下周我将举办一个局域网聚会，我们将创建一个没有互联网连接的独立局域网。由于我不想在 8 台计算机上设置静态 IP，所以我想在我的计算机上设置一个 DHCP 服务器。我发现有dhcp3-server。

问题可能是 DHCP 服务器会一直运行，当我在另一个网络中时，就会出现问题。我该如何设置它，以便在 LAN 聚会时启动它？

我使用带有 KDE 的 Kubuntu，如果这有什么区别的话。

好的，我已经安装了 dhcp 服务器，但它无法启动。我附上了一些命令、配置文件的输出

/etc/dhcp/dhcpd.conf

ddns-update-style none;
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet 192.168.100.0 netmask 255.255.255.0 {
  range 192.168.100.100 192.168.100.200;
}

答案1

dhcp3 服务器安装 ISC DHCP 服务器变体。

  • 启动后或者不需要时使用以下命令停止服务器：

    sudo 服务 isc-dhcp-server 停止
sudo 服务 isc-dhcp-server6 停止

  • 当你准备好参加派对时，先做以下准备：

    sudo 服务 isc-dhcp-服务器启动
sudo 服务 isc-dhcp-server6 启动

答案2

有很多选择，但最简单的方法是在聚会之前安装它，然后在连接到另一个网络之前将其卸载。
