I downloaded the OVA appliance at https://www.howtoforge.com/downloads/499/ from "How to install Apache, PHP 7.2 and MySQL on CentOS 7.4 (LAMP)" and imported it to VirtualBox 5.2.12 running on CentOS 7.5.1804. The VM runs, but is missing common commands like tcpdump, netstat, ifconfig, etc. I managed to configure the network with nmtui, and now I can reach external resources but can't ping this VM win selinux disabled and firewalld stopped. sshd_config allows all connections. As I look through history in this VM, I see all the commands from the "HowTo" but I can't figure out how to connect to this VM from external sources. Anyone gone through this before?
It should be enough to edit the network configuration file to get it online, you used nmtui which is fine as well as it basically does the same. Maybe virtualbox has some networking issues or it renamed the network interface during import?
