(‘ftp-data’) rather than the socket/protocol notation.
If your /etc/services file is missing some application-level protocols that you consider useful, you can
populate it with entries from the Assigned Numbers RFC, number 1340. For example, you may find it use-
ful to add lines like
gopher 70/tcp
gopher 70/udp
kerberos 88/tcp
kerberos 88/udp
snmp 161/tcp
snmp 161/udp
nextstep 178/tcp
nextstep 178/udp
prospero 191/tcp
prospero 191/udp
x11 6000/tcp
if you’re using those applications, and if they’re not already in your /etc/services file as received from
your system’s manufacturer. If you augment your
/etc/services this way, then instead of using
entries like
pass !6000/tcp/syn/send
your
Filter could use entries like
pass !x11/syn/send
which is much more readable. A list of TCP and UDP service numbers and names, culled from the
Assigned Numbers RFC, is available in Examples/services.ex
.
