Dear Friends ,
One of My linux server , I have 4 NIC card . I plugged a network cable one of NIC card . Now How can I understand which interface (eth0 or eth1 or eth2 or eth3) is connected with the cable ?
Which command I need to use to find it ?
My second question is :
using 'ethtool ' output I got a line : "Link detected : yes"
what does it means ?
