[VirtualBox 6][Centos 8] Troubleshoot - unbale to enable second network adaptor on Centos 8 in VirtualBox



[Problem]

After installing Centos 8 on VirtualBox 6.x version, I realised that second network adpator never actually up and running which makes only use first network adaptor.

[Issue Check]

- When First log in to Centos, it is showing only First network adapter regardless of network type(NAT, Host only or Bridge).





- Tried to activate second network using NetworkManager but it doesn't even show the Network interface but ip list is showing second network.

nmtui

[Solution]
The solution to this is simply create scripts for second network interface in /etc/sysconfig/network-scripts.

1. cd /etc/sysconfig/network-scripts
2. sudo cp enp0s3 enp0s8
3. sudo vi enp0s8



4. reboot

Once it reboots, second network is up and running with ip address assigned as expected.

This post is to provide an instruction on how to set up LDAPS (LDAP over SSL) on Domain Controller using single-tier CA hierachy. Reasons for Enabling LDAPS By default, LDAP communications between client and server applications are not encrypted. This means that it would be possible to use a network monitoring device or software and view the communications traveling between LDAP client and server computers.

As simple BIND exposes the users’ credentials in clear text, use of Kerberos is preferred. If simp...
