Please update your config.json file on server side after upgrading shadowsocks-libev to 3.2.0

[iROCKBUNNY]

Well, ironically, this is not a ShadowsocksX-NG issue, but it is a critical one! So I opened this issue to provide a simple work-around on Ubuntu 16.04 LTS.

After upgrading shadowsocks-libev to 3.2.0 on your server side, you might as well update your config.json file.

On Ubuntu 16.04 LTS, it is usually located at /etc/shadowsocks-libev/config.json. If you have a previous version installed, like 3.1.3, the config.json file would not update, thus causing your shadowsocks-libev connection invalid argument errors.

The work-around is simple, just replace your config.json file as folllows:

{
    "server": "your.server.i.p",
    "server_port": port_number_like_8388,
    "local_port": 1080,
    "password": "some_password_nobody_knows",
    "timeout": 60,
    "method": "chacha20-ietf-poly1305"
}

Good luck!

My server config file is always in this format. What is the wrong format?

[iROCKBUNNY]

@qiuyuzhou It came with an additional local key in the json dict, in the 3.1.3 release.

[qiuyuzhou]

Do you mean local_port is a required key?

[iROCKBUNNY]

It looks like this in the 3.1.3 configuration file.

{
    "server": "your.server.i.p",
    "server_port": port_number_like_8388,
    "local": "your.local.i.p",
    "local_port": 1080,
    "password": "some_password_nobody_knows",
    "timeout": 300,
    "method": "chacha20-ietf-poly1305",
    "fast_open": false
}

[qiuyuzhou]

You mean remove the local key-value in config then it is work?

[iROCKBUNNY]

@qiuyuzhou as well as the fast_open key.

}

but it not work

[tkizm1]

now mac --fast-open make sense?

[qiuyuzhou]

@tkisme As I known, --fast-open is depend on the feature of linux kernel.

[qiuyuzhou]

@zhouxl Please try without plugin first.

[zhouxl]

@qiuyuzhou I need the plugin, I notice in 1.8.0 will install plugin，when release it.
