select incorrect network interface on ubuntu 20.04.3
jakane opened this issue · comments
I have a lot of interfaces (mostly virtual) on my machine. I expect eno1 to be selected (that is the physical interface), however toptop selects a virtual interface (vethacf3bfc in this case).
I would really like to define an environment variable (tiptop_net) or command-line flag (--net) to force election of an interface.
$ cat /proc/net/dev

On mine it selects pxe0
You can now manually pick your interface with --net/-n.
