  • Occasional disk I/O errors in SQLite

    - by Alix Axel
    I have a very simple website running PHP and SQLite 3.7.9 (with PDO). After establishing the SQLite connection I immediately execute the following queries: PRAGMA busy_timeout=0; PRAGMA cache_size=8192; PRAGMA foreign_keys=ON; PRAGMA journal_size_limit=67110000; PRAGMA legacy_file_format=OFF; PRAGMA page_size=4096; PRAGMA recursive_triggers=ON; PRAGMA secure_delete=ON; PRAGMA synchronous=NORMAL; PRAGMA temp_store=MEMORY; PRAGMA journal_mode=WAL; PRAGMA wal_autocheckpoint=4096; This website only has one writer and a few occasional readers, so I don't expect any concurrency problems (and I'm even using WAL). Every couple of days, I've seen this error being reported by PHP: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 10 disk I/O error' in ... Stack trace: #0 ...: PDO-exec('PRAGMA cache_si...') There are several things that make this error very weird to me: it's not a transient problem - no matter how many times I refresh the page, it won't go away the database file is not corrupted - the sqlite3 executable can open the database without problems If the following pragmas are commented out, PHP stops throwing the disk I/O exception: PRAGMA cache_size=8192; PRAGMA synchronous=NORMAL; PRAGMA journal_mode=WAL; Then, after successfully reconnecting to the database, I'm able to reintroduce these pragmas and the code with run smoothly for days - until eventually, the same error will occur without any apparent reason. I wasn't able to reproduce this error so far, so I'm clueless about the origin of it. I'm really curious what may be causing this problem... Any ideas? Environment: Ubuntu Server 12.04 LTS PHP 5.4.15 SQLite 3.7.9 Database size: ? 10MiB Transaction (write) size: ? 1KiB EDIT: Might these symptoms have something to do with busy_timeout?

  • Why does ping flooding a domain name freezes and not a direct ip address

    - by CYREX
    I am wondering why, when ping flooding a domain, the ping flood freezes after a couple of seconds then continues and this freeze, unfreeze continues until i stop the ping flood. When i do the same using the ip it does not freeze. NEVER. i did for example sudo ping -f IP (It does not freeze) then i did sudo ping -f DomainName (It freezes after a couple of seconds) Why does ping flooding an IP not freezes and ping flooding the same place using the domain name does freeze. EDIT - What i mean about freezing is that the behavior of the ping flood should send a ping and create a dot (.) for each ping but also remove each dot (.) after receiving the echo request. Looks something like this: .......... <-- This means you just send 10 ping requests. If the requests are answer, for each request answer a dot is removed. The freeze happens when this is sending or receiving. The dots will stay there frozen, like is not receiving or sending any packets. For the PING FLOOD. I do not mean in the evil way of flooding a place, i mean in the testing way. To test the performance/speed of the request send and answered of the ping requests. If you send a ping flood to google's IP for about 10 seconds you would have send about 1000 packets.but if you do it to google's domain name (google.com) it will create the freeze am talking about. IMPORTANT - Do not confuse with flooding a site with ping of death attacks.

  • How to manage sub-domains on WinHost with IIS7 URL Rewrite 2.0?

    - by jrummell
    I'm trying out WinHost and I'm running into some issues with sub-domains. On WinHost, you can have multiple sub-domains per hosting account, but each sub-domain points to the root website. E.g. you can have www.example.com, sub1.example.com, and sub2.example.com but all of them display the content at http://www.example.com/. Other Hosts allow you to point sub-domains to a sub folder in your website. This would allow you to point sub1.example.com to /sub1, sub2.example.com to /sub2 and www.example.com to /. WinHost recommends using an asp/aspx page to redirect http://sub1.example.com to http://sub1.example.com/sub1, which points to /sub1. While that would work, I'd like to not have the subdomain in the url twice. So I tried using IIS7 URL Rewrite to point http://sub1.example.com to /sub1. Ben Powell describes this in detail on his blog. This is great, except Request.ApplicationPath is now /sub1/path/to/current/page.aspx, which breaks ASP.Net Themes (and probably other stuff too). What can I do to fix the ApplicationPath? Is there a better way to accomplish this?

  • 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?

  • Apache Bad Request "Size of a request header field exceeds server limit" with Kerberos SSO

    - by Aurelin
    I'm setting up an SSO for Active Directory users through a website that runs on an Apache (Apache2 on SLES 11.1), and when testing with Firefox it all works fine. But when I try to open the website in Internet Explorer 8 (Windows 7), all I get is "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Authorization: Negotiate [ultra long string]" My vhost.cfg looks like this: <VirtualHost hostname:443> LimitRequestFieldSize 32760 LimitRequestLine 32760 LogLevel debug <Directory "/data/pwtool/sec-data/adbauth"> AuthName "Please login with your AD-credentials (Windows Account)" AuthType Kerberos KrbMethodNegotiate on KrbAuthRealms REALM.TLD KrbServiceName HTTP/hostname Krb5Keytab /data/pwtool/conf/http_hostname.krb5.keytab KrbMethodK5Passwd on KrbLocalUserMapping on Order allow,deny Allow from all </Directory> <Directory "/data/pwtool/sec-data/adbauth"> Require valid-user </Directory> SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL SSLCertificateFile /etc/apache2/ssl.crt/hostname-server.crt SSLCertificateKeyFile /etc/apache2/ssl.key/hostname-server.key </VirtualHost> I also made sure that the cookies are deleted and tried several smaller values for LimitRequestFieldSize and LimitRequestLine. Another thing that seems weird to me is that even with LogLevel debug I won't get any logs about this. The log's last line is ssl_engine_kernel.c(1879): OpenSSL: Write: SSL negotiation finished successfully Does anyone have an idea about that?

  • DirectAccess Server firewall rules blocking ports

    - by StormPooper
    I have configured DirectAccess on my Server 2012 Essentials box and most of it works great - I can remotely access the server via RDP and the default IIS website on port 80. However, I can't access anything that uses other ports. For this example, the Team Foundation Server website. The only way to access it is by accessing http://localhost:8080/tfs on the server directly - even when using http://servername:8080/tfs or http://192.168.1.100:8080/tfs won't work. I've tried adding the ports to the NAT exceptions using Set-NetNatTransitionConfiguration –IPv4AddressPortPool and while that has allowed some ports used internally (Deluge, for example) it hasn't allowed me access to the URL. I think I've narrowed it down to the "DirectAccess Server Settings" Group Policy that is created when configuring DirectAccess. When I disable the link for this GPO, the TFS site works again, but the default IIS site stops working (but RDP still works). I already have rules in the firewall on the server for TFS and before enabling this Group Policy (so before configuring DirectAccess) I could access both sites. Does anybody have any suggestions for things I can change to allow access to both? I've uploaded the full GPO report and my Remote Access Configuration Summary for more details.

  • IIS URL Rewrite HTTP to HTTPS with Port

    - by Andy Arismendi
    My website has two bindings: 1000 and 1443 (port 80/443 are in use by another website on the same IIS instance). Port 1000 is HTTP, port 1443 is HTTPS. What I want to do is redirect any incoming request using "htt p://server:1000" to "htt ps://server:1443". I'm playing around with IIS 7 rewrite module 2.0 but I'm banging my head against the wall. Any insight is appreciated! BTW the rewrite configuration below works great with a site that has an HTTP binding on port 80 and HTTPS binding on port 443, but it doesn't work with my ports. P.S. My URLs intentionally have spaces because the 'spam prevention mechanism' kicked in. For some reason google login doesn't work anymore so I had to create an OpenID account (No Script could be the culprit). I'm not sure how to get XML to display nicely so I added spaces after the opening brackets. < ?xml version="1.0" encoding="utf-8"? < configuration < system.webServer < rewrite < rules < rule name="HTTP to HTTPS redirect" stopProcessing="true" < match url="(.*)" / < conditions trackAllCaptures="true" < add input="{HTTPS}" pattern="off" / < /conditions < action type="Redirect" redirectType="Found" url="htt ps: // {HTTP_HOST}/{R:1}" / < /rule < /rules < /rewrite < /system.webServer < /configuration

  • Setting up ProxyPass for a Virtualmin virtual server

    - by Andy Ibanez
    I am trying to set up my web server so that I can server multiple Ghost.org blogs. I am stuck in one crucial step. To be honest, my knowledge in servers is not so big, so I request your help to do this. Basically, a tutorial I'm reading suggests I set up a VirtualHost in this way: NameVirtualHost *:80 <VirtualHost *:80> ServerName your-url.com ServerAlias www.your-url.com ProxyRequests off ProxyPass / http://127.0.0.1:2368/ ProxyPassReverse / http:/127.0.0.1:2368/ </VirtualHost> So I have gone to the Virtual site on Virtualmin to try to add everything as is. Services Configure Website Edit Directives The problem is, the previous page (Services Configure website) says I can't edit the port: This Apache virtual host belongs to the Virtualmin server linguist.andyibanez.com, so the address, port, base directory and hostname cannot be changed here. And whenever I try to add the ProxyRequests off (the other two can be added fine) directive in Edit Directives manually, I'm simply told that the directive can't be there. So what is the right way to "add" the last three directives in the VirtualHost above to my sub server? Maybe I'm missing a menu item that will help me with this? I request your help as I have looked for a while, Google keeps thinking I want to serve Webmin via Apache when I google "Set up Virtualmin proxypass", and I have no clue what to do.

  • Preventing access to files if a user types the full url on the address bar

    - by bogha
    i have a website, some folders on the websites contains images and files like .pdf , .doc and .docx . the user can easly just type the address in the url to get the file or display the photo http://site/folder1/img/pic1.jpg then boom.. he can see the image or just download the file my question is: how to prevent this kind of action, how can i guarantee a secure access of the files. any suggestions UPDATE TO CLARIFY MY IDEA i don't want any user who is browsing the website to get access to these files normally by just writing the URL of the file. those files are a CV files, they are being uploaded by the users to a specific folder on the server which we host outside the company. those files are only being viewed by the HR people through a special system. that's the scenario we want. i don't want a WEB GEEK who just wants to see what files has been uploaded to this folder to download them easly to his/her computer and view them or publish them on the internet. i hope you got my idea

  • Setting up multiple servers for one domain

    - by Joseph Torraca
    So I am starting up a new website and I was wondering how to set up 5 servers to host the site. I have already purchased 5 Apple XServes, one will be used as a test server and the other 4 will be for the live site. So I have read some website on the internet and they all reference using one server and installing software onto it and have that server do the load balancing. I have also read that you could use a hardware, rack-mounted system and plug the servers into that. The load balancer would then distribute the load. So I have a few questions about each: 1) How do you set up the software version and have the other servers as "slaves" and have one "master" to direct traffic? 2) Which of the two options above are more reliable, and better suited for a startup that doesn't have many users per month, yet(hopefully)? 3) Is there a theoretical max limit of servers that can be connected to a software load balancing system? Note: Obviously this will change from software to software, but in terms of the server being able to handle it? 4) In your own opinion, what are you using for your sites? Have you had any problems setting up that system or operating it once its running? Are there any things you would stay away from if you had to start over? 5) I also purchased a Apple RAID system, so if you are familiar with it, is there any way to connect it to multiple Xserves so they all serve the same data? I'm a little confused on this, so thanks for all your help and being patient with me. Note: Take it easy on me, I am learning this as I go along, so I may have used terms incorrectly or explained things that don't really make sense. Sorry. P.S. If you need me to supply the specs on the servers to determine which system makes the most sense, I can post them for you.

  • SQL Server 2008 login problem with ASP.NET application: Failed to open the explicitly specified data

    - by eulerfx
    I am running SQL Server 2008 Express Edition on Windows Server 2008 with an ASP.NET application which must access the server. The ASP.NET application is associated with an application pool that runs on the NetworkService account. This account in turn has a Login and User record on SQL Server in the required database. When I attempt to run the ASP.NET website I get a blank page and when viewed in the error log, I seem to be getting this information event record: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: myLocalMachine] The connection string has Trusted_Connection=True; and the required database specified. When I explicitly specify the user name and password I get another login error stating the password is incorrect, even though the same un/pw combination works through SQL Server Management studio. The NETWORK SERVICE account seems to have all the required privileges for the database. Also, I made a test ASP.NET website project which does a simple select from a table in that database, and using the same config file I am not getting the error and it seems to work. Is it something to do with trust levels then, because the original ASP.NET web app references various DLLs including open source libraries. Also, the application does not seem to be able to write to the event log itself, throwing a security exception, even though everything in the config files, including machine.config states the app is in full trust.
