Interesting observations in the logs.  

When the SSH zlib problem came up, I had lots of port 22 entries in the
logs for awhile.  

Until Monday I had not been nmaped port scanned in a long long time.  It
appears like the hackers like to use class C range scans on one port.  I
have two dachstein firewalls on @cox network.  I see the same ip
addresses hitting on port, say, 21 about one hour and a half a part from
each other. Both firewalls use the same time server to keep the clocks
maintained.  

When the privilege escalation OpenSSH problem was announced there were
no new 22 port scans noted.  In fact I had 11 port scans for port 21
over two days on July 1 and 2.  That was out of 16 logged.  July 3 is a
pre holiday day and the Deny messages are light. I finally have 4 port
22 denies, and 2 port 21 deny out of 8 denies logged.
