项目需要访问单点认证的网址 单点认证那边是没问题的,防火墙也是开的,其他地方没有做限制的了

# curl -v https://login.XXX.com/XXX/login -4
* About to connect() to login.jxcia.com port 443 (#0)
*   Trying 117.XX.XX.X...
* Connection refused
* Failed connect to login.XXX.com:443; Connection refused
* Closing connection 0
curl: (7) Failed connect to login.XXX.com:443; Connection refused

ip addr 输出了很多的虚拟网卡,有没有可能跟这个有关

看看路由和防火墙
twofox
2022-12-19 17:19:43 +08:00
@tomemi 防火墙全关,路由也不会有限制的

这里试了下,不加路径的二级域名是可以的。看返回头,隐藏了 nginx 版本,考虑是不是人家在服务器配置了 UA 检测?你改个浏览器的 UA 试试呢?

@twofox #2 抓包

telnet 看下端口通么。
twofox
2022-12-19 17:30:33 +08:00
@newaccount 单点服务也是我司的。。不会限制


@tomemi 有点为难我这个 CURD Boy 了
twofox
2022-12-19 17:33:18 +08:00
@aaa5838769 不通,就这一个地址不通,要是换成其他的域名。例如百度啥的,都是通的
cnit
2022-12-19 17:33:48 +08:00
你直接用 ip 加端口不走 nginx 试试
fengci
2022-12-19 17:34:41 +08:00
你是不是本地 hosts 了
Routeros
2022-12-19 17:35:03 +08:00
http_proxy?

# 拒绝 User-Agent
if ($http_user_agent ~* LWP::Simple|BBBike|wget|curl) {
return 444;
}
反正我们这有这个
twofox
2022-12-19 17:35:15 +08:00
@fengci 没有

@cnit 不行
cnit
2022-12-19 17:39:08 +08:00
你怕不是在命令行里面加了代理
twofox
2022-12-19 17:41:12 +08:00
@cnit 不可能的,系统会崩掉
motherfaka
2022-12-19 17:42:17 +08:00
telnet 不通,curl 其他网站通,大概率是服务端口的问题
cnit
2022-12-19 17:43:32 +08:00
额 我反正之前闹过这样的乌龙,其他的我想不到了 ,你可以试试在命令行里面能不能 curl google 或者 youtube 确认下
motherfaka
2022-12-19 17:45:35 +08:00
拿自己电脑测了一下,telnet 是通的,curl 也是通的,那还是客户端网络的问题……

refuse 不可能是 nginx 的功能
nginx 开始处理的时候都已经 accept 完毕了

1. 云厂商的防火墙
2. 域名备案

@lhbc 本地机房,备案完善
