their ttl). This can be used - in combination with the proper ipfw incantations - to make a firewall or router invisible to traceroute and other exploration tools. This behaviour is controlled by a sysctl variable (net.inet.ip.stealth) and hidden behind a kernel option (IPSTEALTH). Reviewed by: eivind, bde

#
|
|
# On the handling of kernel options
|
|
#
|
|
# All kernel options should be listed in LINT, with suitable
|
|
# descriptions. Negative options (options that make some code not
|
|
# compile) should be commented out; LINT should compile as much code
|
|
# as possible. Try to structure option-using code so that a single
|
|
# option only switch code on, or only switch code off, to make it
|
|
# possible to have a full compile-test. If necessary, you can include
|
|
# "opt_lint.h" and check for COMPILING_LINT to get maximum code
|
|
# coverage.
|
|
#
|
|
# All new options shall also be listed in either "conf/options" or
|
|
# "<machine>/conf/options.<machine>". Options that affect a single
|
|
# source-file <xxx>.[c|s] should be directed into "opt_<xxx>.h", while
|
|
# options that affect multiple files should either go in
|
|
# "opt_global.h" if this is a kernel-wide option (used just about
|
|
# everywhere), or in "opt_<option-name-in-lower-case>.h" if it affect
|
|
# only some files. Note that the effect of listing only an option
|
|
# without a header-file-name in conf/options (and cousins) is that the
|
|
# last convention is followed.
|
|
#
|
|
# This handling scheme is not yet fully implemented.
|
|
#
|
|
#
|
|
# Format of this file:
|
|
# Option name filename
|
|
#
|
|
# If filename is missing, the default is
|
|
# opt_<name-of-option-in-lower-case>.h
