well yeah I actually realized that and I meant ifconfig
anyway I executed both the commands in shell and the result is this :
linux:~ # sudo /sbin/ifconfig

Is it because I should install the drivers for my LAN card but openSuse seems to have installed the drivers for that .... and even if I connect from my cable modem to my PC directly ( and do not connect any router in between) there wont be any sign of internet connection so far .... I have also tried the procedures in the link below

as you can see in PIC no.1 the IP address and subnet mask is being shown but in my case only the name of my Ethernet card manufacturer is displayed .............thank you so much for your help ........
