xinetd 错误 service/protocol 组合不在 /etc/services 中

Xinetd error service/protocol combination not in /etc/services

尝试创建一个简单的 xinetd 风格的服务器,而不需要首先创建一个完整的服务。我有以下文件位于 /etc/xinetd.d/myscript:

service tester
{
        disable = no
        socket_type     = stream
        protocol        = tcp
        port            = 8087
        wait            = no
        user            = root
        server          = /root/prog
}

但是我在重新启动 xinetd 时不断收到以下错误: service/protocol combination not in /etc/services

解决方案是添加 type = UNLISTED,如下所示,并在 https://www.redhat.com/archives/fedora-legacy-list/2004-October/msg00146.html

中讨论
service tester
{
        disable = no
        socket_type     = stream
        protocol        = tcp
        port            = 8087
        wait            = no
        user            = root
        server          = /root/prog
        type            = UNLISTED
}
