unable to use mii-tool command
I am using RHEL5 linux box and tried to check the network devices connected with my machine. So, I tried 'mii-tool' command, but got the below error:
[root@anthurium sbin]# mii-tool
SIOCGMIIPHY on 'eth0' failed: Operation not supported
no MII interfaces found
Could anybody please tell me what this error means and what is SIOCGMIIPHY ?? MOreover, how can I see network devicrs connected within my computer ?
