Ufw Allow Openssh Access

Sudo ufw enable First Command allows ssh port 22 from the Ubuntu firewall, Then we enable the firewall using ufw command. You will receive the following message Firewall is active and enabled on system startup You can view the ufw firewall status using ufw status command. 1.关闭ubuntu的防火墙 ufw disable 2.卸载了iptables apt-get remove iptables. 1.用iptables -F这个命令来关闭防火墙,但是使用这个命令前,千万记得用iptables -L查看一下你的系统中所有链的默认target,iptables -F这个命令只是清除所有规则,只不会真正关闭iptables.想象一下,如果你的链默认target是DROP,本来你有规则来允许一些.

Manage firewall with UFW.

The below requirements are needed on the host that executes this module.

ufw package

Parameter	Choices/Defaults	Comments
comment string	Add a comment to the rule. Requires UFW version >=0.35.
default string	Choices: allow deny reject	Change the default policy for incoming or outgoing traffic.
delete	Choices: no ← yes
direction	Choices: in incoming out outgoing routed	Select direction for a rule or default policy command. Mutually exclusive with interface_in and interface_out.
from_ip string	Default:	Source IP address.
from_port	Source port.
insert integer	Note that ufw numbers rules starting with 1.
insert_relative_to string	Choices: first-ipv4 first-ipv6 last-ipv4 last-ipv6	Allows to interpret the index in insert relative to a position. `zero` interprets the rule number as an absolute index (i.e. 1 is the first rule). `first-ipv4` interprets the rule number relative to the index of the first IPv4 rule, or relative to the position where the first IPv4 rule would be if there is currently none. `last-ipv4` interprets the rule number relative to the index of the last IPv4 rule, or relative to the position where the last IPv4 rule would be if there is currently none. `first-ipv6` interprets the rule number relative to the index of the first IPv6 rule, or relative to the position where the first IPv6 rule would be if there is currently none. `last-ipv6` interprets the rule number relative to the index of the last IPv6 rule, or relative to the position where the last IPv6 rule would be if there is currently none.
interface string	Specify interface for the rule. The direction (in or out) used for the interface depends on the value of direction. See interface_in and interface_out for routed rules that needs to supply both an input and output interface. Mutually exclusive with interface_in and interface_out.
interface_in added in 0.2.0 of community.general	Specify input interface for the rule. This is mutually exclusive with direction and interface. However, it is compatible with interface_out for routed rules.
interface_out added in 0.2.0 of community.general	Specify output interface for the rule. This is mutually exclusive with direction and interface. However, it is compatible with interface_in for routed rules.
log	Choices: no ← yes
logging	Choices: on off low medium high full	Toggles logging. Logged packets use the LOG_KERN syslog facility.
name string	aliases: app
proto string	Choices: any tcp udp ipv6 esp ah gre igmp	aliases: protocol
route boolean	Choices: yes	Apply the rule to routed/forwarded packets.
rule string	Choices: allow deny limit reject
state	Choices: disabled enabled reloaded reset	`enabled` reloads firewall and enables firewall on boot. `disabled` unloads firewall and disables firewall on boot. `reset` disables and resets firewall to installation defaults.
to_ip string	Default:	Destination IP address.
to_port	Destination port.
