我在将 debian jessie 配置为 noip.com 更新程序时遇到问题。我的配置如下所示：
# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
use=web
web=checkip.dyndns.com
web-skip='Current IP Address: '
protocol=dyndns2
server=dynupdate.no-ip.com/nic/update
login=myusername
password='mypass'
myhost.noip.me
一切似乎都很好，但如果我 ping myhost.noip.me，IP 地址不会更新。通过检查
ddclient -daemon=0 -debug -verbose -noquiet 2 /etc/ddclient.conf
我得到以下回复：

我认为我当前的（人工）IP“12.34.56.78”已正确设置。现在，如果我 ping（我的人工主机）myhost.noip.me，我会得到一个不同的 IP。
有什么建议我需要更改什么才能让 ddclient 与 noip.com 一起使用吗？
答案1
您显示的跟踪显示ddclient轮询checkip.dyndns.com了您机器的 IP，发现 IP 没有更改，因此决定跳过联系dynupdate.no-ip.com更改IP。如果它已联系dynupdate.no-ip.com，您将在跟踪中看到类似这样的行
CONNECT: dynupdate.no-ip.com
后面会跟着一堆SENDING和RECEIVE行。
我发现，如果您想强制ddclient执行整个操作，您应该使用 停止任何当前正在运行的守护进程，sudo service ddclient stop并使用 删除其缓存文件sudo rm /var/cache/ddclient/ddclient.cache。然后任何后续运行都必须执行所有检查。
另外，你的配置文件是错误的。您不应该/nic/update在server设置中，因为这是设置的一部分protocol。 （使用dyndns2协议意味着/nic/update附加。）作为参考，我当前的配置是：
use=cmd
cmd='dig +short myip.opendns.com @resolver1.opendns.com'
protocol=dyndns2
ssl=yes
server=dynupdate.no-ip.com
login=<YOUR LOGIN>
password=<YOUR PASSWORD>
<YOUR HOST>
我使用该dig命令来获取我的公共 IP，而不是通过 HTTP 联系服务器。
答案2
protocol=noip
我正在使用 noip，但使用 noip 协议，就像它在 --help 标志内一样，请查看此帮助以获取更多信息。
答案3
您的配置唯一的问题是服务器更新地址。它应该是：
# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
use=web
web=checkip.dyndns.com
web-skip='Current IP Address: '
protocol=dyndns2
server=dynupdate.no-ip.com
login=myusername
password='mypass'
myhost.noip.me
您可以通过执行以下命令来测试配置：
sudo ddclient -verbose -foreground
您应该看到路由器部分（使用“网络”提供商提取 IP 地址），然后使用 no-ip 进行身份验证并更新 IP 地址：
ONNECT: checkip.dyndns.com
CONNECTED: using HTTP
SENDING: GET / HTTP/1.0
SENDING: Host: checkip.dyndns.com
SENDING: User-Agent: ddclient/3.8.3

答案4
protocol=dyndns2
use=web, if=eth0
server=dynupdate.no-ip.com
[email protected]
password='mysuperpassword'
myhost.no-ip.org
你有“if = ppp0”。您使用“拨号”连接吗？我的有“if=eth0”，因为 dsl ppp 在调制解调器/路由器上。
Your ping test is on the same network, or you try on a different (outside) computer? Could be a local DNS issue.
