• How do I know if I am using Scrum methodologies?

  - by Jake

  When I first started at my current job, my purpose was to rewrite a massive excel-VBA workbook-application to C# Winforms because it was thought that the new C# app will fix all existing problems and have all the new features for a perfect world. If it were a direct port, in theory it would be easy as i just need to go through all the formulas, conditional formatting, validations, VBA etc. to understand it. However, that was not the case. Many of the new features are tightly dependant on business logic which I am unfamiliar with. As a solo programmer, the first year was spent solely on deciphering the excel workbook and writing the C# app. In theory, I had the business people to "help" me specify requirements, how GUI looks and work, and testing of the app etc; but in practice it is like a contant tsunami of feature creep. At the beginning of the second year I managed to convince the management that this is not going anywhere. I made them start from scratch with the excel-VBA. I have this "issue log" saved on the network, each time they found something they didn't like about the excel-VBA app, they will write it in there. I check the log daily and consolidate issues (in my mind) mainly into 2 groups: (1) requires massive change. (2) can be fixed in current version. For massive change issues, I make a copy of the latest excel-VBA and give it a new version number, then work on it whenever I can. For current version fixes, I make the changes in a few days to a week, and then immediately release it. I also ensure I update the same change in any in-progress massive change future versions. This has gone on for about 4 months and I feel it works great. I made many releases and solved many real issues, also understood the business logic more and more. However, my boss (non-IT trained) thinks what I am doing are just adhoc changes and that i am not looking at the "bigger picture". I am struggling to convince my boss that this works. So I hope to formalise my approach and maybe borrow a buzzword to confuse him. Incidentally, I read about Agile and SCRUM, about backlog and sprints. But it's all very vague to me still. QUESTION (finally): I want to tell him that this is SCRUM! But I want to hold my breath first and ask whether my current approach is considered SCRUM or SCRUM-like? How can I make it more SCRUM-like? Note that I have only myself, there's no project leader or teams.

• How to be successful at BDD Specifications Workshops?

  - by sigo

  Today we tried to introduce BDD in our software development process by having a specification workshop. For this workshop we had 2 developers, 1 tester and 1 business analyst. The workshop lasted 1h30 and by the end of it we managed to figure out some BDD scenarios for our new feature. We tried to focus on finding the scenarios that we could miss, and the difficult ones. At the end of the workshop some people were actually unhappy with the workshop. One developer felt he wasted his time as he was used to be given out the scenarios directly by the business analyst and review them with her. The business analyst didn't feel confident with our scenario coverage (Had a feeling that we could have missed out other important stuff) but more importantly felt that this workshop was also a waste of time as she could have figured out all these scenarios by herself and in a shorter period of time. So my question is how that kind of workshop can actually work. In the theory, given you have a new feature to develop, you put the tree 'amigos' (dev/tester/ba) in the same room so that they can collaborate together on writing the differents requirements for the new feature using examples. I can see all the benefits from that. Specially in term of knowledge sharing and common product/end goal/done vision. But in practice, we still think it is more cost effective to first have a BA to work on his own on the examples and only then to have the scenarios to be reviewed/reworked by the 3 'amigos'. By having the BA to work on his own, we actually feel more confident that we are less going to miss out stuff + we still get to review the scenarios afterward to double check. We don't think than simple brainstorming/deliberate discovery is actually enought to seriously cover all the requirement for a feature. The business analyst is actually the best person for that kind of stuff. The thing we just do is to review what she wrote and see if then we have a common understanding (which could then lead to rewrite some of her scenarios or add new ones she could have missed). This workshop lasted 1h30, and by the end of it, we didn't feel confident enought about wha we did...sure we could have spent more time on it but honestly most people get exhausted after 1h30 of brainstorming. So how can you get that to work effectively in practice ?

• Keep coding the wrong way to remain consistent? [closed]

  - by bwalk2895

  Possible Duplicate: Code maintenance: keeping a bad pattern when extending new code for being consistent, or not? To keep things simple let's say I am responsible for maintaining two applications, AwesomeApp and BadApp (I am responsible for more and no that is not their actual names). AwesomeApp is a greenfield project I have been working on with other members on my team. It was coded using all the fancy buzzwords, Multilayer, SOA, SOLID, TDD, and so on. It represents the direction we want to go as a team. BadApp is a application that has been around for a long time. The architecture suffers from many sins, namely everything is tightly coupled together and it is not uncommon to get a circular dependency error from the compiler, it is almost impossible to unit test, large classes, duplicate code, and so on. We have a plan to rewrite the application following the standards established by AwesomeApp, but that won't happen for a while. I have to go into BadApp and fix a bug, but after spending months coding what I consider correctly, I really don't want do continue perpetuate bad coding practices. However, the way AwesomeApp is coded is vastly different from the way BadApp is coded. I fear implementing the "correct" way would cause confusion for other developers who have to maintain the application. Question: Is it better to keep coding the wrong way to remain consistent with the rest of the code in the application (knowing it will be replaced) or is it better to code the right way with an understanding it could cause confusion because it is so much different? To give you an example. There is a large class (1000+ lines) with several functions. One of the functions is to calculate a date based on an enumerated value. Currently the function handles all the various calculations. The function relies on no other functionality within the class. It is self contained. I want to break the function into smaller functions (at the very least) and put them into their own classes and hide those classes behind an interface (at the most) and use the factory pattern to instantiate the date classes. If I just broke it out into smaller functions within the class it would follow the existing coding standard. The extra steps are to start following some of the SOLID principles.

• core.* files eating up server space (~50MB)

  - by skytreader

  I'm renting server space from someone and, upon logging in my control panel after quite sometime, noticed an abnormal spike (~50MB) in the disk usage. Upon investigating, I found a lot of core.* files scattered around my public_html directory. Each one is more than 5MB in size but no more than 6MB. The * part is all numbers (in programming regex, that should be core\.\d+). I downloaded one and checked the contents. There was a lot of balderdash characters (NUL mostly, but also a scattering of ETB, ETX, STX) but there's this block of readable text which says: This text is part of the internal format of your mail folder, and is not a real message. It is created automatically by the mail system software. If deleted, important folder data will be lost, and it will be re-created with the data reset to initial values. Pretty self-explanatory. A few blocks above the text are some more readable messages that look like logs but is sandwiched in between non printable characters. I've extracted some below. Scan not valid for mh mailboxes Bogus character 0x%x in news state Can't rewrite news state %.80s Error closing backup news state %.80s No state for newsgroup %.80s found Now, a few concerns: Am I under attack? The messages seem to be about my webmail but I don't use my personal webmail that much---only for a vanity email address and an inbox for an outdated comments system. However, lately, I seem to notice a spike in the spam for my vanity mail. (Note: the comments system is covered by a captcha but every now and then some get through. My vanity email has a spam filter but it isn't as good as I'd like). Next, if this is a feature, can I turn it off? Is it advisable to? I've only 150MB so you see why I'm fretting over a 50MB spike. Some final details: my only server-side scripts are in PHP. The directory which accumulated the most number of these core files is the one containing the Wordpress-managed subdomain of my site. I manage my server through CPanel. Lastly, I decided to delete this files and after some checking nothing seems amiss in my websites nor in my mail. They are indeed the ones responsible for the ~50MB spike as my disk space usage is back to expected.

• How / Where can I host my Java web application? [closed]

  - by Huliax

  Possible Duplicate: How to find web hosting that meets my requirements? In case you want to skip to the crux of my inquiry just read the bold type. I just finished my CS degree (at 39 years old :-)). For my final project I designed and built a system that can provide local positioning / location awareness to mobile wifi devices (only have Android client thus far). The server receives data from clients, processes it, and responds to the clients with a messages containing information about their respective locations. I would like to continue the project (perhaps release as open source but that is a different discussion). Thus far my server application has been running on the CS department's hardware where I could pretty much do whatever I wanted. I'm getting kicked off that system in a few weeks so I have to find a new home for my server application. I need a host that will let me run my Java server (along w/ mySQL db) -- preferably on the cheap since I haven't yet got a job. I have very little experience with the "real world" of web development / hosting. I'm having trouble figuring out what kind of hosting service will let me run my application as is. If that turns out to be a tall order then I need to know what my options are for changing thing so that I can get up and running with some hosting. As an aside, I'm also researching whether or not I should rewrite this in a different language. Trying to figure out if there is a substantially better (for whatever reason) one for what I'm doing. This might also potentially have a bearing on my hosting needs. One possibility is to write the server in something more widely accepted by hosting services. I have been searching for answers to my question and haven't found quite what I'm looking for. Part of the problem might be that I don't know exactly what terminology to use. If there is a good answer to this question elsewhere please feel free to point me towards it. Thanks for help / advice.

• How to cleanly add after-the-fact commits from the same feature into git tree

  - by Dennis

  I am one of two developers on a system. I make most of the commits at this time period. My current git workflow is as such: there is master branch only (no develop/release) I make a new branch when I want to do a feature, do lots of commits, and then when I'm done, I merge that branch back into master, and usually push it to remote. ...except, I am usually not done. I often come back to alter one thing or another and every time I think it is done, but it can be 3-4 commits before I am really done and move onto something else. Problem The problem I have now is that .. my feature branch tree is merged and pushed into master and remote master, and then I realize that I am not really done with that feature, as in I have finishing touches I want to add, where finishing touches may be cosmetic only, or may be significant, but they still belong to that one feature I just worked on. What I do now Currently, when I have extra after-the-fact commits like this, I solve this problem by rolling back my merge, and re-merging my feature branch into master with my new commits, and I do that so that git tree looks clean. One clean feature branch branched out of master and merged back into it. I then push --force my changes to origin, since my origin doesn't see much traffic at the moment, so I can almost count that things will be safe, or I can even talk to other dev if I have to coordinate. But I know it is not a good way to do this in general, as it rewrites what others may have already pulled, causing potential issues. And it did happen even with my dev, where git had to do an extra weird merge when our trees diverged. Other ways to solve this which I deem to be not so great Next best way is to just make those extra commits to the master branch directly, be it fast-forward merge, or not. It doesn't make the tree look as pretty as in my current way I'm solving this, but then it's not rewriting history. Yet another way is to wait. Maybe wait 24 hours and not push things to origin. That way I can rewrite things as I see fit. The con of this approach is time wasted waiting, when people may be waiting for a fix now. Yet another way is to make a "new" feature branch every time I realize I need to fix something extra. I may end up with things like feature-branch feature-branch-html-fix, feature-branch-checkbox-fix, and so on, kind of polluting the git tree somewhat. Is there a way to manage what I am trying to do without the drawbacks I described? I'm going for clean-looking history here, but maybe I need to drop this goal, if technically it is not a possibility.

• Best language on Linux to replace manual tasks that use SSH/Telnet? [on hold]

  - by Calab

  I've been tasked to create and maintain a web browser based interface to replace several of the manual tasks that we perform now. I currently have a "shakey" but working program written in Perl (2779 lines) that uses basic Expect coding, but it has some limitations that require a great deal of coding to get around. Because of this I am going to do a complete rewrite and want to do it "right" this time. My question is this... What would be the best language to use to create a web based interface to perform SSH/Telnet tasks that we would normally do manually? Keep in mind the following requirements: Runs on a CentOS Linux system v5.10 Http will be served by Apache2 This is an INTRANET site and only accessible within our organization. User load will be light. No more that 5 users accessing it at one time. perl 5.8.8, php 5.3.3, python 2.7.2 are available... Not sure what other languages to check for, or what modules might be installed in each language. The web interface will need to provide progress indicators and text output produced by the remote connection, in real time as it is generated. If we are running our process on multiple hosts, they should be in individual threads so that they can run side by side, not sequentially. I want the ability to "trap" on specific text generated by the remote host and display an alert to the user - such as when the remote host generates an error message. I would like to avoid as much client side scripting (javascript/vbscript) as I can. Most users will be on Windows PC's using Chrome or IE as a browser. Users will be downloading the resulting output so they can process it as they see fit. I currently have no experience with "Ajax" or the like. Most of my coding experience is old 6809 assembly, Visual Basic 6, and whatever I can cut/paste from online examples in various languages (hence my "shaky" Perl program) My coding environment is Eclipse for remote code editing, but I prefer stuff like UltraEdit if I can get a decent syntax file for the language I'm using. I do have su access on the server, but I'm not the only one using this server so I can't just upgrade/install blindly as I might impact other software currently running on the machine. One reason that I'm asking here, instead of searching (which I did) is that most replies were, "use language 'xyz', but you need to use an external SSH connection" - like I'm using Expect in my Perl script. Most also did not agree on what language that 'xyz' should be. ...so, after this long posting, can someone offer some advice?

• Mounting an Azure blob container in a Linux VM Role

  - by djechelon

  I previously asked a question about this topic but now I prefer to rewrite it from scratch because I was very confused back then. I currently have a Linux XS VM Role in Azure. I basically want to create a self-managed and evoluted hosting service using VMs rather than Azure's more-expensive Web Roles. I also want to take advantage of load balancing (between VM Roles) and geo-replication (of Storage Roles), making sure that the "web files" of customers are located in a defined and manageable place. One way I found to "mount" a drive in Linux VM is described here and involves mounting a VHD onto the virtual machine. From what I could learn, the VHD is reliably-stored in a storage role, and is exclusively locked by the VM that uses it. Once the VM Role has its drive I can format the partition to any size I want. I don't want that!! I would like each hosted site to have its own blob directory, then each replicated/load-balanced VM Role to rw mount like in NFS that blob directory to read HTML and script files. The database is obviously courtesy of Microsoft :) My question is Is it possible to actually mount a blob storage into a directory in the Linux FS? Is it possible in Windows Server 2008?

• Nginx unknown limit_req_zone

  - by Kayle

  Nginx currently will not start due to the error mentioned in the title. Here's the actual error I'm getting: $ sudo /etc/init.d/nginx restart Restarting nginx: nginx: [emerg] unknown limit_req_zone "one" in /etc/nginx/sites-enabled/www.myhashimotosthyroiditis.com:15 nginx: configuration file /etc/nginx/nginx.conf test failed And this is immediately following creating the VM in question (www.myhashimotosthyroiditis.com), using a template I found here that was supposedly the "out-of-the-box-for-lazy-people" templates. I'm very new to Nginx and I could not find any helpful information via google or searching here, so I beg my pardon if this is a product of stupidity. Here is the entirety of the VM file: server { listen 80; server_name myhashimotosthyroiditis.com www.myhashimotosthyroiditis.com; root /var/www/myhashimotosthyroiditis; access_log /var/log/nginx/myhashimotosthyroiditis.access.log; error_log /var/log/nginx/myhashimotosthyroiditis.error.log; location / { try_files $uri $uri/ /index.php; } location /search { limit_req zone=one burst=3 nodelay; rewrite ^ /index.php; } fastcgi_intercept_errors off; location ~* \.(?:ico|css|js|gif|jpe?g|png)$ { expires max; add_header Pragma public; add_header Cache-Control "public, must-revalidate, proxy-revalidate"; } include php.conf; # You may want to remove the robots line from drop to use a virtual robots.txt # or create a drop_wp.conf tailored to the needs of the wordpress configuration include drop.conf; }

• saslauthd + PostFix producing password verification and authentication errors

  - by Aram Papazian

  So I'm trying to setup PostFix while using SASL (Cyrus variety preferred, I was using dovecot earlier but I'm switching from dovecot to courier so I want to use cyrus instead of dovecot) but I seem to be having issues. Here are the errors I'm receiving: ==> mail.log <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure ==> mail.info <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure ==> mail.warn <== Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: SASL authentication failure: Password verification failed Aug 10 05:11:49 crazyinsanoman postfix/smtpd[779]: warning: ipname[xx.xx.xx.xx]: SASL PLAIN authentication failed: authentication failure I tried $testsaslauthd -u xxxx -p xxxx 0: OK "Success."

• IIS6 Wildcard Mapping to ASP.NET - no file extension results in IIS 404

  - by Ian Robinson

  I'm trying to perform what I understand to be a relatively simple task. I'd like to remove the extensions from the URLs on my website. I have the proper set up in my application to handle and rewrite the URLs - the trouble is I can't get past IIS to actually get to my application without the extensions. The details: I'm running IIS6 on Windows Server 2003. I've gone into the web site for my application, gone to the home directory tab, clicked "Configuration" and added a wildcard map to the following file: c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll Which I verified is the same as what is used above in the application extensions portion by .ascx, etc. If I navigate to http://mywebsite.com/Blogs the result is as follows: HTTP/1.1 404 Not Found Content-Length: 1635 Content-Type: text/html Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET Date: Thu, 14 Jan 2010 15:04:49 GMT Which seems to be a standard IIS 404 message. If I navigate to http://mywebsite.com/Blogs.aspx I get my ASP.NET app.... How can I troubleshoot this? I feel like I've double checked everything a dozen times but to no avail. I must be missing something obvious. Update: Here are the exact instructions given by the asp.net url rewriter that I'm using: IIS 6.0 - Windows 2003 Server open property page for website / virtual directory. click the 'home directory' tab click the 'configuration' button, select the 'mappings' tab click 'insert' next to the 'Wildcard application maps' section browse to the aspnet_isapi.dll (normally at c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll) Ensure that 'check that file exists' is unchecked Click OK, OK, OK to close and apply changes Update 2: I have yet to find a resolution for this. The application does not seem to be receiving the request from IIS, any further ideas?

• Crazy problem with Nginx, PHP5-FPM on Ubuntu

  - by Emmanuel

  I've been trying to get a domain from shared hosting to my new VPS. Everything was working just 100% fine, and then all of a sudden rewrites stopped working, pictures that should work started returning 404s. I've got no idea why, but for some reason on my site: http://www.onlythebible.com/ only the home page works, all the other pages depend on rewrites which were working perfectly fine at one stage, but all of a sudden stopped working. Some of the pictures like this url: http://www.onlythebible.com/bgsPreview/Matthew-8.10.jpg which doesn't use a rewrite throws a 404? I almost certain it was nothing to do with the nginx configuration. I've got suspicions that it could be something to do with php5-fpm? The funny thing is, all of a sudden it started working again. And then an hour or so later it broke again and has now gone back to only displaying the home-page and all of the links (and some of the pictures) are just showing 404s. Does anyone have an idea of what the problem might be? I'm pretty new to the whole Linux VPS thing, but this just seems very strange. *edit Here's a line from the error log which might shed some light on the problem: 2011/02/06 03:04:59 [error] 2873#0: *220 open() "/usr/local/nginx/html/bgsPreview/Matthew-8.10.jpg" failed (2: No such file or directory), client: 114.77.115.211, server: onlythebible.com, request: "GET /bgsPreview/Matthew-8.10.jpg HTTP/1.1", host: "www.onlythebible.com", referrer: "http://www.onlythebible.com/" I wonder why it's trying to find the file in /usr/local/nginx/html instead of the proper root which is /var/www/ etc... Oh, and for some reason it's just started working again... for how long I don't know. Another thing that was a bit weird, is that the pages on my website are pulled from a database. But when I edited the database, the pages didn't change... It's almost like they've been cached or something.

• nginx subdomains improperly act like wildcard?

  - by binjured

  I have an odd problem with nginx subdomains. First, my configuration: server { listen 443 ssl; server_name secure.example.com; ssl_certificate example.crt; ssl_certificate_key example.key; keepalive_timeout 70; location / { fastcgi_pass 127.0.0.1:8000; ... } } server { listen 80; server_name example.com www.example.com; location / { fastcgi_pass 127.0.0.1:8000; ... } } The idea being that I have a secure domain, secure.example.com and a normal domain, example.com. In practice, I can go to https://example.com and http://secure.example.com. I worked around the second issue with an intermediary server: server { listen 80; server_name secure.example.com; rewrite ^(.*) https://secure.example.com$1 permanent; } But this is not an optimal solution and I'd have to create another one to redirect https on the tld to the subdomain. I feel like I must be doing something wrong if I need multiple servers like that. Why does https://example.com work when there is no server listening on 443 there? Shouldn't it just fail to connect? I'm rather confused.

• SSI includes not working on Debian with Apache

  - by Mike

  I'm trying to get SSI to work on Debian running Apache, however the .shtml files are not being parsed. From a PHP file with phpinfo() I can see that the following show up in the loaded modules section: mod_mime_xattr mod_mime mod_mime_magic In /etc/apache2/mods-enabled/mime.conf I have (among other things): AddType text/html .shtml AddOutputFilter INCLUDES .shtml In /etc/apache2/sites-enabled/domain.com.conf (for the virtual host in question) I have: <Directory /home/username/public_html> Options +Includes allow from all AllowOverride All </Directory> and for good measure, I added the following as well: <Directory /> Options +Includes </directory> In the user's .htaccess file, I tried adding: Options +Includes AddType text/html shtml AddHandler server-parsed shtml Nothing seems to work. How can I even debug this?

• IPCop Packet Mangling

  - by Zenham

  I've found myself in a pickle replacing an old firewall for a client this afternoon. I'm configuring their new IPCop firewall (1.4.21), Zerina OpenVPN addon is installed. What I need to do: There are three network interfaces, currently set up as red (WAN), green (LAN, 192.168.20.0/24) and orange (remote network 10.1.20.0/24). The orange interface is a direct fiber link to another organization. Simple description: Traffic and networks appear to be properly configured at this point, but I have many (150+) specific IPs on the LAN which, when accessing the resources on the 10.1.20.x network, need to be mangled to appear to be coming from the 10.1.20.0/24 network (and return traffic properly delivered). The routing on the far side was configured earlier and should be fine, but I need to redirect any packets coming across destined for those IPs to end up at their proper destination. The addressing is fixed and predictable (ie. 192.168.20.125 - 10.1.20.125). I need to insert whatever rules I have into the IPCop ruleset through /etc/rc.local I know, I'm just not sure about how I should structure this. There's CUSTOMOUTPUT and CUSTOMINPUT targets, both which currently just consist of the single rule redirecting packets to the OVPNOUTPUT/OVPNINPUT targets, so I'm guessing I should insert a rule matching outbound packets destined for the 10.1.20.x network and redirecting to a new target (maybe called TO-ORANGE) and a rule at the top of CUSTOMINPUT which redirects to a FROM-ORANGE target. Under those targets, I would have rules which do the IP matching and mangling. Am I approaching this right? If so, I'm not very familiar with mangle, and would appreciate seeing examples of how to write that source-IP rewrite. If not, how would you suggest doing this? TIA! edit: I notice additionally that the nat table has CUSTOMPREROUTING and CUSTOMPOSTROUTING targets, I guess I could alternatively post the rules in there....

• Unable to receive any emails using postfix, dovecot, mysql, and virtual domain/mailboxes

  - by stkdev248

  I have been working on configuring my mail server for the last couple of weeks using postfix, dovecot, and mysql. I have one virtual domain and a few virtual mailboxes. Using squirrelmail I have been able to log into my accounts and send emails out (e.g. I can send to googlemail just fine), however I am not able to receive any emails--not from the outside world nor from within my own network. I am able to telnet in using localhost, my private ip, and my public ip on port 25 without any problems (I've tried it from the server itself and from another computer on my network). This is what I get in my logs when I send an email from my googlemail account to my mail server: mail.log Apr 14 07:36:06 server1 postfix/qmgr[1721]: BE01B520538: from=, size=733, nrcpt=1 (queue active) Apr 14 07:36:06 server1 postfix/pipe[3371]: 78BC0520510: to=, relay=dovecot, delay=45421, delays=45421/0/0/0.13, dsn=4.3.0, status=deferred (temporary failure.

• mod_wsgi, .htaccess and rewriterule

  - by hadaraz

  I'm using several django projects running on the same apache instance through mod_wsgi, configured with virtualhost for each site, see the httpd.conf here. For one of the sites I want to use static-cache (staticgenerator), so I set up a directory with .htaccess file which contains: RequestHeader unset X-Forwarded-Host RewriteEngine on RewriteBase / RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}/index.html !-f RewriteRule ^(.*) http://127.0.0.1:3456/$1 [P] where 3456 is the django port on the server. Using this rewrite rule, the request is always forwarded to the mod_wsgi handler, even if the file or directory exists, and if the file index.html exists the request shows as request-path/index.html. I tried another setup: RequestHeader unset X-Forwarded-Host RewriteEngine on RewriteBase / RewriteCond $1 !-d RewriteCond $1index.html !-f RewriteRule ^(.*) http://127.0.0.1:3456/$1 [P] but got almost the same results. All requests are transferred to the mod_wsgi handler, but the request path is now the original one. To sum it up: What is the correct RewriteCond to use here? How do you transfer a request to the mod_wsgi handler? Is it the right way? If that's not the way to do it, then how do you serve static files from a directory when they exist, and when they don't you serve from apache/mode_wsgi? Thanks for your help.

• How to specify search domain name of nginx resolver for proxy_pass

  - by myjpa

  Assuming my server is www.mydomain.com, on Nginx 1.0.6 I'm trying to proxy all request to http://www.mydomain.com/fetch to other hosts, the destination URL is specified as a GET parameter named "url". For instance, when user requests either one: http://www.mydomain.com/fetch?url=http://another-server.mydomain.com/foo/bar http://www.mydomain.com/fetch?url=http://another-server/foo/bar it should be proxyed to http://another-server.mydomain.com/foo/bar I'm using the following nginx config and it works fine only if the url paramter contains domain name, like http://another-server.mydomain.com/...; but fails on http://another-server/... on error: another-server could not be resolved (3: Host not found) nginx.conf is: http { ... # the DNS server resolver 171.10.129.16; server { listen 80; server_name localhost; root /path/to/site/root; location = /fetch { proxy_pass $arg_url; } } Here, I'd like to resolve all URL without domain name as host name in mydomain.com, in /etc/resolv.conf, it's possible to specify default search domain name for the whole Linux system, but it doesn't affect nginx resolver: search mydomain.com Is it possible in Nginx? Or alternatively, how to "rewrite" the url parameter so that I can add the domain name?

• Apache 2.2, worker mpm, mod_fcgid and PHP: Can't apply process slot

  - by mopoke

  We're having an issue on an apache server where every 15 to 20 minutes it stops serving PHP requests entirely. On occasions it will return a 503 error, other times it will recover enough to serve the page but only after a delay of a minute or more. Static content is still served during that time. In the log file, there's errors reported along the lines of: [Wed Sep 28 10:45:39 2011] [warn] mod_fcgid: can't apply process slot for /xxx/ajaxfolder/ajax_features.php [Wed Sep 28 10:45:41 2011] [warn] mod_fcgid: can't apply process slot for /xxx/statics/poll/index.php [Wed Sep 28 10:45:45 2011] [warn] mod_fcgid: can't apply process slot for /xxx/index.php [Wed Sep 28 10:45:45 2011] [warn] mod_fcgid: can't apply process slot for /xxx/index.php There is RAM free and, indeed, it seems that more php processes get spawned. /server-status shows lots of threads in the "W" state as well as some FastCGI processes in "Exiting(communication error)" state. I rebuilt mod_fcgid from source as the packaged version was quite old. It's using current stable version (2.3.6) of mod_fcgid.

  I am using Debian squeeze with nginx and mysql. After raking db and loading default data to redmine.

• Swap space maxing out - JVM dying

  - by travega

  I have a server running 3 WordPress instances, MySql, Apache and the play framework 2.0 on 64m initial & max heap. If I increase the max heap of the JVM that play is running in even by 16m I see the 128m of swap space steadily fill up until the the JVM dies. I notice that it is only when I am plugging away at the wordpress sites that the JVM will die. I assume this is because the JVM is not asking for memory at the time so gets collected. I notice that when I restart Apache I reclaim about half of my swap and RAM. So is there some way I can configure apache to consume less memory? Also what could be causing the swap space to get so heavily thrashed with just 16m added to the max heap size of the JVM?

• Lock down Wiki access to password only but remain open to a subnet via .htaccess

  - by Treffynnon

  Basically we have a Wiki that has some sensitive information stored in it - not the best I know but my predecessor set it up. I want to be able to request password access from any one who is not on the local network subnet. Those on the local subnet should be able to proceed without entering a password. The following .htaccess does not seem to work any more as it is letting non-local access without requiring the password: AuthName "Our Wiki" AuthType Basic AuthUserFile /path/to/passwd/file AuthGroupFile /dev/null Require valid-user Allow from 192.168 Satisfy Any order deny,allow And I cannot work out why. The WikkaWiki it is supposed to be protecting was recently upgraded, which clobbered the .htaccess file so I restored the above from memory/googling. Maybe I am missing an important directive? The full .htaccess is as follows: AuthName "Our Wiki" AuthType Basic AuthUserFile /path/to/passwd/file AuthGroupFile /dev/null Require valid-user Allow from 192.168 Satisfy Any SetEnvIfNoCase Referer ".*($LIST_OF_ADULT_WORDS).*" BadReferrer order deny,allow deny from env=BadReferrer <IfModule mod_rewrite.c> # turn on rewrite engine RewriteEngine on RewriteBase / # if request is a directory, make sure it ends with a slash RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^(.*/[^/]+)$ $1/ # if not rewritten before, AND requested file is wikka.php # turn request into a query for a default (unspecified) page RewriteCond %{QUERY_STRING} !wakka= RewriteCond %{REQUEST_FILENAME} wikka.php RewriteRule ^(.*)$ wikka.php?wakka= [QSA,L] # if not rewritten before, AND requested file is a page name # turn request into a query for that page name for wikka.php RewriteCond %{QUERY_STRING} !wakka= RewriteRule ^(.*)$ wikka.php?wakka=$1 [QSA,L] </IfModule>
