Hi!

  I'm running snort 1.7 in linux box with kernel 2.4.3.

  The command line to start snort is:

   ./snort -A full -c snort.conf -d -D -u snort -g snort -h 192.168.10.0/24 
-s -M wrk.conf -i ppp0 -l /var/log/snort -v

  Work good but my /var/log/messages is full (90%) of:

   "Jul 1 12:58:23 gateway snort[757]: [!] WARNING: Not IPv4 datagram! ([ver: 
0x2][len: 0x2e2e])"

  what that messages means?

Some corrupted/strange/odd datagram has been received. Although len
0x2e2e looks _DODGY_! :)
