Set the method to be used for network locking/unlocking. Locking is done to ensure that tcp packets are dropped between dump and restore. This is done to avoid the kernel sending RST when a packet arrives destined for the dumped process.
Currently two methods are available:
- iptables
- Use iptables rules to drop the packets. This is the default if 'method' is not specified.
- nftables
- Use nftables rules to drop the packets.
