I am trying to make snmpd listen on a specific address for the JAIL HOST(aka physical server) and each jailed environment (aka JAIL). The server is server configured using the ezjail framework. As I read "man (8) snmpd", I should be able to do this. I am trying to make the JAIL HOST listen on udp:161 192.168.222.90 and a JAIL to listen on udp:161 192.168.222.91 obviously, each JAIL alias IP would be distinct for each jailed environment. I have edited JAIL HOST /usr/local/etc/snmp/snmpd.conf to include "agentaddress udp:161 192.168.2222.90" Where do I profile this? How do I make this work? What am I doing wrong? I am humbly asking for assistance :) Thanks Don =============== Section: Net-SNMP (8) SNMPD SYNOPSIS snmpd [OPTIONS] [LISTENING ADDRESSES] -x ADDRESS Listens for AgentX connections on the specified address rather than the default "/var/agentx/master". The address can either be a Unix domain socket path, or the address of a network interface. The format is the same as the format of listening addresses described below. ============== ==== some of my notes === JAIL Host hier, separate partition for jails /usr/jails basejail & newjail /usr/jails/basejail /usr/jails/newjails I did not modify the ezjail.conf file >From JAIL HOST # mount_procfs proc /usr/jails/web/proc >From within the JAIL I installed /usr/ports/net-mgmt/net-snmp # make # make install clean mkdir /snmp in /usr/local/etc create snmpd.conf file # cp /usr/local/share/snmp/snmpd.conf.example /usr/local/etc/snmp/snmpd.conf Made minial changes to snmpd.conf in JAIL Host and JAIL. # sec.name source community # com2sec local localhost public com2sec local 192.168.222.91 public com2sec mynetwork 192.168.222.0/24 public Added to JAIL rc.conf and JAIL HOST rc.conf # vi /usr/jails/web/etc/rc.conf snmpd_enable="YES" snmpd_flags="-a" snmpd_pidfile="/var/run/snmpd.pid" restart the JAIL >From JAIL # snmpwalk -c public -u com2sec -v 1 web system This does output allot of expected snmp data EXCEPT that it is listing the data for the JAIL HOST, not the JAIL. # less /var/log/snmpd.log init_kmem: kvm_openfiles failed: /dev/mem: No such file or directory
