# TURN listener port for UDP and TCP (Default: 3478).
# Note: actually, TLS & DTLS sessions can connect to the
# "plain" TCP & UDP port(s), too - if allowed by configuration.

# TURN为UDP和TCP的侦听器端口(默认: 3478)。
# 注:实际上,TLS和DTLS会话可以连接到"清晰的"TCP和UDP端口,——如果允许配置。

# TURN listener port for TLS (Default: 5349).
# Note: actually, "plain" TCP & UDP sessions can connect to the TLS & DTLS
# port(s), too - if allowed by configuration. The TURN server
# "automatically" recognizes the type of traffic. Actually, two listening
# endpoints (the "plain" one and the "tls" one) are equivalent in terms of
# functionality; but we keep both endpoints to satisfy the RFC 5766 specs.
# For secure TCP connections, we currently support SSL version 3 and
# TLS version 1.0, 1.1 and 1.2. SSL2 "encapculation mode" is also supported.
# For secure UDP connections, we support DTLS version 1.
#
# TURN为TLS的侦听器端口(默认: 5349)。
# 注意:事实上,"清晰的"TCP和UDP会话可以连接到TLS和DTLS端口，如果允许配置。
# TURN服务器"自动"识别传输类型。实际上,两个监听终端点("清晰的"端和"TLS"端)是
# 对等的功能;但我们保持两个端点来满足RFC 5766规范。
# 对于安全的TCP连接,我们目前支持SSL的3个版本，是TLS 1.0版本,1.1版本和1.2版本。
# SSL2还支持"encapculation模式"。对于安全的UDP连接,我们支持DTLS版本1。
#
#tls-listening-port=5349

# Alternative listening port for UDP and TCP listeners;
# default (or zero) value means "listening port plus one".
# This is needed for RFC 5780 support
# (STUN extension specs, NAT behavior discovery). The TURN Server
# supports RFC 5780 only if it is started with more than one
# listening IP address of the same family (IPv4 or IPv6).
# RFC 5780 is supported only by UDP protocol, other protocols
# are listening to that endpoint only for "symmetry".
#
# 选择UDP和TCP监听器监听端口;
# 默认(或者0)是表示监听的端口加1.
# 这是必须的，为了RFC 5780的支持(STUN的扩展规范, NAT后端的发现)。
# TURN服务器支持RFC 5780只有启动与多个监听同一族的IP地址(IPv4或IPv6).
# RFC 5780只有UDP协议,支持其他协议是监听"对称"型端口的。

# Listener IP address of relay server. Multiple listeners can be specified.
# If no IP(s) specified in the config file or in the command line options,

# Auxiliary STUN/TURN server listening endpoint.
# Aux servers have almost full TURN and STUN functionality.
# The (minor) limitations are:
# 1) Auxiliary servers do not have alternative ports and
# they do not support STUN RFC 5780 functionality (CHANGE REQUEST).
# 2) Auxiliary servers also are never returning ALTERNATIVE-SERVER reply.
# Valid formats are 1.2.3.4:5555 for IPv4 and [1:2::3:4]:5555 for IPv6.
# There may be multiple aux-server options, each will be used for listening
# to client requests.
#
# 辅助STUN/TURN服务器监听端口。
# 辅助服务器几乎有齐TURN和STUN功能
# (一些)局限性:
# 1) 辅助服务器没有替代的端口并且他们不支持STUN RFC 5780功能(变更请求)。
# 2) 辅助服务器也不会返回ALTERNATIVE-SERVER回复。
# 有效格式，IPv4的1.2.3.4:5555 和IPv6的[1:2::3:4]:5555。
# 可能会有多个aux-server选项,每个将用于监听客户端请求。

# (recommended for older Linuxes only)
# Automatically balance UDP traffic over auxiliary servers (if configured).
# The load balancing is using the ALTERNATE-SERVER mechanism.
# The TURN client must support 300 ALTERNATE-SERVER response for this
# functionality.
#
# (仅推荐老的Linuxes)
# 在辅助服务器自动均衡UDP流量(如果配置)。
# 使用ALTERNATE-SERVER的负载均衡机制。
# TURN客户端必须支持300个ALTERNATE-SERVER响应。

# Relay interface device for relay sockets (optional, Linux only).
# NOT RECOMMENDED.
#
# 终极接口设备为中继套接字(可选, 仅Linux).
# 不推荐。
#
#relay-device=eth1

# Relay address (the local IP address that will be used to relay the
# packets to the peer).
# Multiple relay addresses may be used.
# The same IP(s) can be used as both listening IP(s) and relay IP(s).
# If no relay IP(s) specified, then the turnserver will apply the default
# policy: it will decide itself which relay addresses to be used, and it
# will always be using the client socket IP address as the relay IP address
# of the TURN session (if the requested relay address family is the same
# as the family of the client socket).
#
# 中继地址(本地IP地址将用于传递数据包的给每个端)
# 可以使用多个中继地址。
# 相同的IP可以用作监听IP和继电器IP。
# 如果没有指定中继IP，那么turnserver将应用默认策略：它将自行决定使用那个中继
# 地址，并且它总是会使用客户端套接字的IP地址作为中继的IP地址在TURN会话中(如果
# 请求的中继地址族解决同族的客户端套接字)。

relay-ip=<IP>

# For Amazon EC2 users:#
# TURN Server public/private address mapping, if the server is behind NAT.
# In that situation, if a -X is used in form "-X <ip>" then that ip will be reported
# as relay IP address of all allocations. This scenario works only in a simple case
# when one single relay address is be used, and no RFC5780 functionality is required.
# That single relay address must be mapped by NAT to the 'external' IP.
# The "external-ip" value, if not empty, is returned in XOR-RELAYED-ADDRESS field.
# For that 'external' IP, NAT must forward ports directly (relayed port 12345
# must be always mapped to the same 'external' port 12345).
# In more complex case when more than one IP address is involved,
# that option must be used several times, each entry must
# have form "-X <public-ip/private-ip>", to map all involved addresses.
# RFC5780 NAT discovery STUN functionality will work correctly,
# if the addresses are mapped properly, even when the TURN server itself
# is behind A NAT.
# By default, this value is empty, and no address mapping is used.
#
# Amazon EC2用户:
# TURN服务器公开/私有的地址映射，假如服务器是在NAT后端。
# 在这种情况下,如果一个表单中"-X <ip>"使用一个-X，然后该ip将被作为中继ip地址来使用。
# 这种情况只适用于一个简单的例子,当一个中继的地址是被使用,和没有RFC5780功能是必需的。
# 单个中继地址必须通过NAT映射到外部的IP。
# 外部的IP值，假如不为空，通过XOR-RELAYED-ADDRESS字段返回。
# 外部的IP,NAT必须直接转发端口(转发端口12345，必须总是映射到相同的外部端口12345)。
# 在更复杂的情况下,当涉及到多个IP地址,这个选项必须使用几次,每个条目必须形
# 成"-X <public-ip/private-ip>",将所有涉及到的地址。
# RFC5780 NAT发现STUN功能正常工作，如果正确的地址映射,即使TURN服务器本身是
# 在一个NAT后。
# 默认，该值为空，并且没有使用地址映射。

# Number of relay threads to handle the established connections
# (in addition to authentication thread and the listener thread).
# If set to 0 then application runs relay process in a single thread,

# Uncomment to use long-term credential mechanism.
# By default no credentials mechanism is used (any user allowed).
# This option can be used with either flat file user database or

#
# 取消使用短期证书机制。
# 默认情况下不使用凭证机制(允许任何用户)。
# 短期证书机制必须使用PostgreSQL或MySQL或Redis数据库来存储用户密码。
#
#st-cred-mech

# This option is opposite to lt-cred-mech or st-cred-mech.
# (TURN Server with no-auth option allows anonymous access).
# If neither option is defined, and no users are defined,
# then no-auth is default. If at least one user is defined,
# in this file or in command line or in usersdb file, then
# lt-cred-mech is default.
#
# 这个选项是lt-cred-mech或st-cred-mech相反。
# (TURN服务器no-auth选项允许匿名访问)。
# 如果没有选项定义,没有用户定义,那么no-auth默认。
# 如果至少定义有一个用户,在这个文件中或在命令行或usersdb文件,
# 那么lt-cred-mech默认。
#
#no-auth

# TURN REST API flag.
# Flag that sets a special authorization option that is based upon authentication secret.
# This feature can be used with the long-term authentication mechanism, only.
# This feature purpose is to support "TURN Server REST API", see
# "TURN REST API" link in the project's page
# http://code.google.com/p/rfc5766-turn-server/.
# This option is used with timestamp:
# usercombo -> "timestamp:userid"
# turn user -> usercombo
# turn password -> base64(hmac(secret key, usercombo))
# This allows TURN credentials to be accounted for a specific user id.
# If you don't have a suitable id, the timestamp alone can be used.
# This option is just turning on secret-based authentication.
# The actual value of the secret is defined either by option static-auth-secret,
# or can be found in the turn_secret table in the database (see below).
#
# TURN REST API标志。
# 标志是设置一个特殊的授权选项,是基于身份验证的私密。
# 这个功能可以用于长期验证机制。
# 这个功能的目的是支持"TURN Server REST API",看到"TURN Server REST API"项目的页面的链接
# http://code.google.com/p/rfc5766-turn-server/。
# 这个选项是使用时间戳:
# usercombo -> "timestamp:userid"
# turn user -> usercombo
# turn password -> base64(hmac(secret key, usercombo))
# 这允许TURN凭证占用一个特定的用户id。
# 如果你没有一个合适的id,可以使用单独的时间戳。
# 这个选项只是打开基于私密的身份验证。
# 实际值定义的私密就是通过选择static-auth-secret,或可以在数据库中找到turn_secret表(见下文)。
#
#use-auth-secret

# 'Static' authentication secret value (a string) for TURN REST API only.
# If not set, then the turn server
# will try to use the 'dynamic' value in turn_secret table
# in user database (if present). The database-stored  value can be changed on-the-fly
# by a separate program, so this is why that other mode is 'dynamic'.
#
# TURN REST API的'Static'身份验证的私密值(字符串)
# 如果没有设置，那么turn服务器将尝试使用'dynamic'值在用户数据库的turn_secret表(如果存在)。
# 数据库存储的值可以随时改变，通过单独的程序，所以这就是'dynamic'模式。
#
#static-auth-secret     

# 'Static' user accounts for long term credentials mechanism, only.
# This option cannot be used with TURN REST API or with short-term credentials
# mechanism.
# 'Static' user accounts are NOT dynamically checked by the turnserver process,
# so that they can NOT be changed while the turnserver is running.
#
# 'Static'用户长期占凭证机制。
# 这个选项不能用于TURN REST API或短期凭证机制。
# 'Static'用户帐户不是turnserver程序动态检查,所以他们不能改变在turnserver运行时。
#
#user=username1:key1
#user=username2:key2
# OR:
#user=username1:password1
#user=username2:password2
#
# Keys must be generated by turnadmin utility. The key value depends
# on user name, realm, and password:
#
# 钥匙必须由turnadmin实用程序生成。键值取决于用户名称、领域和密码:
#
# Example:
# 例子,使用以下命令:
#
# $ turnadmin -k -u ninefingers -r north.gov -p youhavetoberealistic
#
# Output: 0xbc807ee29df3c9ffa736523fb2c4e8ee
# 输出是: 0xbc807ee29df3c9ffa736523fb2c4e8ee
#
# ('0x' in the beginning of the key is what differentiates the key from
# password. If it has 0x then it is a key, otherwise it is a password).
# ('0x'开始的关键是区分从密码的关键。如果它有0x,那么它是一个关键,否则这是一个密码)。
#
# The corresponding user account entry in the config file will be:
# 相应的配置文件中的用户帐户条目将:
#
#user=ninefingers:0xbc807ee29df3c9ffa736523fb2c4e8ee
# Or, equivalently, with open clear password (less secure):
#或者是这样，明文密码(不安全的):
#user=ninefingers:youhavetoberealistic
#
user=<yourname:yourpsw>

# 'Dynamic' user accounts database file name.
# Only users for long-term mechanism can be stored in a flat file,
# short-term mechanism will not work with option, the short-term
# mechanism required PostgreSQL or MySQL or Redis database.
# 'Dynamic' long-term user accounts are dynamically checked by the turnserver process,
# so that they can be changed while the turnserver is running.
# Default file name is turnuserdb.conf.
#
# 'Dynamic'用户帐户数据库文件名。
# 只有用户长期机制可以存储在一个文件,短期机制不会处理选项,短期机制需要PostgreSQL或MySQL或

# Option to set the "redirection" mode. The value of this option
# will be the address of the alternate server for UDP & TCP service in form of
# <ip>[:<port>]. The server will send this value in the attribute
# ALTERNATE-SERVER, with error 300, on ALLOCATE request, to the client.
# Client will receive only values with the same address family
# as the client network endpoint address family.
# See RFC 5389 and RFC 5766 for ALTERNATE-SERVER functionality description.
# The client must use the obtained value for subsequent TURN communications.
# If more than one --alternate-server options are provided, then the functionality
# can be more accurately described as "load-balancing" than a mere "redirection".
# If the port number is omitted, then the default port
# number 3478 for the UDP/TCP protocols will be used.
# Colon ( characters in IPv6 addresses may conflict with the syntax of
# the option. To alleviate this conflict, literal IPv6 addresses are enclosed
# in square brackets in such resource identifiers, for example:
# [2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 .
# Multiple alternate servers can be set. They will be used in the
# round-robin manner. All servers in the pool are considered of equal weight and
# the load will be distributed equally. For example, if we have 4 alternate servers,
# then each server will receive 25% of ALLOCATE requests. A alternate TURN server
# address can be used more than one time with the alternate-server option, so this
# can emulate "weighting" of the servers.
#
# 选项设置"redirection"模式。这个选项的值将备用服务器的地址UDP和TCP服务形式的<ip>[:<port>]。
# 服务器将发送这个值属性ALTERNATE-SERVER,错误300,在ALLOCATE请求,客户端。
# 客户端将只接收和自己相同的地址族的客户端的值。查看RFC 5389和RFC 5766为ALTERNATE-SERVER的功能描述。
# 客户端必须使用获得的值为随后的TURN通信。如果不止一个——alternate-server选项提供,那么功能可以更准确
# 地描述为"load-balancing",而不仅仅是一个"redirection"。如果端口号省略,那么为UDP/TCP协议，使用默认端
# 口号是3478。冒号(在IPv6地址字符可能与选项的语法冲突。缓解这种冲突,文字IPv6地址包含在方括号在这种
# 资源标识符,例如[2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478 。
# 可以设置多个备用服务器。他们将用于循环的方式。所有服务器池中被认为是平等的重量和载荷将平均分配的原则。
# 例如,如果我们有4个备用服务器,每个服务器将获得25%的分配请求。备用TURN服务器地址可以使用超过一次
# alternate-server选项,所以这可以效仿的"weighting"服务器。
#
# Examples:
#alternate-server=1.2.3.4:5678
#alternate-server=11.22.33.44:56789
#alternate-server=5.6.7.8
#alternate-server=[2001:db8:85a3:8d3:1319:8a2e:370:7348]:3478
              
# Option to set alternative server for TLS & DTLS services in form of
# <ip>:<port>. If the port number is omitted, then the default port
# number 5349 for the TLS/DTLS protocols will be used. See the previous

#
# 选项设置替代服务器TLS和DTLS服务形式的<ip>:<port>。
# 如果省略的端口号,那么默认端口号5349将使用TLS/DTLS协议。看到前面选择的功能描述。

# Option to allow or ban specific ip addresses or ranges of ip addresses.
# If an ip address is specified as both allowed and denied, then the ip address is
# considered to be allowed. This is useful when you wish to ban a range of ip
# addresses, except for a few specific ips within that range.
# This can be used when you do not want users of the turn server to be able to access
# machines reachable by the turn server, but would otherwise be unreachable from the
# internet (e.g. when the turn server is sitting behind a NAT)
#
# 选择允许或禁止特定的ip地址或ip地址范围。
# 如果指定一个ip地址允许和拒绝,那么ip地址被认为是允许的。这是有用的,当你希望禁止一个范
# 围的ip地址,除了一些特定的ip范围内。
# 这可以使用当你不希望turn服务器的用户能够访问机器通过turn服务器,但可能是另一方面从互联
# 网上不能到达(例如,当turn服务器是在一个NAT后)
