Enabling Shared Configuration in Windows 2022 Server

Shared Configuration in Windows Server primarily refers to the Internet Information Services (IIS) feature that allows multiple web farm servers to synchronize and use a single set of configuration (applicationHost.config and administration.config). In recent days while performing Windows server 2016 to Windows server 2022, We faced issue in IIS Manager was crashing after enabling Shared configuration and had to contact Microsoft support team.

After investigation from and Microsoft support confirmed, they have a bug in windows 2022 server IIS Manager while saving shared configuration.

With help from Microsoft Support Team, We were able to identify the alternate solution to fix the issue.

Following are steps to fix the issue.

Add the permissions to MachineKeys under C:\ProgramData\Microsoft\Crypto\RSA\

Add the below users from local machine

Everyone - Read & Execute, List folder contents, Read
SYSTEM - All Permissions
IIS_IUSRS - Read & Execute, List folder contents, Read
USERS - Read & Execute, List folder contents, Read
Administrator - All Permissions

Copy the exported IIS-Transfer-Key (which has 2016 RSA Machine Keys) to Windows 2022 Server and keep it in C Drive.

Run the following script in Windows 2016 server.

On the 2016 server, Run elevated PowerShell:

$folder = "C:\IIS-Key-Transfer" $aspnet = "$env:windir\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe" New-Item -ItemType Directory -Path $folder -Force & $aspnet -px "IisWasKey" "$folder\IisWasKey.xml" -pri & $aspnet -px "IisConfigurationKey" "$folder\IisConfigurationKey.xml" -pri Both must report Succeeded! . Securely transfer those XML files to the 2022 server. On the 2022 server First attempt to import over the temporary containers: $folder = "C:\IIS-Key-Transfer" $aspnet = "$env:windir\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe" & $aspnet -pi "IisWasKey" "$folder\IisWasKey.xml" -exp & $aspnet -pi "IisConfigurationKey" "$folder\IisConfigurationKey.xml" -exp Once you import, you will see the below message. Microsoft (R) ASP.NET Core, an open-source web development framework | .NET RegIIS version 4.0.30319.0 Administration utility to install and uninstall ASP.NET Core, an open-source web development framework | .NET on the local machine. Copyright (C) Microsoft Corporation. All rights reserved. Importing RSA Keys from file.. Succeeded! Microsoft (R) ASP.NET Core, an open-source web development framework | .NET RegIIS version 4.0.30319.0 Administration utility to install and uninstall ASP.NET Core, an open-source web development framework | .NET on the local machine. Copyright (C) Microsoft Corporation. All rights reserved. Importing RSA Keys from file.. Succeeded!

c. Restart the Windows Process Activation Service and World Wide Web Services.

d. Enable Shared Configuration on the servers.

Give the Path, Service Account, Username, Password and Encryption Password.

This should enable the shared configuration and you should see the sites in the server.

Disable azure network accelerator

Recently, I came across an issue in azure QA account, the credit was getting utilized more than the expected numbers, because of this the instances were shutting down before the due date.

This issue was finally addressed after couple of research. The problem was with the network accelerator this was consuming a huge amount of credit.

When tried to disable the network accelerator, it showed an error as this is supported for VM series D/DSv2, D/DSv3, E/ESv3, F/FS, FSv2, and Ms/Mms only.

I came across a KB article to execute following command in azure shell to disable network accelerator.

az network nic update --name --resource-group --accelerated-networking false

In the above command line, replace nic_name and resource_group_name with existing names mentioned in your azure portal.

Hope this helps you.

Happy computing... :)

$ gcc svndumpsanitizer.c -o svndumpsanitizer

For complete help.

$ ./svndumpsanitizer --help

A typical command would look something like this:

Hi,

Wireless driver installation for Toshiba Tecra z40.

sudo apt-get install linux-headers-generic build-essential

wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.19-rc1/backports-3.19-rc1-1.tar.gz

tar -zxvf backports-3.19-rc1-1.tar.gz

cd backports-3.19-rc1-1

make defconfig-iwlwifi

make

sudo make install

And you will need firmware

wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7260-ucode-23.15.10.0.tgz

tar zxvf iwlwifi-7260-ucode-23.15.10.0.tgz

sudo cp iwlwifi-*.ucode /lib/firmware

Reboot

If you realize that your wifi doesn't work in the future, it is likely that a kernel update occured and you will need to

cd backports-3.19-rc1-1

make clean

make defconfig-iwlwifi

make

sudo make install

Ubuntu 10.04 ethernet controller issue - Dell Optiplex

After the installation of Ubuntu 10.04 on Dell optiplex 790, we found that the Ethernet controller is not working on it.

After some research I found that there are no Ethernet driver e1000e was installed as there was a bug in that & resolved very soon.

The driver e1000e installation steps as follows.

Download the driver e1000e.
unzip the package.
Make a cd to the src folder inside the e1000e folder.
execute make command before that ensure gcc installed.
execute make install command.
execute modprobe e1000e to add the module.
Now you should see the network should be working fine.

We found this issue only in 10.04 as we were using this distribution version frequently. We have only tested this on Ubuntu 10.04.

Happy Networking...Enjoy... :)

Update-grub : Dual Boot - Grub Load

2011-02-25T19:35:00.001+05:30

Hi,

From last 2days I was trying to upgrade my laptop from Debian Lenny 5.0 to Debian Squeeze 6.0, As there was some problem with my internet connection I was not able to do it.

After 24hrs I was able to connect to internet. Now my machine is upgraded with Debian Squeeze 6.0 finally and thought of sharing a small issue faced with boot loader after the upgradation.

When upgradation was proceeding it asked to select the partition to install the boot-loader. It showed the two partition /dev/sda (Ubuntu partition) & /dev/sda2 (Debian Partition) as I was not sure, installed the boot-loader on /dev/sda. After the complication the laptop rebooted and I was not able to find the Ubuntu 10.04 in my grub. I found only the debian kernel boot loader. After some try I figured it out, if it needs to updated run the command update-grub. Run this command on live machine. Also check where the master boot record is pointed and run the update command.

By this the grub will read the partition table re-generate the grub.cfg as below.

cyclotron:~# update-grub

How to Restrict postfix recipient in zimbra

2010-12-16T13:45:00.007+05:30

Restrict postfix recipient in zimbra

This will show how you can modify postfix to restrict who can send to certain address in your domain such as distribution like team@domain.com.

These change will most likely not persist between upgrades!!!

zimbra/conf/postfix_recipient_restrictions.cf. Also permissions on files created in /opt/zimbra/postfix/conf/ will be changed.

Create permitted sender list as zimbra user under /opt/zimbra/postfix/conf/

permitted_sender List :- This file contains domains list OR User mail list, Only protected senders can send mail to this domains OR users.

# vim /opt/zimbra/postfix/conf/permitted_senders

localhost                         OK

myhost.com                    OK

mydomain.com                OK

username@domain.com   OK

Create protected recipient file as zimbra user under /opt/zimbra/postfix/conf/

protected_recipients :- This file contains email address that can only receive from permitted senders

# vim /opt/zimbra/postfix/conf/protected_senders

myteam@domain.com                 permitted_senders_list

protect_users@domain.com         permitted_senders_list

Include the important setting to /opt/zimbra/postfix/conf/main.cf

permitted_senders_list=check_senders_access hash:/opt/zimbra/postfix/conf/permitted_senders, reject

smtpd_restriction_classes = permitted_senders_list,local_only

FYI :- The changes in main.cf will not survive after the upgrade of zimbra.

Now add the this restriction on the top of all line.

# vim /opt/zimbra/conf/postfix_recipient_restrictions.cf

check_recipient_access hash:/opt/zimbra/postfix/conf/protected_recipients

Reload the settings

/opt/zimbra/postfix/sbin/postmap /opt/zimbra/postfix/conf/permitted_senders

/opt/zimbra/postfix/sbin/postmap /opt/zimbra/postfix/conf/protected_recipients

/opt/zimbra/postfix/sbin/postmap /opt/zimbra/postfix/conf/postfix_recipient_restrictions.cf

/opt/zimbra/postfix/sbin/postfix  reload

FYI :- This configuration can also used in normal postfix..

Migrate / Backup your mails to gmail / google apps.

2010-10-25T17:30:00.002+05:30

Hi All...

Here are some worked examples on how to do the synchronization to google hosted email system.

Step 1.
Create directory to where you can store password files.

Step 2.
Make a list of password files. (A password file is one with only the password stored in it)

Step 3.
Check the version of imap-sync using in your computer. The synchronization works only with versions above 1.261. If you are using debian / ubuntu use the below command to check the version.

apt-cache policy imapsync
imapsync:
Installed: 1.286+dfsg-3ubuntu1
Candidate: 1.286+dfsg-3ubuntu1

Step 4.
After the installation of imapsync go to the password created directory.

Step 5.
To synchronize the mail from any domain to gmail OR google hosted apps use the following command. (Make sure imap has been enabled in the Gmail account)

$ imapsync --host1 mail.domain.com --user1 source@domain.com --noauthmd5 --passfile1 /path/to/passwordfile --host2 imap.gmail.com --user2 destination@domain.com --passfile2 /path/to/passwordfile --port2 993 --ssl2 --folder 'INBOX' 'INBOX.Sent'

Step 6.
If the given credentials are correct, the command will look like the following.

with perl 5.10.1
Mail::IMAPClient 3.21
IO::Socket 1.31
IO::Socket::SSL
Digest::MD5 2.39
Digest::HMAC_MD5

Zimbra Installation on Debian, Ubuntu & Linux

2009-12-29T12:17:00.006+05:30

Hi All...

Zimbra installation on any linux is very easy. It keeps system administrator in peace. If you really want to feel it INSTALL IT ;-) Enjoy.

Download Zimbra OS from http://www.zimbra.com/community/downloads.html

Before configuring setup the dns for the domain you want to configure the email on local machine or any dns servers. Example : Everydns, Xname.org.. ( This may take few hours).

Installation of bind ( Dns ) Configuration on debian / ubuntu.

apt-get install bind ( Installs bind packages on debian box )

add your ip address to /etc/hosts.

The first line of the file defines the IP address of localhost as follows: 127.0.0.1 localhost.localdomain localhost

The second line will include the private IP address and hostname of the server: 1.2.3.4(Public Ip Address) mail.domain-name.com mail

ex :- 127.0.0.1 localhost.localdomain localhost
Your Public-Ip-Address mail.domain-name.com mail

Go To /etc/bind/ copy db.local file /var/cache/bind/'domain'.db = ( 'domain' = Your Domain Name. Any .com , .in, .org,) It would be better to configuring on local machine as dns server take few hours to resolve.

Change the domain name and ip address. ( Dont forget to add your ip add in /etc/hosts ).

Tip :- Properly mention the ( DOT (.) , Open Bracket & Close Bracket () in the /var/cache/bind/domain-name.db file. These are the main important things techies will go mad. ;-) unless they are very professional.

Add the domain zone in /etc/bind/named.conf.local

zone "example.com" {

type master;

file "/var/cache/bind/example.com.db"

};

; BIND data file for local loopback interface
