仅为 localhost 配置 lua 韵律

Question

我想使用prosody 或者另一个 xmpp 服务器来测试我的 xmpp 机器人。我希望它只接受来自地址/本地主机的连接（不想配置防火墙来阻止访问）。我想知道完成此任务的最简单方法。

Answer 1

要仅允许来自本地主机的连接，请将服务器绑定到 127.0.0.1。将其绑定到 0.0.0.0 将允许来自任何主机的连接。

检查 http://prosody.im/doc/configure 并将 c2s_interface 和 s2s_interface 值更改为“127.0.0.1”

要允许来自其他地方的连接，但不允许来自任何地方，您需要配置防火墙来执行此操作。

感谢 Tuomas 我的 prosody.cfg.lua

-- Prosody XMPP Server Configuration
-- 
-- If it wasn't already obvious, -- starts a comment, and all 
-- text after it on a line is ignored by Prosody.
--
-- The config is split into sections, a global section, and one 
-- for each defined host that we serve. You can add as many host 
-- sections as you like.
--
-- Lists are written { "like", "this", "one" } 
-- Lists can also be of { 1, 2, 3 } numbers, etc. 
-- Either commas, or semi-colons; may be used
-- as seperators.
--
-- A table is a list of values, except each value has a name. An 
-- example table would be:
--
-- ssl = { key = "keyfile.key", certificate = "certificate.cert" }
--
-- Whitespace (that is tabs, spaces, line breaks) is mostly insignificant, so 
-- can 
-- be placed anywhere
-- that     you deem fitting.
--
-- Tip: You can check that the syntax of this file is correct when you have finished
-- by running: luac -p /etc/prosody/prosody.cfg.lua
-- If there are any errors, it will let you know what and where they are, otherwise it 
-- will keep quiet.
--
-- Good luck, and happy Jabbering!

-- Global settings go in this section
-- (ie. those that apply to all hosts)

Host "*"
    c2s_interface = "127.0.0.1"
    s2s_interface = "127.0.0.1"

    -- This is a (by default, empty) list of accounts that are admins 
    -- for the server. Note that you must create the accounts separately
    -- (see http://prosody.im/doc/creating_accounts for info)
    -- Example: admins = { "user1@example.com", "user2@example.net" }
    admins = { }

    -- This is the list of modules Prosody will load on startup.
    -- It looks for mod_modulename.lua in the plugins folder, so make sure that exists too.

                "private"; -- Private XML storage (for room bookmarks, etc.)

            -- Nice to have
                "legacyauth"; -- Legacy authentication. Only used by some old clients and bots.
                "version"; -- Replies to server version requests
                "uptime"; -- Report how long server has been running
                "time"; -- Let others know the time here on this server
                "ping"; -- Replies to XMPP pings with pongs
                "pep"; -- Enables users to publish their mood, activity, playing music and more
                "register"; -- Allow users to register on this server using a client and change passwords

            -- Required for daemonizing, and logging
                "posix"; -- POSIX functionality, sends server to background, enables syslog, etc.

            -- Other specific functionality
                --"console"; -- telnet to port 5582 (needs console_enabled = true)
                --"bosh"; -- Enable BOSH clients, aka "Jabber over HTTP"
                --"httpserver"; -- Serve static files from a directory over HTTP
              };

    -- These modules are auto-loaded, should you
