Struct IPTables

pub struct IPTables {
    pub cmd: &'static str,
    pub has_check: bool,
    pub has_wait: bool,
    pub is_numeric: bool,
}

Contains the iptables command and shows if it supports -w and -C options. Use new method to create a new instance of this struct.

Fields

cmd: &'static str

The utility command which must be ‘iptables’ or ‘ip6tables’.

has_check: bool

Indicates if iptables has -C (–check) option

has_wait: bool

Indicates if iptables has -w (–wait) option

is_numeric: bool

Indicates if iptables will be run with -n (–numeric) option

Implementations

impl IPTables

pub fn get_policy( &self, table: &str, chain: &str, ) -> Result<String, Box<dyn Error>>

Get the default policy for a table/chain.

pub fn set_policy( &self, table: &str, chain: &str, policy: &str, ) -> Result<(), Box<dyn Error>>

Set the default policy for a table/chain.

pub fn execute( &self, table: &str, command: &str, ) -> Result<Output, Box<dyn Error>>

Executes a given command on the chain. Returns the command output if successful.

pub fn exists( &self, table: &str, chain: &str, rule: &str, ) -> Result<bool, Box<dyn Error>>

Checks for the existence of the rule in the table/chain. Returns true if the rule exists.

pub fn chain_exists( &self, table: &str, chain: &str, ) -> Result<bool, Box<dyn Error>>

Checks for the existence of the chain in the table. Returns true if the chain exists.

pub fn insert( &self, table: &str, chain: &str, rule: &str, position: i32, ) -> Result<(), Box<dyn Error>>

Inserts rule in the position to the table/chain.

pub fn insert_unique( &self, table: &str, chain: &str, rule: &str, position: i32, ) -> Result<(), Box<dyn Error>>

Inserts rule in the position to the table/chain if it does not exist.

pub fn replace( &self, table: &str, chain: &str, rule: &str, position: i32, ) -> Result<(), Box<dyn Error>>

Replaces rule in the position to the table/chain.

pub fn append( &self, table: &str, chain: &str, rule: &str, ) -> Result<(), Box<dyn Error>>

Appends rule to the table/chain.

pub fn append_unique( &self, table: &str, chain: &str, rule: &str, ) -> Result<(), Box<dyn Error>>

Appends rule to the table/chain if it does not exist.

pub fn append_replace( &self, table: &str, chain: &str, rule: &str, ) -> Result<(), Box<dyn Error>>

Appends or replaces rule to the table/chain if it does not exist.

pub fn delete( &self, table: &str, chain: &str, rule: &str, ) -> Result<(), Box<dyn Error>>

Deletes rule from the table/chain.

pub fn delete_all( &self, table: &str, chain: &str, rule: &str, ) -> Result<(), Box<dyn Error>>

Deletes all repetition of the rule from the table/chain.

pub fn list( &self, table: &str, chain: &str, ) -> Result<Vec<String>, Box<dyn Error>>

Lists rules in the table/chain.

pub fn list_table(&self, table: &str) -> Result<Vec<String>, Box<dyn Error>>

Lists rules in the table.

pub fn list_chains(&self, table: &str) -> Result<Vec<String>, Box<dyn Error>>

Lists the name of each chain in the table.

pub fn new_chain(&self, table: &str, chain: &str) -> Result<(), Box<dyn Error>>

Creates a new user-defined chain.

pub fn flush_chain( &self, table: &str, chain: &str, ) -> Result<(), Box<dyn Error>>

Flushes (deletes all rules) a chain.

pub fn rename_chain( &self, table: &str, old_chain: &str, new_chain: &str, ) -> Result<(), Box<dyn Error>>

Renames a chain in the table.

pub fn delete_chain( &self, table: &str, chain: &str, ) -> Result<(), Box<dyn Error>>

Deletes a user-defined chain in the table.

pub fn flush_table(&self, table: &str) -> Result<(), Box<dyn Error>>

Flushes all chains in a table.

pub fn set_numeric(&mut self, numeric: bool)

Set whether iptables is called with the -n (–numeric) option, to avoid host name and port name lookups
