Ufw Allow OpensshOpenssh

Sudo ufw allow 8080/tcp Opening Port Ranges # With UFW, you can also allow access to port ranges. When opening a range, you must specify the port protocol. For example, to allow ports from 7100 to 7200 on both tcp and udp, run the following command: sudo ufw allow 7100:7200/tcpsudo ufw allow 7100:7200/udp Allowing Specific IP Addresses #. # Allow everything and enable UFW-ufw: state: enabled policy: allow # Set logging-ufw: logging: on # Sometimes it is desirable to let the sender know when traffic is # being denied, rather than simply ignoring it. In these cases, use # reject instead of deny. In addition, log rejected connections:-ufw: rule: reject port: auth log: yes # ufw supports connection rate limiting, which is useful. Aug 20, 2020 sudo ufw allow PORT. As an example, let us allow access through the default OpenSSH port (Port 22). Sudo ufw allow 22 Specifying the Protocol for the Port to be Allowed On. Using this simplified syntax, you can specify the protocol that you want the port to access. By specifying the protocol, you will not be able to access it using any other. 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.

To install it use: ansible-galaxycollectioninstallcommunity.general.

To use it in a playbook, specify: community.general.ufw.

Set Up Default Policies. UFW is installed on Ubuntu by default. If it has been uninstalled for some.

from_ip
string
Default:

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
