I hope this is the correct list to post to, if not, I apologize. I've had an ongoing problem with arplookup for some months now and as of yet, haven't been able to find anything on the web concerning my particular problem. Every 24 hours, almost to the minute, I get the following errors; *Note This proceeds each arplookup failure em0: Link is Down em0: Link is up 100 Mbps Full Duplex Sep 25 01:32:49 thisbox kernel: arplookup 169.0.0.1 failed: host is not on local network Sep 25 01:33:05 thisbox kernel: arplookup 10.32.240.171 failed: host is not on local network Sep 26 01:23:37 thisbox kernel: arplookup 169.0.0.1 failed: host is not on local network Sep 26 01:23:49 thisbox kernel: arplookup 10.32.240.171 failed: host is not on local network Sep 27 01:23:35 thisbox kernel: arplookup 169.0.0.1 failed: host is not on local network Sep 27 01:23:48 thisbox kernel: arplookup 10.32.240.171 failed: host is not on local network When this happens, one by one, each of my (ssh, gaim, irc, etc.) connections time out until every connection is dead. I'm using RoadRunner Business Class with a static IP on em0 and an internal subnet 172.16.XXX.XXX on em1. I was getting the errors on two older nics I had, so I bought new nics in hopes that would correct the problem. I was running FreeBSD 5.4-Release p7 and switched to FreeBSD 5.4-STABLE about a week ago. I'm running the most current DHCP server, IPFW2, and NATD. I have the following in /etc/sysctl.conf kern.polling.enable=1 net.inet.tcp.syncookies=0 net.inet.udp.blackhole=1 net.inet.tcp.blackhole=2 # TCP send and receive spaces net.inet.tcp.sendspace=1048576 net.inet.tcp.recvspace=1048576 # Socket queue defense against SYN attacks kern.ipc.somaxconn=1024 # Redirects net.inet.icmp.drop_redirect=1 net.inet.icmp.log_redirect=1 net.inet.ip.redirect=0 # Subnet net.link.ether.bridge_cfg=em0,em1 net.link.ether.bridge.enable=0 net.link.ether.bridge.ipfw=0 net.link.ether.ipfw=1 # ARP cleanup net.link.ether.inet.max_age=1200 # Source routing net.inet.ip.sourceroute=0 net.inet.ip.accept_sourceroute=0 # Broadcast ECHO response net.inet.icmp.bmcastecho=0 # Other broadcast probes net.inet.icmp.maskrepl=0 net.inet.ip.fw.dyn_ack_lifetime=3600 net.inet.ip.fw.dyn_buckets=1024 net.inet.ip.fw.one_pass=0 I have the following in my kernel conf; # Firewall Stuff options IPFIREWALL_DEFAULT_TO_ACCEPT options IPFIREWALL options IPFIREWALL_FORWARD options IPFIREWALL_FORWARD_EXTENDED options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=10 options IPDIVERT options DUMMYNET options BRIDGE options IPSTEALTH options HZ=1000 options DEVICE_POLLING It is probably a bad idea to post my /etc/rc.conf ifconfig info here, but since I'm almost positive that in order for someone to help me track this down, they're going to want/need to know what is in there, I'll wait in hopes of a response first.
