Getting SNMPD to work on Ubuntu
Setting up snmpd on ubuntu seems easy, but i never got it full working. It was working locally, but not for a cacti setup from another server. The problem was that the default install of snmpd on Ubuntu starts the demon on the loopback interface only, refusing connections from other computers.
Edit /etc/default/snmpd to fix that:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | # This file controls the activity of snmpd and snmptrapd # MIB directories. /usr/share/snmp/mibs is the default, but # including it here avoids some strange problems. export MIBDIRS=/usr/share/snmp/mibs # snmpd control (yes means start daemon). SNMPDRUN=yes # snmpd options (use syslog, close stdin/out/err). #SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1' SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid' # snmptrapd control (yes means start daemon). As of net-snmp version # 5.0, master agentx support must be enabled in snmpd before snmptrapd # can be run. See snmpd.conf(5) for how to do this. TRAPDRUN=no # snmptrapd options (use syslog). TRAPDOPTS='-Lsd -p /var/run/snmptrapd.pid' # create symlink on Debian legacy location to official RFC path SNMPDCOMPAT=yes |
that’s it. To restart the snmp server enter $ sudo /etc/init.d/snmpd restart
