respectively logging and dropping ICMP REDIRECT packets.
Note that there is no rate limiting on the log messages, so log_redirect
should be used with caution (preferrably only for debugging purposes).
Prompted by docs/12343, in which people seemed to get a little confused.
The original text in the file said:
[...]
# By default we use COM1 as our serial console port *if* we're going to use
# a serial port as our console at all. (0x3E8 = COM2)
#
#BOOT_COMCONSOLE_PORT= 0x3F8
[...]
From what I can make out, some people have assumed that means that if
they just uncomment the BOOT_COMCONSOLE_PORT then it will use COM2:
These same people then assume that "0x3F8" on that line is a typo for
"0x3E8".
What it actually means is that if you uncomment the line then the default
stays as "Ox3F8" (COM1:), and that you have to uncomment the line, *and*
change the value of the variable in order to use COM2:.
So I've made that a little bit clearer. I've also listed the hex values
for COM1: thru COM4:, snarfed from sys/isa/isareg.h.

revert this change.

This makes it a lot easier to deal with machines that constantly change
their network configuration as you can leave ifconfig settings for all
the possible cards - just the ones that are present will be configured.

Perhaps this default value can be inappropriate,

not specified wrapping is turned off so that inetd will behave exactly
as it used to before TCP Wrappers was imported.
Change etc/defaults/rc.conf so as to encourage wrapping on new systems.
Clarify the use of TCP Wrappers in the IMPLEMENTATION NOTES of the

Do discard standard output from the sysctl for approxy_all, and echo
what this sysctl is doing in the usual way. This fix is probably
backwards. We should probably just use the standard sysctl output
in all cases (it needs to have a newline filtered out).
Echo what the sysctls for nfs_reserved_port_only and nfs_access_cache

Despite their name it doesn't keep TCP sessions alive, it kills
them if the other end has gone AWOL. This happens a lot with
clients which use NAT, dynamic IP assignment or which has a 2^32
* 10^-3 seconds upper bound on their uptime.
There is no detectable increase in network trafic because of this:
two minimal TCP packets every two hours for a live TCP connection.
Many servers already enable keepalives themselves.
The host requirements RFC is 10 years old, and doesn't know about
the loosing clients of todays InterNet.
