The iptables is deactivated in the new node: [r...@cevstream ~]# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination as well as the selinux, is deactivated also. Any other idea? I don't see the flag "dirty" in the new node. It has no service associated, i don't know if this can means anything...
