我使用 apt 包管理器在 ubuntu 22.04.1 上安装了 danted，一切正常，直到我尝试连接它。
这是我的/etc/danted.conf
logoutput: /var/log/socks.log
internal: ens160 port = 110
external: ens160
clientmethod: none
socksmethod: username
user.privileged: root
user.notprivileged: nobody
client pass {

log: error connect disconnect
}
client block {
from: 0.0.0.0/0 to: 0.0.0.0/0
log: connect error
}
socks pass {
from: 0.0.0.0/0 to: 0.0.0.0/0
command: bind connect udpassociate
log: error connect disconnect
socksmethod: username
}
socks block {
from: 0.0.0.0/0 to: 0.0.0.0/0
log: connect error
}
这是systemctl status danted.service输出：

但是当我尝试运行 curl 时curl -x socks5://danteduser:<user pass>@<my server ip address>:110 google.com，我得到了这个：
curl: (97) Unable to receive initial SOCKS5 response.
journalctl -l | grep danted输出（最后一个systemctl restart danted）：

Sep 28 10:08:31 ubuntu20 systemd[1]: danted.service: Deactivated successfully.

显然端口 110 甚至没有打开，当我telnet <server ip> 110在本地机器上尝试时，我得到了这个：
Trying <server ip>...
telnet: Unable to connect to remote host: No route to host
这是/var/log/socks.log启动服务后的文件内容：

发送 curl 请求后，此文件中没有新日志！
