• mac + parallels and https site test = router restarts

  - by Erik

  Ok I have an interesting & very frustrating problem happening. I'm going to explain it the best I can. I work as a graphic designer & web designer on a mac and have a Comcast internet connection that comes through a Comcast branded router (SMC8014) which then ties into an Airport Extreme Base Station which runs my office network. I run OS 10.5.7 and also run Parallels 4.0.3 (running Windows XP) for testing websites in Internet Explorer and so on. Ok, so that the basic background. Here's my issue. I've been collaborating an ecommerce website with another designer/developer and when testing the site on the PC side we have started to run into some sort of network problem. The site is https if that matters at all I suspect it may. Basically when I run parallels for testing I am constantly having to restart the router in order to connect to the test site (it's hosted). Funny thing is I can access the rest of the internet fine, just not this site I'm working on until I restart the router (It's sorta like the site is timing out). This never happens when just running the Mac side of things. It only becomes an issue when Parallels is open and I am doing page refreshes while making css or HTML edits via something like Coda or CSS edit (connected to the hosting server via ftp). The real problem is that once the problem starts I only get about 2 or 3 page loads before I have to restart the router again. It's absolutely crippling. I cannot get any work done when I have to restart the router every couple of minutes. So, if you think this problem is isolated to me, the answer is no. The designer/developer I'm collaborating with has an office a couple miles away and experiences very similar problems under slightly different setup. He also has Comcast as his internet provider and connects his router to an Airport and primarily works on a mac. The main difference is that rather than using a visualizer like parallels to test the website on the PC he uses a real live PC that is on his network. Once he fire up the PC to do testing he runs into the same issue described above. After a couple of page refreshes in Internet Explorer or other browser on the PC the site becomes unresponsive and the router has to get restarted. Any thoughts on what is going on here would be greatly appreciated. Thanks in advance.

• Windows 2008 additional disk going offline with reboots on Amazon EC2

  - by Ernest Mueller

  OK, so I took the stock Windows 2008 64-bit Amazon AMI and wanted to add a D: drive for page file space and crash dumps. I launched the instance with a second EBS volume attached as xvdf and went into Disk Management set it online, and added the page file and crash dump settings and all that works. But when I reboot, the box comes back up with that second drive as "Offline." How do I get that disk to automatically come online on reboot (or most notably, when I turn this into an AMI and launch more instances off it - I've tried that too and same deal with the D:).

• How does MySQL 5.5 and InnoDB on Linux use RAM?

  - by Loren

  Does MySQL 5.5 InnoDB keep indexes in memory and tables on disk? Does it ever do it's own in-memory caching of part or whole tables? Or does it completely rely on the OS page cache (I'm guessing that it does since Facebook's SSD cache that was built for MySQL was done at the OS-level: https://github.com/facebook/flashcache/)? Does Linux by default use all of the available RAM for the page cache? So if RAM size exceeds table size + memory used by processes, then when MySQL server starts and reads the whole table for the first time it will be from disk, and from that point on the whole table is in RAM? So using Alchemy Database (SQL on top of Redis, everything always in RAM: http://code.google.com/p/alchemydatabase/) shouldn't be much faster than MySQL, given the same size RAM and database?

• Severe latency only on one machine and only when accessing intranet site

  - by Joe M.

  I have one desktop machine that is having consistently high latency only when trying to load a page from an intranet site. Using the Chrome Developer Tools, the site shows a "Waiting" time of 4-5 seconds each page load. Other machines have <50ms, and the problem machine loads regular internet sites with <1s latency, so the problem is only on one machine and only when accessing the intranet site. This is a small business and all the hosts are on 192.168.0.1/24 I would have suspected a connection issue with the problem machine but normal internet sites are not having latency. Then I would have looked at connection issues with the intranet web server but other machines are not having latency to it. What else can I look at to troubleshoot this?

• Set a custom favicon locally, that carries across the entire site.

  - by Iszi

  Is there a way to add a custom favicon to an App Tab? In the above thread, @admintech links to a great plugin for changing favicons which covers both the bookmarks folder and the address bar/tab bar icons. However, it still does not quite fully address what I was hoping to accomplish. I'd like to set an App Tab that has a customized icon, that stays the same in that tab no matter what I do there. Since the navigation within an App Tab is very restricted, the chosen favicon should always be relevant to whatever page is loaded in that tab. The Bookmark Favicon Changer has been effective in allowing me to use a custom favicon in the App Tab. But, the favicon only applies to the specific URL that was bookmarked. Any navigation done from that page will return the favicon to blank. Is there another plugin, or perhaps some special tweak to this plugin or the bookmark itself, that will allow me to make the favicon more persistent across the site?

• Django HttpResponseRedirect acting as proxy rather than 302

  - by Trevor Burnham

  I have a Django method that's returning return HttpResponseRedirect("/redirect-target") When running the server locally, if I visit the page that returns that redirect, I get the log output [17/Oct/2013 15:26:02] "GET /redirecter HTTP/1.1" 302 0 [17/Oct/2013 15:26:02] "GET /redirect-target HTTP/1.1" 404 0 as expected. But, when I visit that page in Chrome, the Network tab shows the request to /redirecter with the response from /redirect-target, rather than showing the 302. cURL does the same: $ curl -I -X GET http://localhost/redirecter HTTP/1.1 404 Not Found date: Thu, 17 Oct 2013 19:32:30 GMT connection: keep-alive transfer-encoding: chunked In production, the same Django code does show a 302 redirect in Chrome and cURL. What could be going on here? Is there some kind of Django setting that might be causing it to proxy the target rather than send a redirect when HttpResponseRedirect is used (but lie about it in the log)? Or is there a quirk on my system (OS X) that might cause localhost redirects to behave this way?

• Automatically mount a remote folder on boot

  - by Andrew

  I'm trying to mount a Windows folder on my Ubuntu machine on start up. I've tried following this page here, modifying /etc/fstab and appending sshfs#my_user@remote_host:/path/to/directory <local_mount_point> fuse user 0 0 to it, but it fails; on start up, I get an error saying that the mounting failed, and I can press S to skip or M to recover manually. I also tried following this page here, appending /usr/bin/sshfs -o idmap=user my_user@remote_host:/path/to/directory <local_mount_point> to the /etc/rc.local file, but this doesn't help either; Ubuntu just boots up normally without mounting. I have Cygwin installed on my Windows machine, and I can run everything smoothly, such as sshing without passwords, and mounting it manually. I've also tried to run the modified rc.local file $ /etc/rc.local, and it works perfectly, but I just can't seem to get the folder mounted on start up. Can someone help me?

• Windows 7 PC browsers having trouble to open certain sites but not others

  - by user55345

  Hi, My Win7 PC these days acting very weird: Examples: It can not open bing.com, alexa.com, msdn.microsoft.com (blank page or page can not be found); It can open zdnet.com but lost all CSS layouts and pictures; It can open stackoverflow and Google no problem; I tried all three browsers (IE8, Chrome, Firefox 3.6) same thing. I didn't change anything on this PC in days. This PC does have Anti-Virus installed and updated. I'm also pretty sure it's not a network problem, because my other laptops are just fine at the same time. The only thing I can think of is it might be some auto-update stuff underneath happened without my knowledge, but I have no idea where to troubleshoot? Please shed some lights for me? Thanks a lot.

• Acrobat 8 on Windows 7 64-bit

  - by user66822

  Here's the situation I'm in. I have Acrobat 8 on Wows 7 (64-bit) and anytime I create PDFs any numbers on the page I'm PDFing come through as garbage. Everything else on the page comes out fine, just the numbers are messed up. They appear as random symbols. I've uninstalled, reinstalled. Applied all updates, not applied updates, nothing seems to help. Mayube I'm a bad searcher, can't put in the right search terms, but I can't find anything that seems to point me in a direction on this. ANy ideas?

• How to build an outbound load balancer with linux?

  - by matnagel

  We have a small house in the countryside and there is no fixed broadband, so we had a mobile flatrate first, and for 2 people with 2 computers it was too slow, so now we have 2 flatrates for 2 client machines. So I pay 2 flatrates and have double bandwith theoretically. There is a local network in the house that connects everything. But when I am alone I wonder how I can use both connections at the same time. I want to build a solution where I can browse the web and page requests are spread between the 2 connections. I imagine there are expensive routers who can split the traffic between 2 lines. But is there a good way to do it with linux? The solution I am looking for will split the requests already for one page (multiple images, css files, javascrfipt files) between the two lines.

• Clean URLS with mod rewrite and URL Encoded characters causes 404?

  - by Richard JP Le Guen

  I have a web site using mod_rewrite to get some clean urls and custom 404 pages. My .htaccess file looks like this: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?clean_url=$1 [QSA,L] </IfModule> What puzzles me is that if the URL contains a %2F (url-encoded /) the server seems to force a 404. As an example, http://example.com/category/article would be a normal article, but then http://example.com/category%2farticle gives a server-generated 404 page. (not the custom 404 page) I wouldn't have expected this... why this is happening? Is there a way around it?

• Okular (on Ubuntu 9.10) prints multiple pages per sheet (n-up) very small

  - by dgleich

  I'm trying to print a set of beamer slides with multiple slides per page (4-up or 6-up). When I select 4 pages or 6 pages per sheet in the Okular print dialog, the pages print quite small (perhaps even tiny -- about 1.75" by 1.25") and leave significant white-space on the page. I can get around this behavior by using the pdfnup utility (in the pdfjam package); which will correctly generate a 4- or 6-up pdf file but it's annoying to generate a second pdf file when I should be able to accomplish this task from the print dialog. Details: Ubuntu 9.10 (Karmic), 64-bit, Color Postscript printer.

• 504 Gateway Time-out after php fatal error

  - by tiagojsag

  I'm using nginx and php-fpm to develop a symfony2 based website, under ubuntu 12.10 (yes, I know I'm using a beta OS). Everything was working out fine until, due to an error on my code, I called an unexisting function, and got the following: Fatal error: Call to a member function (....) This isn't a problem (it's a bug in my code, easily fixable), but after this, no other page loads. My browser just keeps trying to load the page from the webserver, until nginx timeouts (after +- 30s, which should be some default timeout) and returns: 504 Gateway Time-out Restarting php-fpm solves the issue. Nginx logs show a timeout message, and nothing appears on php-fpm logs, even if I set them to debug level. I tried switching from fpm to fastcgi, and the same thing happens. I've looked around, but all similar error are related to big requests/file handling, which isn't the case. All the pages on my website load in a few seconds, even under development conditions (no caching, etc).

• Hiding a HTTP Auth-Realm by sending 404 to non-known IPs?

  - by zhenech

  I have an Apache (2.2) serving a web-app on example.com. That web-app has a debug-page reachable via example.com/debug. /debug is currently protected with a HTTP basic auth. As there is only a very small user-base who has access to the debug-page, I would like to hide it based on IP address and return 404 to clients not accessing from our VPN. Serving a 404 based on IP-address only is easy and is described in http://serverfault.com/a/13071. But as soon I add authentication, the users see a 401 instead of a 404. Basically, what I need is: if ($REMOTE_ADDR ~ 10.11.12.*): do_basic_auth (aka return 401) else: return 404

• Why doesn't SuperGenPass work on some sites when I use Chrome?

  - by Lunatik

  Bookmarklet SuperGenPass sometime fails to popup when I click the bookmark in Chrome. It does however work when on the same page works in Firefox; an example is http://www.engadget.com/login This behaviour also replicated on a new Chrome tab (understandably, there is no domain), but some sites just fail to launch it meaning you have to go to another site, open it up, enter in [something] to get the 'Regenerate password' link, enter the domain manually then finally enter your master password to get the generated password! Something about the makeup of the page seems to make SuperGenPass think that it isn't able/required to popup. The FAQ doesn't make any mention of this fact, neither does a quick Google turn up anything that looks relevant. Does anyone else have the same issue? How can it be fixed? I'm on Windows using the current release of Chrome (5.x at the moment, but probably 18.x by the time you read this next week based on Google's seemingly logarithmic release numbering).

• How to print 4 index cards on a single A4 sheet in Word 2003

  - by Anna

  I have an index card designed in Word. It's fairly complicated with graphics, borders and background. The page layout has been set to landscape and with size set to 4x6. How can I print this, 4x per A4 landscape sheet? I cannot for the life of me work it out. The printer always seems to do a single card per A4 sheet, wasting 3/4 of the page. "Pages 1,1,1,1" will result in 4 sheets being printed. What am I doing wrong?

• Meta refresh tag not working in (my) firefox?

  - by mplungjan

  Code like on this page does not work in (my) Firefox 3.6 and also not in Fx4 (WinXPsp3) Works in IE8, Safari 5, Opera 11, Mozilla 1.7, Chrome 9 <meta http-equiv=refresh content="12; URL=meta2.htm"> <meta http-equiv="refresh" content="1; URL=http://fully_qualified_url.com/page2.html"> are completely ignored Not that I use such back-button killing things, but a LOT of sites do, possibly including my linux apache it seems when it wants to show a 503 error page... If I firebug or look at generated content, I do not see the refresh tag changed in any way so I am really curious what kind of plugin/addon could block me which is why I googled (in vain) for a known bug... In about:config I have accessibility.blockautorefresh; false so that is not it. I ran in safe mode and OH MY GOD, STACKEXCHANGE IS FULL OF ADS but no redirect

• Bugzilla random lag and CPU usage

  - by Serty Oan

  Here is the configuration : Bugzilla (3.4.2) application running on a Ubuntu server 8.04 with Perl 5.8.8. Here is the problem : Sometimes (randomly), pages take very long to load. It can be any of the login page or query.cgi page or buglist.cgi... etc... Using top on the server, I tried to see what was wrong, and saw that sometimes a bugzilla script would use 30% memory and last pretty long (1 to 5 seconds) and sometimes not even show in the list because it responded too quickly or just use 2%. The mysqld process does not seems to be the problem.

• Running Multiple sites with multiple domains apache

  - by PsychoData

  I am having a rough time running apache and using multiple domain names here is a snippet of my config file. I keep getting a error saying that NameVirtualHost has no VirtualHosts. I want them both running on the same IP and I'm not sure why this doesn't work. I've been digging through the documentation for VirtualHosts, NameVirtualHost, and apache's page about name based virtual hosting. That example in the name based page is almost exactly my config! What am I doing wrong?

• PHP Script causing high CPU

  - by user20996

  I have a website which is causing me a major headache. There is one PHP script which is using far to much CPU, this only seem to happen when bots hit the site, I dont want to block all the bots because we need them. I have the the process manager output: Pid Owner Priority CPU % Memory % Command 16943 (Trace) (Kill) specialone 0 99.4 1.0 /usr/bin/php /var/www/specialone/page.php I ran strace -p 16943 on the process but it comes up with nothing. We have 2GB of RAM and the php memory_limit is set to 128M which should be enough. The trouble I have is the PHP code is a Framework and the culprit page.php pulls in a lot of other PHP files so I cant debug the PHP. Is there any way of finding out what the script is doing when its using so much CPU which will help me solve it?

• No recent docs listed in Office 2007 on Windows XP Pro

  - by user58094

  Hi, I have Office 2007 installed on a laptop running Windows XP Pro. When I go to open a file in Excel or Word, there is no list of recent documents. On the Options/Advanced page, the "show this number of recent documents" spinner displays 0 but is grayed out so I can't change it. The help page it directs me to describes how to disable the list, but not how to enable it. In Word, it says something about the list being disallowed by Group Policy, but I am not part of any workgroup and, as far as I know, the policies are all uninitialized, so it should be allowed by default. There are recent files listed in MRU keys in the registry. A similar question has been answered, but I believe that only applies to Windows Vista or 7 because the folder mentioned doesn't exist on my system. Instead, the folder "%APPDATA%\Microsoft\Office\Recent" contains shortcuts to recent docs for both Excel and Word. Any other ideas? Thanks.
