# Wrapping sshd(8) is not normally a good idea, but if you
# need to do it, here's how
sshd : localhost : allow
sshd : ALL : allow

# Protect against simple DNS spoofing attacks by checking that the
# forward and reverse records for the remote host match. If a mismatch
# occurs, access is denied, and any positive ident response within
# 20 seconds is logged. No protection is afforded against DNS poisoning,
# IP spoofing or more complicated attacks. Hosts with no reverse DNS
# pass this rule.
ALL : PARANOID : RFC931 20 : deny

# Allow anything from localhost.  Note that an IP address (not a host
# name) *MUST* be specified for rpcbind(8).
ALL : localhost 127.0.0.1 : allow
# Comment out next line if you build libwrap without IPv6 support.
ALL : [::1] : allow

# To use IPv6 addresses you must enclose them in []'s
