Neighbor entries tie the protocol address and the link-layer addresses under the same link. To delete an existing entry in the routing table, use the commands: ip route del ip route del default ip route del dev Display and Modify IP Neighbor Entries Or you can add a new route via gateway by typing: ip route add via Īlso, the command allows you to add a route for all addresses via the local gateway by adding the default option: ip route add default dev ip route add default via The interface name depends on the physical location. It’s been used on systemd-based Linux systems for some time. To add a new entry in the routing table that can be reached on a specific device, type in the command: ip route add dev The new naming scheme is referred to as the Predictable Network Interface naming. To view routing for a distinct network, use the following syntax: ip route list Modify IP Routing Table You can set the MTU (Maximum Transmission Unit) to improve network performance: ip link set mtu dev įind all the link command options by typing: ip link help The ip link command allows you to modify the transmit queue, speeding up or slowing down interfaces to reflect your needs and hardware possibilities. Both incoming and outgoing network connections are monitored. It is used to find out problems in the network and to analyze the traffic on the network. If you want to bring a network interface up (online), use the command: ip link set upĭisable an interface (offline) by entering: ip link set down Netstat is one of the famous tools that all Linux (though also used in windows) users heard of or used for once at least. To see a list of only the running interfaces use: ip link ls up Modify Network Interface Status
In case you need even more details, add another -s to the syntax: ip -s -s link ls NIS provides generic database access facilities that can be used to distribute, for example, information contained in the passwd and groups files to all hosts. You can also see similar information for an individual network interface with: ip -s link ls To see statistics for all network interfaces (details such as transferred or dropped packets, or even errors) use: ip -s link The NIS maps are created on the master NIS. If you want it to display the information for one specific device, type in the following: ip link show dev With NIS, an administrator creates information databases called maps from common UNIX (or Linux) system files.
INETWORK INFO LINUX DRIVER
To see link-layer information of all available devices (which have a driver loaded) use the command: ip link show
