Hi all, 

I am trying to use the SNOOP protocol implementation (for
FreeBSD), which is given at 
http://nms.lcs.mit.edu/software/snoop/
The implementation provides files which are to be replaced in directories
like "/usr/src/sys/netinet" , "/usr/src/sys/sys".
I have replaced the original files (tcp_input.c, tcp_var.h,
tcp_usrreqs.c, tcp.h, etc.>  in the above mentioned directories
with the new files given in this implementation. 
While trying to build the kernel with these new files the compilation
fails.
The errors which i get during compilation are :

---------------------------------------------------
/usr/src/sys/netinet/in_proto.c:108: 'tcp_input' undeclared here (not in a
function)
/usr/src/sys/netinet/in_proto.c:108: initializer element is not constant
/usr/src/sys/netinet/in_proto.c:108: (near initialization for
'inetsw[2].pr_input')
/usr/src/sys/netinet/in_proto.c:108: 'tcp_ctlinput' undeclared here (not
in a
function)
/usr/src/sys/netinet/in_proto.c:108: initializer element is not constant
/usr/src/sys/netinet/in_proto.c:108: (near initialization for
'inetsw[2].pr_ctlinput')
/usr/src/sys/netinet/in_proto.c:108: 'tcp_ctloutput' undeclared here
(not in a
function)
/usr/src/sys/netinet/in_proto.c:108: initializer element is not constant
/usr/src/sys/netinet/in_proto.c:108: (near initialization for
'inetsw[2].pr_ctlouotput')

--------------------------------------------------------

The compilation stops after these errors.
Kindly advice me on the probable reason for this problem and the
solution.
Thanks in Advance.
