Ok before you guys say upgrade, here's the scoop. 2.2.5-Stable running as a news server with full feed on a T1 line. After 80 days, the interface (ep0) went down, ifconfig ep0 down; ifconfig ep0 up broght the system back to life. Again at 112 days, same thing. I rebooted it just incase. Here's netstat -s output, notice the strange negative numbers. Could the counters wrapping cause the interface to go offline? ip: 160041838 total packets received 0 bad header checksums 0 with size smaller than minimum 0 with data size < data length 0 with header length < data size 0 with data length < header length 0 with bad options 0 with incorrect version number 0 fragments received 0 fragments dropped (dup or out of space) 0 fragments dropped after timeout 0 packets reassembled ok 160041797 packets for this host 30 packets for unknown/unsupported protocol 0 packets forwarded 11 packets not forwardable 0 redirects sent 124960549 packets sent from this host 9 packets sent with fabricated ip header 0 output packets dropped due to no bufs, etc. 0 output packets discarded due to no route 0 output datagrams fragmented 0 fragments created 0 datagrams that can't be fragmented icmp: 3963 calls to icmp_error 0 errors not generated 'cuz old message was icmp Output histogram: echo reply: 127 destination unreachable: 3963 0 messages with bad code fields 0 messages < minimum length 0 bad checksums 0 messages with bad length Input histogram: echo reply: 12 destination unreachable: 1775 source quench: 39 routing redirect: 108079 echo: 127 time exceeded: 4847 address mask request: 4 127 message responses generated igmp: 30 messages received 0 messages received with too few bytes 0 messages received with bad checksum 0 membership queries received 0 membership queries received with invalid field(s) 20 membership reports received 0 membership reports received with invalid field(s) 20 membership reports received for groups to which we belong 2 membership reports sent tcp: 124568601 packets sent 49925081 data packets (-1164652352 bytes) 3261982 data packets (1959566876 bytes) retransmitted 32 resends initiated by MTU discovery 49620214 ack-only packets (47810782 delayed) 8 URG only packets 1123589 window probe packets 20396951 window update packets 242964 control packets 159096534 packets received 46086543 acks (for -434530479 bytes) 6439546 duplicate acks 0 acks for unsent data 103126413 packets (-714293104 bytes) received in-sequence 3269043 completely duplicate packets (-2080469512 bytes) 221 old duplicate packets 4879525 packets with some dup. data (-1247669438 bytes duped) 196570 out-of-order packets (79007733 bytes) 806 packets (771 bytes) of data after window 771 window probes 7855568 window update packets 11849 packets received after close 108 discarded for bad checksums 0 discarded for bad header offset fields 0 discarded because packet too short 115014 connection requests 110979 connection accepts 3018 bad connection attempts 692 listen queue overflows 214518 connections established (including accepts) 272037 connections closed (including 36784 drops) 66208 connections updated cached RTT on close 66208 connections updated cached RTT variance on close 52838 connections updated cached ssthresh on close 3438 embryonic connections dropped 40673991 segments updated rtt (of 41011229 attempts) 2020595 retransmit timeouts 535 connections dropped by rexmit timeout 1704217 persist timeouts 42 connections dropped by persist timeout 6510 keepalive timeouts 2922 keepalive probes sent 2946 connections dropped by keepalive 5101871 correct ACK header predictions 87888605 correct data packet header predictions udp: 830380 datagrams received 0 with incomplete header 0 with bad data length field 0 with bad checksum 3963 dropped due to no socket 0 broadcast/multicast datagrams dropped due to no socket 0 dropped due to full socket buffers 0 not for hashed pcb 826417 delivered 359131 datagrams output Andrew Webster andrew@pubnix.net Key fingerprint = CF E8 16 B8 A6 DB E3 C9 83 E7 96 24 25 58 15 6E PubNIX Montreal Connected to the world Branche au monde P.O.
