Any other program attempting to generate packets using the raw protocol interface similarly bail out. Naturally, all other machines on the LAN are unaffected, and this appears to impact command line issued programs (there are no servers I've seen that employ SOCK_RAW). >How-To-Repeat: From a machine connected to the internet via PPPoE: - ifconfig tun0, get it's IP hping <ip of the tun0 interface> hping <ip of any host passing through tun0> nmap <ip of the tun0 interface> nmap <any host passing through tun0> >Fix: None known. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
