Countrary to other hosts, it does send DHCPDISCOVER even though it does have earlier assigned IP. In that same situation others send DHCPREQUEST.... e.g that client sends DHCPDISCOVER despite the fact, that its "ethX" does have "some" address.... and will respond to ICMP ping. So my conclusion for dhcpd would be not to differenciate (much) server side processing of received DHCPDISCOVER from received DHCPREQUEST. Regarding "low priority", pls notice, that these days people don't use "long-term / human attended" connection services like ssh. One does not notice the problem while using only IMAP or HTTP. -R W dniu 03.07.2014 22:17, Shawn Routhier via RT pisze: > There is an issue about what we should do in this case I just need > to figure out what will work and be consistent with the specs.
