I'm running mail services (exim, fetchmail, popper) on FreeBSD 4.5 In a session trying to track down a problem related to a bad cable, I found that tcpdump -i xl0 -v -v -v host pop.incentre.net
has lots of lines like this: 20:20:11.166767 postie.sjsa.internal.net.1126 > bach.ccinet.ab.ca.pop3: F [bad tcp cksum 4f5e!] 61:61(0) ack 2075 win 33304 <nop,nop,timestamp 3005321 3937592> (DF) (ttl 64, id 57145, len 52, bad cksum 0!) But netstat -I xl0 -w 10 during the same interval when the above were coming down at 5-10 per second showed: input (xl0) output packets errs bytes packets errs bytes colls 32 0 4019 28 0 4573 0 24 0 3512 22 0 4934 0 444 0 30070 433 0 227132 0 Explanations? (I also get them on the local network; it's not just this destination host.) -- Sherwood Botsford St. John's School of Alberta _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
