i was planning on getting a server from codera with no control panel and then install webmin but the codero support told me that to install it i would need to order kvm over ip which costs more monthly than cpanel…is that true…why would i need kvm over ip?
All you would need is SSH access in order to log into your server, and install the desired packages.
You could either install just Webmin, or you could install the full Virtualmin stack (which includes Webmin), by downloading the install.sh script at the Download page linked above.
