Linux xinetd 端口转发

xinetd 是一个功能强大的替代 inetd 的守护进程管理器，用于管理网络服务。它可以控制多个网络服务的启动和关闭，还可以配置服务的参数和限制对服务的访问。

安装

apt install xinetd

删除自带配置

rm -rf /etc/xinetd.d/*

新建ipv4转发

vim /etc/xinetd.d/tcp4-portmap 
service tcp4-portmap
{
    id = 1
    disable = no
    type = UNLISTED
    socket_type = stream
    protocol = tcp
    wait = no
    redirect = ipv6地址 443
    port = 443
    user = nobody
    flags = NODELAY KEEPALIVE NOLIBWRAP IPv4
    log_type = FILE /data/xinetd/tcp4-portmap.log
    cps = 100 30
}

新建ipv6转发

vim /etc/xinetd.d/tcp6-portmap 
service tcp6-portmap
{
    id = 2
    disable = no
    type = UNLISTED
    socket_type = stream
    protocol = tcp
    wait = no
    redirect = ipv4地址 443
    port = 443
    user = nobody
    flags = NODELAY KEEPALIVE NOLIBWRAP IPv6
    log_type = FILE /data/xinetd/tcp6-portmap.log
    cps = 100 30
}

启动转发

systemctl start xinetd.service
systemctl restart xinetd.service
systemctl status xinetd.service
