Using SNORT in Windows you can execute:
C:\Snort\bin> snort -W
This will provide a numbered list of interfaces similar to the image below:
On Linux, there is no -W option. How do you print a numbered list of interfaces in Linux? (I am not looking for answers about $ ifconfig -a)
You can run ip link show
.
$ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP qlen 1000
link/ether 02:00:17:02:40:5e brd ff:ff:ff:ff:ff:ff
