The sysctl name is net.inet.icmp.quotelen. Next I'm going to make this more intelligent by always quoting the entire TCP header including TCP options if the original packet was TCP. This aids in-the-wild debugging a lot and allows the receiver to do more elaborate checks on the validity of the response. -- Andre
