Ok.
What do you see if you enter this command?
ifconfig eth0 | grep HWaddr | awk '{print $5}'
Do you see your MAC ADDRESS?
Yes, I see the MAC ADDRESS
00:15:6D:AE:CC:00
if I try this command
ifconfig eth0 | grep HWaddr | awk -F : '{print $1$2$3$4$5$6}'
this is the result
eth0 Link encapEthernet HWaddr 00156DAECC
and this command
ifconfig eth0 | grep HWaddr | awk -F : '{print $1$2$3$4$5$6$7}'
this is the result
eth0 Link encapEthernet HWaddr 00156DAECC00
and this command
ifconfig eth0 | grep HWaddr | awk -F : '{print $3$4$5$6$7}'
this is the result
156DAECC00
is it the command will be
let NODE_ID=00$(echo $LAN_MAC| awk -F: '{print $3$4$5$6$7}')
