R2S-Lean不稳定

[pwrliang]

表现为使用一天半左右，无法上网，也无法进入ssh/管理页面，只能拔电源重启。 使用的软件：softether, ssr-plus和防火墙-端口转发.

很多人遇到同样的问题，而且ssrp还会跑流量，无论是v2ray还是trojan，现在用lienol版本没有出现这些问题

[stupidloud]

如果还在用带vssr版本固件的人，赶紧刷新版的吧

https://github.com/klever1988/nanopi-openwrt/blob/master/CHANGELOG.md#2020-03-10

vssr默认开启的socks服务器会让你的路由器变成公共代理，跑到死机的

[pwrliang]

@klever1988 您好，我跑的应该是10号以后的release，但是还是有死机的情况，估计不是开了socks代理的问题，我看了下ssr-plus里面的socks5代理是没有勾选的。

可以详细地说一下版本吗

[pwrliang]

@klever1988 版本为：R2S-Lean-2020-03-14-ROM.zip

[stupidloud]

@pwrliang 在之前的版本有死机现象吗？

[pwrliang]

@klever1988 之前的lean都会有，使用一天左右就会死机。您那里经过长时间的运行会复现这个问题吗？我用过别人编译的lean固件，自己也编译过，都会出现死机问题。

我不太确定到底是固件本身的问题，还是有安全漏洞被攻击。R2S作为了DMZ，但是ssh我设置了仅允许lan访问。 我用softether的桥接模式作为vpn连回家，然后ssrplus做代理，在防火墙设置开放一些端口给nas的plex和nginx使用，仅此而已。

[stupidloud]

我一半都是刷minimal长时间用，但最长也不超过三天，出现过断流，但是仅仅在我插拔usb无线网卡的时候，不过我和你最大的不同，我是光猫拨号，r2s当二级路由使用。 如果不分固件都会死机，那有没有可能是硬件？

至于肥版的固件，我都是release之后自己刷一下用半小时左右就刷掉了。刚才刷了17号的肥版，看负载没什么问题，我继续跑着观察看看吧。

[ostrichii]

我用lean的固件也遇到了，两三天就会出现死机，登录不上也上不了网，重启之后也看不到日志，不知道到底是啥原因导致。怀疑是fullconenat，关了跑一段时间看看

尝试关闭flow加速
