ipconfig and ifconfig
On Unix, you can obtain the machine's network configuration using ifconfig. The command on Windows is ipconfig. To summarize the command:
Use this tool to obtain the IP address, subnet mask, and default gateway.
On Windows, use
ipconfig /?for help.On Unix, use
man ifconfigfor help.Note that on Linux systems, you may not have permission to run ifconfig. It also may be in a location that isn't in your path—e.g., /sbin/ifconfig.
Here's a run of ifconfig on a Unix system:
$ /sbin/ifconfig -a
