what the daemon does - it is a relayer that pays attention to the status
of pools of hosts; not a status checkers that happens to do some relaying

split the code to start the event loop in two functions.
introduce merge_config which will be used later on.
|
|
First split out hosts, tables and services into to structs, one that
contains the runtime fields and one (inside the runtime) that contains
mostly static fields that will be sent over the socket during reload.
Also move the demoted field of tables inside the flags field as its
just a boolean.

usage. also modify the check_icmp code to use non-blocking raw sockets
and merge the icmp4 and icmp6 functions. some other minor changes
while i'm here.

(this code needs some more work to implement a better icmp handling,
but this will fix a serious bug for now)

and we don't know about all the possible security problems.
change the check send/expect code to use the fnmatch(3) interface
using shell globbing rules instead. this allows simple patterns like
"220 * ESMTP*" or "SSH-[12].??-*".

regex(3)). this allows to define additional checks for other TCP
protocols.

seconds (tv_sec) and microseconds (tv_usec), but the code assumed
seconds and milliseconds...

instead of nested select() calls and to handle the non-blocking
sockets properly.

remote hosts and dynamically alter pf(4) tables and redirection rules
for active server load balancing. The daemon has been written by
Pierre-Yves Ritschard (pyr at spootnik.org) and was formerly known as
"slbd".
The daemon is fully functional but it still needs some work and
cleanup so we don't link it to the build yet. Some TODOs are a
partial rewrite of the check_* routines (use libevent whenever we
can), improvement of the manpages, and general knf and cleanup.
