The most likely problem is that (even as root) your PATH is not set to include the directory where these utilities are found. You don't say which distribution you are using, but common places to look for these are /sbin, /usr/sbin, or /usr/local/sbin. I recommend that you find if the utilities are actually installed on your system. If you have rpm, you can use it to find out; otherwise, try Once you know where these programs are, you can set your shell PATH variable to include those directories in the search path.

All these utilities come with net-tools package check if it is not installed.

$ rpm -q net-tools

If not download on install the rpm
