Symptoms
-
Imunify360's UI is unaccessible with the following error:
Imunify agent is not running
-
The steps described in the troubleshooting article do not help.
-
Imunify360 is installed inside Virtuozzo container:
# hostnamectl status | grep Virtualization
Virtualization: openvz
# cat /proc/user_beancounters
Version: 2.5
... -
iptables commands fail with the error:
# iptables -A INPUT -s 8.8.8.8 -j ACCEPT
iptables v1.8.4 (nf_tables): CHAIN_ADD failed (Device or resource busy): chain INPUT -
An older version of iptables is installed on the server node, e.g.:
[root@servernode ~]# nft -v
nftables v0.8 (Joe Btfsplk)
[root@servernode ~]# iptables -V
iptables v1.4.21
[root@container ~]# nft -v
nftables v0.9.3 (Topsy)
[root@container ~]# iptables --version
iptables v1.8.4 (nf_tables)
Cause
A mismatch of iptables version installed on the hardware node and inside the container. The server node uses legacy iptables, the guest uses nf_tables variant.
Resolution
- Disable nftables and enable iptables inside the container.
OR:
- Upgrade iptables on the server node.
