For some, reason, iptables-save does not seem to be working in
unprivileged containers.
To reproduce:
- this adds a sample iptables rule:
# iptables -A INPUT -p tcp --dport 22 -j ACCEPT
- this lists the rule:
# iptables -L -v -n
Chain INPUT (policy ACCEPT 13166 packets, 5194K bytes)
pkts bytes target prot opt in out source
destination
0 0 ACCEPT tcp -- * * 0.0.0.0/0
0.0.0.0/0 tcp dpt:22
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source
destination
Chain OUTPUT (policy ACCEPT 12620 packets, 656K bytes)
pkts bytes target prot opt in out source
destination
- this is supposed to dump iptables rules to stdout - but it doesn't:
# iptables-save
#
Any idea how to make "iptables-save" working in unprivileged lxc
containers?
