    NET-SNMP: Timeout: No Response from

    Hi 'body,
    I have a strange issue:
    I've installed
    net-snmp 5.3.1 on a RH Linux 2.6.18-8.el5PAE i686 i686 i386 GNU/Linux
    net-snmp 5.4.1 on a Ubuntu Hardy 2.6.24-16-generic x86_64 GNU/Linux

    once configured a community called root-community and started the service (service snmpd start) both installations act the same:
    #snmptranslate .
    #snmpget -v 2c -c root-community SNMPv2-MIB::sysUpTime.0
    Timeout: No Response from

    in snmpd.log I can see that snmpd receives requests each time:
    Connection from UDP: [XXX.XXX.XXX.XXX]:XXXXX

    using "ps aux" i can see that snmpd is started with this line:
    /usr/sbin/snmpd -Lsd -Lf /var/log/snmp.log -p /var/run/snmpd -a

    Stopping that service, when I tryied to start it directly from command line:
    #/usr/sbin/snmpd -Lsd -Lf /var/log/snmp.log -p /var/run/snmpd -a

    I get response! Every snmpget request is served!

    What is happening there?

    I've just discovered that using the /etc/init.d/snmpd script with start argument (/etc/init.d/snmpd start) just work!

    Is the service command the problem? Why?

  3. #3
    I've just found my answer.
    Reading man service the very first description line says:"service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /."

    So the problem is in the snmpd script which doesn't initialize it's env variables...Nice.

    Thank 'body, uh!
