• is there a man in the middle attacking to my server machine?

  - by GongT

  My server works well about half a year. But a strange thing happened (several hours before). This server has two IP-address 58.17.85.19 & 117.21.178.19 When I navigate to http://58.17.85.19, nothing different as before. But http://117.21.178.19 will return a "302 Object moved" and become a "redirect loop" I do some test: ($cmd = "wget http://117.21.178.19/?xx=$RANDOM --max-redirect 0 -S --no-cache -O -") Step by step: run $cmd on my PC and my firend's one (we live in two side of China, far away). - got 302 run $cmd on this server - got 200 OK (content is correct result of index.php) run $cmd on another server in same computer room - got 200 OK telnet from my PC and build an HTTP request (type by hand) - got 200 OK shutdown php-fpm, run $cmd on my PC - got 302 run $cmd on server - 502 Bad Gateway shutdown nginx, run $cmd on both the server and my PC - Connection refused. create iptables rule, refuse any connection to 58.17.85.19:80. run nc -l 80 -k -vvv on server and run $cmd on my PC NC show me that.... Server accept connection (Connection from [my ip]) My connection closed ! (Remove fd xx from list) wget dump out response - got 302 I know that, normaly, NC will accept connection, then dump HTTP request from client, and client will wait for response. this connection will open forever(infact client will close connection becouse timeout), becouse NC can't give any response. So... where my request gone? who send an response to the client? some virus on my server system? If so, why 58.17.85.19 didn't has this error? or... I was attacked by a middleman?

• Exim, hot to route local mail to other adress

  - by kheraud

  I have setuped an Exim4 server on my debian wheezy server. This mail server only sends mail coming from localhost. The purpose is sending mail for my website. I have cron tasks and other services generating mails for root user. These mails are not stored in /var/mail as before, but sent by exim to [email protected]. I try to make exim send mails for root to [email protected] rather than [email protected]. I tried adding a .forward in /root with [email protected] as content. I tried also changing /etc/aliases with root: [email protected]. The fact is that routing works for root@localhost but not for root which is resolved as [email protected] I tested how routing is resolved with exim -bt : root@srv02:~# exim -bt root@localhost R: system_aliases for root@localhost R: dnslookup for [email protected] [email protected] <-- root@localhost router = dnslookup, transport = remote_smtp host gmail-smtp-in.l.google.com [173.194.67.27] MX=5 host alt1.gmail-smtp-in.l.google.com [74.125.143.27] MX=10 host alt2.gmail-smtp-in.l.google.com [74.125.25.27] MX=20 host alt3.gmail-smtp-in.l.google.com [173.194.64.27] MX=30 host alt4.gmail-smtp-in.l.google.com [74.125.142.27] MX=40 root@srv02:~# exim -bt root R: dnslookup for [email protected] [email protected] router = dnslookup, transport = remote_smtp host aspmx.l.google.com [173.194.78.27] MX=1 host alt1.aspmx.l.google.com [74.125.143.27] MX=5 host alt2.aspmx.l.google.com [74.125.25.27] MX=5 host alt4.aspmx.l.google.com [74.125.142.27] MX=10 host alt3.aspmx.l.google.com [173.194.64.27] MX=10 I bet this is a matter of how my server is configured (rather than how exim is configured). But to understand well I would like to have a solution for both : how to have root resolved as root@localhost ? how to have [email protected] routed to [email protected] ?

• Why does lighttpd keep static files in cache, even when modified on disk ?

  - by Pixelastic

  I am using lighttpd to serve static files. I have a bunch of images in a dir that I regularly update. This will change the file content (and filesize) as well as the modification date, but not their filename. When I access the files through http, the updates are not taken into account and lighty serves the old file. I can manually rename the file to something different, then lighttpd will return a 404 error, and if I rename my file back, I will get the correct updated version. Seems like lightty is using some kind of cache mechanism of its own (which is fine) to return static files. Unfortunatly, it seems that this mechanism doesn't update itself when files are modified. I checked through Wireshark, and my browser is really doing a request to the file, this is not a browser caching issue. It returns a 200 OK when requesting it from an empty cache, and a 304 Not Modified otherwise, as expected. But the file is returned with a wrong Last-Modified header that do not reflect the real last modification date. Maybe there is some config directive that I am not aware of ? I would like the files returned by lighty to reflect the changes made on disk directly, or at least being able to invalidate its cache.

• Portforwarding Combine Several Ports

  - by kiraitachi

  Hi I got a Raspberry Pi at A.A.A.B in my local network and I have set up a DMZ on my router so that any incoming traffic that comes to my router gets redirected to my raspberry pi wich I can connect via NO-IP adress. The problem is that I want to set up portforwarding since i got several services running on my Pi like SSH, torrent webgui, webalbum, etc. I had this already done before long time ago, but I forgot a bit the syntax and cant get to set it up. Router Help says: The Application allows you to do port forwarding, but only have the ports open when data flowing out of the trigger ports. When a program sends data out on outgoing ports called trigger ports, the device then allows incoming data on the open ports specified in your port triggering configuration. 1.Trigger Port Start Trigger Port Start Specify the start port on the device that would trigger the device to open ports for incoming data. 2.Trigger Port End Specify the end port on the device that would trigger the device to open ports for incoming data. You can enter a port number the same as the trigger port start or enter a larger port number to specify a port range. 3.Trigger Traffic Protocol Type Select the trigger traffic type. Open Port Specify all the ports to be opened. It's content could be: A single port only. A port range only. Start open port number and end port number should be separated by "-" . Combined several single port and several port ranges. Each single port or port range should be separated by "," . Open Traffic Protocol Type Select the open traffic type. This are the fields: http://es.tinypic.com/view.php?pic=n5lv1k&s=8 I think this is the syntax 1-7999,8001-9090,9092-65535. But each time I want to add it gives me an error. Any ideas?

• Adventures in Drupal multisite config with mod_rewrite and clean urls

  - by moexu

  The university where I work is planning to offer Drupal hosting to staff/faculty who want a Drupal site. We've set up Drupal multisite with clean urls and it's mostly working except for some weird redirects. If you have two sites where one is a substring of the other then you'll randomly be redirected to the other site. I tracked the problem to how mod_rewrite does path matching, so with a config file like this: RewriteCond %{REQUEST_URI} ^/drupal RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /drupal/index.php?q=$1 [last,qsappend] RewriteCond %{REQUEST_URI} ^/drupaltest RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /drupaltest/index.php?q=$1 [last,qsappend] /drupaltest will match the /drupal line and all of the links on the /drupaltest page will be rewritten to point to /drupal. If you put the end of string character ($) at the end of each rewrite condition then it will always match on the correct site and the links will always be rewritten correctly. That breaks down as soon as a user logs in though because the query string is appended to the url so just the base url will no longer match. You can also fix the problem by ordering the sites in the config file so that the smallest substring will always be last. I suggested storing all of the sites in a table and then querying, sorting, and rewriting the config file every time a Drupal site is requested so that we could guarantee the order. The system administrator thought that was kludgy and didn't address the root problem. Disabling clean urls should also fix the problem but the users really want them so I'd prefer to keep them if possible. I think we could also fix it by using an .htaccess file in each site to handle the clean url rewriting but that also seems suboptimal since it will generate a higher load on the server and the server is intended to host the majority of the university's external facing web content. Is there some magic I can do with mod_rewrite to get it to work? Would another solution be better? Am I doing something the wrong way to begin with?

• Apache with multiple domains, single IP, VirtualHost is catching the wrong traffic

  - by apuschak

  I have a SOAP web service I am providing on a apache web server. There are 6 different clients (IPs) that request data and 3 of them are hitting the wrong domain. I am trying to find a way to log which domain name the requests are coming from. Details: ServerA is the primary ServerB is the backup domain1.com - the domain the web service is on domain2.com - a seperate domain that server seperate content on ServerB ServerA is standalone for now with its own IP and DNS from domain1.com. This works for everyone. ServerB is a backup for the web service, but it already hosts domain2.com. I added entries into the apache configuration file like: <VirtualHost *:443> ServerName domain2.com DocumentRoot /var/www/html/ CustomLog logs/access_log_domain2443 common ErrorLog logs/ssl_error_log_domain2443 LogLevel debug SSLEngine on ... etc SSL directives ... </VirtualHost> I have these for both 80 and 443 for domain1 and domain2 with domain1 being second. The problem is when we switch DNS for domain1 from ServerA to ServerB, 3 out of the 6 clients show up in the debug logs as hitting domain2.com instead of domain1.com and fail their web service request because domain2.com is first in the apache configuration file and catching all requests that don't match other virtualhosts, namely domain1.com. I don't know if they are hitting www.domain1.com, domain1.com (although I added entries for both) or using the external IP address or something else. Is there a way to see which URL they are hitting not just the page request or someother way to see why the first domain is catching traffic meant for the second listed domain? In the meantime, I've put domain1.com higher in the apache configuration than domain2.com. Now it catches the requests for all clients and works, however I don't know what it is catching and would like to make domain2.com the first entry again with a correct entry for domain1.com, for however they are hitting it. Thank you for your help! Andrew

• Updating files with a Perforce trigger before submit [migrated]

  - by phantom-99w

  I understand that this question has, in essence, already been asked, but that question did not have an unequivocal answer, so please bear with me. Background: In my company, we use Perforce submission numbers as part of our versioning. Regardless of whether this is a correct method or not, that is how things are. Currently, many developers do separate submissions for code and documentation: first the code and then the documentation to update the client-facing docs with what the new version numbers should be. I would like to streamline this process. My thoughts are as follows: create a Perforce trigger (which runs on the server side) which scans the submitted documentation files (such as .txt) for a unique term (such as #####PERFORCE##CHANGELIST##NUMBER###ROFL###LOL###WHATEVER#####) and then replaces it with the value of what the change list would be when submitted. I already know how to determine this value. What I cannot figure out, is how or where to update the files. I have already determined that using the change-content trigger (whether possible or not), which "fire[s] after changelist creation and file transfer, but prior to committing the submit to the database", is the way to go. At this point the files need to exist somewhere on the server. How do I determine the (temporary?) location of these files from within, say, a Python script so that I can update or sed to replace the placeholder value with the intended value? The online documentation for Perforce which I have found so far have not been very explicit on whether this is possible or how the mechanics of a submission at this stage would work.

• Nginx Config - I can't access WordPress admin area

  - by WebDevDude

  I am a complete noob when it comes to Nginx, but I'm trying to make the switch over for my WordPress site. Everything works, even the permalink, but I can't access my WordPress admin directory (I get a 403 error). I have my WordPress install in a subfolder, so that complicates things a bit for me. Here is my Nginx config file: server { server_name mydomain.com; access_log /srv/www/mydomain.com/logs/access.log; error_log /srv/www/mydomain.com/logs/error.log; root /srv/www/mydomain.com/public_html; location / { index index.php; # This is cool because no php is touched for static content. # include the "?$args" part so non-default permalinks doesn't break when using query string try_files $uri $uri/ /index.php?$args; } location /myWordpressDir { try_files $uri $uri/ /myWordpressDir/index.php?$args; } location ~ \.php$ { include /etc/nginx/fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/mydomain.com/public_html$fastcgi_script_name; fastcgi_split_path_info ^(/myWordpressDir)(/.*)$; } location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ { access_log off; log_not_found off; expires max; } }

• Developing high-performance and scalable zend framework website

  - by Daniel

  We are going to develop an ads website like http://www.gumtree.com/ (it will not be like this one but just to give you an ideea) and we are having some issues regarding performance and scalability. We are planning on using Zend Framework for this project but this is all that I'm sure off at this point. I don't think a classic approch like Zend Framework (PHP) + MySQL + Memcache + jQuery (and I would throw Doctrine 2 in there to) will fix result in a high-performance application. I was thinking on making this a RESTful application (with Zend Framework) + NGINX (or maybe MongoDB) + Memcache (or eAccelerator -- I understand this will create problems with scalability on multiple servers) + jQuery, a CDN for static content, a server for images and a scalable server for the requests and the rest. My questions are: - What do you think about my approch? - What solutions would you recommand in terms of servers approch (MySQL, NGINX, MongoDB or pgsql) for a scalable application expected to have a lot of traffic using PHP?...I would be interested in your approch. Note: I'm a Zend Framework developer and don't have to much experience with the servers part (to determin what would be best solution for my scalable application)

• Nginx conditional not evaluating correctly

  - by cjc

  I'm running into a weird problem with nginx and how it evaluates conditionals. Here's the relevant configuration: set $cors FALSE; if ($http_origin ~* (http://example.com|http://dev.example.com:8000|http://dev2.example.com)) { set $cors TRUE; } if ($request_method = 'OPTIONS') { set $cors $cors$request_method; } if ($cors = 'TRUE') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Max-Age' '1728000'; } if ($cors = 'TRUEOPTIONS') { add_header 'Access-Test' "$cors"; add_header 'Access-Control-Allow-Origin' "$http_origin"; add_header 'Access-Control-Allow-Methods' 'POST, OPTIONS'; add_header 'Access-Control-Allow-Headers' 'X-Requested-With, X-Prototype-Version'; add_header 'Access-Control-Max-Age' '1728000'; add_header 'Content-Type' 'text/plain'; } So, the conditional blocks never trigger. When I remove the conditions, I see that the "Access-Test" header and the "Access-Control-Allow-Origin" set correctly, but, as noted, enabling the conditionals causes the headers not to be sent. I'm testing by running: curl -Iv -i --request "OPTIONS" -H "Origin: http://example.com" http://staging.example.com/ Am I missing something obvious? I've tried the "if" with and without quotes, etc. This is nginx 1.2.9.

• sporadic routing to another website when opening a common url

  - by user226098

  I have a strange problem in our office: Sometimes when opening a url from one of our projects random url in any browser not the right website shows up but some other website. In most of the cases it redirects to google.com with some parameters like https://www.google.de/?gfe_rd=cr&ei=krOOU8_kGcSKswadyYDQBw&gws_rd=ssl or just the ugly google 404 page). But today it remains on the origial url but shows up the the content of http://debug.netdna-cdn.com/. This happens about 1 time a week and for no apparent reason. Even stranger it only occurs on a single pc in the network. It now happens on two different computers in the network. Both use windows 8. The problem cannot be fixed by clearing the browser cache but by rebooting the pc or using ipconfig /flushdns. So I think it has something to do with the dns cache of the machine. But I have no idea what the reason is for this and how i can figure out how to solve it. Any ideas?

• How to make Microsoft JVM work on Windows 7?

  - by rics

  I am struggling with the following problem. I cannot install MS JVM 3810 properly on Windows 7. When I start Interner Explorer 8 without starting any java 1.1 programs choosing Java custom settings under Internet options causes the crash of the browser. I have some Java 1.1 programs that work well in Internet Explorer 8 on Windows XP after the installation of MS JVM 3810. I know that it is not advised to use this old JVM but it is not a short-term option to port the programs in newer Java since it contains 3rd party components. Complete rewrite is a long-term plan. Strangely jview and appletviewer (jview /a) works from a console so the MS JVM 3810 is not completely busted just IE 8 does not like it. The problem with the appletviewer is that it cannot connect to the server even if both signed and unsigned content in Java custom settings have been set to Enable all. (Since Java custom settings was unreachable due to the crash the modifications - including My computer - were performed through the registry and pre-checked to behave correctly on Windows XP and Internet Explorer 8.) If jview was working then I could at least think of a workaround. Is there a way to configure MS JVM or jview properly on Windows 7? Another options would be: Checking Internet Explorer 9 Beta. Using virtualbox and Windows XP older IE in it. Delaying Windows 7 upgrade. ... Update Finally we have modified all the programs to work parallelly as applet and application as well. This way the programs can still be used from browser on older Windows versions. On Windows 7 the applications are started from the desktop. Installation to all user machine can easily be solved since they already have a large common application drive. The code update is fortunately only a few lines of modification: including a main method in the applet class. Furthermore instead of the starting html page a bat file is used to set the classpath before the startup with jview.

• screen scraper templates for various websites

  - by intuited

  I'm looking specifically for a convenient way to locally archive posts from this and other similar sites. I'd like to separate the question itself from the answers, or maybe crop the question and store it, keeping the page title. Obviously I don't need to store the menu or the various other site interface chrome. The best way to do this would seem to be to associate an XSLT template with a match on the URL and use that template to pull the various relevant informations and format them. My two-part question: Is there a tool specifically built for this task? I.E. something that takes a URL and checks it against a map of path-matching expressions to templates, and outputs the result of applying the template to that resource? xmlto seems to be most of the way there, and could probably just be called from a script that does the pattern-matching, but something already integrated would be more convenient. Is such a URL_pattern-to-XSLT_template map publicly available somewhere? Question 2.5: Is it legal to do this with sites like this one that have public licenses on their content?

• My scanner isn't responding. It is connected to a SCSI interface using Windows XP

  - by Bob

  I have a Microtek ScanMaker 9600XL scanner. The best part about it is that it is 12x17 inches. Wowza! The worst part about it is that I've had it working at one point, with the same cable, same card, same computer, but have since re-installed Windows XP on it. Currently it will turn on, and blink the Power and Ready lights. They should be solid. I've done my best to find documentation for this, but all I've really gotten is the content on the Microtek site. I've tried turning the scanner on, then the PC. Turning the PC on, then the scanner. When I try launching the software it pops up a dialog saying "ScanWizard Pro can't find any scanners! Use SCSI Check to find a scanner." I know the scanner has a pair of little buttons on the back. These cycle up/down a counter. I think it goes 0-7. Any thoughts on what that does, or how to proceed troubleshooting? I think my next step is to try each of those numbers, and do both pc booted first, and scanner booted first for each of those numbers...

• Fix elements within objects at their position? (Prevent movement when resizing)

  - by Skadier

  I would like to know if it is possible to fix elements at their absolute position within custom elements in InDesign CS5? I created a kind of speech bubble and I would like to place a stripline within this bubble to separate two content areas. Just a little scheme to show the desired layout as Pseudo-Markup :D <speech-bubble> <textbox>HEADER SECTION</textbox> <stripline> <textbox>Some other text</textbox> </speech-bubble> I created something like this but with two separate elements which aren't connected. So I have to select both of them in order to move the whole bubble. Then I tried to connect them using Object->Paths->Create linked path but then the stripline moves and the HEADER SECTION moves too. All in all I would like to have a speech bubble which can be resized in order to hold more text but it shouldn't make the HEADER_SECTION larger or move the stripline. Hope you understand what I mean :D Thanks in advance!

• Why is there an extra HDD under /dev being added in my Linux Kernel?

  - by user1279156

  I have created a Linux kernel and for some reason an extra drive is always added at bootup. My hard drive is listed as /dev/sdb. /dev/sda is created too, and it is 8 MB in size. I can't find anything in the kernel config that is creating this, but if I use a different kernel it is not there. Kernel logs show it as an attached SCSI device, looks just like my hard drive but only 8 MB, and has no partition table. It also doesn't appear to be a physical device. I've tried the kernel on many different models of PCs and it is always there. Does anyone know how to remove it? /dev/disk/by-id gives me: scsi-1AMCC_U21413034D98EB000584 scsi-1AMCC_U21413034D98EB000584-part1 scsi-353333330000007d0 scsi-SATA_ST3250312AS_5VY7SH42 scsi-SATA_WDC_WD800JD-60L_WD-WMAM9Y085675 scsi-SATA_WDC_WD800JD-60L_WD-WMAM9Y085675-part1 scsi-SATA_WDC_WD800JD-60L_WD-WMAM9Y085675-part2 hdparm -i /dev/sda gives me an "invalid argument". dd if=/dev/sda of=sda.img the resulting file does not have any content sdparm results: /dev/sda: Linux scsi_debug 0004 Device identification VPD page: Addressed logical unit: designator type: T10 vendor identification, code set: ASCII vendor id: Linux vendor specific: scsi_debug 2000 designator type: NAA, code set: Binary 0x53333330000007d0 Target port: designator type: Relative target port, code set: Binary transport: Serial Attached SCSI (SAS) Relative target port: 0x1 designator type: NAA, code set: Binary transport: Serial Attached SCSI (SAS) 0x52222220000007ce designator type: Target port group, code set: Binary transport: Serial Attached SCSI (SAS) Target port group: 0x100 Target device that contains addressed lu: designator type: NAA, code set: Binary transport: Serial Attached SCSI (SAS) 0x52222220000007cd designator type: SCSI name string, code set: UTF-8 transport: Serial Attached SCSI (SAS) SCSI name string: naa.52222220000007CD

• How to protect folder privacy against unethical network administrators? [closed]

  - by Trevor Trovalds

  I just need a technical solution for the sake of my group's shared passwords, projects, works, etc. safety. Our network has Active Directory with public/groups/users and NTFS permissions, under a Windows Server 2003 which will soon migrate to Windows Server 2008 R2. Our IT crowd is small, consisting of 2 DBAs, 4 designers, 6 developers (including me), 2 netadmins and (a lot of) tech supporters, everyone has local admin rights. Those 2 network admins weren't the ones who set the network up, they just took the lift recently when the previous ones quit. We usually find them laughing at private contents from users stored in the groups AD, sabotaging documents that don't match their personal tastes and, finally, this week we found out they stole a project we (developers and DBAs) were finishing and, long before, they presented it to the CEO as theirs without us knowing. I'm a systems analyst, and initially my group decided to store critical content, like shared passwords, inside encrypted .zip files. Unfortunately we couldn't do the same to the other hundreds of folders and files, which included the stolen project, because the zipping process would take too long for every update. We also tried an encrypted Subversion repository under SSL, but there are many dummies (~38 atm) involved in the projects that have trouble using TortoiseSVN when contributing, and very oftenly we had to fix messed up updates. Well, I think these two give the idea of what we've been trying to reach. So, is there a practical "individual" protection for our extensive data or my hope can already be euthanized? P.S.: Seriously, at the place where I live/work, political corruption gone the wildest, so denounce related options are likely impracticable. Yet both netadmins have strong "political bond" with the CEO and the President, hence their lousy behavior and our failed delation attempts.

• Cron job checking for changes in Git repository

  - by HNygard

  We have just moved our server configs to a Git repository. Therefore there should not be any changes in any of the repository folders. I was thinking about how I could set up a cron job to check for any uncommited changes. How could a cron job be set up to check for changes in a Git repository? Greping the output of the git status command might just do it. Grep and cron jobs are not my strong side. Here are some sample outputs from git status: Standing the folder containing the git repository (e.g. /path/gitrepo/) with changed files: $ git status # On branch master # Changes not staged for commit: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: apache2/sites-enabled/000-default # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # apache2/conf.d/test no changes added to commit (use "git add" and/or "git commit -a") Standing in the folder when there is no changes: $ git status # On branch master nothing to commit (working directory clean) Update: Synced up with origin is not important. There should be no local changes. Local files that must be in place go into the .gitignore file. In addition to the server configs there are also git repos for content (static web sites, web apps, wordpress, etc). None of the repositories should have local changes. We might use Puppet in the long run since its being used for development of one of the web apps.

• lamp -- edit PHP file but doesn't change web output -- including die()

  - by Reid W

  Server is standard Linux server on Amazon Web Services. Cent OS 5/Apache/PHP 5.3. No APC. It's worked fine for over a year, but now when I edit some but not all PHP files on the server using vi, the changes don't affect the web output. For example, I edit myfile.php and put a die() at the top, but when I load the page in my web browser, instead of the die() I see the content that would show up if the die() weren't there. svn updating the file in question doesn't help either. Files are on an Amazon EBS partition symlinked to /var/www/html. Just to reiterate -- this has worked fine for a long time. Restarting apache didn't help, nor did rebooting the server. What's weird is that it's just some of the files but not all. File ownership/permissions are the same for the "good" and "problem" files. I'm not a Linux newbie but am at a complete loss with this, and couldn't find anything on Google either. Any hints would be much appreciated!

• Empty $upstream_http_location variable if response was cached

  - by Ivaldi

  I would like to cache the response of an redirect. (Cache the request to some site which returns a redirect and cache the second request which returns the actual content.) So far my config looks like this: location = /proxy { error_page 301 302 307 = @redir; resolver 8.8.8.8; proxy_pass $arg_url; proxy_intercept_errors on; proxy_cache pcache; proxy_cache_key $arg_url; proxy_cache_valid 200 301 302 307 1d; proxy_cache_min_uses 1; proxy_ignore_client_abort on; proxy_ignore_headers Set-Cookie Expires Cache-Control; } location @redir { resolver 8.8.8.8; # we need to assign $upstream_http_location to another var in order to use it with proxy_pass set $target $upstream_http_location; proxy_pass $target; proxy_cache predirects; proxy_cache_key $upstream_http_location; proxy_cache_valid 200 301 302 307 1d; proxy_cache_min_uses 1; proxy_ignore_headers Set-Cookie Expires Cache-Control; } It works for the first request or without the 30x codes for proxy_cache_valid in the /proxy part, but $target and $upstream_http_location are empty, if the response was cached. Is there a nice solution to cache both requests? Thanks!

• File exists but is unreadable by PHP

  - by Aron

  More than once I have ran into this issue: I have a cache file that is automatically generated by PHP. It contains some generated PHP code. However for some reason the file cannot be read and parsed by PHP. These are the symptoms: File actually exists on file system. Using Terminal you can navigate to the file, view its contents (which are fully intact), etcetc. PHP file_exists() will report that the file exists...which is correct since it does :) Then I include() the file. But when actually parsing the file, PHP will just consider it an empty file. No fatal error, just no PHP code actually executed. Again, its as if the file was completely empty (which I assure you, it is not)... It is not a permissions issue. Permissions are set as needed. Workaround: open the file in Terminal via 'nano' or some other text editor and just save it to the disk again. After that (despite no changes to the content) PHP will run it just fine... As a clarification, I'd like to add that this happens rarely, but frequently enough to be a problem. And even when it does, there are hundreds of other similar files on the same system that work without a problem... If this were an issue affecting only my own scripts, I would consider that there must be a bug in the way I generate the PHP code. But no, the issue has occurred more than once when deploying to a server (usually from Beanstalk repository via FTP). The issue has been present on various servers, Debian and Ubuntu running Zend Community Server. Any ideas? One that crossed my mind was opcode cache-ing (part of Zend Server CE)...could it be that an empty version of the file is cached if it is requested while the write operation is still in progress?

• I can't change mysql port (5.6.12) changing the lines of my.ini (windows 8)

  - by videador

  I was trying to change the port of my mysql server in my local machine but i can't. The version of mysql is 5.6.12, is an installation from wamp and I am on Windows 8. I change these lines in my my.ini file located in (C:\wamp\bin\mysql\mysql5.6.12). [client] #password = your_password port = 3307 socket = /tmp/mysql.sock [wampmysqld] port = 3307 socket = /tmp/mysql.sock key_buffer = 16M max_allowed_packet = 1M The previous values were 3306. Ok then I've reset the server installed, but it doesn't works, the mysql server is still running on 3306. Then, I rename the path of the services with this, to make sure that the my.ini is read by the mysql instance. c:\wamp\bin\mysql\mysql5.6.12\bin\mysqld.exe --defaults-file="C:\wamp\bin\mysql\mysql5.6.12\my.ini" wampmysqld But nothing, it stil doesn't works. My last bullet was to copy the content of my.ini to a file my-default.ini (a file that is placed in C:\wamp\bin\mysql\mysql5.6.12\ and that I don't know what is its mission). However it still doesn't work and the port is still 3306.

• iptables rules for DNS/Transparent proxy with ip exceptions

  - by SlimSCSI

  I am running a router (A Netgear WNDR3700 if that matters) with dd-wrt. For content filtering I am using OpenDNS. I wanted to make sure a user could not bypass OpenDNS by putting in their own name servers, so I have a rule to catch all DNS traffic. iptables -t nat -A PREROUTING -i br0 -p all --dport 53 -j DNAT --to $LAN_IP I did have one computer on the network I wanted to allow past OpenDNS filters. On that machine I manually set the name servers, and created another rule to allow it to pass iptables -t nat -I PREROUTING -i br0 -s 192.168.1.2 -j ACCEPT This worked well. Today, I installed a transparent proxy (squid) on the router and added these rules: iptables -t nat -A PREROUTING -i br0 -s $LAN_NET -d $LAN_NET -p tcp --dport 80 -j ACCEPT iptables -t nat -A PREROUTING -i br0 -s ! $PROXY_IP -p tcp --dport 80 -j DNAT --to $PROXY_IP:$PROXY_PORT iptables -t nat -I POSTROUTING -o br0 -s $LAN_NET -d $PROXY_IP -p tcp -j SNAT --to $LAN_IP iptables -I FORWARD -i br0 -o br0 -s $LAN_NET -d $PROXY_IP -p tcp --dport $PROXY_PORT -j ACCEPT This also works, however the 192.168.1.2 address does not get routed through squid. How can I have 192.168.1.2 (and maybe others in the future) by-pass the port 53 rules, but not the port 80 rules?

• Cannot Add Particular Word to Dictionary

  - by WCWedin

  I am trying to add a particular word to my custom dictionary using Word 2007. (The word happens to be "deserialized".) When I right-click on the word and click Add to Dictionary, the red underline does not go away. When I use the Spelling & Grammar tool from the Review tab on the ribbon, it will stop on that word; clicking the Add to Dictionary button has no effect. Oddly, I am able to add other words to the custom dictionary without a problem. I recently added "deserializes", for instance. I have only encountered this problem with that one particular word. Does anyone know what might be wrong and how I might fix it? Clarifications My document and all its content is set to English (United States). My custom dictionary is set to apply to All Languages, which is the default value. "Serialize" is in the US English default dictionary, but "deserialize" and its various forms is not.
