Jul 3	comment	Timesync on HyperV with CentOS 6.2 Nevermind messages about time-sync errors, there are no messages for that provider at all. There are other Hyper-V messages, but none for TimeSync.
Jul 2	comment	Timesync on HyperV with CentOS 6.2 It does say "Heartbeat: OK", so it seems at least the communications channel is open.
Jul 1	comment	Timesync on HyperV with CentOS 6.2 Interesting question, not sure how to tell. They show started in the guest, and I assume they wouldn't do that if they hadn't communicated with the host, but I can't say for sure. I don't have scvmm so I'm not sure ow to tell either.
Jul 1	comment	Timesync on HyperV with CentOS 6.2 Yes, all services are enabled.
Jul 1	comment	Timesync on HyperV with CentOS 6.2 Sorry for the downvote, but these are precisely the tweaks that aren't supposed to be needed with the plugable timesource in the new integration components.
Jun 25	comment	Timesync on HyperV with CentOS 6.2 Yes, the time is fast not slow. Which is even odder as the typical VM clock issue is the loss of time, not the gain of time.
Jun 6	comment	IIS 7.5 returning 404 for unknown host names Yup, MS claims this is by design too. :-) But given that simply installing WCF, or it seems having a Windows 7 client (because of the branch cache, don't know if that will happen in W2K8/12), causes the server to return a 404 for ANY site, configured on the server or not, I can't believe that's the "correct" behaviour. As for the option of ending the apppool vs. the site, that only helps if there's a 1-1 mapping from site to app pool. Helps me, but may not help all.
Jun 5	comment	IIS 7.5 returning 404 for unknown host names Ah, but per my reading of the documentation, the uriprefix must also match, after all, the reservation was for a specific uriprefix space, not the entire space. Also, it seems WCF isn't the only thing to register a wildcard (http://+:80) reservation, branch cache does too. Can't convince me the "design" is that any server with either WCF or a branch cache potential CLIENT (windows 7 machine) should answer with a 404 for a site that isn't defined on that server.
Jun 5	comment	Nginx Retry of Requests ( Nginx - Haproxy Combination ) OK, so I'm really late responding to you now. :-) I'm not sure, now you need someone that understands the inner workings of sockets in Linux. HAProxy does start the new process before the old one ends, but I don't know sockets on Linux enough to know how the handoff of the listening socket works. I would think that process A would have to close it before process B could open it, and there's your hole, but maybe A can had B the listening socket? Don't know.
Jun 5	comment	optimizing websites performance ( nginx/mysql/wordpress ) I play w/the proxy_pass, not fastcgi_pass, but looking at the wiki I'd say they follow the same rules, as they both can use the backend directive too. So take a look for some of the buffering options of fast_cgi and see if you can turn it off, not sure if you can.
Jun 4	comment	optimizing websites performance ( nginx/mysql/wordpress ) Did you put the proxy_pass directive into your config file?
Jun 4	comment	IIS 7.5 returning 404 for unknown host names There are other sites running on the machine, so netstat shows port 80 in use. Actually figured it out (and I think it's a bug, will chase MS later) answer below.
Jun 4	comment	IIS 7.5 returning 404 for unknown host names Not only is the default site stopped, I actually deleted it just to make sure HTTPSys wasn't doing something daft like seeing the registration for the wildcard binding even it the site was stopped. As for the HTTP Module, if the site is stopped then none of the modules should fire anyway, right? A stopped site should be the same as no site. And I even tried it with a name that doesn't exist, so there was no site entry and it still returned 404. Only when I stop IIS totally (all sites) do I get a reasonable return
Apr 4	comment	Nginx Retry of Requests ( Nginx - Haproxy Combination ) Actually I think this isn't even an nginx specific problem as the root of the issue here is that there is a window (small, but real) between when the old process closes the ports and the new process opens them where requests can get dropped on the floor. I wonder what the pure HAProxy answer to this is.
Mar 27	comment	http or https when including jquery from google API The double // without a scheme is supported by all major browsers and has been in the browsers standard for many years (maybe from the beginning.) It's a great gem and saves lots of silly (if ssl then .. else ..) type checks.
Mar 23	comment	Symantec Endpoint Protection Small Business disabling Windows 2008 R2 Firewall, how do I stop this? You can create groups w/different policies, and you can "turn off" the SEP firewall, but that will not leave the Windows firewall enabled. Apparently this is different behaviour from the Enterprise version of SEP.
Mar 22	comment	Symantec Endpoint Protection Small Business disabling Windows 2008 R2 Firewall, how do I stop this? I wish. Nope, can't create a custom install like that in small business -- my options are "AV/Anti-spyware only" or "full". So if I did the AV only it might (should) work, but I'd be missing the network threat protection stuff. I think you are correct that I can do that in the non-small business version.
Mar 13	comment	Nginx Retry of Requests ( Nginx - Haproxy Combination ) OK, you had me worried that HAProxy wasn't doing what it's supposed to, so I just did a trial. Page sleeps for 10 seconds and then returns. I restarted HAProxy in the middle of the request and the request finished w/out a hiccup. HAProxy did not drop the connections. So, I think there's a configuration problem either in your HAProxy setup, or your restart script. My restart script is on the next answer (code blocks don't work in comments)
Mar 12	comment	Nginx Retry of Requests ( Nginx - Haproxy Combination ) I guess there's a very small timing hole where the old instance of HAProxy has stopped listening and the new instance hasn't started yet. If your requests are hitting at that point I guess they'd fail. The timeout from nginx seems to be a combination of proxy_connect_timeout and proxy_read_timeout. But the only one that should matter in your case is proxy_connect_timeout as the read timeout only matters once connected, and HAProxy better not be dropping connected connections. BTW, how do you know you're dropping connections? That's a very small tining window to worry about.
Mar 22	comment	Disabling Recursion in DNS on Windows 2008 R2 Server Core Sadly this strikes me as wrong as effectively the server is trying to do lookups but is unable since it has no root hints, vs. not trying to do them in the first place. But the net effect is the same.
