Question
A Linux computer has no access to the internet. Which command displays information about the network gateway for the system?
Options
- Atraceroute
- Bifconfig
- Cgateway
- Droute
- Eipconfig
Explanation
Displaying the default gateway on a Linux system requires a command that shows the kernel routing table. The route command prints this table, including the gateway entry.
Common mistakes.
- A. The traceroute command probes the network path to a remote host hop by hop and requires network connectivity to be useful; it does not simply display local gateway configuration.
- B. The ifconfig command displays interface configuration such as IP address, netmask, and MAC address, but does not show routing or gateway information.
- C. There is no standard Linux command called gateway; this is not a valid utility.
- E. The ipconfig command is a Windows utility, not a Linux command, and is not available on a standard Linux system.
