This is recognized by the kernel as interface 'ep0'. I had the problem with my 4.2-BETA kernel, I found out last week. I cvsupped this morning, built a new kernel, and still have the problem. When I add an ip-address by hand with: ifconfig ep0 192.168.1.123 netmask 255.255.255.0 broadcast 192.168.1.255 it succeeds. I can connect to other machines. When I change the ip-address to something else like: ifconfig ep0 192.168.1.222 netmask 255........ then 'ifconfig' will show the new ip-address correctly. However, when connecting to other machines, or doing a ping, the interface will still think it has 192.168.1.123 as ip-address. So no networktraffic is possible for this interface: It, on one hand, thinks it is 192.168.1.222. While pinging to another machine, it will do an 192.168.1.123 icmp-request (which is answerd with an icmp-reply to 192.168.1.123). ep0 does not pick this up, since it thinks it is 192.168.1.222 An `ifconfig ep0 delete ` in between does not help either. When changing the ip-address by means of dhclient (Internet Software Consortium DHCP Client) there are no problems at all. The only way to get things right by hand is to remove the card from its slot and put it back in. In that way the interface will be gone completely. >How-To-Repeat: Just manually change the ip-address of ep0. >Fix: >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
