For example, if you set up a network appliance on your network, you’ll want to be able to call it by name immediately. This is part of the idea behind zero-configuration name service systems such as Multicast DNS (mDNS) and Simple Service Discovery Protocol (SSDP). If you want to fin...

如果你希望在每次开始vim时自动禁用搜索结果的高亮(但仍然允许通过命令手动高亮),可以考虑在你的vim配置文件(通常是~/.vimrc)中添加一行设置来清除高亮,但这样做并不会阻止高亮本身,而是每次搜索后需要你手动清除。 对于自动取消高亮的需求,一个简单的方法是在~/.vimrc文件中加入一段自动命令,每次搜索完成后自动取消...

On Broadcom switches, the ingress INPUT chain rules match layer 2 and layer 3 multicast packets before multicast packet replication has occurred; therefore, a DROP rule affects all copies. Rule Placement in Memory INPUT and ingress (FORWARD -i) rules occupy the same memory space. A rule counts...
