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
