Hi, i'd like to use and learn more about SNMP protocole. I havegot some pbs with it under my FC3/770kernel : Here are the results of sh commands : [root@nsl3 ~]# ps -ef | grep snm root 4690 1 0 20:08 ? 00:00:00 /usr/sbin/snmptrapd -Lsd -p /var/run/snmptrapd.pid root 23090 1 0 23:37 ? 00:00:00 /usr/sbin/snmpd -Lsd -Lf /dev/null -p /var/run/snmpd -a root 23104 22795 0 23:37 pts/2 00:00:00 grep snm [root@nsl3 ~]# telnet 127.0.0.1 161 Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host: Connection refused [root@nsl3 ~]# more /etc/snmp/snmpd.conf rocommunity nsl disk / 10000 [root@nsl3 ~]# i don't know why i can't access on snmpd daemon to use it under nagios . Any help will be welcome. Regards Emmanuel
