I am new to FreeBSD. I have been using NetBSD for about 9 years. I have FreeBSD v. 4.8 Release #1 running. Everything is smooth expect for one thing.
I can't traceroute to the box. I can do a traceroute -I to it, but not a regular traceroute, which tells me something about UDP, but I don't know where to look.
IS there a file somewhere that is closing certain UDP ports that respond to traceroute?
Apart from the usual suspect (firewall filtering out the incoming UDP and/or outgoing ICMP packets), what does
show? If it is _not_ 0 it means that UDP ports that are not in use don't generate a response, which implies that the normal 'traceroute' won't work. This feature is intended to make the life of (port scanning) hackers even more miserable than it must be already. There is a related variable for TCP as well (net.inet.tcp.blackhole).
