Anybody else noticing an increase lately, in the number of break-in attempts via SSH? I'm seeing more and more things like this, over the last few weeks: ----- Forwarded message from logcheck@localhost ----- > Date: Tue, 26 Apr 2005 10:02:16 -0400 (EDT) > From: logcheck@localhost > To: root@localhost > Subject: mail 2005-04-26 10:02 Security Events > > This email is sent by logcheck.
