I needed to put an alias on lo0 for 127.0.0.2 and I made the mistake of assuming this would work like any other interface but that isn't the case. ifconfig inet lo0 127.0.0.2 netmask 255.255.255.255 alias results in an ip that I can ping but when I startup dnscache and ask it to listen on that ip it won't respond to queries. ( Yes queries from the same host ) If I switch the netmask to 255.0.0.0 ( which goes completely against the man page for ifconfig ) and everything works great. Also /etc/defaults/rc.conf shows... #ifconfig_lo0_alias0="inet 127.0.0.254 netmask 0xffffffff" # Sample alias entry. If I follow that sample ( note the netmask ) things won't work right. Am I missing something or is lo0 treated differently for some reason? FreeBSD 4.5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
