domain name system - DNS Question: Run own server, use registrar's, or 3rd party company?




I was wondering... whats the best place to host DNS at? For quick propagation, security, and etc?



I always hosted DNS on my own server.... which gave me a lot of control.... but hosting DNS on the same box as http is never a good practice. What are the advantages of using the domain registrar's dns and simply poining the A record to your ip? What about those commerical DNS hosting companies, that charge ~$35/year for it. Are they worth it?


Answer



I can tell you reasons for and against, from my point of view.



First, I run my own servers. Why I do this is both for professional reasons (I write DNS software for a living) and historically geeky ones. I used to love running my own stuff, doing what I wanted with it, and spending hours a day tweaking this or coding up that.



The reasons you might want to run your own as well are many, and you touched upon a few big ones: If you run your own, you have full control, full knowledge that what you put in is what you get out, and no one to fight with on the phone when it breaks.




The reasons against it are: you are all on your own if it breaks, you have to deal with any upgrades of software needed, and you have to understand zone files and other bits.



Now, if you choose to have someone else host it, I would look into these things. Remember, this is somewhat geeky -- many won't care about some of these features, but I would.




  • Do they support DNSSEC? If not, will they soon? There are a myriad of other questions to ask here, like will it cost more to use DNSSEC? How are keys handled?

  • Do they serve over IPv6? If not, will they soon?

  • How much control do you have over your zone? Suppose you want to add an "unusual" record, can you?

  • How geographically distributed are their systems?

  • How much does their editing UI suck? It will, probably. Just how much is the question.


  • Can you update via dynamic DNS?



I finally chose to run my own server, but have someone else actually serve my zones to the public. sns.isc.org pulls from my servers, so I maintain all the content, just don't have to worry about the big headaches.

iLO 3 Firmware Update (HP Proliant DL380 G7)

The iLO web interface allows me to upload a .bin file ( Obtain the firmware image (.bin) file from the Online ROM Flash Component for HP Integrated Lights-Out. ) The iLO web interface redirects me to a page in the HP support website ( http://www.hp.com/go/iLO ) where I am supposed to find this .bin firmware, but no luck for me. The support website is a mess and very slow, badly categorized and generally unusable. Where can I find this .bin file? The only related link I am able to find asks me about my server operating system (what does this have to do with the iLO?!) and lets me download an .iso with no .bin file And also a related question: what is the latest iLO 3 version? (for Proliant DL380 G7, not sure if the iLO is tied to the server model)

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...

linux - How can I get my mediawiki to stop thinking I have cookies disabled?

I've searched half a day for how to resolve this issue, and can't figure it out. Shortly after I made my wiki a simple private wiki according to the instructions at Mediawiki's website, it started giving me this weird login error message: Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again. If I remove those private wiki settings, the error disappears, even if I try logging in. But I need it to be a private wiki for only my team. So what do I do? Here's what I've done so far. Just to be safe, after ever change, I try rebooting Apache using: sudo /etc/init.d/apache2 restart In my php.ini file, I have the following set: session.save_path = "/var/lib/php5" session.cookie_secure = secure session.cookie_path = /tmp session.cookie_domain = my server's internal URL (should I even set this? this field was blank before, but not commented out) session.referer_check = Off I ran the following to ensure that the fold...
