I've been flat out here -- but I've tried to stay on this thread .. Are you guys sure that this isn't the server end of the ip-over-dns software (nstxd) trying to get data back to the now non-existent client? It would have made it through your statefull kit if it was initiated from that problem address of yours (Paul), originally. The only thing I see not being consistent with the nstx stuff is the multiple sources/channels ... but that doesn't mean that there couldn't have been multiple connections from the problem address, or a multi-terminating version of the client/ server software .. (a dns hub of sorts). ----- Original Message -----

Same host, same src port, same types of packets, same ttl, same len) Whatever this is is obviously crafted from some sort of script. The only thing I can think of is recon. If someone has any bright ideas, speak up.I think Frank mentioned the packets being like 2048 in size, and this makes me wonder if it's a tad more then mere recon. Might be trying to exploit or develope an exploit for bind. and might be a tool in progress for a specific bind OS combo. But, I find just tossing the offenders into the "not allowed" list of entowrk addresses reduces the log fluff as well as hinder progressive testing, for them, at least off my networks.
