The hardware didn't change. I installed 4.0-RELEASE over the Internet and the problem started. (I no longer have the 3.4-RELEASE available for comparison.) After boot, the machine will not talk to, or see the 10base-2 lan. Pings return Host is down, tcpdump returns nothing. A 3.4-RELEASE machine on the same segment shows activity when tcpdump is issued. If you ping the 4.0-RELEASE machine, pings return host is down. I don't know if it makes a difference or not but xl0 also has isc-dhcpd bound to it. This gateway is also the dhcp server for the segment attached to the xl0 nic. >How-To-Repeat: Set the nic to automatic configuration. (I don't have the exact words but it is supposed to automatically determine the media type.) In rc.conf: ifconfig_xl0="inet 192.168.0.1 media autoselect netmask 255.255.255.224" Boot the machine. ifconfig xl0 returns: xl0: flags=8843<up,broadcast,running,simplex,multicast> mtu 1500 inet 192.168.0.1 netmask 0xffffffe0 broadcast 192.168.0.31 ether: 00:50:04:6c:bf:21 media: autoselect(none) status: no carrier Ping 192.168.0.6 Ping: sendto: host is down Enter ifconfig xl0 media 10base2/BNC Ping 192.168.0.6 Ping works >Fix: When the boot is complete, signon as root and enter: ifconfg xl0 media 10base2/BNC. At this point, the machine works normally. This is the only repeatable way I have found to get around the problem. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
