socks5 链接问题

socks5 链接问题

Closed this issue 7 years ago · 2 comments

测试发现在 socks5 代理下貌似有点小问题:

docker 在配置 lightsocks sokcs5 代理后进行 pull 镜像，会出现 pull 完成后出现 retry 动作，感觉像是最后校验失败
privoxy 将 lightsocks sokcs5 转换为 http 代理后，wget 走代理下载文件出现反复重试动作

curl 日志如下

对网络层不算太熟悉，但是感觉像是链接被提前关闭了

Answer 1 · 2017-10-27T11:35:08.000Z

请升级到 1.0.4
https://github.com/gwuhaolin/lightsocks/releases

Answer 2 · 2017-10-28T01:05:00.000Z

@gwuhaolin 升级到 1.0.4 后，问题并没有改善，貌似不是由于长时间下载超时关闭问题，因为实际下载时间并不长；感觉像是在最后下载完成后 server 端 buffer 没有被刷出去，导致 client 校验失败

复现过程

安装 privoxy，配置如下(forward-socks5 指向 lightsocks)

confdir /etc/privoxy
logdir /var/log/privoxy
actionsfile match-all.action # Actions that are applied to all sites and maybe overruled later on.
actionsfile default.action   # Main actions file
actionsfile user.action      # User customizations
filterfile default.filter
filterfile user.filter      # User customizations
logfile logfile
listen-address  0.0.0.0:8123
toggle  1
enable-remote-toggle  0
