Craig Reading craig.reading1 at gmail.comAll, I am 99% certain this is a problem with the USB 2.0 to 10/100/1000 Gigabit Ethernet LAN Wired Network Adapter I added to my OpenBTS server to solve another issue. Having looked through the source code and compared good and bad wireshark traces I can find no difference or bug in the ARP handling. Hence, time to move on and build up a new dedicated server for OpenBTS based on Ubuntu 12.04.
