This tutorial describes the steps to renew the SSL Certificate of the ISPConfig 3 control panel. There are two alternative ways to achieve that:
- Create a new OpenSSL Certificate and CSR on the command line with OpenSSL.
- Renew the SSL Certificate with the ISPConfig updater
I'll start with the manual way to renew the ssl cert.
1) Create a new ISPConfig 3 SSL Certificate with OpenSSL
Login to your server on the shell as root user. Before we create a new SSL Cert, backup the current ones. SSL Certs are security sensitive so I'll store the backup in the /root/ folder.
tar pcfz /root/ispconfig_ssl_backup.tar.gz /usr/local/ispconfig/interface/ssl chmod 600 /root/ispconfig_ssl_backup.tar.gz
Now create a new SSL Certificate key, Certificate Request (csr) and a self signed Certificate.
openssl genrsa -des3 -out ispserver.key 4096 openssl req -new -key ispserver.key -out ispserver.csr openssl x509 -req -days 3650 -in ispserver.csr \ -signkey ispserver.key -out ispserver.crt openssl rsa -in ispserver.key -out ispserver.key.insecure mv ispserver.key ispserver.key.secure mv ispserver.key.insecure ispserver.key
Restart Apache to load the new SSL Certificate.
service apache2 restart
2) Renew the SSL Certificate with the ISPConfig installer
The alternative way to get a new SSL Certificate is to use the ISPConfig update script.
Download ISPConfig to the /tmp folder, unpack the archive and start the update script.
cd /tmp wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz tar xvfz ISPConfig-3-stable.tar.gz cd ispconfig3_install/install php -q update.php
The update script will ask the following question during update:
Create new ISPConfig SSL certificate (yes,no) [no]:
Answer "yes" here and the SSL Certificate creation dialog will start.
Get ready for the turnaround

Follow these steps to disable IPv6 on CentOS. Edit the /etc/sysctl.conf file, I will use the nano editor here:
And add the following line at the end of the file:
net.ipv6.conf.all.disable_ipv6 = 1
to load the new settings.
The next step is to edit the network card configuration file (/etc/sysconfig/network-scripts/ifcfg-eth*) and add or edit the setting IPV6INIT so that it is set to "no".
Now edit the file /etc/sysconfig/network:
And set the NETWORKING_IPV6 option to "no":
Then restart the server.

The “Get Windows 10” icon in the tray has been installed as part of the KB3035583 Windows update.
To remove that icon permanently uninstall this update in the windows software center. The Windows update function might offer this update again in future, so don't forget to hide it in Windows update so that it does not come back.
If you still see the icon after uninstalling and a reboot, then check if there are still files of the update in C:\Windows\System32\GWX. If that's the case, delete this directory.
