I love computers, they have such a strange sense of humor.  ;-) 
 
This is what happened: 
 
sedwards at marconi:sedwards$ unset LD_PRELOADConnection to 
itsallgoodradio.net closed by remote host. 
Connection to itsallgoodradio.net closed. 
[sedwards at edison sedwards]$ ssh itsallgoodradio.net 
ssh_exchange_identification: Connection closed by remote host 
 
Is there anything besides dmesg that I should check when someone gets to 
the console (assuming they can login at the console), before rebooting? 
 
Thanks
