This is by no means an answer to your question, but I thougt I'd mention it any way. You should not use 12.12.12.12 as address on a local network that is connected to the internet. There already exists a network with this range of adresses : bash-2.05$ traceroute 12.12.12.12 [...snip...] 19 ar2-a3120s4.sffca.ip.att.net (12.127.1.145) 175.786 ms 171.715 ms 174.116 ms 20 12.127.194.102 (12.127.194.102) 218.748 ms 221.557 ms 221.263 ms 21 * * 12.127.194.102 (12.127.194.102) 217.661 ms !H 22 * 12.127.194.102 (12.127.194.102) 219.382 ms !H * 23 12.127.194.102 (12.127.194.102) 219.218 ms !H^C If you continue to use these adresses on your local network, you will never be able to view any internet site hosted on any part of the REAL 12.12.12 network. RFC1918 states a list of free blocks for use in private/local networks (read it here : http://www.rfc.net/rfc1918.html) This part of the RFC is the actual interrestig thing : 10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix) So use 192.168.somenumber.0/24 for your local LAN, is stead of 12.12.12.0/24... > ping: sendto: No buffer space available > ping: sendto: No buffer space available But this probably won't fix your buffer space problems :) -- grtz, Daan Vreeken - PA4DAN - Danovitsch@Danovitsch.dnsq.org Control the lights in my room: http://www.Danovitsch.dnsq.org/webcam To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
