File README.SuSE of Package net-snmp.507

Our net-snmp package was audited by Thomas Biege of the SuSE Security team
prior to the release of CERT Advisory CA-2002-03.  Of course, this
is not a guarantee that future problems will not be found and does not
address flaws and insecurities inherent in software as powerful and
complex as an SNMP implementation.  Because of this 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-snmp.log instead
        of sending stderr/stdout through syslog.  If you don't want logging,
        remove the '-l /var/log/net-snmp.log' from /etc/init.d/snmpd.

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 example init
        script in /usr/share/doc/packages/net-snmp/rc.snmptrapd.  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 install the script,
          install rc.snmptrapd /etc/init.d/snmptrapd
          chkconfig snmptrapd on
          ln -s ../../etc/init.d/snmptrapd /usr/sbin/rcsnmptrapd.
        and create a configuration file named /etc/snmp/snmptrapd.conf.  Then,
        start the daemon with
          rcsnmptrapd start
        Logging is done to /var/log/net-snmptrapd.log.

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

o Master agentx support is enabled if you have modules in
        /usr/lib/net-snmp/--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.
