sorted (which it isn't). It's fixed in this one.

SortIP function can now handle IPv6.
Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
The devel version (logwatch-7.1) is fixed.
