I'm seeing this happen on a 2.2.6-RELEASE system and on a system built from -stable as of noon today. I have de0 configured and working, at IP 206.112.106.11. If I try to add an alias IP address like this: ifconfig de0 inet 206.112.106.55 alias I get the message "ifconfig: ioctl (SIOCAIFADDR): File exists". (There is no other host using 206.112.106.55.) However, "ifconfig -a" shows the alias address (in addition to the original address) on de0, and pinging the alias address from another host is answered correctly by this host. However however, if from this host I try to ping 206.112.106.55 the ping fails 100% of the time. A little investigation with tcpdump shows that it sends an ARP who-is 206.112.106.55 but doesn't answer itself. The bogus "file exists" message doesn't bother me, but the odd ping-myself behavior has me a bit worried. Is this a bug, or do I need to go read the ifconfig man page again? *************************************************************************** * All opinions expressed herein fully | * * represent the views of my dogs: | Jim King * * Shortstop: "Bark!" | jim.king@mail.sstar.com * * Bunny: "Bark!" | http://www.sstar.com/jim_king/ * *************************************************************************** To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
