Re: [swinog] Environnemental monitoring
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 Oliver, For temperature it all depends on how many positions you wish to monitor, perhaps the cheapest (In terms of time plus cost) is solution which is offered by Distrelec, look it up on their site, it has article number 866230. 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.

Re: [swinog] KVM-over-IP
Steven, From what I have seen so far, the most portable solution are the KVMs from Startech. They got it all, VNC, JAVA client which works with any Java Capable OS, Radius for Auth and so on. Unfortunately they do not make a CAT5 KVM :( but as others have adivised you could buy a KVM to IP bridge from them and use it with your existing KVM solution. Their p/n for it is SV1110IPEXT If you want to go really cheap: Look out on Ebay.com, this extender pops up there regularly and goes for around 200$, which, considering current dollars condition is a steal. Another nice solution is IMHO latest Raritan Dominion KVMs, those are pretty reliable and nice but very pricey.

Hello, I can vote for Host Europe. http://www.hosteurope.de/produkte/Server-XL-XXL They are not the cheapest but the service quality is excellent and I have been with them for years already, never had an issue. Those are Dell Servers with DRAC4 cards, I have Solaris installed on mine, installed it over net.

I found a lot of companies that offer only managed root servers - in my case I explicitly need a unmanaged one. Optionally, it should also be possible to remotely install the servers operating system from my own installation source (e.g. uploading an ISO image or doing the install using some rescue boot systems provided by the provider). Does anyone on this list has recommendations of companies who offer this service? It must not necessarily be a Swiss company, every other country is fine as well. I already found a lot of companies who offer this service - but since I really need a good service quality, I'm seeking for recommendations and experiences from a customer perspective.

Re: [swinog] Mail server - Unix
Nico, For domain toaster of that size, qmail-ldap is a nice solution, but software seems to be orphaned now, as soon as some major SMTP enhancements come in I am afraid qmail will slowly die out. As some have already mentioned, the Maildir format used by Qmail is suboptimal for handling large boxes, expecially with IMAP, I would strongly advise to use IMAP daemon which features caching mechanisms, such as Cyrus IMAP. Cyrus is great plus you get Sieve server side filtering but it is a challenge to get it working with Qmail, especially with virtual boxes. If you go with some non-caching IMAP daemon like courier, then it might make sence to setup IMAP Proxy too which would keep alife the IMAP connections for let`s say 2 min and reuse it for same user, so new IMAP processes do not have to be spawned and mailboxes rescanned every time web mail refreshes. Of course this hogs memory but is useful sometimes, especially if users have thousands of mails. Frontend: Squirrelmail. By far most powerful web based MUA out there IMHO. Also very easy to ehnance, we wrote a LDAP control panel to it for example, so users can setup aliases, forwarders and away messages themselves. (Contact me offlist if you want it, I can send it to you).

Just wanted to ask what setup you use or recommend for large scale sites (~10k users, some hundreds of imap(s), smtp, webmail connections, about 5-10 mails incoming and outgoing per second): - what smtpd? why? - what mail retrieval solution for which protocol? - if you offer webmail, what do you use? - it should be *nix software, preferable FOSS (free and open source software) - Which Antispam / Antivirus protection do you use? And what is the success rate? I'm personally deep into qmail+patches+patches+patches of patches plus courier and dovecot. The problem with qmail is that you need either a big patchset or a once patched setup and reuse that. Plus qmail really has some not-so-nice bugs. On the other hand, there seems to be no MTA out there, that can be configured so easy like qmail (ever created a mail addr with cp .qmail-template .qmail-domain-user with another MTA?).

Re: [swinog] Providers supporting TLS (for SMTP, POP, IMAP, ...)?
Hi all, The subject says it all: do you know which providers support TLS (the technology formerly known as SSL) for SMTP, POP and/or IMAP for their residential or small-office dialup/broadband customers? TLS for SMTP makes no sence since this will only protect your message enroute from your machine to SMTP server but after that it is all open again. POP3 and IMAP with TLS (AKA POP3s and IMAPs) are available from number of providers such as Bluewin but not largely advertized. Why? I think the main reason is because compared to POP and IMAP, it is harder to set up this correctly within the MTA and can introduce many additional problems and errors. Providers are afraid of extra support calls. If user explicitly asks for this, then it can be assumed he knows what it is all about and will be able to set it up correctly himself.

Re: R: [swinog] SDSL
Do you mean Cablecom is currently illegal if it is offering copper G.SHDSL lines doing 8M on 2 wires? -Manuel You mean 2 pairs? G.SHDSL currently tops out at 4.8mbit per copper pair/loop. Actually I also heard about Cablecom offering 4/8mbps lines on 1/2 copper pairs. Not sure if this is their own copper or leased from Swisscom though. ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
Re: [swinog] Formmailer-Scripts and Spam
I will never recommend PHP to a customer or even a friend; however I heard about an Apache module (by SuSE apparently) which is designed as a security layer for mod_perl and mod_php. I haven't even tried it yet, but I will the next time I need to support others' bad decisions. If you know what you are doing and develop PhP application with security in mind from the first moment, 95% of all potential PhP exploits can be avoided. Absolutely strict, brutal and dictatoric input validation as a first action of the application is a must in any PhP project. Only variables explicitly allowed to pass should be passed and checked at least for their data types and sizes. Plus additional checks if needed. The CPU cost of such checks are fairly low. On a sidenote: mail() is not very optimal solution for mailings anyway, full SMTP stack implementations such as PHPMailer are better, although not exploit free solution. -- Kirill Ponazdyr Technical Director Codeangels Solutions GmbH Tel: +41 (0)43 844 90 10 Fax: +41 (0)43 844 90 12 http://www.codeangels.ch http://www.codeangels.com ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
