+We see that this octet contains 2 bytes from the reserved field.

+We already mentioned that bits number 7 and 6 belong to the

+.PP
+The expression says "let the 13th octet of a TCP datagram have

+.PP
+Now, let's assume that we need to capture SYN packets, but we
+don't care if ACK or any other TCP control bit is set at the

+.PP
+Now bits 1 and 4 are set in the 13th octet. The binary value of

+     00010010
+.PP
+which translates to decimal
+.PP

+0*2 + 0*2 + 0*2 + 1*2 + 0*2 + 0*2 + 1*2 + 0*2   = 18
+.fi
+.PP
+Now we can't just use 'tcp[13] == 18' in the \fItcpdump\fP filter
+expression, because that would select only those packets that have
+SYN-ACK set, but not those with only SYN set. Remember that we don't care
+if ACK or any other control bit is set as long as SYN is set.
+.PP
+In order to achieve our goal, we need to logically AND the
+binary value of octet 13 with some other value to preserve
+the SYN bit. We know that we want SYN to be set in any case,
+so we'll logically AND the value in the 13th octet with
+the binary value of a SYN:
+.PP
+.nf
+
+          00010010 SYN-ACK              00000010 SYN

+.PP
+We see that this AND operation delivers the same result
+regardless whether ACK or another TCP control bit is set.
+The decimal representation of the AND value as well as
+the result of this operation is 2 (binary 00000010),
+so we know that for packets with SYN set the following

+On Linux systems with 2.0[.x] kernels:

+packet filtering cannot be done in the kernel, so that all packets must
+be copied from the kernel in order to be filtered in user mode;
+.IP
+all of a packet, not just the part that's within the snapshot length,
+will be copied from the kernel (the 2.0[.x] packet capture mechanism, if
+asked to copy only part of a packet to userland, will not report the
+true length of the packet; this would cause most IP packets to get an
+error from
+.BR tcpdump ).

+We recommend that you upgrade to a 2.2 or later kernel.

 Some attempt should be made to reassemble IP fragments or, at least
 to compute the right length for the higher level protocol.
