Hi, the server that I'm installing the CMS onto is a Linux / Windows shared machine, equipted with .Net 2.0

I had followed the exact steps described in the section "Installation on shared hosting server" from the developer's guide 3.1a

After I've set up the database and copied all files to the server's root, I ran the online set up by going to the <my domain>/Default.aspx page. And I see the following.
(xxx represents the server user account)

The NTWEB\xxx account is not granted with Modify permission on folder \\10.0.0.104\xxx\public\. Although this is not an error, it's highly recommended that you configure these permissions.

The permission for the public folder is set to 775 (rwxrwxr-x)

So I try to chmod the folder to 777 (rwxrwxrwx) and hit the "Test permissions again" button. And I see this error

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

Then it suggest me to add debug="true" to the page.

So I opened up public/CMSInstall/install.aspx and added debug = true after <%@ Page Language="C#"

Then I go back to <my domain>/Default.aspx and it magically show up the set up screen.

Then I input the the database server information into the set up wizard with "Create Kentico Server Object" checked.

Then the sql scripts were running for a while and give me the following:

The installer couldn't update the web.config file on your server. This may be caused by limited file system permissions. Please open your web.config file manually in Notepad and add the following line inside the <connectionStrings></connectionStrings> section below the <clear /> line: (xxxx are the correct value on my server by the way)

<add name="CMSConnectionString" connectionString="Persist Security Info=False;database=xxxxxx;server=xxxxxx;user id=xxxxxxxxx;password=xxxxxxx;Current Language=English;Connection Timeout=240;"/>

then i added the connection string to web.config and hit next and it give me another error: The connection string you added doesn't match. Make sure, the connection string is correct.

So, instead of retrying the same steps, I restored the original web.config and give it write permissions. Then I drop all the previousely created database objects and ran the online set up wizard again, but same error saying connection string doesnt' match.

Now I'm stuck here.

Ok, so I somehow fixed the conection string issue by correcting the string.

Now I hit next again and it give me the following again.

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.


After that, I tried <my domain>/Default.aspx again and I can see a link that points me to the Site Manager, so I click that link, and try to create a new web site using a wizard, then I ended up with the following error.

[ImportProvider.CreateTemporaryFiles]: Data not found or the package is not a valid export package.

I guess it's the files/folders permissions that give me these troubles. But I'm not sure which folder should be granted which permission under the linux environment.

I granted 777 to the public folder already, and the CMS sub folders, some have 755 and some have less permission.

Your help of explaining how to set up appropriate permissions in linux chmod would be very helpful.
