I try to setup librenms monitoring server in a lxc container. I can monitor my switch, a qnap nas, a vm but i'm unable to get it working for a proxmox host. i installed snmpd with a standard debian conf. The service start without problem and is active. But when i try snmpwalk from proxmox host or from nms server i have a timeout. Still the snmpd service remains active. I tried to restart the container i see this in /var/log/messages on the host: Code: pve kernel: [511726.443462] audit: type=1400 audit(1543264741.686:173): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxc-108_</var/lib/lxc>" name="/" pid=953 comm="(ionclean)" flags="rw, rslave Here is the conf file of the container: Code: arch: amd64 cores: 1 hostname: nms memory: 512 net0: name=eth0,bridge=vmbr0,hwaddr=2E:76:DB:26:95:E2,ip=dhcp,type=veth ostype: debian rootfs: local-lvm:vm-108-disk-0,size=16G swap: 512 Edit: I can add that starting and stopping snmpd service is fast. Once i have run a snmpwalk stopping service or geeting its status is very slow. Edit2: with ss -ulnp i can see proxmox host is not listening port udp 161. It's not listening at all and yet systemctl status snmpd tells me snmpd service is running fine.
