hi, i have a Linux (2.4.17) router connected to a traffic generator which does not continuously respond to ARPs from the linux router. The traffic generator only pumps large amounts of data (raw ip traffic) at a continuous rate. The generator only arps before and after the test is done, during the test the generator does not respond to ARPs. The Linux router performs ok till about few seconds and then fails very badly. Upon starting the traffic generator issue an arp request for the linux box.. I get an arp entry for that in my linux box. After few seconds I get an incomplete arp entry which does not timeout but after few minutes. I tried to increase the arp timeout value (altough default 60 sec should be good enough) to no avail. I cannot use a static arp entry for project specific reasons. Any ideas why is there an incomplete arp after only few seconds ? - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
