For about 420.- CHF you will get a little box capable with 4 sensors which are accesable via SNMP. If you need more than that, you will ether need a serious appliance or do it yourself. If you decide to DIY, RS232 is your friend. With solutions like this: http://www.phanderson.com/ you could monitor almost unlimited number of temperature and humidity positions but BE CAREFUL with the bus length, we have run into some serious issues near high powered cables. You can also easily monitor any kind of relays based sensors just by connecting the RX and TX of RS232 to relays ends and periodically checking port for echos, this way stuff like reading out smoke detectors with relays modules or "water sensor" (2 naked cables separated by paper) are peanuts to do. It is also possible to check for airflow this way, you could construct the little relays which bends over and connects while airflow is present and opens up when it is not. This needs a space with STRONG airflow to be consistent though. A/C voltage is an interesting one, I was looking for a while for some kind of "energy meter" which would allow readout of info via RS232, so we could measure real power consumption vs load ratio but I could not find any. Easiest way to do this stuff is to read out UPS ratios, most "smart" UPSes support that in one or another way. You can read all info and present it via SNMP for later analysis, we use net-snmp with embeded perl, I can send you sample of our module if you wish, it is fairly simple. I would be very interested by ideas regarding detailed airflow readout, it was always interesting me but I could not find any easy solution, only those big "weather stations" which I could not install into any of out airpipes.

Environnemental monitoring
by Olivier Beytrison 02 Apr '08

02 Apr '08

Hi SwiNOGers ! We're looking here in my company to do some extra environmental monitoring. We're mainly looking for some temperature, air flow and AC voltage monitoring. We don't really want to invest in expensive solutions like APC's one, or Rittal. The sensorProbe products (from either AKCP or BlackBox) are quite interesting. And you, what do you have in your datacenters ? Any hints to some other good products ? Have a nice day! -olivier -- Olivier Beytrison Network & Security Engineer, HES-SO Fribourg Mobile: +41 (0)78 619 73 53 Mail: olivier(a)heliosnet.org

Bluewin email problem?
by ralf.zenklusen＠barinformatik.ch 01 Apr '08

01 Apr '08

Since a few weeks we see larger email queues to bluewin from time to time. Today it seems impossible to send emails to bluewin. Is there a general problem? Could somebody from bluewin otherwise contact me off list. Thank you Ralf Zenklusen --- BAR Informatik AG Gliserallee 16 3902 Brig-Glis

Latency problems to Lambdanet?
by Benoit Panizzon 01 Apr '08

01 Apr '08

Good morning We have a few gamers among our customers. They complain that they have latency problems to their favourite gameservers hosted @ lambdanet: 79.133.42.114 78.143.13.126 193.192.58.122 So I put the customer and those servers in our smokeping tool. They show the problem is not on the customer side, but on the server side. Latency to all of those game servers increases to 60ms every evening. So I also put the lanbdanet router ip into smokeping. Same problem there. Peering is via TIX - no problem with the bandwidth usage. Those gamers pretend the latency problem only occurs from our network and not from others like bluewin. Do others also experience latency problems to lambdanet in the evenings?

Re: [swinog] Has Bluewin a DNS Problem

Salut, Kurt, On Wed, 26 Mar 2008 15:03:40 +0100, Kurt A. Schumacher wrote: > What about the most stupid wanabe Spam-fighter which are very unhappy > as in place (e.g. the third-party service provider systems acting > with some SC subsidiaries...) which high rate valid messages if > certain brain-dead conditions like PTR not matching MX don't match? 2 points about this. 1. it is highly unlikely that these stupid wannabe SPAM filters get the response containing so many PTR records right. It is most likely that either the software blows up or that it only ever considers the entry it receives first. (Most likely the software blowing up will not even be remarked but instead the mail will be rejected silently.) 2. Since a lot of people use personalized domains now in their mail addresses (me(a)first.lastname.ch, bla(a)pascual.garnier.name, whatever), the people who use such a setup will be strongly discouraged very quickly and be forced to drop it, since they want to still be able to send mail, most likely. We should not make such stupid moves just to encourage them to adopt such a setup. > Under the line, it is likely not a DNS issue, but the inability by > some mail or AS systems resolving lists.

It is also a DNS issue, depending on the number of results returned; the size of a DNS/UDP response is limited to 1 UDP packet, which again is limited in size. Not everyone uses DNS over TCP, and it is unlikely to be adapted just because of such a stupid and useless SPAM filtering measure. Tonnerre
