怪事:香港服务器 http reset

bin456789 4月前 37

vps 作为 http 客户端

访问某些网页(例如 google, qq, 1.1.1.1 )会出现 Connection reset

访问某些网页(例如 baidu )却正常

访问 https 网页,全都正常

求原因

具体:

http 访问 baidu,成功率 100%

curl -v http://www.baidu.com/
* About to connect() to www.baidu.com port 80 (#0)
*   Trying 103.235.46.39...
* Connected to www.baidu.com (103.235.46.39) port 80 (#0)
> GET / HTTP/1.1
> User-Agent: curl/7.29.0
> Host: www.baidu.com
> Accept: */*
>
< HTTP/1.1 200 OK

http 访问 google/qq/ 1.1.1.1,10 次大约有 1 次正常,其余 9 次 Connection reset by peer

curl -v http://1.1.1.1/
* About to connect() to 1.1.1.1 port 80 (#0)
*   Trying 1.1.1.1...
* Connected to 1.1.1.1 (1.1.1.1) port 80 (#0)
> GET / HTTP/1.1

> Host: 1.1.1.1
> Accept: */*
>
* Recv failure: Connection reset by peer
* Closing connection 0
curl: (56) Recv failure: Connection reset by peer

https 访问,全都正常
