Administrivia and future plans network wise

I have added ratelimiting to io.solarscale.de which runs nsd. For this the nsd needed a recompile. This literature on the web was very helpful: nsd-ratelimit. I have set it to 12 queries per second, same as wildcarddnsd's ratelimit on americas.centroid.eu.

I have evaluated a lot of scenarios on how I want to reorganize my network and I have decided to get a DSL with static IP's in February 2015 again. I'll be running a wildcarddnsd from home again. Earlier in september 2014 my vps moon.virgostar.net will expire, I'll take it out of active DNS duty possibly in august. I'll run with 2 nameservers from that point on until 2015. In february I'm also going to get rid of the io.solarscale.de vps possibly for a transip.eu (amsterdam) vps instead (which will run OpenBSD). This is still in the clouds (so to speak) so I'm not entirely positive on that.

And to test the transip.eu vps I'll possibly get that in november 2014 possibly after the Wildcarddnsd 0.9.0 BETA release. So a lot of shuffling is taking place, the only thing that won't change is americas.centroid.eu which is prepaid until 2016, unless they figure out how to hypervisor OpenBSD in bhyve, which I will then probably take.

Wildcarddnsd now has packet rate limiting

I don't think I've ever had someone use me for an amplification DoS attack, but I don't watch the logs all the time. However it's not impossible so I have added a rate limiting algorithm on the hash of the IP querying my server so that I will drop the query when a threshold is reached. I had given this implementation thought for a while now and finally I wrote out the code. Wildcarddnsd will use more memory depending on the packets per second (details) and the hash of IP addresses is limited to 16 bit, meaning that there can be collisions between unrelated IP addresses that cause the ratelimiting to snare. But a high enough rate limit of say 12 packets per second on a nameserver with a usual TTL of 1 day shouldn't cause a problem. The pps is definable between 1 packet per second and 127 packets per second. The maximum setting will consume up to 120 MB of RAM, but RAM is cheap when we talk about 120 MB's. :-) I'm pretty happy right now.

Got OpenBSD 5.5 in the mail yesterday

I got my pre-ordered OpenBSD CD's in the mail. Unfortunately the seal was broken so someone possibly tried these out. Also I already upgraded my entire network to 5.5 on May 1st. Let this be a warning to OpenBSD, release pre-orders early or be faced with us doing ftp installs! We can't wait we're that hooked! However the CD's are quality like always, it's just too bad these become cup coasters after half a year, but that's part of the product that someone should know about.

Two "racing" ARP's

OpenBSD is different than other OS's in that it has a reverse ARP channel open alongside a forward ARP channel. I tried to exploit this with one of my programs I wrote, since frames are in sequence and scheduling in the OpenBSD kernel is done in a FIFO manner.

These are net-games but this can be used to test the network stack load on an OpenBSD host/router to look for how much usage it gets. That in itself isn't an exploitation though.

The highest possible date on OpenBSD 5.5

Look...

mercury$ date -r 67768036191673199            
Wed Dec 31 23:59:59 CET 2147485547
mercury$ date -r 67768036191673200            
date: conversion error

What's interesting is that localtime() will fail here at just under 2^55 bits. I wonder if we can take it all the way up to 2^63 bits.

Mercury (Computer) OpenBSD dmesg

I paniced a little last night. OpenBSD in -current out of the box with no patches isn't ready for it yet. Luckily an OpenBSD developer helped me with patches that made the wd0 drive (in IDE mode) work. Here then is a patched dmesg:

SPF support in wildcarddnsd

Happy Easter! I have programmed SPF support into wildcarddnsd just now. I hope I won't be leaving any easter eggs behind but if I do it's possibly pasted from the TXT functions, since SPF is TXT with a different RR# (99). I'll be moving this into production any time now.
