get a list of interfaces, and then automatically configure them if
${ifconfig_${ifn}} or /etc/start_if.${ifn} exists.
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.
and set it to "/etc/pccard.conf.sample" in /etc/defaults/rc.conf.
Perhaps this default value can be inappropriate,
but I set to this value for the convenience of PC-card boot.flp users.
Please correct it if there are better solutions.
commentary. :) 3rd and final frob of this. Leave enough comments
behind that anyone running into trouble at least has some cited clues
on dealing with it and jump into the brave new world with uncommented
IANA port assignments.
twice to enable wrapping for internal wrapping as well. If the option is
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
manual page.

the old STREAM protocol has been obsoleted by "ST2" (RFC 1819)

- included all registered protocols, so it's now a useful reference as well
- renamed title to reflect new content
(deleted word "IP", since all registered internet protocols are included now)
- corrected URL (file isn't hosted by iana.org anymore)
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
are doing.
default.
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.
