  • firehol (firewall) with bridge: how to filter

    - by Leon
    I have two interfaces: eth0 (public address) and lxcbr0 with 10.0.3.1. I have a LXC guest running with ip 10.0.3.10 This is my firehol config: version 5 trusted_ips=`/usr/local/bin/strip_comments /etc/firehol/trusted_ips` trusted_servers=`/usr/local/bin/strip_comments /etc/firehol/trusted_servers` blacklist full `/usr/local/bin/strip_comments /etc/firehol/blacklist` interface lxcbr0 virtual policy return server "dhcp dns" accept router virtual2internet inface lxcbr0 outface eth0 masquerade route all accept interface any world protection strong #Outgoing these protocols are allowed to everywhere client "smtp pop3 dns ntp mysql icmp" accept #These (incoming) services are available to everyone server "http https smtp ftp imap imaps pop3 pop3s passiveftp" accept #Outgoing, these protocols are only allowed to known servers client "http https webcache ftp ssh pyzor razor" accept dst "${trusted_servers}" On my host I can connect only to "trusted servers" on port 80. In my guest I can connect to port 80 on every host. I assumed that firehol would block that. Is there something I can add/change so that my guest(s) inherit the rules of the eth0 interface?

  • Rails 3 shows 404 error instead of index.html (nginx + unicorn)

    - by Miko
    I have an index.html in public/ that should be loading by default but instead I get a 404 error when I try to access http://example.com/ The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved. This has something to do with nginx and unicorn which I am using to power Rails 3 When take unicorn out of the nginx configuration file, the problem goes away and index.html loads just fine. Here is my nginx configuration file: upstream unicorn { server unix:/tmp/.sock fail_timeout=0; } server { server_name example.com; root /www/example.com/current/public; index index.html; keepalive_timeout 5; location / { try_files $uri @unicorn; } location @unicorn { proxy_pass http://unicorn; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } } My config/routes.rb is pretty much empty: Advertise::Application.routes.draw do |map| resources :users end The index.html file is located in public/index.html and it loads fine if I request it directly: http://example.com/index.html To reiterate, when I remove all references to unicorn from the nginx conf, index.html loads without any problems, I have a hard time understanding why this occurs because nginx should be trying to load that file on its own by default. -- Here is the error stack from production.log: Started GET "/" for 68.107.80.21 at 2010-08-08 12:06:29 -0700 Processing by HomeController#index as HTML Completed in 1ms ActionView::MissingTemplate (Missing template home/index with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml, :haml], :formats=>[:html], :locale=>[:en, :en]} in view paths "/www/example.com/releases/20100808170224/app/views", "/www/example.com/releases/20100808170224/vendor/plugins/paperclip/app/views", "/www/example.com/releases/20100808170224/vendor/plugins/haml/app/views"): /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/paths.rb:14:in `find' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/lookup_context.rb:79:in `find' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/base.rb:186:in `find_template' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/render/rendering.rb:45:in `_determine_template' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/actionpack-3.0.0.beta4/lib/action_view/render/rendering.rb:23:in `render' /usr/local/rvm/gems/ruby-1.9.2-rc2/gems/haml-3.0.15/lib/haml/helpers/action_view_mods.rb:13:in `render_with_haml' etc... -- nginx error log for this virtualhost comes up empty: 2010/08/08 12:40:22 [info] 3118#0: *1 client 68.107.80.21 closed keepalive connection My guess is unicorn is intercepting the request to index.html before nginx gets to process it.

  • CREDSSP 500 errors

    - by Andy Milsark
    Hello all, We are experience a 500 http error when trying to run remote powershell on a win 2008 R2 server. I have run enable-wsmancredssp for both client and server roles on this machine. I have also run "winrm quickconfig". Also the allowfreshcredentials delegation group policy is setup correctly as well. There are active listeners running and credssp is enabled for client and service. I can connect with kerberos (by not specifing authentication type), but the following remote powershell command fails: Enter-PSSession -ComputerName serverX -credential domain\user -Authentication Credssp Error: Enter-PSSession : Connecting to remote server failed with the following error message : The WinRM client received an HTTP server error status (500), but the remote service did not include any other information about the cause of the failure. For more information, see the about_Remote_Troubleshooting Help topic. At line:1 char:16 I have not been able to find any useful information on how to troubleshoot this. I have restarted Winrm, rebooted, disabled and re-enabled credssp. Please help.

  • Apache: Setting up a reverse proxy configuration with SSL with url rewriting

    - by user1172468
    There is a host: secure.foo.com that exposes a webservice using https I want to create a reverse proxy using Apache that maps a local http port on a server internal.bar.com to the https service exposed by secure.foo.com Since it a web service I need to map all urls so that a path: https://secure.foo.com/some/path/123 is accessible by going to: http://internal.bar.com/some/path/123 Thanks. I've gotten this far: <VirtualHost *:80> ServerName gnip.measr.com SSLProxyEngine On ProxyPass / https://internal.bar.com/ </VirtualHost> I think this is working except for the url rewriting. Some resources I've found on this are: Setting up a complex Apache reverse proxy Apache as reverse proxy for https server

  • Does Apache2 Configured as ReverseProxy Hide Cookies Set by Backend Servers?

    - by Ianthe
    I use Apache 2.2.16 as Reverse Proxy. For a static website, I don't have any issues. However, when began to use cookies, I've noticed that cookies are not being sent to the client. Here's a snippet of my config: <VirtualHost *:80> ServerName app.somewhere.com:80 ServerAlias app ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /app http://10.x.x.x/app ProxyPassReverse /app http://10.x.x.x/app <Location /> Order allow,deny Allow from all </Location> </VirtualHost> But when I try to access the app server directly, I receive the cookies ok. Is this an expected behaviour for Apache2? I'm using HAProxy for another application that sends cookies to the client and I get all of them.

  • How to optimize sandboxie for faster application loading

    - by user23950
    I'm referring to this one: http://www.sandboxie.com/index.php?DownloadSandboxie Do you know of any alternatives that might be better than this software. And if you don't know of any alternative. Can you show me how can I make it faster to load firefox. Or any other browser. Because it really makes application incredibly slow at loading when you run them inside a sandbox. I've also seen lots from here: http://superuser.com/questions/57129/alternative-to-sandboxie-for-64-bit-systems Do you know of any other?

  • Single sign-on for SharePoint to MySite?

    - by Chris W
    I've got a fairly simple SharePoint 2010 farm set up: 2 WFE servers with Network Load Balancing hosting the main portal site. As per Microsoft's best practice recommendations I've set up My Sites in a separate web application. As some of the user base are not using domain joined PCs they have to login once for the portal (http://portal) and then again when the access My Sites since they're crossing in to a separate web application on a separate host (http://mysite). Portal & MySite are both hosted on the same physical WFE servers. Is there an easy way to set up some thing to stop this happening and just have them login once? I understand that there's plans for us to deploy ISA in the not too distant future - could we use ISA to manage authentication to the two sites so that the users only need to log in once?

  • Default virtual server does not work

    - by Luc
    Hello, I have 4 Name Virtual Hosts on my apache configuration, each one using proxy_http to forward request to the correct server. They work fine. <VirtualHost *:80> ServerName application_name.domain.tld ProxyRequests Off ProxyPreserveHost On ProxyPass / http://server_ip/ ProxyPassReverse / http://server_ip/ </VirtualHost> I then tried to add a default NameVirtualHost to take care of the requests for which the server name does not match one of the four others. Otherwise a request like some_weird_styff.domain.tld would be forwarded to one of the 4 VH. I then added this one: <VirtualHost *:80> ServerAlias "*" DocumentRoot /var/www/ </VirtualHost> At the beginning it seemed to work fine, but at some point it appears that the requests that should be handed by one of the 4 regular hosts is "eaten" by the default one !!! If I a2dissite this default host, everything is back to normal... I do not really understand this. If you have any clue... thanks a lot, Luc

  • Debian 6 Internet connection sharing aka IP masquerade not working

    - by Rautamiekka
    The problem: the computers [Xbox 360 and a Kubuntu 12.04.1 laptop] can't access Internet through a recently-installed desktopless Debian 6 laptop (which is wirelessly connected to a WLAN station) but addresses are successfully given by dnsmasq. The attempts: 1.1) /etc/dnsmaq.conf conffed according to http://wiki.debian.org/HowTo/dnsmasq: add lines interface=eth0 dhcp-range=192.168.0.50,192.168.0.150,255.255.255.0,12h 1.2) Follow http://www.cyberciti.biz/faq/rhel-fedora-linux-internet-connection-sharing-howto/ and use their script to setup iptables. 2) Follow the Ubuntu Internet Gateway Method (iptables) at https://help.ubuntu.com/community/Internet/ConnectionSharing recommended and which worked at Share internet in Linux. The Debian laptop was rebooted many times and between each attempt, with and without the script auto-executing via /etc/rc.local. While adding the iptables-restore command to that file I disabled the script.

  • How do I access site.project.rails (running on host) from VMWare fusion?

    - by Johnny Mnemonic
    I have a rails app setup and running on my snow leopard MacBook - the app is being served by Passenger. As part of the setup they had me add entries for 127.0.0.1 site.project.rails in my hosts file so I could reach the site from site.project.rails I can't for the life of me figure out how to get the app show up in VMWare. I have XP setup and browse to http://site.project.rails and I can't get it to show up. I setup a basic rails app, being served at localhost:3000 by webrick, I can get that to load by visiting my hosts ip (http://192.168.1.1:3000/). I added the same hosts I added on my Mac to Windows. I also Bridged the network under settings for the VM. What am I missing?

  • Libre Office/Writer PDF export: white borders appear between lines even after setting borders to none

    - by Yttric
    My document prints ok (exactly as it appears on the screen in Libre Office), but when I export to PDF and view the PDF on screen there are white borders around each text or picture object. Here's a sample snapshot from PDF/Preview: http://imgur.com/TWip5 I've tried selecting a paragraph and changing the border property to None as described in Libre Office help (http://help.libreoffice.org/Common/Borders), setting the "Line arrangement Default" to "Set no borders". But borders set by the Format dialog don't correspond to the borders I see in PDF/Preview. In PDF/Preview the border appears on line boundaries. Borders set in Format appear around each picture, for example. What am I doing wrong?

  • What are the differences between the Fujitsu ScanSnap S300 and the S1300?

    - by Techboy
    Please can you tell me what the technical differences are between the Fujitsu ScanSnap S300 and the S1300 scanners? S300 = http://www.fujitsu.com/emea/products/scanners/scansnap/tmpl_scanners_scansnap-S300.html S1300 = http://www.fujitsu.com/emea/products/scanners/scansnap/tmpl_scanners_scansnap-S1300.html The only difference I can see is that the S300 has a CCD Image Sensor and the S1300 has a CIS Image Sensor. Other than that, the resolutions, pages per minute and physical sizes of both models are exactly the same. If so, is there a reason why I would want the S1300 instead of the cheaper S300? I just want a scanner for duplex document scanning, for home use (documents, receipts, etc.).

  • Redirect anything within /attachments/ directory up one level but also removing anything after /attachments/

    - by Rich Staats
    WordPress creates an attachment page for any images uploaded through the post editor and "attached" to that post. After migrating a site, those attachment pages no longer exist, and we now have around 1000 links pointed at 404's. So, I was looking to find a way to do a redirect for any url that has /attachement/ in it's string and then push that url back up one level (which happens to be the post page). so for instance: http://mysite.com/2012/news/blog-post-title/attachment/image-page/ (which doesnt exist) will go to http://mysite.com/2012/news/blog-post-title/ (which does exist). Along with redirecting up one level, I also need to remove anything after /attachment/ (in this case the "image-page." Any suggestions? Thanks in advance

  • Trouble with Debian Lenny and Sphinx

    - by Ando
    I've very basic understanding of linux systems, but I've a server which was setup a while ago to host some web apps. Recently I decided to test out and implement Sphinx but unfortunately I cant get the install to work. I'm running a Debian Lenny distro and when I try to install sphinx it says - checking MySQL include files... configure: error: missing include files. ****************************************************************************** ERROR: cannot find MySQL include files. Check that you do have MySQL include files installed. The package name is typically 'mysql-devel'. If include files are installed on your system, but you are still getting this message, you should do one of the following: 1) either specify includes location explicitly, using --with-mysql-includes; 2) or specify MySQL installation root location explicitly, using --with-mysql; 3) or make sure that the path to 'mysql_config' program is listed in your PATH environment variable. To disable MySQL support, use --without-mysql option. ****************************************************************************** I do have mysql 5.1 installed but I can't find the include files, AND one more thing..

  • performance block countries using iptables /netfilter

    - by markus
    It's easy to block IPs from country using iptables (e.g. like http://www.cyberciti.biz/faq/block-entier-country-using-iptables/). However I read that the performance can go down if the deny list get too large. An alternative is installing the iptables geoip patch or using ipset ( http://www.jsimmons.co.uk/2010/06/08/using-ipset-with-iptables-in-ubuntu-lts-1004-to-block-large-ip-ranges/) instead of iptables. Does anyone have experience with the various approaches and can say something about the performance differences ? Are there are other ways to block country IPs in linux which I did't mentioned above?
