Security Question

[Paul Speck <paul.speck () Solveris com>]

I am attaching log files whichshow  two days of attack and then an IP Spoof.
Is this an indication of a successful access of our Red Hat 7.1 Linux
machine?  The Firewall manufacture (SonicWall) says no, but I am not sure of
that.  The MAC address is our Linux box.  On the IP Spoof, neither Source
nor Destination are on our LAN.
