Hi.
Kernel: 2.0 , Nettools: 1.3.6-BETA5
This is output of my job:
o68:~/tmp# arp -a Address HW type HW address Flags Mask ondraszek-gw.mak.polsl. 10Mbps Ethernet 00:C0:DF:49:9F:66 C * o68:~/tmp# host ondraszek-gw ondraszek-gw.mak.polsl.gliwice.pl has address 157.158.29.94 ondraszek-gw.mak.polsl.gliwice.pl has address 157.158.29.62 ondraszek-gw.mak.polsl.gliwice.pl has address 157.158.29.30 ondraszek-gw.mak.polsl.gliwice.pl has address 157.158.29.126 o68:~/tmp# ping ondraszek-gw PING ondraszek-gw.mak.polsl.gliwice.pl (157.158.29.94): 56 data bytes 64 bytes from 157.158.29.94: icmp_seq=0 ttl=64 time=2.6 ms

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.
