What kind of packets? How are you generating them? What software are you using? What kernel version are you using? Are you *SURE* you're sending 1000? What have you already tried? Then try to break down the problem, narrow down the possible causes. For example: stick a (known to be reliable) switch between the two machines and have it tell you how many packets it sees. That'll at least let you know if you're losing packets on the sending or the receiving side. Regards, Kristof
