** Description changed: Binary package hint: iputils-arping + + This bug prevents the arping utility from iputils-arping from detecting + any host as online due to the broadcast ARP requests being sent to an + invalid address. There is currently no feasable work-around for the + users, as the iputils-arping package is required by network-manager and + so installing the arping package would break network managers + dependencies. + + This is a regression in Ubuntu 10.10 from Ubuntu 10.04. + + TEST CASE: arping any online and reachable host in the local subnet, that is not currently in the arp cache. You should receive arp replies. + TEST CASE: arp -d IP; arping -b IP + + This bug has been fixed upstream in [1] and in Natty + (3:20100418-3ubuntu1).
