SIOCSARP: No such device
Ondraszek-gw is my router, i am on subnet 3 ( netmask 255.255.255.224 ),
m,y gateway is 157.158.29.94.
The question is why arp does not work. It isnt just add entry: every
attempt to write to arp cache ends with this message.
I dont need this on my computer, but on router it is pretty good thing: I
can make users not to change theirs IP numbers in subnet.
TIA,
