Support for nftables
salt.modules.nftables.
append
(table='filter', chain=None, rule=None, family='ipv4')¶Append a rule to the specified table & chain.
starting with the chain. Trying to force users to adapt to a new method of creating rules would be irritating at best, and we already have a parser that can handle it.
CLI Example:
salt '*' nftables.append filter input \
rule='tcp dport 22 log accept'
IPv6:
salt '*' nftables.append filter input \
rule='tcp dport 22 log accept' \
family=ipv6
salt.modules.nftables.
build_rule
(table=None, chain=None, command=None, position='', full=None, family='ipv4', **kwargs)¶Build a well-formatted nftables rule based on kwargs. A table and chain are not required, unless full is True.
If full is True, then table, chain and command are required. command may be specified as either insert, append, or delete. This will return the nftables command, exactly as it would be used from the command line.
If a position is required (as with insert or delete), it may be specified as position. This will only be useful if full is True.
If connstate is passed in, it will automatically be changed to state.
CLI Examples:
salt '*' nftables.build_rule match=state \
connstate=RELATED,ESTABLISHED jump=ACCEPT
salt '*' nftables.build_rule filter input command=insert position=3 \
full=True match=state state=related,established jump=accept
IPv6:
salt '*' nftables.build_rule match=state \
connstate=related,established jump=accept \
family=ipv6
salt '*' nftables.build_rule filter input command=insert position=3 \
full=True match=state state=related,established jump=accept \
family=ipv6
salt.modules.nftables.
check
(table='filter', chain=None, rule=None, family='ipv4')¶Check for the existence of a rule in the table and chain
starting with the chain. Trying to force users to adapt to a new method of creating rules would be irritating at best, and we already have a parser that can handle it.
CLI Example:
salt '*' nftables.check filter input \
rule='tcp dport 22 log accept'
IPv6:
salt '*' nftables.check filter input \
rule='tcp dport 22 log accept' \
family=ipv6
salt.modules.nftables.
check_chain
(table='filter', chain=None, family='ipv4')¶New in version 2014.7.0.
Check for the existence of a chain in the table
CLI Example:
salt '*' nftables.check_chain filter input
IPv6:
salt '*' nftables.check_chain filter input family=ipv6
salt.modules.nftables.
check_table
(table=None, family='ipv4')¶Check for the existence of a table
CLI Example:
salt '*' nftables.check_table nat
salt.modules.nftables.
delete
(table, chain=None, position=None, rule=None, family='ipv4')¶in its entirety, or the rule's position in the chain.
starting with the chain. Trying to force users to adapt to a new method of creating rules would be irritating at best, and we already have a parser that can handle it.
CLI Examples:
salt '*' nftables.delete filter input position=3
salt '*' nftables.delete filter input \
rule='tcp dport 22 log accept'
IPv6:
salt '*' nftables.delete filter input position=3 family=ipv6
salt '*' nftables.delete filter input \
rule='tcp dport 22 log accept' \
family=ipv6
salt.modules.nftables.
delete_chain
(table='filter', chain=None, family='ipv4')¶New in version 2014.7.0.
Delete the chain from the specified table.
CLI Example:
salt '*' nftables.delete_chain filter input
salt '*' nftables.delete_chain filter foo
IPv6:
salt '*' nftables.delete_chain filter input family=ipv6
salt '*' nftables.delete_chain filter foo family=ipv6
salt.modules.nftables.
delete_table
(table, family='ipv4')¶New in version 2014.7.0.
Create new custom table.
CLI Example:
salt '*' nftables.delete_table filter
IPv6:
salt '*' nftables.delete_table filter family=ipv6
salt.modules.nftables.
flush
(table='filter', chain='', family='ipv4')¶Flush the chain in the specified table, flush all chains in the specified table if chain is not specified.
CLI Example:
salt '*' nftables.flush filter
salt '*' nftables.flush filter input
IPv6:
salt '*' nftables.flush filter input family=ipv6
salt.modules.nftables.
get_rule_handle
(table='filter', chain=None, rule=None, family='ipv4')¶Get the handle for a particular rule
starting with the chain. Trying to force users to adapt to a new method of creating rules would be irritating at best, and we already have a parser that can handle it.
CLI Example:
salt '*' nftables.get_rule_handle filter input \
rule='tcp dport 22 log accept'
IPv6:
salt '*' nftables.get_rule_handle filter input \
rule='tcp dport 22 log accept' \
family=ipv6
salt.modules.nftables.
get_rules
(family='ipv4')¶Return a data structure of the current, in-memory rules
CLI Example:
salt '*' nftables.get_rules
salt '*' nftables.get_rules family=ipv6
salt.modules.nftables.
get_saved_rules
(conf_file=None)¶Return a data structure of the rules in the conf file
CLI Example:
salt '*' nftables.get_saved_rules
salt.modules.nftables.
insert
(table='filter', chain=None, position=None, rule=None, family='ipv4')¶Insert a rule into the specified table & chain, at the specified position.
If position is not specified, rule will be inserted in first position.
starting with the chain. Trying to force users to adapt to a new method of creating rules would be irritating at best, and we already have a parser that can handle it.
CLI Examples:
salt '*' nftables.insert filter input \
rule='tcp dport 22 log accept'
salt '*' nftables.insert filter input position=3 \
rule='tcp dport 22 log accept'
IPv6:
salt '*' nftables.insert filter input \
