• redirect web app results to own application

  - by vbNewbie

  Is it possible to redirect a web apps results to a second application? I cannot parse the html source. It contains the javascript functions that execute the queries but all the content is probably server side. I hope this makes sense. The owner has made the script available but I am not sure how this helps. Can I using .net call the site and redirect results perhaps to a file or database? the app accesses one of googles apis and performs searches/queries and returns results which are displayed on the site. Now all the javascript functions that perform these queries are listed in the source but I do not know javascript so it does not make much sense to me. I have used the documentation which uses the oauth protocol to access the api and have implemented that in my web app but it took me nearly a week to get the request token right and now to send requests to the api, sometimes I get one result back and sometimes none. It is frustrating me and the owner of the web app has given use of his script but he says all that happens is that my browser interacts with the google api and not his server. So I thought why not have my web app call his, since his interacts with the API flawlessly and have the results sent to my app to save in a database. I have very little experience here so pardon my ignorance

• Need help/guidance about creating a desktop application with gui

  - by Somebody still uses you MS-DOS

  I'm planning to do an Desktop application using Python, to learn some Desktop concepts. I'm going to use GTK or Qt, I still haven't decided which one. Fact is: I would like to create an application with the possibility to be called from command line, AND using a GUI. So it would be useful for cmd fans, and GUI users as well. It would be interesting to create a web interface too in the future, so it could be run in a server somewhere using an html interface created with a template language. I'm thinking about two approaches: - Creating a "model" with a simple interface which is called from a desktop/web implementation; - Creating a "model" with an html interface, and embeb a browser component so I could reuse all the code in both desktop/web scenarios. My question is: which exactly concepts are involved in this project? What advantages/disadvantages each approach has? Are they possible? By naming "interface", I'm planning to just do some interfaces.py files with def calls. Is this a bad approach? I would like to know some book recommendations, or resources to both options - or source code from projects which share the same GUI/cmd/web goals I'm after. Thanks in advance!

• Twitter API similar to Google Alert

  - by Felix Perdana

  I am trying to create a web application which have a similar functionality with Google Alerts. (by similar I mean, the user can provide their email address for the alert to be sent to, daily or hourly) The only limitation is that it only gives alerts to user based on a certain keyword or hashtag. I think that I have found the fundamental API needed for this web application. https://dev.twitter.com/docs/api/1/get/search The problem is I still don't know all the web technologies needed for this application to work properly. For example, Do I have to store all of the searched keywords in database? Do I have to keep pooling ajax request all the time in order to keep my database updated? What if the keyword the user provided is very popular right now that might have thousands of tweets just in an hour (not to mention, there might be several emails that request several trending topics)? By the way, I am trying to build this application using PHP. So please let me know, what kind of techniques I need to learn for such web app (and some references maybe)? Any kind of help will be appreciated. Thanks in advance :) Regards, Felix Perdana

• ASP.NET MVC 3 Hosting :: Deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed

  - by mbridge

  You can built sample application on ASP.NET MVC 3 for deploying it to your hosting first. To try it out first put it to web server where ASP.NET MVC 3 installed. In this posting I will tell you what files you need and where you can find them. Here are the files you need to upload to get application running on server where ASP.NET MVC 3 is not installed. Also you can deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed like this example: you can change reference to System.Web.Helpers.dll to be the local one so it is copied to bin folder of your application. First file in this list is my web application dll and you don’t need it to get ASP.NET MVC 3 running. All other files are located at the following folder: C:\Program Files\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies\ If there are more files needed in some other scenarios then please leave me a comment here. And… don’t forget to convert the folder in IIS to application. While developing an application locally, this isn’t a problem. But when you are ready to deploy your application to a hosting provider, this might well be a problem if the hoster does not have the ASP.NET MVC assemblies installed in the GAC. Fortunately, ASP.NET MVC is still bin-deployable. If your hosting provider has ASP.NET 3.5 SP1 installed, then you’ll only need to include the MVC DLL. If your hosting provider is still on ASP.NET 3.5, then you’ll need to deploy all three. It turns out that it’s really easy to do so. Also, ASP.NET MVC runs in Medium Trust, so it should work with most hosting providers’ Medium Trust policies. It’s always possible that a hosting provider customizes their Medium Trust policy to be draconian. Deployment is easy when you know what to copy in archive for publishing your web site on ASP.NET MVC 3 or later versions. What I like to do is use the Publish feature of Visual Studio to publish to a local directory and then upload the files to my hosting provider. If your hosting provider supports FTP, you can often skip this intermediate step and publish directly to the FTP site. The first thing I do in preparation is to go to my MVC web application project and expand the References node in the project tree. Select the aforementioned three assemblies and in the Properties dialog, set Copy Local to True. Now just right click on your application and select Publish. This brings up the following Publish wizard Notice that in this example, I selected a local directory. When I hit Publish, all the files needed to deploy my app are available in the directory I chose, including the assemblies that were in the GAC.

• How to bridge Debian guest VM to VPN via Cisco AnyConnect Client running on Windows Vista host

  - by bgoodr

  I am running Cisco Anyconnect VPN Client version 2.5.3054 on a laptop running Windows Vista Home Premium (version 6.0.6002) Service Pack 2. I am running the VMware Player version 4.0.2 build-591240. The host operating system running under VMware Player is Debian 6.0.2.1 i386. The laptop is connected to a wireless connection, and I can browse the web from Windows Vista using Firefox just fine. I am able to boot into the Debian VM and open up a browser and access websites on the WAN from within the VM just fine. I can ping real Linux hosts on my LAN via: ping <lan_system>.local where <lan_system> is the hostname returned from uname -a on that system on my LAN. From a DOS CMD shell, I am able to ping hosts that exist on the remote network served by the Cisco AnyConnect Client's VPN network (and without the .local suffix applied as above): ping <remote_system> However, from within the Debian VM, I expect to be able to also ping those same remote hosts (<remote_system>) that are tunnelled over the VPN set up by Cisco AnyConnect Client. Let's say that I can ping a <remote_system> called flubber from a DOS CMD prompt just fine. When I execute Linux ping command from inside the Debian VM via: ping flubber It returns immediately with this output: ping: unknown host flubber For reference since I suspect it will be useful, here is the output of the route print command from the DOS CMD prompt: route print =========================================================================== Interface List 30 ...00 05 9a 3c 7a 00 ......

• KVM guest io is much slower than host io: is that normal?

  - by Evolver

  I have a Qemu-KVM host system setup on CentOS 6.3. Four 1TB SATA HDDs working in Software RAID10. Guest CentOS 6.3 is installed on separate LVM. People say that they see guest performance almost equal to host performance, but I don't see that. My i/o tests are showing 30-70% slower performance on guest than on host system. I tried to change scheduler (set elevator=deadline on host and elevator=noop on guest), set blkio.weight to 1000 in cgroup, change io to virtio... But none of these changes gave me any significant results. This is a guest .xml config part: <disk type='file' device='disk'> <driver name='qemu' type='raw'/> <source file='/dev/vgkvmnode/lv2'/> <target dev='vda' bus='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> There are my tests: Host system: iozone test # iozone -a -i0 -i1 -i2 -s8G -r64k random random KB reclen write rewrite read reread read write 8388608 64 189930 197436 266786 267254 28644 66642 dd read test: one process and then four simultaneous processes # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct 1073741824 bytes (1.1 GB) copied, 4.23044 s, 254 MB/s # dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/vgkvmnode/lv2 of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 14.4528 s, 74.3 MB/s 1073741824 bytes (1.1 GB) copied, 14.562 s, 73.7 MB/s 1073741824 bytes (1.1 GB) copied, 14.6341 s, 73.4 MB/s 1073741824 bytes (1.1 GB) copied, 14.7006 s, 73.0 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 6.2039 s, 173 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 32.7173 s, 32.8 MB/s 1073741824 bytes (1.1 GB) copied, 32.8868 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9097 s, 32.6 MB/s 1073741824 bytes (1.1 GB) copied, 32.9688 s, 32.6 MB/s Guest system: iozone test # iozone -a -i0 -i1 -i2 -s512M -r64k random random KB reclen write rewrite read reread read write 524288 64 93374 154596 141193 149865 21394 46264 dd read test: one process and then four simultaneous processes # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 1073741824 bytes (1.1 GB) copied, 5.04356 s, 213 MB/s # dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=1024 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=2048 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=3072 & dd if=/dev/mapper/VolGroup-lv_home of=/dev/null bs=1M count=1024 iflag=direct skip=4096 1073741824 bytes (1.1 GB) copied, 24.7348 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7378 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.7408 s, 43.4 MB/s 1073741824 bytes (1.1 GB) copied, 24.744 s, 43.4 MB/s dd write test: one process and then four simultaneous processes # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 10.415 s, 103 MB/s # dd if=/dev/zero of=test bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test2 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test3 bs=1M count=1024 oflag=direct & dd if=/dev/zero of=test4 bs=1M count=1024 oflag=direct 1073741824 bytes (1.1 GB) copied, 49.8874 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8608 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.8693 s, 21.5 MB/s 1073741824 bytes (1.1 GB) copied, 49.9427 s, 21.5 MB/s I wonder is that normal situation or did I missed something?

• Using the ASP.NET Membership API with SQL Server / SQL Azure: The new &ldquo;System.Web.Providers&rdquo; namespace

  - by Harish Ranganathan

  The Membership API came in .NET 2.0 and was a huge enhancement in building web applications with users, managing roles, permissions etc.,  The Membership API by default uses SQL Express and until Visual Studio 2008, it was available only through the ASP.NET Configuration manager screen (Website – ASP.NET Configuration) or (Project – ASP.NET Configuration) and for every application, one has to manually visit this place to start using the Security and other settings.  Upon doing that the default SQL Express database aspnet.mdf is created to store all the user profiles. Starting Visual Studio 2010 and .NET 4.0, the Default Website template includes the Membership API controls as a part of the page i.e. When you create a “File – New – ASP.NET Web Application” or an “ASP.NET MVC Application”, by default the Login/Register controls are enabled in the MasterPage and they are termed under “ApplicationServices” setting in the web.config file with connection string pointed to the SQL Express database. In fact, when you run the default website and click on “Logon” –> “Register”, and enter the details for registration and click “Register”, that is the time the aspnet.mdf file is created with the tables for Users, Roles, UsersInRoles, Profile etc., Now, this uses the default SQL Express database within the App_Data folder.  If you want to move your Membership information to some other database such as SQL Server, SQL CE or SQL Azure, you need to manually run the aspnet_regsql command and specify the destination database name. This would create all the Tables, Procedures and Views required to handle the Membership information.  Thereafter you can change the connection string for “ApplicationServices” to point to the database where you had run all the scripts. Now, enter “System.Web.Providers” Alpha. This is available as a part of the NuGet package library.  Scott Hanselman has a neat post describing the steps required to get it up and running as well as doing the basic changes  at http://www.hanselman.com/blog/IntroducingSystemWebProvidersASPNETUniversalProvidersForSessionMembershipRolesAndUserProfileOnSQLCompactAndSQLAzure.aspx Pretty much, it covers what the new System.Web.Providers do. One thing I wanted to clarify is that, the new “System.Web.Providers” add a lot of new settings which are also marked as the defaults, in the web.config.  Even now, they use SQL Express as the default database.  But, if you change the connection string for “DefaultConnection” under connectionStrings to point to your SQL Server or SQL Azure, Membership API would now be able to create all the tables, procedures and views at the destination specified (i.e. SQL Server or SQL Azure). In my case, I modified the DefaultConneciton to point to my SQL Azure database.  Next, I hit F5 to run the application.  The default view loads.  I clicked on “LogOn” and then “Register” since I knew there are no tables/users as of then.  One thing to note is that, I had put “NewDB” as the database name in the connection string that points to SQL Azure.  NewDB wasn’t existing and I would assume it would be created before the tables/views/procedures for Membership are created. Once I clicked on the “Register” to register my first username, it took a while and then registered as well as logged in me in.  Also, I went to the SQL Azure Management Portal and verified that there exists “NewDB” which has just been created I could also connect to the SQL Azure database “NewDB” from Management Studio and found that the tables now don’t have the aspnet_ prefix.  The tables were simply Users, Roles, UsersInRoles, Profiles etc., So, with a few clicks and configuration change, I could actually set up the user base for my application on SQL Azure and even make the SessionState, Roles, Profiles being stored in SQL Azure database. The new System.Web.Proivders also required MARS (MultipleActiveResultSets=true) setting since it uses Entity Framework for the DAL operations.  Also, the “Project – ASP.NET Configuration” screen can be used to further create/manage users/roles etc., although the data is stored on the remote database. With that, a long pending request from the community to have the ability to configure and use remote databases for Application users management without having to run the scripts from SQL Express is fulfilled. Cheers !!!

• How to troubleshoot web server lock-up (Debian Squeeze)

  - by Ryan

  Every once in a while, my web server slows so significantly, it seems locked up. Can't SSH in, no sites being served. It's a VPS that started out as Debian 5 which I upgraded to testing (squeeze). It's a typical LAMP set-up with the sole purpose of running a couple of wordpress sites. One time when it locked up, I got to one of the sites, but it was wordpress complaining it couldn't establish a database connection. So it seemed as if something was really chewing up the CPU and mysqld either timed out, or possibly failed and couldn't restart. But since I couldn't SSH in I feel more inclined to attribute it to CPU. But the only processes running now, aside from OS and kernel stuff: apache mysqld python (for fail2ban) sshd exim4 It has 512M of RAM and 1.5 GB of swap. Every time I check on it, it has plenty of free memory and is using virtually no swap (usually 2-3M). And since I am running fail2ban I don't think I'm getting ddosed. I did find this in my logwatch email this morning (it locked up late last night, when there would have been very little traffic): 6 Time(s): [<ffffffff810a0ebc>] ? oom_kill_process+0x7e/0x23d 6 Time(s): [<ffffffff810a1505>] ? __out_of_memory+0x12a/0x141 6 Time(s): [<ffffffff810a1586>] ? out_of_memory+0x6a/0x94 I didn't find anything else suspicious. It can't be my provider's host because I can SSH in and restart the VM, and everything seems fine. Anybody know which logs I should start poring through to find the core of my problem? Thanks guys.

• Configure IPv6 routing

• Why does nmap ping scan over a VPN link return all hosts alive?

  - by ewwhite

  I'm curious as to why running an nmap -sP (ping scan) on a remote subnet linked via a Cisco site-to-site IPSec tunnel returns "host up" status for every IP in the range. [root@xt ~]# nmap -sP 192.168.108.* Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2012-11-22 14:08 CST Host 192.168.108.0 appears to be up. Host 192.168.108.1 appears to be up. Host 192.168.108.2 appears to be up. Host 192.168.108.3 appears to be up. Host 192.168.108.4 appears to be up. Host 192.168.108.5 appears to be up. . . . Host 192.168.108.252 appears to be up. Host 192.168.108.253 appears to be up. Host 192.168.108.254 appears to be up. Host 192.168.108.255 appears to be up. Nmap finished: 256 IP addresses (256 hosts up) scanned in 14.830 seconds However, a ping of a known-down IP simply times out or doesn't return anything... [root@xt ~]# ping 192.168.108.201 PING 192.168.108.201 (192.168.108.201) 56(84) bytes of data. --- 192.168.108.201 ping statistics --- 144 packets transmitted, 0 received, 100% packet loss, time 143001ms Is there a more effective way to scan live devices connected in this manner?

• How should secret files be pushed to an EC2 (on AWS) Ruby on Rails application?

  - by nikc

  How should secret files be pushed to an EC2 Ruby on Rails application using amazon web services with their elastic beanstalk? I add the files to a git repository, and I push to github, but I want to keep my secret files out of the git repository. I'm deploying to aws using: git aws.push The following files are in the .gitignore: /config/database.yml /config/initializers/omniauth.rb /config/initializers/secret_token.rb Following this link I attempted to add an S3 file to my deployment: http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/customize-containers.html Quoting from that link: Example Snippet The following example downloads a zip file from an Amazon S3 bucket and unpacks it into /etc/myapp: sources: /etc/myapp: http://s3.amazonaws.com/mybucket/myobject Following those directions I uploaded a file to an S3 bucket and added the following to a private.config file in the .elasticbeanstalk .ebextensions directory: sources: /var/app/current/: https://s3.amazonaws.com/mybucket/config.tar.gz That config.tar.gz file will extract to: /config/database.yml /config/initializers/omniauth.rb /config/initializers/secret_token.rb However, when the application is deployed the config.tar.gz file on the S3 host is never copied or extracted. I still receive errors that the database.yml couldn't be located and the EC2 log has no record of the config file, here is the error message: Error message: No such file or directory - /var/app/current/config/database.yml Exception class: Errno::ENOENT Application root: /var/app/current

• PORT FORWARDING TO PUT MY WEB SERVER ON THE INTERNET

  - by Chadworthington

  I went to http://canyouseeme.org/ to check to see what my external IP address. Regardless of what port I enter, it tells me that the port is blocked. I have a LinkSys router that basically has the default settings with the exception that I have WEP encrptin setup and I have forwarded a few ports, including 80 and 69. I forwarded them to the 192.x.x.103 IP address of the PC which is running IIS. That PC runs Symantec Endpoint Protection, which I right mouse clicked in the tray to Disable. These steps used to make my PC visible so I could host my own web site in IIS on port 80, or some other port, like 69. Yet, the Open Port tool cannot see my IP when it checks eiether port and when I navigate to http://my external ip/ I get "page cant be displayed" At first I was thinking that maybe Comcast is blocking port 80, but 69 doesnt work eiether. I do not see any other blockking set up in my router and, as I mentioned, I went with teh defaults except where discussed. This is a corporate PC and Symantec End Point Protecion is new to it (this previously worked on teh same PC with Symantec Protection Agent), but I thought that disabling Sym End Pt from the tray, that that would effectively neutralize it. I do not have the rights to kill the program itself. Any suggestions on what else to try to make my PC externally visible?

• Registering publicly Mail server and Web server in a free dns server

  - by Bruno Vieira

  I'm trying to host the e-mails and the site of our company into our private server. I've already followed the Gentoo Virtual Mailhosting System with Postfix Guide and my mail server is working (actually it sends mails for the local users and for external users it goes to spam) and know how to set an Apache 2 server. What I don't know (and I mean really don't) is how to make them public. I did some research and found that I should ask my ISP to change the reverse DNS to my company domain in order to prevent my mails to be marked as spam, they are doing. I already know I have to configure a DNS Server, it seems like my register provider already has one but I don't know how I can configure CNET, A, MX, TXT and all those tags (Is it tags the name?) and If I must do some other configuration on my server. My Server: Linux mail 3.2.21-gentoo #1 SMP My /etc/hosts: 127.0.0.1 mail.example.com.br example example.com.br ::1 mail.example.com.br mail example.com.br My /etc/conf.d/hostname: hostname ="mail" What am I missing? If there's a guide about how to configure I would really be grate. Thanks in advance for the help. Cheers

• ssh timeout issue connecting to an EC2 instance on OS X

  - by mamusr

  I am new to AWS and not a networking expert but curious to know more about it. I created a VPC with a public subnet only. Then i created an EC2 instance using an Ubuntu 14.04 64-bit pv AMI image (ami-e84d8480) as well generating the key pair needed to connect to it through ssh. I followed amazon's instructions to connect to an EC2 instance via ssh which did not work. Here is my attempted input and debug log: Running on OS X 10.9.4 user$ ssh -vvv -i key.pem [email protected] OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011 debug1: Reading configuration data /etc/ssh_config debug1: /etc/ssh_config line 20: Applying options for * debug1: /etc/ssh_config line 102: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx] port 22. debug1: connect to address xxx.xxx.xxx.xxx port 22: Operation timed out ssh: connect to host xxx.xxx.xxx.xxx port 22: Operation timed out To attempt to resolve the issue: I enabled the SSH port. Tried different usernames other than ubuntu, like ec2-user and root. Initially set an inbound ssh rule in the security group to connect to only my ip address. When that did not work, i changed it to allow any ip to connect. But those actions did not fix the problem. Here are my guesses as to what i am missing in getting the EC2 instance connection to work. My etc/ssh_config file may be preventing the connection from taking place. I may have missed an important networking detail when setting up the VPC. I do not have a public ip address specified for the instance. I am connecting through the private ip address. My questions for the community: Am i going about it the wrong way connecting to the instance through the private ip address? if so, do i need to specify a public ip address for it to connect or some other method?

• cPanel web server redundancy advice?

  - by crgnz

  At present I operate a (reasonably low volume) web-hosting service with a Centos 5.3 server running cPanel/WHM. I would like to implement a level of redundancy such that in the event of server failure, I can restore service with a minimum of effort in less than 60 minutes. I also want to setup a secondary DNS that cPanel will replicate with. My current idea is to kill two birds with one stone by: My current server is called "www1" Purchase an identical server (HP DL360 G4) with mirrored disks. Call this server "www2" Install Centos 5.4 (or perhaps I should install 5.3 to be identical with www1) Install cPanel/WHM on this server and fully license it Setup www1 and www2 cPanel to replicate DNS with each other Setup a nightly replication script that does the following: a) rsync's the /home directory from www1 to www2 b) dumps all MySQL databases on www1 and copies them to a temp folder (with root access only) on www2 c) triggers a script to run on www2 that restores the MySQL dumps Thus each night a fully working copy of all the websites and MySQL databases is copied to www2. I do not have enough knowledge of MySQL replication to understand if it works safely and transparently with cPanel. Thus I propose the mysql dump/copy/restore due to not knowing any better! In the event that www1 dies a horrible death, I envisage that I could login to www2, change the IP addresses to those that www1 had, and presto, the websites are available again. The advantage of this idea is that it is fairly simple and "low tech" and thus does not require an expert sysadmin to setup and monitor (I am NOT an expert sysadmin) The disadvantage of this idea is that up to a full days worth of data changes would be lost. I think this would be acceptable to the sorts of customers I host at the moment. The other disadvantage would be having to pay for a full cPanel license, but I am comfortable with that cost, so for now all I want to discuss are technical considerations. Is this a sound scheme?

• SSL in IIS 7 on a subdomain in a web farm

  - by justjoshingyou

  I have been having one of the most frustrating days in my entire IT career. I am trying to install an SSL certificate on a subdomain in a web farm. http://shop.mydomain.com needs to ALWAYS be forced to https://shop.mydomain.com I have a temporary cert issued from verisign on shop.mydomain.com I have installed the cert on the server. The website for shop.mydomain.com is set as a host header in IIS with the DNS entry pointed to the same IP as mydomain.com - which is our load balancer. I actually have 2 load balancers (as needed by our ISP). One redirects all traffic on port 80 out to the different servers on port 80. The other pushes out port 443 to the servers on port 443. shop.mydomain.com is to be the only site protected by SSL at this time. When I add the binding and I navigate to https://shop.mydomain.com it pops up with a warning about the cert being invalid (assumed because this is a test cert), and then it sends the user to http. So, I checked the box "Require SSL and it redirects to http://shop.mydomain.com/default.aspx and displayes an ASP.NET 404 error message. (not the IIS 404 error) I tried removing the binding on the site to port 80 as well with no luck. I am nearly ready to crawl under my desk into the fetal position. How on earth do I make this work? I can't even get it to work on one machine, let alone in the load balanced environment.

• Bounce backs from web-generated e-mails are missing

  - by JerSchneid

  We use Google Apps to host my company's mail. On our website, we send some e-mails on behalf of our users. In those e-mails we include lines like this: Return-Path: <[email protected]> Sender: <[email protected]> Sending the messages works great (passes SPF tests), but in the case that the message is sent TO an invalid e-mail address, we expect to get a bounce back message sent to "[email protected]". That message never arrives. (If we send an e-mail manually from within the gmail interface to the same bad e-mail, the message does arrive). We used to receive the bounce back messages as expected, but it seems like they are always quietly blocked now (not in spam or anything). Is there a new policy that blocks bounce backs when the "From" does not match the "Return-Path" or something? We would really like to get these bounce-backs to verify the delivery of the messages. Is there any way to prevent them from being blocked?! Thank you!

• Windows 2008 R2 AWS CloudFormation Elastic beanstalk configuration

  - by Webmonger

  I'm looking for some configuration advice. I have a need for a load balanced windows environment with shared media across all instances that are hosting the app. The best explanation i can give is that there will be multiple Windows 2008 server with IIS hosting the app going through an ELB to load balance. Users must be able to upload content (images, video etc...) to the site that will be hosted. When a user uploads media it needs to be kept on a shared location so all windows IIS instances can access the files, I can't host the files on S3 because of the app architecture so they need to be in a place where all IIS server will have access. In addition I need to run an update each IIS server instance that updates a local memory cache when SQL data is updated. I was thinking of a configuration like this: [ELB] - [Win 2008 IIS (multiple servers)] - [Win 2008 File & SQL Server(possibly RDS?)] Does this configuration make sense? If not could you provide an idea of how I should configure it. Thanks in advance

• Webservice randomly dropping connections - possibly due to firewall nonevent data?

  - by adam

  I have a hosted webapp which requests data from a REST webservice in our office. Each page calls one (or several) webservices, which go from our host, via our firewall (a Watchguard Firebox) to a server in our office. All of a sudden, the app has dramatically slowed. We have determined that the webservice is timing out at random when called externally (it's fine when called within the office network). I'm pretty certain it's our connection which is dropping the webservice call, so I've written a quick php/curl script which calls the webservice over many iterations and shows the various timings. Below is an example output, showing both a failed and a successful call (with a 5 second timeout): http_code namelookup_time connect_time pretransfer_time starttransfer_time total_time 1 0 0.000096 0.0342 0.0000 0.0000 0.0342 2 200 0.000052 0.0332 0.1327 0.1751 0.1752 As per iteration #1 above, failed requests seem to be failing between connect and pretransfer. I'm not sure if this shows that the connection is successfully past the firewall, or could the firewall still cause an issue? Our firewall is showing a series of nondata event log messages for the relevant access rule. Our IT team tells me these are routine, although I can find no mention of these in Google. I'm not sure if this fits in between connect and pretransfer. Having elinated the webservice server (by testing internally) and the live webapp (by testing different code on different external servers, I am left suspecting the connection to the office. Could the firebox nondata events be causing a problem between connect and pretransfer?

• Configuring DNS and IIS for multiple domains on a single server

  - by RichardS

  I might be over complicating this but...I am hosting several websites and dns for the domains on a single server: domain1.net domain1.com domain2.net I have three items which I'm trying to work out whether to achieve by DNS, by IIS hostnames(bindings), or by IIS redirect. 1. Where I have domain1.net and domain1.com, I want everything from both (all emails and web requests) to just point to the domain1.net. Can I do this at the DNS level, or do I have to set up the email as forwarders on the email server and the domain as a hostname in IIS? For example: [email protected] [email protected] www.domain1.com www.domain1.net 2. I want to make sure that requests for domain1.net and www.domain1.net both resolve to the same place. Should this be done with DNS or with multiple hostnames, or with IIS redirects? 3. If I then want to have one webmail site serving all of domains (webmail.domain1.net, webmail.domain2.net), is it best to this with a cname in DNS or with host headers in IIS?

• Running docker in VPC and accessing container from another VPC machine

  - by Bogdan Gaza

  I'm having issues while running docker in AWS VPC. Here is my setup: I've got two machines running in VPC: 10.0.100.150 10.0.100.151 both having an elastic IPs assigned to them, both running in the same internet enabled subnet. Let's say I'm running a web server that serves static files in a container on the 10.0.100.150 machine the container: IP: 172.17.0.2 port 8111 is forwarded on the 8111 port on the machine. I'm trying to access the static files from my local machine (or another non-VPC machine also tried an EC2 instance not running in the VPC) and it work flawlessly. If I try to access the files from the other machine (10.0.100.151) it hangs. I'm using wget to pull the files. Tried to debug it with tcpdump and ngrep and that I have seen is that the request reaches the container. If I ngrep on the host machine I see the requests going in but no response going back. If I ngrep on the container I see the requests going in and the response going back. I've tried multiple iptables setups (with postrouting enabled, with manually forwarding ports etc) but no success. Help in any way - even debugging directions would be much appreciated. Thanks!

• cannot reach munin port on other AWS instance

  - by Amedee Van Gasse

  2 AWS instances, in the same region but different availability zones, one is in regular EC2 and the other is in VPC, both have an Elastic IP, both are 64bit Amazon Linux AMI 2014.03.1. Both are running munin-node. The instance in the VPC is running munin-cron. I have added incoming TCP and UDP port 4949 to the security groups of both instances. On the munin node, I added an allow-line with the IP address (regular expression) of the munin server to /etc/munin/munin-node.conf. I bind munin-node to any interface using host *. Then I did sudo service munin-node restart. Then I ran netstat. $ sudo netstat -at | grep munin tcp 0 0 *:munin *:* LISTEN So the port is open there. On the munin server AND on the munin node: $ nmap AMAZON-IP -p 80,4949 | grep tcp 80/tcp open http 4949/tcp closed munin On the munin node: $ nmap localhost -p 80,4949 | grep tcp 80/tcp open http 4949/tcp open munin So from the outside, the http port is open (Apache is running) but the munin port is closed. The node can't even reach the munin port on it's own public IP address, but it can on localhost. I added port 80 as a sanity check, to be sure that there is network connectivity at all. So what am I overlooking here?
