you might have "accidently" deleted your /etc/protocols
here is my ...
# protocols This file describes the various protocols that are
# available from the TCP/IP subsystem. It should be
# consulted instead of using the numbers in the ARPA
# include files, or, worse, just guessing them.
ip 0 IP # internet protocol, pseudo protocol number
icmp 1 ICMP # internet control message protocol
igmp 2 IGMP # internet group multicast protocol
ggp 3 GGP # gateway-gateway protocol
tcp 6 TCP # transmission control protocol
pup 12 PUP # PARC universal packet protocol
udp 17 UDP # user datagram protocol
idp 22 IDP # WhatsThis?
raw 255 RAW # RAW IP interface
