Hi Eric,

   Thanks for a fast reply.
I tried modprobe nfnetlink_log

this is what I get in dmesg

[2054919.049919] Netfilter messages via NETLINK v0.30.

gakumar@krishna-desktop:~/PacketFilter/libnetfilter_log-1.0.0/utils$
./nfulnl_test
binding nfnetlink_log to AF_INET
error during nflog_bind_pf()
gakumar@krishna-desktop:~/PacketFilter/libnetfilter_log-1.0.0/utils$

These are the contents of
gakumar@krishna-desktop:~/PacketFilter/libnetfilter_log-1.0.0/utils$
ls /usr/local/lib/
libnetfilter_log.a                   libnetfilter_log_libipulog.so.1
   libnfnetlink.a                       pkgconfig/
libnetfilter_log.la
