• SPF problems with Google Apps

  - by mahle

  I currently have an SPF record with a hostname of @ that is: v=spf1 mx ip4:x.x.x.243/32 include:_spf.google.com include:amazonses.com ~all I also have another record of" spf2.0/pra mx ip4:x.x.x.243/32 include:_spf.google.com include:amazonses.com ~all We have had a lot of email being bounced back because of spam and now when I go to http://www.kitterman.com/spf/validate.html? and check the "Does my domain already have an SPF record? What is it? Is it valid?" it says no spf record exists. However, when I send an email using our Amazon SES script and check the headers it says it passes the SPF test. Is there something I am missing? Do I need to place that text in quotes ""? Any help would be greatly apprecaited.

• Unable to restore from Shadow Copy due to long filename

  - by Spongeboy

  We have shadow copy enabled on our Windows SBS 2008 server. Attempting to restore a file from shadow copy gave the following error- The source file name(s) are larger than is supported by the file system. Try moving to a location which has a shorter path name, or try renaming to shorter name(s) before attempting this operation. The filename has 67 characters, and it's shadow copy path is 170 characters. These seem to be under the NTFS limits (260?). We tried- Copying to the shortest path possible (C:) Copying to the shortest path possible on both a client computer and the server itself Is it possible to rename files in a shadow copy, before doing the copy? Any idea why the error is appearing despite the filename size appearing to be within limits?

• How do I get grep color in the file names before each match?

  - by chimerical

  If I run grep -ir "somethingtomatch" . from the current directory, I typically get results like this: ./some/path/file1.html: filecontent filecontent keyword filecontent ./some/path/file2.html: filecontent filecontent filecontent keyword ./some/path/file3.html: filecontent keyword filecontent filecontent ./some/path/file4.html: keyword filecontent filecontent filecontent I used grep --color=auto -ir 'somethingtomatch" . but it only highlights the keywords in white on a red highlight. I'm trying to get file names on the left color-coded too. How do I do that? I'm using Terminal.app in OS X with bash and xterm (and I tried xterm-color too).

• Trouble installing SSL Certificate on Apache

  - by jahufar

  We have a dedicated server with GoDaddy running Plesk that requires SSL. I've generated the certificate files and I created a vhost_ssl.conf (since I can't edit the default plesk apache configuration http.include, vhost_ssl.conf gets Included to httpd.include) that tells apache where to find the certificate files: SSLCertificateFile /usr/local/psa/var/certificates/domain.com.crt SSLCertificateKeyFile /usr/local/psa/var/certificates/domain.com.key SSLCertificateChainFile /usr/local/psa/var/certificates/sub.class1.server.ca.pem When I stop/start apache, it refuses to start up. The error_log does not have anything on it either (which is strange). Then I opened up httpd.include and found this bit: <VirtualHost 208.xxx.xxx.xxx:443> ServerName domain.com:443 ServerAlias www.domain.com UseCanonicalName Off SSLEngine on SSLVerifyClient none SSLCertificateFile /usr/local/psa/var/certificates/certagC9054 Include /var/www/vhosts/domain.com/conf/vhost_ssl.conf Then I commented out SSLCertificateFile /usr/local/psa/var/certificates/certagC9054 (which is plesk's SSL certificate) and restarted apache and it worked perfectly fine. It seems that Apache does not like multiple SSLCertificateFile within the same VirtualHost directive? As anyone who worked with plesk knows, I can't just remove SSLCertificateFile directive in httpd.include as plesk will overwrite my changes when someone uses it - which is why it's in vhost_ssl.conf. So I'm stuck and this is beyond my meager admin skills. Would appreciate someone who knows what (s)he's doing to tell me whats going on. Thanks in advance.

• SFML programs fails to debug with glslDevil

• Fast programmatic compare of "timetable" data

  - by Brendan Green

  Consider train timetable data, where each service (or "run") has a data structure as such: public class TimeTable { public int Id {get;set;} public List<Run> Runs {get;set;} } public class Run { public List<Stop> Stops {get;set;} public int RunId {get;set;} } public class Stop { public int StationId {get;set;} public TimeSpan? StopTime {get;set;} public bool IsStop {get;set;} } We have a list of runs that operate against a particular line (the TimeTable class). Further, whilst we have a set collection of stations that are on a line, not all runs stop at all stations (that is, IsStop would be false, and StopTime would be null). Now, imagine that we have received the initial timetable, processed it, and loaded it into the above data structure. Once the initial load is complete, it is persisted into a database - the data structure is used only to load the timetable from its source and to persist it to the database. We are now receiving an updated timetable. The updated timetable may or may not have any changes to it - we don't know and are not told whether any changes are present. What I would like to do is perform a compare for each run in an efficient manner. I don't want to simply replace each run. Instead, I want to have a background task that runs periodically that downloads the updated timetable dataset, and then compares it to the current timetable. If differences are found, some action (not relevant to the question) will take place. I was initially thinking of some sort of checksum process, where I could, for example, load both runs (that is, the one from the new timetable received and the one that has been persisted to the database) into the data structure and then add up all the hour components of the StopTime, and all the minute components of the StopTime and compare the results (i.e. both the sum of Hours and sum of Minutes would be the same, and differences introduced if a stop time is changed, a stop deleted or a new stop added). Would that be a valid way to check for differences, or is there a better way to approach this problem? I can see a problem that, for example, one stop is changed to be 2 minutes earlier, and another changed to be 2 minutes later would have a net zero change. Or am I over thinking this, and would it just be simpler to brute check all stops to ensure that The updated run stops at the same stations; and Each stop is at the same time

• Where to place Nginx IP blacklist config file?

  - by ProfessionalAmateur

  I have an Nginx web server hosting two sites. I created a blockips.conf file to blacklist IP addresses that are constantly probing the server and included this file in the nginx.conf file. However in my access logs for the sites I still see these IP addresses showing up. Do I need to include the black list in each site's conf instead of the global conf for Nginx? Here is my nginx.conf user nginx; worker_processes 1; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; keepalive_timeout 65; include /etc/nginx/conf.d/*.conf; # Load virtual host configuration files. include /etc/nginx/sites-enabled/*; # BLOCK SPAMMERS IP ADDRESSES include /etc/nginx/conf.d/blockips.conf; } blockips.conf deny 58.218.199.250; access.log still shows this IP address. 58.218.199.250 - - [27/Sep/2012:06:41:03 -0600] "GET http://59.53.91.9/proxy/judge.php HTTP/1.1" 403 570 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)" "-" What am I doing incorrectly?

• What paths are guaranteed to exist on Windows Server 2008 R2?

  - by jpmc26

  What paths are guaranteed to exist on a Windows Server 2008 R2 instance? A client is requiring that some instructions specify exact paths in all cases. (The person executing said instructions is not supposed to have to decide on any path themselves, even when the path makes absolutely no difference.) So I need to know what paths I can rely on to be there. It's fine with me if they involve environment variables, but they need to be variables guaranteed to hold an existing path. (That is, no modification to a path that doesn't exist possible.) Or are there no guaranteed paths?

• Strange Apache Webdav situation (OSX Will connect, Ubuntu will not)

  - by mewrei

  So basically my situation is that I have an Apache 2.2 webserver running on Linux on another box, and I have it configured to serve up webdav. Now here's the weird part, I can access the server just fine on my Mac using the "Connect to Server" dialog (even moved like 5GB of files over the connection). On my Ubuntu desktop cadaver will connect as well and allow me to browse. However when I try to use Xmarks (BYOS Edition) or the GNOME "Connect to Server" dialog, it gives me a 403 Forbidden error. My server does digest authentication if that makes any difference. Here's part of my apache2.conf file <VirtualHost *:80> DocumentRoot "/path" <Directory "/path"> Dav on AuthType Digest AuthName iTools AuthDigestDomain "/" AuthUserFile /path/to/WebDavUsers Options None AllowOverride None <LimitExcept GET HEAD OPTIONS> require valid-user </LimitExcept> Order allow,deny Allow from All </Directory> <Directory "/path/*/Public"> Options +Indexes </Directory> <Directory "/path/user"> <LimitExcept GET HEAD OPTIONS> require user user </LimitExcept> </Directory> </VirtualHost>

• Handling permissions in a MVP application

  - by Chathuranga

  In a windows forms payroll application employing MVP pattern (for a small scale client) I'm planing user permission handling as follows (permission based) as basically its implementation should be less complicated and straight forward. NOTE : System could be simultaneously used by few users (maximum 3) and the database is at the server side. This is my UserModel. Each user has a list of permissions given for them. class User { string UserID { get; set; } string Name { get; set; } string NIC {get;set;} string Designation { get; set; } string PassWord { get; set; } List <string> PermissionList = new List<string>(); bool status { get; set; } DateTime EnteredDate { get; set; } } When user login to the system it will keep the current user in memory. For example in BankAccountDetailEntering view I control the controller permission as follows. public partial class BankAccountDetailEntering : Form { bool AccountEditable {get; set;} private void BankAccountDetailEntering_Load(object sender, EventArgs e) { cmdEditAccount.enabled = false; OnLoadForm (sender, e); // Event fires... If (AccountEditable ) { cmdEditAccount.enabled=true; } } } In this purpose my all relevant presenters (like BankAccountDetailPresenter) should aware of UserModel as well in addition to the corresponding business Model it is presenting to the View. class BankAccountDetailPresenter { BankAccountDetailEntering _View; BankAccount _Model; User _UserModel; DataService _DataService; BankAccountDetailPresenter( BankAccountDetailEntering view, BankAccount model, User userModel, DataService dataService ) { _View=view; _Model = model; _UserModel = userModel; _DataService = dataService; WireUpEvents(); } private void WireUpEvents() { _View.OnLoadForm += new EventHandler(_View_OnLoadForm); } private void _View_OnLoadForm(Object sender, EventArgs e) { foreach(string s in _UserModel.PermissionList) { If( s =="CanEditAccount") { _View.AccountEditable =true; return; } } } public Show() { _View.ShowDialog(); } } So I'm handling the user permissions in the presenter iterating through the list. Should this be performed in the Presenter or View? Any other more promising ways to do this? Thanks.

• Filtering Security Logs by User and Logon Type

  - by Trido

  I have been asked to find out when a user has logged on to the system in the last week. Now the audit logs in Windows should contain all the info I need. I think if I search for Event ID 4624 (Logon Success) with a specific AD user and Logon Type 2 (Interactive Logon) that it should give me the information I need, but for the life of my I cannot figure out how to actually filter the Event Log to get this information. Is it possible inside of the Event Viewer or do you need to use an external tool to parse it to this level? I found http://nerdsknowbest.blogspot.com.au/2013/03/filter-security-event-logs-by-user-in.html which seemed to be part of what I needed. I modified it slightly to only give me the last 7 days worth. Below is the XML I tried. <QueryList> <Query Id="0" Path="Security"> <Select Path="Security">*[System[(EventID=4624) and TimeCreated[timediff(@SystemTime) &lt;= 604800000]]]</Select> <Select Path="Security">*[EventData[Data[@Name='Logon Type']='2']]</Select> <Select Path="Security">*[EventData[Data[@Name='subjectUsername']='Domain\Username']]</Select> </Query> </QueryList> It only gave me the last 7 days, but the rest of it did not work. Can anyone assist me with this? EDIT Thanks to the suggestions of Lucky Luke I have been making progress. The below is my current query, although as I will explain it isn't returning any results. <QueryList> <Query Id="0" Path="Security"> <Select Path="Security"> *[System[(EventID='4624')] and System[TimeCreated[timediff(@SystemTime) &lt;= 604800000]] and EventData[Data[@Name='TargetUserName']='john.doe'] and EventData[Data[@Name='LogonType']='2'] ] </Select> </Query> </QueryList> As I mentioned, it wasn't returning any results so I have been messing with it a bit. I can get it to produce the results correctly until I add in the LogonType line. After that, it returns no results. Any idea why this might be? EDIT 2 I updated the LogonType line to the following: EventData[Data[@Name='LogonType'] and (Data='2' or Data='7')] This should capture Workstation Logons as well as Workstation Unlocks, but I still get nothing. I then modify it to search for other Logon Types like 3, or 8 which it finds plenty of. This leads me to believe that the query works correctly, but for some reason there are no entries in the Event Logs with Logon Type equalling 2 and this makes no sense to me. Is it possible to turn this off?

• Unable to use TweetDeck on Windows due to "Ooops, TweetDeck can't find your data" and "Sorry, Adobe

  - by Matt

  I'm running Adobe AIR 1.5.2 (latest) on Windows 7 (64-bit RTM) and downloaded TweetDeck 0.31.1 (latest). When I run TweetDeck I get the following errors: Ooops, TweetDeck can't find your data and Sorry, Adobe AIR has a problem running on this computer Other AIR applications install and run fine. I've uninstalled both TweetDeck and AIR and reinstalled. Following the uninstalls I've also removed all on-disk references to both TweetDeck and AIR, but no luck. UPDATE: Using Process Monitor I did a trace of Tweetdeck from the moment it launched until the first error occurred. I saw the following information in the output of the trace: 1 5:22:18.6522338 PM TweetDeck.exe 5580 CreateFile D:\ProgramData\Microsoft\Windows\Start Menu\Programs\rs\??\d:\Use\myusername\AppData\Roaming\Adobe\AIR\ELS\TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1\PrivateEncryptedDatak NAME INVALID Desired Access: Generic Write, Read Attributes, Disposition: OverwriteIf, Options: Synchronous IO Non-Alert, Non-Directory File, Attributes: N, ShareMode: Read, Write, AllocationSize: 0 In this trace output, Tweetdeck.exe is trying to create the file D:\ProgramData\Microsoft\Windows\Start Menu\Programs\rs\??\d:\Use\myusername\AppData\Roaming\Adobe\AIR\ELS\TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1\PrivateEncryptedDatak but the path specified is invalid. When looking at the path you can see that it is indeed an invalid path. First, there’s the “??” portion which doesn’t exist in the file system since the “?” is an invalid character in Windows/NTFS file systems. Additionally, looking at this path, it actually seems to be composed of two parts (is the "??" a delimiter?): Part 1: D:\ProgramData\Microsoft\Windows\Start Menu\Programs\rs\?? Part 2: d:\Use\myusername\AppData\Roaming\Adobe\AIR\ELS \TweetDeckFast.F9107117265DB7542C1A806C8DB837742CE14C21.1\PrivateEncryptedDatak (the problem here is that d:\Use... doesn’t even exist. What seems to be happening here is that Tweetdeck is looking for the user credentials (the “PrivateEncryptedDatak” file) but it’s looking in the wrong place, can’t find the file, and hence the error that Tweetdeck is giving (shown in the screenshot). I'm trying to determine how TweetDeck is getting this path. I searched the contents of all files on my hard disk hoping to find some TweetDeck or Adobe AIR configuration file containing this incorrect path, but I was unable to find anything. UPDATE: See Carl's comment regarding directory junctions and symbolic links under my accepted answer. This ended up being the problem. Edit by Gnoupi: People, the answer section is there to provide an actual ANSWER, not to say you have the same issue. It doesn't help anyone that you have the same problem. Eventually, if you think this is really worth mentioning, put it as a comment under the question. But simply, if what you want to add is not an answer to the question, then don't post it as an answer. This is not a forum, I recommend new users to read the FAQ: http://superuser.com/faq

• Generalized Ajax function [migrated]

  Not sure if this question will be considered "off topic". If it is, I'll remove it, but: I hadn't see this yet so I wrote it and would like to know if this is a good approach to it. Would anyone care to offer improvements to it, or point me to an example of where someone else has already written it better? function clwAjaxCall(path,method,data,asynch) { var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } if(asynch) { xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { //alert(xmlhttp.responseText); //var newaction=xmlhttp.responseText; //alert('Action becomes '+newaction); return xmlhttp.responseText; } } } if(method=='GET'){path=path+"/?"+data;} xmlhttp.open(method,path,asynch); if(method=='GET'){xmlhttp.send();}else{xmlhttp.send(data);} if (!asynch){return xmlhttp.responseText;} } I then called it like Just Testing <script type="text/javascript" src="/mypath/js/clwAjaxCall.js"></script> <script type="text/javascript"> document.write("<br>More Testing"); document.write(clwAjaxCall("http://www.mysite.com",'GET',"var=val",false)); </script>

• IIS 7.5 Manager crashes when adding a custom error page

  - by dig412

  I'm running a local IIS 7.5 server in Win 7 Pro, and I'm trying to add a custom error page for 403 responses. When I click OK to add a custom error page for my site, IIS Manager just vanishes. The server is still running, and I can re-start IIS Manager, but the new page has not been saved. I've also tried adding it directly to web.config, but that just gives me The page cannot be displayed because an internal server error has occurred. Does anyone know why this might be happening?

• Do any CDN services offer multiple urls (or aliases) for your files?

  - by Jakobud

  Lets say a company has multiple commercial web properties that happen to use a lot of the same images on each site. For SEO reasons, the sites must not appear to be related to eachother in any way. This means that the sites can't all link to the same image, even though they all use the same one. Therefore, an image is uploaded to each site and served from each site separately. In order to improve maintainability and latency, lets say the company wanted to use a CDN service. What I'm wondering is, if you upload a file, like an image or something, to a CDN, is there basically one single URL that you access that image at? Or do some (or all) CDN services offer alias URLs so that you can access the same resource from multiple URLs? Example of undesirable situation: Both sites link to the same file URL Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Example of DESIRABLE situation: Both sites link to the same file via different URLs Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-alias-path/myimage.jpg"/> So in the end, there is only one single file, myimage.jpg on the CDN server, but it is accessible from multiple URLs. Is this possible with CDN services? I know this would make browsers cache the same image twice, but at least it would be better for maintainability. Only one file would ever have to be uploaded.

• Strange strace and setuid behaviour: permission denied under strace, but not running normally.

  - by Autopulated

  This is related to this question. I have a script (fix-permissions.sh) that fixes some file permissions: #! /bin/bash sudo chown -R person:group /path/ sudo chmod -R g+rw /path/ And a small c program to run this, which is setuided: #include "sys/types.h" #include "unistd.h" int main(){ setuid(geteuid()); return system("/path/fix-permissions.sh"); } Directory: -rwsr-xr-x 1 root root 7228 Feb 19 17:33 fix-permissions -rwx--x--x 1 root root 112 Feb 19 13:38 fix-permissions.sh If I do this, everything seems fine, and the permissions do get correctly fixed: james $ sudo su someone-else someone-else $ ./fix-permissions but if I use strace, I get: someone-else $ strace ./fix-permissions /bin/bash: /path/fix-permissions.sh: Permission denied It's interesting to note that I get the same permission denied error with an identical setup (permissions, c program), but a different script, even when not using strace. Is this some kind of heureustic magic behaviour in setuid that I'm uncovering? How should I figure out what's going on? System is Ubuntu 10.04.2 LTS, Linux 2.6.32.26-kvm-i386-20101122 #1 SMP

• Problem displaying tiles using tiled map loader with SFML

  - by user1905192

  I've been searching fruitlessly for what I did wrong for the past couple of days and I was wondering if anyone here could help me. My program loads my tile map, but then crashes with an assertion error. The program breaks at this line: spacing = atoi(tilesetElement-Attribute("spacing")); Here's my main game.cpp file. #include "stdafx.h" #include "Game.h" #include "Ball.h" #include "level.h" using namespace std; Game::Game() { gameState=NotStarted; ball.setPosition(500,500); level.LoadFromFile("meow.tmx"); } void Game::Start() { if (gameState==NotStarted) { window.create(sf::VideoMode(1024,768,320),"game"); view.reset(sf::FloatRect(0,0,1000,1000));//ball drawn at 500,500 level.SetDrawingBounds(sf::FloatRect(view.getCenter().x-view.getSize().x/2,view.getCenter().y-view.getSize().y/2,view.getSize().x, view.getSize().y)); window.setView(view); gameState=Playing; } while(gameState!=Exiting) { GameLoop(); } window.close(); } void Game::GameLoop() { sf::Event CurrentEvent; window.pollEvent(CurrentEvent); switch(gameState) { case Playing: { window.clear(sf::Color::White); window.setView(view); if (CurrentEvent.type==sf::Event::Closed) { gameState=Exiting; } if ( !ball.IsFalling() &&!ball.IsJumping() &&sf::Keyboard::isKeyPressed(sf::Keyboard::Space)) { ball.setJState(); } ball.Update(view); level.Draw(window); ball.Draw(window); window.display(); break; } } } And here's the file where the error happens: /********************************************************************* Quinn Schwab 16/08/2010 SFML Tiled Map Loader The zlib license has been used to make this software fully compatible with SFML.

• FreeType2 Crash on FT_Init_FreeType

  - by JoeyDewd

  I'm currently trying to learn how to use the FreeType2 library for drawing fonts with OpenGL. However, when I start the program it immediately crashes with the following error: "(Can't correctly start the application (0xc000007b))" Commenting the FT_Init_FreeType removes the error and my game starts just fine. I'm wondering if it's my code or has something to do with loading the dll file. My code: #include "SpaceGame.h" #include <ft2build.h> #include FT_FREETYPE_H //Freetype test FT_Library library; Game::Game(int Width, int Height) { //Freetype FT_Error error = FT_Init_FreeType(&library); if(error) { cout << "Error occured during FT initialisation" << endl; } And my current use of the FreeType2 files. Inside my bin folder (where debug .exe is located) is: freetype6.dll, libfreetype.dll.a, libfreetype-6.dll. In Code::Blocks, I've linked to the lib and include folder of the FreeType 2.3.5.1 version. And included a compiler flag: -lfreetype My program starts perfectly fine if I comment out the FT_Init function which means the includes, and library files should be fine. I can't find a solution to my problem and google isn't helping me so any help would be greatly appreciated.

• How do I make Nginx redirect all requests for files which do not exist to a single php file?

  - by Richard

  I have the following nginx vhost config: server { listen 80 default_server; access_log /path/to/site/dir/logs/access.log; error_log /path/to/site/dir/logs/error.log; root /path/to/site/dir/webroot; index index.php index.html; try_files $uri /index.php; location ~ \.php$ { if (!-f $request_filename) { return 404; } fastcgi_pass localhost:9000; fastcgi_param SCRIPT_FILENAME /path/to/site/dir/webroot$fastcgi_script_name; include /path/to/nginx/conf/fastcgi_params; } } I want to redirect all requests that don't match files which exist to index.php. This works fine for most URIs at the moment, for example: example.com/asd example.com/asd/123/1.txt Neither of asd or asd/123/1.txt exist so they get redirected to index.php and that works fine. However, if I put in the url example.com/asd.php, it tries to look for asd.php and when it can't find it, it returns 404 instead of sending the request to index.php. Is there a way to get asd.php to be also sent to index.php if asd.php doesn't exist?

• nginx: SSI working on Apache backend, but not on gunicorn backend

  - by j0nes

  I have nginx in front of an Apache server and a gunicorn server for different parts of my website. I am using the SSI module in nginx to display a snippet in every page. The websites include a snippet in this form: For static pages served by nginx everything is working fine, the same goes for the Apache-generated pages - the SSI include is evaluated and the snippet is filled. However for requests to my gunicorn backend running a Python app in Django, the SSI include does not get evaluated. Here is the relevant part of the nginx config: location /cgi-bin/script.pl { ssi on; proxy_pass http://default_backend/cgi-bin/script.pl; include sites-available/aspects/proxy-default.conf; } location /directory/ { ssi on; limit_req zone=directory nodelay burst=3; proxy_pass http://django_backend/directory/; include sites-available/aspects/proxy-default.conf; } Backends: upstream django_backend { server dynamic.mydomain.com:8000 max_fails=5 fail_timeout=10s; } upstream default_backend { server dynamic.mydomain.com:80; server dynamic2.mydomain.com:80; } proxy_default.conf: proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; What is the cause for this behaviour? How can I get SSI includes working for my pages generated on gunicorn? How can I debug this further?
