回复了 ssbg2 创建的主题 MacBook Pro 需要买个能装 MBP16 和一机两镜的双肩包,谁给推荐下?
@coolmint @stimw 嗯,谢谢了,我去问问身边有没有人用这个。至于重不重的,反正我就那么一会,比起重,热可能更让人担心一些,偏偏我还比较喜欢用 70200,要么就是索性电脑不背了,放单位,平常背着之前的单肩包通勤,包里装个 70200 装个 35 的标头。家里那个 15.6 的 mbp 拿起来再用,如果有必要的话……

@discrete 样子是漂亮,就是我同事那个隔断起毛让吐槽了蛮久,感觉两千多有点不匹配。
@israinbow https://www.bilibili.com/video/BV1mM4y1u7Pq 注意看 1 分 40 秒开始,正式版要是这玩意也砍了那只能说 MS 实在是超出了我想象的脑残。
@stimw 嗯,这是个可能。我再去搜搜相关信息,看看外网上有没有人提这个问题,谢谢了。

@mxT52CRuqR6o5 谢谢,我再去搜搜看。
@yimity 为啥是用户的错?

@mxT52CRuqR6o5 没有,就一个,我甚至都没有换过线。
@doveyoung 嗯,顺着您的思路,我查看了下 mtu 和相关的设置,都是正常的,包括使用 netstat -s |grep reject 查看了下,发现因为时间戳拒绝的包很多。
最终发现了问题的原因:之前这个 nginx 服务器上多绑定了一个 18 段的 IP,然后更改了网络环境后,这个网卡的配置却一直没有被删除,所以就是您说的 nginx 服务器找不到正确的路径回复给客户端,导致了握手失败。
删除这个 ip 配置后,一切正常了。
谢谢您了!
@doveyoung 嗯,谢谢了,我再想想看。
@NUT 谢谢您,我测试了,是通的。

@doveyoung
谢谢您,1 、虚拟机上用 curl -v,结果就是
Trying xxx.xxx.xxx.xxx:443 ....
TCP_NODELAY SET
然后等一会就超时了,提示 Closing connection 0……

2 和 3 、客户端虚拟机上( 18.200 )使用 curl 发送 get 请求,输出情况是这样:
tcpdump -n port 443 -i ens192 and host 192.168.16.218 -vv

以上都是用域名请求的,客户端能解析到实际的内网 IP 且服务端能监听到请求,我认为网络层是通的,现在就是没有发送到 nginx 里。

使用 curl 对 IP 请求是这样请求的: https://IP:port/assets,可以正常得到返回信息。
另外就是 /proc/sys/net/ipv4/tcp_tw_recycle 这个值是 0
嗯,谢谢大家,我这会再去试试看。
@fangMu 试过了,不行

@seers 也不行,只要关闭 ssl on,就无法成功握手了。
@jjeyz 看 access_log 是这样:
