在linux环境下使用UDP的command无法处理命令

[x0gundam1133]

在linux环境下使用UDP 的commond 无法处理命令
版本2.0.1
.net 8.0.21
系统Ubuntu / linux容器
同一套代码同一个命令，在window环境正常，在linux环境有udp连接log，但没有命令处理log

build.AddServer<StringPackageInfo, CommandLinePipelineFilter>(
                    builder =>
                    {
                        builder                         
                         .UseCommand((commandOptions) =>
                         {
                             commandOptions.AddCommandAssembly(this.GetType().Assembly);
                         })
                        .UseSession<CmdSession>()
                        .UseUdp();
                    }
                    );

public class ServerCmd : ICommand<CmdSession, StringPackageInfo>
{
    public void Execute(CmdSession session, StringPackageInfo package)
    {
        if (string.IsNullOrEmpty(package.Body))
            return;

        session.Logger.LogInformation("run cmd: " + package.Body);       
    }
}

public class CmdSession : AppSession
{

}

It is unit test about this feature:
https://github.com/kerryjiang/SuperSocket/blob/f15e45e3c4e4918d5e595cbd25df6543bd7e02e6/test/SuperSocket.Tests/CommandTest.cs#L262C9-L322C10

Check the debug logs to see if the command is discovered.

重点在于命令同时要使用UDP

@kerryjiang 使用测试代码如下

static async Task Main(string[] args)
{
    using (var server = MultipleServerHostBuilder.Create(args)
            .AddServer<StringPackageInfo, CommandLinePipelineFilter>(
            builder =>
            {
                builder
                 .UseCommand((commandOptions) =>
                 {
                     commandOptions.AddCommand<ServerCmd>();
                 })
                .UseSession<AppSession>()
                .UseUdp();
            }).BuildAsServer())
    {
        await server.StartAsync();
        var endpoint = new  IPEndPoint(IPAddress.Parse("127.0.0.1"), server.Options.Listeners[0].Port);

        using (var client = new UdpClient())
        {
            var buffer = Encoding.UTF8.GetBytes("ServerCmd cmd reloadcfg cfgid 1" + Environment.NewLine);
            await client.SendAsync(buffer, buffer.Length, endpoint);
        }
        Console.ReadLine();

        await server.StopAsync();
    }
    Console.ReadLine();
} 

public class ServerCmd : ICommand<AppSession, StringPackageInfo>
{
    public void Execute(AppSession session, StringPackageInfo package)
    {
        if (string.IsNullOrEmpty(package.Body))
            return;

        session.Logger.LogInformation("ServerCmd: " + package.Body);
    }
} 

确实在linux下UDP无法接收cmd数据
test@test-Virtual-Machine:~/udp_server$ dotnet udp_server.dll
warn: UdpConnectionFactory[0]
Failed to set socket option SIO_UDP_CONNRESET because the platform doesn't support it.

在windows环境测试正常

[x0gundam1133]

找到问题了··· 可以了
var buffer = Encoding.UTF8.GetBytes("ServerCmd cmd reloadcfg cfgid 1\r\n");
命令必须\r\n结尾 ，在linux环境下Environment.NewLine 的返回不对
