我成功安装了Prosody IM并在localhost中使用它。现在，我有两台计算机通过带有固定IP地址的交叉电缆连接(我检查它，发送了ping(。在其中一台计算机中安装了Jabber服务器，并且在两者中都安装了基于xmpp的客户端。
但是，此客户端无法解析我的服务器的名称，即使它位于同一主机中也是如此。例如，如果我有一个虚拟主机"lti.loc"，我的客户端(基于 aioxmpp(在尝试连接时会显示此错误：
ioxmpp.errors.MultiOSError: failed to connect to XMPP domain 'lti.loc': multiple errors: [Errno -2] Name or service not known
有一种工具或方式仅在本地网络的 SRV 记录中设置此服务？
更新：我找到了一个名为dnsmasq的工具，现在我正在正确配置它。如果有人对此配置有更多了解，请回答。
我找到了一个解决方案：
首先，需要安装 dnsmasq。
之后，禁用系统名称的解析非常重要。在基于 Ubuntu 的系统中，命令是：
$ sudo systemctl disable systemd-resolved
$ sudo systemctl stop systemd-resolved
让我们配置 dnsmasq 配置文件来定位 Prosody 服务器。打开文件的命令是：
$ sudo gedit /etc/dnsmasq.conf
配置示例为：
local=/localnet/
address=/lti.loc/192.168.1.1
srv-host=_xmpp-client._tcp.lti.loc,lti.loc,5222
srv-host=_xmpp-server._tcp.lti.loc,lti.loc,5269
最后，使用以下命令启动 dnsmasq：
$ sudo systemctl start dnsmasq
某些应用程序需要 SSL 才能连接到韵律。韵律有自动生成这个的命令。最终的 Prosody 配置文件/etc/prosody/prosody.cfg.lua 看起来像这样：

}
-- These modules are auto-loaded, but should you want
-- to disable them then uncomment them here:
modules_disabled = {
-- "offline"; -- Store offline messages
-- "c2s"; -- Handle client connections
-- "s2s"; -- Handle server-to-server connections
-- "posix"; -- POSIX functionality, sends server to background, enables syslog, etc.
}
-- Disable account creation by default, for security
-- For more information see https://prosody.im/doc/creating_accounts
allow_registration = true
-- Force clients to use encrypted connections? This option will
-- prevent clients from authenticating unless they are using encryption.
c2s_require_encryption = false
-- Force servers to use encrypted connections? This option will
-- prevent servers from authenticating unless they are using encryption.
-- Note that this is different from authentication
s2s_require_encryption = false
-- Force certificate authentication for server-to-server connections?
-- This provides ideal security, but requires servers you communicate
-- with to support encryption AND present valid, trusted certificates.
-- NOTE: Your version of LuaSec must support certificate verification!
-- For more information see https://prosody.im/doc/s2s#security
s2s_secure_auth = false
allow_unencrypted_plain_auth = false
disable_sasl_mechanisms = { "DIGEST-MD5" }
-- Some servers have invalid or self-signed certificates. You can list
-- remote domains here that will not be required to authenticate using
-- certificates. They will be authenticated using DNS instead, even
-- when s2s_secure_auth is enabled.
--s2s_insecure_domains = { "insecure.example" }
-- Even if you leave s2s_secure_auth disabled, you can still require valid
-- certificates for some domains by specifying a list here.
--s2s_secure_domains = { "jabber.org" }
-- Select the authentication backend to use. The 'internal' providers
-- use Prosody's configured data storage to store the authentication data.
-- To allow Prosody to offer secure authentication mechanisms to clients, the
-- default provider stores passwords in plaintext. If you do not trust your
-- server please see https://prosody.im/doc/modules/mod_auth_internal_hashed
-- for information about using the hashed backend.
authentication = "internal_hashed"
-- Select the storage backend to use. By default Prosody uses flat files
-- in its configured data directory, but it also supports more backends
-- through modules. An "sql" backend is included by default, but requires
-- additional dependencies. See https://prosody.im/doc/storage for more info.
--storage = "sql" -- Default is "internal"
-- For the "sql" backend, you can uncomment *one* of the below to configure:
--sql = { driver = "SQLite3", database = "prosody.sqlite" } -- Default. 'database' is the filename.
--sql = { driver = "MySQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
--sql = { driver = "PostgreSQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
-- Archiving configuration
-- If mod_mam is enabled, Prosody will store a copy of every message. This
-- is used to synchronize conversations between multiple clients, even if
-- they are offline. This setting controls how long Prosody will keep
-- messages in the archive before removing them.
archive_expires_after = "1w" -- Remove archived messages after 1 week
-- You can also configure messages to be stored in-memory only. For more
-- archiving options, see https://prosody.im/doc/modules/mod_mam
-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
log = {
info = "prosody.log"; -- Change 'info' to 'debug' for verbose logging
error = "prosody.err";
-- "*syslog"; -- Uncomment this for logging to syslog
-- "*console"; -- Log to the console, useful for debugging with daemonize=false
}
-- Uncomment to enable statistics
-- For more info see https://prosody.im/doc/statistics
-- statistics = "internal"
-- Certificates
-- Every virtual host and component needs a certificate so that clients and
-- servers can securely verify its identity. Prosody will automatically load
-- certificates/keys from the directory specified here.
-- For more information, including how to use 'prosodyctl' to auto-import certificates
-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates
-- Location of directory to find certificates in (relative to main config file):
--certificates = "certs"
----------- Virtual hosts -----------
-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
-- Settings under each VirtualHost entry apply *only* to that host.
pidfile = "prosody.pid" -- stores prosody.pid in the current directory
VirtualHost "lti.loc"
ssl = {
key = "/var/lib/prosody/lti.loc.key";
certificate = "/var/lib/prosody/lti.loc.crt";
}
最后，在/etc/host/中正确设置主机很重要！
