Init() error
IPTablesAPIWrite
IPTablesAPIRead
}
IPTablesAPI interface covers all methods inside linux calls package needed to manage linux iptables rules.
type IPTablesAPIRead ¶
type IPTablesAPIRead interface {
// ListRules lists all rules within the specified chain.
ListRules(protocol L3Protocol, table, chain string) (rules []string, err error)
}
IPTablesAPIRead interface covers read methods inside linux calls package needed to manage linux iptables rules.
type IPTablesAPIWrite ¶
type IPTablesAPIWrite interface {
// CreateChain creates an iptables chain in the specified table.
CreateChain(protocol L3Protocol, table, chain string) error
// DeleteChain deletes an iptables chain in the specified table.
DeleteChain(protocol L3Protocol, table, chain string) error
// SetChainDefaultPolicy sets default policy in the specified chain. Should be called only on FILTER tables.
SetChainDefaultPolicy(protocol L3Protocol, table, chain, defaultPolicy string) error
// AppendRule appends a rule into the specified chain.
AppendRule(protocol L3Protocol, table, chain string, rule string) error
// DeleteRule deletes a rule from the specified chain.
DeleteRule(protocol L3Protocol, table, chain string, rule string) error
// protocol deletes all rules within the specified chain.
DeleteAllRules(proto L3Protocol, table, chain string) error
}
IPTablesAPIWrite interface covers write methods inside linux calls package needed to manage linux iptables rules.
type IPTablesHandler ¶
type IPTablesHandler struct {
// contains filtered or unexported fields
}
IPTablesHandler is a handler for all operations on Linux iptables / ip6tables.
func NewIPTablesHandler ¶
