arping hangs for dhcp? #210

Closed kladkogex closed 7 years ago

kladkogex commented 7 years ago

if installed arping; then IPADDR=$(echo "$IPADDR" | cut -d/ -f1) ip netns exec "$NSPID" arping -c 1 -A -I "$CONTAINER_IFNAME" "$IPADDR" > /dev/null 2>&1 || true

Is this correct code in case $IPADDR=dhcp?

arping seems to hang in this case

jpetazzo commented 7 years ago

arping should send only one packet, and this is a gratuitous ARP packet so it shouldn't wait for a reply.

If you still see the problem, please re-open the issue and report the exact distro that you are using on the host!

Thank you.
