View File README.SUSE of Package net-snmp (Project openSUSE:Factory)

An SNMP agent is a powerful and complex software and, as such, may
be affected by flaws and security issues.  We recommend that SNMP
access (161/udp,162/udp) be blocked at your firewall.

There are also some important changes that have been made in this release
of our package:

      o the daemon now sets a PID file in /var/run/

      o logging is now done directly to /var/log/net-snmpd.log instead
        of sending stderr/stdout through syslog.

      o the daemon is now started with the '-r'.  This option prevents
        snmpd from exiting if it doesn't have permission to read something.
        This only occurs if you start snmpd on a high port as a non-root
        root user.

      o If you need to run snmptrapd, we've provided an init script
        in /etc/init.d/snmptrapd, but the service is disabled by default.
        SNMP traps should be avoided whenever possible because they are
        unreliable (you should poll with snmpget instead) and snmptrapd
        has been the source of many of the security problems with SNMP
        so please don't run this unless you are sure of what you are doing.
        To enable the service, run
          chkconfig snmptrapd on
        and create a configuration file named /etc/snmp/snmptrapd.conf.
        Then, start the daemon with
          rcsnmptrapd start
        Logging is done to /var/log/net-snmpd.log.

        For more information see the manpages for snmptrapd and snmptrapd.conf.

      o Master AgentX support is enabled if you have modules in
        /usr/lib/net-snmp/agents. The domain socket is created as
        /var/run/agentx/master.  You can change this to a network
        interface if needed (see snmpd(1)).  The snmpd init script
        automatically detects and starts any sub-agents in placed into
        /var/lib/net-snmp.
