I have the installer from the HP website and I've copied it to the firewall, but it's an RPM. pfSense doesn't seem to have RPM installed.
As explained before it isn´t there and will be never there, it is used by the packet manager from Linux
and not BSD.
Has anyone used the utility, or can you tell me how to install RPM?
No one can do it ever, since pfSense is based on FreeBSD and FreeBSD own it first.
You willing is likes to install a .msi file on a Atari or MaxOS.
