1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.
Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion

This is a mini-SNMP daemon. The basic daemon implements the system group
and a number of private extensions to manage the UDP transport mapping,
communities, trap destinations and loadable modules. In this form it can
be used to provide remote access to arbitrary data that can be described in
the form as required by the SMI. The daemon speaks both SNMPv1 and SNMPv2c.
One basic loadable module is provided together with the daemon:
- snmp_mibII provides the information groups for ip, tcp, and udp.
Installation
------------
As usual by doing:
configure [--with-libbegemot[=path]]
make
make install
This does not install a configuration file. The standard location for the
configuration is /etc/snmpd.config, but can be overwritten on the command
line. An example configuration file is provided. Use --with-libbegemot
to use libbegemot instead of libisc.
Running
-------
snmpd [-m name[=value]] [-p pid-file] [-c config-file] [-d] [-l prefix]
[-D debug-flags] [-I path]
-m defines a configuration macro. If no value is given it
is set to the empty string.
-p specify the file where to store the PID. Default is
/var/run/{prefix}.pid.
-c specify the configuration file. Default is /etc/{prefix}.config.
-d don't go into daemon mode.
-l specify the prefix. This is used for the default config and
pid file names and for the syslog. Default is "snmpd".
-D specify debug flags:
d dump all PDUs.
e debug event library.
-I specify the include path for system configuration files.
Default is /etc:/usr/etc:/usr/local/etc.
The directory snmpd contains a snmpd.sh script, which can be copied to
/usr/local/etc/rc.d to automatically start and stop the daemon. snmpd.config
is an example config script.
