Thanks. could be a bad network switch. or a bad cable on that NIC. Though I wouldn't expect a bad cable to happen with such uniform periodicity (unless there's some physical disturbance that jiggles the cable every 4-5 seconds trigging an intermittent connection.) have you tried just walking around the back of that box and watching the little blinky lights on the back to see if they go OFF every 4-5 seconds for a second or so then come back on? I'd expect either a bad cable or switch to cause them to go off, if they really have disconnected. > > Dec 4 10:18:17 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:19 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:18:21 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:23 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:18:24 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:25 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:18:26 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:28 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:18:29 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:31 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:18:37 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:39 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:18:42 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:18:43 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:19:07 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:19:08 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:19:13 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:19:14 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:19:17 localhost kernel: e1000: eth1 NIC Link is Down > Dec 4 10:19:19 localhost kernel: e1000: eth1 NIC Link is Up 100 Mbps > Full Duplex, Flow Control: RX/TX > Dec 4 10:19:20 localhost kernel: e1000: eth1 NIC Link is Down -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- The Lord detests the way of the wicked but he loves those who pursue righteousness. ----------------------------- Proverbs 15:9 (niv) -----------------------------
